Cotton fabric is fast and wear resistant, can be washed and ironed at high temperature, and cotton fabric is comfortable to wear due to rapid moisture absorption and removal. However, cotton is a biological material, contains abundant cellulose, is a complex polysaccharide, provides nutrients for flour product mold in a certain temperature environment, is extremely easy to be damaged by mold and insects and ants, changes appearance and reduces strength, and in addition, in order to improve the appearance aesthetic feeling of cotton fabrics, the spinning yarn is generally required to be dyed, but the natural cotton yarn has poor adsorption and fixation performance on dye, so that the improvement treatment is urgently needed, and the antibacterial property and dyeing property of cotton fabrics are improved on the premise of not influencing the use performance of cotton fabrics at present.
The existing method improves the processing technology of cotton yarns, such as application number: CN201610669894.2 discloses an antibacterial high-count cotton spinning yarn made of silver chelate fiber and a preparation method thereof. The invention relates to an antibacterial high-count cotton spinning yarn made of silver chelate fibers and a preparation method thereof, belonging to the technical field of textile materials, wherein the yarn contains 0.2-3 wt% of silver chelate fibers, and the balance is conventional fibers; the preparation method comprises the steps of mixing cotton nets for multiple times, mixing cotton slivers for multiple times and spinning to obtain yarns with uniformly distributed silver chelate fibers, wherein the twist coefficient of the yarns is controlled to be 270-450; controlling the yarn count to be 10-120 s; the silver content of the yarn is not less than 60 ppm; the yarn has excellent silver ion releasing performance and permanent washing resistance after encountering water with ions. Although the method effectively improves the antibacterial property of the cotton yarn, the method obtains the yarn with uniformly distributed silver chelate fibers by mixing the cotton nets for multiple times and mixing and spinning the cotton slivers for multiple times, has the problem of insufficient silver chelate and fiber cohesive force, and hinders the application of the cotton yarn to a certain extent.

Control group
The application numbers are: CN201610669894.2 discloses an antibacterial high-count cotton spinning yarn of silver chelate fiber and a preparation method thereof.
In order to compare the effects of the invention, the yarns prepared in examples 1 to 6 and the corresponding method of the control group are respectively woven into woven tapes by adopting plain weave, and the yarns are respectively dyed and dyed by taking disperse red 3B, disperse yellow S-4GL and disperse dark blue HGL as disperse dyes according to the method of (Huang Yongdong. polyester woven tape dyeing technology discussion [ J ] scientific research and production, 2019(3):1 to 2.) and then subjected to performance test, specifically:
(1) and (3) mildew prevention test:
placing each group of dyed woven tape test pieces correspondingly prepared in an environment with the temperature of 25-30 ℃ and the humidity of 65-75%, starting to visually observe the bacterial infection area and the mould growth condition of the woven tape after 5 weeks, observing every 4 weeks later, recording, and grading damage values according to table 1 so as to evaluate the mould-proof and antibacterial effects (the specification of the woven tape test pieces is 200mm in length and 200mm in width), wherein the specific test comparison data are shown in the following table 2:
TABLE 1
Figure 341931DEST_PATH_IMAGE002
TABLE 2
Figure 790229DEST_PATH_IMAGE004
As can be seen from the above table 2, the processing method of the cotton yarn with strong antibacterial and color fixing capabilities provided by the invention effectively improves the mildew-proof antibacterial capability of the cotton yarn without changing the spinning mode, and has a good application prospect.
(2) Determination of the fixation Rate
Washing off unfixed hydrolysis dye on the woven belt, and then calculating the fixation rate of the sample on the woven belt according to the optical density values of the standard soap solution and the soap boiling residual liquid. Combining the collected soaping residual liquid and washing liquid, diluting with standard soap liquid by the same times, and respectively measuring absorbance values D of the soaping residual liquid and the standard soap liquid at the maximum absorption wavelength of the soap liquid by using an ultraviolet spectrophotometeriAnd D0And then calculating the fixation rate by using the following formula: f (%) -, E-D1/D0 x 100%, each group was tested in 6 replicates, and the average was taken as the final test result, and the data for the specific test is shown in FIG. 1.
As can be seen from FIG. 1, the invention provides a processing method of cotton yarn with strong antibacterial and color fixing capabilities, the color fixing rate of the cotton yarn is as high as 94.5%, while the dye uptake of the cotton yarn of the control group is only 32.9%, thus the color fixing performance of the cotton yarn prepared by the method is obviously better than that of the cotton yarn prepared by the method of the control group.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and the present invention is not limited to the illustrated embodiments, and all the modifications and equivalents of the embodiments may be made without departing from the spirit of the present invention.
