摘要

1. The technical field to which the invention described in the claims belongs;The present invention relates to a polyester fiber for manufacturing an embroidery yarn, a method of producing the polyester fiber, and a polyester embroidery spray.;2. Technical challenges to be solved by the invention;A polyester fiber for manufacturing an embroidery yarn excellent in general physical properties and excellent optical properties such as gloss and color developability, a process for producing the polyester fiber, and a polyester embroidery spray are provided.;3. The point of the solution of the invention;Twisting is given to the polyester fiber for fabricating an embroidery yarn having the following properties (bottom yarn), twist is further given to the two or more of the twisted yarns and the yarns are twisted and twisted together and then heat set to have a strength of 2 to 5 g / A polyester embroidery spray having a cutting elongation of 10 to 40%, boiling water shrinkage of 6% or less, and a circularity ratio of 0.55 to 0.85 is produced.
