Antibacterial functional fibers

Abstract

The invention relates to antibacterial functional fibers and belongs to the field of polymer material. In the invention, carrier fibers and aqueous solution of an inorganic metal antibacterial agent are mixed and stirred at a constant temperature of 0 to 100 DEG C for 10 minutes to 24 hours first, then the fibers are taken out and washed by deionized water till the pH value of the fibers is 6.5 to 7.5, and finally the fibers are dried at 40 to 60 DEG C to give the target product. In the invention, the raw materials are widely available, the synthesis process is simple, the synthesis process is easy to control, and industrial production is easy to realize. The fibers have a broad antibacterial spectrum and long-lasting antibacterial performance, is safe and reliable, and can be made into health-care underwear, insoles, operation clothes, nurse clothes, medical gauzes and the like. The fibers can also be made into nonwoven fabrics used for making filter elements of air purifiers for killing bacteria and germs in the air, and therefore have a promising application prospect.

Description

technical field The invention relates to a functional fiber with antibacterial properties, which belongs to the field of polymer materials. Background technique Silver, copper, zinc, iron, chromium, nickel, mercury, lead and other metals and their ions all have the function of sterilizing or inhibiting the growth of bacteria. As early as more than two thousand years ago, the ancient Egyptians used thin silver foil to treat wounds. For medical treatment and to prevent ulcers, Chinese Mongolian herdsmen also use copper pots to hold mare's milk to prevent it from going bad. Among many metals, silver has the best antibacterial effect, ranking first, and the others are Ag>Hg>Cu>Cd>Cr>Ni>Pb>Co>Zn>Fe (He Xiuling, Guo Lamei. Nano silver-loaded inorganic Antibacterial agents and their application in textiles [J]. Shanghai Textile Science and Technology, 2003, 31 (3): 54-55). Antibacterial agents of various inorganic metal ions have been prepared one after...
