Embodiment 1

[0020] The enzyme preparation used for the one-bath method of polishing and dyeing with hydrogen peroxide, according to mass percentage, its composition is:

[0021] Catalase 10%

[0022] Cellulase 50%

[0023] Sorbitol 10%

[0024] Potassium Sorbate 0.3%

[0025] Deionized water makes up 100%

[0026] The preparation method is as follows:

[0027] (1) Weigh potassium sorbate, sorbitol and deionized water according to the above mass percentages;

[0028] (2) Dissolve potassium sorbate and sorbitol in deionized water to obtain a diluted solution;

[0029] (3) Adjust the pH of the diluted solution to 5.2 with acetic acid. Then add the weighed cellulase and catalase, stir evenly, and let stand to obtain the product.

Embodiment 2

[0031] The enzyme preparation used for the one-bath method of polishing and dyeing with hydrogen peroxide, according to mass percentage, its composition is:

[0032] Hydrogen peroxide 5%

[0033] Cellulase 30%

[0034] Sorbitol 10%

[0035] Potassium Sorbate 0.3%

[0036] Deionized water makes up 100%

[0037] The preparation method is as follows:

[0038] (1) Weigh potassium sorbate, sorbitol and deionized water according to the above mass percentages;

[0039] (2) Dissolve potassium sorbate and sorbitol in deionized water to obtain a diluted solution;

[0040] (3) Adjust the pH of the diluted solution to 5.0 with acetic acid. Then add the weighed cellulase and catalase, stir evenly and let stand to get the product

Embodiment 3

[0042] The application instructions of the enzyme preparation for the one-bath method of polishing and dyeing with hydrogen peroxide are as follows:

[0043] The process flow of the one-bath method for deoxidizing, polishing and dyeing is:

[0044] (1) Oxygen bleaching, (2) Deaerator polishing and dyeing one-bath treatment, (3) Finishing.

[0045] The above process flow will be further explained below.

[0046] (1) Oxygen bleaching: According to the conventional oxygen bleaching process, after completion, drain, feed water, add glacial acetic acid to adjust the pH to neutral;

[0047] (2) Deaeration, polishing and dyeing one-bath treatment: add deaeration, polishing and dyeing one-bath enzyme preparation (Example 1 of the present invention) product 0.5% to 1.0% (based on the total mass of the fabric to be processed), run for 30 minutes, add Dyestuffs and sodium sulfate (reactive dye accelerator), heat up to 60℃, keep for 30-60min, add soda ash (dye fixing agent), keep for 30-60min, dra...

Abstract

The invention discloses an enzyme preparation for a deoxidizing, polishing and dyeing one-bath method and application of the enzyme preparation, and belongs to the technical field of enzyme preparations. The enzyme preparation for the deoxidizing, polishing and dyeing one-bath method comprises the following components in percentage by mass: 5 to 10 percent of catalase, 30 to 50 percent of cellulase, 5 to 10 percent of sorbitol, 0.1 to 0.3 percent of potassium sorbate, and the balance of deionized water. The enzyme preparation for the deoxidizing, polishing and dyeing one-bath method can be applied to dyeing and finishing of cotton fabrics, and fulfills the aim of integrating three procedures of removing residual hydrogen peroxide, polishing and dyeing. Compared with the conventional enzyme preparation, the enzyme preparation for the deoxidizing, polishing and dyeing one-bath method has the advantages of shortening the processing time by over 90 minutes, obviously improving the production efficiency and fulfilling the aims of remarkably reducing water consumption, reducing energy consumption, reducing sewage discharge and reducing cost.

Description

Technical field [0001] The invention relates to an enzyme preparation for the one-bath method of deoxygenation, polishing and dyeing, and its application, in particular to an enzyme preparation for the one-bath method of removing residual hydrogen peroxide in the dyeing and finishing of cotton fabrics, belonging to enzyme preparation technology field. Background technique [0002] The traditional dyeing and finishing process of cotton fabrics includes oxygen bleaching, hot water washing and deoxidation, biological polishing, dyeing and finishing. The method of removing residual hydrogen peroxide is to wash with hot water, which has low efficiency and high energy consumption. [0003] In recent years, the technology of removing residual hydrogen peroxide by biological enzymes has been developed, and the processing flow has been improved to oxygen bleaching, biological enzyme removal of hydrogen peroxide, biological polishing, dyeing and finishing. Using biological enzymes to remov...
