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 the cellulase process is carried out under extremely mild conditions with total enzyme potencies of <=25000 unit, so that the average single fiber strength is adjusted to 3.0-4.3g/d. Further, the combination of the suppression of the variation of single fiber strengths to a narrow range of <=20% and the cross-linking modification using a glycidyl compound 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. |
