Description

聚氨酯型高分子紫外线吸收剂
技术领域
本发明是关于一种聚氨酯型高分子紫外线吸收剂，尤指一种可提高日光牢度及具有耐水洗特性的聚氨酯型高分子紫外线吸收剂。
背景技术
一般而言，染整工艺大致可分成染前处理、印染过程及染后处理。更具体地，染前处理例如：烧毛(Singeing)、退浆(desizing)、精练(Scouring)、漂白(Bleaching)、丝光(Mercerizing)、热定型(heat setting)，印染过程如染色、印花，以及染后处理如整理加工(finishing)。染前处理的目的在于去除纱线或织物上的天然杂质、以及来自纺织过程的浆料、助剂和沾污物，以免影响后续的印染作业。而染后处理则是为了增加织物的使用性或特殊性能(例如：提升色牢度、改善外观、改善手感、防缩、防皱、防静电、防火、防水、拨水、拨油等)，其会随着织物材质及需求的不同而有不同的处理方式。
为了避免织物因日光(紫外线)曝晒而分解，通常在染后处理的步骤中，添加日光牢度增进剂(例如，紫外线吸收剂、光安定剂等)，以维持织物的使用寿命。目前已有各种材料被应用以增加产品的日光牢度，例如含有具紫外线吸收功效的氧化锌(ZnO)及二氧化钛(TiO2)的溶液、苯并***衍生物、二苯甲酮衍生物等，然而，部份材料因亲水性不佳，仅适用于特定种类纤维及染料；部份材料虽亲水性佳，但牢度不佳；部分材料亦有附着牢度差、不耐水洗等缺点；以及部分材料使用时需伴随大量有机溶剂或添加界面活性剂，因而极不符合环保需求。尤其，现今日光牢度增进剂经水洗后的耐UV效果大幅降低，故耐水洗性差而使用寿命较短。
有鉴于此，为符合产业的需求，仍亟需研发具良好的水分散性、耐水洗性、环保、且能广泛应用于多种材质目标物的日光牢度增进剂。
