Description

The method of one-bath dyeing

Technical field

The present invention relates to the colouring method of textiles, BLENDED FABRIC particularly cotton and other fibers material the method for one-bath dyeing.

Background technology

Textile printing and dyeing enterprises generally all adopts two-bath process to colouring method cotton or cotton and other fibers material BLENDED FABRIC (as polyamide fibre, ammonium synthetic fibre, nylon etc., except that acrylic) now.Its main technique step is as follows: will treat that 1, the dyeing and weaving thing carries out boiling-off, and remove oil, cured matter and other impurity.2, with REACTIVE DYES the cotton in the fabric is dyeed for the first time.3, to after the fabric fixation through first dyeing, clean.4, according to the difference of the fibers material of blending, select the dyestuff of heterogeneity (acidity, faintly acid, neutrality etc.), fabric is carried out the second time dye.5, soap the flush away loose colour after cleaning with clear water.In the two bath process production process, dye with temperature required higher dyestuff earlier, between first dyeing and the secondary dyeing two procedures fabric is cleaned, dye with temperature required lower dyestuff again, though the cleaning process in the middle of having utilized is to cooling off through the high temperature fabric that just dyes, but cause the waste of water resource, it is more also to exist operation simultaneously, and technical process is longer, and it is not enough to waste time and energy etc., and secondary dyeing causes painted inhomogeneous sometimes, easily causes defective product.

Summary of the invention

The objective of the invention is in order to solve existing deficiency in the above-mentioned prior art, and provide cotton and fibers material in a kind of BLENDED FABRIC in a dipping bath, to dye, with the method for the one-bath dyeing simplifying production process, enhance productivity.

The present invention is that the technical scheme of using that achieves the above object is: a kind of method of one-bath dyeing, according to waiting to dye in the BLENDED FABRIC fibers material and waiting to dye the different of color, select the dyestuff determined, with selected dyestuff and REACTIVE DYES mixed dissolution; Characteristic according to temperature required lower dyestuff in the mixed dye is adjusted dyeing condition, and add shortly dye, slow dye and the fixation material dyes, after reaction is finished, adjust dyeing condition according to temperature required higher dye characteristic in the mixed dye again, cool off after dyeing is finished, enter matting.

In the method for above-mentioned one-bath dyeing, satisfy the condition of temperature required lower dyestuff in the mixed dye earlier, otherwise the cooling required time is longer naturally after the pyroreaction, adds water for cooling and has then changed bath raio.The body lotion cooling of higher temperature is relatively more difficult.Under the reaction condition of lower temperature, add shortly dye, slow to dye material be glauber salt, also can be salt, the fixation material is strong base-weak acid salt (as sodium carbonate, tri-sodium phosphate etc.) or liquid caustic soda etc.REACTIVE DYES and selected acidity (faintly acid, neutrality etc.) dyestuff are mixed, be made into 35-70 ℃ solution, put into by bath raio 1: 15～20 and to treat the dyeing and weaving thing, be incubated 30～60 minutes after adding accelerant and color-fixing agent, adjust dye liquor PH to 5.5～7.5 then, be warming up to more than 95 ℃, be incubated 60～80 minutes; Naturally be cooled to below 80 ℃ and clean.

Since key feature of the present invention be in one bathes earlier with mixed dye in temperature required lower dye temperature condition heat, adjust dyeing condition according to temperature required higher dye characteristic in the mixed dye again, and related dye dosage in the dyeing course, as shortly dye, slow glauber salt, salt and the fixation material that dyes material all be the conventional knowledge of this specialty those of ordinary skill, so be not described in detail at this.

The invention has the beneficial effects as follows: it removes the cleaning refrigerating work procedure between twice staining reaction in the two bath process by making the reaction earlier of temperature required lower dyestuff, has shortened the production time, has improved production efficiency, has reduced production cost.It has also improved the utilization rate and the dyeing quality of dyestuff, and uniform coloring is firm, has reduced faulty materials, and simultaneously, it can also save great amount of water resources, reduces the sewage emissions amount, helps environmental protection.

The present invention is further elaborated in conjunction with the accompanying drawings below by embodiment, but following embodiment does not limit protection scope of the present invention.
