Description

It is applicable to the Reactive Printing Process of cotton fiber, viscose fiber fabric

Technical field

The present invention relates to a kind of printing technology, particularly relate to a kind of be applicable to cotton fiber, viscose fiber fabric Reactive Printing Process.

Background technology

Reactive dye chromatograph is complete, and wet fastness is good, and PRINTED FABRIC is soft, is cotton fiber, viscose rayon The primary dye of textile printing.And during cotton fiber, viscose fiber fabric stamp, owing to stamp is stuck with paste Class viscosity and the requirement of properties, printing gum water consumption is low, causes dyestuff to be difficult to be completely dissolved.Therefore, In mill base, need to add a large amount of carbamide, help dyestuff to dissolve and swelling of fiber, in order to can pin when decatize Moisture, provides favourable condition for dyestuff and the set of fiber.At present for improve reactive dye dye-uptake and Degree of fixation, and increase gorgeous color and luster, can pad carbamide before stamp, but the ammonia that carbamide decomposites in waste water Nitrogen compound can cause Water Eutrophication, accelerates the growth of algae, influence ecological environment.Along with the world is each How state's raising day by day to environmental requirement, reduce the amount of urea in printing with reactive dye and become printing and dyeing row The big problem of the one of industry, causes the extensive concern of Chinese scholars.

Summary of the invention

It is desirable to provide a kind of Reactive Printing Process being applicable to cotton fiber, viscose fiber fabric, Without carbamide, reduce the content of ammonia nitrogen in waste water, decrease the impact on environment.

In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals:

It is applicable to the Reactive Printing Process of cotton fiber, viscose fiber fabric, it is characterised in that: described tune Slurry comprises the following steps:

1) water of 50% is taken after determining oleo stock total amount；

2) adding sodium hexameta phosphate gently to stir, consumption is 1%-2%；

3) adding reserve salt gently to stir, consumption is 2%-3%；

4) adding sodium alginate stirring, consumption is 5%；

5) adding sodium bicarbonate, consumption is 4%-6%；

6) adding carbamide succedaneum, consumption is 1%-1.5%；

7) benefit is filled with water to 100%, and oleo stock is made in stirring；

8) determining required mill base total amount by fabric load and printed color, the oleo stock taking 50% adds reactive dye；

9) moisturizing is to 90% stirring；

10) adding thickening agent, consumption is 5%-10%；

11) benefit is filled with water to 100%.

Step 5) described in sodium bicarbonate need first carry out material process with cold-water solution.

Step 6) described in carbamide succedaneum be Hangzhou celebrating friend weaving Chemical Co., Ltd. research and development carbamide succedaneum NR。

Due to the fact that the above technical scheme of employing, substitute carbamide, fabric tinctorial yield liter with carbamide succedaneum NR Also reduce the content of ammonia nitrogen in waste water while height, decrease the impact on environment.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is described in further detail:

Embodiment 1:

Stamp 3000m cloth, color is conventional black, and required usage of sizing agent is 300kg, and concrete quantization is as follows: Take 75kg water, add 2.4kg sodium hexameta phosphate, stir 5 minutes, add 3.6kg reserve salt, stir 10 Minute, it is slowly added to 7.5kg sodium alginate, and adds suitable quantity of water, stir 40 minutes, good little of additionization Soda, i.e. takes 7.5kg sodium bicarbonate and is dissolved in 5kg cold water, adds 1.8kg Hangzhou celebrating friendly weaving Chemical Co., Ltd. The carbamide succedaneum NR of research and development, mending and being filled with water to total amount is 150kg, stirs, makes oleo stock；Additionization Good reactive dye (take 27kg and be dissolved in 10kg warm water), add thickening agent 15kg, and benefit is filled with water to total amount and is 300kg, carries out stamp after stirring.

Above-mentioned slurry compares to cotton fabric stamp with using carbamide slurry, and tinctorial yield is high by about 5%.

Above-mentioned slurry compares to viscose fiber fabric stamp with using carbamide slurry, and tinctorial yield high 5% is left Right.

After above-mentioned slurry carries out stamp, in waste water ammonia nitrogen value be 6.1mg/L, BOD value be 17.8；Use urine Element slurry carry out stamp, in waste water ammonia nitrogen value be 47.5mg/L, BOD value be 58.0.

In a word, the foregoing is only presently preferred embodiments of the present invention, all made according to scope of the present invention patent Impartial change with modify, all should belong to the covering scope of patent of the present invention.
