Abstract
The invention discloses a one-bath one-step dyeing method for a cotton and nitrile blended fabric. According to the one-bath one-step dyeing method, dip dyeing is performed on the cotton and nitrile blended fabric by adopting a neutral fixation active dye and a cationic dye, wherein an active base of the neutral fixation active dye is a niacin s-triazine active base. A dyeing process comprises the following steps of: dissolving the cationic dye into water to prepare dyeing liquor, adding a sedimentation prevention agent into the cationic dyeing liquor, fully stirring, adding the neutral fixation active dye, adjusting the pH value by an acetic acid-sodium acetate buffering solution, and after heat preservation is finished, performing washing, soaping, secondary washing and drying. With the adoption of the one-bath one-step dyeing method, the neutral fixation active dye replaces the conventional active dye in the conventional process and serves as the dye for dyeing cotton fibers in the cotton and nitrile blended fabric, and one-bath one-step dyeing for the cotton and nitrile blended fabric is realized; the shortcomings of complicated working procedures, high energy consumption and high water resource consumption of the conventional two-bath two-step process adopting an active dye or the cationic dye are overcome; and a phenomenon that the firmness of a product dyed by a direct dye or cationic dye one-bath one-step method is low is avoided.
Description
Technical field
The invention belongs to the dyeing and finishing technique field, relate to the neutral fixation REACTIVE DYES of a kind of use and cation dyes and realize that cotton nitrile BLENDED FABRIC one bathes one-step method dyeing, especially can simplification of flowsheet, reduce production costs.
Background technology
The advantages such as cotton nitrile blending or intertexture are present very popular class weaving face fabrics, and it not only has the comfortable softness of cotton fiber, ventilative and hygroscopicity is good, wearability is good also have the advantage such as fluffy, warming of acrylic fiber.At present, cotton/nitrile BLENDED FABRIC is widely used in a plurality of fields that the textile industry such as is spun at by underwear, cold-proof underwear, sweater, family, and demand is very vigorous.
But Main Problems is that its production efficiency is low in the present dyeing and printing process process of cotton nitrile blending or intertexture, and technological process is longer, the energy and to dye material consumption large.Because cotton fiber is adapted at using under the alkali condition reactive dyeing, and acrylic fiber is adapted at using under the solutions of weak acidity cationic dyeing, and the alkali resistance of acrylic fiber is relatively poor, these characteristics have determined that cotton/nitrile fabric is difficult to carry out one with activity/cation dyes and bathes one-step method processing, can only adopt two one-bath two-step process production technologies.Also have factory to adopt direct/cation dyes that cotton/nitrile fabric is carried out one and bathe one-step method processing, but because the fastness of direct dyes is relatively poor, the fastness of product is difficult to reach requirement.Therefore, how to develop cotton/nitrile fabric one bath one-step method dyeing processing technique and be called current cotton/nitrile printing and dyeing manufacturer urgent problem.
Summary of the invention
The object of the invention is to be difficult to realize that for cellulose fibre and acrylic fibers blending or intertexture REACTIVE DYES/cation dyes one bathe the shortcoming of one-step method dyeing, provide a kind of REACTIVE DYES/cation dyes one to bathe the one-step method colouring method, this method utilizes neutral fixation REACTIVE DYES and cation dyes as cotton nitrile blended fabric dyeing dyestuff, prevent simultaneously the interaction of two kinds of dyestuffs with the adding antisettling agent in dye bath, it is complicated both to have solved REACTIVE DYES/cation dyes two one-bath two-step process technique processes, the shortcoming that the energy and water resources consumption are large has also avoided direct dyes/cation dyes one bath one-step method dyeing product fastness on the low side.The product color that makes is even, has good fastness to washing and fastness to rubbing.
The present invention adopts following technical scheme: a kind of cotton nitrile BLENDED FABRIC one is bathed the one-step method colouring method, adopt neutral fixation REACTIVE DYES and cation dyes that cotton nitrile BLENDED FABRIC is carried out exhaust dyeing, the active group of described neutral fixation REACTIVE DYES is nicotinic acid s-triazine active group, dye process is with the water-soluble dye liquor that is mixed with of cation dyes, adding antisettling agent fully stirs in the CATION dye liquor again, add again neutral fixation REACTIVE DYES, then regulating dye liquor pH value with NaAc_HAc buffer solution is 4～7, when dye liquor temperature is 40 ℃ fabric is dropped in the dye liquor, dye bath ratio is 1:5～100, then the programming rate with 0.5～2 ℃/min is warming up to 80 ℃, programming rate with 0.2～1 ℃/min is warming up to 95～100 ℃ again, and being incubated 30～100min, insulation finishes after washing, soap, washing, oven dry.
Described cation dyes concentration is 0.1～2 % o.m.f.
Described antisettling agent is by the anionic aromatic sulphonate and the nonionic polyoxyethylene ether surface active agent is composite forms, and concentration is 0.5～2 g/L.
Described REACTIVE DYES concentration is 0.1～10 % o.m.f.
Described dye bath ratio is preferably 1:10～60.
Described neutral fixation REACTIVE DYES is the yellow red NF-3B of NF-GR, Argazol of Argazol or the blue NF-BG of Argazol.
The invention has the beneficial effects as follows: the present invention adopts neutral fixation REACTIVE DYES to replace conventional REACTIVE DYES in the traditional handicraft as cotton fiber dyeing dyestuff in the cotton nitrile BLENDED FABRIC, has realized that cotton nitrile BLENDED FABRIC one bathes one-step method and dye.This method utilizes neutral fixation REACTIVE DYES and cation dyes as cotton nitrile blended fabric dyeing dyestuff, it is complicated both to have solved REACTIVE DYES/cation dyes two one-bath two-step process technique processes, the shortcoming that the energy and water resources consumption are large has also avoided direct dyes/cation dyes one bath one-step method dyeing product fastness on the low side; Technical scheme technique of the present invention is simple, convenient operation, without specific (special) requirements, utilizes normal dyeing equipment just can carry out large-scale production to equipment, has broad application prospects.
