COMBINED FILAMENT YARN OF CELLULOSE ESTER

摘要

PROBLEM TO BE SOLVED: To obtain a combined filament yarn of cellulose ester which has an excellent touch, swelling feeling and color development when made into a fabric. SOLUTION: The combined filament yarn of cellulose ester comprises a highly shrinkable cellulose ester fiber (A) having a boiling water shrinkage percentage of 7-25% and a low shrinkable cellulose ester fiber (B) having a boiling water shrinkage percentage of 2-5% and satisfies formula (I) 5%≤the boiling water shrinkage percentage of the cellulose ester fiber (A)-the boiling water shrinkage percentage of the cellulose ester fiber (B)≤20%.
