Description

Technical Field

[0001] This utility model belongs to the field of clothing technology, specifically relating to an inner-wear down jacket with a multi-layer down-proof structure. Background Technology

[0002] Down jackets, as the core winter clothing for the cold season, come in a wide variety of styles on the market. However, the main structure of most down jackets on the market currently adopts the traditional three-layer design, consisting of an outer layer, an inner layer, and a down layer filling the space between the two, which are simply connected and fixed by stitching. For example, in the prior art, Chinese patent CN202774209U discloses a down jacket with a scarf-style collar, in which the front, back, sleeves, and collar all include an inner layer, an outer layer, and down filling the space between the inner and outer layers.

[0003] The traditional three-layer stitched structure described above suffers from significant down leakage. Down leakage first and foremost damages the aesthetics of the down jacket. A large amount of down escapes from the seams, resulting in a messy surface and significantly reducing the wearer's overall appearance and the perceived quality of the garment. From a functional perspective, down leakage directly reduces the amount of down filling in the inner insulation layer, compromising the integrity of the insulation structure. This reduces the down jacket's ability to block cold air from penetrating, consequently diminishing its warmth and severely impacting the wearer's comfort in cold environments.

[0004] To address the issue of down leakage, some existing technologies rely on using high-density fabrics as the outer layer of down jackets, attempting to physically block down from escaping by reducing the fabric's pores. However, this approach has significant drawbacks: high-density fabrics often sacrifice breathability. When the wearer is active, sweat cannot be effectively released through the fabric, tending to accumulate inside the garment, causing stuffiness and discomfort, and reducing overall comfort.

[0005] Furthermore, existing down jacket designs primarily focus on outerwear, but the market demand for innerwear down jackets is growing. These products are typically worn as a mid-layer under other outerwear. This necessitates that innerwear down jackets be lightweight, but most existing down jackets are designed to be loose and bulky, creating a noticeable bloated feeling when worn with other outerwear and restricting movement. Moreover, the outer and inner layer fabrics, in pursuit of windproofness, abrasion resistance, or support, are usually quite stiff. When paired with soft outerwear, this can easily create an unpleasant chafing sensation or a bulky appearance, affecting the overall wearing effect and comfort. They are also unsuitable for wearing directly against the skin, as they can easily cause chafing and have poor breathability. Summary of the Invention

[0006] To address the problems in related technologies, this utility model proposes an inner-wear down jacket with a multi-layered down-proof structure to overcome the aforementioned technical issues in existing technologies. The jacket's front and back bodies employ a multi-layered composite structure, with each layer working together to effectively prevent down from escaping and improve down-proof performance. Symmetrical non-down-filled, high-elastic side waist panels are stitched on both sides, conforming to the waistline with elasticity for a natural waist-shaping effect, while remaining lightweight and non-bulky. The first and second lining layers are made of breathable cotton fabric in a single piece, ensuring excellent breathability and reducing stuffiness.

[0007] The technical solution of this utility model is as follows: an inner-wear down jacket with a multi-layer down-proof structure, including a jacket body, the jacket body including a front body and a back body, both of which are multi-layer composite structures.

[0015] On the back of the garment, multiple dividing lines pass sequentially through the third composite fabric layer, the second fleece layer, the fourth composite fabric layer, and the second lining fabric layer, and are connected and fixed to form multiple fleece-filled pouches.

[0016] Furthermore, the first and second down layers are water-repellent down layers. In this invention, the water-repellent down layers are made of water-repellent goose down; wherein, the down content of both the first and second down layers is 10g / m². 2 -30g / m 2 ;

[0017] Preferably, the pile weight distribution of both the first and second pile layers is 10 g / m². 2 -20 g / m 2 .

[0018] Furthermore, the garment body has an antibacterial and deodorizing coating in the armpit area, which is one of a nano-silver antibacterial coating, a nano-titanium dioxide antibacterial coating, or a quaternary ammonium salt antibacterial coating.

[0019] Furthermore, each of the composite fabric layers is a composite structure formed by sequentially stacking and pressing multiple layers of fabric.

[0020] Furthermore, the main body of the garment includes thin shoulder straps that extend from the top of the front of the garment to the top of the back of the garment. At this time, the breathable structure of the back of the garment is open, and the front of the garment includes a chest structure and a down-filled structure that are connected at the top and bottom.

[0021] The first outer fabric layer, the first composite fabric layer, the first fleece layer, the second composite fabric layer, and the first lining fabric layer are sequentially stacked to form the fleece filling structure; the first outer fabric layer and the first lining fabric layer are sequentially stacked to form the chest structure;

[0022] The thin shoulder strap is equipped with a length adjustment buckle.

