摘要
以 Lanasol 三原色对羊毛散纤维进行染色，通过改变工艺条件，对比染色后织物的各项性能，研究最适合羊毛染色的工艺条件和参数．实验结果表明，使用 Lanasol 染料对羊毛进行染色时的最佳工艺为染液 pH 控制在4～5，染色温度在85～100℃下均可，元明粉用量控制在5％（owf）以下，适量加入1％～2％的 Albegal B ，固色 pH 在7左右．加入0.1g /L 亚硫酸氢钠可以在低温下（80℃）达到较高的上染率和固色率．
By using the Lanasol series reactive dyes ,changing the process conditions ,and comparing the various performance of dyed fabrics ,the most suitable conditions and parameters for wool dyeing process are studied .The optimum process is determined as follows ：The pH of dye solution should be controlled in 4 to 5 ,dyeing temperature is between 85 ℃ ~ 100 ℃ ,the amounts of odium sulfate anhydrous should be controlled under 5% ,adding moderate 1% ~ 2% Albegal B ,the pH for fixing can be 7 .In addition ,When adding 0.1g/L sodium hydrogen sulfite ,the wool can be dyed in the low temperature and maintain higher dyeing rate and fixation yield .
