Aerogel fibers, which have extremely high thermal insulation, moisture absorption and breathability properties, also have a wide range of applications. It is obvious that it is used to make cold-proof clothing, sportswear, etc. With the further development of textile fiber technology, products made of aerogel fibers, such as parts of spacesuits, can be applied in the aerospace field.
     Those who enjoy outdoor activities and are passionate about mountain climbing, exploration and crossing cannot avoid the issue of their own safety in the complex outdoor environment, especially in low-temperature conditions. According to the data from the laboratory, the heat insulation performance of aerogel fibers at low temperatures is 2.8 times that of cotton cloth. Their enthalpy value can reach 162 J/g, and they can maintain their heat insulation and heat preservation performance for a long time in extreme environments ranging from -196 ° C to + 300 ° C. Even if aerogel fibers are processed and made into cold-proof clothing, they can still provide warmth in extremely cold temperatures.
     Meanwhile, the extremely high thermal insulation, moisture absorption and breathability of aerogel fibers are also very suitable for application in products such as thermal underwear. The biggest problem with ordinary thermal underwear is that it keeps warm but is not breathable. When people move from outdoors to indoors in winter and the temperature rises, the moisture produced by the human body is difficult to be discharged, which significantly reduces the comfort of the user's wear. However, the above problems can be perfectly solved by using aerogel fibers.
     Aerogel fibers have a wide range of applications. Besides outdoor clothing and thermal underwear, they can also be used in bulletproof vests, tents, sleeping bags, knee pads, yoga wear and other fields.
     At present, the application of aerogel fibers in the textile and garment market is still mainly concentrated on winter cold-proof and warm-keeping products. Traditionally, this clothing niche market has mostly been dominated by cotton, down, as well as products such as wool, cashmere, and acrylic.
     Industry insiders all know that the thermal insulation performance of fiber materials is directly proportional to the content of still air inside the fiber material, inversely proportional to the diameter of the fiber, and inversely proportional to the overall density of the material. Aerogel fibers have an extremely high porosity and a relatively high specific surface area. Therefore, theoretically, they are currently the best type of fiber material for heat insulation and preservation in the textile and garment industry. So much so that aerogel fibers may also be a direction for the development of thermal insulation fibers in the future.
