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 having good gloss, remarkable drapability, adding that sense of touch relaxes softness, is worn light comfortable, and hygroscopicity, poisture-penetrability, aeration well, are always called as the king of fiber simultaneously.The uvioresistant effect of real silk, the biocompatibility good with skin, and the health care of cocoon fiber is that any fiber is all incomparable, irreplaceable.Cocoon fiber belongs to protein fibre, containing necessary 18 seed amino acids of human body, very nearly the same with the amino acid contained by human body skin.Cocoon fiber not only has good heat dispersion, also has good warmth retention property.Also have that defence pernicious gas invades, opposing harmful bacteria, and can also the vigor of reinforcement human epidermal skin cell, promote the metabolism of Skin Cell, have good auxiliary therapeutic action to some skin disease simultaneously.In addition, because it has special hygroscopicity and gas permeability, also have regulate body temperature, regulate the effect of moisture, thus real silk is always a kind of textile material of top grade.
The traditional colouring method of real silk fabric adopts acid or acid mordant dyes to dye, and sometimes also adopts direct dyeing once in a while in addition.Employing weak acid dye dyes, 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 infull defect of ACID DYES chromatogram.No matter be domestic market or overseas market at present, require more and more high to the COLOR FASTNESS of real silk, thus with ACID DYES or acid mordant dyes dyeing, often do not reach requirement.And REACTIVE DYES is bright in colour, easy to use, chromatogram is complete, that a unique class can with cocoon fiber with the chemically-reactive dyes of covalent bonds, the bond energy of its covalent bond is much larger than hydrogen bond, Van der Waals force, thus dyeing silk fabric on application of active dyestuff, fundamentally can solve the colouring problem of 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 is often used to prepare silk-like fabric, by synthesis modification polyester, adopts special spinning and dyeing and finishing technology, produces the fiber that texture looks closely similar with real silk, feel is also very smooth, price is reduced greatly.In order to solve the problem of the low temperature dyeing of polyster fibre, reduce the dyeing temperature of polyster fibre, realize boiling dyeing at normal pressure, spinstry persons have carried out a large amount of exploitation and exploration, and obtain certain achievement.Modified polyester disperse dyeable under normal pressure (EDDP) commercially available at present, although obviously can reduce the dyeing temperature of DISPERSE DYES, often just will can obtain good deep colour dyeing effect during actual dyeing at more than 100 DEG C; And the dyeable modified terylene of cation dyes normal pressure (ECDP) be applied to Silk-Polyester BLENDED FABRIC piece dyeing dyeing time, still can't resolve a difficult problem for two kinds of fiber co-bathing dyeings, general employing two-bath process, but also there is a lot of deficiency in this method, such as 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 released in the market can alleviate some problems in actual dyeing, but still fundamentally can not solve the problem of two kinds of fiber piece dyeing property.
In the face of cotton resource, supply falls short of demand, and the situation more than terylene production capacity relative rich, a lot of enterprises and institutions and colleges and universities have carried out in depth researching and developing to super imitative cotton product, and make great progress, particularly country is since the end of the year 2010 started " 12 " national science and technology supporting plan project " super imitative cotton synthetic fiber and the exploitation of textiles industrialization technology thereof ", 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 that is cotton and terylene concurrently, reach the imitative cotton effect cotton like cotton, imitative cotton victory, there are excellent flexibility, warmth retention property, also have good mechanical property, heat resistance, COLOR FASTNESS, even possess antistatic, anti-fluffing and anti-pilling, antibacterial, far function, it is the textile material of a class top grade, be used in high-grade sportswear, estimate in the near future, this kind of novel high-grade fibers will certainly become a kind of textile material of main flow.
Summary of the invention
For the defect that prior art exists, the invention provides a kind of colouring method of super imitative cotton silk blend fabric, it can make dyeing and color controlling simple, have that dyestuff dye-uptake is high, degree of fixation is high, the color depth of product promotes large, COLOR FASTNESS is high, cloth cover is clean, both can not destroy the stuctures and properties of real silk and copolyester fiber, can ensure again the dyeing of two kinds of fibers.In addition, this technique adopts one-bath dyeing, and with short production cycle, energy resource consumption is low, and production cost is little, can meet small lot batch manufacture, the requirement of multi items.
Described super imitative cotton is that by high-hydrophilic polyester slice after dry 12 hours, 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 containing other comonomer on its strand, and as M-phthalic acid two hydroxyl ethyl ester-5-sodium sulfonate, polyethylene glycol and polyalcohols etc., the surface contact angle of copolyester section is greater than 55 °.
For achieving the above object, the present invention adopts following technical scheme:
A colouring method for super imitative cotton silk blend fabric, comprises the steps:
1) super imitative cotton silk blend fabric is placed in dye bath, after the weight ratio being 1:20 ~ 40 adds water, adds dyestuff, levelling agent, glauber salt and glacial acetic acid according to bath raio, with the ramp of 1 ~ 2 DEG C/min to running 10 ~ 30min after 40 ~ 50 DEG C;
2) with the ramp of 1 ~ 3 DEG C/min to 90 ~ 100 DEG C, running 40 ~ 60min after, whole dyeing residual liquid of draining;
3) weight ratio being 1:20 ~ 40 by bath raio adds clear water, and with the ramp of 2 ~ 4 DEG C/min to 70 ~ 80 DEG C, running 10 ~ 20min, adds alkaline agent continuously, then fixation 30 ~ 60min in 30 ~ 40min;
4) discharge water after dropping to 50 ~ 60 DEG C with the speed of 2 ~ 4 DEG C/min, clear water washs, and then adopts the method known altogether of this area to soap, 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 to determine according to color matching, and with the total 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 with the total weight of super imitative cotton silk blend fabric, levelling agent consumption is 0 ~ 2%, and glauber salt consumption is 0 ~ 10%, and alkaline agent consumption is 3 ~ 10%.
