Abstract
A light weight, low density absorbent structure suitable for use in disposable absorbent products which is formed from a fibrous web of cellulose and cellulose acetate fibers. The fibrous web is treated with a triacetin solvent and heat cured to bond the fibers. The absorbent structure has excellent structural integrity and an absorbent capacity and strength which is equal to or exceeds that of absorbent structures having twice the basis weight.
