摘　　要：为净化环境、减少垃圾排放、节约资源和更大程度开发蚕丝纤维的价值,文章综述了废旧蚕丝的回收再利用方法及其主要应用。分析了废旧蚕丝回收再利用的价值,归纳了废旧蚕丝纤维和茧丝绸业丝胶蛋白的回收方法及其主要再应用领域,并对废旧蚕丝纤维回收再利用存在的问题及研究方向进行总结与展望。分析认为:利用化学回收法对废旧蚕丝纤维进行回收,通过提取丝素材料再利用可以有效减少资源浪费;目前对废旧蚕丝纤维的回收再利用还存在利用率较低及开发丝素材料的新技术不成熟等问题,基于这些问题对今后该领域的主要研究方向提出了建议。Silk,as a highly valuable natural protein fiber,is deeply loved by consumers in the textile and clothing industry due to its advantages of elegant wearing,soft touch,and good breathability.In addition,its excellent biocompatibility,biodegradability,and mechanical strength make it have great potential in the biomedical field.In China,a large amount of waste silk,cocoons,and waste liquid are generated during the silk reeling process every year.Meanwhile,with people regularly updating their clothing,home textiles,and other lifestyle habits,a large amount of waste silk products are quickly generated.The recycling and reuse of waste silk products,cocoons,silk fibers,and sericin protein not only promote resource conservation and reduce pollution and carbon emissions,but also play a crucial role in the supply of textile industry raw materials and alleviating resource pressure.The article summarizes the recycling and reuse methods of waste silk and their main applications in order to purify the environment,reduce garbage emissions,save resources,and maximize the value of silk fibers.There are three common methods for recycling waste silk:physical,chemical,and biological methods.Physical recycling is a reuse technology that uses cutting and crushing methods to classify,recycle,and reprocess waste materials,in order to achieve effective recycling of resources.Chemical recycling method refers to the use of special environments or chemical reagents for recycling.It mainly uses a ternary solvent system,lithium bromide solution,formate solution,ionic liquid or other solvents to degumm,dissolve and extract useful substances from waste silk,such as silk fibroin or sericin protein.The biological recycling method mainly converts most waste textiles,including waste silk,into bioenergy through direct combustion or composting.The recycling method is simple and convenient,and can to some extent reduce the burden of landfill.However,burning waste silk will release a large amount of carbon dioxide into the atmosphere.Therefore,combustio
