Description

A kind of silk-cotton fabric co-bathing dyeing method

Technical field

The present invention relates to field of printing and dyeing, particularly the co-bathing dyeing method of silk-cotton fabric.

Background technology

Silk-cotton fabric had both had the good moisture permeability of cotton fiber and had also comprised advantages such as polyamide fibre favorable elasticity, high-wearing feature, was widely used in all kinds of clothing fabrics, liked by consumers in general.But owing to polyamide fibre, cotton fiber have various structure, different dyeing performance, dyeing brings chromatography difficulty, the long problem of technological process to enterprise often.On printing technique, dyestuff is an ACID DYES on the best of polyamide fibre, but under acid condition, REACTIVE DYES are not painted basically to cotton fiber, and REACTIVE DYES must be in fixation under the alkali condition, and alkali condition can produce significant impact to the polyamide fibre stamp.Under the alkali condition, the polyamide fibre dye-uptake is very low, and a large amount of dyestuffs are water-washed away, and the dyestuff that is water-washed away not only influences the stamp COLOR FASTNESS to cotton and the mutual staining of polyamide fibre, and stamp is stain in vain, influences product quality.Therefore, the collaborative good cotton stamp condition that both oppose each other with brocade is to produce the problem that high quality of products must solve.

At present, most enterprises adopt neutrality/activity, faintly acid/active two bath methods to dye, and this process has chromatography and is easy to advantage, but also have the shortcoming that REACTIVE DYES are infected with polyamide fibre, technological process is long, energy resource consumption is big, discharge of wastewater is many.Polyamide fibre is a polyamide fiber, and its molecule mainly is made up of three parts: the amide groups bridge of promptly hydrophobic methylene moiety, possess hydrophilic property and the amino and the carboxyl of the end of the chain.REACTIVE DYES dye on can be with polyamide fibre amino effect fixation.Because amino content is less, adopt REACTIVE DYES that polyamide fibre is dyeed, generally believe to have the low characteristics of tinctorial yield.But show through a large amount of tests, REACTIVE DYES are reasonably screened, dye effect on the middle dark color and still can reach.Therefore, adopt REACTIVE DYES that silk-cotton fabric is carried out co-bathing dyeing research and have feasibility, and technological process is short, washing fastness good because it has, application prospect is comparatively wide.

At present, when adopting REACTIVE DYES that silk-cotton fabric is carried out co-bathing dyeing, need to solve the subject matter of following two aspects: be to make REACTIVE DYES close to polyamide fibre, cotton dyeing capacity respectively on the one hand, obtain homochromatism preferably; Make the utilization rate of REACTIVE DYES reach higher level on the other hand, promptly make two component Dry Sacks all reach higher level as far as possible.But owing to polyamide fibre, cotton knot structure difference, REACTIVE DYES are demonstrated the different dyeing performance, various technological factors differ to dying influence degree on polyamide fibre, the cotton, the problem that the homochromatism effect is undesirable, process conditions are regulated and control difficulty occurs through regular meeting.So the regulation and control of process conditions become the key problem in technology of homochromatism dyeing.Documents and materials once reported,, but often attended to one thing and lose sight of another reaching the homochromatism effect through the regulation and control of dye bath pH value, and resultant effect is relatively poor.

Summary of the invention

To the deficiency of prior art, one of the object of the invention is to provide a kind of silk-cotton fabric co-bathing dyeing method, is intended to solve silk-cotton fabric with the problems such as compatibility difference of bathing stamp.

For realizing above-mentioned purpose, the technical scheme that the present invention adopted is: a kind of silk-cotton fabric co-bathing dyeing method, and this decoration method adopts following steps:

(1) silk-cotton fabric is carried out destarch, boiling-off, bleaching process etc. and carry out pre-treatment;

(2) will pass through the fabric pre-setting of pre-treatment, the setting process condition is 170 ℃ of temperature, 40 seconds time;

(3) add water by the silk-cotton fabric weight of required dyeing and 15: 1 bath raio, the running of input fabric drops into after 5 minutes has successively changed REACTIVE DYES M-2GE, acetic acid 2ml/l, sodium hydrogen phosphate 2g/l, the reserve salt 3g/l that the good concentration of material is 1.8% (owf), heats up then and is incubated and move 30 minutes; Add sodium carbonate 25g/l, urea 3g/l, sodium sulphate 20g/l then; Insulation operation 40 minutes, be cooled to 60 ℃ after the draining flushing, adding water to bath raio then is 1: 15; Add soaping agent 3g/l; When being heated to 90 ℃, washed 15 minutes, the cooling draining is washed, is dried; Adopt the neutral dye fixing agent FRC of environmental protection that it is carried out fixation treatment then, carry out afterboarding and tentering at last.

The invention has the beneficial effects as follows: the present invention has successfully solved to print on the silk-cotton fabric dyestuff and has dyed the difficult problem that characteristic is runed counter to, the degree of fixation that has solved silk-cotton fabric is low, dyefastness is poor, staining seriously, efficiently soap, a series of problems such as technological process is long.Through this method, make bright and beautiful cotton fiber lining on dye flow process more rationally, produce clean environment firendly, constant product quality, the staining fastness of silk-cotton fabric is brought up to 6 grades from the 1-2 level, dyes manyly on the cotton and polyamide fibre, homochromatism is good.

The specific embodiment

Embodiment one

(50: 50 mass ratio inputs, the COTTON FABRIC specification is: bleaching cotton poplin, 40 to the cotton biased sample of brocade ^s* 40 ^s, 132 * 72,120g/m ²Polyamide fibre 6 fabric specifications: 70D/24F, grammes per square metre is 130g/m ²) processing of dyeing.Adopt following steps:

(1) silk-cotton fabric is carried out destarch, boiling-off, bleaching process etc. and carry out pre-treatment;

(2) will pass through the fabric pre-setting of pre-treatment, the setting process condition is 170 ℃ of temperature, 40 seconds time;

(3) add water by the silk-cotton fabric weight of required dyeing and 15: 1 bath raio, the running of input fabric drops into after 5 minutes has successively changed REACTIVE DYES M-2GE, acetic acid 2ml/l, sodium hydrogen phosphate 2g/l, the reserve salt 3g/l that the good concentration of material is 1.8% (owf), heats up then and is incubated and move 30 minutes; Add sodium carbonate 25g/l, urea 3g/l, sodium sulphate 20g/l then; Insulation operation 40 minutes, be cooled to 60 ℃ after the draining flushing, adding water to bath raio then is 1: 15; Add soaping agent 3g/l; When being heated to 90 ℃, washed 15 minutes, the cooling draining is washed, is dried; Adopt the neutral dye fixing agent FRC of environmental protection that it is carried out fixation treatment then, carry out afterboarding and tentering at last.

Dyeing back adopts Datacolor SF-600 to survey the color matching appearance, under D65 light source and 10 ° of visual angles, with the CIELab system DYED FABRICS is measured, and obtains the apparent color depth value K/S value and the aberration Δ E of polyamide fibre, COTTON FABRIC respectively.For same fabric and same dyestuff, the K/S value is big more, and its apparent colour is dense more, on dye many more, otherwise then light more, on dye few.The size of aberration Δ E is weighed the homochromatism between fabric polyamide fibre and the cotton component, and aberration is more little, and homochromatism is good more, otherwise then poor more.The cotton K/S value that present embodiment obtains is 16.53, and the K/S value of polyamide fibre is 17.46, and aberration Δ E is 0.93.It is thus clear that it is all better to dye effect on cotton of the present invention and the polyamide fibre, and homochromatism is good, aberration is little.
