As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. Different fabrics have different properties such as breathability, moisture absorption, and warmth retention. There are many varieties of existing fabrics, but with the improvement of people's living standards, new varieties that can meet the needs of different groups of people need to be provided. People's requirements for clothing are not only for clothing styles and workmanship, but more for clothing quality.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Embodiment 1, refer to Figure 1 and Figure 2 A warm and cold-resistant fabric and its processing technology, including a fabric body 1, the fabric body 1 is provided with an outer layer, a first wind-blocking layer 3, a second wind-blocking layer 4, a reflective layer 7, a carbon fiber heating film 8, a heat-insulating lining 9, a light-absorbing heating layer 10 and a fabric inner layer 11 from the outside to the inside. The carbon fiber heating film 8 is a common component and can be easily purchased on the market, so it will not be described in detail.

[0036] Example 2, refer to Figure 1 and Figure 2 The outer layer 2 of the fabric is composed of coconut charcoal fiber, which contains coconut charcoal particles. After being made into clothing, it still remains active and has health care effects on the human body, such as activating cells, purifying blood, eliminating fatigue, and improving allergic constitution; the special-shaped three-leaf structure makes the coconut charcoal fiber have a strong adsorption capacity, and the final product has the effect of absorbing and deodorizing chemical gases such as human body odor, oil smoke, toluene, and ammonia; the far-infrared emission rate of coconut charcoal fiber is as high as more than 90%, which can promote blood circulation and improve the human body environment; the coconut charcoal in the fiber forms a porous and water-permeable surface, which can quickly absorb a large amount of moisture, quickly diffuse and volatilize, ensure a dry and breathable effect, and give people a warm and comfortable environment and use feeling.

[0037] Example 3, refer to Figure 1 and Figure 2The first wind-blocking layer 3 and the second wind-blocking layer 4 are both composed of the warp and weft of heat storage mother particle fibers, and a plurality of groups of external ventilation holes 5 and internal ventilation holes 6 are arranged between the warp and weft, and the external ventilation holes 5 and the internal ventilation holes 6 are arranged alternately. The staggered arrangement of the external ventilation holes 5 and the internal ventilation holes 6 is to make the first wind-blocking layer 3 or the second wind-blocking layer 4 passively fit to the wind-blocking layer on the other side through squeezing and wind blowing when the personnel wear the clothes and there is cold wind outside, so that the external ventilation holes 5 can fit on the second wind-blocking layer 4, and the internal ventilation holes 6 can fit on the first wind-blocking layer 3 at the same time. The first wind-blocking layer 3 and the second wind-blocking layer 4 are not aligned together, so the cold air can be effectively blocked at the position of the first wind-blocking layer 3 to prevent the continued invasion of cold air, thereby passively improving the thermal insulation and cold-resistant effect of the fabric. At the same time, the first wind-blocking layer 3 and the second wind-blocking layer 4 are both composed of heat-storage mother particle fibers, and the fiber heat-storage mother particles can efficiently absorb external infrared rays and convert light energy into heat energy. Under light conditions, the temperature of the manufactured fabric can reach more than 15°C. The warming effect is long-lasting and does not decay due to washing, thereby realizing the active heating operation of the outer layer 2 of the fabric and improving the overall cold-resistant quality.

[0038] Embodiment 4, referring to Figure 1 and Figure 2 The reflective layer 7 is composed of calcium carbonate and barium sulfate through chemical vapor deposition. The calcium carbonate particles are good at reflecting visible light and near-infrared wavelengths, while the barium sulfate particles reflect ultraviolet light. This combination enables the coating to effectively reflect the near-infrared light generated when the carbon fiber heating film 8 is heated and used, as well as the natural heat dissipation of the human body, thereby reflecting and removing this part of the heat, reducing the damage caused by overflowing heat, and thus improving the overall thermal insulation effect.

[0039] Example 5, refer to Figure 1 and Figure 2 The thermal insulation lining 9 is made of aerogel insulation material. The thermal insulation lining 9 is provided to prevent the carbon fiber heating film 8 from directly contacting the human skin, resulting in the phenomenon of "low-temperature slow cooking", thereby improving the safety of fabric use and avoiding burns to personnel. The thermal insulation effect can be adjusted by adjusting the thickness of the thermal insulation lining 9, thereby ensuring that the temperature transmitted to the human skin is in the optimal range. The specific thickness can be learned based on personnel experiments, and no further elaboration will be given here.

[0040] Example 6, refer to Figure 1 and Figure 2The light-absorbing and heating layer 10 is composed of volcanic rock (volcanic stone) light-absorbing and heating fibers. The volcanic rock (volcanic stone) fibers contain special volcanic rock (volcanic stone) substances, which have the ability to absorb light waves. When light is irradiated on the volcanic rock (volcanic stone) fibers, the fibers absorb these light waves and convert them into heat energy. This process enables the fibers to generate heat while absorbing light energy, thereby increasing the temperature of the fabric. The mountain rock (volcanic stone) powder has a unique microporous porous structure, which increases its specific surface area for heat absorption and heating. Therefore, the fiber fabric can not only absorb light and generate heat, but also effectively store heat. This characteristic enables the fabric to maintain a high temperature for a long time and provide a lasting warming effect. The volcanic rock (volcanic stone) composite powder is rich in far-infrared ceramic powder. This ingredient can absorb far-infrared light emitted by the human body or the environment and re-emit it. This process helps to improve the thermal insulation performance of clothing because far-infrared rays can penetrate into the skin and promote blood circulation, thereby enhancing the warming effect. In addition to the light-absorbing and heating and warming functions, the volcanic rock (volcanic stone) fibers also have antibacterial and moisture-absorbing and quick-drying properties. The volcanic rock (volcanic stone) )The metal oxides in the composite powder can destroy the molecular structure of the virus and make the virus inactive, thereby giving the fiber antibacterial function. In addition, its porous microporous structure increases the specific surface area for evaporation of water inside the fiber, making the fiber have better moisture absorption and quick-drying functions. In summary, volcanic rock (volcanic stone) light-absorbing and heat-generating fibers absorb light waves and convert them into heat, store and release heat, absorb and emit far infrared rays, and have antibacterial and moisture absorption and quick-drying functions, thus achieving multiple composite functions. This fiber has broad application prospects in the field of clothing and can provide a comfortable wearing experience and multi-functional textile solutions.

[0041] Embodiment 7, reference Figure 1 and Figure 2The inner layer 11 of the fabric is composed of wool fibers and white duck down, and the wool fibers are provided with two layers, and the white duck down is filled between the wool fibers. The wool fibers are connected by yarns, and the yarns are distributed in a rhombus shape. The rhombus-shaped yarns can effectively prevent the fleece from running and avoid the fleece materials from being stacked together. The wool fibers can improve the skin comfort of the fabric, and the white duck down is a common thermal insulation medium. The specific filling amount can be adjusted according to demand, and no further elaboration is made here. In addition to the fiber materials specifically indicated in this application, the other fibers not specifically indicated can be selected according to demand, such as polyester fibers, polyester fibers or cotton fibers, so that the corresponding thermal insulation medium is attached to its surface to ensure the normal use of the structure. Since the coconut charcoal fiber composition and the filling and manufacturing of wool fibers and white duck down are existing mature technologies and are widely used, they are not mentioned in the following process. Personnel can directly purchase the finished structure on the market and cooperate with other structures below to form it. The specific sewing can be achieved by personnel controlling the sewing machine or using an automatic sewing machine. The specific sewing method is not described in detail, and personnel can flexibly adjust it.
