Abstract

The invention discloses a color-changing sunscreen fabric and a preparation method thereof. The preparation method comprises the following steps that a collagen and chitosan blended membrane is taken as an outer layer membrane, azodihydric alcohol grafted polyurethane is taken as an inner layer membrane, tea polyphenol is added as a connecting agent when an inner layer microcapsule is combined with the outer layer membrane, and dodecyl amine and rosolic acid are taken as an inner core to prepare microcapsules; zinc hydroxide is added during padding-steaming finishing, and a cross-linked structure accompanied by electrostatic adsorption is formed on the surfaces of the cotton fibers and the microcapsules, so that the microcapsules are firmly combined on the surfaces of the cotton fibers; a novel benzophenone photoinitiator is prepared as a finishing agent, the polyurethane fiber is subjected to padding-steaming finishing, and a main chain of the novel initiator can be wound on the surface of the polyurethane fiber, so that the fabric obtains the washable performance while obtaining the sun-proof and ultraviolet-proof capability; and padding-steaming finishing is carried out twice to obtain the fabric with color-changing and sun-screening properties.

Description

technical field [0001] 本发明涉及面料领域,具体为一种变色防晒面料及其制备方法。 Background technique [0002] 在工业飞速发展的今天,各类化合物的使用逐年增多,臭氧层的含量严重减少,紫外线的透过量与日俱增,这必将会给皮肤造成越来越多不可逆转的伤害。随着人们的保健意识提高,人们对于防晒的追求不再局限于防晒化妆品的使用,将防晒需求转移到服装上。 [0003] 对于防晒面料的研究并不少见,但既能防晒有可以变色的面料研究甚少。所以研究既能够防晒又具有变色趣味的面料是非常有发展前景的。因此,制备一种变色防晒面料是非常有必要的。 Contents of the invention [0004] 本发明的目的在于提供一种变色防晒面料,以解决上述背景技术中提出的问题。 [0005] 为了解决上述技术问题,本发明第一方面提供如下技术方案:一种变色防晒面料,其特征在于,包括以下重量份数的原料: [0006] 50~100份棉纤维、50~100份聚氨酯纤维、15~30份氢氧化锌、5~10份聚氨酯、5~10份偶氮二元醇、5~10份二苯甲酮单体、10~20份壳聚糖、10~20份胶原蛋白、10~20份新型二苯甲酮光引发剂、5~10份十二烷基胺、5~10份玫红酸。 [0007] 优选的,所述偶氮二元醇是以N,N-二羟乙基苯胺为原料制得偶氮二元醇。 [0008] 优选的,所述二苯甲酮单体为含有两个两个活性羟基的4-(2,3-二羟基)丙氧基二苯甲酮。 [0009] 优选的,所述新型二苯甲酮光引发剂二苯甲酮单体与二异氰酸酯进行逐步聚合,得到侧链为二苯甲酮,主链含共引发剂胺的聚氨酯型高分子光引发剂。 [0010] 本发明第二方面提供:一种变色防晒面料的制备方法,其特征在于: [0011] 工艺流程为: [0012] 变色微胶囊制备,新型二苯甲酮光引发剂制备,第一次浸轧-汽蒸整理,第二次浸轧-汽蒸整理。 [0013] 优选的,包括以下具体步骤: [0014] (1)变色微胶囊制备; [0015] (2)在氮气的保护下,将3份二异氰酸酯和5份N,N-二甲基甲酰胺加入到有磁力搅拌的三口烧瓶中,搅拌至完全溶解,将0.5份二苯甲酮单体与5份N,N-二甲基甲酰胺溶液...
