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 , modified cellulose fibers are obtained after the modification treatment is completed; the small molecular quaternary ammonium salt cationic modifier is 3-acrylamide-2-hydroxypropyl trimethyl ammonium chloride, and the high molecular quaternary ammonium The salt cationic modifier is polyamide polyamine epichlorohydrin.
[0062] The above-mentioned process is the cellulose fiber modification process of the present invention, and when the pH value is 6.5-8.5, the Zeta electrode potential value is -5-15mV to obtain the modified cellulose fiber. Due to the small molecular weight of the small molecular quaternary ammonium salt cationic modifier, it can not only be...
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 , modified cellulose fibers are obtained after the modification treatment is completed; the small molecular quaternary ammonium salt cationic modifier is 3-acrylamide-2-hydroxypropyl trimethyl ammonium chloride, and the high molecular quaternary ammonium The salt cationic modifier is polyamide polyamine 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 f...
