The tire cord cloth is in the inner layer of the tire, which is a kind of cloth lined inside the tire to protect the rubber and resist tension.
The rubber-impregnated tire cord fabric exists in the tire carcass, which constitutes a single-layer or multi-layer rubber-coated cord part of the tire skeleton, and requires good impact resistance and flex resistance. The part where the tire carcass cord is wound and combined with the rim is composed of bead steel wire and rubber.
the cord fabric is only used on semi-steel radial tires, but not on all-steel and bias tires.
The requirements for tire cord are:
1. High strength and initial modulus;
2, heat resistance;
3, fatigue resistance;
4, the structure is stable;
5, can be bonded with rubber.
Extended information:
Tire cord fabrics mainly include nylon cord fabric, polyester cord fabric, viscose cord fabric and steel cord fabric. With the continuous improvement of tire meridian rate, the general trend is that the demand for polyester industrial yarn is increasing and the output of polyester industrial yarn is increasing.
The cord fabric is mainly used in the skeleton materials of tires and belt products. Therefore, the cord fabric is required to have high strength, fatigue resistance, impact resistance, as low as possible elongation, good heat stability, good adhesion to rubber, aging resistance and easy processing. The commonly used curtains in rubber industry include nylon curtain, polyester curtain, aramid curtain and steel wire curtain. When selecting the cord fabric, the cord fabric should be divided into different specifications according to the structure of the product and the function of the cord fabric.
Cord fabric is characterized by thick warp, high density, thin weft and sparse density. According to plain weave, the warp bears all the load of the product, and the weft only plays the role of connecting the warp, and keeps the warp evenly arranged so as not to be disordered.
