由于服装的生命周期不断缩短，织物浪费已成为一个日益严重的问题。以前的棉花回收过程使用机械方法将棉花分解成纤维;这是以牺牲强度为代价的。氢氧化钠长期以来一直用于纺织工业，通过丝光处理增加染料吸收和光泽。本文尝试用氢氧化钠的化学作用结合热和机械搅拌力对纯棉平纹细布进行退织。在实验室规模上测试了不同NaOH浓度以确定织物分解的最佳条件。总体而言，用0.5 M NaOH处理的平纹细布织物在纤维质量保持和化学品使用方面取得了最有希望的结果。NaOH溶液是可行的，可以有效地连续退织多个平纹细布织物。虽然退织过程降低了织物的机械强度，但总体而言，回收方法成功地减少了化学废物和退织时间。
Fabric waste has become an escalating problem that stems from the ever-shortening clothing lifecycle. Previous cotton recycling processes used mechanical methods to break the cotton down into fiber; this comes at the cost of compromised strength. Sodium hydroxide has long been used in the textile industry to increase dye absorption and luster through mercerization. In this paper, the deweaving of cotton muslin fabric was attempted using the chemical interactions of NaOH in combination with heat and mechanical forces through agitation. Different NaOH concentrations were tested to determine the optimum condition for fabric decomposition on a laboratory scale. Overall, the muslin fabric treatment with 0.5 M NaOH yielded the most promising results for fiber quality retention and chemical usage. The NaOH solution was shown to be feasible in effectively deweaving multiple muslin fabrics consecutively. While the deweaving process reduces the mechanical strength of the fabric, overall, the recycling method was successful in minimizing chemical waste and deweaving time.
