Description
(1) technical field
The present invention relates to a kind of dye selection at wool/copper ammonia fiber blended fabrics dyeing, and the dye selection of corresponding auxiliary agent of complex dye in dyeing, supporting dyeing, aftertreatment technology.Belong to the stock-dye technical field.
(2) background technology
Wool/copper ammonia fiber blended fabrics is that to prop up non-twist copper ammonia fibre long filament with height be warp thread, and the WORSTED single thread is the blended yarn woven fabric that weft yarn is produced.Lining have feel sliding glutinous, gloss is charming, color and luster is elegant, drapability is good and the characteristic of unique style.
Copper ammonia fibre is a kind of regenerated celulose fibre, it is that loose natural cellulosic feedstocks such as cotton linter are dissolved in the liquor ammoniae fortis of Kocide SD or alkaline cupric salt, be made into spinning solution, after filtration with deaeration after, solidification forming in the spinning bath of water or dilute alkaline soln makes the plain molecular compound of copper ammonia fibre take place to decompose and the cellulose of regenerating again in containing second body lotion of 2%～3% sulfuric acid solution.The hydrate cellulose fiber that generates is handled the vestiges of removing copper with pickle again through water washing, after this oils and dry and form through washing again.Its discarded object decomposes easily, meets the ecological, environmental protective requirement.Copper ammonia fibre has meeting breathing, salubrious, antistatic and drapability good four big functions.The fibre section sub-circular, the intensity height, color is pure white, and gloss is soft pleasing, and is soft; Porous surface does not have cortex, so superior dyeability is arranged, moisture absorption, suction; Its fibre density is big than real silk, terylene etc., therefore has the sense of dangling; Its regain is higher, is only second to wool, and is suitable with silk, and is higher than cotton and other chemical fibre, thereby moisture absorption efficient height.The purposes of copper ammonia fibre is the same substantially with viscose, but its wearability is splendid, is similar to silk.A high non-twist copper ammonia fibre long filament is because no twist is in no obvolvent state between each single yarn, when weaving yarn through heald, reed, yarn is wear and rupture very easily, causes fabric defects and weaves difficulty, so weaving preceding starching, increase the cohesive force between the single thread, satisfy woven demand.
Wool is elongated solid cylinder, is curling shape, and the institutional framework of fiber is divided three layers, i.e. scale layer, cortical layer and medullary substance layer.The main component of wool is a keratin, and it is made of the surplus base of multiple a-amino acid, and the latter can be coupled to helical long-chain molecule, contains carboxyl, amido and hydroxyl etc. on it, at intermolecular formation salt type bond and hydrogen bond etc.The cross linkage that is formed by the disulfide bond of cystine between the long-chain connects mutually.The characteristic of above-mentioned chemical constitution decision wool.Carry out the transition to β type extended pattern by α type spirality when being subjected to force-extension as the big molecule long-chain of wool fibre, return to the α type again after external force is removed, then to show as the elongation strain and the resilience of wool good for its outward appearance.The wettability power that wool is stronger is relevant with some groups on the long-chain.Wool is more acidproof and not alkaline-resisting, and alkali is not only to making wool generation hydrolysis, and makes disulfide bond and salt type bond fracture, sulfur content in the wool fibre is reduced, cause mechanical performance declines such as wool intensity, the fiber jaundice, feel is coarse, and degree of injury is by character, concentration, the temperature and time decision of alkali.Oxidant also can destroy disulfide group and damage wool.
Wool/copper ammonia fiber blended fabrics normal dyeing method is: adopt the dyeing of two bath methods, dye under acid condition with mordant dyes when dyeing wool is generally produced, acidity is stronger, but copper ammonia fibre is not acidproof, and damage is bigger in dyeing course; And REACTIVE DYES is adopted in copper ammonia fibre dyeing, needs stronger alkaline fixation, and this will damage wool again, and two bath method dyeing times reach 9-10 hour, and it is very big to the damage of lining to be in acidity or alkali condition for a long time.
Conventional REACTIVE DYES is a kind of high activity dyestuff, and permeance property is relatively poor in dyeing course, and in blended yarn woven fabric dyeing, the penetrating power of difference has reduced the uniformity of dyeing.Most of REACTIVE DYES all has the trend of hydrolysis, especially when high-temp dyeing, but Comparatively speaking, the high activity dyestuff than in SA dyestuff facile hydrolysis more, the hydrolysis meeting of active group reduces the fixation ability of dyestuff, thereby influence big sample difference after the textile dyeing, and the stability of textile dyeing and dyeing reproducibility.
