OPTIMIZED AMOUNT OF HEMICELLULOSE IN NON-WOOD FIBERS FOR PAPER-BASED PRODUCTS Russian patent published in 2021 - IPC D21H11/12 D21H11/16 D21H27/00 

FIELD: paper industry.

SUBSTANCE: invention relates to the use of non-wood natural fibers in paper-based products. A method for making a paper-based sheet includes dispersing soft wood fibers in water and dispersing processed non-wood fibers to form the first and the second fiber suspensions, dispersing the specified fiber suspensions on a forming mesh to form a wet paper-based canvas. Next, the wet canvas is dehydrated and dried. Processed non-wood fibers are obtained from plants from the bluegrass family, they contain less than 15 percent of hemicellulose and have drainage rate according to the Canadian standard (CSF) of more than 350 ml.

EFFECT: increase in softness of obtained paper-based products is achieved.
