High-strength and low-extension products, as well as some low-shrinkage products, are mainly used in tire cords, mining conveyor belts, driving triangle belts, lifting belts, PV C coated fabrics, fire hoses, hoses, etc.

The main purpose of the existing products The original intention of the development of polyester industrial filament is to use polyester to replace rayon, nylon 6, nylon 66, etc. as the reinforcing frame material of rubber products. These products include radial tire cord fabric, rubber conveyor belt cord fabric, triangle belt, transmission belt cord, rubber hose cord and cord fabric, etc.

Ordinary radial tire cord fabric standard type (ordinary type) polyester industrial filament, also known as high-strength and low-stretch series. Its important characteristics are low elongation and high thermal shrinkage. Typical specifications.

The cord fabric woven from this kind of industrial silk has the characteristics of low load elongation, but the dry heat shrinkage rate is relatively high. Therefore, when using this type of cord fabric to make tires, the phenomenon of concave joints is obvious. The vulcanized Jinshan oil chemical fiber has a variety of specifications, elongation, dry heat shrinkage, and constant load elongation. After that, it must be inflated and shaped, and can only be vulcanized at room temperature. The vulcanization time is long, the tire scrap rate is high, the production efficiency is low, and the grade of the made tires is low, which cannot meet the requirements of high-performance radial tires.
