Abstract

1,096,062. Filaments of polyvinyl alcohol. KURASHIKI RAYON KABUSHIKI KAISHA. Feb. 4,1965 [Feb. 11, 1964], No. 4987/65. Heading B5B. Polyvinyl alcohol filaments of high resistance to abrasion are made by conventionally dry spinning or semi-melt spinning a solution of polyvinyl alcohol to form filaments which are successively heat stretched, further heat treated and immersed in an aqueous formalization bath at a temperature of from 70‹ to 100‹ C., preferably of from 75‹ to 95‹ C. The formalization bath comprises formaldehyde at a concentration of from 50 to 200 (preferably from 80 to 150) grams per litre, sulphuric acid at a concentration of from 1 to 50 (preferably from 2 to 35) grams per litre, and sodium sulphate at a concentration of 50 to 300 (preferably from 100 to 200) grams per litre measured as anhydrous sodium sulphate. In the heat stretching, the filaments preferably are longitudinally stretched more than 500% at a temperature above 180‹ C.; the further heat treatment of the filaments preferably is a heat shrinkage of from 20 to 30% at a temperature above 180‹ C. The filaments may be made into ropes, cords and nets, for example fishing nets.
