Abstract

The invention belongs to the technical field of composite fibers and specifically relates to a preparation method of a graphene-polyester nanometer composite fiber. A spinning box used in the preparation method of the graphene-polyester nanometer composite fiber is provided with a box body, a rotating disc and an air guide rod; a spinneret plate is arranged in a position, close to the upper surface of the box body, in the box body; a conduit is fixedly connected to the lower surface of the spinneret plate; a cold plate is fixedly connected to the position, close to the lower end surface of theconduit, in the box body; the air guide rod is connected to the interior of the cold plate to slide from left to right; and the rotating disc is rotationally connected to the interior of the conduit.Through adoption of the preparation method of the graphene-polyester nanometer composite fiber, parallel airflow cooling of spun fibers is effectively realized, the wind direction and the fibers areprevented from being in a vertical state, uneven air speed is very easy to cause air turbulence to cause a filament drifting problem, and meanwhile, the cooling effect on the spun fibers is more uniform so that the cooling time of the spun fibers and the drawing ratio are kept consistent with each other; and therefore, the qualities of the prepared spun silks are higher.

Description

technical field

[0001] The invention belongs to the technical field of composite fiber production, in particular to a preparation method of graphene-polyester nano composite fiber. Background technique

[0002] Graphene is the thinnest two-dimensional nanomaterial known so far. Its lattice is a hexagonal 2 shape surrounded by six carbon atoms, with a thickness of one atomic layer. The carbon atoms are connected by s-bonds. sp hybridization, these s bonds endow graphene with extremely excellent mechanical properties and structural rigidity. The strength of graphene is 100 times stronger than the best steel. Graphene has high conductivity and is the smallest resistivity in the world. Material; graphene is also a very good antibacterial material, based on the mechanical properties of graphene, graphene can be added to the polymer matrix, which can improve the mechanical properties of the material, such as tensile strength, modulus, hardness etc.; based on the excellent electri...
