Fig. 2 is ultra-low bath ratio dyeing installation (high merit GF241-XL ultra-low bath ratio dyeing machine).
The specific embodiment
Below in conjunction with embodiment, to details are as follows according to the specific embodiment provided by the invention:
Ultra-low bath ratio beam dyeing method of the present invention has embodied the characteristics of short process low energy consumption, effectively the advantage of utilization dyeing solves the refining of deoiling in the yarn dyeing process, satisfies the whiteness requirement, satisfies powerful requirement, satisfy the capillary effect requirement, satisfy dyeing cloth cover quality requirement.
One, operating procedure: a kind of ultra-low bath ratio beam dyeing method, comprise pre-treatment, dyeing and post processing, bath raio is 1: 4-6, its pre-treatment may further comprise the steps:
(1) add auxiliary agent, described auxiliary agent comprises refining enzyme, degasifier and dispersant;
(2) add again auxiliary agent 27.5-50% hydrogen peroxide;
(3) speed with 0-3.2 ℃/min is warming up to 110 ℃, moves 20-30 minute, decides on steam pressure, and pressure is lower than 5.5bar and then controls without speed;
(4) arteries and veins flowing water washes into, adds dispersant QH-210;
(5) be warming up to 90 ℃, move 5 minutes, then draining cooling adds except oxygenase, adds acetic acid again, then is warmed up to 60-70 ℃, insulation operation 5 minutes.
In the above-mentioned steps, improved charging rate, traditional feed pattern is to adopt slowly to add, and generally will circulate at least just added hydrogen peroxide in 2-3 minute.And, do not need to add hydrogen peroxide stabilizer, reduced cost of material, reduced pollution.
Improved the technique water-washing method, traditional handicraft generally is to adopt overflow washing or direct draining to carry out cold water to clean 3-5 minute, adopt arteries and veins flowing water wash can in the situation that the control water yield realize powerfully cleaning and yarn not being exerted an influence, time, short water consumption was low, as long as the water consumption of traditional 30%-40%.
Improve the process heat coolant-temperature gage, the tradition washing generally is to adopt cold water to clean, and the dilution that however, residual base and the oxygen amount of fiber can not be complete is cleaned.It is to be based upon to heat on a small quantity under the higher prerequisite of cylinder body temperature own to carry out the thermal cycle cleaning that hot water cleans, and effectively solves the residual alkaline agent of high temperature refining and remaining oxygen, and the condition that fully satisfies follow-up cleaning improves dyeing quality.
Preferably, the addition of described auxiliary agent is refining enzyme 6.5-7g/l, degasifier 1.5g/l, dispersant 0.6g/l, 50% hydrogen peroxide 6-8g/l, QH-2100.6-0.8g/l, removes oxygenase 0.6g/l, acetic acid 1.3g/l.(satisfy and be adjusted to the requirement of dyeing pH value)
Further, preferred, step (5) is moved 5 minutes for being warming up to 90 ℃, and then draining cooling adds except oxygenase, adds acetic acid again, then is warmed up to 65 ℃, insulation operation 5 minutes.
Preferably, described refining enzyme is refining enzyme 1128.
Further, the auxiliary agent that uses in the staining procedure comprises dispersant GD, and the consumption of dispersant GD is 1.0-2.0g/l.
Further, salt adding is 2-3 time in the staining procedure, and each 3-5 minute, add alkali 2 times, each 3 minutes, once (quantifying feed) 15-20 minute adopted unidirectional Rapid Circulation.
The fixation temperature retention time is 25,30,40,50 minutes, lacks 10-30 minute than traditional.
It is pure unidirectional changing traditional endless form, reduces the difficulty that manufactures and designs, and realizes Rapid Circulation dyeing exchange.Improve pickling temperature, the high temperature pickling is an emphasis process that effectively solves fiber pH value and cleaning, traditional handicraft generally is exactly to be based upon low temperature and cold wash pattern, and such yarn top layer and the PH effect of internal layer are inconsistent, also can show the anti-yellow phenomenon of whiteness.
The feed time that improves in the dyeing course shortens with frequency, by former salt adding 2-3 time, foreshortens to 3-5 minute in 10-15 minute at every turn, adds alkali and shortens to for 3 times 2 times, and 1 time 3 minutes, one time dosing fed in raw material 15-20 minute.
The present invention has improved the performance mode of traditional infiltration refining auxiliary agent, adopts high dispersive alkali resistance auxiliary agent.Shortening the process time raises the efficiency; Shorten frequency and time 50% that dyeing adds accelerant; Shorten and add alkali (color-fixing agent) working time 40%-60%; Shorten dyeing time 25%.