[0023] The front of the top also has a cup layer inside, which covers the breast structure and has two cup pads inside;

[0024] Furthermore, the top of the cup layer is connected to the top of the breast structure; the bottom of the cup layer extends beyond the bottom of the breast structure, and the bottom of the cup layer is not fixedly connected to the bottom of the breast structure.

[0025] One of the high-elasticity side panels is also equipped with a side zipper.

[0026] Furthermore, the front of the garment is connected to the top of the back of the garment to form a wide shoulder strap.

[0027] Furthermore, the main body of the garment also includes a neckline and long sleeves, and the front and back of the garment are provided with sleeve-connecting portions at the upper end of each of the high-elastic side waist pieces; the two long sleeves are respectively connected to the corresponding sleeve-connecting portions;

[0028] Furthermore, the neckline can be any one of a round neck, square neck, V-neck, or U-neck, with a round neck being preferred in this invention.

[0029] Furthermore, the front of the garment includes a left panel and a right panel in the width direction, and the left panel and the right panel can be detached and connected by a zipper device;

[0030] Furthermore, the zipper device extends from the neckline to the lower part of the front of the garment.

[0031] Furthermore, the neckline is connected to a stand-up collar; or,

[0032] The neckline is connected to a fold-down collar.

[0033] Furthermore, each of the high-elastic side waist pieces forms an arc-shaped seam at the joint with the front and back of the upper garment, and each of the arc-shaped seams extends from the side edge of the sleeve to the lower part of the upper garment body.

[0034] The beneficial effects of this utility model are:

[0035] (1) The front and back of the garment of this utility model are both multi-layer composite structures. The multi-layer composite structures work together to effectively prevent down from coming out from the inside, greatly improving the down-proof performance of the down jacket, extending the service life of the garment, and ensuring warmth and appearance during wear.

[0036] (2) The front and back of the top are symmetrically fitted with high-elastic side waist panels, which are non-down-filled. The high-elastic side waist panels utilize their own elasticity to closely conform to the curves of the human waist, naturally slimming the waist and creating a beautiful body line. At the same time, the non-down-filled design makes the high-elastic side waist panels lightweight and avoids the bulkiness that can occur with down filling, improving the comfort and flexibility of wearing them, making them suitable for a variety of daily activities and sports.

[0037] (3) Both the first and second lining layers are made of breathable cotton fabric, cut and molded in one piece. This breathable cotton fabric has good breathability, allowing the body's heat and moisture to be quickly expelled, reducing stuffiness. At the same time, the breathable cotton fabric is skin-friendly and will not irritate the skin. Furthermore, the back of the top is divided into a breathable structure and a warming structure. This structural division is not a completely closed filling, providing relatively more flexible breathable space for the back compared to a large overall filling. Attached Figure Description

[0058] Example 1

[0059] like Figure 1-4 As shown, this embodiment provides an inner-wear down jacket with a multi-layer down-proof structure, including a jacket body, the jacket body including a front jacket 1 and a back jacket 2, both of which are multi-layer composite structures;

[0060] like Figure 5 As shown, the front of the garment 1 includes a first outer fabric layer 11, a first composite fabric layer 12, a first fleece layer 13, a second composite fabric layer 14, and a first lining fabric layer 15 arranged sequentially from the outside to the inside.

[0061] The back of the garment 2 includes a breathable structure 21 and a heat-insulating structure 22 that are connected at the top and bottom;

[0062] like Figure 4 and Figure 6 As shown, the thermal insulation structure 22 includes, from the outside to the inside, a second outer fabric layer 221, a third composite fabric layer 222, a second fleece layer 223, a fourth composite fabric layer 224, and a second lining fabric layer 225. The breathable structure 21 is formed by overlapping and connecting the second lining fabric layer 225 and the second outer fabric layer 221 in sequence.

[0063] The front body 1 and the back body 2 of the upper garment are symmetrically spliced ​​with high-elastic side waist pieces 3 on the left and right sides, and both of the high-elastic side waist pieces 3 are non-down-filled cut pieces.

[0064] Both the first lining layer 15 and the second lining layer 225 are made of breathable cotton fabric and cut into one piece.

[0065] Specifically, the high-elastic side waist piece 3 is woven from elastic yarn, which includes, but is not limited to, spandex core-spun yarn or elastic polyester yarn.

