摘要： Manufacture of a non-woven web of man-made filaments in which one or more strands of filaments, directed parallel to each other, leaving one or more spinnerets are forwarded, each, by means of an air jet to a spreading plate for the filaments, and the resulting layer of spread filaments and air leaves the plate and advances to a moving support, upon which the filaments are deposited randomly to form a web which will then be bonded in known manner. In order to improve the isotropy of the web, the layer of spread filaments and air is guided to a fixed deflector plate forming a slit with the discharge edge of the stationary spreading plate, said slit allowing passage of the filaments but braking the air carried along with the filaments, and the layer is then subjected to an air jet directed transversely to the path of said deflected web and generally in a direction parallel to the surface of the moving support.

摘要： In a process for preparing a polyvinyl alcohol yarn of high tenacity, a solution of polyvinyl alcohol in an organic solvent is extruded from a spinneret into a coagulation bath through an air gap or inert gas gap, and the extruded solution is drawn. The spinneret has capillaries which are at least five times their diameter in length and the concentration of the polyvinyl solution is at least 30-(M.sub.v /20,000) in percent by weight of the polyvinyl alcohol solution.

摘要： The invention pertains to a process for preparing thermoplastic fibres by melt-spinning an alternating co-polymer composed of alkenes and carbon monoxide in which the polymer is heated to a temperature of at least TNF+5° C., with TNF being the temperature at which the molten polymer is free of crystallization nuclei, and where the residence time of the polymer at a single temperature or different temperatures above the polymer melting point satisfies: [ ∑ n = 1 ∞ ⁢ t n · exp ⁢ ⁢ ( A + B T n ) ] ≤ 1. wherein tn is the residence time (in minutes) of the polymer at a temperature Tn (in K, with Tn>Tm) and A and B are determined by measuring the viscosity of the polymer at different temperatures and residence times.

摘要： Core-sheath fibers are useful as textile reinforcing materials in rubber items having rubber adhesion of 180 to 260 N/2 cm. The fiber core is a high-melting (co)polyester and the sheath is a high-melting unsaturated copolyester. The high-melting unsaturated copolyester is made from at least one unsaturated dicarboxylic acid coconstituent, which contains at least 2 mole-%, based on dicarboxylic acid components, of alkylmaleic acid, having a 1 to 18 carbon atom alkyl group; alkylenesuccinic acid having a 1 to 18 carbon atom alkylene group; or their polyester-forming derivatives.
