Abstract:

Limited by the technology and market acceptance, a large amount of waste textiles were treated and they were either buried or incinerated, causing both resource waste and environmental pollution. In order to improve the high-value recycling of waste textile resources in our country, this paper reviews summarizes the development of waste textile recycling technology and technical difficulties, introduces the recycling status of waste texties at home and abroad, with special attention paid to the research and development of domestic waste textile recycling technology in recent years. Comparing among different recycling technology routes, it is believed that chemical recycling method is a better solution for the high-value reuse of waste textiles, especially through the glycol alcoholysis regeneration route. With the improved awareness of domestic environmental protection and relevant policy guidance, the high-value recycling market for waste textile recycling is predicted to gradually expand. It is advised that related domestic enterprises should develop corresponding arrangements as soon as possible, focusing on the industrialization process of related technologies, and realize the resource utilization of waste textiles as soon as possible.

Key words: waste textile, recycling technology, high-value recycling, chemical method, glycol alcoholysis regeneration route
