Description

Technical Field

[0001] This utility model belongs to the field of clothing technology, specifically relating to a slim-fitting, breathable, water-repellent down T-shirt. Background Technology

[0002] Down jackets are garments designed for warmth. For example, Chinese patent CN214103253U discloses a side-opening down vest. This vest includes a front and a back panel, with elastic drawstrings sewn together on both panels. A buckle is movably connected to the end of the elastic drawstring away from the front and back panels, and the buckles on the front and back panels engage with each other. This design is suitable for elderly people with limited joint flexibility for daily warmth. However, with rising living standards and changing consumption habits, consumers' demands for down jackets have expanded from basic warmth to include comfort, aesthetics, and functionality.

[0003] However, in practical applications, existing down jackets still have the following drawbacks:

[0004] When the human body moves, the back is one of the main areas for heat dissipation, and it has less friction with clothing and poor air circulation. The common method of filling the back of down jackets is to fill it with down evenly all over, which can ensure warmth, but it also hinders air circulation. This causes moisture to accumulate when the body sweats, resulting in stuffiness and dampness, reducing wearing comfort, and may even cause skin irritation.

[0005] In terms of design, traditional down jackets, in order to achieve sufficient warmth, typically adopt a relatively loose fit and do not fully consider the curves of the human body when filling with down. This results in a bulky appearance that lacks aesthetics and style. Especially at the waist, the lack of a proper waist-cinching design means the down jacket cannot conform to the body's curves, further exacerbating the bulky look. This bulky design not only affects the wearer's appearance but also restricts freedom of movement. Moreover, current down jackets are only suitable as the outermost layer; wearing them underneath only makes them appear bulkier and exacerbates the feeling of stuffiness due to poor breathability.

[0006] Furthermore, most down jackets currently use hydrophilic down as their core filling material, which tends to clump after washing. During washing and drying, the down feathers stick together due to the moisture, forming clumps of varying sizes. These clumps not only affect the smoothness of the down jacket's appearance but also cause uneven warmth, significantly reducing the insulation in certain areas. Moreover, washed down requires a long drying time, and if it is not thoroughly dried, bacteria and mold can easily grow inside, producing unpleasant odors and even affecting the wearer's health. Summary of the Invention

[0007] In view of the problems in the related art, the present utility model proposes a figure - flattering, breathable and water - repellent down T - shirt to overcome the above - mentioned technical problems existing in the existing related art.

[0021] Furthermore, the second inner layer is also sewn with a first pleat and a second pleat.

[0022] Both the first inner layer and the second inner layer are made of breathable cotton fabric cut and molded in one piece;

[0023] Both the first and second surface layers are woven from polyester fiber yarn, cotton yarn, and spandex yarn;

[0024] The single-layer elastic woven structure is woven from highly elastic yarns, including but not limited to spandex core-spun yarns or elastic polyester filaments.

[0025] Furthermore, the side waist seam and the skin-contact side of the sleeve are both provided with fleece, and the skin-contact sides of the first inner layer and the second inner layer are also provided with fleece.

[0026] Furthermore, the hydrophobic and warming material is water-repellent down, and in this utility model, the water-repellent down is preferably selected as water-repellent goose down;

[0028] Furthermore, the collar of the garment body and the cuffs of the sleeves are provided with elastic ribbed structures, which are woven from cotton and spandex blend yarns.

[0029] The surface of the elastic ribbed structure is provided with a protective coating, which is one of the following: a single-component nanocomposite coating, an ultra-dirty nanocoating, a nano-titanium dioxide composite coating, or a modified nanoparticle-reinforced organosilicon coating.

[0030] Furthermore, the neckline can be any one of a round neck, square neck, or V-neck, with a round neck being the preferred choice in this invention.

[0031] Furthermore, each of the side waist seams forms an arc-shaped waist-cinching seam at the junction with the front and back panels, and each of the arc-shaped waist-cinching seams extends from the side edge of the armhole to the hem of the garment body.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0052] like Figure 1-4As shown, this embodiment provides a slim-fitting, breathable, water-repellent down T-shirt, including a garment body. The garment body includes a front panel 1, a back panel 2, two side waist seams 7, and two sleeves 8. The tops of the front panel 1 and the back panel 2 are connected to form a shoulder 3. The left and right sides of the front panel 1 are respectively connected to the left and right sides of the back panel 2 through the corresponding side waist seams 7, and each side waist seam 7 of the front panel 1 and the back panel 2 has an armhole at its upper end. The two sleeves 8 are respectively connected to the corresponding armholes.

