Performance test
Detection method
And (3) detecting the antibacterial performance: after washing and drying, the antibacterial cloth of examples 1-19 and comparative example was tested for antibacterial performance according to the test methods in FZ/T01021-1992, test methods for antibacterial performance of fabrics, the washing times were 0, 10 and 50 respectively, and the antibacterial test of this time was performed for Staphylococcus aureus, and the results are shown in Table 3.
TABLE 3 antibacterial Properties of antibacterial cloths of examples 1-19 and comparative examples
Figure BDA0003182372970000081
By combining the example 1 and the comparative example and combining the table 3, it can be seen that, compared with the comparative example, the dyeing liquid in the example 1 comprises the dyeing agent and the adhesive, the dyeing agent can dye and has an antibacterial effect, and the adhesive bonds the dyeing agent to the cloth, so that the retention time of the dyeing agent on the cloth is prolonged, and the antibacterial performance of the cloth is further improved.
By combining the examples 1 to 5 and table 3, it can be seen that the dyeing condition of the cloth can be influenced by changing the proportional relationship between the dyeing agent and the binder in the dyeing solution, so that the antibacterial performance of the cloth is influenced, and when the addition amount of the binder is larger than that of the dyeing agent, the prepared cloth has better antibacterial performance.
By combining examples 5-10 and table 3, it can be seen that the proportions of the purple sweet potato extract, the rosa roxburghii tratt extract and the impatiens balsamina extract in the coloring agent are different, the influence on the antibacterial performance of the cloth is different, the dyeing effect of the cloth can be increased through the synergistic effect of the purple sweet potato extract, the rosa roxburghii tratt extract and the impatiens balsamina extract, and meanwhile, the antibacterial performance of the cloth can be improved.
In combination with examples 10 to 13 and table 3, it can be seen that the raw material ratios of the components in the binder affect the dyeing condition and antibacterial property of the fabric, and the antibacterial property of the fabric is improved by adjusting the synergistic effect of the components in the binder.
Combining with examples 13-19 and table 3, it can be seen that the antibacterial property of the cloth can be improved by immersing the cloth in the aqueous solution of tannic acid, and meanwhile, the color fastness of the cloth can be further improved by adding the color fixing agent into the dyeing liquid, and the antibacterial property of the cloth can be improved at the same time.
