What material is air-conditioning fiber? What is the function of air conditioning fiber? Air conditioning fiber technology was developed by NASA for the moon landing program. The purpose was to make lunar landing clothing for astronauts, including gloves, socks, underwear, etc., and later developed into general clothing, especially outdoor clothing, including ski shirts, pants, sweaters, etc.
Air-conditioning fiber is a new type of “smart” fiber that was successfully developed in 1988 and is now widely used in fashion and bedding.
Use of air-conditioning fiber:
Air-conditioning fiber technology is mainly used in acrylic fiber, with specifications of 2.2dex, 3.3dex and 5dex, with lengths ranging from 51mm to 60~110mm. It is available for loose fibers and tops.
Production principle:
The principle of air conditioning fiber: using the heat absorption and heat release functions generated by the phase change of objects, for example When water turns into water vapor, it will definitely absorb heat, which we call a phase change reaction. For example, air-conditioning fibers such as Outlast used by American aerospace technology and Onwent from China use solid-liquid transition to achieve heat absorption and release. The function is to implant PCM (nano-microcapsules) into the fiber during the production process of the fiber. When the temperature reaches a certain value, the capsule undergoes a physical transformation (solid-liquid) to achieve endothermic and exothermic functions. Function.
