Embodiment 1
[0024] This embodiment provides a kind of cloth, comprises inner layer cloth, middle layer cloth and outer layer cloth; figure 1 As shown, the inner layer cloth, the middle layer cloth and the outer layer cloth are woven into one by means of double-sided warp knitting with far-infrared fibers as yarns; Ventilation holes are distributed alternately; it can not only play the role of ventilation, but also ensure the warm function of the fabric to the greatest extent
[0025] The middle layer cloth is far-infrared fiber; the inner layer surface cloth and the outer layer surface cloth are woven from core-spun yarns blended with polyester fibers, nylon fibers, and spandex fibers, and the polyester fibers in the core-spun yarns The mass proportion of nylon fiber is 42.34%-52.14%, the mass proportion of nylon fiber is 18.56%-27.44%, and the mass proportion of spandex fiber is 25.47%-30.22%;
[0026] The core-spun yarn is soaked in 1%-2% nano-silver solution for 0.5-2min, and then dri...
Embodiment 2
[0034] The core-spun yarn described in the experimental content was prepared according to the grouping situation in Table 1 in Example 1, and its preparation conditions were optimized to obtain the best antibacterial ability. After the treatment is completed, according to the content of the invention, the core-spun yarn and far-infrared fiber treated with nano-silver are woven by double-sided warp knitting. figure 2 Cloth of the construction shown.
[0035] Bacterial culture and antibacterial verification method (taking Staphylococcus aureus as an example): Cultivate Staphylococcus aureus overnight to OD600=0.6, dilute the bacterial solution to 1000CFU / ml with PBS buffer after microscopic counting, and spray evenly to The above-mentioned cloth surface after ultraviolet disinfection was placed in a sterile petri dish, and incubated at a constant temperature of 37° C. for 3 days. The cloth was taken out and covered on the sterile LB solid medium for 5 minutes, then the cloth w...
Embodiment 3
[0040] The antibacterial cloth obtained by immersing 2% nano-silver for 2 minutes and then drying at 115°C for 5 minutes was washed 5 times, 10 times, 20 times, and 50 times respectively, and the washing time was 15 minutes each time, and the washing temperature was 40°C. Then check its antibacterial activity (taking Staphylococcus aureus as an example) according to the method described in Example 2, record the area of the cloth before and after washing simultaneously, and carry out shrinkage calculation. The results are shown in Table 2, the antibacterial cloth of the present invention can have excellent antibacterial ability after 20 times of washing, although the antibacterial cloth after 50 times of washing has significantly reduced antibacterial activity, it still has stronger antibacterial ability. The shrinkage rate of the fabric can also meet the requirements of the relevant national standards, and the shrinkage rate does not increase with the number of washings.
