Technological process of controlled cheese dyeing with reactive dyes is introduced,including dye selection,ratio of dyestuff to alkali and salt,control of dyeing conditions,factors affecting levelness,as well as characteristics and applicability of high-temperature-high-pressure cheese dyeing machine.

This paper analyzes the sampling management of dyed yarn in color weaving and common factors leading to color deviation ranging from the trials to bulk production, as well as among the different batches in cheese dyeing and finishing.

The cruxes in real silk package dyeing lie in medium lift, large flow, application of inner commutative centrifugal pump, precision winding and packing, and degumming under high temperature and pressure.
