A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

1. A method of binding particles to wood pulp fibers with a binder, comprising the steps of:providing fibrous material comprising a wood pulp fiber having a hydrogen bonding functionality; providing particles different in composition from the fiber and having a hydrogen bonding or a coordinate covalent bond forming functionality; selecting a non-polymeric organic binder, or non-reactive combinations thereof, the binder comprising binder molecules, the binder molecules having at least one functional group capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group capable of forming a hydrogen bond with the fiber; wherein the non-polymeric organic binder is selected from the group consisting of glycerin, a glycerin monoester, a glycerin diester, glyoxal, ascorbic acid, lactic acid, urea, glycine, pentaerythritol, a monosaccharide, a disaccharide, taurine, dipropylene glycol, propylene glycol, butylene glycol, trimethylene glycol, ethylene glycol, a urea derivative, and combinations thereof; exposing the particles to sufficient amounts of the binder to at least partially coat the particles with the binder in an amount ranging from 0.03 to 5 percent by weight based on the particles; contacting the at least partially binder coated particles with the fiber; and binding the particles to the fiber at a temperature below 100.degree. C. by forming hydrogen or coordinate covalent bonds between the binder and the particles and forming hydrogen bonds between the binder and the fiber.
