Abstract Upcycle of waste fabrics has been a promising project since it can reduce textile pollution and provide a prospect to waste management. In this work, a multiple recyclable transparent functional film was fabricated through ionic liquid (IL) assisted regeneration process with a higher yield of 90.40%, compared with other polymer regeneration process using IL. Fourier Transfer Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), UV-visible Spectrophotometer, as well as tensile strength test were carried out to explore the performance of the regenerated jute film. This transparent renewable jute film can be made into many functional materials, like packaging materials, electrically conductive films or information storage devices. Furthermore, it can be dissolved in IL and regenerate new films for multiple cycles, which can still maintain a relatively high transparency and a considerable mechanical property. Compared to other fabric recycle process, the solvent and production both can be effectively recycled, which can be considered as a green and sustainable tool to manage waste fabrics.

具有功能特性的废黄麻织物升级回收制备的高柔性透明薄膜

摘要 废旧织物的回收利用可以减少纺织品污染，为废物管理提供前景，是一个很有前景的项目。在这项工作中，与其他使用 IL 的聚合物再生工艺相比，通过离子液体 (IL) 辅助再生工艺制备了多重可回收透明功能膜，产率高达 90.40%。进行傅里叶转移红外光谱（FTIR）、X射线衍射（XRD）、紫外-可见分光光度计以及拉伸强度测试，以探索再生黄麻薄膜的性能。这种透明的可再生黄麻薄膜可以制成许多功能材料，如包装材料、导电薄膜或信息存储设备。此外，它可以溶解在 IL 中并在多个循环中再生新的薄膜，仍能保持较高的透明度和相当的机械性能。与其他织物回收工艺相比，溶剂和生产都可以有效回收，可被视为一种绿色和可持续的废弃织物管理工具。
