  • the method and product that is the subject of this disclosure begins with the formation of a bi- or multi-component yarn that will form the individual pile-like elements on the face of a pile or napped fabric.
  • a characteristic of the development disclosed herein is the use of component yarns containing yarns having significantly different shrinkage characteristics when exposed to similar shrinkage agents.
  • the pile or napped fabric may contain individual pile-like yarns that are comprised of two component yarns (e.g., the pile-like yarn is a bi-component yarn), in which the first such component yarn is of a type that exhibits a first type of shrinkage (e.g., relatively low shrinkage or relatively high melting point characteristics), and the second such component yarn is of a type that exhibits a second type of shrinkage different from the shrinkage of the first component yarn. (e.g., moderate or high shrinkage or low melting point characteristics, relative to the first component yarn type).
  • the yarns is textured.
  • the objective when using a two component yarn is to construct a pile-like yarn which, under the influence of selectively applied streams of heated air or some other means to induce shrinkage of the component fibers (e.g., chemical means, steam, etc.), will cause yarns of the second type to shrink more than yarns of the first type, to a degree that imparts a perceptible visual effect to the face of a fabric containing such pile-like yarns. If the component yarns initially are about the same length, component yarns having the second characteristic will selectively shrink below the level of the component yarns of the first type, thereby exposing more of the latter yarns and causing those yarns to become more observable.
  • some other means to induce shrinkage of the component fibers e.g., chemical means, steam, etc.
  • component yarns of the first type are dyed a different color or are otherwise visually distinguishable (e.g., have increased or decreased reflectivity) from those component yarns of the second type, then the color or other visual effect (e.g., reflectivity) associated with these more observable component yarns of the first type likewise will become more observable.
  • the component yarns used in the formation of the pile-like yarns may be either dyed or undyed prior to the fabric formation process, where the fabric is intended to have dyed pile-like yarns, generally at least one of the component yarns is dyed prior to the fabric formation process, and at least one is dyed following such fabric formation process.
  • this concept can be applied to pile-like yarns containing more than two component yarn types (i.e., multi-component yarns) in which at least one of the component yarn types has a shrinkage characteristic different from the other component yarn types. For example, if a pile-like yarn comprised of three component yarns, each having about the same length but each having a different shrinkage characteristic, is exposed to an appropriate shrinking agent (e.g., selectively applied heated air streams of the proper temperature), the various component yarns will each shrink to a different degree.
  • an appropriate shrinking agent e.g., selectively applied heated air streams of the proper temperature
  • each of the three component yarns is associated (either prior to or following the fabric formation process) with a different color or other visually distinguishing characteristic, a number of different complex visual effects may be generated, depending upon the visual characteristics associated with each of the respective component yarns (e.g., light vs. dark, complementary vs.
  • the angle of the incident light the angle of the applied heated air streams
  • the length and pile or nap density i.e., yarns per substrate unit area
  • the direction and uniformity of pile lay the nature and degree of reflectance associated with the various component yarns (which, in turn, may depend upon the composition, cross- sectional shape, surface smoothness, and color of the component yarns), the manner and extent to which the component yarns are length-wise coupled, and other factors.
  • two of the component yarn types could have similar shrinkage characteristics, thereby providing for situations in which those yarns comprise a majority component.
  • the minority component yarn type has relatively low shrinkage compared with the other component yarn types, it will provide a somewhat subtle visual contribution to the pile or napped face.
  • the minority component yarn type has relatively high shrinkage compared with other component yarn types, such shorter minority yarns will tend to recede into the pile or napped face and allow the visual contribution of the longer majority component yarns to dominate.
  • fabrics having a pile or nap comprised of four (or more) component yarns can be used, with the resulting visual effects having a potential for a correspondingly higher degree of subtlety and complexity. Accordingly, where the following discussions of techniques and process steps refer to pile-like yarns comprised of bi-component yarns, such discussions generally are also applicable to situations in which the pile-like yarns are comprised of multi- component yarns. As discussed above, in most embodiments, at least one of the component yarns is dyed prior to the fabric formation process.
  • yarns of at least one type may be different in length from other yarn types comprising the pile or nap even prior to the application of a shrinkage agent.
  • component yarns that are longer, but have a greater propensity to shrink may be made to shrink below the level of shorter component yarns that have a lesser propensity to shrink. If the initially longer yarns have greater reflectivity, the areas in which shrinkage does not occur will exhibit higher luster, shine, or iridescence than the areas in which the higher reflectivity fibers are shorter or partially hidden by the lower reflectivity component yarns that were initially shorter.
  • the higher-shrinkage component yarns were already shorter than other, relatively low shrinkage component yarns, the length differences between the two yarn types can be enhanced, causing the higher shrinkage yarns to recede further in the direction of the fabric base, with a corresponding increase in visual prominence of the lower shrinkage yarns and accentuation of the multi-level nature of the fabric.
