Abstract

The present invention relates to a silk dying auxiliary agent and a silk dying process. In the silk dying process, silk is firstly put in a dye vat, water is added to the dye vat, the silk is heated, a mixed auxiliary agent formed by mixing 90% to 120% of oxydol, 10% to 30% of sodium silicate, 1% to 3% of chelating dispersion agent and 1% to 3% of scouring agent is added to the silk which is then heated to 90 DEG C to 100 DEG C, the water is discharged after the heat is insulated for at least 30 min, and then water and 0.5% of vivid dimensional Vettekaes auxiliary agent are added so that the second pretreatment working procedure is carried out; dyes and the water or the mixture of the dyes are directly added to the dye vat after the dye vat is cleaned by clear water, and silk is dyed under a heating condition. The water added to the dye vat in the dyeing technology of the present invention is soft water; the present invention the characteristic of obviously improving the lustre, the whiteness and the brightness of the silk so that the silk has smooth and soft hand feeling and elasticity, the quality of the silk is enhanced by at least one grade, and especially the consumption of short-fiber silk can be reduced by 1 to 2%; according to the estimation of economic benefits, the quality of the silk can be enhanced by 2000 to 3000 yuan/ton, and the consumption is reduced by 1% to 2%; according to the calculation of finished product silk of 15 to 20 yuan/ton, nnamely 2000 to 3000 yuan/ton, the sum is about 5000 yuan/ton.

Description

A kind ofly dye an auxiliary agent and dye a technology

Technical field

What the present invention relates to is the auxiliary agent of a kind of manufactured silk dyeing and dyes a technology, belongs to a kind of printing technology field of textiles.

Background technology

In the prior art, known textile dyeing technology has many kinds, it mainly selects corresponding dyeing for use according to different textiles kinds, dyeing as present manufactured silk mainly comprises pretreatment procedure and after stain wire process, specifically include: yarn is put into dye vat, the back start that discharges water is heated to 60 ℃ of shutdown, adds the auxiliary agent that hydrogen peroxide and sodium silicate are formed then; Start is heated and be incubated 50 minutes after 98 ℃ again, cleans with clear water after the draining, descends the road to dye wire process then.It is the yarn after the clear water cleaning to be added water add dyestuff or add mixed dye in dye vat that this road, back dyes wire process, what have can also add dyeing assistant, after the insulation regular hour under the condition of heating, cleans with clear water, carry out fixation and softness then, go out cylinder after drying promptly finish.Though the dyeing of above-mentioned yarn has been mature technique comparatively, but because added hydrogen peroxide auxiliary agent is a kind of strong oxidizer in its pretreatment procedure, its purpose is the impurity of removing in the yarn, but it damages also for simultaneously the fibroin of yam surface, husky line feel after the therefore final wherethrough reason is hardened, loss height, whiteness brightness are difficult to improve, and weave and the product quality of husky line causes tangible influence follow-up.In addition, in dyeing course, traditional process using all be hard water since hard water in calcium, magnesium ion be adsorbed on yam surface, cause the yam surface dimness.

Summary of the invention

The object of the present invention is to provide a kind of improved technology, it can obviously improve manufactured silk textiles whiteness, brightness, gloss, feel etc. after dyeing, and can reduce the wastage dye an auxiliary agent and dye a technology.A described auxiliary agent that dyes, it mainly is a kind of auxiliary agent of the pretreatment procedure that dyes, it includes hydrogen peroxide and sodium silicate blending ingredients at least, wherein also adding at least has chelated dispersants, refining agent to constitute mixed aid, the mixed proportion of above-mentioned each component is a weight standard with 100 parts of dyed yarns, is mixed with 90-120 part hydrogen peroxide respectively, 10-30 part sodium silicate, 1-3 part chelated dispersants, 1-3 part refining agent.Each component optimum mixture ratio example of described mixed aid is that weight standard is with 100 parts of dyed yarns: 100 parts of hydrogen peroxide, 20 parts of sodium silicates, 2 parts of chelated dispersants, 2 parts of refining agents.

A kind of adding has a technology of dying of above-mentioned auxiliary agent, it comprises that earlier yarn being put into dye vat adds the water adding assistant, under the condition of heating, carry out pretreatment procedure, in dye vat, directly add dyestuff and water or dye mixture after cleaning with clear water then again, and under the condition of heating, carry out yarn dyeing; The present invention adds the water heating and adds the mixed aid that is mixed by hydrogen peroxide, sodium silicate, chelated dispersants, refining agent after yarn is put into dye vat, be warming up to 90---100 ℃ of insulation draining after at least 30 minutes then.

Dyeing of the present invention, it is in dying a pretreatment procedure, add water and add that mixed aid is handled and draining after, also at least again Jia Shui, add gorgeous Wei Taikesi auxiliary agent and carry out the second road pretreatment procedure.

It is described that to dye the water that is added in the dye vat in the pretreatment procedure all be soft water.

The water that is added in dye vat in the dyeing of the present invention all is soft water.

The present invention compared with prior art, have obvious gloss, whiteness, the brightness of improving spun silk, make the feel of spun silk sliding soft, flexible, grade improves one-level at least, staple fibre class spun silk especially, and characteristics such as loss 1-2% can descend, by the economic benefit estimation, the yarn grade can improve 2000---3000 unit/ton; Loss decline 1-2% is 2000---3000 unit/ton by ten thousand yuan of/ton finished product yarns calculating of 15-20, is aggregated in about 5000 yuan/ton.
