People begin to pay attention to whether the textile clothing has natural antibacterial or bacteriostatic function, and whether it is suitable for direct contact with the skin and long-term wearing. This trend reflects the high concern of consumers for the safety of textiles and the pursuit of healthy life quality. People hope to reduce the health risks such as skin allergy and infection by choosing textiles with antibacterial and bacteriostatic properties, so as to improve the comfort and safety of daily life.

3. The water wash resistant, anti-deformation fabric according to claim 1, wherein, In step (1), the first pre-drying is at 80-100°C for 3 min, and the first baking is at 90-115°C for 3 min.

4. The waterproof and oil-proof fabric according to claim 1, characterized in that, In step (6), the second pre-drying is at 80-100°C for 4 min, and the second baking is at 100-130°C for 3 min.
