Currently, the textile sector is moving towards the development of value-added functional textile products based on customer demand. Therefore, several new finishing techniques have been evolved so far to functionalize the textile substrates. In this context, the microencapsulation technique is one of the advanced technologies which has been used to impart functional properties such as antibacterial activity, aroma, mosquito repellency, UV protection, and thermoregulation to textiles. In microencapsulation, the volatile and non-volatile components can be encapsulated within a thin polymeric layer which causes a slow release of the compound, resulting in long-lasting functional effect. Various active materials, like essential oils, enzymes, drugs, pesticides and vitamins, have been successfully entrapped inside microcapsules made from a variety of polymeric materials. There are interesting reports available in the literature dealing with functionalization of textiles using microencapsulated materials. This review paper covers the fundamentals of microencapsulation, its major techniques, materials involved in microencapsulation and the important research reported in this area. The major essential oils used in microencapsulation and the subsequent functional effects are also reviewed. The present and futuristic research trends in this important area of chemical processing of textiles are presented.

微囊化及其在功能纺织品生产中的应用

当前，纺织部门正在朝着根据客户需求开发增值功能性纺织产品的方向发展。因此，迄今为止已经开发了几种新的整理技术以使织物基材功能化。在这种情况下，微囊化技术是一种先进技术，已被用于赋予纺织品以功能特性，例如抗菌活性，香气，驱蚊性，紫外线防护和温度调节。在微囊化中，挥发性和非挥发性成分可以被囊封在一个薄的聚合物层中，这会导致化合物的缓慢释放，从而产生持久的功能效果。各种活性物质，例如精油，酶，药物，农药和维生素，已经成功地将其包埋在由多种聚合物材料制成的微胶囊中。在文献中有有趣的报道涉及使用微囊化材料的纺织品功能化。这篇综述文章涵盖了微囊化的基础知识，其主要技术，涉及微囊化的材料以及该领域报道的重要研究。还对用于微囊化的主要精油及其后续功能效果进行了综述。介绍了纺织品化学加工这一重要领域的当前和未来的研究趋势。其主要技术，涉及微囊化的材料以及该领域报道的重要研究。还综述了微囊化中使用的主要精油及其后续功能效果。介绍了纺织品化学加工这一重要领域的当前和未来的研究趋势。其主要技术，涉及微囊化的材料以及该领域报道的重要研究。还综述了微囊化中使用的主要精油及其后续功能效果。介绍了纺织品化学加工这一重要领域的当前和未来的研究趋势。
