Embodiment 1
[0060] Modified cellulose fibers:
[0061] A modified cellulose fiber obtained through modification, the modified cellulose fiber is modified by a small-molecular quaternary ammonium salt cationic modifier and a high-molecular quaternary ammonium salt cationic modifier as the cationic modification of the cellulose fiber Agent, 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 0-15mV; Described small molecule quaternary ammonium salt cationic modifier is epoxy quaternary ammonium salt The epichlorohydrin parent derivative, the high molecular weight quaternary ammonium salt cationic modifier is cationic starch.
[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 hig...
