    PROCESS AND APPARATUS FOR ANGULARLY SUEDING A TEXTILE WEB CONTAINING WARP AND FILL YARNS}
    [2] Spun yarns commonly used in the construction of nonwovens come in several forms. Among the most common known to those skilled in the art are ring spun yarns, open-end spun yarns (OES) yarns, air-jet spun yarns (AJS) and roller jet spuns (RJS). ; roller jet spun) yarn. Ring spun yarns consist of a generally spirally wound fiber that exhibits good feel and strength properties when woven into a fabric. As the twist level is increased with respect to the ring spun yarn, the fabric comprising them becomes stronger and rougher when the increased twist decreases fiber-to-fiber mobility. Compared to ring spun yarns, open-end yarns are more inorganic and have a lower twist. Fiber bundles comprising yarns are compacted by the presence of densely wound wrapper fibers that are approximately perpendicular to the axis of the yarns. When the yarn structure of the open-end yarn is less organic than the structure of the ring spun yarn, the open-end yarn exhibits a diameter larger than that of the equivalent denier ring spun. Due to the pressure imparted by the wrapper fibers, the larger size of the open-end yarn, which lacks the mobility of the fiber, results in a stronger fabric despite a lower twist compared to the ring spun yarn. In addition, tightly wound wrapper fibers cause the surface of the fabric to be rough and scratched upon touch. Relative fiber mobility makes it difficult to improve the fabric by needling with hydraulic jets because these yarns cannot be easily swollen when limited by wrapper fibers. In the same way, the wrapper fibers reduce the effect of pneumatic vibration softening as disclosed in Applicant's US Patent No. 4,918,795, which is incorporated herein by reference. When the wrapper fibers are not aligned with the axis of the yarns, these fibers do not contribute to fabric strength, and fabrics composed of yarns containing wrapper fibers are generally not as strong as fabrics composed of ring spun yarns. AJS and RJS yarns are similar to open-end yarns, but have core fibers with little or no twist, and the integrity of the yarn depends entirely on the presence of the wrapper fibers. Without fiber to fiber friction formed by the pressure exerted by the wrapper fibers, the yarns do not have tensile strength and are not woven into the fabric. Once the fabric is woven, yarn to yarn pressure is sufficient to create friction between the fibers, and wrapper fibers are no longer needed for strength. The fabric can be hydraulically repaired by dramatically improving the feel and surface feel of the fabric by loosening or cutting the wrapper fibers by various means such as sanding or fluffing to improve the feel and other properties without substantially cutting the load bearing fibers. In addition, it is possible not only to swell the fabric when needled or to soften it when vibrating with pneumatic pressure, but also to improve adhesion to the coating without compromising the fabric strength. Other methods of sanding and polishing fabrics are disclosed in US Pat. No. 5,058,329 to Love et al., Which is incorporated herein by reference, but from this without substantially reducing the strength of the fabric and without cutting the load bearing fibers therefrom. It is not effective in cutting or sufficiently loosening the wrapper fibers in the fabric in order to achieve the significant associated benefits that result.
    [3] While there is a possibility of cutting unloaded support wrapper fibers in yarn without substantially reducing the fabric tensile properties as disclosed in the US patent applications 08 / 738,787 and 08 / 995,184, which are incorporated herein by reference. It is often desirable to apply a suede finish by various forms of surface polishing, where the load bearing fibers are also cut. However, this method has some disadvantages.
    [4] One problem associated with this surface finish of the woven web is the potential to form stripes in the resulting fabric. There may be relatively brighter or darker lines appearing in the wrap direction. This is due to fabric or yarn irregularities, which can occur with random variations of grit properties. In particular, if larger or aggregated particles are present, more fibers will be cut and lighter colored fibers in the yarn core will be exposed to form streaks. One way to mitigate the effects of individual grit particles is to make very large abrasive drums so that the effects of single grit particles are not continuous. However, this method reduces the pressure of the fabric towards the treatment roll and requires some other means for generating pressure, such as using relatively coarse grit, flaps, back up rolls or air pressure. Another method is to oscillate the treatment roll along the axis of rotation to form streaks that are more difficult to find, thereby forming a sinusoidal pattern on the fabric, dispersing the effects of single grit particles. Such vibrations are often used in multi-roll processing machines and the vibrations must be timed so that they do not overlap.
