Patent number: 11970823Abstract: A process for forming a pre-form for a moulded pulp fibre product involves providing a porous mould that has one or more pre-form mould portions that each have an outer surface corresponding to a surface of the pre-form. Pulp fibre slurry is discharged from an outlet; each pre-form mould portion is coated with discharged pulp fibre slurry by moving the porous mould relative to the outlet. Thus, a slurry deposit for the pre-form is formed on the outer surfaces of the pre-form mould portions. Fluid from the slurry deposit is extracted through the porous mould to form the pre-form.Type: GrantFiled: January 23, 2020Date of Patent: April 30, 2024Assignee: VARDEN PROCESS PTY LTDInventors: Mark Appleford, Stuart Gordon

Patent number: 11970819Abstract: The present disclosure relates to tissue products comprising crosslinked fibers. The tissue products generally have good formation, such as a Formation Index greater than about 20, strength, such as geometric mean tensile strengths greater than about 700 g/3? and high bulk, such as sheet bulks greater than about 10 cc/g. Unlike many prior art crosslinked fibers, the crosslinked softwood pulps of the present invention, which are preferably prepared using a glyoxal based crosslinking reagent, are readily dispersible in water and have relatively low degrees of kink and curl. As such, the fibers are well suited for forming wet-laid tissue products and more particularly wet-laid tissue products having improved physical properties, such as improved bulk.Type: GrantFiled: January 20, 2021Date of Patent: April 30, 2024Inventors: Stephen M.
