Embodiment 1
[0060] Modification process of cellulose fiber:
[0061] Put the cellulose fiber into the container, add water to the container, and then modify the cellulose fiber with two cationic modifiers, the small molecule quaternary ammonium salt cationic modifier and the high molecular quaternary ammonium salt cationic modifier After the modification treatment is completed, modified cellulose fibers are obtained; the small molecular quaternary ammonium salt cationic modifier is an azetidine cationic compound, and the high molecular quaternary ammonium salt cationic modifier is polyamide polyamide Amine epichlorohydrin.
[0062] The above process is the cellulose fiber modification process of the present invention, and the modified cellulose fiber can be obtained with a Zeta electrode potential value of 0-20mV when the pH value is 6.5-8.5. 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 ...
Embodiment 2
[0064] Modification process of cellulose fiber:
[0065] Put the cellulose fiber into the container, add water to the container, and then modify the cellulose fiber with two cationic modifiers, the small molecule quaternary ammonium salt cationic modifier and the high molecular quaternary ammonium salt cationic modifier After the modification treatment is completed, modified cellulose fibers are obtained; the small molecular quaternary ammonium salt cationic modifier is an azetidine cationic compound, and the high molecular quaternary ammonium salt cationic modifier is polyamide polyamide Amine epichlorohydrin.
[0066] The cellulose fibers are selected from viscose filaments, viscose staple fibers, modal, tencel, cotton fibers, yarns and fabrics made from the aforementioned cellulose fibers.
[0067] The modification process of the present invention is applicable to all kinds of cellulose fibers, and also includes twisted yarns (hank form or cheese form) of these cellulose f...
