Embodiment 1

[0023] 15 parts by weight of laccase, 30 parts by weight of potassium persulfate, 20 parts by weight of soda ash, 15 parts by weight of polyvinylpyrrolidone with an average molecular weight of 50,000, 15 parts by weight of sodium polyacrylate with an average molecular weight of 3000, and 5 parts by weight of sodium polyacrylate with a viscosity of 200 centimeters The sodium carboxymethyl cellulose of poin is added into the mixer in sequence and stirred until it is evenly mixed to obtain a new type of low-temperature soaping agent.

[0024] Use a new type of low-temperature soaping agent to soap the cheese. Compared with the traditional soaping process, the number of soaping times is reduced from two times to one time, the single soaping time is shortened from 20 minutes to 15 minutes, and the soaping temperature is also reduced from 98°C to 60°C, which reduces the cost of soaping process Energy and water consumption make the soaping process more energy-saving, and at the same ...

Embodiment 2

[0026] 25 parts by weight of laccase, 25 parts by weight of sodium persulfate, 15 parts by weight of soda ash, 15 parts by weight of polyvinylpyrrolidone with an average molecular weight of 400,000, 15 parts by weight of sodium polyacrylate with an average molecular weight of 5000 and 5 parts by weight of polyvinylpyrrolidone with a viscosity of 400 Sodium carboxymethyl cellulose is added into the mixer in sequence and stirred until it is evenly mixed to obtain a new type of low-temperature soaping agent.

[0027] Use a new type of low-temperature soaping agent to soap the cheese. Compared with the traditional soaping process, the number of soaping times is reduced from two times to one time, the single soaping time is shortened from 20 minutes to 12 minutes, and the soaping temperature is also reduced from 98°C to 70°C, which reduces the cost of soaping process Energy and water consumption make the soaping process more energy-saving, and at the same time reduce process time, ...

Embodiment 3

[0029] 20 parts by weight of laccase, 70 parts by weight of ammonium persulfate, 30 parts by weight of caustic soda, 30 parts by weight of polyvinylpyrrolidone with an average molecular weight of 1,000,000, 30 parts by weight of sodium polyacrylate with an average molecular weight of 8000 and 20 parts by weight of sodium polyacrylate with a viscosity of 2000 centimeters The sodium carboxymethyl cellulose of poin is added into the mixer in sequence and stirred until it is evenly mixed to obtain a new type of low-temperature soaping agent.

[0030] Use a new type of low-temperature soaping agent to soap the cheese. Compared with the traditional soaping process, the number of soaping times is reduced from two times to one time, the single soaping time is shortened from 20 minutes to 14 minutes, and the soaping temperature is also reduced from 98°C to 65°C, which reduces the cost of soaping process Energy and water consumption make the soaping process more energy-saving, and at th...

Abstract

The invention discloses a novel cryogenic soaping agent. The novel cryogenic soaping agent is characterized by comprising the following components in percentage by weight: 5-25% of laccase, 25-45% of persulfate, 15-35% of alkali, 15-25% of polyvinylpyrrolidone, 15-25% of sodium polyacrylate and 5-10% of sodium carboxymethyl cellulose. The novel cryogenic soaping agent is applied to a soaping process after reactive dyeing, and can effectively remove a flooding color, a paste material and an auxiliary agent on fabric at a relatively low temperature to improve the color brilliance, color fastness and cleanliness of the fabric.

Description

technical field [0001] The invention relates to a novel low-temperature soaping agent and a preparation method thereof. Background technique [0002] Because reactive dyes have the advantages of complete color spectrum, easy color matching, bright color, low price, simple process, and good fastness, reactive dyes are widely used in the printing and dyeing of cellulose and other fibers. During the dyeing process, there are many unfixed dyes, hydrolyzed dyes, auxiliaries and other impurities in the dyeing solution or on the fabric, which must be soaped with multiple soaping agents to remove these impurities. , to improve the color brightness, color fastness and cleanliness of the fabric, so as to meet the product requirements. Such as figure 1 As shown, it is a schematic diagram of the soaping process of using traditional soaping agents to treat fabrics. Soaping twice at a high temperature of 98°C, the single soaping time is 20 minutes, the energy consumption and water consu...
