Core Is Synthetic Polymeric Material Patents (Class 442/191)
  • Patent number: 11359311
    Abstract: A method and a system disclosed include drawing each of multiple synthetic yarns from a corresponding supply package to form an oriented yarn. Filaments within the oriented yarn are twisted and detwisted to provide texture thereto, to provide a low stability interlacing during weaving, and to intermingle the filaments, and a uniform air pressure is applied to the oriented yarn to provide a counter-twist. Also, a multi-pick yarn package is formed based on winding all formed oriented yarns, which serve as weft yarns forming adjacent substantially parallel yarns wound together, onto a spool. These weft yarns are simultaneously inserted in a single pick insertion event of a loom apparatus, and conveyed across a warp shed of the loom apparatus through a set of warp yarns. The set of warp yarns and the conveyed weft yarns are interlaced to produce an incremental length of a woven textile fabric.

  • Patent number: 9131790
    Abstract: The proliferation of the thread count of a woven textile is accomplished through simultaneous insertion, within a single pick insertion event of a loom apparatus, of multiple adjacent parallel yarns drawn from a multi-pick yarn package. In one or more embodiments, multiple texturized polyester weft yarns of denier between 15 and 50 are wound on a single bobbin in a parallel adjacent fashion such that they may be fed into an air jet pick insertion apparatus of an air jet loom to weave a textile that has between 90 to 235 ends per inch cotton warp yarns and between 100 and 765 polyester weft yarns.

    Abstract: An allergen-barrier fabric includes a tightly-constructed fabric substrate, woven from 0 to 45% continuous synthetic filament yarns and 55 to 100% natural or synthetic spun yarns. The fabric substrate is finished to produce a fabric with a mean pore size of 4 to 10 microns, an air permeability of 0.5-25 cfm, a mean fabric flexibility of 0.5 to 6.5 grams (bending resistance), and a moisture vapor permeability in excess of 800 g/m2/24 hours. This fabric provides a barrier to mite-induced allergen particles. Various additional finishes can be included on the fabric. For example, an antimicrobial finish may be provided on the fabric to extend fabric wearlife by providing protection against mold and mildew. As another alternative, a fluorochemical finish can be provided to extend fabric wearlife by providing protection against fluid stains.

    Abstract: Yarns consisting essentially of about 85 to 90 weight % hydrophobic fiber and about 10 to 15 weight % hydrophilic fiber can be made into fabrics that exhibit a combination of properties that make them strongly preferred by wearers, as compared even to fabrics made from yarns containing only 5% more, or 5% less, of the hydrophilic fiber. More particularly, these novel yarns yield fabrics capable of quickly absorbing perspiration from a wearer's skin and yet capable of quickly releasing that moisture, resulting in surprising levels of wearer comfort and wearer preference.
