Abstract

PURPOSE: A ternary-system conjugate fiber in which two polymers different in shrinkage are bonded like a bimetal, they are divided into plural sections by the third polymer, then, the three polymers are split or patially dissolved to produce a mixed yarn containing shrinking filaments and unshrinking filaments.
CONSTITUTION: In the cross section of the fiber, two kinds of polymers A and B, which are compatible with each other and different in shrinkage, are bounded like a bimetal and they are divided by a polymer C, which is poor in compatibility of different in solubility, into plural zones. The polymer C is exposed to the surface of the fiber and at least one of polymers A and B is included as the core parts. This conjugate fiber is produced using a spinneret block consisting of two plates 3 and 4 on the spinneret 1 and the bottomed cylinder of reversed T-shape 5 which is set so as to come through coaxially to the spinning nozzle 2.
