Definitions

  • the present invention relates generally to a method for providing one or more types of coatings on a fiber or yarn to enhance the properties of the fiber or yarn, and/or protect the fiber or yarn from infiltration by contaminants, and the coated fibers or yarns produced therefrom.
  • one object of the present invention is to provide a method for coating a yarn component, or plurality of yarn components individually or assembled into a single unit, with a (co)polymer that is environmentally friendly, and efficient.
  • a further object of the present invention is to provide a method for coating a yarn component, or plurality of yarn components individually or assembled into a single unit, that can also color the yarn component simultaneously and uniformly.
  • a further object of the present invention is to provide a method for coating a composite yarn with a (co)polymer to improve processing and durability of the resulting coated product, as well as prevent infiltration of contaminants into the body of the resulting coated yarn product.
  • a further object of the present invention is to provide a coated yarn product prepared by the method of the present invention.
  • Fig. 1 represents a preferred embodiment of the process of the present invention, wherein one or more yarn components (13) are passed through a treatment bath (11) in which is contained a treatment composition.
  • fiber refers to a fundamental component used in the assembly of yarns and fabrics. Generally, a fiber is a component which has a length dimension which is much greater than its diameter or width. This term includes ribbon, strip, staple, and other forms of chopped, cut or discontinuous fiber and the like having a regular or irregular cross section. “Fiber” also includes a plurality of any one of the above or a combination of the above.
  • high performance fiber means that class of synthetic or natural non-glass fibers having high values of tenacity greater than 10 g/denier, such that they lend themselves for applications where high abrasion and/or cut resistance is important.
  • high performance fibers typically have a very high degree of molecular orientation and crystallinity in the final fiber structure.
  • filament refers to a fiber of indefinite or extreme length such as found naturally in silk. This term also refers to manufactured fibers produced by, among other things, extrusion processes. Individual filaments making up a fiber may have any one of a variety of cross sections to include round, serrated or crenular, bean-shaped or others.
  • Yarn refers to a continuous strand of textile fibers, filaments or material in a form suitable for knitting, weaving, or otherwise intertwining to form a textile fabric. Yarn can occur in a variety of forms to include a spun yarn consisting of staple fibers usually bound together by twist; a multi filament yarn consisting of many continuous filaments or strands; or a mono filament yarn which consist of a single strand.
  • fiber component encompasses fiber, monofilament, multifilament and yarn.
  • composite yarn refers to a yarn prepared from two or more yarns, which can be the same or different.
  • Composite yarn can occur in a variety of forms wherein the two or more yarns are in differing orientations relative to one another.
  • the two or more yams can, for example, be blended, parallel, wrapped one around the other(s), twisted together, or combinations of any or all of these, as well as other orientations, depending on the properties of the composite yarn desired.
  • Examples of such composite yarns are provided in U.S. Patents 4,777,789; 5,177,948; 5,628,172; 5,845,476; 6,351,932; 6,363,703 and 6,367,290, the contents of which are hereby incorporated by reference.
  • air interlacing refers to subjecting multiple strands of yarn to an air jet to combine the strands and thus form a single, intermittently commingled strand. This treatment is sometimes referred to as "air tacking.” This term is not used to refer to the process of "intermingling” or “entangling” which is understood in the art to refer to a method of air compacting a multifilament yarn to facilitate its further processing, particularly in weaving processes. A yarn strand that has been intermingled typically is not combined with another yarn. Rather, the individual multifilament strands are entangled with each other within the confines of the single strand.
  • the present invention is directed to a method for treating or coating a yarn component that is quick, efficient, low-cost and multi-dimensional.
  • multi-dimensional is used to denote the ability to provide multiple fiber or yarn treatments in a single pass through a treatment bath.
  • the present method is as depicted in Fig. 1.
  • Fig. 1 shows one or more yarn components (13) being passed through a treatment bath (11) in which is contained a treatment composition.
