[0098] The present utility model has at least the following advantages by using TPU covered yarn to weave the shoe upper:

[0099] Excellent durability: The abrasion resistance is higher than that of polyester (polyester) fabrics, and it can be used to improve the wear resistance problem in the reverse extensibility jacquard process of warp knitted fabrics;

[0100] Thermoplastic molding; Thermoplastic molding is a common processing method. The TPU material can be thermoformed at a temperature of 130°C - 180°C. This temperature is much lower than that of other materials such as polyester. Compared with traditional polyester, TPU has lower processing temperature requirements, which can effectively reduce production costs and improve production efficiency. In addition, according to customer needs and actual application scenarios, the thermoplastic temperature of TPU can be adjusted arbitrarily, and it can flexibly meet different processing requirements on the premise of meeting the product performance requirements.

[0101] Tear resistance: The TPU covered yarn in the embodiments of the present utility model is a material made by a characteristic addition process. It can evenly cover the surface of the polyester high-strength yarn, thereby endowing it with higher strength and tear resistance. The TPU covered yarn fabric has excellent tensile properties and high tear strength. At the same time, it can also maintain good softness and comfort during use, making it widely used in the fields of clothing, shoe materials, etc.

[0102] Unique hand feeling: Thermoplastic polyurethane can produce knitted upper fabrics with a unique touch;

[0103] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