  • Yarn 1 and Yarn 2 are component yarns that are used to construct a yarn used to form the face of a pile or napped fabric.
  • Yam 1 exhibits relatively low shrinkage (i.e., little reduction in yarn length), as compared with Yarn 2, when exposed to a shrinkage agent.
  • the shrinkage agent is heat
  • Yarn 1 preferably has a relatively high melting point or a lower shrinkage capacity (perhaps due to yarn pre-treatment such as package dyeing), as compared with Yarn 2
  • Yam 2 preferably has a relatively low melting point or a higher shrinkage capacity, as compared with Yarn 1.
  • Yarn 2 when exposed to the same shrinkage agent (e.g., heat) under similar conditions, Yarn 2 will shrink more than Yarn 1 to a visually significant degree.
  • Examples of possible fiber types that could be employed in the construction of Yarn 1 include low shrinkage heat set polyester, low shrinkage heat set nylon, or a low shrinkage cellulosic fiber such as rayon, acetate, or cotton.
  • Examples of possible fiber types that could be employed in the construction of Yarn 2 include low melting point polypropylene or high shrink polyester.
  • either Yarn 1 or Yarn 2 is textured.
  • Yarns 1 and 2 may be dyed by any means suitable for the nature of the constituent fibers.
  • yarns comprised of polypropylene, polyester, or nylon fibers may be solution dyed or package dyed, but the use of disperse, cationic, acid, direct, reactive, or VAT dyes is also contemplated, as will be apparent to those skilled in the art, depending upon the composition of the fibers to be used. If polypropylene is used and is intended to carry a color, it is recommended that it be solution dyed for best results.
  • Yarn 1 and Yarn 2 may be individually or collectively dyed or undyed, but if one or both are undyed, then preferably at least one of the undyed yarn(s) is capable of being dyed using conventional dyeing techniques following the fabric formation step. It should be noted that, in the case of package dyed yarns, such yarns characteristically have little propensity to shrink. Accordingly, it has been found that package dyed yarns are better candidates to serve as Yarn 1 (relatively low shrinkage) rather than as Yarn 2.
  • Yarn 3 indicated as optional at 1OC, depicts a situation in which a multi-component yarn comprised of Yarn 1, Yarn 2, and Yarn 3 is used to form the pile-like face.
  • Yarn 3 may be dyed or undyed.
  • the shrinkage characteristics of Yarn 3 most commonly will be different from either Yarn 1 or Yarn 2, i.e., it may be intermediate between the shrinkage characteristics of Yarns 1 and 2, or it may be even higher than that of
  • Yarn 3 may have a shrinkage characteristic that is substantially similar to either Yarn 1 or Yarn 2, or perhaps even less than that of Yarn 1, depending upon the nature of the visual effect to be achieved when a shrinkage agent is applied to the multi-component pile- like yarn.
  • additional yarns e.g., a fourth yarn, a fifth yarn, etc.
  • additional yarns may be used to form multi-component yarns from which the pile or napped fabric is constructed.
  • the shrinkage characteristics of such additional yams may be either similar or different from other yarns; the processing steps described herein apply regardless of the number of different component yarns used, except that separate dying steps may be necessary (depending upon the desired visual effect) following fabric formation if such yarns are undyed prior to the fabric formation process.
  • Step 20 of Figure IA represents the selected process by which the bi- or multi- component yarns that ultimately will form pile-like yarns are generated.
  • This process generally involves the length-wise coupling of two or more component fibers or yarns so that the component fibers or yarns can be treated as a single yarn during the fabric formation process.
  • This coupling may involve the formation of collaged yarns, parallel yarns, twisted or multi-ply textured yarns, or other types of yarns in which two or more individual component yarns are physically associated in a way that forms a bi- or multi-component yarn capable of serving as the pile-like yarns of a pile or napped fabric.
  • candidate processes include methods that result in the generation of a collaged yarn, such as air jet commingling, twisting, use of a stuffer box, etc. or methods used to form textured yarns such as crimping, false twist texturing, air jet texturing (a wet process), etc. It should be understood that the various component yarns can represent a mixture of different deniers, cross-sections, diameters, or the like.
  • the length-wise coupled bi- or multi-component yarn is used in a conventional pile or napped fabric formation process, indicated at Step 50 of Figure IA.
  • a pile or napped fabric formation process indicated at Step 50 of Figure IA.
  • the pile fabric may be formed in a double needle bar knitting machine, which forms a fabric "sandwich", in which the pile face is turned inward and spans opposing backing substrates. It should be noted that if the pile fabric is to be formed on a double needle bar knitting machine, then Yarn 1 and Yarn 2 can be combined by warping Yarn 1 and Yarn 2 individually, on separate beams, and threading an individual warp yarn from each beam through the same needle of the double needle bar knitting machine.
