Definitions

  • This invention relates to the preparation and utilization of wrapped elastic yarns. More particularly, it relates to improvements in the art of making and utilizing wrapped elastic yarns including a transient stretch-limiting member and to fabrics manufactured therefrom.
  • the inelastic core member may be of a type that may be subsequently dissolved out, or it may be a member that Will withstand the stresses of weaving but is frangible enough to rupture when extra stress is applied after the yarn has been converted into a fabric.
  • Such an inelastic member is designated herein as a transient strand, and potentially elastic yarns restrained by the presence of such a strand are said to be transiently stabilized.
  • an elastic core member with -a second core member that is inelastic but retractable.
  • an elastic -core member I mean a strand or set of strands which readily extend to several hundred percent, with relatively rapid recovery, such as rubber yarns, spandex yarns, and the like, widely-known and usedin the garment and elastic stocking industries.
  • an inelastic retractable core member I mean a strand or set of strands which when suitably treated will shrink substantially in length, but which will withstand the normal stresses and tensions of weaving or knitting Without showing substantial elongation. This retractable inelastic strand must be removable from the fabric by appropriate treatment when the restraint it affords against elongation becomes undesirable.
  • a further object is to provide a process for transiently stabilizing a potentially elastic wrapped composite yarn wherein the elastic yarn element is adhesively united to the wrapping element, and the product of said process.
  • Still a further object is to provide a process for making a transiently stabilized potentially elastic yarn in which the elastic element is in a state of compression.
  • Another object is to provide methods for the preparation of elastic fabrics of novel properties.
  • the steps involved in the process of this invention comprise: Y
  • the composite yarn is allowed to relax to a desired degree of extension, thus deforming the inelastic core strand into a waved or convoluted configuration.
  • the convoluted retractable core strand is treated to shrink it down to a length which matches the length of the elastic strand, whereby the convoluted surplusage of the retractable strand is eliminated and said strand stabilizes the composite yarn against further elongation.
  • the composite yarn is treated so as to cause the inelastic retractable strand to retract to a desired degree, whereby the elastic yarn is deformed into a waved or convoluted configuration: that is, there is a built-in surplusage of elastic strand, parts of which may be presumed to be under longitudinal compression.
  • the composite yarn is stabilized against extension by the set condition of the retracted inelastic core strand.
  • the stabilizing inelastic core strand is dissolved, ruptured, or otherwise rendered ineffective, whereby the elastic properties of the fabric are developed.
  • FIGURE 1 is a fragmentary side elevation of the assembled elements of a yarn useful in the practice of this invention, a single wrapping strand only being shown for clarity.
  • FIGURE 2 is a representation of the composite yarn of greases FIGURE 1 after relaxation of the elastic core strand, said elastic core strand having been wrapped while extended.
  • FIGURE 3 is a representation of the composite yarn of FIGURE 2 after the transient core member has been caused to retract.
  • FIGURE 4 is the composite yarn of FIGURE 1 after shrinkage of the inelastic core strand, the elastic core strand having been wrapped under little or no extension.
  • FIGURE 5 is the yarn of FIGURES 3 or 4 after removal of the transient core member.
  • FIGURES 6 through 10 represent another embodiment of the invention wherein an elastic core member, a retractable transient core member, and an inelastic permanent stay member are combined into a composite wrapped yarn.
  • FIGURES 11, 12, 13 and 14 are comparable to FIG- URES 1, 2, 3, and 5 respectively, except that the wrapping strand is disposed around the composite yarn in a different manner.
  • the elastic strand 11 is considered to be under extension when it is combined with the inelastic retractable strand 12 in the wrapping operation.
  • the inelastic core member 12 is also capable of retraction, which may be effected by heat, moisture, chemical sensitivity, or other mechanisms known in the art.
  • FIGURES 3 and 13 show the yarns of FIGURES 2 and 12, resectively, after a retracting process has been carried out on the inelastic core member 12 in both cases.
