Embodiment 1

[0015] 300kg of Lanersol Red CE and 700kg of Norwich Yellow S-3R two dyes are fully pulverized and then added to a 2000L volume blending tank, fully stirred for 2 hours, sampled for inspection, and packed after confirming that they are evenly stirred, that is About 1000 kg of brilliant red dye composition can be obtained.

Embodiment 2

[0023] Put 200kg of Lanersol Red CE and 700kg of Norwich Yellow S-3R two dyes and 100kg of sodium sulfate into a blending tank with a volume of 2000L after being fully pulverized, then fully stirred for 2 hours, and sampled for inspection to ensure that the stirring is even After packing, the dye composition of about 1000kg can be obtained.

Abstract

The invention relates to a dye composition and a dyeing method thereof. The dye composition comprises Lanasol red CE (Huntsman) and Novacron yellow S-3R (Huntsman). Preferably, the dye composition also comprises sodium sulfate. The weight ratio of Lanasol red CE to Novacron yellow S-3R to sodium sulfate is (10-30):(60-80):(5-15), especially preferably 20:70:10. The dye composition has the advantages of environmental protection, high degree of dyeing, favorable level-dyeing property, right color and excellent fastness, and can slightly damage hair, wool and other protein fiber materials; and the dyeing technique is simple and easy to implement.

Description

technical field [0001] The invention relates to an improved dye, which is suitable for dyeing protein fiber materials such as hair and wool, in particular to a dye composition and a dyeing method for dyeing protein fiber materials such as hair and wool. Background technique [0002] The dyeing of hair and related products is generally carried out with acid dyes, metal complex dyes or mordant dyes. The wet fastness of hair dyed with acid dyes is quite poor; dyeing with metal complex dyes will cause great damage to hair and other materials, the brightness of dyed hair is poor, and the molecular structure of dyes contains heavy metal ions; Hexavalent chromium ions need to be added in the process, which causes great pollution to the environment, and the dyeing process is also relatively complicated. The hand feeling and brightness of the dyed hair are poor. Contents of the invention [0003] In order to overcome the problems of poor wet fastness after dyeing protein fiber mat...
