Postindustrial textile has incrementally become a major issue of global concern over the last decade, especially, synthetic textiles, given their non-biodegradability, toxicity and expected growth with ever-increasing production quantities. Absence of proper waste management facilities and technologies poses both environmental and social challenges in textile waste management. Multi-material systems further increase the complexities in textile recycling. Mixing of Spandex with Nylon to improve stretchability of fabrics is extremely common nowadays although it renders Nylon almost impossible to be recycled. Here in, a complete process to develop a novel thermal insulation material is presented, using synthetic material cutting waste (Nylon/Spandex and Polyurethane). Thermal insulation panels were developed using compression moulding. A sample matrix of panels with different proportions of Nylon/Spandex and Polyurethane was subjected to testing for thermal conductivity. The combination giving the best thermal insulation was experimentally found to be 60% Nylon/Spandex fabric shreds mixed with 40% Polyurethane shreds. The thermal insulative behaviour of the novel material was modeled using a power series, using the material thickness as the parameter.
在过去十年中，后工业化纺织品逐渐成为全球关注的主要问题，尤其是合成纺织品，因为它们不可生物降解、有毒，而且预计随着产量的不断增加，其产量还会继续增长。缺乏适当的废物管理设施和技术，给纺织品废物管理带来了环境和社会方面的挑战。多材料系统进一步增加了纺织品回收的复杂性。如今，将氨纶与尼龙混合以提高织物的弹性非常普遍，尽管这使得尼龙几乎不可能回收。在这里，提出了一种使用合成材料切割废料（尼龙/氨纶和聚氨酯）开发新型隔热材料的完整工艺。使用压缩成型来开发隔热板。对具有不同比例的尼龙/氨纶和聚氨酯的板的样品矩阵进行了热导率测试。实验发现，具有最佳隔热效果的组合是 60%的尼龙/氨纶纤维碎片与 40%的聚氨酯碎片混合。使用幂级数对新型材料的热绝缘性能进行建模，使用材料厚度作为参数。
