Abstract

PURPOSE: To obtain filament yarns capable of giving hand and touch equal to silk, by combining and entangling two types of ultra-fine polyester filament groups having specific properties and different shrinkages in boiling water.
CONSTITUTION: A filament group (A) is combined and entangled with filament group (B) to give the total denier of 30d or more. The filaments in the froup (A) have a finess per filament of 0.9d or less and a stractural integrity parameter0.025≤ε0.2<0 defined by formula I: (l0 is the length of a specimen 10cm long when a weight of 0.2g/d is applied to its one end; l1 is the length after immersing the specimen under the load in boiling water for 2 min, taking out of the boiling water, and cooling), and an orientation degree in the amorphous region (fa) of 30 W 70% defined by the formula II: (Δn is the birefringence; f is the degree of crystal orientation; Xρ is the degree of crystallinity), and a low shrinkage in boiling water. The filaments in the group (B) have a fineness per filament of 0.9 de or less and a shrinkage in boiling water of 5% or more higher than that of filaments in the group (A).
