紫外线具有高能特性,能够伤害人类皮肤和破坏有机化合物,而紫外吸收染料既吸收紫外线,赋予染料抗紫外整理功能,又可提高有机染料的光稳定性,是一类新型的纤维防护功能染料,现已成为染料化学工作者的一个新的研究热点.
Ultraviolet ray has high energy, which can hurt human skin and damage the structures of organic compounds. UV absorption dyes can not only absorb ultraviolet ray and endow themselves with anti-UV finishing property, but also improve their light stability. The UV absorption dyes are a new type of dyes with the function of fiber protection, and they have been a new research hot-spot for dye chemists.
