The textile industry can benefit from the use of microcapsules, both adding value to products through the production of technical or functional textiles and improving the processes in the production chain. Some applications have been widely explored in academic research, but many are not feasible for use in industrial scale. Thus, the aim of this study was to develop consistent and efficient methodologies for the encapsulation of active compounds commonly used in the textile industry, employing materials which are viable for large-scale application. In this study, polyurethane-urea microcapsules were formulated by interfacial polymerization and encapsulated with C.I Disperse Blue 60 for the dyeing of polyester fabric without the use of dispersing agents and other auxiliaries. The dyeing was carried out in a high temperature dyeing machine with a very simple dyebath, in which there are only dissolved dye molecules, microencapsulated dyes and the fabric. Additionally, the dyebath wastewaters were reused on a further dyeing as 100% bathwater and mixed with 50% distilled water. Colorimetric measurements show excellent colour removal in both samples.
纺织工业可以从微胶囊的使用中受益,既能通过生产技术或功能性纺织品为产品增值,又能改善生产链中的工艺。一些应用在学术研究中已得到广泛探索,但许多在工业规模上不可行。因此,本研究的目的是开发一致且高效的方法,用于封装纺织工业中常用的活性化合物,采用适用于大规模应用的材料。在本研究中,通过界面聚合法制备了聚氨酯-脲微胶囊,并将其用C.I.分散蓝60进行封装,用于聚酯织物的染色,无需使用分散剂和其他助剂。染色在高温染色机中进行,染浴非常简单,其中只有溶解的染料分子、微胶囊化染料和织物。此外,染浴废水作为100%的浴水用于进一步染色,并与50%的蒸馏水混合。比色测量表明两个样品的脱色效果都非常好。
