    [Technical field] [0001] This innovation concerns a recycled textile structure, in particular for woven shoe uppers.
    [State of the Prior Art] [0002] Thanks to advances in weaving and in the textile industries, all kinds of woven and / or weaving-related products are developing and are gradually being found in the life of all the weavers. days.
    Most woven products use only the necessary length of wire and dropped falls can not be reused for the most part. In recent years, with growing concern for environmental issues and the need to reduce pollution, recycling has become a critical issue. Therefore, it becomes essential to use the materials optimally and to recycle the weaving threads.
    [0004] On a fabric with colored patterns, the colors are distributed in a special way and the diameter of the threads is also particular. To overcome the difference in length, in general it is necessary to combine at least two son, mingle them and give them false twists. In this procedure, it is also necessary to add knots of cotton for adhesion, or to treat the ends of son by jets of air. If one wishes to go even further in the complication of the patterns (for example the number of colors), it is necessary to modify the twist of the thread, go through a dyeing step, or add additives to the original material , which is not feasible without increasing the cost price.
    In the light of the circumstances described above, the inventor of this innovation has spent years making painstaking research in order to create a recycled fabric for the uppers of shoes and to make improvements to existing technologies, in particular view of its implementation in the industry.
    [Description of the invention] [0006] In view of the problems mentioned above, the object of this invention is to propose a recycled fabric for shoe uppers, which can be produced in such a way as to contribute significantly to the reduction of pollution of the skin. environment and intelligently using resources.
    Thus, the invention proposes a textile structure comprising a plurality of woven or interwoven mixed yarns, in which each of the mixed yarns has a longitudinal arrangement and a plurality of first fibers and second interwoven fibers alternately, the first fibers of each mixed yarn constituting 30% to 50% of the total weight of the mixed yarn, and these first fibers being derived from a recycled fiber produced by the mechanical working of the fibers of a recovery mesh fabric., the mixed yarn forming a yarn unique and having differences in size and color distributed randomly, a portion of the first fibers acting as nodes of the single wire. This textile structure is largely a result of recycling and can itself be recycled.
    Optionally, a portion of the first fiber comprises a node.
    Optionally, the structure comprises nodes of random size, which can form the nodes of the mixed threads.
    Optionally, the structure has at least two colors. In particular, one of these colors may be on the vamp fabric.
    Optionally, the length of the first and second fibers is between 30 and 40 mm.
    Optionally, the mixed yarns have a density of 75 and 600 denier and / or comprise between 24 and 72 filaments.
    Optionally, the density of mixed son is 150 to 600 deniers.
    Optionally, at least one of the mixed son comprises between 6 and 20 fibers.
    Optionally, the structure contains at least one of natural cotton, polyester, nylon®, viscose, rayon or all of these materials.
    [0016] The innovation also relates to a mesh fabric for shoe uppers comprising a structure as described above.
    The innovation also relates to a shoe upper comprising such a structure.
    According to the previous description, the innovation provides a new fabric for shoe upper, including the recycled textile structure described above.
    According to the explanations above, the recycled textile structure and the shoe-vamped fabric described in this innovation, can have the following different advantages: [0020] 1) Short fibers can be spun to give a yarn unique whose diameter is random. In the case of a monofilament, and even if the diameter of it is very small, we can still achieve particular reasons.
    2) During the step of the working, the mesh fabric easily forms nodes or neps, and when twisting, the fiber will form slubs, and thus different sizes of nodes. Having no need to worry about the addition of knots, we can produce son of different diameters.
    3) This innovation allows the recycling of fabric scrap, especially unused pieces of mesh fabric and already tinted many colors, and give a natural thread random colors and patterns, without having to go through the dyeing fiber.
    [Description of Figures] Figure 1 shows schematically the recycled textile structure according to this innovation [0024] Figure 2 shows schematically the mixed threads shown in Figure 1 [0025] Figure 3 shows schematically the mixed threads shown in Figure 1 [ FIG. 4 schematizes the mixed wires shown in FIG. 1. FIG. 5 schematizes the mixed wires shown in FIG. 1. FIGS. 6A and 6B describe the procedure for using the recycled fiber structure.
