Abstract

See full text

A different shrinkage composite yarn and preparation method. The modified polyester is spun with a porous spinneret to produce a different shrinkage composite yarn, and the spinneret holes on the porous spinneret are arranged in an elliptical arrangement. The different shrinkage composite yarn is obtained by winding modified polyester POY yarn and FDY yarn, network recombining, and coiling them. The preparation method of modified polyester is as follows: terephthalic acid reacts with ethylene glycol to produce ethylene terephthalate. The modified polyester is obtained by the reaction of terephthalic acid with branched diol. The fiber of the invention has good properties and the deviation rate of fiber density. The CV value of breaking strength is ≤4.0%, the CV value of elongation at break is ≤8.0%, the CV value of coefficient of variation of coiling shrinkage is ≤8.0%.
