Patent number: 11970817Abstract: A method for preparing an aqueous suspension may include providing a fibrous substrate comprising cellulose having a Canadian Standard freeness equal to or less than 450 cm3, and microfibrillating the fibrous substrate in an aqueous environment by grinding in the presence of a grinding medium consisting essentially of mullite. The grinding may be carried out in the absence of grindable inorganic particulate material. The grinding medium may be present in an amount of at least about 10% by volume of the aqueous environment. The microfibrillated cellulose may have a fibre steepness of from about 20 to about 50.Type: GrantFiled: May 27, 2022Date of Patent: April 30, 2024Assignee: FIBERLEAN TECHNOLOGIES LIMITEDInventors: John Claude Husband, Per Svending, David Robert Skuse, Tafadzwa Motsi, Mikko Likitalo, Alan Coles

Publication number: 20240133123Abstract: The present invention is directed to products, such as paper and paperboard products, comprising a substrate containing a recycled cellulose-containing material and top ply comprising one or more inorganic particulate material; to methods of making such paper and paperboard products, and associated uses of such paper and paperboard products. The microfibrillated cellulose and inorganic particulate material are applied at a stage when the substrate comprising a wet web of pulp is in the process of being formed on the wire of a papermaking machine, thereby avoiding the additional cost of more extensive equipment and machinery as well as in separate drying of a coating. The microfibrillated cellulose facilitates the application of inorganic particulate onto the surface of a wet paper or paperboard substrate.Type: ApplicationFiled: November 7, 2023Publication date: April 25, 2024Applicant: FIBERLEAN TECHNOLOGIES LIMITEDInventors: Per SVENDING, Jonathan Stuart PHIPPS, Tom REEVE-LARSON, Tania SELINA, David SKUSE
