The key of the process is the use of the plasma technique as a pretreatment of the PP fabrics before vatdyeing.
该工艺的关键是在还原染料染色前利用等离子技术对PP纤维进行预处理。

Aiming at the problems of colour fluctuation in cheese VATdyeing, methods of controlling colour shade are investigated from the reduction of dyes, process of dyeing, oxidizing, soaping and drying.
On the Basis of an experiment on the dyeing technology of solubilized vat dyes on chinlon, the light-degradation of the fibre is emphatically discussed.
