This material is used from the crowdfunding of JD.COM Supai Aerospace series winter clothes to Bosideng down jacket. How amazing is this material? Bosideng official said: "The protective bag is made of aerospace nano-thermal insulation material aerogel, which effectively prevents electronic instruments from accelerating power loss due to low temperature."
That is to say, in extremely cold conditions, aerogels should be used as protective bags to protect electronic instruments from low temperature, instead of relying on super 5A white goose down to keep out the cold. This is the defect of down jacket. ...
To keep down jackets warm, there must be a prerequisite, that is, the environment must be stable and dry. Because down has not been sorted or woven, once it gets wet in water, it will shrink and collapse, and its volume may become one tenth or even smaller. In this case, the warm-keeping effect will be reduced to one tenth or even less until the warm-keeping function is completely lost, which is basically equivalent to "streaking".
"Encountering water" is not limited to external factors such as rain or snowfall. Sweat during exercise and water vapor naturally emitted during a nap are listed. Once the down is wet, it loses its meaning.
Another fatal defect of down is that it is not resistant to cleaning and is not easy to store. Frequent washing will crush and agglomerate, and continue to reduce the thermal insulation performance until it is lost. Moreover, if the water vapor can't dissipate completely after cleaning, it is easy to mold and breed bacteria, and it can't be squeezed and folded continuously, and the elasticity of down will be damaged.
Then, let's talk about this aerospace material used in Bosideng protective bag-aerogel. Aerogel is known as the lightest solid known to mankind and has broken more than ten Guinness World Records. Its thermal conductivity reaches 0.0 14W/M.K, which is lower than the 0.026W/m.k material used by NASA to make spacesuits.
As far as I know, Lanqire, the earliest aerogel composite material for textile in China, was developed by Shu Bonami Co., Ltd. and applied to the clothing industry in cooperation with Supai Technology. Obtained the first aerogel clothing patent officially put on the market in China, and became the pioneer of aerogel clothing in China. Aerogel winter clothing solves the inherent disadvantages of traditional warm clothing, and has the characteristics of ultra-light, extreme cold resistance, wet cold resistance, easy cleaning and mildew resistance. The thermal insulation effect of aerogel material with a thickness of 3mm is equivalent to that of down with a thickness of 40mm, and it is lighter, thinner and easier to cut. In contrast, the traditional down warm clothing can no longer meet people's diverse material needs, and aerogel clothing will be a new type of warm clothing that subverts tradition and changes 2 1 century.
