[0002] Polyester-cotton refers to the general term for blended fabrics of polyester and cotton, commonly known as "Dacron". It is a common material for making clothes.

[0003] Polyester-cotton fabric not only highlights the style of polyester but also has the advantages of cotton fabric. It has good elasticity and wear resistance in both dry and wet conditions, stable size, small shrinkage, and is upright, wrinkle-resistant, easy to wash, and quick-drying. It cannot be ironed at high temperature or soaked in boiling water.

[0004] In order to improve wear resistance and elasticity, polyester-cotton fabrics usually increase the polyester content, resulting in a decrease in the overall air permeability of the fabric. During wearing, it will absorb sweat from the user's body surface. The continuously produced sweat will gradually block the pores inside the fabric, affecting the subsequent dissipation of sweat. In addition, the moisture absorption and air permeability of polyester fibers are poor, which further affects the circulation of air inside and outside the fabric, making the fabric in a humid state for a long time and prone to bacterial growth. Therefore, a structure is set to solve the problem of bacterial growth due to poor air permeability of polyester cloth.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content
