WLS助剂改性的棉纱线硫化染料浸染染色工艺研究

摘要

Cotton fabric was modified with cationic agent WLS, the influence of dyeing properties using dip dyeing process with sulfur dye was studied. And the optimal dyeing process of agent WLS modified cotton fabric with sulfur dye was optimized. Then the dyeing properties of the dip dyeing modified cotton fabric with sulfur dye were estimated. The result indicated that the dip dyeing modified cotton fabric with sulfur dye exhibited higher K/S value and higher dyeing percentage. Comparing to traditional crafts, dyeing WLS agent modified cotton solve problems of using sodium bisulfite, low dyeing percentage, wastewater pollution and so on. So the dip dyeing modified cotton fabric with sulfur dye is helpful to energy conservation and development of environmentally friendly dyeing process.%固定阳离子改性剂WLS改性棉纱线工艺，研究硫化染料浸染染色工艺条件对染色性能的影响，优选出改性棉纱线硫化染料浸染染色的最佳工艺，评价了改性棉纱线硫化染料浸染染色效果。结果表明：改性棉纱线硫化染料的上染百分率和K/S值显著提高。WLS助剂改性棉纱线解决了传统硫化染料染色时，还原剂用量大，染料上染率低，染色废水污染严重等问题，这种改性工艺对于节能减排，开发环保型染色工艺非常有利。
