Abstract

The invention discloses a one-bath dyeing method for a wool and polyacrylic fiber blend. The method comprises the steps of putting the wool and polyacrylic fiber blend into a jar, adding a leveling agent, sulfuric acid and an active dye for wool at 20-40 DEG C, heating to 70-80 DEG C at the speed of 0.5-1 DEG C per minute, preserving heat for 10 minutes, adding a cationic dye (acetic acid pulp), preserving heat for 10 minutes, heating to 98 DEG C at the speed of 0.3-0.5 DEG C per minute, preserving heat for 30-60 minutes, cooling to 50 DEG C, and discharging the blend from the jar. The method solves the problems of poor rubbing fastness, poor washing fastness, dark color, poor handfeel and the like which easily appear in traditional dyeing of the wool and polyacrylic fiber blend.

Description

Hair nitrile blending one-bath process method

Technical field

The invention belongs to colouring method, be specifically related to a kind of hair nitrile blending one-bath process method.

Background technology

The conventional coloring method of hair nitrile blended product carries out boiling under dye condition; but dye of boiling easily causes Wool Fibre Damage and dyeing defect, such as wool weightlessness, mechanical performance deterioration, rear road processing difficulties, feel are coarse, fabric yellowing, to contaminate light coloured light bright-coloured etc.; This technique carries out high temperature long time treatment to acrylic fiber, not only damages fiber, and energy consumption is high, too fast in order to prevent from cation dyes contaminate, and needs to add a large amount of retarding agents, but affects fiber tinctorial yield.Therefore, the low temperature dyeing technology studying hair nitrile blended product is necessary.At present, Some Enterprises is produced at trial application low temperature dyeing technique for wool, but there is the problem that dye is irregular, dye is not saturating and dyefastness is low.

Summary of the invention

In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of hair nitrile blending one-bath process method is provided, easy to operate, even dyeing.

Hair nitrile blending one-bath process method provided by the invention, hair nitrile blend is put into cylinder, 20-40 DEG C adds levelling agent, sulfuric acid, cotton reactive dye, with the ramp of 0.5-1 per minute DEG C to 70-80 DEG C, be incubated 10 points, add cation dyes (acetic acid making beating) insulation 10 points, then with the ramp to 98 DEG C of 0.3-0.5 per minute DEG C, insulation 30-60 divides, and is cooled to 50 DEG C and goes out cylinder.When cation dyes are selected, the dark blue RL of cationic yellow 7GL, Cationic Red 2GL, CATION that adopts does three primary colors, and light color adopts X-type cation dyes.The cotton reactive dye of 60 DEG C of dyeing that cotton reactive dye is commonly used is all passable, uses red 3BS, yellow 3RS, blue 2GLN, black N, KN-B better effects if.

Hair nitrile blending one-bath process method provided by the invention, its beneficial effect is, cotton reactive dye is applied to the dyeing of wool, because cotton is general lower by dyestuff price, on wool after dyeing, there is good dyefastness, be equivalent to the Color of medium-to-high grade hair dyestuff.Not only increase product quality, and, reduce dyeing cost, saved the time and used water.Solve the problems such as the crock fastness that traditional hair nitrile blend dyeing easily occurs is poor, washing fastness is poor, color and luster is not bright-coloured, feel is bad simultaneously.

Detailed description of the invention

Below in conjunction with an embodiment, hair nitrile blending one-bath process method provided by the invention is described in detail.

Embodiment

Hair nitrile blend is put into cylinder, 20-40 DEG C adds levelling agent, sulfuric acid, cotton reactive dye, with the ramp of 0.5-1 per minute DEG C to 70-80 DEG C, be incubated 10 points, add cation dyes (acetic acid making beating) insulation 10 points, again with the ramp to 98 DEG C of 0.3-0.5 per minute DEG C, insulation 30-60 divides, and is cooled to 50 DEG C and goes out cylinder.

Claims
