摘要/Abstract

摘要：

国内废旧纺织品资源受技术、市场接受度等影响,大量被当作垃圾掩埋或焚烧,造成资源浪费和环境污染。为提高我国废旧纺织品资源高值化循环利用水平,总结了废旧纺织品循环再生方法和技术难点,介绍了国内外废旧纺织品回收现状,重点分析了国内近年来废旧纺织品回收技术进展,并对比了不同回收技术路线特点。认为化学法回收是废旧纺织品回收高值化利用的较优方案,尤其是乙二醇醇解法再生路线;随着国内环保意识的逐渐加强和相关政策引导,废旧纺织品回收高值化再生市场将逐渐扩大,国内相关企业应尽早开展战略布局,着眼于相关技术的产业化进程。

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
