Definition:Microfiber is a synthetic material composed of extremely fine fibers (single filament diameter ≤ 0.3 denier, approximately 1/200 of a human hair), typically made from a composite of polyester (PET) and polyamide (PA). Its high-density fiber structure endows it with strong adsorption ability and soft touch.characteristic:High specific surface area: The fibers are extremely fine, with a large number of fibers per unit area and strong adsorption force.Dust free shedding: No cotton residue, suitable for precise cleaning.Hydrophobic and Oleophilic (some types): can adsorb oil and small particles, with high cleaning efficiency
