环保型高色牢度锦纶超纤绒面革的染色工艺研究

Dyeing process of environmental friendly high color fastness nylon microfiber suede leather

研究了不同的染色体系对锦纶超纤绒面革的染色效果以及后整理工艺对绒面革的涂饰影响,结果表明:采用分散染料和酸性染料一浴法染色,可以有效地降低绒面革中重金属的含量,提高水洗牢度和耐光照牢度,进而通过后整理表面涂饰,可以降低分散染料的色迁移。一浴法染色相对于两浴法,染色流程简化,成本低,染色成品颜色易控制。

The dyeing of nylon Microfiber suede with different dyeing systems and the effect of finishing process on the finishing leather were studied.The results show that the content of heavy metals in the suede leather is effectively reduced by the use of disperse dyes and acid dyes in one bath,the washing fastness and light fastness can be improved.After finishing the surface finishing,it can reduce the color migration of the disperse dyes.One bath dyeing is relative to the two bath method.The dyeing process is simplified,the cost is low and the color of the finished product is easy to control.
