Embodiment 1
[0060] Modified cellulose fibers:
[0061] The modified cellulose fiber obtained through modification, the modified cellulose fiber is made of cellulose fiber through a small molecular quaternary ammonium salt cationic modifier and a high molecular weight quaternary ammonium salt cationic modifier as a cationic modifier, Carry out modification treatment, when the obtained pH value is 6.5-8.5, the Zeta electrode potential value is the modified cellulose fiber of 0-25mV; Described small molecule quaternary ammonium salt cationic modifier is epoxy quaternary ammonium salt compound, The high molecular weight quaternary ammonium salt cationic modifier is a cationic polyacrylamide compound.
[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 weig...
