Abstract

879,995. Artificial filaments, films &c. ALGEMENE KUNSTZIJDE UNIE N.V. May 29, 1959 [June 2, 1958], No. 18297/59. Addition to 871,334. Class 2(2). Artificial threads, bands, films and like products are made by spinning viscose containing 1 %-6 % by weight (based on the cellulose in the viscose) of at least one cation-active compound with the formula: in which R 1 is an alkyl, aryl or alicyclic radical, preferably containing at least 6 carbon atoms, R 2 is an alkyl radical with 1-3 carbon atoms, n is a whole number of 2-5, x and y are each whole numbers, the sum of x+y preferably being 2-50, and Z is an anion having substantially no surface activity, the viscose having an ammonium chloride number of at least 13, into a spinning bath containing a maximum of 7% by weight of sulphuric acid, at least 2 % by weight of zinc sulphate and at least 0À04% by weight of at least one compound with the formula: in which R 3 is an aliphatic chain with at least 8 carbon atoms, n is 2, 3 or 4 and x and y are whole numbers, the sum of x+ y being at least 5, and then drawing the products. The cationactive compound is preferably injected into the viscose and thoroughly mixed therewith immediately prior to spinning. The spinning bath, which preferably has a temperature of 47 ‹-57 ‹C., may also contain 10%-25 % by weight of sodium sulphate. The spun products may be stretched in the spinning bath or in a second bath of elevated temperature containing dilute sulphuric acid, to which salts, e.g. sodium sulphate, magnesium sulphate and/or zinc sulphate, may be added.
