    MULTILAYER LINING FABRIC WITH IMPROVED CHARACTERISTICS AND THESE FULL CLOTHING ACCESSORIES
    The present invention relates to a multilayer lining fabric having improved elasticity and stretchability properties. Moreover, the present invention relates to a multi-layer lining material which improves the safety characteristics of the fabric. In a further embodiment, the invention relates to apparel, in particular work apparel, comprising a multi-layer lining fabric.
    Lining fabrics, particularly for clothing as used in a particular field, such as clothing worn during sports, or clothing worn in a work environment, are subject to the need to meet certain requirements Due to the fact that such clothing often has to protect the wearer against conditions of uncomfortable weather (low temperature, external moisture that occurs as a result of snow or rainfall), it must have a Include outer layer that protects against such conditions. On the other hand, the physical conditions during exercise or when working in the fresh air are characterized by a great amount of body movements (or movements of only certain parts of the body, eg the arms, the upper part of the body, the legs and / or or the lower part of the body) and, in conjunction with this, a shooter of the body. Both can cause discomfort to the wearer of the garment when the outer (protective) layer of the garment is coated with an inner lining fabric. An example of such a lining fabric is the warp knit fabric available on the market from Engtex AB. Mullsjö, Sweden, under the trade name "ENGTEX". The feed, in fact, allows such light bodily movements only to a limited extent (or even prevents such movements) due to a lack of elasticity and recoverability of the feed material. This is particularly true for liners made from the aforementioned warp-knitted fabrics that have been conventionally placed within the protective layer in two or more layers one above the other, with the warp directions of one layer parallel to those of each of the other lining layers ,
    Moreover, sweat produced by the body under sports conditions or working conditions is removed from the skin of the wearer only in a slowed-down manner or not at all. As a result, a moist lining rubs against the skin during body movements, which, in addition to the discomfort of the wearer, causes irritation to the skin of the wearer or even worse conditions such as skin inflammation.
    [0004] One of the specific properties of such liners placed one over another in a plurality of layers was that such a multi-layer lining fabric could be used as a protective fabric for workers operating chain saws: when all layers parallel to one another (ie, the chain direction of each layer was parallel to the chain direction of each other layer) and were well secured together by hemming, the resulting multi-layer lining fabric could prevent persons operating chain saws in their working environment , were injured by their chainsaw. This was due to the fact that after cutting through the outer protective layer of workers' work garment pants, the threads of the lining layers were pulled into the chainsaw and could stop the operation of the chain saw within a few moments, thereby preventing it in that the workers were injured by the motor-operated chains of the saw.
    What remained, however, was the apparent lack of elasticity and stretchability of the lining material, which caused an unacceptable lack of comfort for wearers of the clothing when worn in a sports or work environment.
    [0006] Thus, it has been an object of the present invention to increase the elasticity and stretchability of a multi-layered lining fabric and thus provide more comfort to wearers equipped with garments which have such a multi-layer lining material. Includes fabric. Moreover, it was another object of the invention that the moisture transport (resulting from sweating of the wearer) from the skin of the wearer to the environment through the multi-layered lining fabric is improved so that skin irritation or even inflammation ceases to exist occur.
    In addition, it was another object of the invention to improve the protective properties of the multilayer lining material against chainsaw injuries of a person working with a chain saw, making work accidents less likely when work clothing, provided with the multi-layer lining fabric of the invention is carried in a chainsaw work environment.
    Finally, it was a further object of the invention to provide apparel comprising the multi-layer lining fabric according to the invention, thereby enabling a better wearing comfort for the wearer, for example in the case of sports apparel or work clothing and in particular work clothing for chains saw-workers and forest workers.
    It has surprisingly been found in the context of the present invention that the above-mentioned objects can be achieved together by a multilayer lining fabric in which two or more layers of a warp-knitted fabric are combined to form a lining material through a stack of two or more such warp-knit fabric layers whose warp directions are twisted from one layer to the next by a certain angle. When a stack of such twisted lining fabrics is loosely stitched together, the resulting multi-layer lining fabric in a garment has greatly increased elasticity and can stretch during movements of the wearer of such clothing, thereby providing improved comfort.
