Synthetic textile production is a major contributor to global waste growth, a phenomenon exacerbated by population growth and increased consumption. Global fiber production is expected to reach 147 million tons by 2030. New insights into recycling solutions are being developed. For example, progress has been made in recycling fibers such as polyester, including polyethylene terephthalate (PET), through the use of enzymes that can break specific bonds and return the material to its original state. However, this process must be carried out according to the nature of the polymer in question. In addition, the mixing of different synthetic fibers and the use of dyes make it difficult to develop a complete recycling process that separates the fibers and returns them to their original raw material. This review focuses on two types of fibers widely used in the textile industry, Nylon or polyamide (PA) and elastane (Spandex or Lycra), and explores the challenges and opportunities associated with their recycling.
合成纺织品生产是全球垃圾增长的主要促成因素，人口增长和消费增加加剧了这一现象。预计到2030年全球纤维产量将达到1.47亿吨。人们正在开发关于回收解决方案的新见解。例如，在通过使用能够断裂特定化学键并使材料恢复到原始状态的酶来回收聚酯等纤维方面取得了进展，包括聚对苯二甲酸乙二酯（PET）。然而，这个过程必须根据所涉及聚合物的性质来进行。此外，不同合成纤维的混合以及染料的使用使得开发一个完整的回收过程变得困难，该过程要分离纤维并将它们恢复到原始原材料状态。本综述聚焦于纺织工业中广泛使用的两种纤维，尼龙或聚酰胺（PA）以及氨纶（斯潘德克斯弹性纤维或莱卡），并探讨与其回收相关的挑战和机遇。
