Abstract
Description
Technical Field
[0001] This utility model belongs to the field of underwear technology, specifically relating to a three-dimensional shaping underwear. Background Technology
[0002] Underwear, as a daily necessity, generally refers to close-fitting lower body underwear, and is divided into men's and women's styles.
[0003] However, existing underwear has the following problems:
[0004] 1. Unreasonable pressure distribution: Traditional underwear designs do not differentiate pressure designs based on the fat distribution and physiological characteristics of the buttocks, abdomen, and groin, resulting in limited shaping effects (such as insufficient correction of sagging buttocks) or excessive local pressure (such as strong abdominal pressure).
[0005] 2. Limited material and fabric structure: Most underwear products use homogeneous elastic fabric, which lacks precise control over the elastic recovery rate of different areas. For example, the upper thighs are not tightened enough and the buttocks are not lifted effectively.
[0006] 3. Conflict between comfort and functionality: Existing technology makes it difficult to balance shaping pressure and breathability. Excessive pressure in the abdominal area may affect blood circulation, while insufficient support in the buttocks can easily lead to a loose shape.
[0007] 4. Severe homogenization of styles: Traditional triangle panties have a single shaping structure, which cannot meet the personalized needs of women with different body types, and lack targeted protection design (such as the uterine area). Summary of the Invention
[0008] In view of this, the purpose of this utility model is to provide a three-dimensional shaping underwear to solve the problem that existing underwear has a poor shaping effect on the buttocks and abdomen.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A three-dimensional shaping underwear, comprising a pant body, wherein the pant body is provided with an abdominal shaping area and a buttock shaping area;
[0011] The fabric in the abdominal shaping area is woven from warp and weft yarns to form a chest-lifting structure or a faux rib structure.
[0012] The hip shaping area includes hip support area one or hip support area two. Hip support area one has a smoothly transitioning X-shaped structure to mainly support the hips from the inside. Hip support area two has a smoothly transitioning W-shaped structure to mainly support the hips from below. Hip support area one is woven from warp and weft yarns to form a plain weave structure or a mesh structure. The fabric of hip support area two is woven from warp and weft yarns to form a chest-lifting structure or a faux rib structure.
[0013] In a possible implementation, the second hip support area includes a left hip support area and a right hip support area, both of which are semi-circular.
[0014] In one possible implementation, the abdominal shaping area includes a main shaping area corresponding to the human abdominal region, which is a semi-circle or an inverted triangle.
[0015] In one possible implementation, the abdominal shaping area also includes an edge extension area that extends laterally from the side edge of the main shaping area to the back waist of the pants.
[0016] Among possible implementations, a shaping zone at the root of the thigh is also included, which is a weft-knitted structure formed by alternating weaves of 6 warp yarns and 12 weft yarns.
[0017] In one possible implementation, the shaping area at the root of the thigh has a semi-circular structure.
[0018] In a possible implementation, both the warp and weft yarns are blended yarns, and the blended yarns contain at least one yarn made of spandex.
[0019] In one possible implementation, the pants are briefs or boxer shorts.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This utility model of three-dimensional shaping underwear features corresponding abdominal and hip shaping zones. Based on fat distribution and pressure conditions, different textile structures are used for support and shaping, resulting in more precise shaping. The chest-lifting or faux rib structure provides both good elastic shaping and breathability, while the plain or mesh structure has a slightly lower elastic recovery rate, ensuring a loose and comfortable fit. This design also solves the problems of insufficient elasticity or uneven elasticity distribution of single materials. Attached Figure Description

Detailed Implementation
[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.
[0032] Please refer to Figure 1-8 As shown, an embodiment of this application provides a three-dimensional shaping underwear, including a pant body 1, wherein the pant body 1 is provided with an abdominal shaping area 2 and a buttock shaping area 4.
[0033] The fabric of the abdominal shaping zone 2 is woven from warp and weft yarns to form a chest-lifting structure or a pseudo-rib knit structure. The abdominal shaping zone 2 is used to shape the wearer's abdominal area. After wearing, this zone covers the corresponding abdominal area, and its structure is either a chest-lifting structure or a pseudo-rib knit structure. Chest-lifting structures and pseudo-rib knit structures are denser fabrics used in clothing textiles, resembling a three-dimensional support net for better support. They have moderate elastic recovery, balancing shaping and breathability, and protecting abdominal organs.