    [5] Another common problem with all polishing methods is that cutting the fiber reduces the tensile properties of the fiber regardless of the yarn shape. Also, except in the case of wrap-cotton fabrics, the fibers of the fill yarn interact with the friction particles because they are more perpendicular to the movement of the abrasive particles when compared to the fibers of the wrap yarn. This interaction causes the peel yarn to lead to relatively greater abrasion and deterioration of strength, and to cause the peel yarn to move relative to the wrap yarn in the fabric. Putting these problems together, because of economical weaving reasons, many fabrics are easier to construct in the fill direction, and thus initially weaker in that direction. Fibers of wrap yarns, especially filament yarns, are more difficult to cut when in the parallel orientation of abrasive particles and filaments. Therefore, there is a need for a method of polishing the web so that the peel strength is maintained while the peel strength is maintained. The present invention solves these problems by a method of making a fabric which is significantly less flawed than by other methods previously used and not disclosed in the known prior art.
    [6] Summary of the Invention
    [7] Provided herein are methods and apparatus for providing improved and efficient suedeing and sanding of fill and wrap yarns through loosening, cutting, and polishing webs of fabric. The fabric web is oriented under tension around at least a pair of rotatable tubes (rolls) (approximately 2 to 24 inches in diameter) coated directly with the abrasive face and coated with abrasive particles disposed at a polishing angle. The axis of rotation of the roll is parallel to the plane of the web, while the polishing angle is a reduction of 90 ° in the counterclockwise direction the tube axis forms with respect to the web movement direction. If the roll axis is oriented in the conventional sueding direction and is perpendicular to the web direction, the polishing angle is 0 °. Preferred polishing angles for angled sueding are from about 5 ° to about 60 °, more preferably from about 10 ° to about 45 °. Preferably, rolls are used in pairs with each tube in a pair of positions at the same polishing angle. The polishing angle may be positive or negative and there may be more than one polishing angle if multiple pairs are used. The polishing angle is called the contact angle between the web and the roll, and is different from the wrap angle used in the related art. Preferred lap angles are 1 ° to 45 °, preferably about 2 ° to 30 °.
    [8] The rolls are in pairs, one of which is a retracting roll and the other of which is a forward roll. Retracted means that the rolls have elements that rotate in a direction opposite the direction of web movement to increase the resulting tension of the web. Advancing means that the rolls have elements that rotate in the same direction as the web travel direction at surface speeds faster than the web speed, thereby reducing the resulting tension of the web. The tension of the fabric should be at least 2 pounds (p.l.i.) per inch of web width.
    [9] It is therefore a primary object of the present invention to provide a more balanced polishing treatment of wrap and fill yarns. Another object of the present invention is to provide sueding at a higher level with the peel tension and tear properties maintained the same. Another object of the present invention is to provide a method of cutting fibers of a filament wrap yarn. It is a further object of the present invention to provide an apparatus for suing a web at an angle. It is another object of the present invention to provide a sueding method that is essentially free of stripes. Another object of the present invention is to provide a method of sueding fabrics sensitive to the movement of the fill yarn.
    [10] Other objects and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings, in which embodiments of the invention are disclosed by way of illustration and example.
    [1] FIELD OF THE INVENTION The present invention generally relates to the field of cotton processing, and in particular, to a method and apparatus for angled suede fabric webs comprising fill and wrap yarns. More specifically, the present invention relates to a method for angled polishing of a web of fabric to form efficient and improved sueding in the web and to reduce the likelihood of significant defects in the final fabric. Also provided is an apparatus for carrying out this.
    [11] The above and other objects of the present invention will become more apparent upon reading the following detailed description of preferred embodiments of the present invention with reference to the accompanying drawings.
    [12] 1A is a plan view of a cross section of a woven web comprising a filament yarn to be treated,
    [13] 1b is a plan view of a cross section of a woven web comprising a filament yarn to be treated,
    [14] Figure 2 is a right side view of the preferred embodiment of the present invention shown in Figure 3,
    [15] 3 is a front view of a preferred embodiment of the present invention.
    [16] The drawings form a part of this specification and include exemplary embodiments of the invention that can be embodied in various forms. In some instances, various embodiments of the invention may be understood to be exaggerated or enlarged to aid in understanding the invention. The specific details disclosed herein are not intended to be limiting, but rather to those skilled in the art to practice the invention as a basis of the claims and ultimately in all suitably described systems, structures or methods. The state should be interpreted as a representative basis.
