I heard about it recently. The friends have basically successfully "taken off the single".
Get off the list, get off the list
I'm finally out of the list.
I'm starting to wear two pieces now."
People haven't gone out yet.
When I opened the phone, my heart was half cool.
It's really cold!
To protect against the cold.
All kinds of down jackets and padded clothes have been dispatched
Oak when choosing warm clothing.
I've seen a lot of "high-tech" concepts.
AerogelCold-resistant clothingVolcanic rocksWarm cotton,
Graphene is self-heatingAir lock temperature
Are you confused?
Warm clothing is a combination of technology.
Is it scientific and technological innovation, or is it an "IQ tax" trap?
Let's take a look!
This winter, thermal clothing began to "technological involution"!
Some time ago, a domestic down jacket of 7,000 yuan attracted a lot of attention. Brand side"Skypeople".stated in the response,The use of technical fabrics is the main reason for the higher pricing, which was also listed in the statementWindproof, waterproof, lightweight technical fabric"."Volcanic rock anti-static lining"."Circulating moisture drainage and warmth preservation system".and other ready-to-wear technologies full of science and technology.
Thermal clothing with technical fabrics is becoming a new trend, attracting more and more technology clothing brands to enter the game.
Aerogel"We use itThe core thermal insulation of the spacesuit - aerogelThis is a new black technology, its heating capacity is twice that of ordinary cotton clothing....”
Open a live broadcast room that sells winter clothes, and you are likely to hear some words with black technology. Recently, some cutting-edge brands have begun to launch "aerogel cold clothing", claiming that it hasLightweight, breathable, resistant to moisture and cold, etcCharacteristics: Compared with traditional down, it has better pressure resistance and less heat loss.

Let's find out first.
What the hell is aerogel?
Aerogel is a kind of three-dimensional network structure material that envelopes a large number of closed microporesInorganic materialsorPolymer macromoleculesIt is made by a sol-gel transition process followed by a special drying process.
According to this definition, you can know,The concept of aerogel actually refers to a solid structure (not a chemical).The peculiarity of this structure is its high porosity, which is as high as 800%~99.8% with pore sizes ranging from 1 100 nm.
There is dispersed and stationary air in the closed micropores of the aerogel structure, which determines the performance characteristics of the substances with aerogel structure with low density and low thermal conductivity.
