ABSORBENT MATERIAL is a term used to describe materials that can absorb liquids, such as water or oil. SWAB, SPONGE, and TERRY are all examples of absorbent materials. A SWAB is a small piece of absorbent material, usually made of cotton, that is used for cleaning or applying medication. A SPONGE is a porous material made from natural or synthetic fibers that can absorb liquids. Terry is a type of fabric with a looped pile on one side, which makes it highly absorbent.
