The definition of microfiber varies, also known as microfiber, fine fiber,minuteness fiber. Generally, the fiber with a fineness of 0.3 denier (5 microns in diameter) is called ultrafine fiber. Foreign countries have produced 0.00009 denar of ultra-fine wire, if such a wire from the earth to the moon, its weight will not exceed 5 grams. China has been able to produce 0.13-0.3 dener of ultrafine fiber. The main ingredients of microfiber are polyester and polyemide (generally, it is polyester 80% polyester 20% and polyester 100%)
Because the fiber is very fine, greatly reduces the stiffness of the silk, and makes the fabric feel soft. Fine fiber can also increase the layered structure of the silk, increase the specific surface area and capillary effect, so that the reflected light inside the fiber is more delicate in the surface distribution, so that it has the elegant luster like silk, and has a good moisture absorption and dispersion. With the superfine fiber clothing, comfortable, beautiful, warm, breathable, good drapability and fullness, the hydrophobic and antifouling sex has obviously improved, large specific surface area and soft can be used to design different organizational structure to make it more absorbing sunlight or faster heat loss temperature is warm in winter and cool in summer.