    In addition, it has been found that apparel comprising the multi-layer lining fabric of the invention presents surprisingly better protection against chainsaw injuries due to a better blocking performance of the chain saw by the threads of the multilayer lining -Stoffes: The chainsaw is - better than the chucks of the prior art - stopped by the multilayer lining fabric according to the invention not only in cases of chainsaw cuts perpendicular to the axis of the trouser legs, but also in cases of chainsaw cuts in A direction diagonal to the axis of the pant legs: The requirements of the European and national standards for Personal Protective Equipment (PPE) requirements and of DIN (EN) 381-2 and -5 are met by the multi-layer lining material and clothing according to the present invention and diagonal cuts, which as standards for newly developed Tests for twisted direction linings according to the present invention are currently being evaluated.
    Thus, the present invention relates to a multi-layer lining fabric comprising at least two warp-knit layers of at least one polymer thread material having a weight of > 100 g / m2 per layer of the material wherein the number of weft threads is greater than the number of warp threads, wherein - in the plane of the layers of the fabric - the direction of warp threads of a layer with respect to the direction of chain threads of an adjacent layer is twisted by an angle α of at least 20 degrees.

    The present invention also relates to clothing comprising the multi-layer lining fabric according to the present invention.
    Preferred embodiments of the clothing are claimed in the dependent of claim 9 claims.

    Preferred, but exemplary (and non-limiting) embodiments of the present invention, i. H. of the multilayer lining cloth and the garment of the present invention will now be explained in detail with reference to the figures.
    The term "comprising", "comprising" or "comprising" as used in the present specification and in the claims, for example in claim 1 (directed to the multi-layer lining fabric) or in the Description of the substance is defined as having the meaning that the substance according to the invention may include (or may include) (i) at least one component of the substance which includes the term "comprises" or "Comprising", or may include (ii) two or more components of the substance that include the term "comprising" or "comprising" or "comprising", or that (iii) other components (more particularly hereinafter referred to ¬niert) may also be included in the substance according to the invention. The same is applicable to the apparel claims and the description of the apparel of the present invention, mutatis mutandis.
    However, the term "comprising" or "comprising" or "comprising" as used in the present specification or claims is also defined for the present invention to include, where appropriate, cases in which the multilayer Feed material according to the invention mainly or even exclusively consists of (i) at least one component of the substance which follows the term "comprising" or "comprising" or "comprising", or mainly (or even exclusively) consists of (ii) two or more components of the substance which include the term "comprising" or "comprising" or "comprising", optionally together with any necessary component which may be additionally included in such substance by a skilled person in this technical field to solve the object of the invention or may even include cases in which the component of the substance containing the The term "comprising" or "comprising" or "comprising" follows, exclusively consists of (i) at least one specifically named component or exclusively consists of (ii) two or more specifically named components, if appropriate together with any necessary component which a person skilled in the art may include such substance in order to achieve the object of the invention. The same is applicable also to the garment-based claims and to the description of the garment of the present invention, mutatis mutandis.
    In other words, the term "comprising" or "comprising" or "comprising" in the context of the present description and within the scope of the claims means the meaning of describing or claiming an exhaustive or - alternatively - a non-exhaustive enumeration of Without excluding in the former case embodiments which, for example, in the subclaims of the present application and corresponding parts of the description claim (and describe) further features which are useful or advantageous, but not essential to the present invention.
    The present invention relates to a multilayer lining material. The term "lining material" as used in the present specification and claims is defined as meaning a textile material formed in the form of a plurality of layers, each of which consists of textile material threads. Such thread layers are produced in the context of the present invention by a chain-knitting method. As is generally known in this technical field, the method of Ket-ten knitting is a knitting method in which the thread zigzags along the length of the fabric and thus follows adjacent "pillars" of knitting, i. H. a knitting direction following the longitudinal direction of the knitted textile material. By way of example, this is shown in Figure 1, in which the arrow shows the direction of the warp thread. Such a textile material or cloth is used as lining under a surface layer or as a protective cloth layer (e.g., a garment) to produce a backsheet having special properties.
    In accordance with the present invention, the feed fabric is a multi-layer feed fabric, d. H. it has a number of layers of at least two. In accordance with the invention, at least two warp knitted fabric layers of a polyme¬ren thread material is included.
