Problems solved by technology

[0002] Wool fabric is a kind of natural fiber fabric. Wool fiber has excellent performance, excellent curl and elasticity, warm and comfortable, and is loved by consumers. However, wool fabric has insufficient bright colors, poor wet fastness and felting shrinkage. The biggest problem, this is because the wool surface has a tight scale layer, and the outermost layer of wool scales contains a very thin hydrophobic layer, which affects the wettability of the wool surface and hinders the adsorption and diffusion of dyes, thus affecting the dye. In addition, its fiber characteristics are easy to feel and shrink, which also brings difficulties to uniform dyeing. In addition, some mordant dyes have environmental pollution when dyeing wool fabrics, and cannot adapt to the development of the environment of energy saving and emission reduction. Trends, how to improve the dyeing performance of wool, increase wet fastness, reduce environmental pollution, a dyeing composition suitable for wool fabrics that can solve the above problems is worth studying

Abstract

The invention discloses a wool fabric dyeing composition and an application thereof. The composition is composed of a dye A and a dye B. The dye A is a disperse dye composition applied in primary dyeing. The dye A is specifically applied in a supercritical carbon dioxide disperse dyeing process and the dyeing composition. The dye B is an acidic dye composition used in a secondary dyeing process. The dyeing composition used in the dyeing process twice is applied in different stages, and has stable chemical properties. With the dyeing composition, adhesion during wool fiber fabric dyeing is effectively enhanced, the occurrence probability of a felting phenomenon is reduced, and a color fixing effect is enhanced. With the dyeing composition, fabric dyeing color is bright, and fading is prevented. Dry and wet color friction is enhanced, the dyeing effect is good, dyeing is uniform, and fading is prevented.
