反应性防紫外线整理剂UVDHA的研究

Research on reactive anti-uv finish UVDHA

反应性防紫外线整理剂UVDH是适合于纯棉织物防紫外线整理的紫外线吸收剂,它对UVB(280￣315 nm)波段的紫外线有强烈的吸收作用,但对UVA(315￣400 nm)波段的紫外线吸收较少.在UVDH中加入合适的改进剂A后复配成UVDHA,它能够大大降低UVA的透过率,从而使织物的紫外线辐射防护系数UPF有明显的提高.此外,还研究了整理剂对染色织物色光的影响及织物整理效果的耐久性.

UVDH, a reactive finishing agent for uv-proofing, was suitable for cotton fabrics. It absorbed strongly the UVB light （280-315 nm）, but absorbed little the UVA light （315-400 nm）. A suitable improving agent A was added in UVDH to formulate UVDHA, which lowed markedly the UVA penetration, and increased remarkably the anti-uv radiation protection coefficient of the fabrics. The effect of the finish on fabric shades and the durability of the finishing effect were also studied.
