摘要
利用实验室自制的聚羧酸盐类分散剂制备液体分散染料,研究了分散剂用量和种类对分散染料粒径的影响。结果表明:分散剂质量分数为15%(对染料质量),染料含固量为10%时,制备的液体分散染料粒径为194.5 nm,多分散指数(PDI)为0.220,离心稳定性为95.7%,放置30 d后平均粒径在250 nm以下。将制备的液体分散染料分散橙30、分散蓝291∶1和分散紫93∶1按照质量比3.7∶1.3∶1.0拼混后染涤纶,可染得颜色均匀的藏青色,且各项色牢度皆优。
The liquid disperse dyes are prepared with the self-made polycarboxylate dispersant.The effects of the amount and type of dispersant on the particle size of disperse dyes are studied.The results show that when the dispersant is 15%(to dye mass)and the solid content of dye is 10%,the particle size of liquid dis⁃perse dye is 194.5 nm,the polydispersity index(PDI)is 0.220,the centrifugal stability is 95.7%,and the average particle size is below 250 nm after 30 days.Disperse Orange 30,Disperse Blue 291∶1 and Disperse Violet 93∶1 liquid disperse dyes are mixed according to the mass ratio of 3.7∶1.3∶1.0 to dye polyester,a uniform navy blue color can be obtained,and all color fastnesses are excellent.
