Composite fibrous structures for absorption of liquids

摘要

A composite fibrous structure which absorbs liquids is in the form of a yarn or nonwoven fabric which is coated with a superabsorbent polymer in an amount of up to 500 % SAP add-on. The yarn or nonwoven fabric is made of fibers having a non-round cross section. The fibers when in the form of a filament yarn have a specific volume of the filament yarn being greater than or equal to 1.50 cc/gm.
