Embodiment 1

[0031] The mixing tank is a DSH-20 double-helix asymmetric stainless steel mixing tank with a revolution speed of 1 revolution / minute and an autorotation speed of 65 revolutions / minute. It is stirred at room temperature and the total feeding amount is ≤1.8 tons. Taking the production of 1 ton of low-temperature bleaching enzyme preparation as an example, the production and processing process is as follows: Accurately weigh hydroquinone oxidase according to the production configuration sheet: 200 kg, 650 kg of organic acid (formic acid or acetic acid), filler (silicon dioxide ) 150 kg, the order of feeding is as follows: filling material, buffer acid, and finally oxidoreductase. Before feeding, make sure that the mixing tank is dry and that all raw materials are free from agglomeration and deliquescence. Start stirring after all the raw materials are thrown in. After stirring for 10 minutes, 5-10 kilograms are released from the bottom and put into the top of the tank, and then s...

Embodiment 2

[0042] A preparation method for low-temperature bleaching enzyme preparation for indigo denim decolorization, comprising the following steps:

[0043] (1) According to the following components and parts by weight: hydroquinone oxidase 100 with activity of 2000 units / g, organic acid (adipic acid) 400, silicon dioxide 1;

[0044](2) Put the filling material and buffer acid into the double helix asymmetric stainless steel mixing tank, and finally add the oxidoreductase. The working state of the double helix asymmetric stainless steel mixing tank is that the revolution speed is 1 revolution / minute, and the rotation speed is 65 revolutions / minute. minute mixing tank;

[0045] (3) Start stirring after all raw materials are put in. After stirring for 10 minutes, release 5 parts from the bottom and put them into the top of the tank. After stirring for another 6 minutes, put them into the tank while stirring.

[0046] The low-temperature bleaching enzyme preparation is used for the de...

Embodiment 3

[0050] A preparation method for low-temperature bleaching enzyme preparation for indigo denim decolorization, comprising the following steps:

[0051] (1) Ingredients according to the following components and parts by weight: hydroquinone oxidase 200 with activity of 2000 units / g, organic acid (isophthalic acid) 500, silicon dioxide 100;

[0052] (2) Put the filling material and buffer acid into the double helix asymmetric stainless steel mixing tank, and finally add the oxidoreductase. The working state of the double helix asymmetric stainless steel mixing tank is that the revolution speed is 1 revolution / minute, and the rotation speed is 65 revolutions / minute. minute mixing tank;

[0053] (3) Start stirring after all the raw materials are put in, and after stirring for 12 minutes, release 8 parts from the bottom and put them into the top of the tank, and stir for another 7 minutes, then put them into the tank while stirring.

Abstract

The invention relates to a low-temperature bleaching enzyme preparation for indigo denim discoloring as well as a preparation method and application of the low-temperature bleaching enzyme preparation. The low-temperature bleaching enzyme preparation comprises the following components in parts by weight: 100-300 parts of oxidation-reduction enzyme, 400-700 parts of buffer acid and 1-300 parts of stuffing. A using method of the low-temperature bleaching enzyme preparation for indigo denim discoloring comprises the following steps: heating water to 20-30 DEG C, adding 0.5-2g/L low-temperature bleaching enzyme preparation, and processing for 5-30 minutes. Compared with the prior art, the low-temperature bleaching enzyme preparation prepared by the preparation method disclosed by the invention can be used at a low temperature, so that the use amount of pumice stones and a chemical strong oxidant is reduced, and a worn-look effect is achieved. The low-temperature bleaching enzyme preparation has the advantages of remarkably saving energy and protecting environment, lowering the production cost, reducing pollution of chemicals to water, being safe, and the like, is biodegradable and pollution-free to environment.

Description

technical field [0001] The invention relates to an enzyme preparation, in particular to a low-temperature bleaching enzyme preparation for indigo denim decolorization and its preparation method and application, belonging to the field of biological products. Background technique [0002] Traditional denim clothing used to be the most suitable work clothes for manual labor because of its thicker cloth surface, darker color, wear resistance and durability. Due to the development of the times and changes in trends, more and more new denim fabrics appear, including polyester-cotton blends, Tencel / cotton blends, hemp / cotton blends, etc. The fabrics have also changed from the original 12S roving count to the current 40S. Fine yarn counts above. Denim clothing has also developed from the single blue in the past to the current clothing types with various styles such as blue, black, blue-black, and color. It is the most popular clothing in the international market at present. [000...
