[0002] As people's demand for protection and comfort increases, functional clothing fabrics have been widely used in the market, especially fabrics with UV resistance and breathability are more popular among outdoor enthusiasts. Existing UV-resistant fabrics usually improve the protection effect by applying UV-resistant coating on the fiber surface or adding functional materials. At the same time, breathability is also an important indicator that cannot be ignored in fabric design. However, while improving the anti-UV effect, how to maintain the breathability of the fabric and ensure its comfort in actual application has become a major challenge in technology development.

[0003] Although existing anti-ultraviolet fabrics have been improved in some aspects, they still have many problems, such as short-lasting anti-ultraviolet performance, poor air permeability, complex process, insufficient environmental protection, etc. In addition, the antibacterial properties of existing fabrics are often ignored, resulting in the problem of bacterial growth after long-term wearing.
