超声波在羊毛染色中的应用

Application of ultrasound in dyeing wool with acid dye

以酸性大红G为例,对超声波在羊毛染色中的作用进行研究。结果表明,与常规染色工艺相比,在提高染色织物皂洗牢度的同时,超声波染色不但可以提高染料的上染百分率,节约染料,降低环境污染,而且可以增大扩散系数,降低染料上染的活化能,降低染色温度,缩短染色时间,从而节约能源,提高生产效率,使酸性染料对羊毛的低温短时间染色工艺成为可能。

Based on Dyeing wool with acid red G, ultrasound dyeing was investigated. It appeared that on the basis of achieving a high soap-washing fastness, compared with conventional dyeing process, ultrasound dyeing can increase dye up-take, save the amount of dyes, improve environment-pollution, enlarge diffusion coefficient, reduce that active energy of dyeing, low dyeing temperature, shorten dyeing time, therefore save energy, develop productivity. It is possible that wool was dyed with acid dye at low temperature in short time. Obviously, ultrasound dyeing process is rational in economic and feasible in technology, it has a broad development prospective.
