摘要:
Included are elastomeric fibers and method for preparing such fibers, which include a bio-derived butanediol. The bio-derived butanediol is used to prepare a polymeric glycol composition, which is contacted with a diisocyanate and spun to provide an elastomeric fiber.
摘要:
Disclosed herein are spandex fibers having reduced friction combined to provide a multiple end spandex package. The spandex fibers have a sheath-core cross-section with a lubricating additive is included in the sheath. A fusing additive specifically excluded to avoid coalescence among the individual filaments in the yarn. When combined in a yarn package, the multiple filaments are separable.
摘要:
An article comprising a polyurethane composition and an array of fibers wherein said array of fibers are embedded in said polyurethane composition such that a portion of said fibers extends beyond an internal surface of said molded article and an external surface of said molded article.
摘要:
The present invention pertains to a fluorine-free composition for treating textile articles being water repellant, sol resistant and stain resistant, especially carpets comprising a first composition comprising an aqueous silicone emulsion, an aqueous dispersion of a silane quaternary ammonium salt and water and a second composition comprising a soil repellency component that is an aqueous dispersion of colloidal organosiloxane copolymers.
摘要:
An elastic fiber is provided that includes polyurethane and/or polyurethaneurea and an additive such as polystyrene, an acrylic polymer, polyvinylpyrrolidone, copolymers thereof, derivatives thereof, and combinations thereof. The elastic fiber is useful in laminate structures, such as disposable hygiene articles as wells as in knit, woven and nonwoven fabric constructions.
摘要:
A fiber and method for making the same is disclosed that comprises a surface treatment, wherein the surface treatment comprises at least one clay nanoparticle component present in an amount greater than 2000 ppm on the surface of the fiber. Also disclosed is a fiber and method for making the same, comprising a surface treatment, wherein the surface treatment comprises at least one clay nanoparticle component and excludes flourochemicals.
摘要:
Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
