Definitions

  • the present invention generally relates to siliconized synthetic filament yarn, and to articles comprising and methods of forming the same.
  • U.S. Patent Publication 20070032155 which is commonly-owned with the present application, discloses a yarn comprising siliconized micro-denier polyester staple fibers and macro-denier staple fibers.
  • the present invention satisfies the need for improved yarn having desirable properties, such as hand-feel.
  • the present invention may address one or more of the problems and deficiencies of the art discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore, the claimed invention should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed herein.
  • Certain embodiments of the presently-disclosed yarn, articles comprising the yarn, and methods for making the yarn have several features, no single one of which is solely responsible for their desirable attributes. Without limiting the scope of the yarn, articles, and methods as defined by the claims that follow, their more prominent features will now be discussed briefly. After considering this discussion, and particularly after reading the section of this specification entitled “Detailed Description of the Invention,” one will understand how the features of the various embodiments disclosed herein provide a number of advantages over the current state of the art. For example, incorporation of embodiments of the inventive yarn into articles such as fabric gives the resultant article an increased softness as sensed by the hand or skin. Articles comprising the embodiments of the inventive yarn can also take on more of a spun, natural fiber quality, while giving the fabric an inherent water resistance and reducing the time needed for becoming completely dry after being exposed to wet conditions.
  • the invention provides a yarn comprising a plurality of synthetic filament plies bundled together in the form of a yarn strand, wherein the yarn strand is a siliconized strand.
  • the invention provides an article comprising the yarn of the first aspect of the invention.
  • the invention provides a method of making yarn, comprising:
  • FIGS. 1A and 1B depict simplified profile views of sections of yarn according to certain embodiments of the invention.
  • FIG. 2 depicts a section of yarn according to an embodiment of the invention.
  • the invention provides a yarn comprising a plurality of synthetic filament plies bundled together in the form of a yarn strand, wherein the yarn strand is siliconized.
  • the present invention provides a filament yarn.
  • filament plies are single long threadlike continuous textile fibers/strands. Unlike staple fibers, which are of finite length (typically sold in lengths up to 120 mm), filaments are of indefinite length, and can run the entire length of yarn, even for yards or miles. Indeed, the length of a filament is often limited not by the filament itself, but by the yarn that comprises it.
  • the filament plies are long continuous fibers of indefinite length, with length often being dictated by the final yarn in which the plies are employed.
  • the filament plies range in length from 5 inches to several miles, including any and all ranges and subranges therein.
  • the filaments may be at least 5 inches in length (e.g., at least 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or 100 inches in length, or any range or subrange therein).
  • the filaments may be at least 1 foot in length (e.g., at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230
  • Synthetic filaments may be created by a process known as extrusion (which can also be called melt spinning).
  • synthetic polymer composition e.g., polyester
  • the liquid polymer may be forced through a dye called a spinneret.
  • the spinneret often has many small holes through which the liquid passes.
  • the liquid polymer streams are cooled upon exiting the spinneret, resulting in long strands of continuous synthetic fibers.
  • the extruded filaments may optionally be combined with those of another (e.g., an adjoining) spinneret to increase the number of filaments in a bundle.
  • a bundle of filaments maybe drawn (stretched) to make each filament thinner, and may optionally be texturized, as described below.
  • the synthetic filaments may be solid or hollow.
  • the plurality of synthetic filament plies is made of up two or more filaments. In some embodiments, the plurality of synthetic filament plies is made up of two to over one hundred filaments.
  • the plurality of non-siliconized synthetic filament plies is made up of 2 to 500 filaments (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91,
  • Synthetic fibers that may constitute the synthetic filament plies include any synthetic fiber known in the art as being conducive to the preparation of textile materials. Many synthetic fibers are known in the art, and any desired synthetic fibers may be used in the invention. Indeed, different fibers have different properties, and lend themselves toward advantageous uses in different applications. This information is well within the purview of persons having ordinary skill in the art. While a wide array of synthetic filament plies may be used in the invention, in some embodiments, the synthetic fibers that constitute the synthetic filament plies are selected from the group consisting of polyamide, polyester, acrylic, acrylate, acetate, polyolefin, nylon, rayon, lyocell, aramid, spandex, viscose, and modal fibers, and combinations thereof.
  • the synthetic fiber is polyester.
