Abstract

The invention discloses a technical method for dyeing white bristles into black bristles; and the production steps are as follows: selecting ordinary white bristles to put into a high-pressure reaction kettle, putting amino black 10B dyestuff, sodium bisulfate, ammonia and water into the high-pressure reaction kettle, pressurizing for boiling for 1 to 2 hours; adding the water, cooling the reaction kettle temperature to 50 to 70 DEG C, putting into acid black ATT-M dye, sodium bisulfate, pressurizing for boiling for0.5 to 1.5 hours; taking bristles in the reaction kettle out, and drying to obtain the black bristles. The technical method for dyeing the white bristles into the black bristles has the advantages of simple production process and low equipment requirements, process raw materials can be obtained from the market, the cost is low; the black bristles produced by the method are stable in quality, and comparative in chroma and brightness with that of natural black bristles, and may not fade by washing, soaping and pickling.

Description

A kind of white hair on the neck is dyed the process of black hair on the neck

Technical field

The present invention relates to a kind of process of white hair on the neck being dyed to black hair on the neck.

Background technology

In dataller's industry processed, bristles are main raw materials, and black hair on the neck is a kind of of main raw material, but natural black hair on the neck output is few, cannot meet the demand of dataller's industry processed, have limited system brush industrial expansion.

Summary of the invention

For overcoming above-mentioned deficiency, meet the demand of dataller's industry processed, the object of this invention is to provide and a kind ofly common white hair on the neck can be dyed to the process of black hair on the neck.

The solution of the present invention is as follows: a kind of white hair on the neck is dyed the process of black hair on the neck, and its production stage is as follows:

A, select common white bristles to put into autoclave, put into amino black 10B dyestuff, niter cake, ammoniacal liquor, water simultaneously in autoclave, pressurization is boiled 1～2 hour;

B, add water, reactor temperature is dropped to after 50～70 ℃, put into acid black ATT-M dyestuff, niter cake, pressurization is boiled 0.5～1.5 hour;

C, hairpencil in reactor is taken out, dry.

Each raw material weight percentage in described steps A is amino black 10B dyestuff 0.15%～0.3%, niter cake 0.15%～0.25%, ammoniacal liquor 0.15%～0.3%, water 90%～93%, white bristles 7%～8%.

Further, each raw material optimum weight percentage in described steps A is amino black 10B dyestuff 0.23%, niter cake 0.23%, ammoniacal liquor 0.2%, water 91.34%, white bristles 7.5%.

Further, ammoniacal liquor is that the water of 10% ammonia proportioning 90% makes.

Each raw material weight percentage in step B is acid black ATT-MI dyestuff 1%～2%, niter cake 1%～2%, water 96%～98%.

Further, each raw material weight percentage in described step B is acid black ATT-MI dyestuff 1.5%, niter cake 1.5%, water 97%.

Pressure when steps A is boiled with rapid B mesohigh reactor is 0.4～0.6L/CM ², temperature is 100～120 ℃.

Pressure when further, steps A is boiled with rapid B mesohigh reactor is 0.5L/CM ², temperature is 110 ℃.

Beneficial effect of the present invention:

1, manufacturing process of the present invention is simple, and equipment requirement is low, and the raw material in technique all can obtain from market, and cost is low;

2, the black hair on the neck steady quality that the present invention produces, colourity and brightness are suitable with natural black hair on the neck, and wash, soap, pickling is all colour-fast.

The specific embodiment

Embodiment 1
