Description

Washing methods after textile cone yarn active macromolecules dyeing

Technical field

The present invention relates to the rear method for washing and processing of reactive dyeing, relate in particular to the method for washing and processing of a kind of textile cone yarn after dark reactive dyeing.

Background technology

Following a large amount of impurity is contained without solution in the washing yam surface of post processing and the duct of fibre gap after reactive dyeing terminates:

1) REACTIVE DYES in dyeing course for improve dyestuff dye-uptake and add a large amount of neutral electrolyte-glauber salt;

2) for making dyestuff and cellulose fibre form stable covalent bonds and adding a large amount of color-fixing agent-soda ash;

3) non-set and occurred be hydrolyzed dyestuff;

4) for a change colored state and some other chemical assistants added;

5) yarn produces and some remaining other impurity in process.

Because above-mentioned impurity exists, must wash fully after dyeing terminates, to remove these impurity, ensure stable, qualified COLOR FASTNESS, good feel and the aft-loaded airfoil performance of the yarn color after dyeing.

In whole REACTIVE DYES yarn dyeing process, especially in cone yarn active macromolecules dyeing process, the rear washing process after dyeing is loaded down with trivial details especially and complicated, consume a large amount of water, the energy and time.In traditional post processing washing process, before soaping, necessarily carry out 3-4 road hot water wash and go floating process, soap temperature requirement at about 98 DEG C, also need high temperature to wash after soaping, the water that post processing washing process uses, the energy and time account for more than 60% of above-mentioned key element consumption in whole dyeing course.Therefore optimizing washing process after dyeing, is reduce water and energy resource consumption, saves production time most effective method.

Summary of the invention

Technical problem to be solved by this invention is the washing methods after providing a kind of textile cone yarn active macromolecules dyeing, through the colour stable of the textile cone dyeing yarn of the method process, every fastness index meets or exceeds national standard requirement, the method possesses economize energy, reduce and consume, improve the effect of production capacity.

For solving the problems of the technologies described above, washing methods after textile cone yarn reactive dyeing of the present invention, comprises the following steps:

(1) desalt operation

In dye vat, add desalter DYE2.0g/L in textile cone yarn dyeing course, drain dye liquor in dye vat after dyeing terminates, be then full of soft water again, carry out the normal temperature liquid flow water wash of 15 minutes;

Add desalter DYE2.0g/L to refer to the volume of dye vat as benchmark adds desalter DYE according to 2.0g/L ratio.

(2) soap washing

Fill soft water in dye vat, add engineering and to soap enzyme 5NPF2.0g/L, be warming up to 80 DEG C, isothermal holding gets rid of raffinate to the greatest extent after 15 minutes; Continue to add soft water, add floating agent RG-MC1.0g/L, be warming up to 80 DEG C, isothermal holding got rid of raffinate after 10 minutes;

Add the engineering enzyme 5NPF2.0g/L that soaps to refer to and to soap enzyme 5NPF for benchmark adds engineering according to the ratio of 2.0g/L with the volume of dye vat.Add floating agent RG-MC1.0g/L to refer to the volume of dye vat as benchmark adds floating agent RG-MC according to the ratio of 1.0g/L.

(3) in and operation

Fill running water in dye vat, add organic acid ACR1.0g/L, 50 DEG C of neutralization &washing discharge opeings after 15 minutes; Continue to add running water, be warming up to 80 DEG C, isothermal holding got rid of raffinate after 10 minutes;

Add organic acid ACR1.0g/L to refer to the volume of dye vat as benchmark adds organic acid ACR according to the ratio of 1.0g/L.

(4) fixation softening step

In dye vat, note soft water, adds organic acid ACR0.5g/L, adds color-fixing agent TWE3.0%owf, after 50 DEG C of insulation 15 clocks, adds liquid wax AWG4.0g/L, continues insulation discharge opeing after 15 minutes;

Add organic acid ACR0.5g/L to refer to the volume of dye vat as benchmark adds organic acid ACR according to the ratio of 0.5g/L, add color-fixing agent TWE3.0%owf and refer to that color-fixing agent accounts for 3% of yarn qualities, add liquid wax AWG4.0g/L and refer to the volume of dye vat as benchmark adds liquid wax AWG according to 4.0g/L.

(5) water squeezing baking operation

Treated textile cone yarn is gone out cylinder and carries out water squeezing oven dry, the yarn moisture control after water squeezing is 60 ~ 70%, and bake out temperature controls at 90 DEG C-105 DEG C, and after drying, finished yarn regain controls between 8.0%-9.0%.

Described step (1) all completes to (4) in the dye vat of cone dyeing machine.

Between described step (2) and step (3), also comprise step (2.1): in dye vat, again fill soft water, add floating agent RG-MC1.0g/L be warming up to 80 DEG C insulation 15 points after blowdown.Contaminating in rear carrying out washing treatment process to carrying out activity with large molecular dye, because the loose colour after Large molecule active dyeing is serious, this step can go to float further, improves clean result.

Between described step (3) and step (4), also comprise step (3.1): fill running water in dye vat, 80 DEG C of Water Unders wash discharge opeing after 10 minutes.Carrying out in the process of active dye with dark fuel textile cone yarn, this step can improve clean result.

Above-mentioned desalter DYE is produced, the name of an article: desalter, the trade mark: desalter DYE by three adopted fine chemistry industry (Suzhou) Co., Ltds (also claiming 3E fine chemistry industry (Suzhou) Co., Ltd); Above-mentioned color-fixing agent TWE is produced by three adopted fine chemistry industry (Suzhou) Co., Ltds, the name of an article: color-fixing agent, the trade mark: color-fixing agent TWE; The above-mentioned enzyme 5NPF that soaps is produced by east, Hefei Mei Jie macromolecular material Co., Ltd, the name of an article: enzyme of soaping, the trade mark: soap enzyme 5NPF; Above-mentionedly go floating agent RG-MC by Desang Shanghai Fine Chemical Co, the name of an article: go floating agent, the trade mark: remove floating agent RG-MC; Above-mentioned organic acid ACR is produced by Italian Bu Saite company, the name of an article: organic acid, the trade mark: organic acid ACR; More than be commercial industrial product.

In technique scheme, desalter DYE directly adds in dyeing liquor, at the end of dyeing DYE can by be present in solution in fibre gap duct with salt be adsorbed in fiber surface, thus very easily remove by the washing of rear road, traditional technique necessarily carries out 3-4 road hot water wash before soaping, as long as and after adopting desalter one normal temperature liquid flow water wash just can reach effect same; Secondly apply the low temperature soaping technology of enzyme of soaping, traditional temperature 98 DEG C of soaping can be down to less than 80 DEG C, and wash without the need to high temperature after soaping; Apply organic acid again fiber is neutralized completely; Finally utilizing the fixing property of color-fixing agent TWE, promote the hydrolised dye that exists in liquid and fiber stable bond, being firmly combined reacting to be formed with the dyestuff that fixation occurred fiber; Process non-polymer in last process to stay in working solution.

Washing post-processing approach of the present invention, under the prerequisite that, flow process low in temperature is short, the key technical indexes such as finished product coloured light repeatability and dyefastness are all better than or are equivalent to and traditional handicraft.Except temperature of soaping needs 80 DEG C, other operation is all carried out at not higher than 50 DEG C, reduces the energy and water consumption more than 30%, saves time more than 1/3rd.Reach economize energy, reduce and consume, improve the object of production capacity.
