This moisture-permeable, waterproof fabric is obtained by a process comprising coating a resin solution, containing a fluorine-containing polyurethane resin and a polyurethane resin having a low degree of polymerization, on at least one side of a textile fabric, followed by coagulating the resin, removing the solvent, drying the fabric and applying a water repellent.

Abstract: A non-woven mat of fibrous thermoplastic insulation is produced by melt blowing recycled polyethylene teraphthalate (PET). The PET is melted, pressurized and extruded from an extrusion head into substantially continuous fibers that are subjected to turbulent high velocity air that attenuates the fibers. The fibers are then collected on a collection device building up a non-woven mat. The collection device is spaced from the extrusion device forming a flight path for the fibers that is sufficiently long that the fibers split apart under the force of the high velocity air, fibrillating into a plurality of very fine fibrils of under 15 microns in diameter. These fibrils are analogous to goose down and greatly enhance the loft and R value of the mat.

Abstract: A method and an apparatus for the production of a three-dimensional textile (3), wherein the textile (3) is formed from two sheets of textile (5, 6) placed face to face and connected together by a plurality of threads (10), impregnated with resin and inserted between two layers (16, 17) so as to form a layered structure (1). This layered structure (1) is inserted between two dies (25, 26) of a heated press which is subsequently closed to allow the resin impregnating the structure to distribute itself uniformly. The layers (16, 17) are then attached by vacuum to the faces of the dies (25, 26) which are then opened through a first controlled distance within the limit of the elastic recovery of the three-dimensional textile (3). The outermost layers of the structure (1) are then polymerized by heating the dies (24, 26) while the resin impregnating the threads (10) remains in a plastic state.

Abstract: PVP-coated asymmetric hollow fibers made from SIXEFT.TM.-Durene, a polyimide made from 2,2-bis[3,4-dicarboxyphenyl] hexafluoropropane dianhydride and 2,3,5,6-tetramethylphenylene diamine monomers, and a process for making such fibers. These coated fibers have a separation factor that exceeds 6 for oxygen and nitrogen and a permeance of at least about 10 ppm cc(STP)/(sec cm.sup.2 cm-Hg). A polymer dope comprising SIXEF.TM.-Durene in a solvent system containing N-methyl-2-pyrrolidone ("NMP") and an organic acid such as propionic acid ("PA") is prepared by polymerizing the polyimide monomers in NMP to form a polyamic acid polymer and imidizing this polymer using the acid anhydride. Water released from the polymer in the imidization reaction converts the anhydride to acid. The dope is wet-spun into hollow fibers; the fibers are coagulated in water. The fibers are then evenly coated with PVP, preferably by dipping the fibers in a dilute PVP solution.

Abstract: A polymer composite reed for a reed valve is provided, wherein the reed has improved mechanical properties as a result of its construction and is highly resistant to chemical and thermal attack. The improved mechanical properties of the reed are primarily due to the reed being reinforced with two plies of fabric having a harness satin weave, which provides the reed with a flexural modulus that is substantially greater in one direction of the reed. The chemical and thermal properties are primarily due to the semicrystalline thermoplastic material from which the reed is formed. In addition, the thermoplastic material enhances the fracture toughness of the reed to improve the durability of the reed. As a result, the reed is highly suitable for applications requiring long life under high speed, cyclic loading, such as that found in two-stroke and four-stroke internal combustion engines for the automobile industry.
