[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment 1

[0016] Combination Figure 1-2 The present embodiment is described in detail. A heat-insulating and thermal-retaining polyester composite fabric comprises: a composite base fabric layer 1, a thermal-retaining layer 2, a thermal-insulating layer 3, a waterproof layer 4 and a wear-resistant layer 5; the thermal-retaining layer 2 is arranged between the base fabric layer 1 and the thermal-insulating layer 3; the waterproof layer 4 is arranged between the thermal-insulating layer 3 and the wear-resistant layer 5; the base fabric layer 1 is 400D polyester oxford fabric; the thermal-insulating layer 3 comprises a first fabric layer 6, a thermal-insulating material 7 and a second fabric layer 8 which are arranged in sequence, and the first fabric layer 6, the thermal-insulating material 7 and the second fabric layer 8 are composited by quilting; the waterproof layer 4 is a polytetrafluoroethylene waterproof and breathable membrane.

[0017] The 400D polyester Oxford cloth has the advantages of being thick, durable, breathable, etc., and is suitable for making tent cloth.

[0018] The polytetrafluoroethylene waterproof breathable membrane is a porous breathable film made of high molecular polymer through a special process. Its pore size is 10,000 times smaller than that of water droplets and 700 times larger than that of water vapor, so it is waterproof and breathable.

[0019] Furthermore, the thermal insulation layer 2 is interwoven with hygroscopic and heating yarns, and the hygroscopic and heating yarns are twisted together with viscose fiber yarns and Yirebao fiber yarns. Yirebao fiber is a modified propylene fiber with high moisture regain, and its moisture regain rate is about 23%. At the same time, it can repeatedly absorb and release moisture for a long time according to the environment, and generate adsorption heat while absorbing moisture, which is suitable for weaving hygroscopic and heating fabrics. In addition, Yirebao fiber also has high flame retardancy and good antibacterial properties, and does not contain any heavy metals. The thermal insulation layer interwoven with the hygroscopic and heating yarn has a high moisture regain, strong moisture absorption capacity, and excellent heating effect.

[0020] Furthermore, the first fabric layer 6 and the second fabric layer 8 are interwoven with polyester filaments.

[0021] Furthermore, the thermal insulation material 7 is encapsulated aerogel fiber. Polar bear hair has a porous core and a dense shell structure, which can prevent heat loss, and its micron pores can capture a large amount of still air, effectively preventing heat conduction and convection. Encapsulated aerogel fiber has a similar thermal insulation mechanism, and its preparation method is as follows: first, aerogel fiber is obtained by freeze spinning. A well-dispersed polymer solution is used for freeze spinning, and continuous and stable ice fibers are generated by cold zone extrusion, and collected by a motor. Subsequently, the collected frozen fibers are freeze-dried to retain the lamellar porous structure in the fiber. Finally, the aerogel fiber is coated with a thermoplastic polyurethane solution and dried with a coating drying device to obtain an encapsulated aerogel fiber with a bionic core-shell structure. The encapsulation layer can not only provide sufficient strength for the aerogel fiber, but also protect its thermal insulation performance during cyclic stretching, and the thermal insulation performance of the encapsulated aerogel fiber is very stable, and this property can remain unchanged even in the case of daily wear and tear.

[0022] Furthermore, the wear-resistant layer 5 is interwoven with ultra-high molecular weight polyethylene fiber filaments. Ultra-high molecular weight polyethylene fiber, also known as high-strength high-modulus polyethylene fiber, has low fiber density, low elongation at break, large work at break, outstanding impact resistance and cut resistance, and good wear resistance. Therefore, the wear-resistant layer 5 can play a good protective role, protecting the heat-insulating and warm polyester composite fabric from being easily worn and damaged when used as a tent cloth, and having a long service life.

[0023] Embodiment 2

[0024] The difference from the first embodiment is that the thermal insulation material 7 is a silica fiber-based thermal insulation material. The silica fiber-based thermal insulation material is a fiber material composited with aluminum oxide and silicon dioxide. The addition of aluminum oxide further reduces the thermal conductivity of the fiber, has excellent heat resistance, moisture resistance and mechanical properties, and also enhances the mechanical strength of the fiber.

[0025] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
