DECREASING FIBER DENSITY IN WET PARTS FORMED FROM SLURRIES
20240200279 · 2024-06-20 ·

According to examples, a wet part composed of fibers may be removed from a slurry of the fibers on a forming screen having pores, the wet part having a first surface in contact with the forming screen. A second surface of the wet part may be pulled away from the first surface of the wet part while a suction force is applied onto the first surface through the pores in the forming screen to cause a density at which the fibers are arranged in the wet part to be decreased. In addition, following a predefined length of time after initiation of the pulling of the second surface away from the first surface, the wet part may be removed from the forming screen, in which an article formed from the wet part is to function as a filter following the wet part being dried.

METHOD FOR MANUFACTURING CELLULOSE PRODUCTS AND A PRODUCT FORMING UNIT FOR MANUFACTURING CELLULOSE PRODUCTS
20240183112 · 2024-06-06 ·

A method for manufacturing non-flat cellulose products from an air-formed cellulose blank structure in a product forming unit. The product forming unit includes a buffering module and a pressing module including one or more forming molds. The method includes providing the cellulose blank structure and feeding the cellulose blank structure to the buffering module; buffering the cellulose blank structure in the buffering module, and feeding the cellulose blank structure from the buffering module to the pressing module; forming cellulose products from the cellulose blank structure in the one or more forming molds by heating the cellulose blank structure to a forming temperature, and pressing the cellulose blank structure with a forming pressure. The cellulose blank structure is continuously fed to the buffering module in a first feeding direction, and intermittently fed from the buffering module in a second feeding direction, wherein the second feeding direction differs from the first feeding direction.

LIGNOCELLULOSIC COMPOSITES PREPARED WITH AQUEOUS ALKALINE AND UREA SOLUTIONS IN COLD TEMPERATURES SYSTEMS AND METHODS
20190119851 · 2019-04-25 ·

Unique, inexpensive, and strong biocomposites are obtained from blending cellulose matrix materials with lignocellulosic reinforcement materials with the aid of alkaline aqueous solvent and cold temperatures. These lignocellulosic composites (LCs) are produced without use of any thermoplastic resins, adhesives, catalysts, plasticizers or complicated chemical or physical procedures. The LCs include a matrix and a reinforcement material. The matrix is a cellulose material (e.g., cotton, hemp, flax, or wood) that is liquefied using an aqueous alkaline solvent solution under cold temperatures to more readily adhere and/or incorporate/encapsulate the lignocellulosic reinforcements (wood chips, fibers, and other lignocellulosic sources).
