Embodiment 1

[0021] 80Kg Dekaisu Black B, 10Kg Dekaisu Orange PS and 10Kg Dekaisu Yellow PS three kinds of dyes are fully pulverized and then added to a 500L blending tank in turn, fully stirred for 2 hours, sampling inspection, after confirming that the mixture is uniform Packing, the hair black dye composition of about 100kg can be obtained.

[0022] Dye the wool with the aqueous solution of the black hair dye of Example 1, add acetic acid and stir during the dyeing, adjust the pH value to 4, heat up to 98°C, dye for 80 minutes, wash once with cold water, wash twice with hot water at 50°C, and wash once with cold water drying.

[0023] By above-mentioned dyeing process, obtain the fastness index of the dye composition of embodiment 1 as shown in table 1 below:

Abstract

The invention relates to a dye composition which comprises deksol black B, deksol orange PS and deksol yellow PS. Dyeing is carried out on protein fiber materials such as hair, wool and the like, according to a preferable dye process by adopting the dye of the invention, high dyeing rate, good level-dyeing property, bright chromatic light can be ensured, with pH adjusted by adding sulphuric acid, acetic acid and methanoic acid to a compound to be dyed, fastness properties are excellent, moreover, the dye meets environmental requirements.

Description

technical field [0001] The invention relates to an improved black dye composition suitable for dyeing protein fiber materials such as hair and wool, in particular to a black dye composition for dyeing protein fiber materials such as hair and wool and a dyeing method thereof. Background technique [0002] The dyeing of hair and related products is generally carried out by acid dyes, metal complex dyes or mordant dyes. [0003] Although acid dyes have a complete spectrum, bright colors and simple dyeing process, the wet fastness of dyeing is very poor because acid dye molecules and protein materials such as hair and wool are mainly bound by ionic bonds to cause dyeing. In addition to ionic bonds between metal complex dye molecules and protein materials such as hair and wool, there may also be hydrogen bonds, van der Waals forces, and coordination bonds. Therefore, the wet fastness of dyeing has improved, but due to the molecular weight of the dye Large, so the solubility and ...
