CELLULOSE FIBERS WITH IMPROVED SURFACE, METHODS OF PRODUCING CELLULOSE FIBERS WITH IMPROVED SURFACE, PRODUCTS CONTAINING CELLULOSE FIBERS WITH IMPROVED SURFACE, AND WAYS OF OBTAINING SUCH PRODUCTS Russian patent published in 2018 - IPC D21C9/00 

FIELD: textile.

SUBSTANCE: various embodiments of the present invention relate to cellulosic fibers with an improved surface, to various products containing cellulose fibers with an improved surface, and methods and systems for producing cellulosic fibers with an improved surface. Various embodiments of the improved surface cellulosic fibers have a significantly increased surface area as compared to conventional refined fibers, with the advantage of minimizing the reduction in length after refining. In some embodiments, a plurality of improved surface cellulosic fibers have a linear weight average fiber length of at least about 0.3 mm and an average hydrodynamic specific surface area of at least about 10 m²/g, where the number of cellulose fibers with an improved surface is at least 12,000 fibers/mg in terms of dry matter (oven drying).

EFFECT: cellulosic fibers with an improved surface can be introduced into a series of products that can gain from such properties, including, for example, paper products, paper board products, fiber cement slabs, fiber reinforced plastics, fluff pulps, hydrogels, cellulose acetate products and carboxymethylcellulose products.
