The invention discloses a dyeing pretreatment method for modified cellulose fibers and knitted fabrics woven with them. The method is prepared by the following steps: adding cellulose fibers and water to obtain a mixture a; adding water to the mixture a 1-2% of the total weight of the strong activator, 1.5-2.5% of the caustic soda and 1.5-2.5% of the cationic modifier are added and stirred to obtain a mixture b; the cellulose fibers in the mixture b are taken out and added cationic modifier, stir evenly, and then put the cellulose fibers into the mixture to obtain the mixture c; wash the cellulose fibers in the mixture c with water, dehydrate, and dry to obtain the modified cellulose fibers; the strong activator is composed of It is formulated with the following components by weight: nonionic penetrant, pH stabilizer, quaternary ammonium salt compound, and water. The present invention has the advantages of improving the surface and inner dyeing properties of cellulose fibers, and increasing the dye uptake of cellulose fibers as fabrics. |
