ABSORBING CELLULOSE WEB OF REGENERATED CELLULOSE MICROFIBRES AND METHOD OF ITS PRODUCTION Russian patent published in 2011 - IPC D21H13/08 D21H21/22 A47K10/02 A47K10/16 A61F13/15 A61L15/16 

FIELD: textile, paper.

SUBSTANCE: absorbing cellulose web is designed for fabrics or towels and contains cellulose paper-forming fibres and fibrillated regenerated cellulose microfibres at their specified ratio. Fibrillated fibres represent cellulose regenerated from a solution. A dissolvent is an N-oxide of tertiary amine or an ionic liquid. Fibrillation of a microfibre is controlled so that the fibre has lower granularity and reduced beating rate compared to non-fibrillated regenerated cellulose microfibre. Microfibre has CSF-value of beating rate below 100 ml., weighted average diameter is less than 1 micron, weighted average length is below 400 micron, and fibre density is more than 2 billion fibres/gramme. There is also a method proposed to produce an absorbing cellulose web.

EFFECT: simultaneous improvement of softness and CD-extensibility in wet condition at lower module at the specified tensile strength, improved draping, increased absorbing ability.
