Embodiment Construction

[0011] Weigh AgNO 3 100 g, dissolved in 40 liters of water, concentrated NH 3 h 2 O500 ml, concentrated NaOH 50 g, NH 4 NO 3 500 grams to dissolve and mix well. Take 20 grams of glucose, dissolve it in 5 liters of water, add concentrated HNO 3 10 ml, 1.5 liters of ethanol. Mix these two solutions evenly, add 10 kg of activated carbon fiber and soak for 5 minutes, stir at room temperature to make it fully uniform, then add 1 liter of hydrogen peroxide and stir to make it wet. Take it out after 5 minutes, squeeze off the excess solution or shake it dry, put it into an oven for drying, and then rinse and dry it several times to obtain the product of the present invention.

Abstract

A process for preparing the antibacterial material which can be used to prepare the suppository for treating vaginal infections and cervical erosion with total effective rate up to 90% or more features that an ion exchange method is used to attach the combination of nano-class Ag and silver oxide to the surface of activated carbon fibres. Its advantage is high sterilizing power (15 mm for indirect sterilizing diameter).

Description

[0001] Field: [0002] The invention relates to a method for combining nano silver with fabrics, in particular to a method for making antibacterial materials by combining the antibacterial performance of nano silver with activated carbon fibers. Background technique: [0003] The long-acting and broad-spectrum antibacterial properties of nano-silver have been confirmed by scientists from many countries in the world and applied in clinical medicine. At present, nano-silver is combined with functional fabrics to heal various wounds clinically. Since the diameter of nano-silver sterilization is relatively small, the diameter of its antibacterial zone is about 2 mm, so the space for sterilization is relatively small and relatively passive. , and nano-silver is inseparable from the carrier of silver and silver oxide, while functional fabrics have relatively small adsorption, and even worse adsorption after contact with water, and their sterilizing diameter is 2mm-5mm. This require...
