Abstract (en)
[origin: WO9011171A1] Discontinuous natural fibers have a coating of a thermoplastic binder. A substantial majority of the fibers and any fiber bundles are unbonded to one another by the thermoplastic binder material. One or more solid particulate materials may be adhered to the fibers by the binder material. The binder material is heat fusible and the coated fibers can be mixed with other fibers for subsequent heat bonding and used in producing a wide variety of products.
