| description | The invention discloses a method for treating waste fabrics containing polyester and elastic fibers, which comprises the following steps of: performing at least two stages of separation treatment on the waste fabrics by using at least one polar solvent, and then recycling the treated waste fabrics, the polar solvent is selected from a group consisting of dimethyl formamide (DMF), dimethylacetamide (DMAC), N-methyl pyrrolidone (NMP), gamma-butyrolactone (GBL) and dimethyl sulfoxide (DMSO); and the polar solvent is selected from a group consisting of dimethyl formamide (DMF), dimethylacetamide (DMAC), N-methyl pyrrolidone (NMP), gamma-butyrolactone (GBL) and dimethyl sulfoxide (DMSO). The treatment method disclosed by the invention can be used for efficiently recovering the polyester and the elastic fiber in the waste fabric, has remarkable environmental and economic benefits, and meets the requirements of industrial production.
本发明公开一种包含聚酯和弹性纤维的废旧织物的处理方法，其是使用至少一种极性溶剂对废旧织物进行至少两个阶段的分离处理，然后再回收处理后的废旧织物，极性溶剂是选自于二甲基 |
