Method for manufacturing elastic woven upper

Abstract

The invention relates to a process for manufacturing elastic woven upper. The process comprises the following steps: A, selecting warp yarns and weft yarns; B, designing the upper, and inputting upper parameters into a shuttle loom; C, starting the shuttle loom, and weaving an initial product; D, performing laser shaping on the initial product obtained in step C so as to process the upper, wherein the initial product in step C comprises an inner woven layer, an outer woven layer, and connecting yarns used for connecting the inner woven layer and the outer woven layer, a setting process is performed between step C and step D, and the initial product is subjected to setting in the setting process by adopting a scutching and setting machine. Decorative patterns are formed by mixing and interweaving covered spandex yarns and twisted threads / high-elasticity yarns on the outer layer of the upper, the stress is balanced due to equal distribution of the yarn texture, and the inner layer of the upper is woven by taking the high-elasticity yarns as the lining, so that the lining is soft. Therefore, the upper has the advantages of high elasticity and is comfortable to wear. Due to the setting process, the upper is difficult to deform and collapse, and an attractive wearing appearance is guaranteed.

Description

technical field [0001] The invention relates to a manufacturing process of an elastic woven shoe upper. Background technique [0002] The traditional shoe upper is generally composed of several parts connected to each other, and the connection method is mainly manual sewing or sewing with a needle car. Such a manufacturing method is time-consuming and labor-intensive, and the aesthetics of the joints of the vamp, or even the entire vamp, cannot be guaranteed due to differences in the manual craftsmanship of the workers. For this reason, in the Chinese invention patent application titled "Manufacturing method of one-piece shoe upper" on the date of application publication No. 2013.02.13, a method of manufacturing a one-piece shoe upper is disclosed, which includes the following steps: (1) obtaining A plurality of parameters of a sample of a one-piece shoe upper; (2) preparing materials according to a plurality of said parameters and loading a plurality of materials on a shut...

Problems solved by technology

[0003] Although the upper of the above-mentioned patent can improve production efficiency, the current woven upper of this type is basically a non-elastic upper, and the product feels stiff and prone to wrinkling. Once the product is used, it is easy to deform, does not rebound, and the surface is wrinkled. bad impression

Moreover, the product does not feel good on the feet, and it is usually necessary to compound a layer of base fabric to reduce the discomfort of friction, and there is a risk of delamination in the way of composite base fabric
