VISCOSE RAYON FIBER, METHOD FOR PRODUCING THE SAME AND VISCOSE RAYON FIBER ASSEMBLY

摘要

PPROBLEM TO BE SOLVED: To obtain a viscose rayon fiber having high bulkiness and being rigid, to provide a method for producing the same and to obtain a viscose rayon fiber assembly. PSOLUTION: The viscose rayon fiber is a viscose rayon fiber obtained by coagulating and regenerating viscose, has 40-160 dtex fineness and an indeterminate fiber cross section and comprises constrictions (10 and 11) in which the lengths of arm parts (12, 13 and 14) forming the constrictions (10 and 11) are 2.5 times the widths of the arm parts (12, 13 and 14) or above.
