Abstract

The invention aims at providing industrial canvas. Warp yarns and weft yarns adopt activated polyester industrial filaments, wherein an external layers of polyester industrial filaments are processed by epoxy compound activation oil agents; density of warps is 136 warps / cm; density of wefts is 56 wefts / cm; the warp yarns and the weft yarns adopt activated polyester industrial filaments; the filaments have the advantages of high modulus, high orientation and good size stability under high temperature; the external layers of the polyester industrial filaments are processed by the epoxy compound activation oil agents, consequently, the performance of high modulus and low shrinkage of the polyester yarns can be ensured; impregnation through one bath process is used in a subsequent impregnation process, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the field of fabrics, in particular to a canvas for industrial conveyor belts. Background technique [0002] The performance of fibers is the basis of the performance of canvas for conveyor belts, and the physical and mechanical properties of fibers determine the performance and processing technology of products. The transportation distance of the general conveyor is usually relatively long, so the purchase cost of the conveyor belt accounts for an increasing proportion of the purchase cost of the enterprise. Due to the limitation of the price of upstream raw material nylon industrial filament, the price of industrial canvas is relatively high. Therefore, the search for conveyor belt skeleton materials with superior performance and reasonable price has attracted more and more attention from conveyor belt manufacturers. Under the premise of not affecting the conveying efficiency, reducing the production cost of the conveyor be...
