Abstract

The invention discloses a one-bath agent for a reactive dye and a disperse dye used in dyeing. The one-bath agent comprises the following components in percentage by mass: 50%-60% of pectinase, 35%-45% of cellulase, 3%-8% of surface active agent, 2%-3% of reactive dye protective agent, 1%-2% of alkaline fixing agent and 1%-2% of preservative. The one-bath agent for the reactive dye and the disperse dye used in dyeing has the advantages that the disperse dye and the reactive dye can be fully fused, fusing time is shortened, steps and time consumption of dyeing are reduced, the yield is increased, the production cost is reduced, and an environmental-friendly disperse and reactive dye one-bath agent and dyeing technique are obtained.

Description

The same bath agent of DISPERSE DYES and REACTIVE DYES for dyeing

Technical field

Type of the present invention relates to textile printing field, relates in particular to a kind of dispersed activity dyeing with bathing agent and dyeing method.

Background technology

Known textile industry is the conventional column industry of China, and in factory, generally adopt Dyeing with Disperse/Reactive dyeing for textile dyeing at present, owing to disperseing, the dyeing condition with REACTIVE DYES is far from it, DISPERSE DYES generally dyes under high mild acidic conditions, and REACTIVE DYES need to dye under low temperature and alkali condition, the two dye can not well and fast merge, thereby fabric is dyeed, and under prior art especially for the T/R in fabric, the general technique adopting of sun sticky cloth kind fabric is two-bath process, and by traditional Dyeing with Disperse/Reactive one-bath two-step process dyeing, disperse and the process that merges of REACTIVE DYES in, need the technique of cost long, sewage disposal load is heavy, fibre damage is large, the difficulty of checking colors, and difficult quality control, thereby output and production cost are greatly affected.In technical process, another kind of colouring method passes through Dyeing with Disperse/Reactive two one-bath two-step process dyeings, and its technique 4.5-5h that is about consuming time is more loaded down with trivial details than Dyeing with Disperse/Reactive one-bath two-step process dyeing, has greatly improved production cost.In order to make up in prior art for DISPERSE DYES and REACTIVE DYES being reached to good fusion, reduce dyeing sewage quantity long and that produce large, the problem such as reduce production costs costly, the invention provides a kind of dispersed activity dyeing with bathing agent and dyeing method.

Summary of the invention

The present invention has overcome the defect of Shortcomings in prior art, and provide one fully DISPERSE DYES and REACTIVE DYES to be merged, reduction time of fusion, reduces dyeing and technique is consuming time, improve output, reduce production costs and the dispersed activity of environmental protection dyes with bath agent and dyeing method.

To achieve these goals, the technical solution used in the present invention is:

The same bath agent of DISPERSE DYES and REACTIVE DYES for dyeing, described dyeing with constituent and the proportioning of bathing agent is: pectase 50-60%, cellulase 35-45%, surfactant 3-8%, REACTIVE DYES protective agent 2-3%, set alkaline agent 1-2%, preservative agent 1-2%.

Use this with bathing agent dyeing, its concrete technology step comprises:

A, first fabric and suitable quantity of water are joined in dye vat;

B, the water in dye vat is warmed to 30 DEG C, then adds glauber salt, dyeing with bathing agent and REACTIVE DYES (keeping a period of time);

C, on the basis of step b, heat up 30-40 minute to 60 DEG C time, then be incubated 30-40 minute and carry out reactive dyeing;

D, on the basis of c step, heating up 20 minutes to 80 DEG C time adds glacial acetic acid to neutralize again;

E, on the basis of d step, be incubated 15 minutes, add DISPERSE DYES;

F, on the basis of e step, heat up 30-40 minute to 135 DEG C, be incubated and within 30-40 minute, carry out disperse dyeing;

G, on the basis of f step, after dyeing, fabric is carried out sample, water outlet and soaped while being cooled to 80 DEG C, dyeing completes.And need strengthen soaping for dark kind, wherein soaping agent consumption is 1.0-2.0g/L, and temperature is 90-95 DEG C, and the time is 15-20 minute.

