Yizheng chemical fiber color-changing polyester masterbatch preparation technology won the award

On November 30, Yizheng Chemical Fiber "photochromic low melting point polyester masterbatch and its preparation method" was listed in the list of winners of the 2022 Science and Technology Innovation Association Science and Technology Innovation Award and won the third prize of scientific and technological innovation invention.

The award-winning achievement is a combination technology of polymerization modification and blending modification, which can regulate the molecular structure and crystallization properties of the polymer according to the performance requirements of the matrix resin of the color-changing material, and develop the formation of modified polybutylene terephthalate (PBT) or polyethylene terephthalate (PET).

Using this as the matrix, the company modified it by blending with color-changing materials to finally produce photochromic low melting point polyester masterbatch
.
Photochromic low melting point polyester masterbatch has the characteristics of good color-changing effect, good stability and good light durability, and can be applied to engineering plastics, films, fiber products and 3D printing materials
.

It is understood that the fiber products prepared by Yizheng chemical fiber discoloration low melting point polyester masterbatch have the advantages of water resistance, fast discoloration and fading speed, and good durability, and have been applied to dazzling color-changing sports shoes and other products
