METHOD FOR MANUFACTURING A FIBROUS WEB
20210189646 · 2021-06-24 · ·

A method for manufacturing a fibrous web, such as web of paper, board, tissue or the like is disclosed. The method includes obtaining at least one fibre suspension of lignocellulosic and/or cellulosic fibres and feeding the fibre suspension into an intermediate residence entity. The fibre suspension including bacterial endospores, is discharged out of the intermediate residence entity via an outlet after a residence time of at least 2 hours in the intermediate residence entity and after a time delay the fibre suspension is formed into a fibrous web. Bacterial endospores are sensitized by adding a germinant surfactant including a primary or secondary ammonium head group and a linear unsubstituted C12-alkyl tail, to the fibre suspension at an addition point located at a lower part of the intermediate residence entity or after the outlet of the intermediate residence entity, but before the formation of the fibrous web.

System and methods for reducing edge wicking of a paperboard comprising fruit fiber and compositions produced thereby

A composition including a first fiber derived from a first natural source, and a second fiber derived from a fruit, the second fiber being substantially free of surface active components. Surface active components may include oils, fatty acids, or other aliphatic and aromatic moieties that compromise edge wick performance. A process of manufacturing a paperboard product may include removing surface active components from fruit fiber to be included in manufacturing paper products to obtain a paper product with improved edge wicking properties.
