Particles are bound to fibrous materials by a non-polymeric binder selected from the group consisting of an alcohol, a carboxylic acid, an aldehyde, an amino acid, an amide, and a polyamine. Particular disclosed binders include glycerin, glyoxal, ascorbic acid, urea, glycine, pentaerythritol, a monosaccharide and a disaccharide. The fibrous material is preferably cellulose fibers, and the particles are preferably superabsorbent particles. Fibers that incorporate the particles and binder preferably include 3-80% binder and 0.05-80% particles, by weight of the total weight of the fibrous material, binder and particles. Particles adhered to the fibers with the binder are firmly adhered and are not easily dislodged, hence products incorporating the fibers retain the desired property imparted by the particles, such as absorbency. Fibrous products produced by this method include fibers to which particles are bound, and fibers which have been treated with the binder but to which particles are not bound.

A product comprising: individualized fibers having a hydrogen bonding functionality; particles having a hydrogen bonding or a coordinate covalent bonding functionality; and a non-polymeric organic binder having a volatility less than water, the binder having a functional group capable of forming hydrogen bonds or coordinate covalent bonds with the particles, and a functional group capable of forming hydrogen bonds with the fibers, wherein the binder has formed hydrogen bonds with the fibers and a hydrogen bond or coordinate covalent bond with the particles, and wherein the particles are insoluble in the binder, such that a substantial portion of the particles that are bound to the fibers are adhered in particulate form to the fibers by non-covalent bonds.
