Structure and production method of a weft-knitted jacquard upper material

Abstract

The invention belongs to the field of textiles and provides a structure and a production method of a weft-knitted jacquard shoe upper material. According to the weft-knitted jacquard shoe upper material, terylen low-melting-point color filaments with skin-core structures are adopted, the meshes, esthetic appearance and air permeability of the shoe upper material are realized by utilizing air-layer jacquard tissues as fundamental tissues, loop accumulation tissues or loop transfer tissues on a dual-way jacquard dual-side loop transfer round weft machine; by virtue of cooperation between colors and structural jacquards, functional sections of the shoe upper material are realized; during aftertreatment, a skin layer is fused at a certain temperature under a certain pressure, so that dual-side weft-knitted jacquard shoe upper fabric loops are mutually glued, then cooled and solidified, so that the shoe upper material with appropriate rigidity and hand feeling is obtained; spandex can also be added, so that the elasticity and the density of the fabric are enhanced. The weft-knitted jacquard shoe upper material is variable in pattern, color and style, beautiful in appearance, portable and flexible, favorable in air permeability and comfort in wear; traditional working procedures of cutting, sewing, bonding and the like for shoe materials are not needed, so that the equipment investment and the labor cost are lowered.

Description

[0001] Technical field: [0002] The patent of the present invention relates to an upper material of sports shoes, in particular to the structure and production method of the weft-knitted jacquard upper material. [0003] Background technique: [0004] The traditional shoe-making industry adopts the sewing process. The patterns on the upper are made of cut leather of different color blocks, artificial suede and other materials. The more complicated the pattern on the upper, the more cumbersome the processing and the higher the cost. . The shoe upper material woven by knitting method, on the one hand, can use textile machines to replace the needle car process to manufacture the shoe upper, reducing labor costs; limit. [0005] Knitted upper material also has the following advantages as the upper material of sports shoes: the production of knitted upper material is different from the production of other leather and rubber shoe materials, which will produce greater pollution, an...

AI Technical Summary

Problems solved by technology

Warp-knitted spacer fabric is the earliest shoe upper material. Due to the weaving characteristics of warp-knitting, meshes of various shapes and sizes can be formed on the fabric, which can meet the requirements of sports shoes for ventilation and comfort. Moreover, the warp-knitting machine has high-speed and efficient Features, high output, but it is difficult to realize jacquard upper due to the arrangement of bars

Flat-knitting shoe upper materials are developing rapidly. Not only can jacquards of various colors and structures be achieved, but also the use of retractable needles and partial knitting can be used to realize integrated molding of shoe upper materials without cutting at all. Constant rotation makes the output lower
