Problems solved by technology

However, when the dye concentration in the raffinate is higher than 5g / L, the decolorization effect of laccase will be inhibited
Therefore, in actual production, since the concentration of the dyeing residue in the jigger vat is generally higher than 3g / L, and the concentration of the dye in the jigger continues to increase, the decolorization speed of laccase is lower than the speed at which the dye dissolves or is hydrolyzed into water, resulting in a residual liquid Low decolorization rate of medium dyes
In this case, the dye that has not been destroyed will be stained on the cloth surface, resulting in a decrease in the fastness of the finished fabric. Therefore, it is of no practical significance to use laccase alone to achieve energy saving and emission reduction and to improve the color fastness of the fabric.
Patent CN102899195A "A Composite Enzyme for Soaping and Its Application Method" improves the residual liquid decolorization effect of laccase through sodium citrate, persulfate and polyvinylpyrrolidone and laccase, but because it does not consider The concentration of dye in the raffinate is constantly increasing, and the decolorization ability of laccase is constantly decreasing, resulting in the phenomenon of dye back staining
Therefore, it will not effectively improve the color fastness of the fabric

Abstract

The invention discloses a composite laccase soaping agent and a cotton fabric finishing method using the same. The composite laccase soaping agent comprises, by mass, 80-95% of laccase, 1-5% of calcium chloride, 1-5% of cupric chloride, 2-10% of octadecyl dimethyl benzyl ammonium chloride and 1-5% of fatty alcohol-polyoxyethylene ether. The cotton fabric finishing method comprises the following steps of carrying out washing by warm water, carrying out soaping by a maleic-methyl acrylate copolymer having a concentration of 1.0-2.0g / L, carrying out washing by hot water, carrying out soaping by the composite laccase soaping agent having a concentration of 0.5-1.2g / L, and carrying out washing by cold water. The composite laccase soaping agent can substantially destroy a dye chromophoric group, improve raffinate clarity and prevent fabric re-pollution by the dye.

Description

technical field [0001] The invention belongs to the field of finishing aids for textiles, and relates to a composite laccase soaping agent and a finishing method on cotton fabrics. Background technique [0002] At present, most of the anti-staining soaping agent raw materials used for preparing reactive dyes are inorganic salts, polyacrylic acid, organic phosphates, high molecular polymers, and surfactants. This type of soaping agent needs Soaping many times can improve the color brightness and color fastness of the fabric. This type of soaping process is inefficient and consumes water and energy. In addition, the printing and dyeing wastewater containing a large amount of dyes needs to be treated to reduce COD in order to meet the discharge standards, so it puts a lot of pressure on the environment. Laccase is a kind of copper-containing polyphenol oxidase, and the only product after the reaction is water, which is an environmentally friendly enzyme in essence. Laccase c...
