Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, specifically a heat-balancing and insulating fabric. Background Technology

[0002] As people's living standards continue to improve, their demands for clothing are also increasing. They want clothing that is warm, soft, lightweight, and not bulky. Existing thermal fabrics generally meet these requirements. With the increasing promotion of fitness for all, more and more people enjoy engaging in moderate-intensity physical exercise in the morning or evening. After a certain level of exercise, the body produces sweat; good insulation can actually create a stuffy feeling and reduce comfort. Removing clothing at this time, however, makes it easy to catch a cold, which is detrimental to health. Therefore, the research and development of a fabric that is skin-friendly, warm, and comfortable is particularly important. Utility Model Content

[0003] The purpose of this invention is to provide a thermal insulation fabric that balances heat, is skin-friendly, warm, and increases comfort.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a heat-balancing thermal insulation fabric, characterized in that it includes an outer layer, a middle layer, and an inner layer. The outer layer is knitted from a blended yarn of modified acrylic and viscose fibers from Jilin Chemical Co., Ltd.; the middle layer is knitted from spandex yarn; the inner layer is knitted from a blended cotton and viscose fiber yarn; the blended cotton and viscose fiber yarn contains phase change microcapsules, and a cooling yarn is also woven into the inner layer; the outer surface layer of the outer layer is a napped layer, and the outer surface layer of the inner layer is a brushed layer.

[0005] Preferably, spandex yarns are also woven into the outer layer.

[0006] Furthermore, the linear density and loop length of the Jilin Chemical acrylonitrile viscose fiber modified fiber blended yarn are 13.0 tex and 115 mm / 100 needles, respectively.

[0007] Furthermore, the linear density and loop length of the spandex yarn woven into the outer layer are 2.2 tex and 115 mm / 100 needles, respectively.

[0008] Furthermore, the linear density and loop length of the spandex filament in the middle layer are 3.3 tex and 115 mm / 100 needles, respectively.

[0009] Furthermore, the linear density and loop length of the cotton-viscose fiber blended yarn are 14.8 tex and 320 mm / 100 needles, respectively.

[0010] Furthermore, the transverse and longitudinal densities of the insulation fabric are 41 rows / 25.4mm and 53 rows / 25.4mm, respectively.

[0011] The beneficial effects of this invention are as follows: The outer layer of this fabric is knitted from a blend of Jilin Chemical acrylic viscose fiber and modified fiber yarn. After a napping and heat-pressing process, a napped layer is formed on the outer surface of the outer layer, thereby achieving the warmth and comfort of this fabric. The inner layer of this fabric is knitted from a blend of cotton and viscose fiber yarn. After a brushing process, a brushed layer is formed on the outer surface of the inner layer, making the fabric soft and skin-friendly. The viscose fiber contains phase change microcapsules, which can absorb and store heat when the body temperature rises rapidly, thereby reducing stuffiness. Thermal properties: When the ambient temperature is low, the phase change microcapsules release heat, thereby increasing the temperature of the fabric in contact with the skin. Utilizing the phase change properties of the microcapsules helps maintain a constant skin temperature, thus improving the fabric's wearing comfort. When body temperature rises rapidly, the cooling yarns facilitate the rapid diffusion of body heat, allowing the phase change microcapsules to quickly absorb and store heat, thus increasing the cooling rate. When the ambient temperature drops, the cooling yarns facilitate the rapid diffusion of heat released by the phase change microcapsules, thus quickly keeping the skin warm. The addition of spandex yarns to the outer and middle layers of the fabric gives it elasticity, further enhancing wearing comfort. This fabric possesses warmth, skin-friendliness, and temperature regulation functions, making it suitable for thermal underwear, loungewear, and knee pads. Attached Figure Description

