MOLDING SOLUTION FOR PRODUCTION OF THERMALLY STABILIZED CELLULOSE TRIACETATE FIBERS Russian patent published in 2000 - IPC

Abstract RU 2155831 C2

FIELD: paper-and-pulp industry. SUBSTANCE: invention relates to technology of preparing concentrated solutions of cellulose carboxylic acid esters and mixed esters for processing it into fibers and films. Solution, in particular, contains 19-21% of cellulose triacetate and 0.4-1.0% of N-(5'-nitro-2'-furfurylidene)-3-amino-2'- oxazolidene in organic solvent. Fibers, when heated for 18 h at 230 C, lose no more than 44% of their initial weight. EFFECT: increased heat resistance of fibers. 1 tbl, 3 ex