  • Steps 30 and 40 Individually optional processes that may be associated with the formation of the fabric having a pile-like face are indicated at Steps 30 and 40 - one or the other steps may be used, as necessary, depending upon the processes used in the fabric formation Step 50.
  • Step 30 indicates a conventional process commonly associated with the manufacture of, for example, double needle bar fabrics, in which the "sandwich” is slit or split in half, parallel to the plane of the fabric. This process step forms two pile fabrics, each having a pile height corresponding to half the distance that separated the opposing backing substrates.
  • Step 40 represents a process in which the loops are cut, thereby resulting in a fabric having a cut loop pile face, in which individual component yarns presumably are less constrained with respect to shrinkage. This can be achieved by napping, shearing, or any other process that effectively cuts the loops. If a loop pile fabric is to be used without such loop-cutting step, as shown in Figures 4A and 4B and discussed in connection with Example 9, then neither of Steps 30 or 40 is necessary.
  • the loops following the application of a shrinkage agent, tend to provide a coarsened or heathered appearance that may lack the definition possible with a cut pile face, but that may be aesthetically desirable for certain applications. However, it is anticipated that, in most cases, a cut pile fabric will be used due to the higher patterning definition possible.
  • the fabric optionally may be brushed and preferably lightly heat set at a relatively low temperature (one that will not affect shrinkage to any significant degree) and dimensioned to a standard width.
  • the fully formed, lightly heat set fabric that emerges from Step 60 is then ready to be visually enhanced by the application of shrinkage agents causing visible shrinkage of Yarn 2 (the relatively high shrinkage component yarn) relative to Yarn 1 (the relatively low shrinkage component yarn) in accordance with pattern data, indicated at Step 70.
  • this Step 70 could also be used, as desired, to cause pattern-wise shrinkage of other yarns (e.g., Yarn 3, Yarn 4, etc.) relative to Yarn 1.
  • the linear shrinkage of Yarn 1 will be less than about 10%, and preferably less than about 6%, and more preferably less than about 3%, while the linear shrinkage of Yarn 2 will be greater than about 12%, and preferably greater than about 15%, and more preferably greater than about 20%.
  • the shrinkage agent is heated air that is applied to the surface of the fabric.
  • other shrinkage agents such as application of a laser (see below), steam or the application of a liquid shrinkage agent, can be used if desired, so long as the effect is to induce relative shrinkage to one set of yarns (e.g., Yarn 2) without inducing the same linear shrinkage to a second set of yarns (e.g., Yam 1).
  • the application of the shrinkage agent of choice may be done uniformly if a uniform effect is desired, but, perhaps preferably in most applications, may be done selectively, in accordance with pattern information, either to establish a pattern on the fabric or to enhance an existing pattern (e.g., a dyed pattern) by inducing shrinkage of component yarns in registry with selected elements of such existing pattern.
  • pattern information e.g., pattern information
  • an existing pattern e.g., a dyed pattern
  • the temperature of the individually controllable streams of air, as they contact the surface of the fabric is sufficient to cause localized shrinkage or melting of the high shrinkage or low melting point component yarns comprising the pile-like surface, and to cause significantly less shrinkage to other component yarns comprising the pile-like surface.
  • This not only reduces the visual contribution of the shrunken component yarns in those treated areas, but, because the length of the component yarns have been reduced in such areas, the backing substrate may be less hidden by the pile-like surface, and may contribute to the overall visual effect of the fabric in those areas, depending upon the overall construction of the fabric.
  • melting points for the low shrinkage/high melting point component yams will lie within the range of about 460 0 F to about 750 0 F, and preferably between about 480 0 F and about 500 0 F, while melting points for the high shrinkage/low melting point component yarns will lie within the range of about 280 0 F to about 340 0 F, and preferably between about 300 0 F and about 320 0 F.
  • the pile-like face of the fabric prior to the application of the heated air streams, will have uniform pile lay and a relatively uniform color and appearance — the product of the combination of the colors of Yarn 1 and Yarn 2 as they are distributed over the fabric surface during the fabric formation process.
  • the heated air streams are applied selectively, in a pattern configuration, over the surface of the fabric. The effect is to induce selective shrinkage in the pattern areas of one type of component yarn (e.g., the "high shrinkage" Yarn 2), thereby making the visual contribution of another type of component yarn that is not shrunken to the same degree (e.g., Yam 1) more visually prominent.
  • Yarn 1 will now have more visual exposure, its visual characteristics such as color or reflectivity will tend to influence the overall appearance of the pile-like surface in those pattern areas. It is also contemplated that the heated air streams (or other shrinkage agent of choice) may be applied uniformly to the otherwise unpatterned pile-like surface, thereby generating a color formed primarily by the visual differences between component yarns that have been selectively shrunken and those that have not.