    The number of layers is not limited to two, and in preferred embodiments of the invention may comprise 2, 3, 4, 5, 6, 7, 8 or 9, or even more warp knit fabric layers. In the context of the present invention, there is no restriction with regard to the number of layers of the multilayer feed substance. One exception is the fact that a greater number of layers increase the total weight of the multilayer lining material according to the invention, this latter fact being in contrast to the object of providing a multi-layer lining material which is comfortable to wear Carrier of the fabric or clothing comprising the fabric increases, since the increase in weight of the substance makes movements in the sports or working environment of the wearer more difficult. A number of layers > 5 is more preferred, even more preferred is a number of 6, 7, 8 or 9 warp knitted fabric layers.
    The polymeric filament material may be a polymeric filament material that is identical in all layers of the multilayer feed fabric or may be two or more polymeric filament materials in different layers of the multilayer feed fabric. A person skilled in the art can choose such a single (or two or even more) polymeric filament material (s) from a large number of materials used in the art
    The prior art is known as such, in accordance with the specific requirements of a single case. In accordance with the invention, a single polymeric suture material is preferred for all layers of the multilayer lining material of the invention, but this does not limit the invention to this preferred embodiment.
    In accordance with the invention, the material of the (at least two) warp knitted fabric layer (s) is a polymeric filament material. Polymers for filaments that can be used to effect the warp knitted fabric layers of the present invention are well known to one skilled in the art and can be selected from a large number of polymeric materials in accordance with the requirements of a particular case Of course, one of these parameters is that the polymer must be able to process into threads suitable for the machine kneading process. Another criterion is the requirement that the material in the form of a thread must be able to be knit into a fabric material by means of a chain-knitting process.
    In accordance with the invention, the polymer material, after being knitted into a fabric layer, has a weight of > 100 g / m2. Polymer-material fabrics, which have a weight of > 100 g / m2, chain can be made into low-weight feed materials which have good mechanical properties, such as excellent drawability, light weight and good moisture-spreading properties.
    Basically, there is no upper limit to the weight of the polymeric material of the fabrics, except that it is to be claimed that in view of the task of providing a light weight material which enhances the comfort of the wearer, the material does not should have high weight. In preferred embodiments of the invention, which may be practiced alone or in combination with another feature or features of the invention, and which should not be construed to limit the invention, the materials used in each fabric layer , a weight in the range of 120 to 180 g / m 2, preferably in a range of 140 to 160 g / m 2, more preferably in a range of 160 ± 5 g / m 2. Exemplary (but nonlimiting) weights of the polymer material after it has been knit into a fabric layer are 132 g / m2 or 162 g / m2 or 114 g / m2 or 148 g / m2 or 171 g / m2, and such specific gravities may be used in combination with others, having advantageous properties for the invention. Materials having the above weight were found to be particularly suitable for the multilayer feed of the present invention.
    In further preferred embodiments of the invention, which may be practiced alone or in combination with another feature or some of the other features of the invention, and which should not be construed as limiting the invention, the materials have a thickness in the range of 0.4 to 1, 0 mm, preferably within a range of 0.6 to 0.8 mm, more preferably within a range of 0.65 to 0.75 mm, most preferably about 0.7 mm. Materials having the aforesaid thickness would be particularly suitable for the multilayer feedstock of the present invention.
    In preferred embodiments of the invention, which may be practiced alone or in combination with another feature or some of the other features of the invention, and which should not be construed as limiting the invention, the polymeric filament material is a polyester or polyamide , Polyesters are particularly preferred materials because they result in multi-layer lining fabrics that are comfortable to the wearer and, moreover, present good security properties, as shown in more detail below. One skilled in the art is familiar with polyesters and polyamides, particularly Polyesters familiar as polymer thread materials known in the art and can select such polyesters from a large number of such compounds in accordance with the requirements of a particular case. Even more preferably, the polymeric filament material may be a polyethylene terephthalate (PET). A particular material available on the market has been found to be a material which is particularly suitable, and this material is available from Engtex AB, Mullsjö, Sweden, under the trade designation "ENGTEX Dyneema".
