Graphene blend regenerated cellulose fiber and preparation method thereof

Abstract

The invention relates to a graphene blend regenerated cellulose fiber. The graphene blend regenerated cellulose fiber is prepared by mixing an oxidized graphene solution and a regenerated cellulose solution, molding a mixture through a viscose wet spinning process and reducing the mixture; the dry breaking strength of the graphene blend regenerated cellulose fiber is not less than 1.8 cN / dtex, the wet breaking strength of the graphene blend regenerated cellulose fiber is not less than 0.9 cN / dtex, the dry breaking elongation of the graphene blend regenerated cellulose fiber is not less than 16%, the mass specific resistance of the fiber is 1-9X106 omega.g / cm2, and the thermal decomposition temperature of the fiber is not lower than 400 DEG C; and with the regenerated cellulose fiber as a matrix, the prepared graphene blend regenerated cellulose fiber has the advantages of good moisture absorption, good air permeability, soft handle and good dyeing performance and has the characteristics of ultrahigh strength, thermal conductivity, electric conductivity, antibacterial property and the like of the graphene; the conductive and thermal properties of the fiber are both improved by being compared with those of the traditional regenerated cellulose fiber; the antibacterial property of the fiber is additionally provided; and the graphene blend regenerated cellulose fiber provided by the invention has the advantages of simple production process, easiness in operation, and higher yield. People estimate that the developed graphene blend regenerated cellulose fiber can be widely applied to the field of costumes, industrial textiles and the like.

Description

technical field

[0001] The invention relates to a graphene blended regenerated cellulose fiber and a preparation method thereof, belonging to the technical field of textiles. Background technique

[0002] Functional fibers can effectively increase the added value of its textile products, enhance the function and grade of textile products, and meet the diversified needs of clothing. Therefore, the development and design of new functional fibers has become a research hotspot in the textile industry, including high temperature resistance Combustible, antibacterial and deodorant, heat preservation and heat storage, antistatic, anti-ultraviolet, high moisture absorption and water absorption and green environmental protection and other functional fibers.

[0003] Regenerated cellulose fiber has similar wearing properties to cotton fiber, and can be grafted and functionally finished through the chemical reaction of hydroxyl groups on its macromolecules, so it is usually used as a m...
