FABRIC-CREPED ABSORPTION SHEET WITH VARIABLE LOCAL BASIC WEIGHT Russian patent published in 2011 - IPC B31F1/12 D21F11/14 

FIELD: textile, paper.

SUBSTANCE: absorbing cellulose sheet has a variable local basic weight and contains a paper-fibre mesh made of multiple extended compact areas and multiple fibre-rich top areas. At the same time the extended compact areas are made of pressed paper fibres. Besides, the pressed fibres are aligned in general in a machine direction of the sheet and have a relatively low local basic weight, and also front and back edges at their longitudinal ends. And enriched fibres of top areas are connected to multiple extended compact areas. Besides, the top areas have relatively high local basic weight and multiple collars passing across the machine direction of the collars, having vault-like profiles relative to the front and rear edges of multiple extended compact areas. Invention also relates to a method to make such a sheet.

EFFECT: group of inventions ensures production of an absorbing sheet, having improved qualities, such as volume, softness and rupture strength, using repeatedly used fibres as a material.
