PURPOSE:To obtain polyester fabric having fibril on the whole face of the fabric, bulkiness of silk, natural appearance not found in the conventional fabric for clothing and handle of downy touch. CONSTITUTION:Conjugate yarn consisting of at least two kinds of polyester filaments yarns wherein the difference between alkali dissolution rate constants k1 and k2 is (2,5-6.0)X10<-8>cm/sec, the smaller alkali dissolution rate is >=3.0X10<-8>cm/sec, the k1 yarn is yarn having high shrinkage and has >=8% shrinkage percentage in boiling water, the difference in shrinkage percentage in boiling water between the k1 yarn and the k2 yarn is >=5% and the k2 yarn is yarn subjected to relaxation heat treatment, containing a small amount of polyoxyethylene glycol is woven or knitted and the k2 yarn is mainly fibrillated by alkali treatment in a dyeing and processing process to give fabric. |
