Description
Technical field
The present invention relates to underwear manufacture technology field, the production method of specifically a kind of graphene intelligent health-care underwear.
Background technology
Graphene is a kind of two-dimentional carbon material, is single-layer graphene, bilayer graphene and the general designation for lacking layer graphene.Graphite
Alkene is the nano material that known world is most thin, most hard, it is almost fully transparent, only absorbs 2.3% light；Heat conduction system
Number is up to 5300W/m.K, is higher than carbon nanotube and diamond, its electron mobility is more than 15000cm under room temperature2/ V.s, and compare
Carbon nanotubes or silicon crystal are high, and resistivity about 108Ω .m, it is lower than copper or silver, it is the material of world resistivity minimum.Cause
Its resistivity is extremely low, and the speed of electron transfer is exceedingly fast, therefore is expected to can be used to develop thinner, conductive speed of new generation faster
Electronic component or transistor.Since graphene is substantially a kind of transparent, good conductor, it also is adapted for for manufacturing transparent touch
Screen, tabula rasa, even solar cell.
Graphene is the two dimensional crystal material and structure carbon material the simplest of monoatomic layer.Common graphite material
Material is considered as being formed by graphene stacked in multi-layers, therefore graphene is also considered " mono-layer graphite ".It is known as " 21 century mystery
The graphene of material " is that current known world is most thin, most hard, electric conductivity is best at room temperature and possesses powerful flexibility
Nano material；It thin can arrive the only thickness there are one carbon atom, and 3,000,000 layers of stone can be separated in the graphite flake of 1 millimeters thick
Black alkene；It is very hard, 200 times more taller than steel of intensity；At room temperature, the minimum substance of resistivity is silver, and the electricity of graphene
Resistance rate is also smaller than silver；Various characteristics that it is transparent and airtight ... keep graphene future all in touch screen, sensor, accumulator etc.
Multi-field application is full of the imagination.
China is current graphene research and application and development one of country the most active.Data are shown, in All Countries
In, the graphene patent numbers of China's application are most, more than 2200, account for global 1/3.Currently, Chinese graphene is special
Sharp quantity the first in the world.
Underwear refers to the personal clothing worn, including vest, undershirt, shorts, brassiere etc., is typically to be in direct contact skin,
It is indispensable one of the dress ornament of modern.Underwear has absorbing sweat, rectifys type, set off body, is warming and not by filthy from body
The effect of harm, is considered as sex character sometimes.Underwear is substantially inclusiveness to be had, and could effectively give breast and stern in this way
Portion is with supporting force.Whether underwear has this characteristic, is related to forming the material of underwear and the frame mode of material：With knitting
Mode carrys out organization material, ineffective material be silk, cotton, chemical fibre, it is blended, them can all generated very strong
Contractility, i.e. our traditionally described elasticity；And the knitting fabric of double-layer structure, elasticity are better than single layer again.In some
Clothing is expensive, some underwears come from a master's hand, and once effect is distinguished for some underwears, but regardless of the underwear of sample,
Wear, wash, drying in the air, receive during all can it is fast or slowly lose it is original possessed by function, underwear at this time even can play anti-work
With the amendment bodily form is not only unprofitable to one by one, figure can be distorted instead.
It is preferably natural fibre products to select underwear.It is wherein more suitable with cotton products.Its hygroscopicity and warmth retention property is good
Well, price is also moderate.Their hygroscopicity such as the product of synthetic fibers such as polyamide fibre underpants, terylene shirt are poor, are unfavorable for human sweat
Absorption and distribute, it is difficult to adjust the moist heat between skin and underwear, therefore wear next to the skin often and have sultry feeling.Its
Notable to be synthetic fibers underwear can also cause skin injury, the harm of nylon from remaining monomer phthalein amine in oneself,
It can cause dry skin, it is coarse, thicken, or even occur relatively to split, dermatitis etc..In addition it has antigenicity to skin, so as to cause
Allergic reaction.
