Description

Technical Field

[0001] The utility model relates to a tent and its hydrostatic pressure resistant polyester fabric. Background Technique

[0002] With the improvement of people's living standards, more and more people choose to travel on weekends and often set up tents in the wild.

[0003] At present, a Chinese patent with the authorization announcement number CN218660840U discloses a moisture-proof and sound-insulating tent fabric, which includes a tent base fabric. A sound-insulating layer is arranged on the outer side of the tent base fabric, a moisture-proof layer is arranged on the outer side of the sound-insulating layer, and a protective layer is arranged on the outer side of the moisture-proof layer. Arranging the sound-insulating layer on the outer side of the tent base fabric can improve the sound insulation of the tent fabric, making it difficult for external noise to penetrate, and can effectively improve the camping experience.

[0004] Arranging the moisture-proof layer on the outer side of this tent fabric can improve the moisture-proof property of the tent fabric, making it difficult for external water vapor to penetrate, and can effectively improve the camping experience. Arranging the protective layer on the outer side of the moisture-proof layer can protect the sound-insulating layer and the moisture-proof layer, making it difficult for the sound-insulating layer and the moisture-proof layer to be damaged.

[0005] However, in life, when people sit inside the tent, due to the obstruction of the moisture-proof layer, the water vapor inside the tent can only be discharged through the opening of the tent. Generally, the opening is located on the side of the tent, but the water vapor moves vertically upward, so condensed water will form on the top of the tent, and it is more obvious when the sky clears after rain, which will affect the comfort. Content of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide a hydrostatic pressure resistant polyester fabric to achieve the purpose of improving comfort.

[0007] To solve the above technical problems, the technical solution of the utility model is: a hydrostatic pressure resistant polyester fabric, which includes a polyester base layer. The polyester base layer includes woven warp and weft. There is a TPE tube in the cavity surrounded by the warp and weft. There is a water absorption block in the TPE tube. One end of the TPE tube has a protective net, and the other end has a closed part. The TPE tube is located inside the closed part. A plurality of positioning holes for positioning the warp and weft are opened on the outer wall of the TPE tube. A reinforcing layer is coated on the side of the polyester base layer facing away from the protective net, and a waterproof layer is coated on the reinforcing layer.

[0008] To implement the above technical solution, after the water vapor moves upward and contacts the polyester base layer, the water vapor passes through the protective net and contacts the water-absorbing block. The water vapor is absorbed by the water-absorbing block, so that the polyester base layer remains dry, achieving the purpose of improving comfort. After the rain falls, it is blocked by the waterproof layer, making it difficult for the rain to penetrate the polyester base layer, and having a good effect of hydrostatic pressure resistance. Moreover, the setting of the reinforcement layer makes the waterproof layer not easy to detach from the polyester base layer, greatly improving the service life. When the weather is fine, the water in the water-absorbing block can be evaporated and reused. The setting of the protective net and the positioning holes makes the water-absorbing block not easy to fall out of the TPE pipe. The TPE pipe has good environmental protection and flame retardancy. Moreover, the setting of the positioning holes and the closed part makes the TPE pipe more stable on the polyester base layer.

[0009] As a preferred solution of the present utility model, the reinforcement layer includes a polyester diol layer, and the thickness of the polyester diol layer is 45 - 50 microns.

[0010] To implement the above technical solution, the polyester diol layer can increase the bonding force between the polyester base layer and the waterproof layer, so as to prevent the waterproof layer from peeling off or whitening from the polyester base layer.

[0011] As a preferred solution of the present utility model, the reinforcement layer further includes a barbed layer, and a plurality of the barbed layers are fixed on the polyester diol layer, and a part of the barbed layer is located on the side of the polyester diol layer facing away from the polyester base layer.

[0012] To implement the above technical solution, the barbed layer is placed in the polyester diol layer, and a part of the barbed layer extends out of the polyester diol layer. After the waterproof layer is coated on the reinforcement layer, a part of the barbed layer can be immersed in the waterproof layer to further improve the firmness of the waterproof layer.

[0013] As a preferred solution of the present utility model, the barbed layer is made of nickel-chromium alloy and is arranged in a J shape.

