Title:
POLYESTER FIBER
Document Type and Number:
WIPO Patent Application WO/2015/029316
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the spinnability and productivity and increase the tensile strength of a polyester fiber that contains poly(3-hydroxybutyrate-co-3-hydroxyhexanoate). In the present invention, by spinning a polyester resin that contains poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) at a high take up speed, it is possible to improve the spinnability and productivity and increase the tensile strength of the polyester fiber.