  • the convoluted conformation of the strand 12 of FIGURES 2 and 12 has given way to a smooth configuration, the elastic and the inelastic core members are of substantially equal length, and the composite yarn is stabilized against elongation by the re tracted configuration of the strand 12.
  • FIGURES 5 and 14 represent the yarns of FIGURES 3 and 13 after the restraining strand 12 has been dissolved out, with the resultant yarn free to elongate.
  • FIGURES 6 through 10 represent another modification of the process of this invention where it is desired to produce a wrapped elastic yarn that can be stabilized against extension in the weaving or knitting process, as above, but which will be of limited elongation after the transient restraining yarn is removed.
  • FIGURE 6 shows an elastic core strand 10, a retractable inelastic transient strand 12, and a permanent inelastic strand 18, the function of which may best be described by calling it a stay strand.
  • the three-member core is wrapped conventionally, only one wrapping strand 14 being shown for the sake of clarity.
  • the elastic core strand 10 is under extension when being wrapped in FIGURE 6.
  • both the transient retractable yarn 12 and the permanent stay yarn are buckled.
  • FIGURE 9 represents the yarn of FIGURE 7 after removal of the transient restraining yarn 12, and FIGURE 10 is the yarn of FIGURE 9 under tension.
  • the yarns of FIGURES 5 and 14 are capable of elongation up to the elastic limit of the elastic core 10, or to the point at which the wrapping strand 14 exerts a limiting influence
  • the yarn of FIG- URE 9 is limited in extension to the original length at which the elastic core yarn 10 and the permanent stay yarn 18 were combined together, beyond which point the relatively inelastic stay yarn 18 cannot be stretched.
  • the practise of this modification of the invention will be found particularly advantageous in the fabrication of certain garments or elastic supporting members therefor, where in 1t is desired to realize an elastic material with lowmodulus of elongation and limited stretch.
  • the low modulus of elongation is provided by converting theyarn into a fabric while the elastic core is under little or no extension, say at extensions of or less: the. limited stretch is provided by the stay yarn 18.
  • the elastic core yarn 169 in this invention is conveniently a natural or synthetic rubber yarn, or a yarn of a segmented polyurethane type known generically as a spandex yarn, one type of which is Lycra yarn made by E. I.v du Pont.
  • the wrapping yarn may be any desired yarn which is not adversely affected by the retraction process to which the transient core strand 12 is subjected, as set.
  • the stay strand 18 may also be of almost any desired nature: a yarn of continuous filament nylon is quite satisfactory.
  • retractable transient core strand I may use a yarn of polyvinyl alcohol filaments, generically known as vinal.
  • polyvinyl alcohol yarns as scaifolding yarns, due to their water solubility, much as calcium alginate yarns are used and later dissolved in alkaline solutions.
  • I am aware it has not been known to carry out an intermediate retraction process on the polyvinyl alcohol yarn to diminish its length.
  • polyvinyl alcohol yarns and calcium alginate yarns have been treated as equivalents in the transient yarn art, whereas in the process of this invention I find polyvinyl alcohol yarns eminently suitable and calcium alginate yarns quite unsuitable, due to the fact that the latter yarn cannot be readily retracted by any process with which I am familiar.
  • the degree of retraction potential in the transient retractable yarn should be of the order of 40% or 50%, although such degrees of retraction need not always be utilized. That is, if an elastic core strand is extended 300%, to four times its original length, and is combined with a polyvinyl alcohol filament strand by a wrapping operation, a subsequent 50% retraction of the polyvinyl alcohol strand will stabilize the composite yarn at a point where the elastic core strand is extended 100%, or to twice its original length.
  • Retraction of a polyvinyl alcohol transient core strand may be readily efiected by the use of moisture. As in the case of most reactions involving wetting, swelling, and the release of inherent contractile strains, this is a timeatemperature dependent reaction.
