Antimicrobial superfine fibre nonwoven cloth embedded with nano silvery

Abstract

The invention discloses an anti-bacterial superfine fiber non-woven fabric of an embedded nano-silver, which is weaved with the superfine fibers of the embedded nano-silver. The each superfine fiber consists of an outer layer and an inner core, the material of the outer layer is biocompatible polymer material, the material of the inner core is nano-silver. The diameter of the fiber is 200 nanometers to 10 microns, the diameter of the inner core is 1 / 3 to 2 / 3 of the diameter of superfine fiber , the size of the nano-silver particle is 5 to 30 nanometers. The invention has a significant effect on sterilization, inhibiting bacteria, diminishing inflammation and promoting wound healing, can be directly applied on the affected areas and is particularly suited for the burn and scald treatment; the biocompatible polymer material of the outer layer can be degraded. After treatment, the applied layer is no longer needed to be taken off, which saves the taking off step, and also avoids the bleeding phenomenon during the taking off process and the pain of patients; also has releasing function.

Description

technical field [0001] The invention relates to a medical dressing, in particular to an antibacterial superfine fiber non-woven fabric embedded with nano-silver. Background technique [0002] Silver itself has a wide range of bactericidal effects, can kill hundreds of bacteria, and silver itself is not toxic. At present, nano-scale fine particles of nano-silver made by nanotechnology make silver more active and enhance silver's antibacterial and anti-inflammatory capabilities. Nano-silver is widely used in the medical field, for example, for the treatment of gynecological diseases. For anti-inflammation, promoting wound healing, etc., nano-silver fine particles or silver ion aqueous solution have significant bactericidal effects, and have significant inhibitory effects on Escherichia coli, Staphylococcus aureus, etc. [0003] If nano-silver is used for external application, the direct external application needs to be wrapped with gauze, and the dressing needs to be changed ...