  • Step 70 of Figure IA can optionally be followed by a dyeing Step 80, in which the undyed component yarns, if any, forming the pile-like yarns are dyed.
  • this step may be performed using conventional jet dyeing techniques associated with a disperse dye cycle, in which the fabric is formed in a loop and circulated within a conventional jet dyeing apparatus.
  • the undyed component yarn is other than polyester, dyeing processes appropriate to that yarn type may be used.
  • Step 80 may consist of several sequential dyeing steps, perhaps one for each different type of component yarn, in order to achieve the desired effect. If no undyed component yarns are used to form the pile-like surface, Step 80 could be bypassed.
  • the pile-like surface can be selectively dyed in a pattern configuration following ⁇ or prior to — the selective application of the heated air streams.
  • selective dyeing it is recommended that such selective dyeing be carried out without causing appreciable shrinkage of the selectively dyed yarns (or at least shrinkage that is visually similar to that brought about by the selective application of the selected shrinkage agent , e.g., heated air streams).

  • the fabric emerging from Step 60 is dyed (e.g., in a dye jet) prior to being subjected to the pattern-wise shrinkage of Step 70.
  • the depicted process is one in which the process of Figure IB is extended, following the pattern-wise shrinkage step indicated at 70, to include Step 75, in which dye is selectively applied to the fabric.
  • This dye-generated pattern optionally can be in registry with the pattern already imparted to the fabric via Step 70, or can be in a pattern that is complementary to, or completely independent of, the pattern defined by the pile height differences brought about by Step 70.
  • the depicted process is that of Figure 1C with the omission of the initial dyeing step (Step 65 in Figure 1C).
  • the dye-generated pattern may be imparted in Step 75 in registry with the pattern imparted by Step 70, but need not be, depending upon the aesthetic effect desired.
  • the step imparting a pattern defined by pile height differences (achieved using, e.g., the selective application of heated air) and the step imparting a pattern defined by the selective application of dye (Steps 70 and 75, respectively, in Figure ID) are done in reverse order.
  • the pattern defined by pile height differences may be in registry with the dye-generated pattern, or, optionally, may be in a pattern that is complementary to or independent of the dye-generated pattern.
  • the nature of the visual effects obtained using the processes described above is dependent upon a variety of factors, including, importantly, the color of the component yarns, the configuration of the yarns in the tuft, the method of applying the shrinkage agent (e.g., if heated air, whether such air is applied to the face or back of the fabric, or both), and the relative length of the component yarns both before and after the application of a shrinkage agent.

  • the fabric yielded a two-color design, due to polypropylene and polyester having different colors. Due to commingling of these two fiber types, the color was determined by the extent of the shrinkage of the lower melting point fiber (e.g., the polypropylene), which, in turn, was controlled by the temperature of the heated air streams applied to the component yarns comprising the pile face of the fabric. Where little shrinkage of both fiber types occurred, the color was a blend of the colors of the respective fibers. Where the heated air streams caused significant shrinkage (due to melting) of the polypropylene yarns, with the polyester yarns being substantially unaffected, the color was predominantly that of the relatively exposed polyester yarns.

All processing steps were similar to those listed in Example 1, except the Millitex ® treatment values. Because the relative proportion of lower melting point polypropylene to higher melting point polyester in the pile face determines how much heat is required to create the patterns, the Millitex ® treatment values were as follows:
  • Results were essentially as recited in Example 1, except there were no objectionable streaks.
  • Example 3 The same starting yarns were used as in Example 1, but they were processed to form a pile fabric having pile tufts comprised of 2-ply Textured Package Dyed Polyester and 1-ply Cleartint ® Solution Dyed Polypropylene (Cleartint ® is a colorless polymeric colorant marketed by Milliken & Company, Spartanburg, SC). All processing steps were similar to those listed in Example 1, except the Millitex ® treatment used the following process values:

Abstract

Une nouvelle toile textile comprend des fils de type velours dans lesquels au moins un fil individuel est texturé, comprenant des fils de type velours individuels qui possèdent des caractéristiques de rétractation différentes et, un procédé de fabrication et de représentation de motif de ces toiles. Lors de l'application d'un agent de rétractation (par exemple des flux d'air chauffé), qu'ils soient appliqués de manière uniforme ou de manière sélective à la surface du velours, les fils individuels se rétractent selon des amplitudes différentes. Par la rétractation des fils à rétractation relativement élevée plus importante que celle de fils contigus à rétractations relativement faible, l'exposition visuelle des fils à rétractation relativement faible est accrue et, la contribution visuelle des qualités esthétiques (par exemple la couleur, la réflexion lumineuse, etc.) de ces fils à rétractations relativement faibles est renforcée.
