Abstract
A dyeing method with disperse dye includes dyeing with general disperse dye and dyeing with the disperse dye in the form of micro softgels. Its advantage is no need of water washing.
Description
Technical field
The present invention relates to the light industry field, specifically a kind of method of exempting the disperse dyeing of washing.
Technical background
Staining technique always comprises the dyeing of DISPERSE DYES to hydrophobic synthetic fibre fabric such as terylene and yarn, and all essential powerful washing is so that reach necessary COLOR FASTNESS index.Usually adopt disperse dyeing, the following PROCESS FOR TREATMENT of process: dyeing, as being incubated 1 hour at 130 ℃; Also to wash after the dyeing, as bath raio 30: 1～100: 1,60～80 ℃, 10 minutes; And then through soaping, as being incubated 10 minutes at 95 ℃; The reduction washing was as 70 ℃ of insulations 10 minutes; Oven dry at last.We can say that removing removal floating color with washing is dyeing personnel's required course, also is reach the COLOR FASTNESS quality important, or even unique means.And wash, comprising the reduction washing and soaping is the important pollution entering the water of dyeing factory.
First of the output Jun Ju world of China's DISPERSE DYES and polyester fiber, its dyeing also occupies huge ratio in China's printing and dyeing industry.So using water wisely is particularly carried out no waste water and is dyeed, in DISPERSE DYES to dying hydrophobic fiber technologies such as terylene with regard to the special significant meaning of tool, also have great environment protection significance.In China, one ton of cloth of dyeing post rinse needs 100 tons to 200 tons of waters, if adopt this washing process of exempting from, can significantly reduce dyeing rinsing water withdrawal, improves water-use efficiency.Particularly, increase substantially and use ratio of water recycle, thoroughly solve the dyeing waste problem microcapsule dyeing technology.
Around this problem, the scientific worker that dyes has for many years done a large amount of research and has explored.Adopt nanometer technology to improve the dyestuff performance as the dyestuff manufacturing, adopt grain forming technique and microcapsules and film-coating technique etc., the dyer author has developed supercritical CO
2Technology such as fluid staining technique, non-aqueous system dyeing, pigment dyeing, but all await further popularization.
Up till now, inventor such as Chen Shuilin had once invented a kind of microcapsule disperse dye does not have waste water dyeing---microcapsule dyeing technology (Chinese patent publication number: 1443894).The microcapsule disperse dye staining procedure: dyeing is incubated 1 hour, soaps and dries as 130 ℃.This technology has effectively solved the dyeing waste-water problem, and the dyeing draining is capable of circulation to be utilized or directly discharging again.But reach good COLOR FASTNESS, in particularly dying, when dark, also must and soap by means of washing.Still fail thoroughly to solve the wastewater problem in the whole dyeing, in other words, the washing after the dyeing and soap to consume promptly the water yield of polluting huger than dyeing itself.
Summary of the invention
The purpose of this invention is to provide a kind of method of exempting washing.This disperse dyeing method comprises general disperse dyeing and microcapsule disperse dye colouring method, exempt wash, soaps, operation such as reduction cleaning, to reach using water wisely, protect the purpose of environment.
The present invention's method can be described as a kind of hungry colouring method, make loose colour enter fiber fully, improve every COLOR FASTNESS thereby present the state of dying, need not again through the reduction washing and soap, washing etc., can save a large amount of back washings, the present invention also has the effect that obviously improves level-dyeing property in addition.
The purpose of dyeing after washing is to remove the loose colour of fiber surface absorption, improves every COLOR FASTNESS.Traditional after washing comprises the reduction washing, soaps etc., all be negatively the dye transfer of not set to water.So the great cost that improves COLOR FASTNESS just becomes a large amount of water and pollutes.It is minimum to the present invention is based on DISPERSE DYES solubility in water, and hydrophobic fibre had the characteristics of affinity, suitable external environment condition is provided, promptly in the water of 100 ℃～130 ℃ of high temperature, be incubated 10～30 minutes, make the dyestuff of fiber surface absorption enter fiber, be converted into the state of dying by loose colour---so-called hungry dyeing that Here it is, can reach the purpose that improves COLOR FASTNESS equally, or else needed after washing.Simultaneously, dye molecule is easy to move and dyes with this understanding, can further improve the level dyeing degree of fabric.
The present invention is particularly suitable for not having auxiliary agent microcapsule dyeing new technology (patent: microcapsule disperse dye colouring method, Chinese patent publication number: 1443894).According to this new technology, dye microcapsule fully exchanges under 100 ℃～130 ℃ temperature with WATER AS FLOW MEDIUM in the switch room, high-temperature water enters microcapsules dissolves the dyestuff in the capsule, and the dyestuff of dissolving forms the saturable dye aqueous solution again to external diffusion, this solution circulated contacts with polyester fiber, in fiber surface absorption, form monomolecular adsorption layer, and further spread, dying to fibrous inside, the process of so dissolving, spread, adsorbing and dying continues to carry out, and finishes until dyeing.After reaching the dyeing of required dye level and finishing, cut off dyestuff capsule exchange system, do not have dyestuff this moment again in the dyeing system additional, the dye coating that fiber surface absorption is only arranged, proceed hungry dyeing some minutes, as 100～130 ℃ of insulations 10 minutes and even 30 minutes, make the loose colour of fiber surface enter fiber fully and dye oven dry.
In the occasion of traditional dyeing, also can adopt technology of the present invention with replace thereafter the reduction washing, soap, washing etc., also can save considerable rinsing water, and reduce sewage discharge effectively.Just should remove most auxiliary agent earlier after the dyeing, as utilize pressure rolling, centrifugal, simple rinsing etc., make that water does not have micella in hunger dyeing to form, thereby get rid of solubilization, make the loose colour of fiber surface have only an outlet---enter fiber.After the textile dyeing, can in high temperature-pressure dyeing machine, carry out hunger dyeing 10～30 minutes to remove most of auxiliary agent preliminary treatment,, improve every COLOR FASTNESS, dry then to remove removal floating color fully at 100～130 ℃ through dehydration or light rinsing simply.
As described, a kind of method of exempting the disperse dyeing of washing of the present invention comprises the technology that adopts DISPERSE DYES that the dyeing of hydrophobic fibre, a small amount of clear water are washed/dried, through after the above-mentioned disperse dyeing without washing, soap or reduce washing, by or not by pressure rolling, centrifugal and simple rinsing, 100～130 ℃ are incubated 10～30 minutes in clear water or recycle-water, oven dry.As adopt common disperse dyeing, through following PROCESS FOR TREATMENT: dyeing, a small amount of clear water are washed/are dried, after the disperse dyeing in clear water, bath raio is at 10: 1～50: 1,100～130 ℃, be incubated 10～30 minutes, dry.As adopt the microcapsule disperse dye colouring method, after the microcapsule disperse dye dyeing, clear water is washed/is dried, directly drops in the recycle-water on a small quantity, the bath raio that continues dyeing was at 10: 1～50: 1,100～130 ℃ are incubated 10 minutes and even 30 minutes, make the loose colour of fiber surface enter fiber fully and dye oven dry.
The present invention is applicable to the dyeing post processing of all hydrophobic dyes to hydrophobic fibre, as hydrophobic fibre and goods thereof such as various types of DISPERSE DYES and polyester, polyolefin, polyamide, polyacrylonitrile.Every after tested index has met or exceeded the fastness requirement of above two kinds of technologies after washing.
