(1) Common technique method
The anti-UV arrangement craft for Fiber and textile have relations with finishing agent’s character and product’s final usage. common technique method is high temperature and high pressure suction method/ ordinary pressure suction method/ padding methods/ coating method/ printing method etc.
(2) Microcapsulary technique
The microcapsulary technique is wildly used in industry field, which is one special packing method, the substance on the capsule can be solid atom or liquid or bubble. Put the UV absorption agent on the capsule, which adsorbed on the garment, during adsorption ,it ‘s being friction, the outside of the capsule being crack, up to slow-release effect for anti-UV arrangement agent, can resist long time UV radiation.
(3) Sol rubber jelly technique
Sol rubber jelly technique is metal alkoxy compound as precursor on the mild condition hydrolytic condensation sol rubber, being though volatilization or heat treatment, make the sol rubber transfer to oxide sol rubber of net structure process. Using silica or other metal oxide nanometer jelly treatment textile, can form one layer multi-hole structure oxide xerogel on textile surface, however primary nanometer sol rubber particle forming three D net construction. Nanometer sol rubber easy to be formed by chemical or physical modified, can improve fabric’s services performance drastically, make it multi-functionalization, meanwhile anti-UV performance better.
(4) Foam method
Foam arrangement craft can replaced by common padding craft treated on fabric being anti-UV arrangement. This craft decreased the fabric take-up, energy-saving and cost-reducing effect remarkable, and increase production speed, saving dyeing and decrease wastewater discharge, conform to nowadays green dyeing and finishing development direction.
(5) Supercritical carbon dioxide
Since 1988 textile supercritical fluid dyeing ‘s leader patented invention, supercritical carbon dioxide liquid in textile industry ‘s applied research mainly concentrate on dyeing aspect, especially using on disperse dyes polyester fiber. It is discovered, when use level be 1.0% benzotriazole UV adsorption agent UV-234, pressure 20MPA,when the treated temperature is 120℃(393 K), poly fiber’s degree of opening is maximum, UV agent adsorption also much more, UPF value can reach 60 and fiber physical performance better.
According to textile anti-UV mechanism, nano-photocatalyst mainly as UV reflect agent(shielding agent), through reflect incidence UV, up to anti-UV radiation’s purpose.
