Research progress on the recycling and reuse technology of discarded student school uniforms
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 in-quiry reveals that prevailing recycling techniques continue to grapple with a multitude of challenges,including elevated costs,sub-optimal 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 refine-ment 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.
