Description
Technical field
The present invention relates to the dyeing and finishing manufacture field of weaving face fabric, particularly relate to a kind of colouring method of super imitative cotton silk blend fabric.
Background technology
Real silk owing to thering is good gloss, remarkable drapability, to add that sense of touch relaxes soft, wears light comfortablely, hygroscopicity, poisture-penetrability, aeration are good simultaneously, always are called as the king of fiber.The uvioresistant effect of real silk, with the good biocompatibility of skin, and the health care of cocoon fiber is that any fiber is all incomparable, irreplaceable.Cocoon fiber belongs to protein fibre, contains necessary 18 seed amino acids of human body, very nearly the same with the amino acid that human body skin is contained.Cocoon fiber not only has heat dispersion preferably, also has good warmth retention property.Also have that the defence pernicious gas is invaded, the opposing harmful bacteria, and vigor that can also reinforcement human epidermal skin cell, promote the metabolism of Skin Cell, some skin disease is had to good auxiliary therapeutic action simultaneously.In addition, because it has special hygroscopicity and gas permeability, also have the effect of regulate body temperature, adjusting moisture, thereby real silk is always a kind of textile material of top grade.
The traditional colouring method of real silk fabric is to adopt acidity or acid mordant dyes to be dyeed, and sometimes also adopts once in a while in addition direct dyeing.The dyeing of employing weak acid dye, although its DYED FABRICS color and luster is bright-coloured, fastness is poor; Although, and neutral dyeing fabric fastness is better, color and luster is bright-coloured not; Direct dyes are mainly used in making up the defect that the ACID DYES chromatogram is incomplete.No matter be domestic market or overseas market at present, more and more high to the COLOR FASTNESS requirement of real silk, thereby, with ACID DYES or acid mordant dyes dyeing, often do not reach requirement.And the REACTIVE DYES lovely luster, easy to use, chromatogram is complete, be a unique class can with the chemically-reactive dyes of cocoon fiber with covalent bonds, the bond energy of its covalent bond is much larger than hydrogen bond, Van der Waals force, thereby dyeing silk fabric on the application of active dyestuff, the colouring problem that can fundamentally solve real silk fabric.In addition, REACTIVE DYES is bright-colored, and dyefastness is high, and can adapt to the requirement of silk product to vividness.
Polyester fiber often is used to prepare silk-like fabric, by the synthesis modification polyester, adopt special spinning and dyeing and finishing technology, produces texture and looks and make price greatly reduce by also very smooth fiber of, feel closely similar with real silk.For the problem of the low temperature dyeing that solves polyster fibre, reduce the dyeing temperature of polyster fibre, realize boiling dyeing at normal pressure, the spinstry persons have carried out a large amount of exploitations and exploration, and obtain certain achievement.Commercially available modified polyester disperse dyeable under normal pressure (EDDP) although can obviously reduce the dyeing temperature of DISPERSE DYES, often will just can be obtained deep colour dyeing effect preferably during actual dyeing under surpassing 100 ℃ at present; And the dyeable modified terylene of cation dyes normal pressure (ECDP) is applied to Silk-Polyester BLENDED FABRIC piece dyeing when dyeing, still can't resolve the difficult problem of two kinds of fiber co-bathing dyeings, the general two-bath process that adopts, but also there are a lot of deficiencies in this method, for example dyeing flow is long, and after stock-dye, intensity often has obvious decline, and product quality is low, energy resource consumption is large, and cost is high.Although the dispersible cationic dyestuff of releasing in the market can be alleviated some problems in actual dyeing, but still can not fundamentally solve the problem of two kinds of fiber piece dyeing property.
In the face of cotton resource, supply falls short of demand, and the remaining situation of terylene production capacity relative rich, a lot of enterprises and institutions and colleges and universities have carried out in depth research and development to super imitative cotton product, and make great progress, particularly country is since starting " 12 " national science and technology supporting plan project " super imitative cotton synthetic fiber and the exploitation of textiles industrialization technology thereof " end of the year 2010, the exploitation of the super imitative cotton product of China makes great progress, the progressively industrialization of its achievement.Although super imitative cotton is a kind of modified poly ester product, but it has good characteristic cotton and terylene concurrently, reach imitative cotton like the cotton effect of cotton, imitative cotton victory, excellent flexibility, warmth retention property are arranged, also have good mechanical property, heat resistance, COLOR FASTNESS, even possess antistatic, anti-fluffing and anti-pilling, antibiotic, far function, it is the textile material of a class top grade, be used in high-grade sportswear, estimated in the near future, the novel high-grade fibers of this class will certainly become a kind of textile material of main flow.
