Problems solved by technology

The leveling agent of this invention can make wool and real silk evenly colored during dyeing, so that it has good level dyeing property and can also improve the dyeing rate of dye; Add urea to adjust the pH value, but as a protein, wool is acid-resistant and not alkali-resistant, and the addition of urea to the damage to wool quality has not been well suppressed

Abstract

The invention discloses a neutral leveling agent for dyeing wool fiber with an acid dye, and belongs to the field of dyeing auxiliary application. The neutral leveling agent is prepared from, by weight, 0.01-0.02 part of chrysophanol, 0.1-0.5 part of 2-methyl naphthalene, 12-13 parts of fatty amine polyoxyethylene ether, 14-16 parts of hydroxybiphenyl sodium salt and 160-200 parts of water. By means of the neutral leveling agent, the damage to wool fiber protein can be effectively reduced, and the quality of wool fabric is improved; meanwhile, good dyeing dispersity is achieved, wool fiber can be uniformly dyed with the acid dye, use is convenient, and high market popularization value is achieved.

Description

Technical field: [0001] The invention belongs to the application field of dyeing assistants, and relates to a neutral leveling agent for printing and dyeing wool fibers with acid dyes. Background technique: [0002] The main component of wool is keratin, which is composed of a variety of α-amino acid residues. The latter can be linked into spiral-shaped long-chain molecules, which contain carboxyl, amine and hydroxyl groups, which form salt bonds and Hydrogen bonds, etc. The long chains are connected by cross bonds formed by disulfide bonds of cystine. The above chemical structure determines the characteristics of wool. For example, when the long chain of wool fiber macromolecules is stretched by external force, it transitions from α-type spiral shape to β-type stretched type, and then returns to α-type after the external force is relieved. The appearance of wool is characterized by excellent elongation and elasticity of wool. The strong moisture absorption capacity of wool is...
