Recently, textiles and their end-of-life management have become the focus of public and political attention. In the European Union the revised waste framework directive defines textiles as municipal waste and stipulates their separate collection by 2025. In the context of these developments, this paper summarises briefly the current state-of-the-art in textile recycling. It is evident that recycling methods are not yet fully developed. This is especially the case with multi-material textiles, which are composed of two or more polymers that are incompatible for recycling. In the practical part of the communication, results are presented which show that enzymatic hydrolysis is a suitable process for recycling textiles made of cotton and polyester. After a complete removal of cotton, the remaining pure polyester fibres undergo a re-granulation and post-condensation step. The so obtained recycled polyester is fed back into the textile processing chain and finally towels are obtained. The main steering parameters of the enzymatic hydrolysis process are described. The study proves that solutions in accordance with the Circular Economy in the textile sector are available but an industrial implementation has not yet been realised.

最近，纺织品及其报废管理已成为公众和政治关注的焦点。在欧盟，修订后的废物框架指令将纺织品定义为城市废物，并规定到 2025 年将它们分开收集。在这些发展的背景下，本文简要总结了纺织品回收的当前最新技术。很明显，回收方法尚未完全开发。多材料纺织品尤其如此，这些纺织品由两种或多种聚合物组成，不适合回收利用。在交流的实践部分，结果表明酶水解是回收由棉和聚酯制成的纺织品的合适方法。完全去除棉花后，剩余的纯聚酯纤维进行再造粒和后缩合步骤。如此获得的再生聚酯被反馈到纺织品加工链中，最终获得毛巾。描述了酶水解过程的主要控制参数。该研究证明，符合循环经济的纺织行业解决方案是可用的，但尚未实现工业实施。
