Abstract
The invention provides a dye liquor preparation method capable of improving the first-time success rate of cold pad-batch dyeing, which belongs to a dye liquor preparation method for use in printing and dyeing production. The method comprises: a, preparing mixed alkaline solution and dye solution respectively, wherein the mixed alkaline solution is prepared by adding water into a material mixing tank, then adding aqueous solution of sodium silicate and sodium hydroxide are added into the water, stirring the mixture uniformly and the dye solution is prepared by adding water in the dye solution mixing tank, then adding penetrant and urea into the water, adding a reactive dye and stirring the mixture uniformly; and b, delivering the mixed alkaline solution and the dye solution to a chassis by using a proportioning pump to mix the mixed alkaline solution and the dye solution to obtain the dye liquor, wherein in mixing, the volume ratio of the dye solution to the mixed alkaline solution is 4:1. The dye liquor preparation method solves the dye hydrolysis problem of pre-mixing by preparing and mixing the mixed alkaline solution and the dye solution separately, improves the success rate of first-time samples and dye utilization rate and saves production cost.
Description
Technical field
The present invention relates to a kind of compound method of the dye liquor in producing of printing and dyeing, especially a kind of compound method of cold-rolling heap staining dye liquor.
Background technology
The REACTIVE DYES cold-rolling heap staining is a kind of semi-continuous production mode, and it can satisfy the dyeing requirement of all kinds of cellulose base fiber fabrics, and applicable to the dyeing of the cellulose fibre component of BLENDED FABRIC.Its advantage is that equipment investment is few, and mobility strong both be fit to have been produced in enormous quantities, is fit to small lot, many variety production again, and especially comparatively economical during small lot batch manufacture, the auxiliary agent cost is low, and the water consumption energy consumption is low, and blowdown is few.And there is not the migration phenomenon of dyestuff in dye fixing rate height, and the left, center, right aberration is controlled easily, and the front and back aberration is little, and the dyeing product quality is good, and color and luster is plentiful, and feel is good.But the weak point of this cold rolling batch-dying process is, during the preparation dye liquor, being pre-mixed of dye solution and mixed alkali liquor can make REACTIVE DYES issue unboiled water at alkali condition and separate, influence the raising of a sample success rate and the control of front and back aberration, and can cause the alkaline agent waste, increase production cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dye liquor preparation method that improves the cold-rolling heap staining one-time success rate, to improve the one-time success rate of dyeing.
The present invention is achieved in that a kind of dye liquor preparation method that improves the cold-rolling heap staining one-time success rate, and described method is,
A, prepare mixed alkali liquor and dye solution respectively, during the preparation mixed alkali liquor, in joining of water hopper, in water, add sodium silicate aqueous solution and NaOH then and stir mixed alkali liquor, in the mixed alkali liquor, sodium metasilicate content is 120-130g/L, sodium hydrate content is 75-85g/L, and all the other are water; During the preparation dye solution, earlier water is joined in the dye liquor hopper, in water, add bleeding agent and urea then, add REACTIVE DYES again and stir dye solution, bleeding agent content is 0.7-0.9g/L in the dye solution, urea content is 6-12g/L, and REACTIVE DYES content is 0.2-50g/L, and all the other are water;
B, with above-mentioned mixed alkali liquor and dye solution with proportioning pump be sent to mix in the mangle groove dye liquor; During mixing, the volume ratio of dye solution and mixed alkali liquor is 4: 1.
This dye liquor preparation method, mixed alkali liquor and dye solution are separately prepared, are changed material separately, have solved the problem of dyestuff hydrolysis when being pre-mixed, and have improved the sample success rate one time, thereby have improved dye utilization rate, have saved production cost.
The specific embodiment
Further specify the present invention below.
The dye liquor that employing the present invention's method is mixed with is at the additional at any time dye liquor of passing ratio pump in the dye liquor process that pads of dyeing.Dye solution and mixed alkali liquor be separate configuration in change hopper separately, and the passing ratio pump joins in the mangle groove after mixing then, the dye liquor of driving to pad then.Along with the increase of processing quantity, the mixed liquor in the mangle groove can reduce, and in time the passing ratio pump replenishes in the ratio of dye solution and mixed alkali liquor, in case produce aberration.
Described bleeding agent is a kind of among penetrant t A-1, penetrating agent JFC, penetrating agent BX, the bleeding agent JS.
The concentration of described sodium silicate aqueous solution is the 40-42 Baume degrees.
When the dye liquor that this compound method is mixed with is used for cold rolling batch-dying process, earlier cellulose base fiber fabric is carried out pre-treatment, promptly, successively through destarch, mercerising, typing program, finish pre-treatment then the fabric processing of singing.Identical in this pre-treatment and the existing long vehicle knot dyeing technology.Pad dye liquor, clot again, the fixation of banking up.Wash after the fixation of banking up, soap, wash, oven dry, tentering, arrangement, finish dyeing.Operation after the fixation of banking up also with existing long vehicle knot dyeing technology in identical.
When padding dye liquor, fabric is immersed the liquid that pads dye liquor, mixed alkali liquor formation in the above-mentioned mangle groove; When padding, the fluid temperature in the mangle groove is 20-25 ℃, and the middle oil pressure of padding machine is 1.8kg/m
2, both sides air pressure is 1.2kg/m
2, the speed of a motor vehicle is 40 meters/minute, pick-up 65%-68%.
Fabric clot after will padding during clot, is adopted initiatively clot mode, and synchronous with the speed of a motor vehicle of padding machine, the clot time is 40 minutes.
With the fixation of banking up of the fabric after the clot, rotating speed is 8-10 rev/min, and the temperature of banking up is higher than 2 ℃ of fluid temperatures in the mangle groove, environment temperature 20-40 ℃, banks up 12-14 hour.
