Abstract

The invention relates to soaping compound enzyme and an application method thereof. The soaping compound enzyme comprises laccase, persulfate and PVP (polyvinylpyrrolidone), and sodium citrate is also added in the soaping compound enzyme. The soaping compound enzyme comprises the following compositions in percentage by mass: 55-80 of the laccase, 15-30 % of the persulfate, 4-10 % of the PVP, and 1-5 % of the sodium citrate. In the soaping compound enzyme disclosed in the invention, cooperative anxoaction can be generated between the sodium citrate and the laccase as well as between the persulfate and the PVP, and thus the whole soaping effect of the soaping compound enzyme is greatly increased. Compared with the traditional soaping technology, according to the soaping compound enzyme disclosed by the invention, the absorbance of raffinate after soaping is obviously reduced, the clarity is increased, and thus the treating difficulty of sewage is reduced; the fastness to wet rubbing of a cloth sample after soaping in increased by 0.5-1 level, and the soaping fastness is increased by 0.5 level; and three washing procedures are saved, 30% of the water consumption is saved, 30% of the procedure time is saved, the production cost is greatly reduced, and the environment pollution is reduced.

Description

A kind of soaping with prozyme and application method thereof

Technical field

The invention belongs to technical field of textile printing, be specifically related to a kind of soaping with prozyme and application method thereof.

Background technology

In the textile printing and dyeing field, the application of reactive dyestuffs is more and more extensive at present.The dyeing of reactive dyestuffs is ripe, and chromatogram is complete, particularly development in recent years the double-active radical dye of a series of high colour-fast rates, Color is greatly improved.But because reactive dyestuffs can be hydrolyzed when dying set, hydrolised dye is adsorbed on the colour fastness that can have a strong impact on dyeing product on the fiber, thereby must carry out water after the reactive dyeing and soap, purpose is to remove the hydrolised dye attach on fiber, not set dyestuff and other impurity.

Cotton is printing and dyeing mill's dyeing after treatment aids commonly used with soaping agent, and Main Function is that flush away is not combined and the reactive dyestuffs of set with fiber.Traditional soaping agent such as acrylate type, mainly be by with the hydrolised dye complexing action, remove the loose colour of fabric face, stop dyestuff in the washing lotion to return again and be stained with cloth cover, improve the washing fastness of fabric, but not obvious to the fastness to wet rubbing effect of deep colour dyeing fabric.In order to improve the colour fastness of reactive dyestuffs deep color dyeing fabric, 2 high temperature commonly used are soaped and are reheated the powerful cleaning of water or select preferably vat dyes dyeing of fastness, but this method production process is long, the water power steam consumption increases, the waste water absorbancy is dark, quantity discharged is large, and the sewage disposal load is large, and production cost is high.

In addition, after the dyeing, re-use laking agent and carry out fixation, by forming the color lake, crosslinked and film forming make crock fastness can access to a certain degree improvement, but colour fixation is good often, and fastness to wet rubbing promotes high, and the change of dyeing coloured light is also large.

Summary of the invention

The purpose of this invention is to provide a kind of soaping with prozyme and application method thereof, be a kind of can by in the Javelle water with fiber surface not the dissolving dye of set reach the purpose of colour killing, the laccase mixture to having had no effect with the dyestuff of fabric by covalent bonds simultaneously, thus remedy the deficiencies in the prior art.

Of the present invention soaping used prozyme, includes laccase, persulphate and polyvinylpyrrolidone, also is added with Trisodium Citrate.

Above-mentioned each component and the mass ratio thereof of soaping with prozyme is respectively: laccase 55%-80%, persulphate 15%-30%, polyvinylpyrrolidone 4%-10% and Trisodium Citrate 1%-5%.

Above-mentioned persulphate is one or several in Potassium Persulphate, Sodium Persulfate, the ammonium persulphate.

Prozyme of the present invention is used for cleaning the cloth after dyeing, and comprises following step:

1) the cloth cold water flush 10min after at first will dyeing;

2) use again the glacial acetic acid solution of 1g/L to wash cloth 10min;

3) add above-mentioned soaping by 0.2～1g/L and use prozyme, bath raio 1:10,10min is processed in 80 ℃ of insulations, repeats to wash 2 times;

4) cold wash 10min finishes cleaning.

Of the present invention soaping produces collaborative promoter action with Trisodium Citrate in the prozyme and laccase, persulphate and polyvinylpyrrolidone, thereby greatly improved the effect of soaping of prozyme integral body.Compare with the tradition technique of soaping, the soap absorbancy of rear raffinate of the present invention obviously reduces, and clarity improves, thereby has reduced the intractability of sewage; The fastness to wet rubbing of rear cloth specimen soaped has improved the 0.5-1 level, and soaping fastness has improved 0.5 grade; Save 3 road washing steps, save 30% water consumption, shorten 30% activity time, can greatly reduce production costs environmental contamination reduction.

From the table data can find out, compare with traditional soaping agent, use prozyme of the present invention to soap after, the absorbancy of raffinate obviously reduces, the clarity of raffinate is improved, thereby greatly reduces the intractability of sewage.The soap fastness to wet rubbing of rear cloth specimen of prozyme has improved the 0.5-1 level, and soaping fastness has improved 0.5 grade.Than the tradition technique of soaping, the technique of soaping of the present invention has been saved 3 road washing steps, has saved 30% water consumption, has shortened 30% activity time, can greatly reduce production costs environmental contamination reduction.

Embodiment 5

Trisodium Citrate is to the collaborative promoter action of laccase, persulphate and polyvinylpyrrolidone

1, complex enzyme formula design:

Control group: laccase 70g, ammonium persulphate 20g, polyvinylpyrrolidone 7g.

Experimental group 1: laccase 70g, ammonium persulphate 20g, polyvinylpyrrolidone 7g, Trisodium Citrate 0.49g(account for total mass 0.5%)

Experimental group 2: laccase 70g, ammonium persulphate 20g, polyvinylpyrrolidone 7g, Trisodium Citrate 0.98g(account for total mass 1%)