(3) summary of the invention
The objective of the invention is to: at first at the dyeability of wool and copper ammonia fibre, select a kind of dyestuff that wool/copper ammonia fiber blended fabrics is carried out one-bath dyeing, reduce the damage of lining in dyeing course, secondly in dyeing course, select proper auxiliary agent, improve Color, make a whole set of rational and effective dyeing then, improve the homochromatism and the uniformity of dyed shell fabrics, reduce the damage of lining, improve Color and COLOR FASTNESS.
The object of the present invention is achieved like this: Lan Nasu (Lanasol) dyestuff of selecting U.S.'s Hensel to step the production of weaving dying (China) Co., Ltd carries out one-bath dyeing, reduces the damage of dyeing to lining.
Lan Nasu is a kind of reactive dye for wool, its active group: the nucleophilic addition of two keys both can take place in a-bromo-propylene ammonia, the nucleophilic substitution of bromine atoms also can take place, so bluely theoretically receive the plain acid dyeing that both can be used for wool, also can be used for the basic dyeing of cellulose fibre.Though it is lower that orchid receives uniformly dyeing material dye-uptake to cellulose dyeings such as viscose glues the time, but it is different with viscose glue, the cross section of copper ammonia fibre is rounded, no skin-core structure, and smooth surface, cohesive force is poor between fiber, this makes dyestuff can be relatively easy to be penetrated into fibrous inside, engage with the fiber generation, can obtain dye-uptake preferably, obtain darker color.Lan Nasu is a kind of low activity dyestuff, and the low activity dyestuff has permeance property preferably in dyeing course, and in blended yarn woven fabric dyeing, good penetrating power can effectively improve the uniformity of dyeing.Most of REACTIVE DYES all has the trend of hydrolysis, especially when high-temp dyeing, but Comparatively speaking, the low activity dyestuff than in highly active dyestuff facile hydrolysis not, the hydrolysis meeting of active group reduces the fixation ability of dyestuff, thereby influence after the textile dyeing sample difference greatly, and the stability of textile dyeing and dyeing reproducibility, adopt the low activity dyestuff can reduce big sample difference after the textile dyeing, improve dye stability and reappearance.
In dyeing course, add U.S.'s Hensel and step the A Bairun C of weaving dying (China) Co., Ltd exploitation as crease-resistant lubricant, can make fabric face form fluidized bed, reduce the friction between fabric and the fabric, improve the level dyeing performance, be difficult for forming permanent crease; Prevent the adhesion between the fabric fiber, can make between fiber displacement easy, fundamentally reduced the generation of wrinkle, improved fabric elasticity, improved feel, and A Bairun C has no effect to dyeing.Because wool has scale layer, dyestuff is difficult for being penetrated into fibrous inside, the FFC-01 so the penetration enhancer A Bai that adding U.S. Hensel weaving advanced in years dying (China) Co., Ltd produces when dyeing disappears, the A Bai FFC-01 that disappears has the performance of froth breaking, degasification and infiltration concurrently, removal is because of surfactant or handle the bubble that the air in bathing produces, fabric is run well reliably, prevent the generation of color dot color spot, promote the fabric face level dyeing, and evenly dye liquor is layered on fabric face rapidly, promotes that dye liquor is deep and thorough to fabric.
Wool belongs to protein fibre, and copper ammonia fibre belongs to cellulose fibre, and both have very big difference on morphosis, physics and chemical property, so cause the notable difference of both dyeabilities, need rebulid a cover dyeing technology, technology was divided into for two steps: dyeing and post processing.
The first step, dyeing
With the wool/copper ammonia fiber blended fabrics overflow dyeing machine of packing into, turned round 5-10 minute, add the glacial acetic acid of the heavy percentage of 0.1-0.3% fabric, make dye bath pH value 5.5-6.5 (deciding), turned round 5-10 minute according to dye dosage, add the 0.5-1g/L A Bai FFC-01 that disappears, turned round 5-10 minute, and added the white and moist C of 1-2g/L Ah, turned round 5-10 minute, add 15-30g/L glauber salt (deciding) according to dye dosage, turned round 10-20 minute, and added orchid and receive the uniformly dyeing material, turned round 5-10 minute, begin to heat up, heating rate remains on 0.5-1 ℃/minute, 90 ℃ ± 2 ℃ insulations 20-30 minute, cools to 70 ℃ ± 2 ℃ then, add 3-5g/L soda ash, be incubated 50-70 minute.Bath raio: 1: 15-20.