    In accordance with the invention, the warp knitting of the fabric layers has been carried out in such a way that it results in a number of weft threads per cm length of the fabric layers being greater than the number of warp threads per cm width of the fabric layers. This numerical ratio represents the density of the action of the fabric-layer material.
    In preferred embodiments of the invention, which may be practiced alone or in combination with another feature or some of the other features of the invention, and which should not be construed as limiting the invention, in each layer, the number of warp threads 4 is 5 ± 0.5 threads per cm and / or the number of weft threads is 6.5 ± 0.5 threads per cm. Fabric layers of a polymeric filament material that has been warp-knit on fabrics having fabric densities in the above ranges exhibit particularly good improvements in their properties.
    In accordance with the present invention, the multi-layer lining fabric comprises at least two warp-knit layers of at least one polymer thread material, these layers being superimposed, and the number of warp-knitted fabric layers may be 2, 3, 4 , 5, 6, 7, 8 or 9, or even more warp-knit fabric layers, as mentioned above. In preferred embodiments of the invention, 2, 3, 4, 5, 6, 7, 8 or 9 or even more warp knitted fabric layers are stacked, and more preferably a number of 6, 7, 8 or 9 warp knit fabric layers, For example, 7, 8 or 9 warp knitted fabric layers, and most preferably 9 warp knitted fabric layers arranged one above the other.
    In preferred embodiments of the invention, which may be practiced alone or in combination with another feature or some of the other features of the invention, and which should not be construed as limiting the invention, the direction of the warp threads of a layer - in FIG Level of the layers of the fabric - twisted in view of the direction of the warp threads of an adjacent layer, and indeed by an angle α of at least 20 °. In other words, when two layers of a warp-knitted polymeric thread material are formed into a stack of two-filament material layers, they are not stacked on each other in a parallel direction (ie, with parallel chain-and-filament directions as in the prior art) Technique), but they are stacked in a twisted manner, so that their chain-thread directions are positioned at an angle α of at least 20 0. This is shown, for example, in FIG. 2: Two thread material layers 1, 2, each of them made by warp knitting, are shown juxtaposed in FIG. 2A, and they are in FIG. 2B in a superimposed arrangement and twisted in terms of their chain-thread directions (represented by darker lines) by an angle α of, for example, 80 °. The technical effect of a superimposed feature feature of the at least 2 (and preferably> 2) warp-knit yarn-material layers twisted by an angle α of at least 20 ° with respect to the directions of their warp yarns is two times: off From the viewpoint of "safety" is the blocking of the drive of a chain saw which cuts into the fabric provided with the multilayer lining fabric in a (for example) vertical or diagonal direction (the pant legs), in a shorter side region comparable to or even better than corresponding values of prior art clothing, however, the elasticity and stretchability of the multi-layered lining fabric (comprising the warp-knitted thread-material layers) is significantly increased. Even in multi-layer lining fabrics which have more than the minimum of two warp-knit fabric layers (eg> 5 or 6, 7, 8, 9 or more, for example 7, 8 or 9 warp knitted fabrics Thread-material layers), the comfort for the user (ins¬besondere due to the still increased elasticity and stretchability) is remarkable. Movement of the legs under high workload and thus including sweating of the wearer of the trousers provided with the multi-layered lining fabric is achievable without the occurrence of irritation on the skin of the wearer.
    In addition, in the case where a multi-layer lining cloth of the above type as in accordance with the present invention is fixed in chainsaw worker's pants and the pants are perpendicular to the standardized chain saw cutting test in direction and parallel to the pant legs (so-called PPE test or EU PSA type examination), the multi-layer lining fabric is able to block the operation of the chain saw better than in cases of pants of the prior art, which are provided with lining layers superimposed parallel to each other with respect to their twisted directions of the warp yarns of the plurality of layers. Details are described below in the experimental section.
    In preferred embodiments of the invention, which may be implemented alone or in combination with another feature or some of the other features of the invention, and which should not be considered as limiting the invention, the angle α is the twist in the direction of the warp threads one layer with respect to the direction of warp threads of an adjacent layer at most 120 °. When this upper limit of the twist angle α is taken into consideration, the elasticity and stretchability of the multilayer lining cloth is also increased. In multi-layer liners having more than the minimum of two warp-knit fabric layers (e.g., having 6, 7, or 8 layers of polymeric filament material, for example), the comfort to the user is (especially due to increased elasticity and stretchability) even better. Moving the legs under heavy workload and thus including a large amount of perspiration of the wearer in the pants provided with the multi-layered lining fabric is achievable without the occurrence of irritation or even inflammation on the skin of the wearer.
