uv protective finishing agent scj-966 consists of uv absorbers and reflectors. the former can absorb the high-energy uv rays and convert them to low thermal energy or short-wave electromagnetic waves. therefore the absorbers diminish the hazard of uv rays to humans and fabrics. the reflectors can enhance the reflecting and scattering powers of fabric against uv rays. the agent features asepsis, incombustibility, non-explosion, is safe to the human body as well as incurring no impact on shade, strength, handling and permeability of fabrics. testing carried out by australia test unit and several authoritative organizations proves that fabric treated with this agent can shield uv radiation, the upf of cotton fabric treated by scj-966 can be reached up to upf 50+.
