摘要

光致变色纺织品是一类功能性纺织品,在紫外光照射下具有增色特性。然而,由于光致变色染料的低水溶性和对纺织材料的低亲和力,通过传统的整理技术将其应用于纺织材料上具有困难。封装技术可用于克服光致变色纺织材料生产中的这些问题。本文是由三部分组成的系列文章中的第三部分,介绍了用喷雾干燥法生产的光致变色染料微胶囊在棉织物上的应用。将光致变色染料微胶囊通过衬垫-干燥-固化工艺应用于棉织物上。在应用和连续洗涤后,评估所得光致变色织物的颜色形成和紫外线透射率。此外,还研究了光致变色织物的抗疲劳性能,并研究了在微胶囊中加入受阻胺光稳定剂的影响。发现即使在20个洗涤循环之后,样品的紫外线保护因子值也为50+。结果表明,在20次紫外线照射循环后,光致变色织物的紫外线防护因子值和色值分别损失了10%和20%,并且在微胶囊生产过程中使用受阻胺光稳定剂化合物提高了光致变色染料胶囊的抗疲劳性。

Photochromic Microcapsules for Textile Materials by Spray Drying—Part 3: Application of Photochromic Microcapsules on Cotton Fabrics
Photochromic textiles, a class of functional textiles, have a color build up feature under ultraviolet light irradiation. However, photochromic dye application onto textile materials by conventional finishing techniques has difficulties due to their low water solubility and low affinity to the textile materials. Encapsulation technology could be used to overcome these problems in the production of photochromic textile materials. This article, which is the third in a three-part series, deals with the application of photochromic dye microcapsules produced by a spray drying method onto cotton fabrics. The photochromic dye microcapsules were applied onto cotton fabrics by a pad–dry–cure process. Color build up and ultraviolet transmittance of the resultant photochromic fabrics were evaluated after the application and consecutive washing. Moreover, the fatigue resistance of the photochromic fabrics was studied and the effects of the incorporation of hindered amine light stabilizers into microcapsules were investigated. Ultraviolet protection factor values of the samples were found to be 50+ even after 20 washing cycles. It was shown that the photochromic fabrics have a loss of 10% in ultraviolet protection factor values and 20% in color values after 20 ultraviolet irradiation cycles and the fatigue resistance of the photochromic dye capsules improved with the use of hindered amine light stabilizer compounds during microcapsule production.