[0014] To implement the above technical solution, nickel-chromium alloy has good electrical conductivity and oxidation resistance, and has a long service life. At the same time, due to good electrical conductivity, it is not easy to generate static electricity, improving the comfort during winter use.

[0015] As a preferred solution of the present utility model, the waterproof layer includes a waterborne polyurethane coating and plastic filaments. The plastic filaments are mixed in the waterborne polyurethane coating. The waterborne polyurethane coating is coated on the side of the reinforcement layer facing away from the polyester base layer, and the plastic filaments pass through the barbed layer.

[0016] To implement the above technical solution, the waterproof layer is coated on the reinforcement layer. Polyester diol can increase the bonding force between the waterborne polyurethane coating and the polyester base layer. Some plastic filaments pass through the barbed layer, further making it difficult for the waterborne polyurethane coating to peel off from the reinforcement layer. After the waterborne polyurethane coating cures on the surface of the polyester base layer, it forms a continuous coating film, which can isolate corrosive substances such as water, oxygen, and salts, preventing electrochemical corrosion or leakage of the coated object. Moreover, the waterborne polyurethane coating has excellent chemical stability such as acid and alkali resistance, salt spray resistance, and oxidation resistance, and can resist various harsh environmental conditions, preventing aging, cracking, and peeling of the coating film. The waterborne polyurethane coating has physical properties such as high elasticity, high elongation rate, and high toughness, which can buffer physical effects such as thermal expansion and contraction, stress deformation, and vibration shock of the coated object, preventing damage and penetration of the coating film, so that it has excellent hydrostatic pressure resistance.

[0017] The second object of the present utility model is to provide a tent to achieve the purpose of improving waterproof performance.

[0018] To solve the above technical problems, the technical solution of the present utility model is: a tent, including a support rod, and further including the hydrostatic pressure resistant polyester fabric described above. The support rod passes through the hydrostatic pressure resistant polyester fabric. A protective cover is fixedly connected to the top end of the support rod. A locking structure for positioning the hydrostatic pressure resistant polyester fabric is provided on the support rod.

[0019] To implement the above technical solution, pass the support rod through the hydrostatic pressure resistant polyester fabric, fix the protective cover on the support rod, and fix the hydrostatic pressure resistant polyester fabric with the locking structure. When rain falls, through the blockage of the protective cover, it is difficult for rainwater to penetrate through the gap between the hydrostatic pressure resistant polyester fabric and the support rod, improving the waterproof performance.

[0020] As a preferred solution of the present utility model, the locking structure includes a positioning ring and a locking ring. The positioning ring is sleeved outside the support rod and fixed on the support rod. The locking ring is threadedly connected to the support rod. A locking area for clamping the hydrostatic pressure resistant polyester fabric is formed between the locking ring and the positioning ring.

[0021] To implement the above technical solution, sleeve the hydrostatic pressure resistant polyester fabric on the support rod, make the hydrostatic pressure resistant polyester fabric contact the positioning ring, and then threadedly connect the locking ring to the support rod, so that the locking ring and the positioning ring respectively press against both sides of the hydrostatic pressure resistant polyester fabric, greatly improving the sealing performance, waterproof performance, and stability.

[0022] As a preferred solution of the present utility model, the projection of the positioning ring on the protective cover is located inside the protective cover, and the side of the protective cover facing away from the positioning ring has an arc surface.

[0023] To implement the above technical solution, when rainwater falls, the arc surface on the protective cover has a good guiding effect, making it difficult for rainwater to enter between the hydrostatic pressure-resistant polyester fabric and the support rod, so as to further improve the waterproof performance.

Detailed Description of the Invention

[0029] The following further details the specific embodiments of the present invention in conjunction with the drawings, so that the technical solutions of the present invention are easier to understand and master.

[0030] Embodiment 1: As shown in Figure 1 and Figure 2 , a hydrostatic pressure-resistant polyester fabric includes a polyester base layer 1, and the polyester base layer 1 is woven from a warp 11 and a weft 12. A cylindrical TPE pipe 2 is provided in the cavity surrounded by the warp 11 and the weft 12, and a water-absorbing block 31 is placed in the TPE pipe 2. The volume of the water-absorbing block 31 before water absorption accounts for 2 / 3 of the internal volume of the TPE pipe 2. The water-absorbing block 31 is made of PVA sponge.