  • the polyester is selected from poly(ethylene terephthalate), poly(hexahydro-p-xylylene terephthalate), poly(butylene terephthalate), poly-1,4-cyclohexelyne dimethylene (PCDT) and terephthalate copolyesters in which at least 85 mole percent of the ester units are ethylene terephthalate or hexahydro-p-xylylene terephthalate units.
  • the polyester is polyethylene terephthalate.
  • the filaments of the plurality of synthetic filament plies are non-siliconized (i.e., the individual filaments have not been subject to siliconization, and thus exterior surfaces spanning the circumference of the filaments are not coated with silicon-containing material).
  • the plurality of synthetic filament plies are bundled together in the form of a yarn strand, wherein the strand is siliconized.
  • the synthetic filament plies are bundled together parallel to one another, as shown in yarn segment 100 in FIG. 1A .
  • the synthetic filament plies are bundled together by twisting the plies, as shown in yarn segment 200 in FIG. 1B .
  • other texturizing techniques are performed on the bundle of filament plies to disrupt the parallelization of the filaments. Such techniques may serve, for example, to add bulk without adding weight, which can make the resultant yarn seem lighter in weight, have improved hand-feel (softness), appear more opaque, and/or have improved temperature insulating properties. While any art-acceptable texturizing processes may be employed, examples of texturizing processes conducive to use in the invention include crimping, looping, coiling, crinkling, twisting then untwisting and knitting then deknitting.
  • the resultant yarn strand includes an exterior portion 10 , which is siliconized. While the exterior portion 10 is depicted as a continuous surface in FIGS. 1A and 1B , persons having ordinary skill in the art will appreciate that, in many embodiments (e.g., depending on, inter alia, the number of filaments comprised within the yarn, how tightly the filaments are bundles, and texturization), the exterior portion will not appear continuous. This is the case, for example, in the embodiment of inventive yarn depicted in FIG. 2 .
  • siliconized means that the yarn is coated with a silicon-comprising composition (e.g., a silicone). Siliconization techniques are well known in the art, and are described, e.g., in U.S. Pat. No. 3,454,422.
  • the silicon-comprising composition may be applied using any method known in the art, e.g., spraying, mixing, dipping, padding, etc.
  • the silicon-comprising (e.g., silicone) composition which may include an organosiloxane or polysiloxane, bonds to at least an exterior portion of the yarn.
  • the silicone coating is a polysiloxane such as a methylhydrogenpolysiloxane, modified methylhydrogenpolysiloxane, polydimethylsiloxane, or amino modified dimethylpolysiloxane.
  • the silicon-comprising composition may be applied directly to the yarn, or may be diluted with a solvent as a solution or emulsion, e.g. an aqueous emulsion of a polysiloxane, prior to application. Following treatment, the coating may be dried and/or cured.
  • a catalyst may be used to accelerate the curing of the silicon-comprising composition (e.g., polysiloxane containing Si—H bonds) and, for convenience, may be added to a silicon-comprising composition emulsion, with the resultant combination being used to treat the exterior surface of the yarn.
  • Suitable catalysts include iron, cobalt, manganese, lead, zinc, and tin salts of carboxylic acids such as acetates, octanoates, naphthenates and oleates.
  • the yarn may be dried to remove residual solvent and then optionally heated to between 65° and 200° C. to cure.
  • the silicon-comprising compound does not comprise silicon dioxide.
  • Denier is a unit of measure defined as the weight in grams of 9000 meters of a yarn or fiber. It is a common way to specify the weight (or size) of the yarn or fiber. Fibers that are 1.0 denier have a diameter of approximately 10 micrometers. Micro-denier fibers are those having a denier of 1.0 or less while macro-denier fibers have a denier greater than 1.0. Denier per filament, or dpf, is a common way of specifying a multi-filament yarn. A yarn described as 75d/144f refers to a yarn having an overall denier of 75 (meaning 9000 meters of said yarn would weigh 75 grams), while the number of filaments comprising the yarn would be 144. This yarn would be considered a micro-denier yarn because its individual strands would have a denier of 75 divided by 144, or 0.52, which is lower than 1.0 denier.
  • the inventive yarn has a dpf of 0.2 to 15 (e.g., 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0,
  • the synthetic filaments have a denier of 0.1 to 10 denier (e.g., 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9
