MAN-MADE CELLULOSIC FIBRE AND NONWOVEN PRODUCT OR FABRIC COMPRISING THE CELLULOSIC FIBRE

The present invention relates to a modified cellulosic fibre that comprises anionic moieties in an amount of more than 0.25mol/kg of dry fibre and has applied theron a polymeric modifying agent in an amount of from 0.5 wt.% to 5.0 wt.%， based on dry fibre， the polymeric modifying agent comprising cationic moieties with a charge of at least 1.5meq per gram of polymer and the molar ratio of anionic moieties to cationic moieties contained in the fibre is in the range of from 1:1 to 25:1. The fibre according to the present invention is characterized in that the anionic moieties are incorporated in the fibre and are from carboxymethylcellulose， and that the polymeric modifying agent comprising cationic moieties is selected from the group consisting of polydiallyldimethylammonium chloride (poly-DADMAC)， poly(acrylamide-co- diallyldimethylammonium chloride) (PAM-DADMAC) and mixtures thereof. The invention furthermore relates to a nonwoven product or fabric comprising the modified cellulosic fibre.
