UV rays from natural or artificial sources are one of the dangerous carcinogens, and prolonged exposure to UV radiation can induce skin aging and even skin cancer. Therefore, the use of UV protective textiles in industrial work areas with significant UV hazard is essential. Colloidal materials have excellent UV blocking properties due to their unique structure and properties. Alfa Chemistry provides customers with UV protective textile solutions incorporating colloidal materials by studying the UV blocking mechanism of colloidal materials.

Research and Practice of Colloids in UV Shielding Fabrics

Traditional textiles have deficiencies in protection against external environmental hazards. With the development and advancement of technology, the application of colloidal materials in the development of protective textiles has increased rapidly. Various types of colloidal materials have been used to produce textiles with additional functions, such as flame retardant textiles, antibacterial textiles, UV protective textiles, self-cleaning textiles, industrial textiles, etc. Colloidal materials possess properties such as high specific surface area, improved functionality, and high surface energy, which can interact better with textile materials, providing fabrics with better functionality and better durability. For example, bleached cotton fabric treated with 2% ZnO colloidal particles (40 nm particle size) in an acrylic binder showed 75% UV blocking. And colloidal TiO2 has been widely used as a UV blocker in the manufacture of UV protective textiles.

Colloidal materials as additives for UV-protective textiles are a promising area of research. Alfa Chemistry enables in-depth study of the interaction between colloidal materials and textiles and develops various methods for incorporating colloidal materials into textile matrices. We are also able to study the durability and toxicological properties of the UV protection properties of textiles treated with colloidal materials using various detection techniques.