[0066] Firstly, both the front (1) and back (2) of the jacket feature multi-layered composite structures. These layers work together to effectively prevent down from escaping from the inside out, significantly improving the down-proof performance of the inner-wear down jacket, extending its lifespan, and ensuring warmth and aesthetics during wear. Furthermore, the combination of different composite fabric layers and down layers allows each layer to perform different functions while achieving down-proofing. For example, the outer fabric layer provides basic smoothness (i.e., the down lining is not visible from the outer fabric layer) and some protection, the composite fabric layers enhance structural stability, and the down layer ensures warmth. This rational layout optimizes the inner-wear down jacket's performance in terms of warmth, durability, and other aspects.

[0067] Secondly, the front panel 1 and back panel 2 of the top are symmetrically spliced ​​with high-elastic side waist panels 3, which are non-down-filled. These high-elastic side waist panels 3 utilize their own elasticity to closely conform to the curves of the waist, naturally slimming the waist and creating a beautiful body line, enhancing the wearer's overall image and temperament. At the same time, the non-down-filled design makes the high-elastic side waist panels 3 lightweight, avoiding the bulkiness associated with down filling. The high elasticity ensures that the waist can stretch and bend freely during various activities, greatly improving comfort and flexibility, making it suitable for various daily activities and sports.

[0068] Furthermore, both the first and second lining layers are made of breathable cotton fabric, seamlessly integrated into the design. This breathable cotton fabric offers excellent breathability, allowing body heat and moisture to escape quickly, keeping the body dry and reducing stuffiness and discomfort. It is especially suitable for extended wear or during exercise, enhancing the wearing experience. Simultaneously, the seamless integration process ensures a better fit between the lining layer and the body, eliminating obvious seams and abrupt changes, reducing skin friction and resulting in a softer, more comfortable feel. Moreover, the breathable cotton fabric is skin-friendly and will not irritate the skin, making it suitable for all skin types, especially those with sensitive skin.

[0069] In addition, the back of the garment 2 is divided into a breathable structure 21 and a warming structure 22. This structural division is not a completely closed filling. Compared with a large overall filling, it provides a relatively more flexible breathable space for the back, which helps to expel the heat and moisture generated by the body and improves the breathability of the garment.

[0070] Specifically, both the first lining layer 15 and the second lining layer 225 are provided with multiple dividing lines 4;

[0071] In the front of the upper garment 1, multiple dividing lines 4 pass through the first composite fabric layer 12, the first fleece layer 13, the second composite fabric layer 14 and the first lining layer 15 in sequence and are connected and fixed to form multiple fleece-filled pouches 5 for filling.

[0072] On the back of the upper garment 2, multiple dividing lines 4 pass through the third composite fabric layer 222, the second fleece layer 223, the fourth composite fabric layer 224, and the second lining fabric layer 225 in sequence and are connected and fixed to form multiple fleece-filled pouches 5;

[0073] Specifically, the first down layer 13 and the second down layer 223 are water-repellent down layers. In this embodiment, the water-repellent down layer uses water-repellent goose down; wherein, the down weight distribution of both the first down layer 13 and the second down layer 223 is 10g / m³. 2 -30 g / m 2 ;

[0074] Preferably, the pile weight distribution of both the first pile layer 13 and the second pile layer 223 is 10 g / m². 2 -20 g / m 2 This ensures that the inner down jacket has enough water-repellent goose down to achieve good warmth performance, while avoiding the inner down jacket from being too thick and bulky due to excessive down filling.

[0075] Moreover, the arrangement of the dividing lines 4 and the down filling packs 5 helps to clearly divide the filling area, so that the water-repellent goose down is evenly distributed in each down filling pack 5, avoiding the accumulation or displacement of the water-repellent goose down, and ensuring the stability and uniformity of the warmth retention effect.

[0076] Specifically, the garment body has an antibacterial and deodorizing coating on the underarm area 91. The antibacterial and deodorizing coating is one of nano silver antibacterial coating, nano titanium dioxide antibacterial coating or quaternary ammonium salt antibacterial coating, so as to achieve the effect of antibacterial and deodorizing the underarm area of ​​the human body.

[0077] More specifically, the antibacterial and deodorizing coating has a thickness of 0.04mm-0.11mm and is evenly applied to the inner surface of the armpit area 91.

[0078] Specifically, each of the composite fabric layers is a composite structure formed by stacking and pressing multiple layers of fabric in sequence, which further prevents down from escaping from the inside out and improves the down-proof performance of the inner-wear down jacket.

