CELLULOSE STAPLE FIBRE, ITS APPLICATION AND FILLER Russian patent published in 2010 - IPC D01F2/06 D01D5/253 D01D5/26 B68G1/00 D01F2/10 

FIELD: machine building.

SUBSTANCE: cellulose staple fibres in cross section have three or more blades; also linear density of fibre is from 1.0 to 3.10 dtex, preferably more, than 3.10 dtex, preferably, over 5.10 dtex, and most preferably from 5.6 dtex up to 10 dtex, particularly over 6.10 dtex, and especially from 6.3 to 10 dtex. Module of fibre in wet condition corresponds to a formula: module of fibre in wet condition is (cN)≥0.5*√T, where T is linear density of fibre in dtex; rupture strength corresponds to formula: rupture strength of fibre (cN)≥1.3*√T+2*Tb, where T is linear density of fibre in dtex.

EFFECT: multitude of said fibres as filler possesses high moisture absorption at low density and big volume.
