Nylon 6 fiber is used as the second largest chemical fiber worldwide, and has the main characteristics of high breaking strength, excellent wear resistance, low weight, good elasticity and the like. In recent years, the awareness of people on health and environmental protection is increasingly enhanced, the technology of coloring nylon 6 fibers by using stock solution is also greatly developed, various colors are endowed to the fibers in the melt spinning process by adding color master batches, the printing and dyeing links in the production process of downstream enterprises are omitted, and the nylon 6 fiber has outstanding environmental protection characteristics. The black nylon 6 filament accounts for about 30% of the stock solution coloring nylon 6 in the current market, and is mainly applied to close-fitting articles such as swimwear, silk stockings and the like, thereby having wide market prospect.
In the preparation process of the black nylon 6 master batch, the carbon black has small particle size and high specific surface area, so that the unmodified carbon black and the master batch polyamide have poor compatibility, and agglomeration phenomenon is easy to occur, so that the uniform dispersion effect of the carbon black in the carrier resin is reduced, and the blackness and the coloring degree effect of the final spinning coloring are affected. On the other hand, in addition to the requirements of textiles for diversification, color beauty, environmental protection, etc., the functional requirements of garments are increasing, and the antibacterial function is attracting more and more attention from the industry. At present, silver antibacterial agents are commonly adopted in antibacterial fibers, but the safety of products is always in full of disputes because nano silver is easy to accumulate in a human body after being absorbed by the human body.

TABLE 2 antibacterial Property test results of the fibers produced in examples 1 to 4 and comparative example 1
The results show that the antibacterial rate of the candida albicans of the fiber produced in the comparative example 1 only reaches the national standard basic value (70%), and the more excellent the antibacterial performance of the candida albicans of the fiber produced in the experimental examples 1-4 is along with the increase of the ZnO content in the finished yarn, the more excellent the antibacterial effect of the candida albicans is, and the antibacterial effect of the candida albicans is effectively improved; in addition, the coliform bacteria inhibition rate of the produced fibers in experimental examples 1-4 is improved by 6% compared with comparative example 1, and experimental examples 1-4 are basically equivalent to comparative example 1 in terms of staphylococcus aureus bacteria inhibition rate.
Comprehensively comparing blackness, hue and antibacterial performance: in terms of blackness, examples 3, 4 were comparable in blackness; in terms of antibiosis, the antibacterial rates of the candida albicans, the escherichia coli and the staphylococcus aureus in the examples 3 and 4 are basically consistent; in terms of hue, the hue of example 3 is significantly more blue than that of example 4. Thus, the method of preparing black antimicrobial nylon 6 fiber with enhanced jetness and blue phase in the present invention may be preferred as example 3.
