Abstract

The invention belongs to the field of functional textiles, in particular to an antibacterial graphene oxide nanocomposite fabric and a preparation method thereof. Polyethyleneimine was grafted on the surface of graphene oxide to modify it to avoid its aggregation in aqueous solution. Green synthesis of nano-silver loading and graphene oxide surface, using ultra-pure water as solvent, dissolving nano-composite material in water as spinning solution, using electrospinning technology, spraying the material on cotton to form antibacterial cotton yarn, will get The yarns are woven horizontally and vertically as warp and weft yarns to form a fabric. In the invention, the nanocomposite material is mixed and spun into the fabric, so that the fabric has high-efficiency antibacterial and deodorizing effects, and the green synthesis process protects the ecological environment.

Description

technical field [0001] The invention belongs to the field of functional textiles, in particular to an antibacterial graphene oxide nanocomposite fabric and a preparation method thereof. Background technique [0002] Cotton textiles have the advantages of excellent air permeability, moisture absorption, heat resistance, flexibility and recyclability. Cotton fabrics provide a good growth environment for microorganisms due to their ability to easily retain moisture. Metabolic products on human skin provide bacteria with sufficient nutrients. Textiles are closely related to human activities. The bacteria that breeds may bring health risks to humans through various ways. The antibacterial effect of traditional antibacterial textiles is not significant, so it is of great practical significance to develop new antibacterial cotton textiles. Due to their excellent properties, nanomaterials are increasingly used in the field of biomedicine and become the carrier of antibacterial act...
