CELLULOSE FIBRES WITH IMPROVED SURFACE, METHODS FOR PRODUCTION OF CELLULOSE FIBRES WITH IMPROVED SURFACE, PRODUCTS CONTAINING CELLULOSE FIBRES WITH IMPROVED SURFACE, AND METHODS FOR PRODUCTION OF SUCH PRODUCTS Russian patent published in 2019 - IPC D21C9/00 

FIELD: textile.

SUBSTANCE: various versions of the present invention refer to cellulose fibres with improved surface, to various products containing cellulose fibres with improved surface, and to methods and systems for production of cellulose fibres with improved surface. Cellulose fibres with an improved surface can be introduced into a series of products which can benefit from such properties, including, for example, paper products, paper cardboard products, fibrous cement boards, fibre-reinforced plastics, fluff pulps, hydrogels, cellulose acetate products and carboxymethyl cellulose products. In some embodiments, a plurality of cellulose fibres with an improved surface have a linear weighted average length of the fibres of at least about 0.3 mm and an average hydrodynamic specific surface area, at least about 10 m²/g, where the number of cellulose fibres with improved surface is at least 12,000 fibres/mg in terms of dry substance (drying in furnace).

EFFECT: different versions of cellulose fibres with improved surface have considerably increased surface area compared to traditional refined fibres with preferential minimization of length reduction after refining.
