Hoisting belts are generally used in outdoor, offshore, and port working environments. They are heavily exposed to ultraviolet radiation, resulting in a rapid decrease in strength, easy aging, and reduced service life. In order to improve the service life of the lifting belt, it is necessary to carry out UV resistant treatment on the lifting belt to make it have UV resistant performance. The main function of UV resistant treatment is to reduce the transmittance of ultraviolet rays, mainly through the use of UV finishing agents. Just increase the fabric's reflectivity and absorption of ultraviolet light.

　　UV absorbers can effectively absorb ultraviolet radiation and convert it into heat or low energy radiation energy to release, causing the effect of ultraviolet radiation to disappear. SCJ-966 and HTUV100 are both suitable for anti UV finishing of cotton, polyester, and polyester fiber fabrics. Ordinary fabrics after treatment have good absorption, conversion, reflection, and scattering effects on 180-400nm ultraviolet radiation.

　　UV resistant finishing process flow: mixing reagent solution concentration → soaking and rolling → pre drying → baking. In addition, UV resistant finishing agents have a certain impact on the strength of lifting belts. Therefore, if lifting belts must have UV resistant performance, considering strength, the impact of UV resistant finishing agents can be considered in advance when producing lifting belts. Therefore, if the coefficient of lifting belts was originally 6 times, manufacturers can consider producing lifting belts with a safety factor of 7 or even 8 times, This lifting belt can still meet national or EU standards in terms of strength after being treated with UV resistant finishing agents. The lifting belt has UV resistance function, which can extend its service life under exposure to sunlight. Make the lifting belt itself stronger and more powerful.
