Embodiment 1
[0060] Modified cellulose fibers:
[0061] A cationically modified modified cellulose fiber, the modified cellulose fiber is made of cellulose fiber through a small molecular quaternary ammonium salt cationic modifier and a polymer quaternary ammonium salt cationic modifier as cationic modification agent, carry out modification treatment, when the obtained pH value is 6.5-8.5, the modified cellulose fiber whose Zeta electrode potential value is -5~15mV; the described small molecule quaternary ammonium salt cationic modifier is 3-acrylamide -2-hydroxypropyltrimethylammonium chloride, the polymer quaternary ammonium salt cationic modifier is polyamide polyamine epichlorohydrin.
[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 quater...
