For reaching above-mentioned purpose, the present invention is achieved in that
A kind of dyeing process of cotton fiber, comprise concise to cotton fiber, dyeing, step such as post processing and oven dry, REACTIVE DYES is adopted in described dyeing, according to different color requirements, the ratio of various dyestuffs, dyestuff and glauber salt were dropped into the dye vat material 20~30 minutes together, turned round at normal temperatures then 10~30 minutes, be warming up to the required temperature of dyestuff with 0.5~3 ℃/minute speed, select the suitable alkali rate curve that adds according to different dye characteristic, utilization adds alkali equipment automatically and begins to add liquid caustic soda, add that alkali is intact held temperature 15~30 minutes, get rid of raffinate then, carry out post processing.The described alkali equipment that adds automatically is the automatic monitored control system of adding dyestuff and auxiliary agent in the dope dyeing operation automatically, form by automatic adjusting control valve and system of automatic function software, its principle is the requirement according to the adding speed of dyestuff and auxiliary agent, auto-control software can be regulated the flow of automatic valve, reaches the different alkali speed that add.Because the present invention adopts and adds alkali equipment automatically, rely on machine to control whole dyeing course, so not only reduced interference and the working strength of workers of human factor, and guaranteed the good dyeing repeatability of dye-works dyeing.
Described post-processing step be included in 45 ℃~60 ℃ down in and 10~15 minutes, adding 0.25~0.8 grams per liter concentration is 98% glacial acetic acid, then under 80 ℃~95 ℃, soaped 10~20 minutes, the soaping agent that adds 2 grams per liters, washed 5~10 minutes 45 ℃~60 ℃ heat, look shade and do 1~2 time, under 45 ℃~60 ℃, carried out the fixation soft treatment 10~20 minutes at last, the softener of last 2~5 grams per liters behind the color-fixing agent of adding 2~3 grams per liters.
Described refining process is: cotton fiber is put into bath raio in normal temperature be 1: 10~15 water, adds 2~3 grams per liter chelated dispersants, directly is warmed up to 90 ℃~100 ℃ and held temperature 30~60 minutes, begins dyeing after cooling to the temperature that dyeing needs again.
The invention has the beneficial effects as follows: because this technology uses is liquid caustic soda dyeing, has obviously reduced cost, effectively shortens dyeing time, enhances productivity, and has also reduced the expense of water power simultaneously, can relax the situation of the society of present water resource and electric power resource anxiety.And because liquid caustic soda is a highly basic, pH value height when the pH value ratio of liquid caustic soda dyeing when dyeing is used soda ash, characteristic according to REACTIVE DYES, pH value height in the dye liquor is high adsorption capacity then, so will dye an identical color, the new technology of chart two will be saved about dyestuff 5%-10% than the technology of chart one, in like manner, because the absorbability of dyestuff has improved, dyeing finishes that residual dyestuff reduces relatively in the sewage effluent of back, thus also minimizing relatively of the cost of disposing of sewage.
