气凝胶，是世界上目前已知密度最小的纳米级多孔结构固体材料，密度仅为3.55千克每立方米，由于其内部绝大部分成分为气体，看上去呈现出云雾状，因此，气凝胶又被称为“固态的烟”。

Aerogel is the solid material with the smallest known density at the nanoscale porous structure in the world, with a density of only 3.55 kilograms per cubic meter. Due to the fact that the majority of its internal components are gas, it appears in a cloud-like state. Therefore, aerogel is also known as "solid smoke".

      1932年，美国化学家Samuel Stephens Kistler首次利用超临界流体干燥技术制备出气凝胶，它创下十余项吉尼斯纪录，在热学、光学、电学、力学、声学等领域显现出许多奇特的性能，被称为“改变世界的神奇材料”。

In 1932, American chemist Samuel Stephens Kistler first prepared aerogel using supercritical fluid drying technology. It set more than ten Guinness World Records and demonstrated many peculiar properties in the fields of thermology, optics, electricity, mechanics, acoustics, etc., and was called "the magical material that changed the world".

      早在1997年的时候，美国就首次把气凝胶用到了火星探测器上，从此气凝胶成为航空航天领域里不可替代的隔热材料。

As early as 1997, the United States first applied aerogel to Mars probes, and since then, aerogel has become an irreplaceable insulating material in the aerospace field.

AIREPAI ® aerogel cold-resistant fiber/yarn features outstanding properties such as light weight, heat storage and temperature retention, long-lasting antibacterial effect, moisture permeability and breathability. Compared with the same material, its density is over 12% lighter. At low temperatures, its heat insulation performance is more than five times that of cotton fabric, and the fiber insulation rate is better than that of cashmere material. It can maintain its heat insulation and heat preservation performance for a long time in extreme environments above -20℃.

1、材质轻盈The material is lightweight.

气凝胶是世界上目前密度最小的纳米级多孔固态材料，将气凝胶通过微气态混合制备专利技术融入纤维基材，可以令到纤维呈现丰富的层叠纳米多孔形态，纤维整体密度可下降12%以上，纤维变的更加轻质蓬松、轻松告别厚重、臃肿，宛如空气般灵动。

Aerogel is currently the world's lightest nano-porous solid material in terms of density. By integrating the patented technology of preparing aerogel through micro-gas mixture into the fiber substrate, the fibers can present a rich layered nano-porous morphology. The overall density of the fibers can be reduced by more than 12%, making them lighter, fluffier, and easily bid farewell to being heavy and bulky, as dynamic as air.
