  • Patent number: 10132614
    Abstract: An optical fiber includes multiple optical waveguides configured in the fiber. An interferometric measurement system mitigates or compensates for the errors imposed by differences in a shape sensing optical fiber's response to temperature and strain. A 3-D shape and/or position are calculated from a set of distributed strain measurements acquired for a multi-core optical shape sensing fiber that compensates for these non-linear errors using one or more additional cores in the multicore fiber that react differently to temperature changes than the existing cores.

  • Patent number: 8276358
    Abstract: A process of manufacturing a ultra-soft yarn includes wrapping a roving material with a yarn by a low twist-multiplier of about 1˜4, wherein the roving material is drawn at a draw ratio preferably between 1 and 10, wherein the ultra-soft yarn has a fluffy structure, which can provide better softness, draping property, and hand feel to users. Fabric including the ultra-soft yarn is also provided.

  • Publication number: 20120244771
    Abstract: Composite yarns have a filamentary core provided with at least one elastic performance filament and at least one inelastic control filament. A fibrous sheath, preferably formed from spun staple fibers, surrounds the filamentary core, preferably substantially along the entire length thereof. The at least one elastic performance filament most preferably includes a spandex and/or a lastol filament. The at least one inelastic control filament is most preferably formed of a textured polymer or copolymer of a polyamide, a polyester, a polyolefin and mixtures thereof. Preferably, the fibrous sheath is formed of synthetic and/or natural staple fibers, most preferably staple cotton fibers. The elastic composite fibers find particular utility as a component part of a woven textile fabric, especially as a stretch denim fabric, which exhibits advantageous elastic recovery of at least about 95.0% (ASTM D3107).

  • Patent number: 8209948
    Abstract: The multilayer-structured spun yarn of the present invention is a multilayer-structured spun yarn C composed of a core fiber A and a cover fiber B that wraps around the core fiber; the core fiber A is in a range of 20 to 50 wt %; the cover fiber B is in a range of 50 to 80 wt %; the core fiber A contains a para-aramid fiber and is a stretch breaking twist yarn; the cover fiber B contains a flame-retardant acrylic fiber, a polyetherimide fiber, or a meta-aramid fiber; the direction of twist of the stretch breaking yarn and the direction of twist of the multilayer-structured yarn are the same; and the multilayer-structured yarn C has a twist number 1.2 to 1.6 times greater than that of the stretch breaking yarn. The heat-resistant textile of the present invention uses the aforementioned multilayer-structured spun yarn. The heat-resistant protective suit of the present invention uses the aforementioned heat-resistant textile.
