Chitosan-Coated Fibers for Use in Papermaking

Abstract

Chitosan was precipitated onto wood pulp, glass and polypropylene fibers suitable for papermaking. The coating which formed on the fibers was characterized by photomicrography after the formation of colored derivatives, and by scanning electron microscopy. The most uniform and adherent coatings were formed on the wood pulp fibers and the least were formed on the polypropylene fibers. Paper handsheets were readily formed from the chitosan-coated wood pulp and glass fibers, but not from the chitosan-coated polypropylene fibers.

Chitosan‐coated paper: Effects of nisin and different acids on the antimicrobial activity

“…Cationic chitosan acetate blends with poly(vinyl alcohol) and gelated starch have been used as fillers for paper 32. Chitosan has also been precipitated onto wood pulp and glass fibers to be formed into paper sheets 33…”

A Review on the Use of Chitosan and its Derivatives as Radical Scavenger and Metal Ions Chelating Agent

“…The interest in using chitosan and its derivatives as interaction polymers for cellulose arises from two facts: (a) chitosan is a polysaccharide second by the prevalence in nature after cellulose; (b) chitosan has similar chemical structures as cellulose, providing the possibility of producing a homogeneous blend that combine the unique properties of chitosan and the good availability of cellulose. Numerous studies have showed that chitosan and its derivatives have potential to improve both the strength and the printing properties of papers based on wood fiber [19][20][21][22]. The closure of water circulations in the preparation of high yield pulps would cause concentration of metal ions problems in the processes.…”
