Problems solved by technology

[0004] In short, the current products on the market that have the effect of removing mold stains on clothes are mainly bleaching products. High dosage of bleaching agent has a good effect, but it is mainly aimed at pure white clothes, and it will cause great damage to fabrics and human health, and is not gentle and environmentally friendly.
Products that can have the effect of color bleaching are either not ideal in effect, not environmentally friendly or expensive

Embodiment 1

[0023] The liquid detergent of this embodiment is made up of following components: deep eutectic solvent (mol ratio is 1:1:1 lactic acid: choline chloride: urea mixture; mass fraction 20%), hydrogen peroxide (mass fraction 15%) %), 0.1 g / mL sodium hydroxide aqueous solution (mass fraction 30%), water (mass fraction 35%), pH 7.0.

[0024] Operation process:

[0025] Take 10mL of the obtained liquid detergent and put it into a small beaker, immerse the moldy cloth (chemical fiber, cotton cloth, colored cotton cloth) in the liquid detergent in the beaker, let it stand at room temperature for 2 hours, then wash it with clean water 3 to 5 times, and let it dry in the air. Mildew stains on the fabric can be removed after drying.

Embodiment 2

[0027] The liquid detergent obtained in this example is composed of the following components: deep eutectic solvent (a mixture of lactic acid and urea with a molar ratio of 1:1; the mass fraction is 20%), hydrogen peroxide (15% by mass), 0.1 g / mL sodium hydroxide aqueous solution (mass fraction 30%), water (mass fraction 35%), pH 7.0.

[0028] Operation process:

[0029] Take 10mL of the obtained liquid detergent and put it into a small beaker, immerse the moldy cloth (chemical fiber, cotton cloth, colored cotton cloth) in the liquid detergent in the beaker, let it stand at room temperature for 3 hours, then wash it with clean water 3 to 5 times, and let it dry in the air. Mildew stains on the fabric can be removed after drying.

Embodiment 3

[0031] The liquid detergent obtained in this example is composed of the following components: a mixture of sodium lactate and urea (mass fraction 10%) with a mass ratio of 1:1, a mass fraction of 3% hydrogen peroxide, a mass fraction of 87% water, and a pH of 7 .0.

[0032] Operation process:

[0033] Take 10mL of the obtained liquid detergent and put it into a small beaker, immerse the moldy cloth (chemical fiber, cotton cloth, colored cotton cloth) in the liquid detergent in the beaker, let it stand at room temperature for 24 hours, then wash it with clean water 3 to 5 times, and let it dry in the air. Mildew stains on the fabric can be removed after drying.

Abstract

The invention belongs to the field of daily-use chemical application, and discloses an environmental-friendly method for removing mold spots on clothes by using a deep eutectic solvent. The environmental-friendly method comprises the following steps: firstly, soaking clothes with mold into liquid with the deep eutectic solvent for a certain time at the room temperature, washing with clean water, and drying, thereby removing the mold spots on the clothes. By adopting the environmental-friendly method, the mold spots on the clothes can be effectively removed, the whole process is gentle, simple and low in cost, and defects that a conventional clothes bleaching method has large irritation on skin of human bodies, is not environmental-friendly and the like can be overcome.

Description

technical field [0001] The invention belongs to the application field of daily chemical industry, and in particular relates to a green method for removing mildew spots on clothes by using a deep eutectic solvent of choline chloride or lactic acid. Background technique [0002] In the humid season, moldy clothes are a common problem, especially in southern regions with high air humidity. All kinds of clothes are prone to moldy, especially for more expensive clothes. If mild and effective methods cannot be used to remove enzyme spots, then Had to cause waste by discarding. At present, the products for removing mildew on clothes are mainly bleaching agents, including two types of oxygen bleaching and chlorine bleaching. Chlorine bleaching is to use the oxidation of sodium hypochlorite to destroy dye stains and dye structure, so as to achieve the effect of bleaching, such as Blue Moon's "blue moonlight white clothing color stain net". Chlorine bleaching is mainly used to remov...
