UV Protection Finishing for Outdoor Textiles
topic
UV protection finishing applies UV-absorbing benzotriazole, triazine, or titanium dioxide compounds to textile substrates through exhaust bath at 1 to 4 percent on weight of fabric or padding, increasing the fabric ultraviolet protection factor measured by spectrophotometric transmission measurement and calculated as UPF value, with UPF above 50 providing excellent protection and minimum UPF 15 required for any UV protection marketing claim.
Role
Provides the ultraviolet radiation protection required for outdoor apparel and technical textiles by applying UV-absorbing compounds that reduce the UV transmission through the fabric to the wearer's skin, with UPF finishing enabling cotton fabrics with inherently low UV protection from low cover factor to achieve UPF 50 plus ratings that qualify for sun protective clothing certification for beach, outdoor sport, and UV-sensitive medical patient applications.
