超声波在大麻织物染色中的应用

Application of ultrasonic technology in the dyeing of hemp fabrics

为了拓宽超声波技术在染色领域中应用范围,以还原染料对大麻织物的染色为例,对超声波染色进行了研究。结果表明,与常规染色工艺相比,在提高染色织物摩擦牢度的同时,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,从而节约能源,提高生产效率,使还原染料对大麻织物的低温、短时间染色工艺成为可能。

In order to open up the application field of ultrasonic technology in textile dyeing, an applied study of ultrasonic dyeing of the hemp fabric with vat dyes was carried out. The results show that compared with the conventional dyeing process, ultrasonic dyeing technology can improve the abrasion fastness of the dyed fabric significantly, enhance dye up-take with the amount of dyes lessened and environment-pollution reduced,increase the diffusion coefficient, thus reducing the activated energy of dyeing, saving energy and raising productivity. Ultrasonic technology makes it possible the low temperature dyeing of the hemp fabric with vat dyes in a shortened process.
