This public case uses the dense layer transformed from the base cloth layer to try to improve the structural strength of artificial leather. However, the design improvement of this dense layer is limited. The base cloth made by melt-blown or spun-bonded is still a non-woven fabric. There is no traditional needle-rolled non-woven fabric process to make fibers rectify to improve strength, but only a stacked fiber mesh structure, which still cannot solve the problem of poor physical properties and dimensional stability of mesh non-woven fabrics
[0006] Therefore, there is an urgent need to develop a novel fiber structure in the art to overcome the disadvantages of the above-mentioned artificial leather's poor physical properties and dimensional stability

Abstract
The present invention relates to a fiber-containing structure, a method for manufacturing the same and uses thereof, the fiber-containing structure comprising an interwoven and welded base material and a welded elastomer layer, and at least one part of the base material and the welded elastomer layer are welded to each other. The invention also relates to a method for manufacturing the fiber-containing structure and a shoe structure containing the fiber-containing structure.
Description
technical field [0001] The present invention relates to a fiber-containing structure, in particular to a fiber-containing structure applicable to shoemaking, its manufacturing method and its application. Background technique [0002] Artificial leather is very important in the textile industry. Artificial leather is widely used in fields such as furniture and shoemaking, especially upper leather. [0003] For example, the current shoe upper material usually includes an inner lining and artificial leather or mesh as the surface layer, and then hot-melt adhesive is used on the surface to bond polyurethane to impart colorful surface changes, and the finished shoe can be made. But this process is complicated, and when the surface layer is made of artificial leather, it has good water resistance, but poor air permeability; when the surface layer is made of mesh cloth, it has good air permeability, but not waterproof. [0004] In order to improve this complicated process, the ind...
