Abstract
The invention, belonging to printing and dyeing area for silk cloth, relates to a dyestuff alkali-washing dyeing method for polyester mixed textile dispersedly and directly. Said method is that under the condition of 7<PH<9 alkali, direct and dispersal dye of alkali resistivity are use as dyeing for polyester textile. Under the lower alkali condition, polyester fibre after dyeing can avoid shortcoming of a mass of flaw generated by lixiviation of slurry, oils and other catabolite in acidic bath. It can conquer damnification of dyeing and fibre under the circumstance of high temperature, pressure and alkali. The invention can conserve energy, decrease cost and improve production efficiency.
Description
Technical field
The invention belongs to technical field of textile printing, relate to a kind of polyester fiber cospinning textile used dispersion and direct dyes alkali bath dyeing method.
Background technology
Two-bath process is mainly adopted in the dyeing of polyester cotton at present, because the dyeability difference of fiber, will be with two kinds of dissimilar dyestuffs respectively to two kinds of stock-dyes, the composition of terylene need use disperse dyeing in the fabric, cotton composition needs direct dyeing, usually DISPERSE DYES dyes under acid condition, and direct dyes are to dye under neutrallty condition, therefore polyester cotton needs twice dyeing, promptly needs two baths to dye, and whole dye process is long, operation is many, waste energy, secondary dyeing simultaneously easily causes dyeing inhomogeneous, and production cost is higher, influences economic benefit of enterprises.
Summary of the invention
The purpose of this invention is to provide under a kind of weak basic condition, technology is simple, the polyester fiber cospinning textile used dispersion and the direct dyes alkali bath dyeing method of even dyeing.
The present invention realizes above-mentioned purpose by the following technical solutions: polyester fiber cospinning textile used dispersion and direct dyes alkali bath dyeing method, under the alkali condition of 7＜pH＜9, use non-reaction direct dyes of alkali resistance and alkali resistance disperse dye, to the polyester-cotton fabric one-bath process.
In dyeing water, add alkaline stabiliser, accelerant earlier, add dyestuff again.
Polyester-cotton fabric is put into the dyeing water, add alkaline stabiliser, accelerant, heat to 50～60 ℃, non-reaction direct dyes and DISPERSE DYES dissolving or dispersion back add in the dyeing water, 50～60min is warming up to 115～125 ℃, keeps temperature 30～50min, and 20～30min is cooled to below 80 ℃ and discharges raffinate, water is soaped, and goes out the cloth oven dry.
Alkaline stabiliser is made up of organic amine and anion surfactant or non-ionic surface active agent, and accelerant is water-soluble neutral salt, and wherein the addition of alkaline stabiliser is that every liter of dye liquor adds 3～5g, and the addition of accelerant is that every liter of dye liquor adds 5～15g.
The non-reaction DISPERSE DYES of alkali resistance is selected for use at least and is disperseed tangerine E-GFL, disperse scarlet S-3GFL, dispersed ruby S-2GFL, Disperse Red 3B, disperse bright blue S-GL, disperse blue H-3R, Disperse Blue 2BLN, disperse brilliant blue E-4R, disperse brown H-2RL, disperse dark brown S-2BL, disperse brown S-2RL, disperse grey D, disperse black EX, Dianix Red AC-E, Dianix Yellow AC-E, a kind of among the Dianix Blue AC-E, alkali-proof direct dyes are selected for use at least and are directly frozen yellow G, direct fast yellow 7GFF, direct scarlet 4BS, direct pink 12B, direct acid blue 5B, direct copper blue 2R, direct blue 2B, direct dark green NB, direct dark brown MM, direct grey D, directly D-RSN is deceived in blending, direct blended spinning navy D-R, the blue D-RGL of direct blending, direct blended carbuncle D-BLL, direct a kind of in the blending brown D-RS.
Also added buffer before adding dyestuff, buffer is an ammonium salt.
Organic amine: buffer: surfactant is 1～3: 1～3: 1.
Textile dyeing is finished to be cooled to below 80 ℃ and is discharged raffinate, at 60～80 ℃ of following hot water wash 5～10min, and the 5～10min that under 80～90 ℃, soaps, again at 60～80 ℃ of following hot water wash 5～10min, cold wash 5～10min under the last room temperature goes out the cloth oven dry.
The present invention is one-bath process under the alkali condition of 7＜pH＜9, weakly alkaline environment has improved the dissolubility of non-reaction direct dyes, one-bath process can overcome slurry, finish and other catabolite that terylene cleans owing to pre-treatment and separates out in acid bath and produce many shortcomings of dying defect under the weak basic condition, also overcome of the damage of the alkaline environment of High Temperature High Pressure to dyestuff and fiber, the present invention has saved the energy, reduce production cost, improved labor productivity; Dyeing can also make fabric smooth under the alkali condition, plays even dyeing effect, improves the quality of products effectively; By auxiliary agent good stability, the good water solubility that organic amine, buffer, surfactant are formed, nontoxic and can play the level dyeing effect, cheap; The organic amine stabilizing agent adds in the dye liquor, has the effect of regulating the pH value, dye liquor pH value can be transferred to 7＜pH＜9, and it and buffer cooperation have buffer capacity, keep the alkalescent of dye liquor, and the organic amine stabilizing agent also has the resistance to reduction energy, helps the stable of dyestuff; The effect that surfactant played is the uniformity that improves dyeing, makes after the textile dyeing bright-colored; Neutral salt plays the short effect of dying, and improves the dye-uptake of dyestuff; Non-reaction direct dyes price is low, easy to use, need not to resemble strict control staining reaction process conditions the REACTIVE DYES, has simplified dyeing.