    [17] Referring now to FIG. 1A, the direction 42 indicates the orientation of the filament yarn 13a of the fabric web 11a and the filament fill yarn 15a is perpendicular to the direction 42. When the fabric or web 11a passes over a treatment roll (rolls 16, 20, 24, 28 shown in FIG. 2), the particles of abrasive grits (not shown) are selectable, which can be referred to as the polishing direction. In contact with the fabric 11a. The polishing direction is bidirectional depending on the rotational direction of the processing roll. If the roll is rotated at high speed in the same direction as the fabric so that the fabric is polished in direction 42, the polishing direction is 0 degrees. Next, if the same roll is rotated toward the fabric, the polishing direction is 180 degrees. If the polishing direction is aligned with the wrap yarns 13a in the direction 42, the fibers in the fill yarns 15a are preferred when these fibers are oriented perpendicular to the polishing direction and more easily bonded to the polishing grit (not shown). To be cut. Grit particles (not shown) tend to slip without being cut between fibers oriented along the direction 42. If the abrasive particles move in the direction 40 or direction 44, both the fill fiber and the wrap fiber are cut. Next, since both the wrap fiber and the peel fiber contribute to the surface aesthetics, the treatment level can be reduced while maintaining the same sensed treatment level. Thus, the retained length of the fill yarn of the fabric becomes larger than when the fabric is treated in the direction 42. The relative angle measured counterclockwise from the direction 42 to the polishing direction is defined herein as the polishing angle, preferably between 5 ° and 60 ° or between -5 ° and -60 °, most preferably about 10 degrees to about 20 degrees or about -10 degrees to about -20 degrees. Since the polishing direction is bidirectional, the polishing angle is defined to be 180 ° in the same manner as the polishing direction.
    [18] In FIG. 1B, both the wrap yarn 13b and the fill yarn 15b are Z-twist ring spun yarns. Although the fabric is ground in the direction 42 to cut the fabric in both the fill and wrap directions, it is common for damage to the fill yarn to be shown in the plain weave fabric shown because the yarn's helical angle is generally less than 45 °. . If the helical angle is 0 °, the yarn is one of several forms of a filament yarn as shown in FIG. 1A or a spun yarn such as air jet spun (AJS) or roller jet spun (RJS), the spun yarn being a yarn fabric Is almost zero in thickness. Ring spun and open-end (OE) yarns exhibit a spiral angle as shown in FIG. 1B, which contains wrapper fibers that do not contribute to the strength of the fabric. In the case of a ring or open-end yarn with a Z-twist, the strength of the fill yarn 15b is actually reduced to a greater than the same polishing level in the direction 42 by polishing the fabric along the direction 40, while Polishing the fabric in the direction 44 reduces damage to the fill yarns. In order to reduce the abrasive damage of the fill yarn with Z-twist to an absolute minimum, the fabric must be treated in a direction 46 parallel to the fibers constituting the fill yarn 15b. The direction used for fill yarns with S-twist is the same as the direction used for fill yarns with Z-twist. Thus, in order to reduce the abrasive damage to fill the yarn with S-twist, the fabric should generally be treated in direction 40, and in order to reduce the peel damage to an absolute minimum, the fabric would be parallel to the spiral angle of the fill yarn. Should be treated in the direction of
    [19] The 6 oz./square yard poplin shirting fabric is processed along direction 40 (-15 °), direction 42 (0 °) and direction 44 (15 °). Both wrap yarns and fill yarns are Z-twist, open-end yarns having a spiral angle of approximately 30 ° and intimately kneaded with 65% polyester and 35% cotton fibers. The web speed is 22ypm, the web width is 60 inches, the web tension is 5 pounds per inch of web width, and the treatment roll diameter is 3 inches. A pair of treatment rolls covered with 30 grit SiC paper is used. The first treatment roll is reversed and rotated towards the fabric at an absolute relative surface speed of 9.3 times the speed of the fabric. The second treatment roll is reversed and rotated towards the fabric at a relative surface speed of 7.3 times the speed of the fabric. For untreated fabrics, the fabric strength in the fill direction is 75 pounds / inch. After grinding in direction 42, the strength drops to 32 pounds / inch. As the fabric is polished in the direction 40, the peel strength drops further to 30 pounds / inch. When the fabric is polished in the direction 44, the retained peel strength is substantially higher at 42 pounds / inch. The aesthetics of the three processed samples are not detectable.
    [20] FIG. 2 is for angled suede fabric web 11 comprising wrap and fill yarns, inlet and outlet means (not shown), tensioning means (not shown), inlet and outlet means ( Two pairs of treatment rolls 16, 20, and 24 and 28 disposed between each other, and web engaging means 18 and 26 disposed between the pairs of treatment rolls 16, 20, and 24 and 28, respectively. Is shown. Tension means (not shown) include a load cell (not shown) for measuring the tension of the fabric web 11, an electronic control system (not shown), a drive roll 12 and an inlet for substantially tensioning the fabric. Drive roll 14; The fabric web 11 is continuously fed onto the inlet roll 12 to an optimally submerged bath contained in the tray 34 and via tungsten carbide bites through three different rollers 48, 50 and 52. It is supplied to an applied inlet drive roll 14 to provide a high friction surface. The inlet drive roll 14 is driven by a motor and a gearbox (not shown). Next, the web 11 is lowered through a pivotable subassembly comprising treatment rollers 16, 20 and a slidable engagement roller 18 operated by an air cylinder (not shown). As shown, the engagement roller 18 is retracted to allow the fabric web 11 to pass through the treatment rolls 16 and 20 without being in contact with the treatment roll 18 in the case where it is desirable to bypass the treatment zone. do. The fabric is fed around a roll 22 with a load cell (not shown) for monitoring web tension. Optionally, roll 22 may be a metered dancer roll.
    [21] The web 11 then enters a second subassembly comprising treatment rolls 24 and 28 and engagement rolls 26. This engagement roll is shown extending to form a wrap angle around the rolls 24, 28. All treatment rolls are driven by individual motors and drive belts (not shown). The treatment rolls 16, 20, 24, 28 can be driven in all directions but balance the lateral load on the web to prevent the web from driving to one side and reduce the tendency for longitudinal wrinkles to form in the web. In order to do this, the treatment roll is preferably driven in the opposite direction. The web 11 is moved upwards to the same exit drive roll 30 as the inlet drive roll 14, wound around the roll 54, and then moved to a web take-up roll (not shown).
    [22] 3 shows a first pivotable subassembly comprising treatment rolls 16, 20 and engagement roll 18, and a second pivotable subassembly comprising treatment rolls 24, 28 and engagement roll 26. By showing the orientation, all treatment rolls are advantageous for webs comprising yarns with S-twist to polish the bottom face of the web 11 at an angle corresponding to the direction 40 of FIG. 1B. In addition, two pairs of treatment rolls are oriented at two different angles so that the treatment can be performed in two different polishing directions. For example, if one subassembly is oriented to be polished along the direction 40 and the second subassembly is oriented to be polished along the direction 44, cross polishing of the web is achieved, especially with low or no twists. It is advantageous for webs containing yarns. Particularly for webs containing fibers that are difficult to cut, it may sometimes be useful to orient the first pivotable subassembly to an incineration to partially cut the fiber and then to treat it at a large angle to the next subassembly. More than one pass may be made and the apparatus may be configured to have only one or multiple pairs of treatment rolls.
    [23] The lateral movement of the web during the treatment is partially eliminated by the proximal position of the counterrotating treatment rolls 16, 20 and 24, 28, and the pair of first rolls, such as the rolls 24 and 26, are retracted, ie the fabric web. While rotated in a direction opposite to the direction of 11, a pair of second rolls, such as rolls 28 and 20, advances, ie rotates in the same direction as the web 11. These rolls 16, 20 and 24, 28 are preferably spaced at intervals no greater than 24 inches between the rolled surfaces, and more preferably these rolls are spaced at intervals no greater than 12 inches. The treatment rolls 16, 20 and 24, 28 may be surrounded by paper or cloth coated abrasives or may be spray coated with metal carbide grit, such as tungsten carbide with a roughness in the range of 50 to 400 US cavity grit, preferably Diamond grit is coated in an electroplated metal matrix with grit sizes ranging from 50 to 800 US cavity grit. Useful polishing angles are typically between 5 ° and 60 ° and between -5 ° and -60 °, preferably between about 10 ° and 45 ° and between -10 ° and -45 °. In addition, the lateral motion is controlled by the tension applied to the web, the tension being at least 1 pound per inch of web width, preferably at least 2 pounds per inch of web width, and can be considered the final tensile strength in the wrap direction 42. It should be less than 50% of the breaking strength. Preferably, the diameters of the treatment rolls 16, 20 and 24, 28 are 1.5 to 24 inches, most preferably 2 to 12 inches. The absolute value of the surface speed of the treatment roll is the surface of the fabric web divided by the cosine of the polishing angle in order to avoid the possibility of sticking-slip engagement of the fabric web 11 with the fabric being able to run sideways to form wrinkles. It should be at least 1.5 times the speed.
    [24] Angular polishing is inherently free, since the tracks of polishing caused by the individual grit particles lie on the polishing angle and cannot overlap on themselves, forming a significant stripe in the wrap direction 42. In addition, the resistance of the fill yarns due to engagement with the grit particles is induced by the polishing angle so that the movement of the fill is similarly reduced.
    [25] Angular polishing may be advantageously used on other substrates in addition to those described above. For example, the fabric web may comprise a filament wrap in combination with a spun fill, or the spun wrap may be combined with a filament fill.
    [26] Although nonwovens containing wrap and fill yarns have been described, nonwoven webs containing fibers of random orientation may be advantageous from angular treatment, especially when cross-sueding is used. In this case, the fibers predominantly lying in the direction 42 can be cut in addition to the fibers in the other direction in a manner similar to the cutting of the fibers in the filament wrap yarn 13a.

To cover.
