Extreme soft material, without any damage to the surface, even in high-precision fields, such as coated lens, a large scale integrated circuit production process can also be assured that use. Excellent and high-density weaving structure make the specific surface area for the per gram of microfiber cleaning cloth reaches 200m2, dust absorption rapidly increase several times, only need to wipe slightly then will be able to completely clean the surface. Ultra-fine fibers, the excellent capillary effect, fast dry as it was one of the notable characteristics.
