As can be seen from tables 2 and 3, in comparative example 1, only unmodified cotton fibers are used for weaving the fabric, when dyeing is carried out, the affinity between the dye and the fibers is low, the dye is only attached to the surface of the fabric, and the color fastness of the finished fabric finally dyed is poor; the dyed fabric has no color spinning effect, and the surface of the fabric has serious color spots. In the comparative example 2, the content of the modified cotton is increased to 35%, the color fastness of the fabric is not obviously changed, and the difference is only 0.5 grade compared with the original fabric; however, the fabric surface color spinning effect is not obvious compared with the original fabric surface color spinning effect, and the color spinning effect is weaker because the proportion of the modified cotton fibers is increased, the dye adsorption amount of the fabric is increased, and the color spinning effect is weakened. In the comparative example 3, when the content of the modified cotton is increased to 50%, the color fastness of the fabric is reduced by 0.5-1 grade compared with the original color fastness, and the color fastness is obviously reduced; from the cloth cover effect, the color spinning effect of the cloth cover is not available and is close to the pure color effect, because a large amount of dye is adsorbed after the consumption of the modified cotton fiber is increased, because the surface charge effect is strong, the inward diffusion capability of dye molecules is weakened, the dye is accumulated on the surface in a large amount, various fastness is reduced finally, the color spinning effect is not available, and meanwhile, because the content of the modified cotton fiber in the fabric is increased, the cloth cover has a little peculiar smell. In the comparative example 4, the pretreatment desizing adopts alkali desizing, the using amount of caustic soda is 40-60g/L, the color fastness of the fabric is reduced to a certain degree, the fabric surface color spinning effect is not obvious, and the color is not uniform. This is because the cationic group on the modified cotton fiber undergoes some hydrolysis in the presence of high temperature and strong alkali, and the ionic force between the dye and the modified cotton fiber becomes weak, which results in the decrease of the dye adsorption capacity of the fabric and the strong amine odor. In the comparative example 5, no acidic leveling agent is added in the step 1 of the dyeing procedure, so that the color fastness of the fabric is reduced to a certain extent, and the color is not uniform. This is probably due to the fact that the modified cotton fibers have too strong an interaction with the dye, and the dye is adsorbed on the surface of the fabric in a short time. The acidic leveling agent is an amphoteric weak cationic polymer, can be preferentially adsorbed with reactive dyes, can be slowly released by prolonging the heat preservation time, and can be subjected to ionic action with modified cotton fibers, so that the dyes are finally dyed on the fabric. In the comparative example 6, the dosage of the acid leveling agent in the step 1 of the dyeing procedure is 8g/L, the color fastness of the fabric is not greatly different from that of the original fabric, but the fabric surface color spinning effect is not obvious. The reason is that the acid leveling agent is more, most of the reactive dyes are combined, only a small amount of the dyes dye the fabric, and finally the fabric surface color spinning effect is not obvious. In comparative example 7, a cationic softening agent was used for softening and setting in the post-finishing step. The color fastness of the fabric is obviously reduced, which is probably because the dye is resolved from the surface of the modified cotton fiber under the action of the cationic softening agent, and finally, various fastness is reduced. In comparative example 8, when the post-finishing step was performed for softening and setting, the non-ionic hydrophobic softening agent was used, and the color fastness was significantly decreased, probably because the hydrophobic softening agent required the addition of an emulsifier, which had an extraction function for dyes. In comparative example 9, the modified cellulose fibers and the unmodified cellulose fibers were mixed in the form of cotton sliver, and although the fastness was good, the cloth surface had obvious color stripes or nubs. This is probably because the modified cotton sliver and the unmodified cotton sliver are relatively fixed in position in the yarn structure, and the modified cotton fibers are relatively concentrated, thereby causing the defects of the external light of the cloth cover. In comparative example 10, salt and soda were added according to the conventional process, and although the various fastnesses were good, there was no effect of spinning because both the modified cotton fiber and the cotton fiber essentially belong to the cellulose fiber, i.e., the same fiber, and when dyed by the conventional process, it was impossible to dye the effect of spinning. In comparative example 111, when the pH of the dye solution was alkaline, the cloth surface color spinning effect was not significant, mainly because the reactive group of the reactive dye was covalently bonded to the fiber under alkaline conditions, thereby coloring the unmodified cellulose fiber as well. In comparative examples 12 and 13, when the pH was 10 to 11, the cloth was liable to show a large odor with yellowing, and the fastness was low because the modifier was hydrolyzed under a long-term high-temperature, alkaline condition; the pH value is 4-5, and the whiteness of the fabric is lower; in the invention, weakly acidic (6-7) oxygen bleaching is selected, which is mainly used for preventing the modified fiber from yellowing or hydrolyzing under alkaline conditions, and is one of the reasons why I emphasize that an acidic leveling agent and neutral soaping are needed in the following. The current modifiers are generally amine substances which are easy to hydrolyze under alkaline conditions and generate fishy smell, and because the oxygen bleaching process is mainly high-temperature steaming, the modifiers remain on the cloth surface during steaming, and are yellowed and accompanied with peculiar smell. Much better under acidic conditions. On the one hand, the strong acidity can cause too much strong damage to the cellulose fiber under high temperature conditions, and on the other hand, the strong acidity of the hydrogen peroxide water is relatively inactive. The end result is that once the modifiers on the cellulose fibers are destroyed, no color spinning effect is obtained and the fastnesses are also poor. In comparative example 14, when the pH of the cloth surface was alkaline during the soft setting, the color spinning effect of the fabric was not significant and a significant odor was accompanied.
