[0002] A tent is a shed propped up on the ground to protect against wind, rain and sunlight and for temporary living. It is usually made of canvas and can be removed and moved at any time together with the supporting materials. The canvas is the main structure of the tent, and its fabric material can affect the tent's sunshade, shielding and moisture permeability.

[0003] For example, the existing patent publication number CN211106068U provides a new waterproof and breathable tent special fabric, including a reflective layer, a waterproof layer is arranged at the bottom of the reflective layer, a corrosion-resistant layer is arranged at the bottom of the waterproof layer, an elastic layer is arranged at the bottom of the corrosion-resistant layer, a quick-drying layer is arranged at the bottom of the elastic layer, a moisture-absorbing layer is arranged at the bottom of the quick-drying layer, and a waterproof and breathable layer is arranged at the bottom of the moisture-absorbing layer. The utility model, through the design of the reflective layer, highly reflects the sun's infrared and ultraviolet rays, has a high thermal reflectivity, and through the cooperation of the waterproof layer and the corrosion-resistant layer, prevents rainwater from corroding the fabric, thereby improving the service life of the tent. Through the design of the waterproof and breathable layer, the polytetrafluoroethylene resin film has the functions of waterproofing, moisture permeability and warmth preservation. Through the cooperation of the quick-drying layer and the moisture-absorbing layer, it is convenient to quickly absorb and evaporate the moisture inside the tent, improve the comfort, thereby achieving the effect of waterproofing and moisture permeability, and solving the problem that the existing tent is only waterproof but not moisture permeable.

[0004] The above-mentioned fabrics mainly achieve waterproof and moisture permeability of the tent through the physical properties of the fabric interlayer itself. The fabric needs to be folded before and after the tent is disassembled and erected. The large number of interlayers in the above-mentioned fabrics increases the possibility of interlayer separation during the folding process of the fabric, affecting the service life of the tent fabric.

[0005] Therefore, a waterproof and breathable tent fabric is proposed to solve the above problems. Utility Model Content

[0010] Preferably, a filler is provided between adjacent side walls of the sandwich base layer and the outer layer of fabric, and the filler is located outside the conical tube, the central pillar and the shielding cover.

[0011] Preferably, the outer fabric layer and the inner fabric layer are made of breathable materials.

[0012] Preferably, the interlayer base layer is made of waterproof and airtight material.

[0013] Preferably, the conical tube and the shielding cover are made of flexible, waterproof and airtight materials.

[0014] Beneficial effects of the utility model:

[0015] In the utility model, a fabric body is composed of a fabric outer layer, a fabric interlayer and a fabric inner layer, wherein the interlayer base layer and the conical tube to which the fabric interlayer belongs are made of waterproof and airtight materials, but the cooperation between the through holes on the interlayer base layer and the conical tube allows air to pass through the hollow space thereof, and will not hinder the moisture permeability and breathability of the fabric itself; the fabric interlayer is respectively connected to the fabric outer layer and the fabric inner layer through a central pillar, which can increase the connection stability between the fabric outer layer, the fabric interlayer and the fabric inner layer; the arrangement of the fabric interlayer ensures the waterproof and moisture permeability of the tent fabric while reducing the number of fabric interlayers, reducing the possibility of interlayer separation during the folding of the fabric, and increasing the practicality of the device.

[0027] like Figure 2As shown, a central pillar 23 is installed inside the conical cylinder 22, and the central pillar 23 passes through the conical cylinder 22 and is fixedly connected to the adjacent side walls of the outer fabric layer 1 and the inner fabric layer 3, respectively. The fabric interlayer 2 is connected to the outer fabric layer 1 and the inner fabric layer 3 through the central pillar 23, thereby increasing the stability of the connection between the outer fabric layer 1, the interlayer 2 and the inner fabric layer 3;

[0028] like Figure 2 As shown, a shielding cover 231 is fixedly connected to the outer wall of the central pillar 23 near one end edge, and the shielding cover 231 is located above one end of the conical cylinder 22. The central pillar 23 shields the upper opening of the conical cylinder 22 through the shielding cover 231, preventing rainwater that penetrates from the outer layer 1 of the fabric from sinking to the bottom of the inner layer 3 of the fabric through the conical cylinder 22 and the through hole 211, thereby increasing the rationality of the structure;

[0029] like Figure 2 As shown, a filler 4 is provided between the adjacent side walls of the sandwich base layer 21 and the outer fabric layer 1, and the filler 4 is located outside the conical tube 22, the central pillar 23 and the shielding cover 231.

[0031] Working principle: The outer fabric layer 1, the interlayer 2 and the inner fabric layer 3 form the main fabric body. After the fabric is processed into a tent, rainwater penetrates from the outer fabric layer 1 into the interlayer 2. The interlayer base layer 21, the conical tube 22 and the shielding cover 231 are made of waterproof and airtight materials, so that rainwater cannot penetrate into the inner fabric layer 3. The inner fabric layer 3 is similar to the outer fabric layer 1 and is made of breathable material, so that the air inside the tent can flow out, thereby ensuring the moisture permeability of the tent itself. The interlayer 2 allows air to flow out through the cooperation between the interlayer base layer 21 and the conical tube 22. The hollow part passes through, and the fabric interlayer 2 is connected to the fabric outer layer 1 and the fabric inner layer 3 through the central pillar 23, thereby increasing the stability of the connection between the fabric outer layer 1, the fabric interlayer 2 and the fabric inner layer 3.

The gaps outside the multiple conical tubes 22, the central pillar 23 and the shielding cover 231 on the interlayer base layer 21 are filled with the filling material 4.
