Steel cord fabric: a structure composed of two or more steel wires, or a combination of strands or strands. The new type of radial tire uses steel cord as the skeleton material, which can be divided into full steel radial tire and semi steel radial tire according to their structure. The former uses steel cord as the skeleton material for both the belt layer and the carcass, while the latter uses steel cord as the skeleton material for the belt layer and fibers for the carcass. Sedans and light trucks generally use semi steel radial tires, while heavy-duty trucks and construction machinery vehicles use all steel radial tires.
Polyester cord fabric: also known as polyester impregnated cord fabric for tires. It is made of strong strands as warp and medium and fine single yarn as weft, and the tire is woven with skeleton fabric. The warp threads are arranged tightly, while the weft threads are arranged sparsely, resembling curtains, hence the name. Curtain fabric is used as the skeleton of rubber products such as tires, allowing them to withstand enormous pressure, impact loads, and strong vibrations. Curtain fabric is an important material that affects the performance and lifespan of tires. The warp thread (also known as curtain thread) bears the load, while the weft thread fixes the position of the warp thread.
Nylon curtain fabric: also known as polyamide curtain fabric/nylon curtain fabric, it currently occupies a dominant position in curtain fabric due to its excellent properties such as high strength, fatigue resistance, impact resistance, and strong bonding with rubber. It is mainly divided into the following two types: nylon 6 cord fabric: large-scale, low-cost, generally used for light truck tires and agricultural tires; Nylon 66 curtain fabric: high strength, high temperature resistance, fatigue resistance, impact resistance and other excellent characteristics, suitable for diagonal load tires, engineering tires, and aviation tires.
Aramid cord fabric: It has the advantages of high strength, high modulus, low thermal shrinkage, good dimensional stability, chemical corrosion resistance, and energy conservation. Aramid cord fabric is made by impregnating twisted aramid unidirectional fabric, which has high strength in the warp 0 degree or weft 90 degree direction. Among them, the warp unidirectional fabric is a four warp broken satin or long axis satin fabric woven from coarse warp and fine weft yarns, used in aircraft tires, military tires, high-end car tires, etc., effectively reducing tire weight and improving tire thermal safety coefficient.
