Abstract

The invention discloses a method based on a polyethyleneimine-silver ion chelate for preparing an antibacterial plush product. The method comprises the following steps that 1, an antibacterial treating agent is prepared; 2, epoxidation is performed on a plush product; 3, polyethyleneimine (polyethyleneimine) is grafted on the surface of the plush product processed through the step 2; 4, the plush product grafted with the polyethyleneimine through the step 3 is chelated with nano-silver particles in the antibacterial treating agent; 5, the plush product processed through the step 4 is washed with deionized water for three times to remove the antibacterial treating agent floating on the surface of the plush product, the plush product is dried in an air blowing oven with the temperature of 60 DEG C after being washed, and the antibacterial plush product is obtained. According to the method, the initial bacteriostasis rate of the prepared plush product for bacillus subtilis and escherichia coli is up to above 95 percent, and the bacteriostasis rate for the bacillus subtilis and the escherichia coli is still up to above 80 percent after six months.

Description

technical field [0001] The invention relates to the field of antibacterial treatment, in particular to a method for preparing antibacterial plush products based on polyethyleneimine / silver ion chelate. Background technique [0002] Plush toys are widely loved by children, and plush crafts (such as pillows, throw pillows, cushions, home accessories, etc.) are also closely related to the daily life of adults. However, due to their fluffy and dense structure, plush products are easy to hide dirt and breed mites, and are good places for various bacteria and microorganisms to multiply, so it is particularly important to regularly sterilize them. [0003] Commonly used antibacterial treatment agents can be divided into three types, including inorganic, organic and natural biological antibacterial agents. Organic products mainly include quaternary ammonium salts, alcohol phenol ethers and pyrroles, etc. Their advantages are strong bactericidal power and various types, but their di...