[0031] A protective net 3 is fixedly connected to the lower end of the TPE pipe 2. The protective net 3 is provided to prevent the water-absorbing block 31 from falling out of the TPE pipe 2, and water vapor can pass through the protective net 3 to contact the water-absorbing block 31. A closing part 32 is provided at the upper end of the TPE pipe 2. Both the protective net 3 and the closing part 32 are made of TPE2 material.

[0032] The cross-sectional area of the closing part 32 is larger than the cross-sectional area of the TPE pipe 2. A plurality of positioning holes for positioning the warp 11 and the weft 12 are provided on the outer wall of the TPE pipe 2, and the plurality of positioning holes are arranged along the length direction of the TPE pipe 2.

[0033] On the side of the polyester base layer 1 facing away from the protective net 3, a reinforcement layer 4 is coated. The reinforcement layer 4 includes a polyester diol layer 41 and a barb layer 42. Among them, the thickness of the polyester diol layer 41 is 47 microns. The barb layer 42 is made of nickel-chromium alloy and is arranged in a J shape; a plurality of barb layers 42 are fixed on the polyester diol layer 41, and a part of the barb layer 42 is located on the side of the polyester diol layer 41 facing away from the polyester base layer 1 and is exposed.

[0034] A waterproof layer 5 is coated on the reinforcement layer 4. The waterproof layer 5 includes a waterborne polyurethane coating 51 and plastic filaments 52. Among them, the plastic filaments 52 are strip-shaped and mixed in the waterborne polyurethane coating 51. The waterborne polyurethane coating 51 is coated on the side of the reinforcement layer 4 facing away from the polyester base layer 1, and part of the plastic filaments 52 pass through the barb layer 42.

[0035] During use, with the waterproof layer 5 facing upwards, water vapor moves along the surface of the polyester base layer 1, passes through the protective net 3 and contacts the water absorption block 31 and is absorbed by the water absorption block 31 to keep it dry, achieving the purpose of improving comfort. When rain falls, due to the waterproof effect of the waterborne polyurethane coating 51, rainwater is not easily permeated through the polyester base layer 1, having a good hydrostatic pressure resistance effect. And, due to the setting of the reinforcement layer 4, the waterborne polyurethane coating 51 is not easily peeled off or fallen off and has a long service life; the water absorption block 31 can be reused after being dried in the sun.

[0036] Example 2: As Figure 3 and Figure 4 shown, a tent includes a cylindrical support rod 6 and the hydrostatic pressure resistant polyester fabric in Example 1. A circular through hole 61 is provided in the hydrostatic pressure resistant polyester fabric. The support rod 6 is passed through the through hole 61. A locking structure 7 for positioning the hydrostatic pressure resistant polyester fabric is provided on the support rod 6.

[0037] The locking structure 7 includes a positioning ring 71 and a locking ring 72. A threaded groove is provided on the outer wall of the support rod 6, and the locking ring 72 is threadedly connected to the support rod 6. Then, the hydrostatic pressure resistant polyester fabric is sleeved on the support rod 6. The positioning ring 71 is sleeved on the outside of the support rod 6 and fixed to the support rod 6.

[0038] A locking area for clamping the hydrostatic pressure resistant polyester fabric is formed between the locking ring 72 and the positioning ring 71. The locking ring 72 is rotated so that the locking ring 72 and the positioning ring 71 respectively press against both sides of the hydrostatic pressure resistant polyester fabric to fix the hydrostatic pressure resistant polyester fabric.

[0039] A protective cover 8 is fixedly connected to the top end of the support rod 6. The area of the lower surface of the protective cover 8 is larger than the area of the upper surface of the positioning ring 71. An arc surface 81 is provided on the side of the protective cover 8 facing away from the positioning ring 71.

[0040] When rain falls, due to the shielding effect of the protective cover 8, the rainwater falls along the arc surface 81 and is not easily introduced into the gap between the through hole 61 and the support rod 6, thereby greatly improving the waterproof property.

[0041] Certainly, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