    In addition, the standard tests of these multilayer lining fabrics, which keep their twisting the direction of their warp threads below the upper limit mentioned above, lead to a better blocking of the operation of the chain saw by the threads of the multi-layer lining. substance.
    In more preferred embodiments of the invention, which can be implemented alone or in combination with another feature or some of the other features of the invention, and which should not be considered as limiting the invention, the angle α is the twist in the direction of the warp threads one layer with respect to the direction of warp threads of an adjacent layer within a range of 50 ° < α < 110 °. It is even more preferable in accordance with the present invention that the angle α of a twist of the direction of warp yarns of one layer with respect to the direction of warp yarns of an adjacent layer is within a range of 60 ° < α < 100 °. By keeping the twist angle in the above-mentioned preferred ranges, the above-mentioned characteristics of the wearing comfort and the chainsaw operation safety lock could be further improved as compared with the prior art.
    In further preferred embodiments of the invention, which can be implemented alone or in combination with another feature or some other features of the invention and which should not be considered as limiting the invention, the angle α is a twist of the direction of chain Threads of one layer with respect to the direction of warp threads of an adjacent layer within a range of 70 ° < α s 90 °. In most preferred embodiments, the angle α of twisting the direction of warp yarns of one layer with respect to the direction of warp yarns of an adjacent layer is within a range of 80 ° ± 5 °. Especially in the latter case, the elasticity and stretchability of the multi-layer lining material is increased to a surprising extent. In multi-layer lining materials which have more than the minimum number of two warp-knitted fabric layers (eg, 6, 7, 8 or 9 layers of the polymer thread material, for example), the comfort for the User (in particular due to the increased elasticity and stretchability) excellent, compared with the prior
    Technology. Moving the legs under heavy workload, and thus including heavy perspiration of the wearer in pants provided with the multi-layer lining fabric, is achievable without any irritation or even inflammation on the wearer's skin being observed.
    In addition, the standard tests of these multilayer lining materials, which keep the twisting of the directions of their warp threads in the range of 80 ° ± 5 °, led to a blockage of the operation of a chain saw by the threads of the multilayer lining. Lining material exceeding the values obtained with multilayer lining fabrics of the prior art having a relatively parallel arrangement of their direction of warp threads.
    In further preferred embodiments of the invention, which may be practiced alone or in combination with another feature or some of the other features of the invention, and which should not be construed as limiting the invention, the directions of warp yarns are particular layers of the multilayers Lining fabric M with respect to the direction of warp yarns of one of the lining layers as a reference layer to obtain angles α, a ', a " twisted, which are different from each other or which are identical to each other. In other words, in superimposed arrays of more than two (e.g., 5) filament material layers, all twist angles a, a ', a ", a " (etc.) of directions of the warp yarns of one layer with respect to the adjacent layer overlaid thereon are different from each other. The corresponding differences may be different in their absolute value of the angle (i.e., | a |), or may be different (or instead only) with respect to the clockwise or counterclockwise directions. As an alternative, all the warp directional angles α of different layers are identical to each other.
    FIG. 3 shows an example of the above-mentioned first case in which directions of warp yarns of certain layers of the multi-layer lining cloth M with respect to the direction of warp threads of one of the lining layers as a reference layer Angles α, α ', α " which are different from each other. In accordance with Figure 3, the angles α of twisting the direction of warp yarns change from one pair of layers (layers 1 -> 2) of filament material to the next pair of layers, i.e., the filaments. H. adjacent layers, layers 2 - > 3 - > 4, of filament material in their absolute values (eg α = 40 °, α '= 80 °, α = 60 °). In another preferred embodiment of the invention (which will be described below with reference to Figure 4), the twist angles α of another arrangement are identical in their (absolute) values but vary with respect to the clockwise and counterclockwise directions (e.g. B. α = 80 °, α '= - 80 °, α "= + 80 °). The above values are only exemplary values and do not limit the invention.
