    Abstract: The present invention is a method for forming a fibrous molded article that includes providing a aqueous slurry containing a plurality of fibers, providing the slurry into a dehydration chamber to remove at least some of the amount of water from the slurry to achieve an intermediate form, removing the fibrous intermediate form from the dehydration chamber and placing the fibrous intermediate form in a press having a first mold portion and a second mold portion wherein at least one of the first or second mold portions includes a contour, applying at least one of heat and pressure to the press such that at least fiber to fiber bonding or chemical cross-linking of fibers occurs, and removing the three-dimensional solid fibrous molded part from the press.

    Abstract: The present invention is directed to a shaped soft goods article that is unitary non-woven material having at least one three-dimensional shape. The article includes a first region substantially formed of a first formula and a second region substantially formed of a second formula. Between the first and second regions, there is an intermingling region that includes at least some of the first formula and the second formula. The first and second formulas are both comprised of at least one type of natural or synthetic fibers and at least one of crosslinkers, natural and/or synthetic adhesives, biobased and/or synthetic thermoplastics, including nanocellulose, and/or latex; however, the first and second formulas differ in at least one characteristic. An intermingling region exists where the first region (and first formula) intermingle with the second region (and second formula) meet.

    Abstract: The present invention discloses a method and apparatus for molding a fibrous molded article. An aqueous slurry that contains an amount of water and a plurality of fibers is added to the molding apparatus. First and second molding screens are positioned on a first pressing unit and a second pressing unit, respectively, and include a plurality of openings. The first and second molding screens can include secondary relief features. A pressing chamber sleeve slidably engages with the first pressing unit and the second pressing unit to ensure proper alignment during molding operation. The first and second molding screens at least partially form a void that is intended to receive an amount of the aqueous slurry. The apparatus includes a heat and pressure source that removes at least some of the water from the aqueous slurry and bonds the fibers to one another resulting in the fibrous molded article.
