Technical Field

The utility model relates to a knitted fabric, in particular to high temperature resistant elastic framework knitted fabric.

Background

Because the elasticity of the rubber is large and the elastic modulus is low, the rubber is easy to deform under the action of external force. Therefore, the rubber product must be made of textile material or other materials as a framework to increase the strength and deformation resistance of the rubber product. For example: most rubber products such as tires, adhesive tapes, conveyer belts, transmission belts and the like can not leave the framework material. However, in some special industries, such as a transmission belt made of common textile framework fabric, the product cannot solve the problem that the size of the transmission belt becomes large after long-term use, thereby influencing the use of equipment. At present, a small amount of spandex is added to the skeleton textile fabric in the market, but because spandex has elasticity, the problems of poor heat resistance, easy aging and the like exist, and the long-term use of the product is influenced. Therefore, the development of a skeleton textile fabric with high temperature resistance and good elastic recovery is urgently needed to maintain the long-term stability of the size of a final product, the skeleton textile fabric can be continuously used without influencing the work, and the successful development of the product can generate good social benefit and economic benefit.
