Preparation method for new antiviral and antibacterial polypeptide material

Abstract

The invention belongs to the technical field of antiviral and antibacterial materials, and discloses a preparation method for a new antiviral and antibacterial polypeptide material. The preparation method comprises the steps that a natural fabric or an artificial fabric is pretreated and washed up with a cleaning agent; suitable reaction conditions are selected, reactive groups, namely hydroxyl group and amino group, on the fabric are activated with a suitable chemical reagent; the dense density of the activated group on the fabric is detected, the activated fabric reacts with functional polypeptides under certain conditions, and the activated polypeptides are coupled to the fabric; the fabric is cleaned again to wash unreacted chemical substances and polypeptides off; the fabric is dried;the antiviral and antibacterial performance of the fabric is detected; and the detected antiviral and antibacterial polypeptide fabric is subjected to further deep processing. According to the fabricto which the antiviral and antibacterial polypeptides are attached, the fabric and the polypeptides can be firmly combined, and the fabric can be tolerant to multi-time washing and can keep the antibacterial and antiviral functions for a long time.

Description

technical field [0001] The invention belongs to the technical field of antiviral and antibacterial materials, and in particular relates to a preparation method of a novel polypeptide material with antiviral and antibacterial properties. Background technique [0002] At present, in response to large-scale public health emergencies, especially the prevention of sudden infectious diseases that are rapidly transmitted by bacteria and viruses, most of the protection is to strengthen personal protection, wear masks, protective clothing, etc., and at the same time strengthen environmental disinfection to kill the original disease. operate. In the field of personal protection, the basic function of masks and protective clothing is only to block and isolate the passage of pathogens, or to contaminate the surface of the human body, respiratory tract and digestive tract, which is a passive isolation function. [0003] In environments with a high risk of contamination by pathogens, suc...

AI Technical Summary

Problems solved by technology

[0005] Through the above analysis, the existing problems and defects of the existing technology are: in an environment with a high risk of contamination by the source of the disease, the source of the infection should be eliminated regularly; it often needs to be strengthened regularly, otherwise as the concentration of the disinfectant gradually decreases, The effect of killing the pathogen is also gradually reduced
