聚醚/二苯甲酮类紫外吸收基聚硅氧烷应用性能研究

对有机硅抗紫外线整理剂侧基聚醚/二苯甲酮类紫外吸收基聚硅氧烷(PE-PUVSi)在100%棉布上的应用性能进行了研究.结果表明:经PE-PUVSi整理后的棉织物具有明显的抗紫外效果,柔软性能有很大改善.研究还发现,PE-PUVSi中二苯甲酮紫外吸收基(UV)质量分数由4.67%增至26.58%时,整理后织物的紫外光透过率由71.0%降至38.1%,但整理后织物的吸湿性下降,白度变略有下降.柔软性能在UV质量分数为19.29%时达到最好,此时紫外光透过率为43.6%.

Application of polysiloxane with both polyether and derivative of benzophenone groups

Study the character and performance of 100% cotton treated by a novel polysiloxane textile finishing agent the polyether(PE)/benzophenone derivative(UV)side groups polysiloxane(PE-PUVSi).From the result we found the pure cotton treated by PE-PUVSi had UV absorb ability and the cotton was more softer.And we also found,the ration of UV group rose from 4.67% to 26.58%,ultraviolet transmittance descended from 71% to 38.1%,but finished cotton hydroscopicity and whiteness puny descended.When the ration of UV group was 19.29%,the soft character of the textile was best and ultraviolet transmittance was 43.6%.
