TABLE 1 test Experimental data for application examples 1-12 and comparative application examples 1-6

By comparing the test experimental data in table 1, it can be seen that the cotton knitted fabrics with the mosquito-repellent and antibacterial functions of application examples 1-12 have a mosquito repelling rate of not less than 73% and a mosquito repelling rating of class a; compared with the application examples 1-4, the cotton knitted fabric with the mosquito repelling and antibacterial functions has the mosquito repelling rate of 38-46%, and the mosquito repelling grade is C, which shows that the cotton knitted fabric with the mosquito repelling and antibacterial functions has a strong mosquito repelling effect.

The mosquito-repellent and antibacterial cotton knitted fabric of application examples 1-12 has an inhibition rate of more than or equal to 96.1% on staphylococcus aureus, an inhibition rate of more than or equal to 93.2% on escherichia coli and an inhibition rate of more than or equal to 85.6% on candida albicans; compared with the application examples 1-4, the mosquito-repellent and antibacterial cotton knitted fabric has the advantages that the bacteriostasis rate of staphylococcus aureus is 88.7-90.2%, the inhibition rate of escherichia coli is 86.9-88.1%, and the inhibition rate of candida albicans is 80.5-81.6%.

The four components of the citronella essential oil, the lavender essential oil, the artemisia essential oil and the eucalyptus essential oil provided by the invention have obvious synergistic interaction, and the mosquito-repellent and antibacterial effects of the material can be greatly improved.

In addition, after the cotton knitted fabric with the mosquito-repellent and antibacterial functions of the application examples 1-12 is washed for 30 times, the mosquito repelling rate is more than or equal to 65 percent, the mosquito repelling rating is B grade, the bacteriostasis rate on staphylococcus aureus is more than or equal to 91.1 percent, the inhibition rate on escherichia coli is more than or equal to 88.7 percent, and the inhibition rate on candida albicans is more than or equal to 82.6 percent; and after the cotton knitted fabrics with the mosquito-repellent and antibacterial functions of the application examples 5 and 6 are washed for 30 times, the repellent rate to mosquitoes is 31-32%, the mosquito-repellent rating is C, the inhibition rate to staphylococcus aureus is 75.4-76.2%, the inhibition rate to escherichia coli is 68.8-69.7%, and the inhibition rate to candida albicans is 56.2-57.8%. The cotton knitted fabric with the mosquito-repellent and antibacterial functions still has good mosquito-repellent and antibacterial effects after being washed for 30 times.

The genipin and the tannic acid are added into the cotton knitted fabric treatment liquid provided by the invention to perform synergism, so that the bonding strength of the essential oil microcapsules and the surface of cotton fibers in the cotton knitted fabric is increased, the durability of the mosquito-repellent and antibacterial functions of the plant traditional Chinese medicines is increased, and the water-washing resistance of the functions is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