Summary of the invention
The defect existed for prior art, the invention provides a kind of colouring method of super imitative cotton silk blend fabric, it can make dyeing and color control simple, have that the dyestuff dye-uptake is high, degree of fixation is high, the color depth of product promotes large, COLOR FASTNESS is high, the cloth cover cleaning, neither can destroy structure and the performance of real silk and copolyester fiber, can guarantee again the dyeing of two kinds of fibers.In addition, this process using one-bath dyeing, with short production cycle, energy resource consumption is low, and production cost is little, can meet small lot batch manufacture, the requirement of many kinds.
Described super imitative cotton is by the high-hydrophilic polyester slice after dry 12 hours, and after melt spinning, stretching and post processing, the filament number of acquisition is 0.8～1.5dtex, the modified polyester fiber that regain is greater than 2.2%.
The feature of described high-hydrophilic polyester slice is at least to contain other comonomer on its strand, hydroxyl ethyl esters as two as M-phthalic acid-5-sodium sulfonate, polyethylene glycol and polyalcohol etc., and the surface contact angle of copolyester section is greater than 55 °.
For achieving the above object, the present invention adopts following technical scheme:
A kind of colouring method of super imitative cotton silk blend fabric, comprise the steps:
1) super imitative cotton silk blend fabric is placed in to dye bath, after the weight ratio that is 1:20～40 according to bath raio adds water, adds dyestuff, levelling agent, glauber salt and glacial acetic acid, 10～30min turns round after being warmed up to 40～50 ℃ with the speed of 1～2 ℃/min;
2) speed with 1～3 ℃/min is warmed up to 90～100 ℃, after the 40～60min that turns round, and whole dyeing residual liquids of draining;
3) weight ratio that is 1:20～40 by bath raio adds clear water, with the speed of 2～4 ℃/min, is warmed up to 70～80 ℃, and the 10～20min that turns round adds continuously alkaline agent, then fixation 30～60min in 30～40min;
4) discharge water after dropping to 50～60 ℃ with the speed of 2～4 ℃/min, the clear water washing, the method that then adopts this area to know altogether soaps, washes, dry by dry after dyeing and weaving thing or finishing functions.
Said dyestuff is reactive dye for wool and DISPERSE DYES, and the addition of dyestuff needs definite according to color matching, and in the gross weight of super imitative cotton silk blend fabric, the addition of preferred dyestuff is for being greater than 0 to 5%.
Described alkaline agent is a kind of in soda ash or sodium bicarbonate or their mixture, and in the gross weight of super imitative cotton silk blend fabric, the levelling agent consumption is 0～2%, and the glauber salt consumption is 0～10%, and the alkaline agent consumption is 3～10%.
Described DISPERSE DYES be by super imitative cotton fiber respectively after 80 ℃ and 110 ℃ of dye tests, dye to obtain the coloured light of sample under different temperatures by duplicate, filter out suitable dye super imitative cotton redness, yellow and blue disperse dye.
Described levelling agent is A Baige B, is Si commercially available prod, vapour Bagong.
Preparing super imitative cotton Modified polyester chips used is generally on the binary monomer basis of normal polyester fiber, a small amount of the 3rd monomer, the 4th monomer have been increased, even more eurypalynous other comonomer, function monomers such as the two hydroxyl ethyl esters of M-phthalic acid-5-sodium sulfonate (SIPE), polyethylene glycol (PEG) is as comonomer, select suitable process conditions, polymerization modified copolyester out.Style and feature according to cotton fiber, use modern spinning process, for example in spinning chips, add a small amount of functional stuffing, the thin dawn, the fiber abnormity, the technology such as cavitation, gloss and the Fabric Style of simulation cotton, the chemical fibre prepared, make this fiber that excellent flexibility not only be arranged, the performances such as warmth retention property, also has good mechanical property, heat resistance and COLOR FASTNESS, make as required long filament and the short fiber of different fiber numbers, this super imitative cotton technology of preparing is ripe, antistatic cation dyeable polyester composition and method of making the same as a kind of as Chinese patent (CN 103073710 A).This fibrid is compared with the normal polyester fiber, and the structure of fiber is more loose, and degree of crystallinity is lower, and the degree of orientation is lower, and introduced many and dyestuff has and more pretend group firmly simultaneously.Due to the variation of the molecule segment of having introduced other type and fibre structure, thereby this fiber is the same with real silk, and non-refractory, generally dyeed by cation dyes, rather than adopts DISPERSE DYES.We are by a large amount of dye tests, find differently from conventional polyester, owing in super imitative cotton fiber, containing sulfonic group, on the fraction DISPERSE DYES is suitable for, do not dye this kind of fiber, with tinctorial, carry out, and dye to such an extent that serious skew can occur for the coloured light of sample.But as long as, in advance through screening, a part of DISPERSE DYES stands good in super imitative cotton dyeing, and maintenance coloured light is constant in wider pH value scope.