[0053] Both the side waist seam 7 and the sleeve 8 are single-layer elastic knitted structures;

[0054] The front panel 1 is provided with a first down filling area 11, and the back panel 2 includes an upper back 21 and a second down filling area 22 arranged on the top and bottom respectively; both the first and second down filling areas are filled with hydrophobic and warm insulation material; and the elasticity of the first and second down filling areas is less than that of the side waist seam 7 and the sleeve 8.

[0055] First, the single-layer elastic weave structure gives the side waist seam 7 elastic deformation capability, so the side waist seam 7 can elastically adapt to the wearer's side waist contour, while providing a certain amount of shrinkage force, so as to achieve a slimming effect that fits the side waist and improves the user's convenience in putting on and taking off the garment.

[0056] Secondly, the sleeve 8 also adopts a single-layer elastic knit structure, which can adapt to arm movements. While ensuring free movement, it fits the contour of the arm, so that the sleeve 8 can also achieve the effect of shrinking arm fat, further improving the overall appearance of the garment.

[0057] Moreover, both the first down filling area 11 and the second down filling area 22 are filled with hydrophobic insulating material. The hydrophobic properties make the material less likely to absorb a large amount of water during the washing process, reducing the possibility of material fibers sticking together due to water intrusion. This effectively avoids clumping after washing, maintains the fluffy state and warmth retention performance of the hydrophobic insulating material, and thus extends the service life of the water-repellent down T-shirt.

[0058] Finally, the back panel 2 features an upper back 21 and a second down-filled area 22. This structural division is not a completely closed filling; compared to a large overall filling area, it provides a more flexible breathable space for the back, helping to expel body heat and moisture and improving the breathability of the garment. Simultaneously, the design of the side waist seam 7 and sleeves 8 also contributes to improved breathability at the sides and arms.

[0059] Specifically, the front panel 1 includes, from the outside to the inside, a first outer layer, a first down filling layer, and a first inner layer; multiple pleats are sewn on the first inner layer, and the multiple pleats pass through the first down filling layer and the first inner layer in sequence and are connected and fixed to form multiple down grids 6 for filling;

[0060] Specifically, a first pleat line 4 and a second pleat line 5 are sewn on the first inner layer, and a plurality of the first pleat lines 4 and the second pleat lines 5 are arranged at intervals;

[0061] More specifically, the first pleat line 4 is connected to the second pleat line 5; or,

[0062] the first pleat line 4 is separated from the second pleat line 5;

[0063] More specifically, the first pleat line 4 is perpendicular to the second pleat line 5, or,

[0064] an included angle A is formed between the extension line of the first pleat line 4 and the second pleat line 5, and the value range of the included angle A is 0° < A < 90°, or greater than 90° < A < 180°.

[0065] Specifically, the front panel 1 or the rear panel 2 vertically extends downward from the middle of the collar 12 of the clothing body to the hem 10 of the clothing body to form a central reference line;

[0066] Each of the first pleat lines 4 is configured to be orthogonal to the central reference line in the planar projection of the front panel 1 or the rear panel 2;

[0067] Each of the second pleat lines 5 is configured to extend obliquely with respect to the central reference line in the planar projection of the front panel 1 or the rear panel 2;

[0068] The setting of each pleat line and the velvet grid 6 is conducive to accurately dividing the filling area, enabling the hydrophobic thermal insulation material to be evenly distributed within each velvet grid 6, avoiding the accumulation or displacement of the filling material, and ensuring the stability and uniformity of the thermal insulation effect; on the other hand, the velvet grid 6 structure can effectively fix the filling material, and even after multiple wearings and washings, it can further prevent the hydrophobic thermal insulation material from agglomerating, maintaining the good thermal insulation performance and appearance of the water-repellent down T-shirt, and extending the service life of the product.

[0069] Specifically, the rear panel 2 in the second down-filling area 22 includes a second inner layer, a second down-filling layer, and a second outer layer arranged in sequence from the inside to the outside, and the upper back 21 is overlapped and connected into one body through the second inner layer and the second outer layer in sequence; compared with the second down-filling area 22, the upper back 21 has only two layers of fabric, making the upper back 21 more breathable;

[0070] Both the first inner layer and the second inner layer are integrally cut and formed from breathable cotton cloth to further enhance the air permeability of the front panel 1 and the rear panel 2;

[0071] Both the first and second outer layers are woven from polyester fiber yarn, cotton yarn, and spandex yarn. It should be noted that each of the outer layers also contains cotton, which helps to further increase the breathability of the front panel 1 and the back panel 2, thereby reducing the user's stuffiness.

[0072] The single-layer elastic woven structure is woven from highly elastic yarn, including but not limited to spandex core-spun yarn or elastic polyester yarn, to ensure that the side waist seam 7 and the sleeve 8 are elastic.

[0073] Specifically, the side waist seam 7 and the skin-contact side of the sleeve 8 are both provided with fleece, and the skin-contact sides of the first inner layer and the second inner layer are also provided with fleece.

