摘　　要：使用NaOH、KOH、快速润湿剂和减量剂对100%聚酯织物进行处理,探讨了碱处理对织物物理性能的影响。采用4种不同的100%聚酯试样,用碳酸钠精练后进行热定型,然后测试织物的经、纬纱线密度、芯吸性和撕裂强度等物理性能。再次用碳酸钠精练织物并进行热定型。最后用不同质量浓度的NaOH和快速润湿剂、NaOH和减量剂、KOH和快速润湿剂、KOH和减量剂,以及KOH和快速润湿剂与减量剂的组合对织物试样进行碱减量处理。研究表明:碱处理后聚酯织物经纱密度和纬纱密度减小,织物面密度减小,经、纬纱线密度降低,芯吸时间缩短,抗撕裂强度下降,润湿性提升。The Effect of alkali treatment on physical properties of 100%polyester fabric has been studied using NaOH,KOH,rapid wetting agent and weight reducing agent.For this purpose,4 different 100%polyester samples were taken and scoured with sodium carbonate and then heat set.This was followed by testing for physical properties like warp and weft denier,wickability and tearing strength.The fabric was then scoured with sodium carbonate and heat set again.Both the samples were then given weight reduction treatment with different amounts of NaOH and rapid wetting agent,NaOH and weight reducing agent,KOH and rapid wetting agent,KOH and weight reducing agent,and KOH and combination of both.A reduction not only in the number of ends per inch,picks per inch,fabric weight,warp and weft yarn count occurred,but also a reduction in wicking time and tearing strength occurred,while percentage wettability increases.
