摘　　要：分别讨论PTT纤维碱处理工艺条件对减量率的影响,通过正交试验设计得出PTT纤维碱处理的最佳工艺条件。同时探讨碱处理对PTT纤维结构性能及其表面形态的影响。结果表明:PTT纤维经碱处理后,表面形成明显的坑穴,强度降低,吸湿性能、染色性能提高,当减量率达到15.97%时,其上染率明显提高;在促进剂(1631)浓度为0.003 mol/L条件下,PTT纤维碱处理的最佳工艺条件为NaOH浓度0.875 mol/L,处理时间60 min,温度90℃,PTT纤维的减量率可达到15.97%。The article studied the effect of alkali treatment conditions on the weight reduction,structure and morphology of PTT fibers,and the optimal process conditions were determined by orthogonal design analysis.The results showed that many pits are distributed on the surface of the fibers.The mechanical property has decreased a little,but the wettability and dyeability have improved.When the weight less is 15.97%,their dyeability obviously increases.When the concentration of promoter（1631） is 0.003 mol/L,the optimal process conditions for alkaline treatment of PTT fibers are as follows： the concentration of sodium hydroxide solution,0.875 mol/L;treating at 90℃for 60 minutes.
