Abstract
A method of manufacturing an article at least partially made of cellulose fibers comprises inserting a cellulose pulp comprising cellulose fibers and water into a mixing cavity; applying a high shear mixing action to the cellulose pulp using a high-shear mixer, such that a foam blend comprising cellulose fibers, water and air bubbles is created; inserting the foam blend into a mold cavity; and molding the article by heating the foam blend contained within the mold cavity.
Claims16
A method for manufacturing an article at least partially made of cellulose fibers, the method comprising the following steps:
- a. inserting a cellulose pulp comprising cellulose fibers and water into a mixing cavity (24);
- b. applying a high shear mixing action to the cellulose pulp using a high-shear mixer, such that a foam blend comprising cellulose fibers, water and air bubbles is created;
- c. inserting the foam blend into a mold cavity;
- and
- d. molding the article by heating the foam blend contained within the mold cavity.
An article at least partially made of cellulose fibers, comprising an inner core portion and an outer skin portion, wherein the density of the material formed by the cellulose fibers in the inner core portion is lower than the density of the material formed by the cellulose fibers in the outer skin portion.
