摘要: 商品化分散染料中含有較多的分散剂及表面活性剂,但传统水浴染色仍需加入大量的分散剂以提升涤纶纺织品的染色性能,分散剂在纺织工业具有广阔的应用市场。在硅基溶剂染色体系中,当加入商品化分散染料染色时,其会对涤纶染色效果产生不同的影响。文章选取市场上常用的三种分散剂,通过将不同含量的分散剂加入到硅基溶剂染色体系中,研究其在硅基溶剂染色体系中对分散染料染涤纶的影响。结果表明:在硅基溶剂染色体系中,分散染料的上染率与其在溶剂中的溶解度呈反比关系;染色的匀染性和SEM图像表明分散剂并没有沾污在织物上。通过化学计算得到化合物的疏水常数CLogP值,结果发现分散剂和其他助剂的CLogP值越小,即亲水性越好,分散染料的上染率越高。因此,具有高亲水性的助剂可以改善分散染料在硅基溶剂染色体系中的上染率。

Abstract: A large amount of dispersant is added into traditional water-bathed dyeing system to improve the dyeing performance of polyester textile, though commercial disperse already contains many dispersants and surfactants. Dispersants have a broad application market in the textile industry. When commercial disperse dyes are added for dyeing in silicone solvent dyeing system, they would have different effects on the polyester dyeing. In this paper, three different dispersants commonly used in the market were selected to study their influences on the disperse dyes dyeing on polyester in the silicone solvent dyeing system with different amounts of dispersants. The results have shown that the dye absorbing rate of disperse dyes is inversely proportional to their solubility in the solvent in the silicon-based solvent dyeing system. The evenness of dyeing and SEM images showed that the dispersant did not stain the fabric. The value of CLogP, which was the hydrophobic constant, of chemicals can be calculated by the chemical software. The smaller the ClogP value of added dispersants and other chemicals, the better the hydrophilicity of dispersant, the higher the dye absorbing rate of disperse dye. Therefore, accelerants can improve the dye absorbing rate by their high hydrophilicity in the silicone-based solvent dyeing system.

商品化分散染料被广泛应用于涤纶纺织品的传统水浴染色[1]。商品化分散染料配方中已含有一定量的分散剂和表面活性剂,但由于分散染料在水浴中的分散性差,在染色过程中仍需使用大量的分散剂[2]。……
