Problems solved by technology

Commonly used physical methods include friction and pyrolysis. The synthesis process not only requires a lot of energy to maintain high temperature and pressure, but also is slow and expensive; traditional wet chemical methods often use expensive and toxic reagents as reducing agents and stabilizers. A large amount of unreacted reagents remain in the solution, which pollutes the environment and does not conform to the current concept of green environmental protection.

Abstract

The invention relates to a nano-gold antibacterial blended fabric. The nano-gold antibacterial blended fabric is manufactured by the following steps: mixing a 0.01-10g/L dialdehyde chitosan solution and a 0.01-100g/L chloroauric acid solution in a volume ratio of 10:1 to 1:1, performing ultrasonic treatment at the temperature of 20-80 DEG C for 1-10 hours to obtain a nano gold colloid solution, preparing a 0.01-10g/L nano gold solution, immersing a blended fabric into the nano gold solution, and dipping twice and rolling twice. According to the invention, dialdehyde chitosan is taken as a reducing agent and a stabilizer of nano gold, thereby achieving the advantages of simple process, mild reaction, environmental friendliness and the like. The antibacterial cotton/cashmere/spun silk fabric manufactured by dipping twice and rolling twice can have the antibacterial rate of 99%, and is excellent in washability.
