METHOD FOR PRODUCING OF FIBER OR THREAD FROM REGENERATED CELLULOSE Russian patent published in 2004 - IPC

FIELD: textile industry, in particular, production of knitted or nonwoven textile surfaces. SUBSTANCE: method involves extruding solution of cellulose derivatives or the same cellulose derivatives in melted state through at least one spinneret opening; regenerating cellulose by processing resultant thread through stages providing synthesis of cellulose silyl derivative with silylation agent; withdrawing cellulose silyl derivative from reaction medium; extruding cellulose silyl derivative in the form of solution or melt; treating obtained thread with desilylation agent for regeneration of cellulose and recuperation of siloxanes; regenerating silylation agent based on siloxanes and recuperated at cellulose regeneration stage. Method allows fiber or thread to be produced with properties approximating to those of threads produced from synthetic materials. EFFECT: improved quality and reduced cost of fiber or thread, and provision for producing of fiber or thread without deteriorating of environment. 25 cl, 19 ex
