Abstract

The invention discloses a modified white graphene and polyester composite fiber and a preparation method thereof. The composite fiber is prepared from, by mass, 84%-99% of polyester chips, 0.1%-15% ofwhite graphene and 0.1%-1% of a modifying agent. The preparation method includes: step 1, weighing raw materials; step 2, drying the polyester chips and the white graphene, grinding the polyester chips into powder, adding the white graphene powder and the modifying agent into the polyester chip powder, mixing and stirring; step 3, adding the white graphene and polyester mixed powder into a twin-screw extruder, and performing extrusion granulation; step 4, drying modified white graphene and polyester masterbatch, adding into the twin-screw extruder, heating for melting, filtering through a spinning manifold, and spinning to obtain the modified white graphene and polyester composite fiber. The composite fiber prepared according to the method has advantages of antibacterial, far infrared andanti-ultraviolet functions, the added value of polyester can be increased, and a utilization range of polyester fibers is expanded.

Description

technical field [0001] The invention relates to a composite fiber and a preparation method thereof, in particular to a modified white graphene polyester composite fiber and a preparation method thereof. Background technique [0002] "White graphene" is an alias for the nano-flakes obtained after exfoliation of hexagonal boron nitride (English name Hexagonal Boron Nitride, abbreviated as h-BN) whose grains are lamellar structures. Since the structure of hexagonal boron nitride is very similar to that of graphite, it has a hexagonal layered structure, soft texture, strong machinability, and white color. Corresponding to graphene, so hexagonal boron nitride is called "white graphene". [0003] Both hexagonal boron nitride and graphene are layered two-dimensional materials with a thickness of only one atom. , Covalent bonding between heteroatoms of nitrogen. [0004] The highly similar crystal structure gives white graphene and graphene some common characteristics, such as ex...
