Ultrafine fibers, also known as microfibers, fine denier fibers, very fine fibers, English name microfibers. The main components are polyester and polyamide.In general, the size (i.e. thickness) of chemical fibers is between 1.11 and 15 denier, and the diameter is about 10 to 50 microns, Ultrafine fibers are usually said to be between 0.1 and 0.5 denier in size and less than 5 microns in diameter. Their fineness is 1/200 of that of hair, 1/20 of that of ordinary chemical fibers, and their strength is five times that of ordinary fibers (durability), adsorption capacity, water absorption speed and water absorption capacity are seven times that of ordinary fibers.
Ultrafine fibers are smaller than natural silk, weighing only 0.03 grams per kilometer. They do not contain any chemical constituents. The greatest feature of Ultrafine fabrics is that there are many micro-voids between the micro-fibers, thus forming capillary structure, which can be processed into towel-like fabrics with high water absorption. Washed hair can be quickly absorbed by Ultrafine Fiber Towel. Make hair dry quickly, superfine fiber towel has super absorbency, fast absorbency, more absorbency and so on, It can carry more than 7 times its own weight of water, absorb water 7 times as much as ordinary fibers, absorb water 7 times as fast as ordinary towels, and fiber strength 5 times as ordinary fibers (durability), so the water absorption of ultra-fine fibers towels is far superior to other fabrics.
Ultra-fine fibers have capillary structure and large surface contact area, so the coverage of super-fine fibers is very high. The surface of super-fine fibers contacts with dust or oil more frequently, and oil and dust penetrate through the gap between super-fine fibers more often. Therefore, super-fine fibers have a very strong function of decontamination and cleaning. Ultra-fine fibers towels can penetrate deep into skin pores. Effective removal of dirt, grease, dead skin, cosmetic residues on the body surface to achieve cosmetic, body and cleansing effect.
Ultrafine fibers have very small diameter, so their bending strength is very small, and their hand feel is very soft. The seam between them is between the diameter of water droplets and the diameter of water vapor droplets. Therefore, ultra-fine fibers fabrics have the effect of waterproof and air permeability, and can overcome the shortcomings of natural fibers, such as wrinkle-prone, artificial fibers impermeable and so on. Their durability is more than five times that of ordinary fabrics. They are processed with ultra-fine fibers. Bath towel, skirt, bathrobe, human body wear more soft, comfortable, care for the delicate skin of the human body.
Ultrafine fibers are not only used in people's home life, but also widely used in automobile maintenance, sanitarium hotel, hairdressing, sporting goods, daily necessities and other industries.
