Abstract

1532770 Hydrophilic filaments BAYER AG 21 Feb 1977 [25 Feb 1976] 07174/77 Heading B5B Porous filaments are prepared by dry spinning a solution of a polymer to which solution is added 5-50% by wt. of an additive substance which is solid under ambient conditions and which (a) has a m.p.t. or sublimation point higher than that of the spinning solvent used; (b) is readily miscible with the spinning solvent and a washing liquid; and (c) is a non- solvent for the polymer to be spun, and washing the additive out of the freshly spun filaments. Filaments have pronounced core-jacket structures and may be non-circular according to processing conditions. Suitable polymers are polyacrylic nitriles and polyamides or those which optionally contain heterocyclic rings. [GB1532770A]
