▎ 摘  要

NOVELTY - Preparing modified white graphene terylene composite fiber comprises (i) preparing ethanol solution, adding dopamine and stirring evenly, adding white graphene into the solution, ultrasonically dispersing, filtering and drying to obtain modified white graphene powder, (ii) respectively drying the modified white graphene powder and common terylene slice, grinding the terylene slice to obtain terylene slice powder, adding the dried modified white graphene powder and modifier into the terylene slice powder, and mixing and stirring to obtain white graphene terylene mixed powder, (iii) adding the obtained white graphene polyester mixed powder into a twin-screw extruder, extruding, and granulating to obtain modified white graphene terylene masterbatch, and (iv) drying the obtained modified white graphene terylene masterbatch, adding it into the screw extruder to heat and melt, spin filtering by a spinning box, and spinning into a bundle to obtain final product. USE - The method is useful for preparing modified white graphene terylene composite fiber. ADVANTAGE - The method: modifies the white graphene to improve the dispersibility of the white graphene in the regenerated cellulose pulp; and has better exerting the function of regenerated cellulose composite fiber. The composite fiber: has antibacterial, far-infrared and anti-ultraviolet properties, and long-lasting functionality; utilizes the white grapheme, which is evenly dispersed; and does not easy to fall off. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for modified white graphene terylene composite fiber prepared by above method.
