Abstract

The invention provides a preparation method of a chitosan fabric based on graphene foam modification. The preparation method comprises the following steps: blending chitosan fibers and chitooligo saccharide fibers to form blended yarns, soaking the blended yarns into a solution with 3-chlorine-2-hydroxypropyl trimethyl ammonium chloride, performing heating stirring and ethanol washing, and drying to obtain quaternary ammonium salt modified chitosan and chitooligo saccharide blended fibers; weaving the quaternary ammonium salt modified chitosan and chitooligo saccharide blended fibers serving as a raw material to prepare the chitosan fabric; soaking the chitosan fabric into a graphene oxide solution, oscillating, taking out, drying and curing the fabric, then soaking the fabric in finishing liquid with a reducing agent and nanometer titania, performing heating reaction, taking out the fabric, drying in vacuum, washing to remove substances which are combined to the surface loosely, and drying to obtain the chitosan fabric based on graphene foam modification.

Description

Technical field [0001] The invention belongs to the technical field of textile materials, and specifically relates to a preparation method of a chitosan fabric modified based on graphene foam. Background technique [0002] With the increase of people's health and health awareness, multifunctional green fabrics are more and more popular among consumers. Polysaccharide is a natural polymer compound. Chitin is a natural polysaccharide extracted from the shells of shrimps and crabs and fungal agent algae cell walls. Chitosan is deacetylated chitin. Chitosan has high biological activity. Chitooligosaccharides are also known as chitosan. Chitosan is a chitosan with a low degree of polymerization. With the decrease of molecular weight, chitosan has some characteristics of chitosan, but also shows more excellent water solubility. The development of fabric products based on chitosan and its derivatives has many properties, such as moisture absorption and water-locking properties, antibac...
