中国废旧军服面料回收利用的研究现状及发展前景
Research progress and development prospects of the fabric recycling of waste military uniforms in China
摘要
Abstract
With the continuous development of society and the rapid growth of global textile production,the annual textile consumption per capita and the output of waste textiles have also increased significantly.While the recycling of waste fabrics in China is still at a low-level stage,with a comprehensive utilization rate of less than 15%,resulting in a serious waste of resources and environmental pollution.Due to the variety types of waste civilian clothing and the complexity of corresponding fabrics,it is relatively difficult and costly to recycle them.Waste military uniforms(WMUs)have uniform styles,clear fabric components,and a large amount of usage,and thus become an ideal recycled raw material.If appropriate separation strategies can be adopted to separate various components and further fabricate recycled products based on the fabric components,the high-value recycling and reuse of WMUs will be achieved effectively,which can provide valuable references for the high-value recycling and reuse of wasted civilian clothing. In order to promote the high-value fabric recycling of WMUs in China,we summarized the types and fabrics features of type 07 military uniforms,systematically introduced the present recycle strategies of WMUs,such as splitting spinning,recycled polyester pellets,as well as the separation of polyester/cotton,and prospects the progress of the recycling of WMUs.Current fabric recycling of WMUs mainly focuses on the simple reusage,as well as the recycling of polyester components to prepare recycled polyester pellets.While there are few studies on the high-value recycling of other components,especially on the cotton fibers with high proportion in military uniforms.If effective polyester/cotton separation technologies can be adopted to effectively separate the polyester and cotton fibers,then corresponding recycled polyester pellets and dissolved cotton pulp can be prepared by using the separated components.Regenerated cellulose products can be further fabricated based on the recycled cotton pulp by using this promising strategy.Therefore,the development of high-efficient separation of polyester and cotton,and corresponding high-value utilization of the recycled polyester and cotton components are important development trends of the comprehensive high-value recycling of WMUs.关键词
