Production method for dyeing cheese dyeing viscose special yarns and direct dyes

Abstract

The invention relates to a printing and dyeing method, in particular to a production method of cheese dyeing viscose special yarns and direct dyes. The production method comprises the following steps:sample yarn selection, slack winding, caging, pretreatment, auxiliary agent formula compounding, dyeing formula designing, cheese dyeing, treating after washing, sampling and coloring match, softening and fixing, uncaging, dehydration, drying, sampling for a difference in the leveling properties of sampling yarns in inner, middle and outer layers of a cheese, cheese tightening, and packaging. Theproduction method of the cheese dyeing viscose special yarns and direct dyes has obvious effects of energy saving and emission reduction, and the hand feel and elasticity, and fullness of color of produced and processed yarns, and the looming rate of woven fabric are high, and the leveling properties of inner, middle and outer layers of the cheese (the layer difference also meets the requirementof weaving all plain fabrics) and various quality internal indicators can meet the requirements of customers.

Description

technical field [0001] The invention relates to a printing and dyeing method, in particular to a production method for dyeing viscose special yarn and direct dye dyeing of cheese. Background technique [0002] Reactive dyes are generally used in the existing viscose product dyeing process, because the reactive dye dyeing process is complicated, the processing time is long, the production cost is large, the energy consumption is high, and the processing technology uses a large amount of sodium sulfate, which makes sewage treatment very difficult. Big. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art, and solves the problems of long processing time, high energy consumption, high production cost and difficult degradation of dyed sewage in the production and processing of existing viscose products. The auxiliary agent is added to the package dyeing, and through the improvement of the process technology, the problems of l...

[0003] The present invention mainly solves the deficiencies in the prior art, and solves the problems of long processing time, high energy consumption, high production cost and difficult degradation of dyed sewage in the production and processing of existing viscose products. The auxiliary agent is added to the package dyeing, and then through the improvement of process technology, the problems of long processing time, high energy consumption, high production cost and difficult degradation of dyeing sewage in traditional reactive dye package dyeing are solved.
