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-antibacterial fabric. The nano-antibacterial fabric is manufactured by the following steps: mixing a 0.01-1g / L silk fibroin solution and a 0.01-100g / L chloroauric acid solution in a volume ratio of 10:1 to 1:1, adjusting the pH value of the mixture to be equal to 10, performing ultrasonic treatment at the temperature of 20-80 DEG C for 1-10 hours to obtain a nano gold colloid solution, immersing a fabric into a nano gold solution with concentration of 0.01-10g / L, and dipping twice and rolling twice. According to the invention, fibroin 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 fabric manufactured by dipping twice and rolling twice can have the antibacterial rate of 99%, and is excellent in washability.
