Low-elasticity light-net interlaced yarn air-jet weaving method for environment-friendly automobile decorative cloth

Abstract

The invention relates to a low-elasticity light-net interlaced yarn air-jet weaving method for an environment-friendly automobile decorative cloth and belongs to the technical field of spinning. A heald frame of a loom is adopted for horizontal upward movement for 4-7 mm to ensure that an opening of a small shed is clear; an auxiliary nozzle is adopted for moving downward for 2 mm to prevent warpyarn from being hooked by the auxiliary nozzle; the opening amount of a warp shed is increased by 60%, the opening time is prolonged by 14%, the friction of weaving yarn is reduced, the tension changeof the warp yarn during opening and closing movement is reduced, and breakage of the warp yarn is avoided; the winding tension is reduced by 20%, and smooth winding is realized; through the on-machine movement of large opening of the warp yarn, low-wear weft introduction, small-tension beating-up, closing and small-tension winding, interweaving of the warp yarn and weft yarn of low-elasticity light-net interlaced yarn is realized. The method changes an air-jet weaving process flow of conventional automobile decorative cloths, the mode of direct weaving, drawing-in and warp knotting and special process weaving is adopted, the procedures of reeling, double twisting and sizing are eliminated, the flow is reduced, energy is saved, the consumption is reduced, the sizing pollution is avoided, and a final product satisfies environmental protection standards.

Description

technical field [0001] The invention relates to an air-jet weaving method of an environment-friendly automobile decorative cloth with a low-elasticity light mesh network yarn and belongs to the technical field of textiles. [0002] technical background [0003] Network DTY yarn is processed by DTY yarn through network nozzle under the action of compressed air. It has a good effect in improving the aurora effect and waxy (resin) feeling of DTY yarn, and brings some unique styles to DTY yarn. . According to the current market situation, according to the network degree and network fastness, there are weak network wires, light network wires, medium network wires and heavy network wires. In general, the best effect can be achieved by producing the network yarns of various properties by the corresponding network nozzles, that is, the light network yarns are produced by the light network nozzles, and the heavy network yarns are produced by the heavy network nozzles. The heavy net ...

Problems solved by technology

It is obvious that the application is to solve the problem that each monofilament in the filament is easy to be broken, snagged and fluffed, and it is difficult to weave by twisting the filament; but this method requires additional processes and increases energy consumption, especially twisting The back filaments are tightly entangled, the style of the produced fabric is quite different from that of untwisted filament fabrics, and the air permeability and softness are reduced
