Description

Technical Field

[0001] This utility model relates to the field of polyester knitted fabrics, specifically a high heat-absorbing polyester knitted fabric. Background Technology

[0002] With the increasing diversification of people's functional needs for clothing, warm, heat-insulating, and comfortable fabrics have attracted much attention. In cold environments, traditional warm fabrics often rely on thick materials or fillings to reduce heat loss, but this results in bulky clothing that restricts movement. Existing common warm polyester knitted fabrics mainly achieve a certain degree of warmth by increasing fabric thickness and using conventional polyester fiber weaving structures. While they provide some warmth, their effectiveness is limited due to the lack of special heat insulation design and efficient heat absorption mechanisms, and the bulky structure affects wearing comfort and flexibility. Furthermore, for outdoor clothing, warmth alone is insufficient; good heat insulation and sun protection are also necessary to cope with changing environments. Therefore, we propose a high-heat-absorbing polyester knitted fabric to overcome the shortcomings of existing technologies. Through innovative structural design, it achieves a synergistic improvement in multiple performance aspects, including efficient heat absorption, good heat insulation, comfortable wear, and suitable tensile strength.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3A high-heat-absorbing polyester knitted fabric includes an adhesive layer 4, a surface-laminated middle composite layer 3, a surface insulating layer 2, and a surface coating 1. A gap exists between the middle composite layer 3 and the surface insulating layer 2, forming an air layer. Air is a poor conductor of heat, and heat conduction is relatively slow within the air layer, reducing heat transfer. This air layer insulation method is simple and effective, and does not significantly increase the weight or thickness of the fabric, thus enhancing the overall warmth retention.

[0021] Furthermore, surface coating 1 is a metal oxide coating, which is either titanium dioxide or zinc oxide. These metal oxides can reflect some of the infrared rays in sunlight and reduce heat absorption. In outdoor sun protection clothing and other products, this coating can reduce the surface temperature of the fabric and play a role in heat insulation and sun protection. Moreover, these coatings may also have other functions, such as ultraviolet protection.

[0022] Furthermore, the surface barrier layer 2 is composed of multiple polyester fibers interwoven together.

[0023] Furthermore, the bonding layer 4 is made of cotton fibers and graphene fibers interwoven together. The cotton fibers improve moisture absorption, making it more comfortable to wear, while the graphene fibers improve the thermal conductivity in contact with the middle composite layer 3.

[0024] Furthermore, the middle composite layer 3 is woven from multiple sets of composite threads 5. The composite threads 5 include a covering layer 6, an intermediate thread 7, and wound graphene fibers 8. The intermediate thread 7 is located inside the covering layer 6, and the wound graphene fibers 8 are wound on the outside of the covering layer 6. When the wound graphene fibers 8 come into contact with the graphene fibers in the bonding layer 4, they can be quickly conducted to the entire fabric through these graphene fibers, thereby improving the heat absorption efficiency of the fabric and allowing the wearer to feel warmer more quickly in a cold environment. Moreover, between the surface insulating layer 2 and the middle composite layer 3, the wound graphene fibers 8 will form gaps on the surface of the covering layer 6. These gaps are air layers that do not come into contact with the surface insulating layer 2.

[0025] Furthermore, both the covering layer 6 and the intermediate yarn 7 are made of spandex, which has excellent tensile strength. Spandex fibers can return to their original shape even after being stretched to several times their original length. Its good tensile strength ensures that it will not easily break when subjected to various tensile forces generated by human movement. For example, when people wear tight-fitting clothing containing spandex during exercise, such as yoga pants or fitness wear, the spandex fibers can stretch with the body and stably maintain their structural integrity. Spandex fibers are often blended with other fibers for the production of tight-fitting or highly elastic clothing.

[0026] Detailed explanation:

[0027] Surface coating 1 is primarily a metal oxide coating, such as titanium dioxide or zinc oxide. These metal oxides can reflect some of the infrared radiation from sunlight, thereby reducing the fabric's absorption of heat. In outdoor wear scenarios, such as outdoor sun-protective clothing, this coating can effectively reduce the surface temperature of the fabric, providing heat insulation and sun protection.

[0028] In addition to heat insulation and sun protection, the coating may also have other functions such as UV protection, which enables the fabric to provide more comprehensive protection for the wearer in outdoor environments and reduce the damage of ultraviolet rays to the skin.

[0029] The surface insulating layer 2 is composed of multiple polyester fibers interwoven together. This weaving method forms a relatively tight structure, which can isolate the external environment.

[0030] As the first line of defense, it prevents external heat, cold air, dust, etc. from directly contacting the inner composite layer. At the same time, there is a gap between it and the middle composite layer 3, which forms an air layer. The air layer takes advantage of the fact that air is a poor conductor of heat, slowing down heat conduction and enhancing the insulation effect of the fabric.

[0031] The middle composite layer 3 is woven from multiple sets of composite yarns 5. The composite yarn 5 is the basic unit of the middle composite layer 3, and its structure is relatively complex.

[0032] Structure of composite line 5

[0033] Covering layer 6: Made of spandex. Spandex has good tensile strength and can return to its original shape after being stretched to several times its original length. When people wear tight-fitting clothing containing this fabric, such as yoga pants and fitness wear, spandex can stretch with the body and stably maintain its structural integrity without easily breaking, allowing the clothing to conform to the body's movements.

[0034] Intermediate yarn 7: also spandex. Spandex serves as the intermediate yarn in the composite yarn, working together with the covering layer to leverage its tensile strength, enhancing the overall elasticity and tensile strength of the composite yarn, and ensuring the structural stability of the middle composite layer 3 when subjected to tensile forces generated by human movement.

[0035] Graphene fiber 8 is wound around the outside of the covering layer 6. When it comes into contact with the graphene fiber in the bonding layer 4, it forms a good heat conduction channel, quickly transferring heat to the entire fabric and improving the fabric's heat absorption efficiency. In the part that contacts the surface insulating layer 2, the wound graphene fiber forms gaps on the surface of the covering layer 6. These gaps constitute another air layer, further enhancing the heat insulation effect.

[0036] The bonding layer 4 is woven from cotton fibers and graphene fibers in an interlaced pattern.

[0037] The main function of cotton fibers is to enhance the moisture absorption of fabrics, making the wearer feel more comfortable. Especially when the body sweats or is in a humid environment, cotton fibers can absorb and store a certain amount of moisture, keeping the skin dry.

[0038] Graphene fibers are used to enhance the thermal conductivity in contact with the central composite layer 3. When the wound graphene fibers 8 of the central composite layer 3 come into contact with it, they can quickly conduct heat, allowing the wearer to feel warmer more quickly in cold environments.

[0039] This high heat-absorbing polyester knitted fabric achieves efficient heat absorption, good heat insulation, a comfortable wearing experience, and certain elasticity and tensile strength through the synergistic effect between its various structural layers, making it suitable for a variety of outdoor and sportswear applications.
