摘要/Abstract

摘要： 通过对分散染料、涂层胶和涂层溶剂溶度参数的计算以及各自行为的分析，运用溶度参数理论对涤纶涂层织物在生产和存储过程中发生色变的机理进行了研究。结果表明：涂层织物生产和储存过程中分散染料的迁移情况与涂层胶和涂层溶剂的溶度参数有关：生产过程中，与染料溶度参数接近的涂层胶会增加染料从纤维内部向表面的迁移，但可以缓解储存过程中分散染料在织物表面的不均匀迁移色变；在存储过程中，残留溶剂的挥发是染料发生不均匀迁移的主要原因，当溶剂与染料溶度参数相近、沸点过高或过低时，不均匀迁移更易发生。为缓解涂层织物的色变现象，应在涂层加工过程中选择与染料溶度参数值相近的涂层胶及与染料溶度参数值相差较大的涂层溶剂。

Abstract: Through the solubility parameter calculation of disperse dyes, coating agents and organic solvents as well as the analysis of their behavior, the mechanism of color change of the coated polyester fabrics in manufacturing and storage was studied in terms of solubility parameter theory. The results show that the dye migration both in fabric coating manufacturing and storage was related to the solubility parameter of coating agents and organic solvents. In manufacture process, the coating agent with similar solubility parameter to disperse dyes’ would cause dye migration from inner fiber to fabric surface, but relieve the color change caused by uneven migration of disperse dyes during storage. The main reason for uneven dye migration during storage was the volatilization of entrapped solvent, and the uneven dye migration was more easily to occur when the solubility parameter of solvent and disperse dyes were close, or the boiling point of solvent was too high or too low. In order to reduce color change phenomenon of the coated polyester fabrics, close solubility parameter between coating agent and disperse dyes as well as far solubility parameter between organic solvent and disperse dyes were chosen.

Key words: solubility parameter, coating, disperse dye, migration, color change
