Abstract
A method of producing easily densified high bulk fibers that have adhered particulates. The high bulk fibers have hydrogen bonding or coordinate covalent bonding functionalities, and a binder is applied to the fibers to bind the particles to the fibers. The binder has a functional group that forms a hydrogen bond or a coordinate covalent bond with the particles, and a functional group that forms a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers are adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder is in turn adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.
