Problems solved by technology

[0002] The existing textile scouring process is: pretreatment → pickling → sodium chlorite bleaching → water washing → hydrogen peroxide bleaching → water washing, which mainly uses sodium chlorite to produce chlorination reaction with lignin under acidic conditions to remove lignin Although this method is very good for lignin removal and fiber bleaching, it also has many shortcomings: under the action of high-temperature strong alkali and high-concentration chlorine bleaching, the damage to fabric fibers is relatively large. The atmosphere and surface water system are particularly polluted, have carcinogenic and teratogenic effects on the human body, are highly corrosive, flammable and explosive, and the process is complex and consumes a lot of energy.

Embodiment 1

[0032] For the semi-bleached yarn of hemp boiled and bleached linen produced in rain and dew in Heilongjiang:

[0033] The entire cooking and bleaching process is divided into two steps: the first step is biological enzyme scouring, and the specific processes include: biological enzyme scouring, extraction / alkaline oxygen bleaching and urea peroxide bleaching, each process does not need to drain the residual liquid, directly or Lower the temperature to 60°C, add the chemicals required for the next process, and continue to perform the next process. The second step is the water washing process, which is mainly water washing with gradient cooling, so that various impurities dissolved in the solution can be fully washed.

[0034] First prepare the scouring solution according to the following ratio:

[0035] Polyphenol oxidase 0.03g / l;

[0036] Xylanase 0.006g / l;

[0037] Pectinase 0.2g / l;

[0038] Glucose 1.2g / l;

[0039] Sodium sulfite 1.114g / l;

[0040] EDTA 0.15g / l;

Embodiment 2

[0047] For Heilongjiang-produced rain and dew hemp boiled flax primary color yarn:

[0048] The entire cooking and bleaching process is divided into two steps: the first step is biological enzyme scouring, the specific process includes: biological enzyme scouring, extraction, each process does not need to drain the residual liquid, and directly adds the chemicals required for the next process, Continue to the next procedure. The second step is the water washing process, which is mainly water washing with gradient cooling, so that various impurities dissolved in the solution can be fully washed.

[0049] First prepare the scouring solution according to the following ratio:

[0050] Polyphenol oxidase 0.03g / l;

[0051] Xylanase 0.006g / l;

[0052] Pectinase 0.2g / l;

[0053] Glucose 1.2g / l;

[0054] Sodium sulfite 1.114g / l;

[0055] EDTA 0.15g / l;

[0056] Anthraquinone 0.5g / l;

[0057] Then put Yuluma into the above-mentioned scouring agent solution, the reaction condition...

Embodiment 3

[0060]Concrete process is the same as embodiment 1, but compound biological enzyme / mediator system changes to some extent:

[0061] Manganese peroxidase 0.1g / L;

[0062] Xylanase 0.001g / L;

[0063] Pectinase 0.5g / L;

[0064] Cellulose 3g / L;

[0065] DTPA 0.1g / L;

[0066] Hydrosulfite 0.1g / L;

[0067] Sodium anthraquinone sulfonate 3g / L;

[0068] 1-Hydroxybenzotriazole 3g / L;

[0069] Piricarol 0.1g / L;

[0070] Benzoic acid 0.1g / L;

[0071] Alkylphenol polyoxyethylene ether 1g / L.

Abstract

A composite biologic enzyme-medium system for the bucking technology of fabrics without environmental pollution is prepared from one or more of lignin oxidase, manganese oxidase and polyphenol oxidase, pectinase, xylanase, and medium system. Its application is also disclosed.

Description

technical field [0001] The invention belongs to the technical field of pretreatment in the textile industry, and in particular relates to a composite biological enzyme / mediator system used in a textile scouring process and its application. Background technique [0002] The existing textile scouring process is: pretreatment → pickling → sodium chlorite bleaching → water washing → hydrogen peroxide bleaching → water washing, which mainly uses sodium chlorite to produce chlorination reaction with lignin under acidic conditions to remove lignin Although this method is very good for lignin removal and fiber bleaching, it also has many shortcomings: under the action of high-temperature strong alkali and high-concentration chlorine bleaching, the damage to fabric fibers is relatively large. The atmosphere and surface water system are particularly seriously polluted, have carcinogenic and teratogenic effects on the human body, are highly corrosive, inflammable and explosive, and the...
