Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a heat-retaining and warm jacquard fabric. Background Technology

[0002] Currently, heating fabrics on the market mainly achieve their heating effect by adding functional components such as graphene, carbon fiber, and phase change materials. However, existing technologies have the following shortcomings: First, the functional components have poor bonding stability with the fabric fibers, and their heating performance decreases significantly after repeated washing. Second, some heating fabrics sacrifice the softness and elasticity of the fabric to achieve the heating function, resulting in a poor wearing or usage experience. Third, traditional multi-layered fabrics often use a layered bonding process, which is prone to delamination and wrinkling problems, and the design of the gaps between layers is unreasonable, affecting heat retention and functional synergy.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a heat-retaining and heat-insulating jacquard fabric for improving the heat retention performance of fabrics.

[0005] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a heat-retaining and warm jacquard fabric, comprising a fabric body, characterized in that: the fabric body comprises a surface layer, a connecting layer, a heat-retaining layer, and a skin-friendly layer; the connecting layer comprises a plurality of continuously and evenly distributed first connecting lines, one end of which is connected to the skin-friendly layer and the other end of which is connected to the surface layer, the length of which is 2-5mm, and the connecting layer forms a heat-retaining space between the skin-friendly layer and the surface layer; the heat-retaining layer is composed of a plurality of evenly distributed pile yarns, one end of which is fixed to the skin-friendly layer and the other end of which extends toward the surface layer, the length of which is not shorter than the length of the first connecting lines, and the pile yarns fill the heat-retaining space.

[0006] A further improvement is that the first connecting line is alternately hooked onto the lower surface of the surface layer and the upper surface of the skin-friendly layer.

[0007] A further improvement is that the first connecting line is stitched through the surface layer and the skin-friendly layer.

[0008] A further improvement is that the connecting layer also includes a second connecting line, which forms the sewing trajectory line of the compression heat storage space by sewing along the transverse and longitudinal spacing respectively.

[0009] A further improvement is that the surface layer is knitted from a first yarn and a second yarn; and the skin-friendly layer is knitted from a second yarn and a third yarn.

[0010] A further improvement is that the first yarn is a wool blend yarn.

[0011] A further improvement is that the second yarn is an elastic-covered yarn.

[0012] A further improvement is that the third yarn is a polyester fiber filament yarn.

[0013] A further improvement is that the polyester fiber filament yarn of the third yarn forms the pile yarn of the heat storage layer facing the surface layer.

[0014] A further improvement is that the length of the first connecting line is 2mm, 3mm, or 5mm.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are: 1. Existing thermal fabrics mostly rely on functional coatings to achieve warmth, but the performance of these coatings diminishes after washing. This design abandons the traditional "fiber + additives" model, relying instead on the structure and yarn characteristics to achieve heat retention. The heat-retaining layer's fleece yarn is integrally molded with the skin-friendly layer, fully absorbing heat from the skin-friendly layer and storing it within the heat-retaining space. Even after multiple washes, it maintains stable heat retention performance without significant degradation. Furthermore, a highly efficient heat-retaining system is constructed through a "connecting layer + heat-retaining layer." The connecting layer separates the surface layer from the skin-friendly bottom layer, creating a heat-retaining space that traps hot air. The fleece yarn of the heat-retaining layer fully fills this space, forming an air gap to prevent heat diffusion. The skin-friendly layer adheres to the skin, fully absorbing body heat and transferring it to the heat-retaining layer, achieving long-lasting warmth—superior to traditional single-layer heat-generating fabrics. The surface layer contains wool fibers, further locking in heat, reducing heat loss, and improving the fabric's warmth retention.

[0016] 2. Existing thermal insulation fabrics mostly rely on functional coatings to achieve warmth. These coatings increase the fabric's stiffness, sacrificing comfort. This design, however, balances functionality and comfort through a scientific yarn combination and design. The outer layer uses a combination of wool blend yarn and elastic covered yarn in a knitted pattern, resulting in a delicate touch and resistance to stiffness. The elastic covered yarn incorporates elastic components, giving the fabric good stretch and allowing it to conform to different body shapes without feeling tight.

[0017] 3. Traditional multi-layered fabrics often rely on bonding processes, which are prone to delamination and wrinkling, affecting appearance and function. In this case, the connecting layer uses a yarn bonding process to firmly connect the layers, rather than traditional glue bonding, resulting in strong interlayer bonding and effectively preventing delamination. At the same time, the horizontal and vertical stitching lines can fix the position of each layer for a second time, preventing the first connecting line from breaking during washing or use, which helps the fabric maintain a good appearance for a long time.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] refer to Figure 1 , Figure 2 This utility model discloses a heat-retaining and warm jacquard fabric, including a fabric body 10, which includes a surface layer 11, a connecting layer 12, a heat-retaining layer 13, and a skin-friendly layer 14. The surface layer 11 is a knitted jacquard surface layer 11. The connecting layer 12 includes a plurality of continuously and evenly distributed first connecting lines 15, one end of which is connected to the skin-friendly layer 14 and the other end to the surface layer 11. The length of the first connecting lines 15 is 2-5mm, selected according to the fabric thickness, and preferably 2mm, 3mm, or 5mm. The connecting layer 12 forms a heat-retaining space 16 between the skin-friendly layer 14 and the surface layer 11. The first connecting lines 15 are formed by sewing yarn through the surface layer 11 and the skin-friendly layer 14. The connecting layer 12 also includes second connecting lines 17, which are sewn along the transverse and longitudinal spacing to form the sewing trajectory lines for compressing the heat-retaining space 16.

[0023] The heat storage layer 13 is located within the heat storage space 16 of the connecting layer 12. The heat storage layer 13 is composed of a plurality of evenly distributed pile yarns 18. One end of each pile yarn 18 is fixed to the skin-friendly layer 14, and the other end extends towards the surface layer 11. The length of each pile yarn 18 is not shorter than the length of the first connecting line 15. The pile yarns 18 fill the heat storage space 16. The connecting layer 12 provides a fluffy space for the heat storage layer 13, which is conducive to the pile yarns 18 retaining hot air and locking in heat.

[0024] The first yarn is a wool blend yarn, and the second yarn is an elastic covered yarn made of high-count viscose-covered spandex. The third yarn is a polyester filament yarn. The surface layer 11 is knitted from the first and second yarns. The skin-friendly layer 14 is knitted from the second and third yarns, with the polyester filament yarn of the third yarn forming the pile yarn 18 of the heat storage layer 13 facing the surface layer 11. That is, the side of the skin-friendly layer 14 away from the skin is sheared to form the pile yarn, while the inner surface of the skin-friendly layer 14 is smooth. The addition of spandex gives the fabric elasticity, allowing the inner surface of the skin-friendly layer 14 to conform to the skin, absorbing heat through full contact with the skin and transferring and storing the heat in the fluffy heat storage layer 13 between the skin-friendly layer 14 and the surface layer 11.

[0025] Based on the aforementioned technical solutions, such as Figure 3 The first connecting line 15 can also be continuously and alternately hooked onto the lower surface of the surface layer 11 and the upper surface of the skin-friendly layer 14 to form a connecting layer 12.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
