Abstract

The invention discloses an environmental-friendly cotton fabric dyeing. The cotton fabric dyeing comprises the following steps: (1) pretreatment: putting grey cloth into lukewarm water to conduct pre-moistening; adding a pretreatment agent; adjusting pH value to conduct scouring and bleaching; conducting hot washing and cool washing; drying; dyeing; conducting fixation; putting the grey cloth after the pretreatment in the step (1) into water of which the bath ratio is 1:(20-30) in ordinary temperature; adding natural dyestuff, a dispersant, a mordant and a dyeing auxiliary to dye for 20 min; elevating temperature for dyeing for 20-40 min; reducing temperature and adding a fixing agent to conduct fixation; (2) after-treatment: putting the cotton fabric after dyeing into water of which the bath ratio is 1:8 at ordinary temperature; adding soap berry saponin to soak for 10-20 min; washing the cotton fabric; drying. The dyeing is simple and short in production technology, greatly shortens pretreatment time, reduces manufacturing cost, is high in fastness, easy to wash and low in water consumption, and reduces pollution to environment.

Description

Technical field [0001] The invention relates to the field of dyeing and finishing processes, in particular to an environment-friendly cotton fabric dyeing process. Background technique [0002] Due to the pressure of the natural ecological environment, we need to realize cleaner production and energy saving and emission reduction in modern industrial production. How to use the lowest possible cost and reduce pollution while getting good quality is a problem we urgently need to solve. When fabrics are pre-treated and dyed, it is inevitable that there will be cost and pollution problems. The traditional process is to desizing, scouring, bleaching and dyeing cotton fabric step by step, which is stable and good in repeatability. However, the disadvantages of this process are that it takes a long time, the operation process is more complicated, the staff labor is large, the water consumption is large, the energy consumption is large, and the sewage treatment burden is very serious. ...
