Embodiment 1

[0009] Example 1: Take 95.76% of PET bottle flakes, 0.02% by weight of whitening agent, 4% by weight of modified graphene masterbatch, and 0.22% by weight of silicone oil agent. First, clean the raw materials, separate the color and impurities, and then measure the ingredients, add 0.02% whitening agent and 4% graphene masterbatch, after continuous drying, the water content reaches below 50PPM and then melt spinning, add 0.5% ordinary oil agent, winding and oiling, feeding into the barrel, clustering, drawing, crimping, adding silicone oil agent, cutting, drying and shaping, and finally packing.

Embodiment 2

[0010] Example 2: Take 95.8% of PET bottle flakes, 0.02% by weight of whitening agent, 4% by weight of modified graphene masterbatch, and 0.18% by weight of silicone oil agent. First, clean the raw materials, separate the color and impurities, and then measure the ingredients, add 0.02% whitening agent and 4% graphene masterbatch, after continuous drying, the water content reaches below 50PPM, then melt spinning, add 0.5% ordinary oil agent, winding and oiling, feeding into the barrel, clustering, drawing, crimping, adding silicone oil agent, cutting, drying and shaping, and finally packing.

Embodiment 3

[0011] Example 3: Take 95.78% of PET bottle flakes, 0.02% by weight of whitening agent, 4% by weight of modified graphene masterbatch, and 0.20% by weight of silicone oil agent. First, clean the raw materials, separate the color and impurities, and then measure the ingredients, add 0.02% whitening agent and 4% graphene masterbatch, after continuous drying, the water content reaches below 50PPM, then melt spinning, add 0.5% ordinary oil agent, winding and oiling, feeding into the barrel, clustering, drawing, crimping, adding silicone oil agent, cutting, drying and shaping, and finally packing.

Abstract

The invention provides a graphene three-dimensional hollow polyester staple fiber and a production method thereof. The graphene three-dimensional hollow polyester staple fiber is prepared from, by weight, 95.76%-95.8% of PET bottle grade, 0.02% of brightening agent, 4% of modified graphene master batch and 0.18%-0.22% of silicone oil; the production method comprises the steps that firstly raw materials are washed, color separation and impurity separation are carried out, then computation batching is carried out, 0.02% of the brightening agent and 4% of the graphene master batch are added, continuous drying is carried out, melt spinning is carried out after the moisture achieves to less than 50 PPM, 0.5% of general oiling agent is added, winding and oiling are carried out, the fiber is input and falls into a bucket, beam concentration is carried out to generate a yarn, drafting and crimping are carried out, then cutting, drying and setting are carried out after a silicon oil agent is added, and finally packaging is carried out.

Description

technical field [0001] The invention relates to the field of three-dimensional hollow short fiber materials, in particular to a method for manufacturing graphene three-dimensional hollow polyester short fibers. Background technique [0002] Graphene, a new material in the 21st century, is an epoch-making innovation that subverts global material science. Graphene has the characteristics of high strength, high modulus, light weight, ultra-thin, and flexibility. It has excellent light transmission, Transparency, electrical conductivity, thermal conductivity, energy storage, antibacterial, UV protection, and antistatic properties. Since graphene is a sheet of two-dimensional nanoparticles without molecular chains similar to high polymers, it is difficult to directly prepare graphene fibers. At present, many preparations of graphene fibers are still limited to the laboratory stage, and it is far from practical application and popularization. Making full use of the characteristi...
