摘　　要：为积极促进废旧学生校服的高值化回收再利用,本文聚焦废旧学生校服的回收再利用技术,按照面料组分进行分类,分别对单组分面料、涤棉混纺面料、氨纶混纺弹性面料的回收方法进行论述分析。分析表明:目前回收技术仍然存在成本高、效率低、再生产品质量参差不齐、环境污染等问题,且针对多组分废旧面料回收缺少研究。本文提出:建议未来废旧学生校服的回收技术关注回收纤维时所使用的试剂的循环利用问题;建议细化废旧校服面料分类,进行差别化回收再利用,形成较为成熟的回收顺序,最大化提升各纤维组分的回收率。In an effort to actively propel the valorization of discarded student uniforms through efficient recycling and reuse,this study centers its attention on the technologies employed for the recuperation and repurposing of such garments,classifying them according to their constituent textile materials.It undertakes a rigorous examination and dissection of the retrieval methodologies applicable to mono-component textiles,polyester-cotton blend fabrics,and elastane-enriched,mixed-fiber elastic textiles.The inquiry reveals that prevailing recycling techniques continue to grapple with a multitude of challenges,including elevated costs,suboptimal efficiency,a spectrum of regenerated product quality,and detrimental environmental impacts.Furthermore,it underscores a conspicuous dearth of scholarly inquiry into the recycling of multi-fiber composite waste textiles.This study advocates that the trajectory of future advancements in recycling technologies for discarded student uniforms should be steered towards the paramount concern of fostering the cyclical utilization of reagents employed during the fiber extraction process.It further propounds the refinement of waste uniform fabric categorization for discriminatory recycling and reuse,thereby engendering a meticulously structured and mature recycling hierarchy,ultimately optimizing the recovery rates of individual fiber constituents.