    Figures 7A and 7B are schematic views of the recycled fabric structure according to a second embodiment of the present invention. [Embodiment] [0030] In the following, the embodiment of the recycled textile structure 1 will be described with reference to the appended figures, and for the sake of understanding, the same elements described in the embodiments will be designated by the same reference numbers.
    Figures 1 to 5 show schematically the first optimized way of this innovation for the use of the recycled textile structure. In the diagram, the recycled textile structure comprises woven or interwoven blend yarns. The mixed yarns 10 are composed of twisted ribbons 12 and when viewed more closely, these ribbons 12 are themselves uniformly composed of first fibers 14 and second fibers 16. The first fiber 14 is a recycled fiber. from the recovery mesh fabric that has undergone a process of processing. This first fiber 14 accounts for 30, 35, 40, 45 or 50% of the total volume of the mixed yarn 10. The latter is a single yarn, composed of a random distribution of fibers of different diameters and colors, and a part of this composition of raw fibers 14 give the knots 13 present in the single yarn. In the present embodiment, the blended wire 10 is wound on bobbins which are used to spin a flexible fabric, which is wrinkle-resistant, breathable, and of greater extensibility and elasticity.
    FIGS. 6A and 6B make a precise description of the first optimal use of this recycled textile and the steps of which are as follows: [0033] Step 100: The recovered mesh fabric is cut into lengths of 3 to 5 cm . The cutting is done on two lanes in order to facilitate the working procedure of the fibers that can be twisted. First, the mesh fabric falls are cut vertically 601 to form a warp and then in a horizontal direction 602 to form the weft and obtain a block, as in the diagram of Figure 6B. The size and manner of making the cut are not limited to what is described above, it can very well adapt the cut to the type of fabric. Mesh fabric falls may contain cotton, polyester, polyamide, nylon® or rayon. To be precise, the recycled fabrics used may be stitched fabrics of shoe uppers, and one can use at least two fabrics of different colors, whether printed patterns or digital dyes, or still mix mesh fabrics of different origins and colors. As a result, the final result does not require going through the dyeing step and can maintain a natural and random color.
    Step 200: Working, and cleaning. The cut fabric is subjected to mechanical fiber opening, mixing, and cleaning with a spindle bench to obtain a uniform ribbon. It is possible to mix any kind of fiber, that is to say it is possible to obtain a first fiber 14 of similar quality but of different nature and to mix with the second fiber 16 which can be synthetic for get that mixed layer of fiber. The working and cleaning of the fiber allows these mixed layers to be stretched, reducing the size of the fiber blocks or ribbons, and removing the impurities. In addition, depending on the nature of the yarn, its class and its various contents, the opening and cleaning can be done in different ways, automated or by hand, or both. Specifically, the working procedure of this innovation can be done from 1 to 3 times, and at most 5 to 7 times. The more the yarn is opened, the simpler is the separation, the losses of the mesh fabric can thus be reduced by 30 to 10%, and the procedure lengthens the fiber while making it more resistant to twisting. The opening of the fibers makes it possible to control their length following the procedure, for example by controlling the feeding, tearing and cutting. The optimal fiber length is between 30 and 40mm, for example about 30mm, 32mm, 34mm, 36mm, 38mm or 40mm. By using a transport wheel with high adhesion, the feed is stabilized and the length of the fiber can be controlled. In the process of defibrating the fabric, and as it was formed by knotting the yarns at the origin, the tearing occurring during the separation of the fibers can cause a friction which creates knots (knot of fibers). However, by managing to respect a length entering a predetermined frame, it is still possible to optimize the torsion of the fibers having nodes or neps by making sure, for example, that there are not more than 2 nodes or neps per fiber.
