Abstract: Micro fibers and light-weighted fabric have become dominant in thermal material production. Kapok fiber is so far a natural fiber with the highest hollowness and the lowest specific mass that any micro chemical fiber is incomparable. The unique hollow structure of kapok fiber has enlarged the specific surface area of the fiber, endows the fiber with outstanding moisture transfer property and makes it an ideal environment-friendly natural thermal fiber.
Key words: thermal fiber; kapok; environment-friendly; hollow fiber.
