Title: Solvent-spun cellulose fiber excellent in pill resistance and peach-skin processability, its fiber structure and its production
Inventor: OTOI KIYOSHI
IPC: D06M101/06
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To produce a modified Tencel(R) raw stock having high pill resistance and excellent peach-skin processability in a compatible manner and capable of, especially, performing spinning to obtain excellent yarn quality under ordinary spinning conditions, without using a rubbing-beating process which usually has troubles of unevenness in the points of productivity and cloth strength, etc. SOLUTION: In a modification process of Tencel(R) fiber and its fiber structure, especially raw stock using cellulase, the amount of an anionic surfactant attached on the fiber is reduced to 0.05wt.% or bellow by washing with hot water in advance, and a linear velocity of a liquid flow of cellulase processing is controlled at <=5m/sec. These enable the cellulase processing at extremely mild conditions with total enzyme potencies of <=25000 unit, so that a single-fiber strength variation is suppressed to a narrow range of <=10% at the average single fiber strength of 3.0-4.3g/d.  Further, the combination of the cross-linking modification using a glycidyl compound with the above process enables the production of a Tencel(R) fiber having high pill resistance and excellent peach-skin processability in a compatible manner and especially the production of a Tencel(R) raw stock having excellent spinnability.
