摘　　要：为改善再生涤纶织物的吸湿速干性能,分别采用质量浓度为20、25和30 g/L的Na OH溶液和0.5 g/L的阳离子表面活性剂1227溶液,通过碱减量工艺对再生涤纶织物进行处理。对织物经碱减量处理后的减量率以及表征织物经碱减量处理前后吸湿速干性的各指标进行测试。结果表明:使用质量浓度为20 g/L的Na OH溶液进行碱减量工艺处理时织物减量率在15%以下,织物物理性能变化小;经碱减量工艺处理后的织物滴水扩散时间明显降低;吸水率与织物经纬向芯吸高度大幅度增加;织物蒸发速率和单位时间内透湿量均明显增加;经碱减量工艺处理后的再生涤纶织物吸湿速干性能得到明显提高,且满足吸湿速干性产品的技术要求,对开发导水型再生涤纶织物有一定的指导意义。In order to improve the moisture absorption and quick-drying properties of recycled polyester fabrics,20,25 and 30 g/L Na OH solution and a small amount of cationic surfactant 1227 were used to treat recycled polyester fabrics by alkali reduction process. The reduction rate and all indicators for the characterization of moisture absorption and quick-drying properties of treated and untreated fabrics were tested. The testing results of all indicators were analyzed. The results showed that reduction rate is low when using 20 g/L Na OH solution in the alkali reduction process. The physical properties of fabrics have little changed. For treated fabrics,the dripping diffusion time significantly reduced,and water absorption and wicking height of fabrics have substantial increased. The evaporation rate and water vapor permeability in unit time increased obviously. The recycled polyester fabric＇ s moisture absorption and quick-drying properties improve significantly by the alkali reduction process,and the treated fabrics meet technical requirements of the moisture wicking products.
