Description

Technical Field

[0002] Tire cord fabric is a skeleton fabric used in rubber products, woven with strong strands as the warp and medium- and fine-count single yarns as the weft. Its fiber materials are primarily chemical fibers such as polyester and nylon. As the skeleton material for rubber products, tire cord fabric is widely used in conveyor belts, automobile tires, and other fields. However, due to the low polarity, high crystallinity, and chemical inactivity of chemical fiber molecules, their adhesion to rubber is poor. To improve the adhesion between chemical fiber fabrics and rubber, they need to be pretreated.