    In further preferred embodiments of the invention, which may be realized alone or in combination with another feature or some of the other features of the invention and which should not be construed as limiting the invention, the directions of the warp threads of two directly adjacent layers in relation to the direction of warp threads of one of the lining layers as a reference layer, twisted by the identical angle α (ie, | a | is always the same value), while the direction of chain threads is the following two adjacent layers are parallel to those of the reference layer, and the angles α are different "only" with respect to their clockwise or counterclockwise directions.
    This case is shown in Figure 4: the reference layer of the multilayer feed M has the reference numeral 1; Their direction of the warp threads is given by a darker line. The directly adjacent layer 2 of the multilayer lining fabric M has a direction of its warp threads (also represented by a darker line) which is twisted by the angle α with respect to the warp direction of the reference layer (1) , z. B. um80 0 ± 5 °. The layer 3 immediately adjacent to layer 2 of the multilayer feed M has a direction of its warp threads (also represented by a darker line) twisted by an angle α identical to the angle α between the layers 1 and 2 is in terms of its value but has a counterclockwise direction, e.g. B. - 80 0 ± 5 °. The same is true for layer 4, which is directly adjacent to layer 3 of the multilayer feed M described above; and so on. In other words, in the preferred embodiment of the multilayer lining material shown in Figure 4, the odd-numbered layers (e.g., 3, 5, etc.) each have directions of their warp threads (represented by darker lines while the layers having an even number (e.g., 2, 4, 6, etc.) are directions of their warp yarns (represented by FIG darker lines) which are at an angle value α of, for example, 80 ° ± 5 °, relative to the chain-thread directions of the odd-numbered layers (1,3, 5, etc.).
    In the latter case, a kind of "zigzag" arrangement of the relative twisting angle α of the respective adjacent layers is set for their relative directions of the warp threads. Such an arrangement is highly advantageous because the elasticity and stretchability of the multi-layer lining material are obtained to a surprising extent at a high level. In multi-layer liners having, for example, 6, 7, 8, or 9 layers of polymeric filament material, comfort to the user (especially due to increased elasticity and stretchability) is excellent compared to the prior art. Moving the legs under high workload and thus under the influence of heavy perspiration of the wearer in pants provided with the multi-layered lining fabric is achievable without irritation or even inflammation on the skin of the wearer being observed.
    In addition, the standard tests (according to the technical standards EN / DIN 381-2 and 381-5 for trousers for chainsaw workers) of these multi-layer lining fabrics, the twisting of the directions of their warp threads in the range of 80 0 ± 2 0 hold and the above "zigzag" configuration of their angles α of the chain-thread directions, relative to the chain-thread directions of the reference layer of the multilayer Futter-Stof¬fes, to block the operation the chain saw through the threads of the multilayer lining material, which itself exceeds the values obtained with multilayer lining fabrics of the prior art which have a relatively parallel arrangement of their directions of the chain threads; this was achieved in chainsaw cuts in a direction perpendicular to the trouser leg axis and even more in the direction parallel to the trouser leg axis.
    Further preferred embodiments of the invention, which may be practiced alone or in combination with another feature or some of the other features of the invention and which should not be construed as limiting the invention, are directed to multilayer lining fabrics according to the invention, in which 2, 3, 4, 5, 6, 7, 8 or 9 layers are layered one upon the other in an array with their directions of warp threads of adjacent layers of fabric twisted at an angle α of at least 20 ", and more preferably at most 120 0, and even more preferably within a range of 50 0 < α < 110 °, and the layers are loosely fastened together to form a loose fixed stack, that is, for example, loosely stitched, twisted layers.
    Such fixation of the lining-fabric layers, preferably by such stitching of the layers, may be effected preferably at the edges of these lining-fabric layers to form a loosely connected, flexible stack of these layers. Thus, in accordance with these preferred embodiments of the invention, such stacks of a plurality of loosely bonded / pinned fabric layers are intended to form flexible and stretchable "packs" comprising such a plurality of warp knit material layers and form substantially such "packs" where the relative position of the layers is not tightly fixed, but is loosely and flexibly connected. As a result, a substantial contribution to the desired flexibility of the feed substance can be made.
    The preferred way of loose fixation known to a person skilled in the art is lacing by loose stitching, although the invention is not limited to this type of loose fixation.
