Abstract

The invention belongs to the field of functional fiber materials, and discloses a graphene multifunctional viscose fiber and a preparation method thereof. The preparation method comprises the steps ofmixing the graphene and functional nanparticles after ball-milling erosion punching pretreatment with a viscose spinning solution, carrying out wet spinning to obtain nascent fibers, drawing the nascent fibers, and then sequentially carrying out cutting and post-treatment to obtain the graphene multifunctional viscose. The invention can endow viscose fiber with the health functions of negative ions, far infrared, antibacterial and ani-mite, magnetism, formaldehyde removal, peculiar smell removal, radiation resistance, ultraviolet resistance and the like. And the ball-milling erosion punchingpretreatment is carried out on the graphene and the functional nanoparticles, so that the compatibility and the dispersion stability of the graphene and the functional nanoparticles and the viscose fiber matrix can be obviously improved, and the corresponding functional effects can be ensured to be exerted persistently and stably.

Description

technical field [0001] The invention belongs to the field of functional fiber materials, and in particular relates to a graphene multifunctional viscose fiber and a preparation method thereof. Background technique [0002] The hygroscopicity of viscose fiber meets the physiological requirements of human skin. It has the characteristics of smooth and cool, breathable, antistatic, anti-ultraviolet, colorful and good color fastness. It has the essence of cotton and the quality of silk. It is an authentic plant fiber, derived from nature and superior to nature. Widely used in various underwear, textile, clothing, non-woven and other fields. [0003] Viscose fiber is mainly made of high-purity cellulose dissolving pulp prepared from cellulose derived from cotton linters, wood, and plant straw through a series of processes such as acid hydrolysis, alkali hydrolysis, and bleaching. It is prepared through a series of steps of alkali impregnation, pressing, aging, yellowing, disso...
