| titleOfInvention | A process for preparing cationic regenerated cellulosic fibers |
| abstract | A process for continuous production of a cationic regenerated cellulosic fiber is disclosed. Said process comprises the steps of: (a) providing a wet regenerated cellulosic fiber; (b) treating said regenerated cellulosic fiber with an alkaline solution of 3-halo-2- hydroxyalkyl-N,N,N-tri-alkyl or aryl substituted ammonium compound having the general formula I, or a salt thereof while maintaining a pH of around 9-13 (Formula I) X wherein X is a halogen selected from a group consisting of chloride and bromide; R1, R2, R3, are individually selected from a group consisting of C1-C4 alkyl, benzyl and substituted benzyl groups; and R4 is hydrogen; (c) subjecting the treated regenerated cellulosic fiber to a moisture regulating step such that the moisture content in the treated cellulosic fiber is not more than 120% of weight of the treated cellulosic fiber; and (d) curing the treated cellulosic fiber at a temperature ranging between 100° C and 145° C, to obtain regenerated cellulosic fiber which is cationically modified by 3-halo-2- hydroxyalkyl-N,N,N-tri-alkyl or aryl substituted ammonium compound having formula I, or a salt thereof in an amount ranging between 1.5 to 33 % by weight. |