  • a 420 denier spandex core strand was extended 300%, combined with a 300 denier polyvinyl alcohol core strand, and wrapped with two strands of 75 denier 30 filament viscose yarn according to the method described in U.S. Patent 3,078,654.
  • a length of this composite yarn was dropped into water at 20 C., retraction was quite sluggish, taking about 5 minutes for completion. At 35 C. the retraction was complete in about 30 seconds: at 50 C., retraction was practically instantaneous.
  • the process should be conducted so that the polyvinyl alcohol strand is (1) retracted, and (2) rendered adhesive, but (3) not heated to the point of complete gelatinization, strength loss, or dissolution.
  • immersing a composite yarn of this type in water heated to 50 or 60 C., for one or two seconds, followed by drying on a revolving drum heated with low-pressure steam will serve to stabilize the composite yarn with an accompanying fusion of the transient polyvinyl alcohol core strand with the wrapping strand and the elastomeric core strand.
  • fusion of this type is particularly advantageous when the elastomeric core strand has a strong tendency to retract spontaneously: that is, when it has been wrapped under considerable extension, so that the elastic modulus is high. If the elastic core strand has been elongated only or to twice its unextended length in the wrapping process, and it is desired to stabilize this yarn at an elongation of 50% by retracting the transient retractable core strand, then the mere contact and presence of the retracted transient core strand may serve to stabilize the composite yarn in this low-modulus portion of the elongation curve, without the development of adhesive union between wrapping strand and elastomeric core strand.
  • transient retractable core strands include materials which retract by heat alone, without the use of water, such as Vinyon, a product of Union Carbide and Carbon Corporation. Although the normal cellulose acetate yarns of commerce are not heat-retractable, they do become so when plasticized by the inclusion of 30 parts or more of plasticizer per 100 parts of cellulose acetate. In the case of both Vinyon and plasticized acetate, a retractable transient core strand made of these materials may be both retracted and rendered adhesive under the influence of heat, the Vinyon requiring lower temperatures than the plasticized acetate.
  • the stabilizing influence of the transient yarn may be rendered ineffectual by methods known in the art: that is, by exposing the fabric to stresses sufiicient to rupture the transient strand, or more satisfactorily by dissolving out the transient strand.
  • a transient polyvinyl alcohol strand this may readily be done by boiling thefabric in Water. Both Vinyon and plasticized acetate may be dissolved out by the use of acetone.
  • Other mthods of practising the invention will readily occur to those skilled in the art.
  • a particular advantage of composite yarns stabilized by the retraction of a transient core member, in accordance with this invention, is that the stabilization may be made exact and absolute by, a simple tension adjustment in the retraction process. It should be recognized that it is difiicult to stabilize a composite elastic core-transient core assembly by conventional wrapping methods, since the retractive tendency of the elastic core tends to override the stabilizing influence of the transient core. Multiple conventional wrappings are usually necessary, andthe prior art methods completely fail to stabilize composite wrapped yarns made according to U.S. Patents 3,078,654 or 3,011,302.
  • a supply of yarn was prepared by combining a 420 denier spandex core strand and a 300 denier 12 filament polyvinyl alcohol core strand which were wrapped with two strands of 75 denier 30 filament viscose yarn according to the process of US. Patent 3,078,654.
  • the spandex core strand was extended 300%, or to four times its original length.
  • the composite yarn was allowed to relax completely.
  • a ten inch length of the relaxed yarn could be readily extended to 30 inches, or 200%. It will be appreciated that this inch length of yarn represented only 7 /2 inches of original spandex core strand, extended 33% to 10 inches and held there by the nature of wrapping.
  • the relaxed stable yarn of this type was elongated 200% and held at that elongation while it was treated with water at 60 C. and then was immediately dried by a drum heated by low pressure steam.
  • the resulting product was a stable inelastic yarn containing a spandex core strand stabilized at 200% elongation from its wrapped length.
