The reactive dyes dyeing method of cellulose fiber yarn
Technical field
The present invention relates to the textile printing and dyeing field, relate in particular to dyeing and finishings knitting, the used dyed yarns of lining such as look is knitted, cowboy and handle.
Background technology
The dyeing of lining dyed yarns used, that contain cellulose fiber ingredients such as knitting, look is knitted, cowboy, as contain cotton, contain the dyeing of dyed yarns such as viscose glue, staining techniques such as hank dyeing, cheese dyeing, beam dyeing, sizing-dyeing machine dyeing adopted usually.Water consumption is big, power consumption is high because these staining techniques have, sewage discharge heavily waits significant disadvantages, the continuous knot dyeing technology of the cellulose fiber yarn that water consumption is little, production efficiency is high obtain the printing and dyeing primary study on boundary.
Patent of invention " a kind of production method of pigment dyed colored cloth " (patent No. 200610085843.1) is with the example of application of paints in the continuous knot dyeing technology of cellulose fiber yarn.In this The Application of Technology, coating can not effectively be penetrated into yarn fibers inside, causes tangible technology and quality problems thus: the one, and dyefastness is poor, and particularly crock fastness is poor, can only produce to be used for ready-made clothes polishing, the required yarn in washing aspect; The 2nd, it is poor that the core degree is passed through in dyeing; The 3rd, dye-uptake is low, and difficulty is high when dying dark color, quality is unstable, and it is serious that adhesive is stained with roller.
For cellulose fibre; REACTIVE DYES pass through on core degree and the dye-uptake in dyefastness, dyeing has more performance than coating; And cost is lower, and the continuous knot dyeing that REACTIVE DYES is applied to the cellulose fiber yarn is technological, will help to overcome the above problems.REACTIVE DYES are main the employing and the diverse dip method of continuous knot dyeing on yarn dyeing at present; Like hank dyeing, cheese dyeing, beam dyeing etc.; Though and the continuous knot dyeing method is mainly adopted in the dyeing of REACTIVE DYES on lining, the REACTIVE DYES continuous knot dyeing method of dyeing fabric mainly comprises two kinds of technologies, and a kind of is the curing fixation method; Be applicable to that mainly the K type dye dyes light color; The REACTIVE DYES, chromatogram that are not suitable for other types are complete, can not dye dark color, and baking temperature requires to reach more than 170 ℃, and this has seriously limited the application of this color-fixing method in cellulose fiber yarn continuous knot dyeing; Another kind is the vapour steaming colour fixing method; The dyeing object is behind exhaust dyeing solution; Immerse fixation liquid again and realize fixation through decatize; This method itself has problems such as the dyestuff hydrolysis is many, chroma in waste water height, as the fixation that the is used for yarn special-purpose yarn decatize case of needs also then, and exists and broken yarn takes place in the decatize case be difficult to difficult problems such as disposal.Therefore, REACTIVE DYES are applied in the continuous knot dyeing of cellulose fiber yarn, also lack effective process at present.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide a kind of process that is suitable for the employing reactive dyeing of cellulose fiber yarn continuous knot dyeing.
The technical scheme that the present invention adopted is: a kind of reactive dyes dyeing method of cellulose fiber yarn; Warping is become the yarn of axle; Mode with continuous knot dyeing; Pass through following technology successively: pad cation-modified solution process, stoving process, exhaust dyeing solution process, stoving process, bake technology, washing process, stoving process; Wherein, adopt drying cylinder to carry out with the mode that contact bakes in the technical process described baking, described yarn directly contacts with the high temperature outer tube wall of drying cylinder.
Preferably, cation-modified solution contains cation modifier 1~50g/L, alkaline agent 1~50g/L, bleeding agent 1~10g/L.
Preferably, the staining solution that pads is that reactive dyeing solution or coating REACTIVE DYES are bathed staining solution altogether.
Preferably, the described process conditions that bake technical process do, 150~170 ℃ of baking temperatures, bake 1~2 minute time.
The applicable object of this technical scheme is the yarn that contains cellulose fibre; Comprise that whole compositions are purified cotton yarns, viscose glue yarn, TENCEL YARNS line, bamboo fibre yarn, model yarns of cellulose fibre, perhaps two kinds or more kinds of blending or yarn interlaced in cotton, viscose glue, day silk, bamboo fibre, the model; Perhaps all compositions are cellulose fibre and other fiber blends or yarn interlaced, like one or more fiber blends or the yarn interlaced in cellulose fibre and terylene, polyamide fibre, acrylic fibers, spandex, wool, the fiber crops.
The inherent mechanism of technical scheme that the present invention adopts is: after the cellulose fiber yarn pads cation-modified solution; Dye on the cellulose fibre on the cation-modified agent molecule and be penetrated into cellulose fibre inside; And then be grafted on the cellulose fibre, and make the lotus that becomes positively charged after the cellulose fibre grafting through chemical reaction.This makes cellulose fibre when padding the solution of REACTIVE DYES, can and impel on the REACTIVE DYES and dye because of the REACTIVE DYES of the effective adsoption band negative electrical charge of attracting each other of positive and negative charge, and and then the combination that produces chemical bond.The process that this chemical bond combines is exactly the fixation process; Because chemical reaction mainly is cation modifier group and the chemical bond between the REACTIVE DYES that is grafted on the cellulose fibre in this fixation process; Be different from that the fixation process mainly is the chemical bond between cellulose fibre and the REACTIVE DYES in the conventional reactive dyeing; Therefore this fixation is handled under 150~170 ℃ high temperature and can be accomplished in 1~2 minute; Do not need auxiliary agents such as salt, urea, glauber salt to urge the effect of dying, do not need this color fixing condition of decatize of high humility yet.
The invention has the beneficial effects as follows: the continuous knot dyeing of cellulose fiber yarn can use REACTIVE DYES to dye; And baking temperature is relatively low, the mode that bakes is simple in the dyeing; Few and the operative employee of broken yarn handles easily, thereby is particularly suitable for unique requirement of yarn continuous pad dyeing.Compare with the curing fixation method of existing dyeing fabric, restriction, the chromatogram that on dyestuff uses, breaks through K type REACTIVE DYES is complete, dyestuff select for use scope wide, dark in light color can dye; Compare with the vapour steaming colour fixing method of existing dyeing fabric, make used additives simple, save auxiliary agents such as salt, urea, glauber salt, the dyestuff hydrolysis is few, chroma in waste water is low, and it is little that dyeing quality is stable, difference is criticized in front and back.
