WOOL-LIKE POLYESTER YARN AND PREPARING METHOD THEREOF

摘要

The present invention relates to a kind of imitative hair polyester yarns of manufacture to have excellent flexibility, heat insulating ability, and bulkyness and light weight and simple production process enter triangular hollow fiber by spin polyester yarn and carry out multi-lobal fibers. In the manufacturing method of imitative hair polyester yarn, the present invention is that a kind of PE yarn for preparing enters multi-lobal fibers, includes the following steps: that the temperature 250-350& deg of triangle doughnut is discharged in thermoplastic polymer from spinning head; C solidifies the yarn of discharge by cooling air to the cross section of yarn is allowed positioned at triangle doughnut is formed, and solidifies yarn mounting surface spray under oil guidance by cooling air and spinning oil; And the yarn handled and spinning oil have been elongated by one or more godets, and are heat-treated the elongate yarn, then wind identical up- coiler. In the manufacturing method of imitative hair polyester yarn, the multi-lobal fibers that the present invention forms fiber wool-like yarn method to manufacture produce triangle doughnut by spinneret, and imitative hair polyester yarn is therefore provided with excellent flexibility, heat insulating ability, bulkyness and light weight, such as wool, simplify production technology simultaneously, solves the problems, such as traditional. ;The 2014 of copyright KIPO submissions