[0079] Specifically, the main body of the garment also includes a neckline 16 and long sleeves 9. The front body 1 and the back body 2 of the garment are provided with sleeve-connecting parts at the upper end of each of the high-elastic side waist pieces 3. The two long sleeves 9 are respectively connected to the corresponding sleeve-connecting parts.

[0080] More specifically, the long sleeves 9 are also woven from elastic yarn, and both they and the high-elastic side waist pieces 3 are elastic, used to elastically tighten arm fat.

[0081] More specifically, the neckline 16 is set to any one of round neck, square neck, V-neck, and U-neck, with a round neck being preferred in this embodiment;

[0082] The sleeve design allows the down jacket to be used as a warm long-sleeved inner layer, eliminating the need for multiple layers of clothing and enabling people to achieve their warmth needs with fewer layers.

[0083] Specifically, each of the high-elastic side waist pieces 3 forms an arc-shaped seam 31 at the splicing point with the front body 1 and the back body 2 of the upper garment, and each of the arc-shaped seams 31 extends from the side edge of the sleeve to the lower part 10 of the upper garment body.

[0084] When worn, viewed from the front or back of the garment body, the arc-shaped seam 31 presents as a continuous curve protruding towards the outside of the garment body, and this curve configuration visually creates a narrowing effect at the waist.

[0085] Example 2

[0086] like Figure 7-12 As shown, this embodiment also provides an inner-wear down jacket with a multi-layered down-proof structure. Features not explained in this embodiment can be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0087] The main body of the top includes thin shoulder straps 7, which extend from the top of the front body 1 of the top to the top of the back body 2 of the top. At this time, the breathable structure 21 of the back body 2 of the top is open, making the back more breathable.

[0088] At this time, the front body 1 of the upper garment includes a chest structure 72 connected at the top and bottom and a down-filled structure 73, such as Figure 9 As shown; the first outer fabric layer 11, the first composite fabric layer 12, the first fleece layer 13, the second composite fabric layer 14, and the first lining fabric layer 15 are sequentially stacked to form the fleece filling structure 73; the first outer fabric layer 11 and the first lining fabric layer 15 are sequentially stacked to form the chest structure 72;

[0089] like Figure 10 As shown, the front body 1 of the top also has a cup layer 721 inside, which covers the breast structure 72. The cup layer 721 has two cup pads 7211 inside. Because the front body 1 of the top has a cup layer 721, there is no fleece layer at the breast structure 72. Moreover, the cup pads 7211 and the cup layer 721 make it unnecessary for the user to wear an extra bra, thus improving its practicality.

[0090] More specifically, the top of the cup layer 721 is connected to the top of the breast structure 72; the bottom of the cup layer 721 extends beyond the bottom of the breast structure 72, and the bottom of the cup layer 721 is not fixedly connected to the bottom of the breast structure 72.

[0091] like Figure 9 As shown, a side zipper 74 is also provided on one of the high-elastic side waist panels 3 to facilitate the user to put on and take off the upper garment body;

[0092] The thin shoulder strap 7 is provided with a length adjustment buckle 71;

[0093] It should be noted that the thin shoulder straps 7 allow the inner-wear down jacket to be used as a warm tank top, so even if the user wears a sweatshirt or jacket over it, it will not appear bulky; Figure 11-12 As shown, when paired with an off-the-shoulder top, the exposed thin shoulder straps 7 are more aesthetically pleasing and enhance the overall look.

[0094] Example 3

[0095] like Figure 13-14 As shown, this embodiment also provides an inner-wear down jacket with a multi-layered down-proof structure. Features not explained in this embodiment can be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0096] The front of the top 1 is connected to the top of the back of the top 2 to form a wide shoulder strap 6, so that the inner down jacket can be used as a warm wide-strap vest.

[0097] Example 4

[0098] like Figure 15-16 As shown, this embodiment also provides an inner-wear down jacket with a multi-layered down-proof structure. Features not explained in this embodiment can be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0099] The front of the upper garment 1 includes a left garment panel 17 and a right garment panel 18 in the width direction, and the left garment panel 17 and the right garment panel 18 can be detached and connected by a zipper device 8;

[0100] More specifically, the zipper device 8 extends from the neckline 16 to the lower part 10 of the front of the garment 1;

[0101] The zipper device 8 allows the inner-wear down jacket to be used as a thin cardigan worn underneath.

[0102] Specifically, the collar 16 is connected to a stand-up collar; or,

[0103] The collar 16 is connected to a fold-down collar, allowing the inner-wear down jacket to be used as a thermal shirt.

[0104] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
