The present invention relates to a modified cellulosic fiber that comprises anionic moieties in an amount of more than 0.25 mol/kg of dry fiber and has applied thereon a polymeric modifying agent in an amount of from 0.5 wt. % to 5.0 wt. %, based on dry fiber, the polymeric modifying agent comprising cationic moieties with a charge of at least 1.5 meq per gram of polymer and the molar ratio of anionic moieties to cationic moieties contained in the fiber is in the range of from 1:1 to 25:1. The fiber according to the present invention is characterized in that the anionic moieties are incorporated in the fiber 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 fiber.

Man-made cellulosic fiber and nonwoven product or fabric comprising the cellulosic fiber

The present invention relates to a dispersible non-woven fabric, a method for producing a dispersible non-woven fabric and a wipe or tissue. The dispersible non-woven fabric comprises natural pulp fibers in an amount of from 70 to 90 wt.-% based on the total weight of the non-woven fabric and cellulosic fibers in an amount of from 10 to 30 wt.-% based on the total weight of the non-woven fabric. At least a part of the pulp fibers and of the cellulosic fibers are entangled with each other. At least 20% of the natural pulp fibers have a fiber coarseness of from 1.0 to 2.0 dtex.

Dispersible non-woven fabric and method for producing the same

The present invention relates to a paper or non-woven web, comprising fibers and at least one crosslinking or functionalization agent selected from the group consisting of carboxylic acids, halogenated heteroaromatic compounds and salts thereof, wherein said at least one crosslinking or functionalization agent has a molecular weight of not more than 1000 g/mol, and wherein at least a part of said crosslinking or functionalization agent is bound to said fibers, a process for producing said paper or non-woven web, and the use of said crosslinking or functionalization agent in a paper or non-woven web.
