Technical field
The present invention relates to technical field, more particularly to a kind of ethanol is with dyeing technique.
Background technology
Dyeing under traditional aqueous systems, between 0.1%-7%, water has two effects to dye material consumption, and one is dissolving dye
Material, two is that, used as carrier offer dye bath environment, the effect of transport dye material, salt plays the effects such as rush dye and fixation.
Traditional dyeing uses a large amount of water and a large amount of inorganic salts：Often contaminate 1 ton of fiber, more than 8 tons of water, add pre-treatment and after
Treatment often contaminates one ton of fiber between water 60-100 tons.National annual 1200000000 tons of water of dyeing, environmental pressure is huge, due to waste water
Middle inorganic salts are very difficult to remove, and cause the destruction of water and soil pollution and ecological environment, therefore how to subtract with water and few salt in source
Using becoming an extremely challenging problem.
Although also there is the method to textile dyeing using organic solvent dye liquor miscible with water in the prior art,
In actual industrial application, can all occur dye-uptake substantially reduce, dyeing time it is long, water consumption is big, the problem of power consumption height etc.,
Be not suitable for large-scale promotion application.
The content of the invention
The present invention provides a kind of ethanol aiming at above-mentioned defect with dyeing technique.The present invention uses ethanol system
Under salt-free dyeing technology, significantly reduce and use water salt dosage, economic benefit social benefit is notable.Dyeing water and traditional handicraft phase
Than reducing 90%-95%, ethanol is recycled, basic to realize dyeing zero-emission；Dyeing time shortens 50%, dyeing temperature reduction
10-20 DEG C, energy-conservation more than 30% solves the problems, such as textile sewage with the scheme of zero-emission.
A kind of ethanol of the invention is to use the water for accounting for pollutant 5%-8% percentage by weights with dyeing technique technical scheme
Dissolving dye material, adds the ethanol solution for accounting for pollutant 92%-95% percentage by weights, does not use inorganic salts, dyeing course
In, using gradient increased temperature, pressurization dyeing, ethanol volumetric concentration is more than 90% in described ethanol solution.
Described pollutant is cylinder yarn, cloth or staple in bulk.
A kind of described ethanol is comprised the following steps with dyeing technique：
(1) for alkali：In material pond, water is added, water is defined can flood pollutant, 40-50 DEG C of water temperature, add soda ash
Stirring makes pH value reach 8-9 addition pollutants after 5 minutes；70 DEG C are warmed up to, insulation is taken out after 30 minutes；
(2) liquid carrying rate control：Liquid carrying rate treatment will be carried out using liquid carrying rate processing equipment for alkali pollutant, make its liquid carrying rate
Reach 70%-100%；Liquid carrying rate=(weight-dry weight after dehydration)/dry weight.
(3) dye liquor is prepared：During reactive dye are dissolved in into the warm water of pollutant weight 5%-8%, water temperature is controlled in 30-35
DEG C, stirring forms aqueous dye solutions；Stirred in the ethanol solution that aqueous dye solutions are poured into pollutant weight 92%-95%
Mix, form ethanol water dye liquor；
(4) dye, pollutant is inserted in dye liquor, it is closed to be warming up to 40 DEG C and kept for 10-15 minutes, then it is warming up to 60-
70 DEG C, 3Mpa is forced into, is kept for 10-15 minutes；
(5) cool down：Using water cooling, dye vat is carried out to be cooled to 25-30 DEG C of degree, dye liquor is collected to dye liquor storage tower；
(6) squeeze：Dye liquor in pollutant is squeezed out, the dye liquor that will be squeezed out is collected to dye liquor storage tower.
Described pollutant is cylinder yarn, cloth or staple in bulk.
In step (1), soda ash consumption is 20-50g/L dye liquors.
In step (1), 70 DEG C are warmed up to 1 DEG C per minute of speed.
In step (2), described liquid carrying rate processing equipment, including staving, reel rotating shaft, reel and motor, also wrap
Bung is included, the bung is pivotally connected with staving, and Pneumatic power support lever is provided between bung and staving；Separated by a dividing plate in the staving