Described DISPERSE DYES is by super imitative cotton fiber respectively after 80 DEG C and 110 DEG C of dye tests, contaminates to obtain the coloured light of sample at different temperatures by duplicate, filters out the redness of the super imitative cotton of suitable dye, yellow and blue disperse dye.
Described levelling agent is A Baige B, is the commercially available prod of vapour Bagong department.
Preparing super imitative cotton Modified polyester chips used is generally on the dibasic monomer basis of conventional polyester fiber, add a small amount of Third monomer, the 4th monomer, other comonomer even more eurypalynous, the two function monomer such as hydroxyl ethyl ester-5-sodium sulfonate (SIPE), polyethylene glycol (PEG) of such as M-phthalic acid is as comonomer, select suitable process conditions, polymerization modified copolyester out.According to style and the feature of cotton fiber, use modern spinning process, such as in spinning chips, add a small amount of functional stuffing, the thin dawn, fiber abnormity, the technology such as cavitation, the gloss of simulation cotton and Fabric Style, the chemical fibre prepared, this fiber is made not only to have excellent flexibility, the performances such as warmth retention property, also has good mechanical property, heat resistance and COLOR FASTNESS, obtain long filament and the short fiber of different fiber number as required, this super imitative cotton technology of preparing is ripe, antistatic cationic dyeable polyester composition and method of making the same (CN103073710A) as a kind of in Chinese patent.This fibrid is compared with conventional polyester fiber, and the structure of fiber is more loose, and degree of crystallinity is lower, and the degree of orientation is lower, introduces many groups having more high forces with dyestuff simultaneously.Due to the change of the molecule segment and fibre structure that introduce other type, thus this fiber is the same with real silk, non-refractory, generally dyes by cation dyes, instead of adopts DISPERSE DYES.We are by a large amount of dye tests, find with conventional polyester unlike, contain sulfonic group in the fiber due to super imitative cotton, fraction DISPERSE DYES is not suitable for upper dye this kind of fiber, carries out with tinctorial, contaminates serious skew can occur for the coloured light of sample.As long as but in advance through screening, a part of DISPERSE DYES stands good in super imitative cotton dyeing, and keeps coloured light constant in wider pH value range.
Cocoon fiber has the performance of its uniqueness, due to the side chain on the large molecule of cocoon fiber and backbone molecule two ends contain freely acidic-group (as-COOH) and basic group (as-NH
2), protein molecule not only can have been ionized as acid but also as alkali, and therefore cocoon fiber possesses amphotericity.When isoelectric state (pH value is generally between 3.5 to 5.2), fiber is except presenting complete non-ionizing form, and mainly in molecule, carboxyl and amino dissociation simultaneously exist with the form accepting proton.REACTIVE DYES can go up dyeing silk fiber under faintly acid, neutrality or weak basic condition, and under mildly acidic conditions, REACTIVE DYES is combined with fiber mainly through hydrogen bond, Van der Waals force and ionic bond, and wet colour fastness is poor; In neutral conditions, dyestuff and fiber, except being combined by hydrogen bond and Van der Waals force, also have a small amount of covalent bonds; Under weak basic condition ,-OH ,-NH in dyestuff and cocoon fiber
2react, be combined mainly through covalent bond with cocoon fiber, wet fastness is fine.Because cocoon fiber alkali resistance is poor, therefore dye in the dye bath that pH value is higher during dyeing, when especially dyeing temperature is higher, usually can affect gloss and the feel of real silk.But when dyeing in acid bath, the REACTIVE DYES with anionic charge is easy to combine with ionic bond with cocoon fiber, this is the main cause that in acid bath, REACTIVE DYES has very high dyestuff dye-uptake.Still have covalent reaction that is amino and cocoon fiber in acid condition, but the amino content very low (0.2mol/kg) on cocoon fiber, therefore covalent bonds under acid condition is limited.And dye in alkaline bath, in the amino on cocoon fiber and hydroxyl oxygen anion and dye molecule, the nucleophilic displacement of fluorine (or addition) of active group is reacted, with covalent bonds.Adding of alkaline agent is conducive to cocoon fiber-NH
2existence and cocoon fiber-OH be ionized into negative oxygen ion, thus be conducive to dyestuff and fiber with covalent bonds, first high-temp dyeing in acid condition in the present invention, the dyeing then adding alkali fixation at a lower temperature 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 is more than 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, cloth cover is clean, and fiber rebound is good, and dyeing course is little to super imitative cotton and that real silk is powerful loss.
(3) be conducive to improving the dye-uptake of REACTIVE DYES in the dyeing of acidic high-temperature condition, DISPERSE DYES completes the diffusion of dyestuff, diffusion and fixation process, and dyestuff can go deep into fabric and fibrous inside, can by heavily fabric imbue; Add alkali fixation continuously at cryogenic conditions, because Dye Adsorption is on fiber, alkaline agent can be made more to be made full use of, obtain higher fixation efficiency, also can effectively alleviate DISPERSE DYES, real silk and super imitative cotton destruction or damage, cloth cover is more clean simultaneously.
(4) colouring method of super imitative cotton silk blend fabric provided by the invention, adopt the mode of co-bathing dyeing, do not need in dyeing course to use any carrier analog assistant, with short production cycle, energy resource consumption is low, and production cost is little.Meanwhile, the raising of dyestuff dye-uptake and degree of fixation, reduce residual liquid discharge concentration, loose colour reduces greatly, and the raising of COLOR FASTNESS alleviates intensity of soaping, and effectively reduces the total release of sewage, is conducive to environmental protection, can meets small lot batch manufacture, the requirement of multi items.
