Abstract:

The wool was treated by low temperature plasma and was dyed with high concentrations of 5% o.w.f Lanasol CE series reactive dyes, then a kind of clean energy-saving deep dyeing process of wool was developed .The effects on dyeing properties of wool pretreated with different conditions were investigated systematically and a better condition was optimized. The results proved that the dyeing properties of plasma-treated wool dyed with Lanasol CE series reactive dyes (black) dyeing at 80℃ were remarkably better than the traditional dyeing condition (98℃), which showed dyeing rate and fixation respectively increased by 21.63% and 6.25% , as well as the wash fastness climbed by 0.5 grades.

Key words: low temperature plasma, wool, Lanasol CE series reactive dye, dyeing
