Microfiber components mainly consist of polyester and polyamide. Generally, the denier of chemical fibers is between 1.11 and 15 denier, and the diameter is about 10-50 micrometers. The microfibers we usually talk about are between 0.1 and 0.5 denier, and the diameter is less than 5 micrometers. The fiber fineness is the hair filaments. The 1/200 of it is 1/20 of that of ordinary chemical fiber, its fiber strength is 5 times that of ordinary fiber (durability), and its adsorption capacity, water absorption speed and water absorption capacity are 7 times that of ordinary fiber. Microfiber towels were used in the car wash industry.