[0015] The following will describe specific embodiments and appendices. Figure 1The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] This invention provides a heat-balancing insulating fabric (such as...) Figure 1As shown, the structure includes an outer layer 1, a middle layer 2, and an inner layer 3. The outer layer 1 is knitted from a blended yarn of Jilin Chemical acrylic-viscose fiber and modified fiber. Jilin Chemical acrylic fiber, viscose fiber, and modified fiber are all known technical products in the textile field. Therefore, the processing of Jilin Chemical acrylic-viscose fiber and modified fiber blended yarn can be achieved using existing yarn blending technology. In this specific embodiment, the proportions of Jilin Chemical acrylic fiber, viscose fiber, and modified fiber in the blended yarn are 50%, 40%, and 10%, respectively. The middle layer 2 is knitted from spandex yarn, which is a known technical product in the textile field. The inner layer 3 is made from a blended yarn of cotton and viscose fiber. Knitted from cotton and viscose fibers, both of which are known technologies in the textile field, the processing of viscose-faced blended yarns can be achieved using existing yarn blending techniques. In this specific embodiment, the proportions of cotton and viscose fibers in the blended yarn are 80% and 20%, respectively. The cotton-viscose blended yarn contains phase change microcapsules. Specifically, a certain amount of phase change microcapsules are added to the viscose fibers. Phase change microcapsules are known and mature technologies in the existing technical field, and they contain a certain amount of phase change material. Utilizing the phase change characteristics of the phase change material, heat absorption and... By utilizing the heat release and absorption properties of the fabric, the phase change microcapsules can achieve temperature regulation, thereby improving the wearing comfort of the fabric products. The temperature regulation process of the phase change microcapsules in the fabric is as follows: when the human body temperature rises rapidly, the phase change microcapsules can absorb and store heat, thereby reducing stuffiness; when the ambient temperature is low, the phase change microcapsules can release heat, thereby increasing the temperature of the fabric in contact with the skin; cooling yarn is also woven into the inner layer 3. The cooling yarn has the function of quickly transferring heat. The combination of cooling yarn and phase change microcapsules can accelerate the phase change process. The microcapsules function as temperature regulators in the fabric. In practical applications, when human skin temperature rises rapidly, the cooling yarn allows for the rapid release of body heat to the phase change microcapsules, enabling the microcapsules to absorb heat quickly and thus achieving a rapid cooling effect on the skin. When the ambient temperature decreases, the phase change microcapsules release heat, and the cooling yarn facilitates the rapid transfer and release of this heat, resulting in a rapid heat retention effect for the inner layer. The outermost layer is a napped layer 11, which provides the fabric with good warmth and softness. The outermost layer of the inner layer 3 is a brushed layer 31, which provides the fabric with good skin-friendliness.

[0017] In practical applications, to improve the elasticity of the fabric and thus enhance the wearing comfort of the fabric products, spandex yarns are also woven into the outer layer 1, based on the above embodiments.

[0018] Based on the above embodiments, the linear density and loop length of the Jilin Chemical acrylonitrile-viscose fiber modified fiber blended yarn are 13.0 tex and 115 mm / 100 stitches, respectively; the linear density and loop length of the spandex yarn woven into the outer layer are 2.2 tex and 115 mm / 100 stitches, respectively; the linear density and loop length of the spandex yarn in the middle layer are 3.3 tex and 115 mm / 100 stitches, respectively; and the linear density and loop length of the cotton-viscose fiber blended yarn are 14.8 tex and 320 mm / 100 stitches, respectively.

[0019] Furthermore, in the actual processing, the fabric's transverse and longitudinal densities are 41 rows / 25.4mm and 53 rows / 25.4mm, respectively.

[0020] In the actual processing of the fabric in this utility model, a WL-SL double-sided circular knitting machine is used to knit a double rib pattern, with a tuck weave added to achieve the fabric textile processing. The WL-SL double-sided circular knitting machine has a gauge of 24 needles / 25.4mm, a tube diameter of 864mm (34 inches), a needle count of 2496×2, and a track count of 72F. Specifically, cotton-viscose blended yarn is threaded into the first and fourth layers with a feed length of 320mm / 100 needles; 50% acrylic-viscose modified fiber blended yarn is threaded into the second and fifth layers with a feed length of 330mm / 100 needles; simultaneously, spandex yarn is inserted into the second and fifth layers with a feed length of 115mm / 100 needles; and spandex yarn is threaded into the third and sixth layers with a feed length of 115mm / 100 needles. During the textile process, the yarn tension of the cotton-viscose fiber blended yarn and the Jilin Chemical acrylic-viscose fiber modified fiber blended yarn is 13CN. The yarn is fed in an active feeding manner, and the number of winding turns is kept to be 20-25 turns as much as possible. The tension of the spandex yarn is controlled within the range of 4-4.5CN.

[0021] In this utility model, "upper", "lower", "front", "back", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as limitations on the scope of protection.

[0022] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0023] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
