In addition to softness, an important characteristic of powder puffs is their intake ability, i.e., the ability to hold powder. It was reported that for synthetic fibers important factors in designing high-intake powder puffs are mostly geometric ones: fiber diameter, pile length, and space between fibers, with little dependence on material factors."Intake Ability of Powder Puffs Made of Synthetic-fiber Cloths" , Journal of the Japan Research Association for Textile End-Uses (2005), vol. 46, no. 8. 519-528.