[0034] The buttock shaping area 4 may include a first buttock support area 41 or a second buttock support area 42. The first buttock support area 41 has a smoothly transitioning X-shaped structure to mainly support the buttocks from the inside. The second buttock support area 42 has a smoothly transitioning W-shaped structure to mainly support the buttocks from below. The first buttock support area 41 is woven from warp and weft yarns to form a plain weave structure or a mesh structure. The fabric of the second buttock support area 42 is woven from warp and weft yarns to form a chest-lifting structure or a faux rib structure.
[0035] The buttock shaping area 4 can be configured with either buttock support area 1 41 or buttock support area 2 42 as needed. Buttock support area 1 41 corresponds to the groin area of the human buttocks and is used to support the buttocks from the inside out after wearing. Its shape is similar to an X shape and the support parts on both sides are smoothly transitioned arcs. This structure also has a certain support effect on the bottom of the buttocks, so that it can better fit, support and shape. Buttock support area 2 42 is used to support the left and right buttocks of the human buttocks. It supports the left and right buttocks from bottom to top. Its structure is W-shaped and the parts on the left and right sides that support the buttocks are arc-shaped to better fit the buttocks and play a role in support and shaping. The middle part can also play a certain shaping and support role for the left and right buttocks from the inside. Since the first hip support area (41) primarily supports and shapes the hips from the inside out, it experiences relatively less pressure. Therefore, it employs a plain weave or mesh weave structure formed by warp and weft yarns. These two structures have a slightly lower elastic recovery rate, ensuring a loose and comfortable fit and maintaining the natural fullness of the hips. The second hip support area (42) primarily supports the left and right hips from below, experiencing greater pressure. Therefore, it uses a chest-lifting structure or a faux rib weave structure formed by warp and weft yarns. These two structures have a relatively moderate elastic recovery rate, balancing shaping and breathability, and providing better support. It's understandable that a plain weave is the most basic fabric structure, with warp and weft yarns interlacing alternately. Its elastic recovery rate is lower, but it's looser, making the fabric area more comfortable to wear. A mesh weave structure is a fabric structure that creates a perforated structure through weaving, commonly found in warp or weft knitting. It utilizes the interlacing or pulling of yarns to create breathable holes, providing excellent breathability and combining decorative and functional properties.
[0036] Through the above technical solution, corresponding abdominal shaping zone 2 and hip shaping zone 4 are set in the abdomen and buttocks. Based on the fat distribution and pressure, different textile structures are used for support and shaping, making the shaping more precise. Furthermore, the chest-lifting structure or pseudo-ribbed structure can have both good elastic shaping and breathability. The elastic recovery rate of the plain weave structure or mesh structure is slightly lower, which can ensure looseness and comfort. At the same time, it also solves the problem of insufficient elasticity or uneven elasticity distribution of a single material.
[0037] In one embodiment, the second hip support area 42 includes a left hip support area 421 and a right hip support area 422, both of which are semi-circular.
[0038] In this way, the second hip support area 42, divided into a left hip support area 421 and a right hip support area 422, can support the left and right hips respectively. Its semi-circular shape allows for a better fit and shaping, resulting in a more effective shaping effect. Specifically, the second hip support area 42 also includes a top support area 423, which is triangular and provides shaping and support.
[0039] In the specific implementation process, the buttock support area 1 41 and the buttock support area 2 42 can be configured to form different styles of underwear. Of course, they can also be configured together. When configured together, they can be connected to form a structure that can support from the side and the bottom at the same time, thus enabling better shaping.
[0040] In a preferred embodiment of the abdominal shaping area 2, the abdominal shaping area 2 includes a main shaping area 21 corresponding to the abdominal region of the human body, and the main shaping area 21 is semi-circular or inverted triangular.
[0041] By configuring the main shaping area 21 as a semi-circle or inverted triangle, the abdomen can be protected while shaping, ensuring abdominal comfort. Furthermore, the structure, which is wider at the top and narrower at the bottom, combined with the waistband or elastic band of the pants 1, can provide a better lifting effect, which is more conducive to shaping.
