Preparation of novel chitosan derivatives and applications in functional finishing of textiles

A novel chitosan derivative, O-acrylamidomethyl-N-[(2-hydroxy-3- dimethyldodecylammonium) propyl] chitosan chloride (NMA-HDCC), was synthesized by reacting chitosan (CTS) with epoxypropyl dodecyl dimethyl quaternary ammonium salt and N-methylolacryl amide (NMA). The chemical structure of the quaternized chitosan was analyzed by FTIR and NMR. The water soluble derivative can form covalent bonding with cellulosic fibers and bring quaternary salt...