  • the treated yarn components are then wound around a heated roller (12) one or more revolutions, followed by takeup on tubes or bobbins (4).
  • the treatment composition can take any form, including but not limited to solutions, dispersions and emulsions.
  • the treatment composition contains at least one (co)polymer suitable for coating the yarn component.
  • This at least one (co)polymer can be in solution or present as a (co)polymer emulsion or dispersion.
  • the (co)polymer can be present in any desired amount in the treatment composition, preferably from about 1-15% by weight of the composition, more preferably from about 2-10% by weight, most preferably from about 3-9% by weight.
  • Preferred (co)polymers for use as this component are polyvinylchloride (PVC), polyurethane polymers and copolymers, and ethylene-vinyl acetate copolymers.
  • the treatment composition can optionally contain one or more additional treatment components, including but not limited to antimicrobial agents, antistatic agents, colorants, and lubricants.
  • the treatment bath contains the one or more (co)polymers and at least one of the additional components, more preferably at least two of the additional components.
  • the treatment composition comprises an aqueous solution or dispersion of ethylene-vinyl acetate copolymer, a colorant and an antimicrobial agent.
  • the components contained in the treatment composition are chemically compatible (i.e.
  • the treatment composition is preferably aqueous, although non-aqueous compositions are also included within the present invention. When non-aqueous compositions are used, proper precautions must be taken for removal of organic vapors during the drying step at the heated drying roller.
  • the treatment composition can be used at ambient or room temperature or can be heated or cooled as desired.
  • the yarn component to be treated can be made of or contain any natural or synthetic fiber, alone or in combinations or blends, including, but not limited to, cotton, wool, nylons, polyesters, polyethylenes, polypropylenes, aramids, glass, and metal fibers.
  • the component to be treated may be in the form of a monofilament fiber, multifilament fiber, yarns made from these fibers, composite yarns, or the components of composite yarns, such as the core or individual sheath or wrap layers of the composite yarn.
  • the process is used to treat the core of a composite yarn such as those disclosed in US 5,177,948 (already incorporated by reference above).
  • the composite yarn being treated has a core that contains no high performance fibers (in the present context, "high performance fibers” is defined as fibers having a tenacity of at least 10 g/den, such as glass, aramids, and extended-chain polyethylene).
  • high performance fibers is defined as fibers having a tenacity of at least 10 g/den, such as glass, aramids, and extended-chain polyethylene.
  • TMs process permits the preparation of composite yarns that are therefore cut-resistant or cut-proof, without the costly inclusion of high-performance fibers.
  • the process further permits the introduction of color into the product, as well as antimicrobial and or antistatic properties as desired, all in a single treatment bath, thus lowering production costs significantly.
  • the composite yarn contains a low-melting encasing yarn in the core, which has a softening point below the temperature of the heated drying roll (4), such that during the drying process, the encasing yarn softens and forms an encasing covering on the underlying fiber or yarn.
  • the composite yarn that results has a coating of (co)polymer on the exterior of the outer sheath or wrap layer, with an additional coating of the encasing yarn forming a layer between the core and innermost sheath or wrap layer.
  • Suitable encasing yarns include, but are not limited to, those disclosed in US 6,230,524 and US 6,367,290, the contents of which are hereby incorporated by reference.
  • the present process can be used to improve the cut-resistance of a composite yarn, and can also improve the appearance and/or hand of a composite yarn.
  • the resulting product has high levels of fuzz present on the exterior surface of the yarn.
  • conventional composite yarns have a problem with evenness of the exterior surface properties, particularly in dyeing or coloring of the composite yarn.
  • the treatment bath contains a colorant in addition to the (co)polymer
  • the colorant is evenly distributed by the treatment composition, and evenly colors the (co)polymer coating. This is particularly effective in providing better uniformity of color in the final product, as the surface layer is all the same (co)polymer, and thus has more uniform dye or colorant uptake compared to uptake of the dye with the surface of the composite yarn itself, which may have multiple types of fibers exposed at the surface.
