초록 ▼

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.

대표청구항 ▼

A method of producing fibers with adhered particles comprising: providing fibers that have hydrogen bonding functional sites; adding particles to the fibers, wherein the particles have a hydrogen bonding or coordinate covalent bonding functionality; interposing a binder having a functional group capable of forming a binder-fiber hydrogen bond as well as a functional group capable of forming a binder-particle hydrogen bond or a binder-particle coordinate covalent bond between fibers having hydrogen bonding functional sites and particles having a hydrogen bonding or coordinate covalent bonding functionality, the binder selected from the group consisting of (a) a polymeric binder with repeating units, wherein each repeating unit has a functional group capable of forming a hydrogen bond or a coordinate covalent bond with the particles, or a hydrogen bond with the fibers, and (b) a nonpolymeric organic binder, whereby a substantial portion of the particles with said functional groups are bound in particulate form to the fibers primarily by a hydrogen bond or coordinate covalent bond; and thereafter densifying the fibers with their bound particles by applying external pressure to the fibers. A fiber product comprising: individualized fibers densified by applying pressure, having a density of 0.1 to 0.7 g/cc, and hydrogen bonding functionalities; and particles that are bound to the fibers by a binder interposed between the particles and the fibers, the particles having a hydrogen bonding or coordinate covalent bonding functionality, and the binder having a functional group capable of forming a binder-particle hydrogen bond or a binder-particle coordinate covalent bone and a functional group capable of forming a binder-fiber hydrogen bond, the binder selected from the group consisting of (a) a polymeric binder with repeating units, wherein each repeating unit has a functional group capable of forming a hydrogen bond or a coordinate covalent bond with the particles, or a hydrogen bond with the fibers; and (b) a nonpolymeric organic binder, wherein the product comprises 0.05-80% of said bound particles, said bound particles bound to the fibers primarily by a hydrogen bond or coordinate covalent bond.
