[0021] The detailed embodiment is a ventilated and dirt-resistant type knitted vamp, and the structure schematic view thereof is shown in the drawing, which comprises an outer layer fabric 1, a middle layer fabric 2 and an inner layer fabric 3. Figures 1-4 The outer layer fabric 1 is knitted by a first yarn 4, the surface of the first yarn 4 is coated with an antifouling coating 5, the middle layer fabric 2 is knitted by a second yarn 6, and the inner layer fabric 3 is fixed by sewing with the outer layer fabric 1 and the middle layer fabric 2.
[0022] In the embodiment, the anti-fouling coating 5 is nano-silica or nano-titanium dioxide, which can effectively increase the water and oil resistance of the yarn surface. The nano-silica or nano-titanium dioxide can be modified by doping a conjugated polymer, such as polythiophene, polyaniline, polypyrrole, or polyvinyl alcohol (PVA).
[0023] As shown in Figure 2 In the embodiment, the outer fabric 1 and the middle fabric 2 adopt a weft flat structure.
[0024] In order to improve the strength of the first yarn 4, as shown in Figure 4 In the embodiment, the first yarn 4 is a blend of several polyester filaments 401 and one spandex filament 402.
[0025] In the embodiment, the fineness of the polyester filaments 401 is 80-120D, and the fineness of the spandex filament 402 is 40-60D. Specifically, the polyester filaments 401 are antistatic and flame-retardant filaments, which can reduce the influence of static electricity on the upper cloth and improve the fire resistance of the upper cloth.
[0026] In the embodiment, the second yarn 6 is a blend of cotton, wool, and chitin fibers. Chitin fiber is an excellent antibacterial fiber that can resist the reproduction and proliferation of various microorganisms such as fungi and molds, further enhancing the performance of the fabric.
[0027] In order to improve comfort, in the embodiment, the inner fabric 3 is knitted from one or more of bamboo fiber, milk protein filament, silk, and cotton. Bamboo fiber, milk protein filament, silk, and cotton are all good skin-friendly artificial or natural fibers that can reduce the roughness of the inner fabric 3 and improve the comfort of the upper cloth.
[0028] Working principle: By setting the outer fabric 1, the middle fabric 2, and the inner fabric 3, the outer fabric 1 is a core-spun yarn knitted from polyester filaments 401 and one spandex filament 402, and the surface of the first yarn 4 is coated with an anti-fouling coating 5, which not only has the advantages of wear resistance and easy cleaning, but also prolongs the service life of the upper cloth. The outer fabric 1 and the middle fabric 2 are knitted from yarns, which have good air permeability. The chitin fiber in the middle fabric 2 is an excellent antibacterial fiber that can effectively resist the reproduction and proliferation of various microorganisms such as fungi and molds, reducing the odor inside the shoe. The inner fabric 3 uses good skin-friendly artificial or natural fibers to improve the comfort of the upper cloth.
[0029] All technical features in the embodiment can be freely combined according to actual needs.
[0030] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