    Step 300: The combing step is necessary so that the ribbons or cotton layers are balanced, as well as to remove more impurities and short threads while maintaining its elasticity. The fiber mixture is thus put in place by constructing a cotton cloth, while making it uniform, and then tightening it into a thread that corresponds to the specificities of the ribbon 12, useful for the rest of the procedure.
    Step 400: The spinning. With the son 6, 8 and 12 (ribbons), we go to a doubling and stretching to produce stretched ribbons. In the course of the procedure, the mixed fibers are stretched straight and parallel to each other so that irregular thin strips can be spun into uniform strips, and the residues and dusts are removed again as shown in FIG. Figures 3 and 4.
    Step 500: The shaping is done following the creation of wicks by the operation of the ring spinning, which will stretch the fibers of the ribbon 12 (the ribbon) continuously and align them in a parallel manner, allowing the ribbon 12 to have an appropriate diameter by reducing the volume. The twisting is then continued to refine the yarn, to achieve the desired twist, and to obtain a strong blend yarn, which will then be wrapped around a spool of certain size and shape, as shown in FIG. to be extended from 10 to 25%, the strength of the fiber is between 20 and 40 cn / tex, and its density between 150 and 600D.
    Step 600: The weaving of the yarn can be done in different ways. The blended yarn 10 is woven or knitted to form the recycled fabric structure 1 of the present invention. The possible uses of this fabric are varied. It can be found in clothing, shoe uppers, gloves, hats and other accessories such as wallets.
    The application is done by recovering fabric falls, remnants of mesh fabric, and cutting them to the desired size. Then, these cut yarns are separated, cleaned, and again separated several times in order to give greater elasticity and to be able to mix the 14 and the second 16 raw fibers in a balanced way, to obtain a uniform thread ribbon or a uniform layer. Then, we proceed to the carding operation, in order to disentangle the ribbons and other layers of fibers, get rid of dirt, set up the mixture and obtain a uniform thread 12. Then, several ribbons 12 are mixed and stretched, they are twisted to obtain a uniform ribbon. Finally, a wicking operation is performed, followed by a ring spinning operation to obtain a hybrid wire having a suitable diameter and strength, which will then be wound on coils for easier handling. The recycled fabric structure 1 of the present invention can be prepared by weaving or knitting the blended yarn 10 obtained above. More specifically, it is possible to recycle scuffs of mesh fabric from vamp of already dyed shoes and of which the yarns are of denier density of 75, 150, 300 or 600D, which may contain between 24, 48 or 72 filaments, and this mixture makes it possible to obtain a recycled fabric with the different specificities described above with threads of different lengths. For example, a mixed yarn consisting of 6, 7, 8, 10, 11, 12, 15 or 20 filaments can be obtained. As a result, the knots or knots 13 of the blended yarn 10 are formed for the following reasons, (1) when twisted, the knots of the recycled fabric are covered, (2) when blended with the recycled knit fabric, fibers different specificities get entangled and lead to the creation of wires of different diameters. The mixed yarn 10 of the recycled textile structure 1 of the present invention has the same physical specificities as a piece of mixed yarn fabric 10 in the case of the same density (Denier) as the mixed yarn 10 of a textile banal and is suitable for making the shoe upper fabric. For example, if the blended wire 10 has a density between 150 and 600D, the fibers of a blended yarn fabric will have a strength of 20 to 40 cN / tex and a possibility of extension of 10 to 25% and the mixed yarn 10 of our recycled textile structure meets these same conditions.
    According to FIGS. 7A and 7B, the second possible optimization of the use of the recycled textile structure differs from the first application in the following ways: Two or more sets of mixed warp and weft yarns intersect transversely to form a fabric that is relatively strong, stable and gives more diverse patterns.
    According to the above description, the recycled textile structure 1 of this innovation, reuses falls of colorful mesh fabrics and thus, does not require a second color, becoming a natural and random color fabric. The pollution of the environment is therefore significantly reduced by recycling materials, and does not influence the particularity of the recycled fibers.
    The above description relates to non-limiting examples.
