Description

Technical Field

[0001] This utility model relates to the field of clothing fabric technology, and more specifically, to a down jacket heat insulation fabric. Background Technology

[0002] With the continuous improvement of living standards, consumers' demand for winter down jackets is increasing. At the same time, higher requirements are being placed on the lightweight, comfort, and functionality of clothing. Down jackets have also evolved from traditionally relying on animal and plant fibers for insulation to incorporating various new chemical fibers, such as polyimide fibers, polyphenylene sulfide fibers, graphene fibers, and aerogel particles. While inorganic fiber materials offer better insulation performance, they are more brittle than organic fibers, with lower resilience and elongation, and are more difficult to process, making them less suitable for use in clothing fabrics.

[0003] Traditional down jackets mainly rely on animal fibers (such as duck down and goose down) and plant fibers (such as cotton fiber) as insulation materials. Although they have certain warmth retention properties, they still have the following technical problems in actual use. The insulation performance of traditional down jackets mainly depends on the thickness and density of the filling material, which makes the garments heavy and not lightweight enough, making it difficult to meet the needs of modern consumers for lightweight clothing. In view of this, we propose a down jacket insulation fabric. Utility Model Content

[0004] The purpose of this invention is to provide a heat-insulating fabric for down jackets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A down jacket insulation fabric includes an outer layer, and an insulation layer, a down middle layer, and a skin-friendly inner layer are sequentially arranged on the inner side of the outer layer; the outer layer, the insulation layer, and the skin-friendly inner layer are fixed by sewing, and the down middle layer is located between the insulation layer and the skin-friendly inner layer, and the down middle layer is filled with animal, plant and chemical fibers.

[0007] Preferably, the insulation layer is woven from multiple sets of warp and weft threads, with four warp threads forming a set and the weft threads including a first weft thread and a second weft thread.

[0008] Preferably, the four warp threads in a set are in the following order: polyester a, polyimide fiber b, polyimide fiber b, and polyester a.

[0009] The first weft is polyester (c), and the second weft is cotton fiber (d).

[0010] Preferably, the outer layer is woven from polyester or polyimide fibers.

[0011] Preferably, the heat insulation layer is made by impregnating a zirconium oxide solution and then naturally drying it.

[0012] Preferably, the skin-friendly inner layer is made of spandex and cotton fibers.

[0013] Preferably, the filling material of the down middle layer is duck down, goose down, cotton staple fiber, or polyimide staple fiber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a multi-layered structural design, particularly the combination of an insulation layer and a down-filled interlayer, to effectively insulate against cold air and lock in body heat, providing superior warmth. The insulation layer employs a special weaving process and zirconium oxide solution treatment, further enhancing its insulation performance. The skin-friendly inner layer is made of spandex and cotton fibers, offering softness, breathability, and a close fit to the skin, improving comfort and health, and making it suitable for extended wear. The outer layer is woven from polyester and polyimide fibers, possessing abrasion-resistant, tear-resistant, windproof, and waterproof properties, enhancing the fabric's durability and practicality, making it suitable for various outdoor environments.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example:

[0021] Please see Figure 1 A down jacket insulation fabric includes an outer layer 2, characterized in that: an insulation layer 3, a down middle layer 4, and a skin-friendly inner layer 5 are sequentially disposed on the inner side of the outer layer 2; the outer layer 2, the insulation layer 3, and the skin-friendly inner layer 5 are fixed together by sewing, and the down middle layer 4 is located between the insulation layer 3 and the skin-friendly inner layer 5. The down middle layer 4 is filled with animal, plant, and chemical fibers.

[0022] The insulation layer 3 is made by impregnating the fabric with a zirconium oxide solution and then naturally drying it. Zirconia fiber has excellent thermal insulation properties, as well as high strength and modulus, and a certain degree of flexibility. It can be composited onto fabric using a solution impregnation method, a simple processing technique. When used as an outer fabric layer, zirconium oxide fiber provides excellent thermal insulation and corrosion resistance to down jackets. Zirconia fiber exhibits excellent chemical stability and corrosion resistance, resisting erosion from humid, acidic, alkaline environments and ultraviolet radiation. Through zirconium oxide solution impregnation, the corrosion resistance and durability of the insulation layer 3 are significantly improved, extending the service life of the down jacket.

[0023] In this application, the heat insulation layer 3 is woven from multiple sets of warp and weft threads. Each set consists of four warp threads, and the weft threads include a first weft and a second weft. The order of the four warp threads in a set is polyester a, polyimide fiber b, polyimide fiber b, and polyester a; the first weft is polyester c, and the second weft is cotton fiber d. The heat insulation layer further enhances its heat insulation performance through weaving and zirconium oxide solution treatment. The weaving structure uses a symmetrical warp arrangement (abba), with the polyimide fiber in the center to reduce heat conduction through the thickness direction. Polyester a protects the polyimide fiber from mechanical damage (such as scratches and impacts). The weft threads are alternately woven (polyester c + cotton fiber d). Polyester c: when densely woven, enhances tear resistance; when loosely woven, improves flexibility. Cotton fiber d: intermittent insertion improves breathability while avoiding the stiffness of pure synthetic fibers.

[0024] In this application, the outer layer 2 is woven from polyester and polyimide fibers, which has the characteristics of being abrasion resistant, tear resistant and windproof and waterproof, enhancing the durability and practicality of the fabric and making it suitable for a variety of outdoor environments.

[0025] In this application, the skin-friendly inner layer 5 is made of spandex and cotton fibers, which is soft, breathable, and conforms to the skin, improving the comfort and health of wearing it, and making it suitable for long-term wear.

[0026] In this application, the filling material of the down middle layer 4 is duck down, goose down, cotton staple fiber, and polyimide staple fiber, which not only ensures warmth but also reduces the overall weight, making it light and comfortable to wear.
