Abstract
The invention relates to a one-bath one-step dyeing method for a dralon/cotton blended fabric. The method comprises the following steps: impregnating and dyeing the dralon/cotton blended fabric by adopting a neutral bath fixation reactive dye and a disperse type cationic dye; putting the dralon/cotton blended fabric into a solution with a surfactant for pre-treatment; then, soaking in a bleaching agent solution for bleaching treatment; then, dissolving the reactive dye and the cationic dye with warm water at 40 DEG C to prepare a dye liquid; fully stirring, adjusting the pH value to 4-8.5 by using a buffer liquid; putting the fabric into the dye liquid; controlling the dye bath ratio at 1: 10 to 1: 100; then, controlling temperature rise and insulation for 10-90 minutes; and then washing, soaping and drying. Compared with the prior art, the method can be used for solving the problem that the reactive dye and the cationic dye cannot be in a same bath as negative and positive charges of the reactive dye and the cationic dye react and also solving the problem of dyeing condition difference between the reactive dye and the cationic dye.
Description
Technical field
The invention belongs to dyeing and finishing technique field, especially relate to a kind of moral suede/cotton blended fabric one and bathe an one-step dyeing method.
Background technology
Acrylic fibers have cruel woolly characteristic, again due to the reinforcement that people realize animal protection, this performance be other synthetic fiber incomparable, the application thus establishing acrylic fibers has advantageous advantage.In recent years, along with the development of economy, the requirement of people to weaving face fabric is also more and more higher, and traditional acrylic fiber can not meet the demand of consumers in general, grows with each passing day for the demand of the acrylic fibers fibre in differentiation with more excellent properties in domestic market.Recently, Germany's research and development and the Dralon thin dawn special-shaped acrylic fiber released, this fiber is spinned by acrylic fibers dry spinning technology, smooth surface, cross section is dumb-bell shape, Dralon fiber has ultra-fine and feature that is abnormal shape concurrently, which dictates that Dralon fiber has more characteristic compared with common acrylic fiber.
Moral Down Fiber is soft, fluffy plentiful, warmth retention property is good, exactly likes wool, moisture permeability is also better than common acrylic fiber, but still not as good as natural fabric, therefore, by natural fiber mixed fabrics that is spun into such as moral Down Fiber and cottons, it not only has the comfortable softness of cotton fiber, the advantages such as the advantages such as ventilative and hygroscopicity is good, also have acrylic fibers fluffy, warming.At present, many companies are just actively devoted to moral Down Fiber and are correlated with the Application and Development of fabric, and moral suede/cotton blended spinning face fabric also will be widely used in cold-proof underwear, sweater, shirt, cowboy, and multiple field such as to be spun at by family, has good market prospects.Moral suede/cotton blended fabric is made various wearing fabric, needs that dyeing is carried out to it and arrange.
The stock-dye of different component needs to adopt different classes of dyestuff usually, and dyeing also adopts two one bath two-step methods, one bath two stage process and one-bath one-step dyeing usually.For moral suede/cotton blended fabric, cellulose dyeing is conventional directly, actively waits dyestuff, acrylic fiber generally uses cationic dyeing, also useful disperse dyeing under individual cases.It is first contaminate moral suedes by cation dyes in 100 DEG C that one-bath two-step process dyes, and is cooled to 80 ~ 90 DEG C and adds direct dyes dye cotton again after treating the dyeing of moral suede.Two bath process, first with cation dyes dye moral suede, after reduction cleaning, then with other dyestuff resisdye cotton fiber.Some factory adopts directly/CATION to carry out one-bath one-step dyeing dyeing to blended yarn woven fabric, shorten dyeing time to a great extent, reduce energy consumption, but the fastness of direct dyes is poor, is difficult to reach requirement.Therefore in order to improve dyefastness, general employing Dyeing of Cotton Fabric with Reactive Dyes fiber, and cotton fiber is applicable to using reactive dyeing in the basic conditions, in REACTIVE DYES dye and color fixing temperature (60 ~ 80 DEG C) lower, high temperature can make dyestuff be hydrolyzed acceleration, even reduced, hydrolysis destroys, and affects dyeability; Moral Down Fiber to be adapted under mild acid conditions, with cation dyes (100 DEG C) dyeing at relatively high temperatures, though the alkali resistance of moral Down Fiber is better than common acrylic fiber, the wearability of fiber still being made under high-temperature alkaline condition to reduce.In addition, cation dyes are with cation group, and REACTIVE DYES is then with negative charge, and both can produce dye precipitated because anions and canons reacts with during bath, cannot carry out upper dye.These factors determine moral suede/cotton and are difficult to realize CATION/REACTIVE DYES one-bath one-step dyeing dyeing.
The people such as Miao Shujun adopt Dyeing with Disperse/Reactive to carry out one-bath one-step dyeing dyeing to nitrile/cotton mixture fabric, improve dyefastness, but the affinity of DISPERSE DYES to acrylic fiber is lower, saturation value is little, institute can only be applicable to light color in dye in this approach, and the utilization rate of dyestuff is very low, and dyeing cost is high, dyeing waste-water discharge capacity is large, still needs to dye by cation dyes for dark and color and luster bright-coloured individually.
Chinese patent CN102936859A discloses cotton/nitrile BLENDED FABRIC one-bath one-step dyeing colouring method, neutral fixation REACTIVE DYES and cation dyes are adopted to carry out exhaust dyeing to cotton/nitrile BLENDED FABRIC, the active group of described neutral fixation REACTIVE DYES is nicotinic acid s-triazine active group, dye process is by water-soluble for the cation dyes dye liquor that is mixed with, add antisettling agent more fully to stir in CATION dye liquor, add neutral fixation REACTIVE DYES again, then regulate dye liquor pH value with NaAc_HAc buffer solution, insulation terminates after washing, soaps, washes, dries.The antisettling agent adopted due to this patent is formed by anionic aromatic sulphonate and nonionic polyoxyethylene ether surfactant compound, alleviate the combination of the REACTIVE DYES of cation dyes and anion and the precipitation produced by anionic aromatic sulphonate and the combination of cation dyes and the peptizaiton of nonionic polyoxyethylene ether surfactant, but more than dyeing temperature is higher than the cloud point of nonionic surface active agent, peptizaiton reduces, and the precipitation of dyestuff still can occur; In addition, in dye bath antisettling agent add the coloured light that membership affects DYED FABRICS, and reduce the dye-uptake of dyestuff.
To sum up, in order to energy Simplified flowsheet, reduce energy consumption, can reach textile dyeing requirement again, exploitation moral suede/cotton blended fabric CATION/REACTIVE DYES one-bath one-step dyeing dyeing processing technique is current many manufacturers urgent problems.
Summary of the invention
Object of the present invention is exactly provide the difficult point of a kind of activity/cation dyes to existing during the dyeing of moral suede/cotton blended fabric one-bath one-step dyeing to overcome defect that above-mentioned prior art exists, there is provided a kind of technique simple, the one-bath one-step dyeing dyeing of every fastness well environmental protection again, the method utilizes neutral fixation REACTIVE DYES and disperse type cationic dye as moral suede/cotton blended fabric dyeing dyestuff, selected dyestuff had both solved REACTIVE DYES and cation dyes negative and positive charge reaction and had produced precipitation and cannot with the problem of bath, also REACTIVE DYES and cationic dyeing condition difference sex chromosome mosaicism is solved.Product color after Colour Difference is even, has good color fastness to washing and fastness to rubbing.
Object of the present invention can be achieved through the following technical solutions:
