Abstract

The invention provides a graphene-polyester composite master batch and a preparation method thereof. In the graphene-polyester composite master batch, the content of graphene relative to sliced polyester is 0.05 to 2 percent, and the content of bioprotein powder relative to the sliced polyester is 1.5 to 4.5 percent. The preparation method comprises the following steps: a preparation step of graphen-polyester composite powder, a preparation step of bioprotein-polyester composite powder and a mixing and extruding step. Graphene-polyester composite fiber prepared by adopting the graphene-polyester composite master batch prepared by the invention for spinning has softer hand feeling, better skin friendliness and good moisture absorption performance, and static electricity cannot be generated;meanwhile, a friction force between fiber and fiber is enlarged, a cohesive force is strengthened, and spinnability of polyester fiber is obviously improved.

Description

technical field [0001] The invention provides a polyester masterbatch and a preparation method thereof, in particular a graphene-polyester composite masterbatch and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional carbon nanomaterial in which carbon atoms form a hexagonal honeycomb lattice with sp² hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. [0003] In recent years, functional and differentiated fibers represented by graphene have developed rapidly. Modified and modified graphene is added to the production process of fibers, and the prepared graphene fibers have good strength, antibacterial properties and far-infrared Release functions, therefore, are gaining more and more attention from industry and soc...
