The deep-dyeing properties,color fastness and dyeing rate curves of acid dyes and neutral dyes are ana-lyzed.The results showed that the optimal dosage of conventional acid dyes,including red C-2RBL,yellow C-3RL and blue C-RL is less than 0.5%.The optimal dosage of shrinkage-resistant acid dyes,including red S-B,yellow S-L and blue S-R is less than 1.5%.The optimal dosage of Isolan neutral dyes,including red NHF-S,yellow NHF-S and blue NHF-S is less than 2.0%.The optimal dosage of Neutrilan neutral dyes,red M-B is below 3.0%,and yellow S-2G and na-vy M-BRX are less than 4.0%.To ensure the level-dyeing properties,the temperature of conventional acid dyes should be slowly increased before 60℃,the temperature of shrinkage-resistant acid dyes should be slowly increased before 70℃,the temperature of Isolan neutral dyes should be slowly increased before 70℃,and the Neutrilan neutral dyes should be slowly increased before 80℃.