Cocoon fiber has its unique performance, because acidic-group (as-COOH) and basic group are contained freely (as-NH in the side chain on the large molecule of cocoon fiber and backbone molecule two ends
2), protein molecule not only can be ionized as acid but also as alkali, so cocoon fiber possesses amphotericity.When isoelectric state (the pH value is generally between 3.5 to 5.2), fiber removes and presents complete non-ionizing form, is mainly carboxyl and amino simultaneously from the form existence of separating and accept proton in molecule.REACTIVE DYES can go up the dyeing silk fiber under faintly acid, neutrality or weak basic condition, and under solutions of weak acidity, REACTIVE DYES mainly is combined with fiber by hydrogen bond, Van der Waals force and ionic bond, and wet colour fastness is poor; Under neutrallty condition, dyestuff except being combined by hydrogen bond and Van der Waals force, also has a small amount of covalent bonds with fiber; Under weak basic condition, in dyestuff and cocoon fiber-OH ,-NH
2react, mainly be combined with cocoon fiber by covalent bond, wet fastness is fine.Because the cocoon fiber alkali resistance is poor, therefore while dyeing, in the pH value, in higher dye bath, dye, when especially dyeing temperature is higher, usually can affect gloss and the feel of real silk.Yet while dyeing in acid bath, with the REACTIVE DYES of anionic charge, be easy to ionic bond, combination occur with cocoon fiber, this is the main cause that in acid bath, REACTIVE DYES has very high dyestuff dye-uptake.Still have covalent reaction amino and cocoon fiber under acid condition, but the amino content on cocoon fiber very low (0.2mol/kg), therefore the covalent bonds under acid condition is limited.And dye in alkaline bath, the amino on cocoon fiber and hydroxyl oxygen anion react with the nucleophilic displacement of fluorine (or addition) of active group in dye molecule, with covalent bonds.Adding of alkaline agent is conducive to cocoon fiber-NH
2existence and cocoon fiber-OH be ionized into negative oxygen ion, thereby be conducive to dyestuff and fiber with covalent bonds, first high-temp dyeing under acid condition in the present invention, the dyeing that then adds at a lower temperature the alkali fixation fully takes into account this point just.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the dyestuff dye-uptake of REACTIVE DYES and DISPERSE DYES is high, and COLOR FASTNESS reaches 3～4 grades.Wherein the dye-uptake of REACTIVE DYES can bring up to 80～99%, and degree of fixation reaches 65～80%, and the dye-uptake of DISPERSE DYES surpasses 90%, and the color depth of product at least can promote more than 15%, saves dyestuff 10～20%.
(2) super imitative cotton and silk blend fabrics feel soft provided by the present invention, the cloth cover cleaning, the fiber resilience is good, and dyeing course is little to the loss of super imitative cotton and real silk brute force.
(3) be conducive to improve the dye-uptake of REACTIVE DYES in acid hot conditions dyeing, DISPERSE DYES completes diffusion, diffusion and the fixation process of dyestuff, and dyestuff can go deep into fabric and fibrous inside, can be by the heavily fabric imbue; Add continuously the alkali fixation at cryogenic conditions, due to Dye Adsorption, on fiber, can make alkaline agent more be taken full advantage of, obtain higher fixation efficiency, also can effectively alleviate DISPERSE DYES, real silk and super imitative cotton destruction or damage simultaneously, cloth cover is more clean.
(4) colouring method of super imitative cotton silk blend fabric provided by the invention, the mode of employing co-bathing dyeing, do not need in dyeing course to use any carrier analog assistant, and with short production cycle, energy resource consumption is low, and production cost is little.Simultaneously, the raising of dyestuff dye-uptake and degree of fixation, reduced residual liquid discharge concentration, and loose colour reduces greatly, and the raising of COLOR FASTNESS alleviates the intensity of soaping, and effectively reduces the total release of sewage, is conducive to environmental protection, can meet small lot batch manufacture, the requirement of many kinds.
