对苯基苯酚在涤纶染色中的应用研究

Application of P-phenylphenol in Polyester Dyeing by Disperse Dyes

将对苯基苯酚用于涤纶织物分散染料载体染色中,测试并分析了对苯基苯酚用量、染色温度、保温时间对染色效果的影响,并采用正交试验法进行染色工艺优化。探讨了三原色染色效果以及染色后织物的耐水洗色牢度和断裂强力。结果表明,涤纶分散染料对苯基苯酚载体染色时,织物上染率提高;分散蓝E-R加载体染色最佳工艺为:对苯基苯酚用量30%,染色温度95℃,保温时间45 min;分散蓝E-R、分散黄E-3GB染色时得色量较大,分散红E-FB染色时得色量较小;对苯基苯酚载体染色后织物的耐水洗色牢度不受影响,断裂强力有所下降。

P-phenylphenol was applied in polyester carrier dyeing by disperse dyes. The effects of amount of p- phenylphenol, temperature and time on the dyeing effeet were tested and analyzed, and optimal dyeing process was obtained through orthogonal experiment. Dyeing properties with three primary color dyes, color fastness to wash and breaking strength of fabric after dyeing were discussed. The results show that the dye uptake improves in polyester dyeing by disperse dyes with p-phenylphenol as carrier; the optimal disperse blue E-R carrier dyeing process is that the dosage of p-phenylphenol is 30%, dyeing temperature is 95℃, time is 45 minutes; color yield of fabric dyed by disperse blue E-R and disperse yellow E-3GB are bigger, but that of disperse red E-FB is smaller. Color fast- ness to washing of fabric dyed by p-phenyl phenol earrier dyeing is not affected; and its breaking strength declines.
