Description
Technical field
The present invention relates to a kind of dye selection at copper ammonia fibre dyeing, and in slub dyeing dye corresponding dyeing, aftertreatment technology of complex dye.Belong to the stock-dye technical field.
Background technology
Along with development of times, the progress of science and technology, people's living standard also improves thereupon, quality of life also there has been higher requirement, old fabric lining can not satisfy the demands, and a collection of wearability fiber better, more compliance with environmental protection requirements has produced, and copper ammonia fibre is exactly one of them.
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, 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.
Summary of the invention
The objective of the invention is to select a kind of suitable copper ammonia fibre slub dyeing, Color is good and in dyeing course, copper ammonia fibre is damaged little dye well dyeing.
The object of the present invention is achieved like this: a kind of dyeing of copper ammonia fibre is characterized in that it is to adopt orchid to receive element to make dyestuff.
The dyeing of copper ammonia fibre of the present invention, described orchid are received and plain are produced by Switzerland Ciba company.
Lan Nasu is a kind of low activity dyestuff.The molecular structure of REACTIVE DYES and ACID DYES and simple direct dyes similar just increased active group in the molecule.The primary structure of REACTIVE DYES has chromogen, water-soluble sulfonic group, active group and connects base.The basic directly connection of connection active group is with chromophore or be connected active group and other parts of dye molecule.In these structures any one all can influence dyeability and fastness ability.Various dissimilar REACTIVE DYES have different chemical constitutions, and very big field of activity is arranged.Active different, the effect difference of in dyeing course, bringing into play, the low activity dyestuff has fiber pervasion performance preferably in the reactive dyeing process, and in slub dyeing, good penetrating power can effectively improve the uniformity of dyeing.Most of REACTIVE DYES all has the trend of hydrolysis, 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 big sample difference after the textile dyeing, and the stability of stock-dye and dyeing reproducibility, adopt the low activity dyestuff can reduce big sample difference after the textile dyeing, improve dye stability and reappearance.So the SA orchid that we select Switzerland Ciba company to produce receives the uniformly dyeing material.The active group of this dyestuff: the a-bromo-activity of propylene ammonia is lower than the active group of other common on the market several REACTIVE DYES: difluoro one chlorine pyrimidine, vinyl sulfone(Remzaol derivative, a chloro-s-triazine, dichloro s-triazine etc.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 the acid dyeing that is used for wool in actual production, has adopted acid dyeing technology equally when dying cellulose fibre, and effect is undesirable, paint shallow, COLOR FASTNESS is poor.Because the nucleophilic addition of two keys both can take place in the a-bromo-propylene ammonia among the Lan Nasu, the nucleophilic substitution of bromine atoms also can take place, so orchid receives element and both can be used for acid dyeing theoretically, also can be used for basic dyeing.Copper ammonia fibre is dissolving easily in hot diluted acid, and diluted alkaline has only slight damage to it, so we consider to adopt orchid to receive plain basic dyeing technology, technology was divided into for two steps: dyeing and post processing.
The first step, dyeing
The copper ammonia fibre wool top pinecone is placed in the normal temperature top dyeing machine, begin to heat up by room temperature, heating rate 1-2 ℃/min, in the time of 40 ℃ ± 2 ℃, move 5-10min earlier, divide then and add the glauber salt that total consumption is 50-100g/L several times, each joining day is every 20-40min (deciding the length of blanking time) by the consumption of dyestuff, move 20-30min at 40 ℃ ± 2 ℃ after adding glauber salt, begin to heat up, heating rate keeps 0.5-1.0 ℃/min, handles 10min ± 5min at 80-85 ℃, divides then and adds the soda ash that total amount is 3-5g/L (determining the consumption of soda ash by the depth of color) several times, operation 30-70min, bath raio 1: 20-50.
In above-mentioned dyeing, can divide three times and add glauber salt, each 1/3 of total consumption that adds, add the soda ash that total amount is 3-5g/L then at twice, add 2/5 of total consumption earlier, operation 20-40min (deciding the length of blanking time by the consumption of dyestuff) adds total consumption 3/5 again, operation 10-30min.
Because orchid receives the uniformly dyeing material and belongs to salt control type dyestuff, activity is lower under alkali condition, and therefore the color fixing temperature that needs is higher, up to 80-85 ℃; Better direct, stronger to the affinity of fiber, dyestuff is adsorbed by fiber easily when neutrality is bathed, and in order to control level-dyeing property, the initial temperature of dyeing can not be too high, selects room temperature to rise and dyes; The adding of glauber salt helps improving the substantivity of dyestuff, but it is direct too high, influence the migration property energy of dyestuff again easily, cause the look flower,, add but divide several times so in dyeing course, do not adopt the method for disposable adding glauber salt, each certain interval of time, guaranteeing that dyestuff dyes on having higher substantivity when, can guarantee to carry out moving and dye to a certain degree, so not only guarantee the degree of depth of color but also can improve dyeing uniformity; After neutral-bath dyeing, by adding suitable type and a certain amount of alkali the dye bath pH value is raise, cause hydroxyl ionization on the copper ammonia fibre, nucleophilicity fiber ion and dyestuff reaction, copper ammonia fibre has slight damage under diluted alkaline, highly basic then can make its dissolving of expanding, thus select the more weak soda ash of alkalescence to carry out fixation, because that orchid receives plain activity is lower, required fixation alkali consumption is also less relatively, so only need the soda ash of 3-5g/L, in order to improve even dyeing effect, soda ash also needs to add in batches equally.
Second step, post processing
Copper ammonia fibre wool top after the dyeing is placed the liquid 209 of soaping of the heavy percentage of 2-5% fabric earlier, handle 20-30min for 90-100 ℃, 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: 20-1: 50.
On the wool top 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 the liquid 209 of soaping of boiling to wash thoroughly flush away loose colour and hydrolised dye; Handle with glacial acetic acid at last, regulate the pH value on the wool top, smooth to guarantee that subsequent technique is handled.
The low activity dyestuff orchid that the present invention adopts Switzerland Ciba company to produce receives plainly dyes to copper ammonia fibre, can improve dye exhausting rate, improve dyeing uniformity and stability, and Color is good.And it is little to the copper ammonia fibre damage in dyeing course.