When hydrogen ion number in the dye liquor increased, amino ion populations increased; When the hydrogen ion number reduced, then amino ion populations reduced, and added glacial acetic acid, and pH value reduces, and dye liquor is acid to be strengthened, and dyed (a NH on the wool
2Adsorb a H
+And change into-NH
3+) increase, thereby increased the probability that dyestuff combines with wool, improved the dyestuff dye-uptake, dye liquor pH value is low excessively, dyestuff is to the dye-uptake height of wool, under acid condition, copper ammonia fibre is competed the ability of dying well below wool to dyestuff, the dye-uptake height of wool then copper ammonia fibre on dye poor, the homochromatism of fabric is also just poor, and copper ammonia fibre is not acidproof, and low excessively pH value can cause the damage of copper ammonia fibre, so control dyeing pH value is at 5.5-6.5 (consumption according to dyestuff is decided); Wool has scale layer, and temperature is crossed low dye and is difficult to be diffused into fibrous inside by scale layer, and the too high words of temperature, dyestuff also can improve the dye-uptake of wool, will reduce dying on the copper ammonia fibre, reduce the homochromatism of lining, so the temperature of acid dyeing is fixed on 90 ℃ ± 2 ℃; In dyeing course, add glauber salt, can overcome or reduce the electrostatic repulsion between dyestuff anion and copper ammonia fibre surface, make the dyestuff ion easily near going up copper ammonia fibre with absorption; The Na ion concentration that increases in the dye liquor body can also reduce dye liquor body and near the concentration of fiber interface, thereby reduce owing to hindering that concentration difference produces, improve the substantivity of dyestuff to copper ammonia fibre, improve the dye-uptake of dyestuff to copper ammonia fibre, and raising along with the glauber salt consumption, dyestuff also obviously improves the substantivity and the dye-uptake of copper ammonia fibre, and in order to guarantee the homochromatism of lining, the glauber salt consumption is between 15-30g/L; Because orchid receives the uniformly dyeing material and belongs to salt control type dyestuff, activity is lower under alkali condition, therefore the color fixing temperature that needs is higher relatively 70-85 ℃, certainly required fixation alkali consumption is also just less relatively, because wool is damage easily under alkali condition, degree of injury is by character, concentration, temperature, the time of alkali, so in order to reduce the damage of wool in dyeing, adopt the more weak soda ash of alkalescence at 70 ℃ ± 2 ℃ fixation, soda ash consumption 3-5g/L.
Second step, aftertreatment technology
Wool/copper ammonia fiber blended fabrics after the dyeing is placed the liquid 209 of soaping of the heavy percentage of 2-5% fabric earlier, the soda ash that adds the heavy percentage of 2-3% fabric, handle 20-30min for 80-90 ℃, place the glacial acetic acid of the heavy percentage of 0.2-1% fabric after the flushing again, handle 10min for 40 ℃ ± 2 ℃.Bath raio: 1: 15-1: 20.
On the wool/copper ammonia fiber blended fabrics after the dyeing except containing the dyestuff that combines with fiber, the loose colour and the hydrolised dye that also contain absorption, if flush away not, the desorb meeting of these dyestuffs causes the staining of consumer's other fabrics when washing, so use 80-90 ℃ the liquid 209 of soaping to wash thoroughly flush away loose colour and hydrolised dye at alkali condition; Handle with glacial acetic acid at last, regulate the pH value, smooth to guarantee that subsequent technique is handled.
The present invention adopts orchid to receive the uniformly dyeing material wool/copper ammonia fiber blended fabrics is carried out one-bath process, reduce dyeing time, reduce the damage of lining, select proper auxiliary agent to improve Color, and formulate corresponding dyeing and aftertreatment technology, improved homochromatism, dyeing uniformity and the stability of dyeing, Color is good, and COLOR FASTNESS is good.And the damage to lining is little in dyeing course.
