Embodiment 1

[0017]a, prepare a horseradish peroxidase catalytic dyed bath:

[0018]Yanphenol, 2,5-diaminophenylsulfonic acid, horseradish peroxidase, hydrogen peroxide were mixed with water, and stir evenly to obtain a horseradish peroxidase catalytic dyed bath. The ratio of phthalphenols, 2,5-diaminophenylbenzenesulfonic acid is 1: 3, and the horseradish peroxidase addition is 0.2 g / L, 27% hydrogen peroxide addition amount is 2 ml / L, adjust the pH. Take 5.

[0019]b, dyeing:

[0020]In the oscillation water bath of 50-70 r / min, a horseradish peroxidase catalyzed a toner to 45 ° C, and a cotton fabric that was wetted in advance was put into a horseradish peroxidase catalytic dyed bath for 2 h. The bath ratio is 1:15; use hot water cleaning, the temperature is 50 ° C, the time is 1:15; the bath ratio is 1:15; uses normal warm water, the time is 5 min, the bath ratio is 1:15; dry, the temperature is 80 ° C .

Abstract

The invention provides a horseradish peroxidase catalytic dyeing method for cotton fabric. The method comprises the following step that catechol, 2, 5-diaminobenzenesulfonic acid, horseradish peroxidase, hydrogen peroxide and water are mixed and stirred uniformly to obtain a horseradish peroxidase catalytic dyeing bath, wherein the ratio of the catechol to the 2, 5-diaminobenzenesulfonic acid is 1: 3 to 1: 10, the addition amount of the horseradish peroxidase is 0.1-0.5 g / L, the addition amount of the 27% hydrogen peroxide is 1-4 mL / L, and the pH value is adjusted to 4-6. According to the method, the technical problem of how to optimize the current dyeing process can be solved, the cotton fabric dyed by using the method is high in fixation rate and color fastness, the discharge of printing and dyeing wastewater can be effectively reduced, and the method is of great significance to green production of the textile printing and dyeing industry.

Description

Technical field[0001]The present invention belongs to the field of textile dyeing, and in particular, the present invention relates to a method of catalytic staining cotton fabric horseradish peroxidase.Background technique[0002]At present, in the printing and dyeing production process, the use of the active dye is stained with cotton fabrics, the active dye dyeing cotton fabric has the advantage of color, excellent in competitive dye, low dye, difficulty soap, dyed wastewater The color of chromaticity is also impossible to neglect. Mamage peroxidase referred to as HRP as a peroxidase extracted from a horseradish, a protein containing ferrite, a protein containing a ferrite, a molecular weight of a ferrite, a protein having a ferrous protein and brown iron porphyrin. 44kda, the catalytic effect is most obvious when pH is 5 or so, is an excellent "green catalyst", HRP has the advantages of strong catalytic activity, good environmental stability, and has a wide range of catalysts. It ...
