The present disclosure relates to materials, and specifically to materials such as sheet, molded or extruded polymer materials containing flake, formed, powdered, granulated or splintered borosilicate glass for heat rejection or mitigation and enhanced durability and strength. The invention provides a synthetic substrate that includes: 1 to 70 wt % borosilicate glass having an average size of 0.1 to 50 um; and 30 to 99 wt % polymer material, wherein the synthetic substrate has either a denier ranging between 0.1 to 20.0 or a thickness ranging between 0.1 to 20 MIL, which provides thermal management properties including reduction in solar absorptance and net power absorbed by surfaces. The greater the intensity of the solar radiation the more reactive the borosilicate becomes, reflecting and dissipating an increased level of energy.

A problem of the present invention is to provide a composite yarn, a fabric, and a fiber product, which are excellent in cotton-like appearance, texture, and snagging resistance, and preferably excellent in see-through-preventing properties and water absorbing and quick drying properties. The solution is to obtain a composite yarn using a thick and thin yarn and a crimped yarn and to obtain a fabric, if desired.

A method of producing synthetic yarn having polytetrafluoroethylene (PTFE) properties is described. The method providing: applying a PTFE additive to a partially oriented yarn (POY) during one or more finishing processes of the POY to produce a PTFE enhanced POY having PTFE on the surface of the fibers of the PTFE enhanced POY.

A false twist yarn includes dyeable polyolefin fibers characterized as being polymer alloy fibers each having a sea-island structure in which a polyolefin (A) is the sea component and a polyester (B) having cyclohexanedicarboxylic acid compolymerized therein is the island component, and in which the dispersion diameter of the island component in a fiber cross section is 30-1000 nm, wherein the number of the polymer alloy fibers is three or more, and the polymer alloy fibers have physical properties (1) and (2): (1) crimp recovery (CR) being 10-40%; and (2) hot-water dimensional change being 0.0-7.0%. The polyolefin false twist yarn is capable of developing vivid and profound colors even though the polyolefin fibers therein are light in weight.

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.

The present invention provides a thermoplastic polyurethane elastic fiber which exhibits excellent runnability during the production process of paper diapers. A polyurethane elastic fiber according to the present invention has the following characteristics: (a) the polyurethane elastic fiber is composed of a multifilament; (b) the total fineness thereof is from 160 dtex to 2,000 dtex; (c) the outflow start temperature thereof is from 160° C. to 220° C. as measured by a flow tester at an extrusion load of 49 N, a start temperature of 120° C. and a heating rate of 3° C./min; and (d) the bonding force between single yarns is 0.4 cN or more.

A stretch yarn includes a multifilament including fibers having a coiled crimping form in a fiber axial direction, wherein a coil diameter distribution of crimping in the fiber has two or more groups, a ratio of a maximum group average value to a minimum group average value of the coil diameter (a maximum group average value/a minimum group average value) is less than 3.00, and a cross section of the fibers constituting the multifilament is an eccentric core-sheath cross section.

An object of the present invention is to provide a fluid-separation carbon membrane module that can suppress defects on a surface of a carbon membrane or breakage of the carbon membrane and suppress suction of a potting material even in a case where a carbon membrane having low ductility is used, and the main idea of the present invention is a fluid-separation carbon membrane module in which a plurality of covered carbon membranes in which at least one covering yarn is helically wound around one or two fluid-separation carbon membranes are housed in a vessel.

A method includes forming a multi-pick yarn package through winding multiple oriented yarns onto a spool, with the multiple oriented yarns serving as weft yarns forming adjacent substantially parallel yarns wound together. Each of the multiple oriented yarns is formed through drawing each of multiple yarns from a corresponding supply package. The method also includes, using the multi-pick yarn package, simultaneously inserting the weft yarns in a single pick insertion event of a pick insertion apparatus of a loom apparatus in which the simultaneously inserted weft yarns are to be conveyed through a set of warp yarns to produce an incremental length of a woven textile fabric.

Processes are provided for the manufacture of color effect face yarns for use in tufted goods. These color effect yarns may exhibit unique color effects and contain a lower overall denier, thereby allowing the production of tufted goods with a greater than normal tuft density per unit area. Consequently, this can result in finer color effects and/or sharper definition of color effects in the tufted goods and expands the design possibilities for such products.
