Abstract

The invention provides a nano-silver antibacterial fabric and a preparation method thereof. The nano-silver antibacterial fabric has the characteristics that a zinc oxide nano line grows on the fabric; and silver nano particles are deposited on the zinc oxide nano line. The zinc oxide nano line is synthesized by a solution chemical method; and the silver nano particles are deposited on the zinc oxide nano line by a simple 'immersion-illumination' method. The nano-silver antibacterial fabric prepared by the method has extremely obvious long-time antibacterial performance; the silver nano particles are small in size and cannot be accumulated; a synthesis process is environment-friendly; and the nano-silver antibacterial fabric can be recycled and reused. The nano-silver antibacterial fabric can be used for single-point water treatment to reduce microorganism content in water and can be suitable for medical surgical dressing and medical fabrics; and the nano-silver antibacterial fabric can be used as an antibacterial air filtration device for preventing bio-aerosol from being gathered on a ventilating, heating and air conditioning system.

Description

technical field

[0001] The invention relates to a silver-based antibacterial fabric and a preparation method thereof, belonging to the technical field of antibacterial textiles. Background technique

[0002] The invention of antibiotics has saved countless lives and is one of the most important events in human history. However, the abuse of antibiotics will lead to the decline of human resistance to diseases through immunosuppression, and at the same time, the resistance of bacteria will continue to increase. Recently, due to the emergence of a new type of bacteria, the world's attention to drug resistance has risen sharply. This superbug named NDM-1 has shown extremely high resistance to almost all antibiotics. The theme of World Health Day 2011 is "No Action Today, No Drugs Available Tomorrow", focusing on the increasingly serious problem of bacterial resistance to antibiotics, and calling for global policy responses to combat the flood of antibiotics. The development of...