Described dispersed activity is with bathing the constituent and the content that add in agent dye process:

Beneficial effect of the present invention: this technology adopts dyeing to include other functional aid such as REACTIVE DYES protective agent, set alkaline agent with bathing in agent, can first put into REACTIVE DYES then add between DISPERSE DYES (acid adding after first alkali) by the one-bath two-step process dyeing heating up, REACTIVE DYES and DISPERSE DYES can be coordinated fully, shorten the time of its cooperation, made it possible to better, carried out fast dyeing; This technique has shortened dyeing flow process greatly; make dyeing time than shortening now 30% left and right; also greatly improved output; reduced the consumption of energy and the water yield, the water yield has been saved 30% left and right, has also reduced the consumption of alkali; thereby reduce production costs; in sewage, the content of alkali reduces simultaneously, is conducive to environmental protection, has the economic benefit of energy-saving and emission-reduction.

Detailed description of the invention

Fabric is dyeed by following technological process: the first step, first joins fabric (T/R or positive sticky cloth class) and suitable quantity of water in dye vat, second step, is warmed to 30 DEG C, then adds glauber salt, dyeing is with bathing agent and REACTIVE DYES (keeping a period of time), and wherein dyeing has REACTIVE DYES protective agent with bathing agent main component, set alkaline agent, surfactant, preservative agent, pectase, cellulase element, wherein with bathing, in agent, it consists of by weight percentage: 50-60% in dyeing, cellulase 35-45%, surfactant 3-8%, REACTIVE DYES protective agent 2-3%, set alkaline agent 1-2%, preservative agent 1-2%, then heats up 30-40 minute to 60 DEG C, is incubated and within 30-40 minute, carries out reactive dyeing, heating up 20 minutes to 80 DEG C time adds glacial acetic acid to neutralize again, be incubated 15 minutes, add DISPERSE DYES, because the alkali resistance of the conventional DISPERSE DYES of major part is poor, DISPERSE DYES need to add (and adding acetic acid neutralization) after vital staining finishes, and next heats up 30-40 minute to 135 DEG C, is incubated and within 30-40 minute, carries out disperse dyeing, while being finally cooled to 80 DEG C after dyeing, carries out sample dying thing, water outlet and soaping, dyeing completes.Wherein after dyeing, needing reinforcement washing and the object of soaping is except deactivation, the loose colour of DISPERSE DYES on fabric, improves color fastness and the gorgeous degree of fabric.

The constituent of adding in dye process and content are: water is for appropriate, described activity, DISPERSE DYES (owf) content is X%, glauber salt addition is 20-50g/L, dyeing is 2-3g/L with bathing agent addition, (dyeing is 2.5g/L left and right with the reference consumption of bathing agent, actual amount is as the criterion to draw a design), glacial acetic acid addition is 2.5-3.5g/L, glacial acetic acid addition is 2.5-3.5g/L, dye bath ratio (contaminating the ratio of mode fabric and dye liquor) is 8-10, and need strengthen soaping for dark kind, wherein special-purpose soap lotion is 1.0-2.0g/L, temperature is 90-95 DEG C, time is 15-20 minute, described in the same bath of dispersed activity agent dye process, when light-colored dyeing, glauber salt consumption is unsuitable too high.

Beneficial effect of the present invention: this technology adopts dyeing to include other functional aid such as REACTIVE DYES protective agent, set alkaline agent with bathing in agent, can first put into REACTIVE DYES then add between DISPERSE DYES (acid adding after first alkali) by the one-bath two-step process dyeing heating up, REACTIVE DYES and DISPERSE DYES can be coordinated fully, shorten the time of its cooperation, made it possible to better, carried out fast dyeing; This technique has shortened dyeing flow process greatly; make dyeing time than shortening now 30% left and right; also greatly improved output; reduce the consumption of energy and the water yield, made the water yield save 30% left and right, also reduced the consumption of alkali; thereby reduce production costs; in sewage, the content of alkali reduces simultaneously, is conducive to environmental protection, has the economic benefit of energy-saving and emission-reduction.
