Abstract
Description
Technical Field
[0001] The invention relates to a textile printing and dyeing stain remover, in particular to a stain remover acting on medical protective equipment under low temperature conditions, and a preparation method of the stain remover for medical protective equipment. Background Art
[0002] Grease dirt, including non-water-soluble substances such as animal and plant oils, mineral oils, human metabolites sebum, and drug stains, can be firmly adsorbed on the surface of medical protective products and are insoluble in water due to the strong interaction between the hydrophobic base of this type of dirt and the fabric fibers. Grease dirt can be dispersed in the detergent by the emulsification effect of organic solvents or surfactants. Blood stains, especially protein dirt that is denatured and coagulated in the gaps of fabric fibers, can be decomposed and washed by corresponding enzymes. One of the important links in the repeated use of medical protective products is washing, but there are relatively few detergents for medical protective products that are specially used. Ordinary detergents have poor cleaning effects on special dirt such as sebum, blood stains, and drug stains. Moreover, since most of the corresponding detergents on the market are treated under high temperature and strong alkaline conditions, they have a greater impact on the strength of the fabric surface and consume energy. Therefore, in order to obtain a better washing effect, it is necessary to develop a stain remover suitable for use under low temperature conditions for medical protective products, which has good practical value and broad market prospects. Summary of the invention
[0003] The purpose of the present invention is to solve the problem of removing stains on medical protective equipment under low temperature conditions, and on this basis to provide a stain remover with low intensive damage to medical protective equipment.

The surfactant is any one of a special reactive hydroxy alcohol alkoxylate, coconut oil methyl monoethanolamide, a composite carbon chain branched alcohol ether, and a straight-chain alcohol, or a combination of more than one of them.
[0005] The protease described in the present invention is a serine protease.
[0006] The protease stabilizer described in the present invention is borax or propylene glycol, or a combination of both.
[0007] The solvent described in the present invention is anhydrous ethanol.
[0008] The dispersant described in the present invention is an acrylic dispersant.
