摘要

PURPOSE: To obtain the subject yarn suitably usable for women's clothings capable of expressing suitable bulged feeling and soft touch. CONSTITUTION: The objective yarn contains a self-extensible polyester multifilament yarn A having <=0.95 crystal orientation (fc(A)), >=0.04 to <=0.13 ratio of amorphous orientation (fa(A))/crystal orientation (fc(A)), >=1.1 to <=2.3 ratio of amorphous orientation (fa(A))/birefringence (Δn(A)) and <25.0% crystallinity (χc(A)).
