Description

Technical Field

[0001] This utility model relates to the field of clothing technology, and more specifically to a multi-layered thermal sweater. Background Technology

[0002] As an essential garment for daily wear and warmth, sweaters not only need to meet the need for warmth, but also need to pay attention to the design, appearance and comfort.

[0003] In existing technology, the most common way to prevent cold air from entering through the hem of a sweater is to install a loop elastic band at the hem. This elastic band uses its own elastic contraction force to tighten the hem of the sweater, thus keeping the hem close to the wearer's waist and abdomen. This method has the following drawbacks: 1. The ring-shaped elastic band generates an inward contraction force throughout the waist, causing the sweater fabric to become redundant and piled up in the abdominal area due to the forced binding, forming a local bulge in the sweater in that area. This makes the area appear abnormally large and bulky, directly affecting the overall visual aesthetics and failing to meet consumers' pursuit of a slim and neat appearance. 2. Due to the stacking of fabric in the abdominal area of ​​the sweater, the sweater lacks support and cannot maintain a flat and upright shape, so this needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-layered thermal sweater.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-layered thermal sweater includes: a sweater body, the sweater body including a front piece and a back piece, the front piece and the back piece having a connecting structure corresponding to the waist area of ​​the human body and forming a sandwich layer through the connecting structure, the sandwich layer having at least one drawstring, the drawstring being fixed to both sides of the sandwich layer, and the drawstring being used to pull the waist area of ​​the sweater body inward. Both the front piece and the back piece include an inner cotton layer, a windproof layer, and an outer cotton layer stacked sequentially from the inside out. The windproof layer is made of woven fabric, and the inner cotton layer, the windproof layer, and the outer cotton layer are fixedly connected by quilting thread.

[0006] As a further improvement of this utility model, the connecting structure consists of a front connecting piece and a rear connecting piece, with the front connecting piece and the rear connecting piece integrally connected to each other on both sides, and the interlayer being a channel formed between the front connecting piece and the rear connecting piece.

[0007] As a further improvement of this utility model, the upper end of the gathering strap forms a U-shaped structure towards the inner side of the sweater body, the U-shaped structure is fixedly connected to the sweater body by quilting thread, and the front connecting piece is fixed to the gathering strap.

[0008] As a further improvement of this utility model, a suture line is provided at the center of the front connecting band, the suture line extends vertically, and the front connecting band is sutured and fixed to the front connecting piece through the suture line.

[0009] As a further improvement of this utility model, the color difference value ΔE between the suture and the front connecting piece is ≥5.0.

[0010] As a further improvement of this utility model, the gathering band is an elastic woven band.

[0011] As a further improvement of this utility model, the width of the gathering band gradually increases from the upper end to the lower end of the sweater body.

[0012] The beneficial effects of this utility model are: 1. By combining the drawstring hidden in the interlayer with the U-shaped fixing structure, the waist is directionally and three-dimensionally gathered, effectively avoiding the fabric accumulation and bulkiness caused by traditional ring elastic bands in the abdomen, making the sweater fit the human body curves better and look crisp and neat.

[0013] 2. The woven windproof layer provides excellent windproof and warmth retention while also giving the front and back panels a crisp and sturdy feel. Together with the drawstring, this ensures that the sweater maintains a flat and upright shape, resulting in a high-quality texture. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0017] like Figure 1-2 As shown, this embodiment provides a multi-layered thermal sweater, including a sweater body 1, which is formed by sewing a front piece 2 and a back piece 3 together at the shoulder and side seams.

[0018] Furthermore, the front piece 2 and the back piece 3 are provided with connecting structures in the areas corresponding to the waist of the human body. In this embodiment, the connecting structures are specifically a front connecting piece 9 and a back connecting piece 10. The left and right edges of the front connecting piece 9 are integrally connected and fixed to the front piece 2 by quilting; similarly, the left and right edges of the back connecting piece 10 are also integrally connected and fixed to the back piece 3 by quilting. Moreover, the upper sides of the front connecting piece 9 and the back connecting piece 10 are aligned with and sewn to the side seam of the sweater body 1, and the lower sides of the front connecting piece 9 and the back connecting piece 10 are sewn together. Thus, in the waist area of ​​the front piece 2 and the back piece 3, the front connecting piece 9, the back connecting piece 10, and the gap between them together form a sandwich layer 4.

