Wasted synthetic fabrics are a type of textile waste source; the reuse of them brings environmental protection and turns waste into a valuable material. In this work, the used nylon (polyamide) stockings were transmuted into a fine fibrous membrane via an electrospinning process. In addition, the safety antibacterial agent, monoacylglycerol (MAG), was incorporated into a recycled fibrous membrane. The results revealed that the neat, recycled polyamide (rPA) fibers with a hydrophobic surface could be converted into hydrophilic fibers by blending various amounts of MAG with rPA solution prior to electrospinning. The filtration efficiency and air/water vapor permeability of the two types of produced membranes, neat rPA, and rPA/MAG, were tested. Their filtration efficiency (E) was more than 92% and 96%, respectively. The membranes were classified according to Standard EN1822, and therefore, the membranes rPA and rPA/MAG were assigned to the classes E10 and E11, respectively. The air permeability was not affected by the addition of MAG, and water vapor permeability was slightly enhanced. Based on the obtained data, prepared rPA/MAG fibrous membranes can be evaluated as antifouling against both tested bacterial strains and antimicrobial against .
废弃的合成纤维织物是一种纺织废弃物来源;对其进行再利用可带来环境保护,并将废物转化为有价值的材料。在这项工作中,用过的尼龙(聚酰胺)长袜通过静电纺丝工艺转化为精细的纤维膜。此外,将安全抗菌剂单酰甘油(MAG)掺入回收的纤维膜中。结果表明,在静电纺丝之前,通过将不同量的MAG与rPA溶液混合,可以将具有疏水表面的纯回收聚酰胺(rPA)纤维转化为亲水性纤维。测试了两种制备的膜,即纯rPA膜和rPA/MAG膜的过滤效率和空气/水蒸气渗透性。它们的过滤效率(E)分别超过92%和96%。这些膜根据标准EN1822进行分类,因此,rPA膜和rPA/MAG膜分别被归类为E10和E11级。MAG的添加不影响空气渗透性,水蒸气渗透性略有提高。根据获得的数据,制备的rPA/MAG纤维膜可被评估为对两种测试细菌菌株具有防污性能,且具有抗菌性能。