    In a further preferred embodiment of the invention, which can be realized alone or in combination with another feature or some other features of the invention and which should not be understood as limiting the invention, such a stack can be loosely fixed, z. Loosely sewn, twisted layers of lining material are enclosed in a textile pad, and such pad comprises a surrounding sleeve and an inner stack of 2, 3, 4, 5, 6, 7, 8 or 9 loosely fixed, z. B.locker sewn, fabric layers in one arrangement, a layer on top of the other, with their directions of the warp threads of adjacent fabric layers are rotated by an angle α of wenigs¬tens 20 0.
    The textile upholstery is defined as a textile fabric in sheet form for the present description and claims and is capable of forming the cover needed to encase the stack of fabric layers which is capable of accommodating this form of wrapping To maintain conditions of use of the pad and is able to be fixed by textile fixing processes such as sewing on other textile fabric materials. The material from which the pad is formed may be any material known to a person skilled in the art for the desired purpose of surrounding the plurality of loosely-sewn or loosely-sewn cloth layers, and such material may be any of those known in the art Persons skilled in the art are chosen from among a number of suitable materials according to the parameters that must be considered.

    EXAMPLES
    Pants for workers on chainsaws subjected to the tests described below included an outer waterproofing fabric made of ELASTAN® and an inner lining consisting of 8 warp-knitted fabric layers and an additional lining fabric made of LYCRA ® between the layers 7 and 8 (calculated from the inside to the outside of the lining-fabric stack (see Figures 5 A to 5 D)). In each layer, the number of warp threads was 4.5 ± 0 , 5 threads per cm, and the number of weft threads was 6.5 ± 0.5 threads per cm.
    The direction of warp threads of the warp-knitted fabric layer 2 was twisted by +80 ° with respect to the direction of the warp yarns of the layer 1; the direction of warp yarns of the warp-knitted fabric layer 3 was twisted with respect to the direction of the warp yarns of layer 2 by an angle of -80 ° (i.e., is the same as the direction of the warp yarns of layer 1); the direction of warp threads of the warp-knitted fabric layer 4 is twisted by +80 "with respect to the direction of the warp yarns of the layer 3; the direction of the warp-knitted fabric layer 5 is twisted by an angle of -80 ° with respect to the direction of warp threads of the layer 4 (i.e., is the same as the direction of warp yarns of the layer 1); etc., etc. This arrangement of the layers under the water-resistant fabric outer layer is shown by way of example in Fig. 5A.
    The 8 layers shown in Figure 5A were packed in a wrap made of ELASTAN® without sewing them together, and the surrounding wrap was stitched together at both ends. Any other assembly method instead of sewing could have been used.
    The resulting textile pad was applied to the left leg front of a chainsaw worker's work pants. The resultant pant has been evaluated by the wearers to provide the desired elasticity and stretchability and to not cause discomfort even under conditions of severe sweating.
    The same pants were tested the EU-PPE standard test by cutting on a test device with a chainsaw cut perpendicular to the trouser leg axis and stopped the chainsaw under conditions identical to those of the usual EU-PPE Standard tests were (speed of chain saws, cutting angle).
    In addition, the same pants were subjected to a modified test under the industry standard EN 381-2 and 381-5 and this standard has a test arrangement suitable for the multilayer lining fabrics due to their twisting of the warp-and-thread directions at the level of multilayer feed materials. Initial results (to be confirmed in further tests) showed that stopping the chainsaw chain by looping the chain with the warp threads is better than with conventional multi-layer liners having parallel directions of their warp threads. This surprisingly demonstrates a better adaptation to safety requirements for such types of garments and, in addition, better wearer comfort.
    Work pants made for workers on chainsaws of the above materials were subjected to a four week long field test at relatively high temperature (autumn) and high humidity (rain). Workers have found that these pants are better adapted to the requirements and more comfortable to wear under high sweaty conditions (mountain forests) than any other commercially available material. In particular, the desired elasticity and perspiration-wicking properties have been reported as exceptional. The invention has been described in detail above with reference to preferred embodiments thereof. However, reference to the preferred embodiments should not be taken as limiting the invention. On the contrary: the scope of the invention is determined only by the following claims.