[0019] Preferably, both the front piece 2 and the back piece 3 include, from the inside out, an inner cotton layer 6, a windproof layer 7, and an outer cotton layer 8, which are stacked sequentially.

[0020] The inner cotton layer 6 and the outer cotton layer 8 are preferably made of knitted cotton to ensure skin-friendly comfort and warmth.

[0021] The windproof layer 7 is made using a woven process, such as a dense nylon or polyester fabric, to effectively block cold air penetration. The inner cotton layer 6, the windproof layer 7, and the outer cotton layer 8 are fixedly connected by multiple quilted seams. These quilted seams can form diamond, wave, or other geometric patterns, which not only prevent the filling material from shifting but also increase the aesthetics of the garment. At the same time, placing the woven windproof layer 7 between the inner cotton layer 6 and the outer cotton layer 8 gives the front piece 2 and the back piece 3 a stronger sense of support, thereby improving the overall flatness and crispness of the sweater body 1 and enhancing its overall aesthetics.

[0022] Furthermore, a drawstring 5 is provided within the interlayer 4. The drawstring 5 is preferably an elastic woven tape with good resilience. The two ends of the drawstring 5 are respectively fixed to the two sides of the interlayer 4. Specifically, the ends of the drawstring 5 can be sewn in and fixed together when the front piece 2 and the back piece 3 are sewn together.

[0023] The upper edge of the drawstring 5 is bent inward toward the inside of the sweater body 1 to form a U-shaped structure 11. The U-shaped structure 11 is firmly sewn to the sweater body 1 by quilting. At the same time, the middle part of the drawstring 5 is fixed to the inside of the front connecting piece 9 by gluing or sewing.

[0024] Due to the U-shaped structure 11, the gathering band 5 can obtain a gathering force in a clear direction. Thus, when the gathering band 5 is gathered, it can stably drive the edges of the front piece 2 and the rear piece 3 to gather towards the inside of the body, thereby avoiding accumulation on the outside of the body and ensuring the overall uprightness of the body.

[0025] Furthermore, the width of the gather band 55 gradually increases from the upper end to the lower end of the sweater body 11. Specifically, the gather band 55 is narrower near the upper end under the armpit, providing a gentler gathering force; while it is wider near the lower end of the hip bone, providing stronger and more stable support and gathering force. This gradient width design better conforms to the force distribution of the human waist, further improving wearing comfort and shaping effect, making the hem of the sweater fit the body more closely and preventing it from slipping up.

[0026] Furthermore, at the center of the front connecting piece 9, there is a vertically extending suture line 12. This suture line 12 sutures and fixes the middle part of the front connecting piece 9 to the lower structure. Its function is to provide an additional fixing point so that when the tightening band 5 is under force, it can more accurately pull the central area of ​​the waist of the front piece 2 inward to form a more ergonomic curved surface and avoid irregular wrinkles.

[0027] To enhance aesthetics, the stitching color used for the seam 12 is significantly different from the fabric color of the front connecting piece 9, with a color difference value ΔE ≥ 5.0. This design makes the seam 12 a striking decorative element, enhancing the product's recognizability and design appeal.

[0028] When in use, the user wears the sweater body 1, and the drawstring 5 is in a slightly stretched or ready-to-stretch state in its natural state. In this state, the elasticity of the drawstring 5 will cause the front connecting piece 9 to be drawn inward to the sweater body 1, and further pull the front piece 2 and the back piece 3 to be drawn inward to both sides, thereby achieving directional drawing and avoiding the accumulation of the sweater body 1 fabric at the waist and abdomen, giving a tall and upright visual effect. At the same time, the drawing of the drawstring 5 makes the fabric more close to the body, thereby improving the slimming effect. In addition, the drawing effect of the drawstring 5 can also reduce the entry of cold air, thereby improving the cold protection and warmth.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
