Product characteristics of polyester industrial silk

June 30,2023

Polyester industrial silk refers to high-strength, coarse denier polyester industrial filament, its denier is not less than 550 dtex.

According to its performance, it can be divided into high-strength and low-elongation type (ordinary standard type), high-mode and low-shrinkage type, high-strength and low-shrinkage type, and active type. The high modulus and low shrinkage polyester industrial yarn has gradually replaced the standard polyester Industrial yarn in tire and mechanical rubber products because of its excellent properties such as high breaking strength, high elastic modulus, low elongation and good impact resistance. High strength and low elongation polyester industrial silk has the characteristics of high strength, low elongation, high modulus, high dry heat shrinkage, mainly used as tire cord and conveyor belt, canvas warp and car seat belt, conveyor belt; High strength and low shrinkage polyester industrial silk due to heat shrinkage, the fabric or woven rubber products have good dimensional stability and heat stability, can absorb the impact load, and has the characteristics of soft nylon, mainly used for coating fabrics (advertising light box cloth, etc.), conveyor belt weft line; Active polyester industrial silk is a new type of industrial silk, it has a good affinity with rubber, PVC, can simplify the subsequent processing technology, and greatly improve the quality of products.


Characteristics and classification of polyester industrial silk:

The yarn quality of polyester silk is not stable than that of rayon, but more elastic. You can cut a rayon thread to test, pull hard, and then relax, and find that the embroidery thread will not shrink; On the contrary, once the pulled polyester yarn is relaxed, it will return to the original length, which sometimes leads to wrinkles, so the online tension adjustment needs to be more accurate. Polyester products are mainly used in covering yarn, socks, yarn, gloves, carpets, curtains and other fields.

According to product performance, polyester industrial filament is divided into three categories: high strength, low shrinkage and high mode low shrinkage.

Various categories of products are broken down as follows:

1. High-strength products are subdivided into:
-- Ultra high strength polyester industrial filament;
-- high-strength polyester industrial filament;
-- high reported medium shrinkage polyester Ding filament;
-- High strength and low shrinkage polyester filament,
2. Low shrinkage products are subdivided into.
-- Medium and low shrinkage polyester industrial filament;
-- Low shrinkage polyester industrial filament:
-- Ultra low shrinkage polyester industrial filament,
3. High mold and low shrinkage products are subdivided into;
-- High mold and low shrinkage polyester industrial filament;
-- High strength, high modulus and low shrinkage polyester industrial filament.
