Abstract
1,136,412. Regenerated cellulose filaments. PHRIX-WERKE A.G. 22 July, 1966 [19 Aug., 1965], No. 33196/66. Heading B5B. Regenerated cellulose filaments are spun from a spinning bath containing formaldehyde, and the coagulated filaments are consecutively stretched in steam at a temperature of 95 to 110 C. and in a hot aqueous bath at a temperature of 70 to 95 C. to between 300 and 500% of their original length. Preferably, the coagulated filaments enter the hot aqueous bath directly from the steaming zone. In a preferred method, the filaments are made by coagulation of an unripened viscose having a cellulose content between 4 and 7%, an alkali factor of 1.0 to 1.4 and a gamma value exceeding 70, into a cold spinning bath which contains no heavy metal salts, 60 to 90 g. per. 1. of sulphuric acid, 5 to 15 g. per. 1. of formaldehyde and 100 to 150 g. per. 1. of anhydrous sodium sulphate. Desirably, the viscose has a cellulose content between 4.5 and 5.5%: an alkali factor of 1.25 to 1.35% and a gamma value exceeding 80, and is coagulated in a cold spinning bath at a temperature between 25 and 27 C. which contains 68 to 72 g. per. 1. of sulphuric acid, 10 to 13 g. per. 1. of formaldehyde and 130 to 140 g. per. 1. of anhydrous sodium sulphate. In apparatus as shown a tube 3 consisting of a material which is resistant to acid, to formaldehyde and to temperatures up to 110 C. is located between the upper godet wheel 2 of a spinning machine and a hot aqueous bath 5, there being an inlet 4 for supplying steam into the tube. Suitably the steaming tube is placed as shown vertically between the upper godet wheel and the hot aqueous bath with the bottom end of the steaming tube dipping into the hot aqueous bath, which may contain an undriven deflecting element 6 for the yarn.
