Abstract (en)

[origin: EP0071086A1] 1. A process for the production of bonding fibers by combining a polymer dispersion, containing an anionic or nonionic dispersant, with an aqueous solution of a cationic precipitant, accompanied by mechanical formation of fibers, wherein the dispersion employed has thread-forming properties and either a) has a viscosity which increases under shear stress and therefore thickens automatically under the conditions of fiber formation, or b) contains, as thickener, from 0.05 to 10% by weight, based on the dispersion, of a high molecular weight polymer or copolymer of acrylic or methacrylic acid in the form of its alkali metal salts, high molecular weight polyacrylamide and/or high molecular weight polyethylene oxide.
