Abstract

The invention discloses a preparation method of graphene/nano-carbon-black modified viscose fibers. Nano-carbon-black with a specific DBP value is compounded with single-layer graphene oxide accordingto a specific proportion, the graphene oxide is reduced in a heating alkaline environment to form a stable compound structure, the graphene oxide can be directly mixed with viscose spinning liquid after washing, good dispersion is kept, spinning is performed to obtain the novel viscose fibers with anti-static, anti-ultraviolet and anti-bacterial functions, product functions are stable and cannotbe attenuated along with washing, the fibers can be directly prepared on a viscose fiber production line, an original process is minimally changed, and the prepared fibers can be applied to underwear,coats, pants, socks and shoe materials.

Description

technical field [0001] The invention belongs to the field of chemical fiber fabrics, in particular to a preparation method of graphene / nano carbon black modified viscose fiber. Background technique [0002] Viscose fiber is a cellulose fiber. It is made of natural fibers (wood fibers, cotton linters) as raw materials, through alkalization, aging, sulfonation and other processes to make soluble cellulose xanthate, and then dissolved in dilute lye to make viscose. made by spinning. Because viscose fiber itself is extracted from natural wood cellulose, it has the characteristics of natural environmental protection, hydrophilic, breathable, cool and comfortable. However, with the improvement of people's living standards, new functional requirements have been put forward for viscose fibers, such as UV protection, heat generation, warmth retention, antibacterial and antibacterial, antistatic, etc. At present, the modification of viscose fiber is mainly to realize the above func...
