摘要:
Copolymers which are composed of at least 4 monomers, including (meth)acrylate compounds containing perfluoroalkyl groups, are suitable for the treatment of fiber materials. The copolymers are usually used here in the form of aqueous dispersions. The fiber materials are in particular fabrics, for example made of polyolefin. Treatment with the copolymers imparts to them oil- and water-repellent properties and also repellent properties toward low molecular weight alcohols.
摘要:
Fibers that are formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density are provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. Fibers are thereafter formed and then stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”).

This invention relates to an aluminum conductor composite core reinforced cable (ACCC) and method of manufacture. An ACCC 303 cable (300) has a composite core surrounded by an outer film (305) and at least one layer of aluminum conductor (306). The composite core (303) comprises a plurality of fibers from at least one fiber type in one or more matrix materials. According to the invention, unique processing techniques such a B-Staging and/or film-coating techniques can be used to increase production rates from a few feet per minute to sixty or more feet per minute.
摘要:
A coated yarn prepared by coating a polyolefin yarn with a coating composition comprising a polyolefin resin and a flame retardant is provided, wherein the polyolefin is selected from the group consisting of a polyethylene resin, a polyethylene copolymer resin, a polypropylene resin and a polypropylene copolymer resin. The coated yarn can readily be recycled to produce a coreless yarn useful as a flooring material or other industrial materials, which improves the flame retardancy of conventional non-PVC coated yarns. A fabric woven from the coated yarn is useful in the preparation of a blind, a flooring material, wall paper, household items and other interior elements.
