摘　　要：采用臭氧对靛蓝染色后的尼龙56纤维进行脱色处理,探讨了各工艺条件对脱色效果和力学性能的影响,优化了臭氧脱色的工艺条件。结果表明:当臭氧处理时间为20 min、pH=9左右、纤维含湿量为20%时,尼龙56纤维力学性能保持良好且脱色效果最佳。The indigo dyed nylon 56 fiber is decolorized by ozone.The effects of the process conditions on the decolorization effect and mechanical properties are discussed,and the ozone decolorization process is opti⁃mized.The results show that when the ozone treatment time is 20 min,the pH is about 9,and the moisture content of the fiber is 20%,the mechanical property of the PA56 fiber remains well and the decolorization ef⁃fect is the best.
