Embodiment Construction

[0006] The indigo vat dyeing darkening agent of the present invention is a kind of high-performance industrial auxiliary agent mainly used for indigo vat dyeing of denim. A homogeneous aqueous solution containing certain active ingredients. It is mainly composed of dispersant, sodium polyacrylate, anionic surfactant, industrial salt, fatty alcohol ethoxylate and at least one rare earth sulfonate. Its various components and contents are respectively:

[0007] Dispersant 5% to 70%;

[0008] Sodium polyacrylate 1%~50%

[0009] Fatty alcohol ethoxylate 1%~50%

[0010] Anionic surfactant 0.2% to 80%;

[0011] Rare earth sulfonate 0.2%~30%;

[0012] Industrial salt 0.2%~30%

[0013] Pure water 10% to 90%.

[0014] Among them, the above-mentioned dispersant is one or more of dispersant N, dispersant NNO, dispersant MF or dispersant M series, and the fatty alcohol ethoxylate is one of C8-C18 fatty alcohol ethoxylate. Sodium polyacrylate is a sodium polyacrylate solution or sol...

Abstract

The invention discloses an indigo reduction staining deep dyeing promoter which is a high performance deep dyeing promoter for denim indigo dyeing reduction. The invention is prepared mainly by dispersant, sodium polyacrylate, anionic surfactant, industrial salt, at least one kind of C8-C18 fatty alcohol ethoxylate and at least one kind of rare earth sulfonate. When the deep dyeing promoter is used for indigo dyeing reduction for denim, depth and fastness of the dyeing denim are obviously improved, degree of dyeing is further improved, and using amount of toxic dye indigo and dyeing period are reduced.

Description

1. Technical field [0001] The invention belongs to the technical field of denim dyeing and finishing. 2. Background technology [0002] At present, the high-performance darkening agents used in indigo vat dyeing of denim in China are mainly imported products from Europe, America and other regions, which are expensive. Domestic printing and dyeing auxiliaries enterprises have not been able to produce and provide such products. 3. Contents of the invention [0003] The purpose of the present invention is to provide a high-performance indigo vat dyeing darkening agent, to overcome the defects that domestic printing and dyeing auxiliaries enterprises fail to produce such products. [0004] The object of the present invention is achieved like this: the indigo vat dyeing deepening agent of the present invention is mainly made of dispersant, sodium polyacrylate, anionic surfactant, industrial salt, at least one C8~C18 fatty alcohol ethoxylate compound and at least one Compounde...
