A METHOD FOR PRODUCING A CELLULOSE PRODUCT
20210069942 · 2021-03-11 ·

A method for producing a cellulose product from a multi-layer cellulose blank structure, wherein the method comprises the steps; forming the multi-layer cellulose blank structure from at least a first layer of dry-formed cellulose fibres and a second layer of a cellulose fibre web structure, through arranging the at least first layer and second layer in a superimposed relationship to each other and in the superimposed relationship arranging the at least first layer and second layer in contact with each other; arranging the multi-layer cellulose blank structure in a forming mould; heating the multi-layer cellulose blank structure to a forming temperature in the range of 100 C. to 300 C., and forming the cellulose product from the multi-layer cellulose blank structure in the forming mould, by pressing the heated multi-layer cellulose blank structure with an isostatic forming pressure of at least 1 MPa, preferably 4-20 MPa, wherein the multi-layer cellulose blank structure is shaped into a two-dimensional or three-dimensional fibre composite structure having a single-layer configuration.

LIGNOCELLULOSIC COMPOSITES PREPARED WITH AQUEOUS ALKALINE AND UREA SOLUTIONS IN COLD TEMPERATURES SYSTEMS
20210207320 · 2021-07-08 ·

Unique, inexpensive, and strong biocomposites are obtained from blending cellulose matrix materials pith 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 d 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).