[0074] It should be noted that manufacturers can add fleece according to design requirements to enhance warmth and improve comfort when in contact with the user's skin.

[0075] Specifically, the hydrophobic and warming material is water-repellent down, and in this embodiment, water-repellent goose down is preferred.

[0076] It should be noted that water-repellent goose down is produced by applying a special chemical treatment to the surface of natural goose down, forming a durable hydrophobic film on the surface of the natural goose down. This gives the goose down water-repellent properties, reduces moisture absorption in humid environments, dries quickly, and maintains its fluffiness and warmth, thus effectively overcoming the defect of traditional down whose warmth retention decreases after getting damp.

[0077] The down filling amount of both the first down filling area 11 and the second down filling area 22 is 10g / m². 2 -30 g / m 2 In this embodiment, a filler of 10 g / m³ is preferred. 2 -20 g / m 2 This filling range ensures that the water-repellent down T-shirt has enough hydrophobic insulating material to achieve good warmth retention, while also preventing the T-shirt from becoming too thick and bulky due to excessive down filling, which would affect the comfort and flexibility of wearing it.

[0078] Specifically, the collar 12 of the garment body and the cuff 81 of the sleeve 8 are provided with elastic rib structure, which is woven from cotton and spandex blend yarn.

[0079] The surface of the elastic ribbed structure is provided with a protective coating to achieve the effect of preventing dirt and grime; the protective coating is one of the following: a single-component nanocomposite coating, a super-dirt-repellent nanocoating, a nano-titanium dioxide composite coating, or a modified nanoparticle-reinforced organosilicon coating.

[0080] Specifically, the neckline 12 is set to any one of round neck, square neck, and V-neck, and in this embodiment, a round neck is preferred.

[0081] Specifically, each of the side waist seams 7 forms an arc-shaped waist seam 9 at the junction with the front panel 1 and the back panel 2, and each of the arc-shaped waist seams 9 extends from the side edge of the armhole to the hem 10 of the garment body.

[0082] When worn, when viewed from the front or back of the garment, the curved waist seam 9 presents as a continuous curve that bulges outwards towards the outside of the garment, and this curve configuration visually creates the effect of narrowing the waist area.

[0083] Specifically, the garment body has an antibacterial and deodorizing layer in the underarm area 82 to achieve an antibacterial and deodorizing effect on the underarms; the antibacterial and deodorizing layer is made of natural antibacterial fabric; or,

[0084] The antibacterial and deodorizing layer is a sweat-absorbing strip; or...

[0085] The antibacterial and deodorizing layer includes multiple breathable pores; or,

[0086] The antibacterial and deodorizing layer is a coating containing an antibacterial agent, specifically one of a nano-silver antibacterial coating, a nano-titanium dioxide antibacterial coating, or a quaternary ammonium salt antibacterial coating.

[0087] More specifically, the antibacterial and deodorizing layer is evenly applied to the inner surface of the armpit area 82.

[0088] Specifically, the shoulder 3 adopts a straight shoulder or a dropped shoulder design; wherein, the shoulder line of the straight shoulder design naturally conforms to the human shoulder line, while the shoulder line of the dropped shoulder design is lower than the human shoulder line;

[0089] In this embodiment, the shoulder 3 adopts a straight shoulder design, which better conforms to the natural shape of the human shoulder 3 and effectively improves the fit and comfort of the garment.

[0090] Specifically, the entire fabric surface of the garment body is provided with a three-proof and anti-yellowing structure; the three-proof and anti-yellowing structure is the fabric surface structure after being treated with three-proof technology and anti-yellowing technology;

[0091] More specifically, the three-proof finishing process involves padding, pre-drying, and baking with fluorinated acrylate finishing agents; wherein, the fluorinated finishing agent forms a low surface tension coating on the fiber surface, constructs an oil-repellent layer through the directional arrangement of fluorinated alkyl side chains, and at the same time, the cross-linked monomers form a three-dimensional network structure to enhance wash resistance;

[0092] More specifically, the anti-yellowing process involves treating the fabric with an anti-yellowing agent that does not contain ADH. This anti-yellowing agent introduces a short-chain cyclic strong reducing structure (such as Able-Func AHY) that does not contain active hydrogen, which is preferentially oxidized during heat setting or molding, protecting the amino groups of the fabric from oxidation, thereby preventing yellowing, and without the risk of formaldehyde release.

[0093] It should be noted that after the above two processes, the three-proof and anti-yellowing structure will be formed on the surface of the fabric, so that the treated fabric can simultaneously achieve three-proof (waterproof, oilproof, and stainproof) functions and anti-yellowing performance.

[0094] 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.
