REGENERATED CELLULOSIC FIBER EXCELLENT IN DYEABILITY AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To produce a regenerated cellulosic fiber good in dyeability with an acid dye and a metallized dye and color fastness to light for a dyed product and provide a method for producing the regenerated fiber. ;SOLUTION: This regenerated fiber is obtained by adding and mixing a solution of wool with a viscose, spinning the resultant mixture solution and is excellent in dyeability. The regenerated fiber is produced by adding and mixing the solution of wool with the viscose, then discharging the resultant viscose from a spinning nozzle, coagulating and regenerating the discharged viscose, subsequently scouring and drying the formed fiber. The resultant fiber contains the wool in an amount of 1-40wt.% based on the cellulose.;COPYRIGHT: (C)1997,JPO
