It is made by specially-processed nanoscale ultraviolet-resistant agent dispersing into melt PET in the spinning process. Uniform distribution of ultraviolet-resistant agent enables the fiber and the fabric not only to reflex ultraviolet radiation but also to transfer ultraviolet energy to thermal energy or other harmless low-energy form and accordingly release or consume it. Based on the structure and color of the fabric, it can resist UV-A and UV-B permanently with UPF value over 50.

Ultraviolet screening factor reach 92%
