Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from Taiwan Patent Application No. 103218667, filed on Oct. 21, 2014, in the Taiwan Intellectual Property Office, the content of which is hereby incorporated by reference in their entirety for all purposes.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention discloses a footwear assembly with breathable and wear-resistant woven vamp which applies two warp beam yarn feed rollers of a double beam jacquard to feed the warp yarns made of different materials and having different thread diameters, and the fed yarns are interlaced to form the breathable and wear-resistant woven vamp having diverse internal and external structures, and then the breathable and wear-resistant woven vamp are assembled with the sole structure to form the footwear assembly.
2. Description of the Related Art
Generally, the conventional footwear assembly includes a sole structure and a woven vamp, and shoes, which aim to diverse purposes, are made of different materials to form the vamp. For example, vamp of sport shoe may be made of the materials characterized of anti-stretchability, wear resistance, comfortability, air permeability, compressibility, moisture absorbing and perspiration dissipation, and so on.
One piece woven vamp fabric has been widely applied to manufacture the vamp, and the knitting technique is mainly served as the manufacturing method. However, the vamp fabric made of the knitting technique is still of the shortcomings as follows. Firstly, the used yarns are limited to the specification and size, and the vamp's composition is limited thereto as well. Secondly, only a few kinds of yarns or reinforcement procedure can be applied to satisfy with the requirements of the wear-resistant woven vamp and the tensile strength. Thirdly, the knitted fabrics are mostly monochromatic and piece dyed, and the production speed may be slowed down if the polychrome fabrics are applied. Finally, as the knitted fabrics are of flexibility, the follow-up second process is therefore more complicated, resulting that the related cost increases.
The difference between the knitted fabrics and the woven ones lies in the diverse forms of the yarns in the fabrics. Relative to the knitted fabrics, the woven fabrics are made by obliquely interlacing yarns through warp and weft directions, and the woven vamp made of the woven fabric has the following advantages. Firstly, the woven fabrics have diverse texture compositions and the designed patterns, so that the vamp can thereby be formed more diversely and flexibly. Secondly, as the ideal yarn types can be chose to correspond to the woven fabrics, such that the woven fabrics have better wear resistance, tensile strength, coverage, and so on. Finally, the various yarn types contribute to the choice of the vamp's color.
The tradition weaving machine, however, only applies single warp beam yarn feed roller to feed the warp yarns which are made of monotype material or have single thread diameter, resulting that the current vamp is only made of single layer structure. If producing the fabrics, which have a two-layered structure and are made of different materials, is desired, weaving the two-layered structure or performing a second manufacturing process to the single layer structure is necessary. Such manufacturing process is time-consuming and incapable of being controlled precisely.
In view of the aforementioned description, the inventor of the present invention has been mulling it over and therefore designs a footwear assembly with breathable and wear-resistant woven vamp which aims to improve the shortcomings of the current technique so as to increase the industrial practicability.
