Abstract
Description
Technical Field
[0001] This utility model relates to a fabric, specifically an ultra-thin thermal fabric. Background Technology
[0002] Traditional thermal insulation fabrics often rely on increasing material thickness or filling volume to achieve warmth. For example, down jackets are filled with a large amount of down, and cotton-padded jackets rely on multiple layers of cotton wadding to form an insulation layer. However, increased thickness restricts movement when wearing the garment, failing to meet the modern design requirements for lightweight and fitted clothing, and the heavy fabric reduces mobility. The warmth of traditional fabrics largely depends on static air insulation. In humid environments, such as when sweating, cotton fibers easily absorb moisture, leading to a decrease in loft and a significant reduction in insulation performance. Furthermore, they lack active heat generation or dynamic regulation capabilities, making them unsuitable for environments with large temperature differences. Therefore, this application provides an ultra-thin thermal insulation fabric. Utility Model Content
[0003] The purpose of this invention is to provide an ultra-thin thermal fabric that, while maintaining a lightweight body, still provides good warmth retention and also has far-infrared emission capabilities.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: an ultra-thin thermal fabric, comprising: a fabric body, wherein the fabric body is woven from two guide bars, GB1 and GB2; the padding yarn numbers and threading methods of GB1 and GB2 are as follows:
[0005] GB1: 1-0 / 1-2 / 2-3 / 2-1 / / Full penetration;
[0006] GB2: 1-0 / 1-2 / 2-3 / 2-1 / / Full penetration;
[0007] The GB1 fabric incorporates far-infrared warming yarn, while the GB2 fabric incorporates antibacterial warming yarn; the surface density of the main body of the fabric is 120-180 g / m².
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the far-infrared warming yarn is a rabbit hair graphene viscose blended yarn.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial and warm yarn is an antibacterial and warm core-wrapped composite yarn.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial and warm yarn is a cotton-copper alginate fiber blended yarn.
[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the areal density of the main body of the fabric is 160g / ㎡.
[0012] The beneficial effects of this utility model are as follows: Based on the ultra-thin thermal fabric of this utility model, compared with traditional thick thermal fabrics, the weight and thickness are greatly reduced, achieving an ultra-thin effect. Through the synergistic effect of far-infrared thermal yarn and antibacterial thermal yarn, it breaks through the traditional thermal insulation logic of fabrics that rely on thickness or filling amount. Under the condition that the main body of the fabric is lightweight, it still has a good thermal insulation effect. In addition, the far-infrared thermal yarn also has a far-infrared emission function, emitting far-infrared rays that can be absorbed by the human body and converted into heat energy, realizing active heating and warmth. Attached Figure Description
[0013] Figure 1 This is a diagram showing the movement of the yarn padding in GB1 and GB2 as described in this utility model. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0015] Example 1
[0016] Combination Figure 1 This embodiment provides a detailed description of an ultra-thin thermal fabric, comprising: a main fabric body, which is woven from two guide bars, GB1 and GB2; the padding yarn numbers and threading methods of GB1 and GB2 are as follows:
[0017] GB1: 1-0 / 1-2 / 2-3 / 2-1 / / Full penetration;
[0018] GB2: 1-0 / 1-2 / 2-3 / 2-1 / / Full penetration;
[0019] The GB1 structure incorporates far-infrared insulating yarn, while the GB2 structure incorporates antibacterial insulating yarn; the areal density of the main fabric component is 120-180 g / m². Specifically, in this embodiment, the areal density of the main fabric component is 160 g / m².
[0020] Compared to traditional heavy and warm fabrics, the main body of this fabric is significantly lighter and thinner, achieving an ultra-thin effect that meets the modern clothing design requirements for lightweight and slim fit, improving ease of movement while wearing. Through the synergistic effect of far-infrared and antibacterial warming yarns, it breaks through the traditional logic of relying on thickness or filler volume for warmth. While maintaining a lightweight main body, it still offers good warmth retention. Furthermore, the far-infrared warming yarns also have far-infrared emission capabilities, emitting far-infrared rays that can be absorbed by the human body and converted into heat energy, achieving active heating and warmth retention. GB1 and GB2, as the front and back combs, adopt a co-directional knitting structure, resulting in warp-knitted fabrics that can be freely cut and are not easily unraveled.
[0021] Furthermore, the far-infrared warming yarn is a rabbit hair graphene viscose blended yarn. Specifically, the rabbit hair graphene viscose blended yarn is made by blending rabbit hair fibers and graphene viscose fibers in a 60:40 ratio. Rabbit hair is a natural animal fiber, known for its whiteness, softness, smoothness, and excellent warmth retention, breathability, and moisture absorption. Graphene viscose fibers are prepared by blending graphene with viscose spinning solution, exhibiting good performance in far-infrared emission and antibacterial properties. The far-infrared emission performance of the rabbit hair graphene viscose blended yarn is excellent. Graphene itself is a high-emissivity far-infrared material, emitting far-infrared waves in the 4.0-14.0μm range. These far-infrared radiation waves are absorbed by the human body, providing health benefits. In addition, rabbit hair fibers have excellent warmth retention properties, and graphene, by radiating far-infrared light waves, increases its energy and also possesses warmth retention properties.
[0022] Furthermore, the antibacterial and warm yarn is an antibacterial and warm core-spun and wrapped composite yarn. This antibacterial and warm core-spun and wrapped composite yarn consists of a yarn core, outer short fibers, and outer filaments. The yarn surface is covered with regularly spaced filaments, making the yarn less prone to disintegration and slippage, thus improving abrasion resistance. The yarn core is a 44.4 dtex / 24F antibacterial polyester filament, the outer short fibers are Anteibe / Nuan Yirong (a blend of 50 / 50), and the wrapping yarn is a 77.8 dtex / 36F graphene filament. Anteibe is a modified viscose fiber with antibacterial properties; Nuan Yirong is a modified polyester with moisture-wicking, heat-retaining, and microcirculation-improving characteristics, offering good antibacterial and skin-protecting effects; and the graphene filament is a composite filament with antibacterial far-infrared and UV-protective properties. Utilizing graphene modification technology, it reduces far-infrared loss, maximizing temperature rise and providing heat retention and warmth.
[0023] Example 2
[0024] The difference from Example 1 is that the antibacterial and warm yarn is a cotton-copper alginate fiber blended yarn. Specifically, the cotton-copper alginate fiber blended yarn is a 50 / 50 cotton / copper alginate fiber blend. Copper alginate fiber is an alginate fiber produced by wet spinning through a series of ion exchanges between sodium alginate and copper ions. It has good antibacterial properties against both Gram-negative and Gram-positive bacteria. The cotton-copper alginate fiber blended yarn exhibits good antibacterial and bacteriostatic functions against Escherichia coli, Staphylococcus aureus, and Candida albicans, with an infrared irradiation heating rate of 0.214℃ / s, demonstrating good warmth retention performance.
[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
