Problems solved by technology

Synthetic fiber products such as nylon underwear and polyester shirts have poor hygroscopicity, which is not conducive to the absorption and distribution of human sweat, and it is difficult to adjust the microclimate environment between the skin and underwear, so it often feels stuffy when worn next to the body

Abstract

The invention discloses a production method of graphene intelligent health-care underwear. The production method comprises the following specific steps: adding graphite powder into concentrated sulfuric acid to obtain a graphene concentrated sulfuric acid solution; adding strong phosphoric acid, potassium permanganate, potassium dichromate, deionized water and hydrogen peroxide to obtain a modified graphene solution; then preparing to obtain modified graphene suspension; degumming, dissolving, dialyzing, purifying and filtering silk fibers to obtain a pure silk fibroin solution and preparing into regenerated silk fibers; depositing the modified graphene suspension onto the surfaces of the regenerated silk fibers under the action of high-pressure electrostatic atomization; heating and curing under the protection of inert gas to obtain graphene modified silk fibers; producing an underwear body to obtain the graphene intelligent health-care underwear. The graphene intelligent health-careunderwear produced by the preparation method, disclosed by the invention, has antibacterial properties, anti-ultraviolet properties, far-infrared properties and the like; the produced underwear has the advantages of excellent heat conduction and anti-bacteria property, far-infrared health-care properties and the like; blood circulation of a body is favorably accelerated and surface temperature ofthe skin is increased; in addition, the effects of the underwear are not declined after being washed for multiple times.

Description

technical field [0001] The invention relates to the technical field of underwear production, in particular to a production method of graphene intelligent health care underwear. Background technique [0002] Graphene is a two-dimensional carbon material, which is a general term for single-layer graphene, double-layer graphene and few-layer graphene. Graphene is the thinnest and hardest nanomaterial known in the world. It is almost completely transparent and only absorbs 2.3% of light; its thermal conductivity is as high as 5300W / m.K, which is higher than that of carbon nanotubes and diamonds. Its electron migration at room temperature rate over 15000cm 2 / V.s, which is higher than that of carbon nanotubes or silicon crystals, and the resistivity is only about 10 8 Ω.m, lower than copper or silver, is the material with the smallest resistivity in the world. Because of its extremely low resistivity and extremely fast electron migration, it is expected to be used to develop a...
