High-modulus Recycled Polyester Industrial Yarn

Reasons for recommendation

Made from 100% recycled polyester material, the fiber has high

strength and good dimensional stability, providing sustainable fiber

raw material support for automotive rubber frame products such as

builder fabrics and coil hoses, as well as ropes and frame materials.

Preparative technique

The fiber is prepared by high-oriented spinning technology and

low-draw post-treatment process using recycled polyester chips

from solid state polycondensation technology.

The downstream application guidance

Co-twisting: Two or more of its strands can be twisted into cords, and it can also be mixed with other fibers into coil hoses, ropes, among others.

Weaving: The fiber is mainly arranged by a certain warp density in a plain structure to make cord fabrics and gray cloth; it can also be used for the development of webbing and other cloth covers.

Impregnation: It can be made into cord fabrics by specific impregnation treatment and certain thermal stretching and setting process, and can be vulcanized and bonded with rubber.
