The invention discloses a method for manufacturing different-shrinkage polyester low-stretch yarns, which comprises the following steps: s1, preparing modified polyester; s2, preparing modified polyester master batch; s3, preparing the differential shrinkage polyester low stretch yarn; and S4, post-treatment of the different shrinkage polyester low stretch yarn. The method for manufacturing the different-shrinkage polyester drawn textured yarn can prepare single-component different-shrinkage fibers, and the prepared different-shrinkage polyester drawn textured yarn has the advantages of high dye-uptake rate, uniform dyeing and good shrinkage performance. |
