Embodiment 1
[0060] Modified cellulose fibers:
[0061] The modified cellulose fiber is modified by the cellulose fiber through the small molecule quaternary ammonium salt cationic modifier and the high molecular quaternary ammonium salt cationic modifier as the cationic modifier, and the obtained pH value is 6.5 When -8.5, the Zeta electrode potential value is the modified cellulose fiber of 0-15mV; The described small molecular quaternary ammonium salt cationic modifier is a chlorotriazine type quaternary ammonium salt compound, and the described polymer quaternary ammonium salt The cationic modifier is polyepichlorohydrin dimethylamine.
[0062] The above is the modified cellulose fiber of the present invention. Due to the small molecular weight of the small molecular quaternary ammonium salt cationic modifier, it can not only be adsorbed on the surface of the fiber but also diffuse into the fiber, while the high molecular weight quaternary ammonium salt cationic modifier has a large m...