[0042] Building upon this, to further enhance the stability of the main shaping area 21, the abdominal shaping area 2 also includes an edge extension area 22. This edge extension area 22 extends laterally from the side edge of the main shaping area to the back waist of the pants 1. The edge extension area 22 is integrally woven with the main shaping area 21, and its lateral extension to the back waist of the pants 1 allows it to provide a more stable shaping effect by relying on the waistline and elastic band after wearing.
[0043] To simultaneously shape the groin area, a groin shaping zone 3 is included. This groin shaping zone 3 is a weft-knitted structure formed by alternating 6 warp yarns and 12 weft yarns. Since there is a significant amount of fat distributed in the groin area, by setting up the groin shaping zone 3 and configuring a textile structure with a higher elastic recovery rate of 6×12 interlaced weave, its longitudinal elongation is low, which can elastically tighten the fat, thereby achieving lifting and shaping of the groin area.
[0044] Specifically, the thigh root shaping area 3 has a semi-circular structure. The semi-circular thigh root shaping area 3 has a larger contact area, thus enabling better lifting and shaping.
[0045] In the embodiments of this application, both the warp and weft yarns are blended yarns, and the blended yarns contain at least one yarn made of spandex material.
[0046] By combining blended yarns with existing blending processes, the smoothness of the fabric surface can be improved, and the addition of spandex can help improve elasticity and resilience. Preferably, the spandex content is greater than or equal to 15% to ensure high elasticity and resilience.
[0047] In practice, the pants 1 are either briefs or boxer shorts.
[0048] Preferred embodiment:
[0049] This embodiment provides a three-dimensional shaping underwear, the technical solution of which is as follows:
[0050] 1. Zonal pressure design
[0051] (1) High pressure area (root of thigh): The 6×12 interlaced tissue is used, which has the highest elastic recovery rate (≥97%), low longitudinal stretching rate, and strong fat tightening effect, which can play a lifting role.
[0052] 2. Material and process optimization
[0053] (1) Yarn selection: Spandex is used as the core raw material with a content of ≥15% to ensure high elasticity and resilience. At the same time, the surface smoothness and heat resistance of the fabric are improved through blending process.
[0054] (2) Combination of tissue structure: Different tissues are seamlessly spliced together by weft knitting technology. For example, the “X” shaped breast lifting tissue on the outer part of the buttocks is combined with the 6×12 interlaced tissues at the root of the thigh to achieve regional functional enhancement.
[0055] 3. Style Design
[0056] (1) Style 1: The breast-lifting tissue or 3+1 faux ribbed tissue is wrapped in a semi-circular shape around the abdomen, protecting it while shaping and ensuring abdominal comfort; the breast-lifting tissue or 3+1 faux ribbed tissue is in an "X" shape supporting the buttocks to maintain fullness; the 6×12 interlaced tissue is in a semi-circular shape to lift the fat at the root of the thighs, improving the tightening effect; plain weave or mesh tissue is distributed in other areas of the boxer briefs to ensure looseness and comfort. Among them, the 3+1 faux ribbed tissue
[0057] (2) Style 2: The breast-lifting tissue or 3+1 false rib tissue wraps around the abdomen in a triangular shape, protecting the abdomen while shaping it and ensuring abdominal comfort; the breast-lifting tissue or 3+1 false rib tissue supports the buttocks in a semi-circular shape, keeping the buttocks full; the 6×12 interlaced tissue lifts the fat at the root of the thighs in a semi-circular shape, improving the tightening effect; the plain tissue or mesh tissue is distributed in other areas of the boxer briefs to ensure looseness and comfort.
[0058] Technical effects:
[0059] 1. Regional elastic grading design: Based on fat distribution and pressure threshold, the boxer briefs are divided into heavy, medium and light pressure zones, and matched with differentiated tissue structures (such as 6×12 interlaced tissue for the groin area) to achieve precise shaping.
[0060] 2. Spandex and multi-structure composite process: By combining high spandex content (≥15%) with breast-lifting structure, 3+1 pseudo-rib structure, and interlaced 6×12 structure, the problem of insufficient elasticity or uneven pressure distribution of traditional single materials is solved.
[0061] 3. Functional seamless splicing technology: Weft knitting process is used to achieve seamless transition between different tissues, avoid seam friction, and improve local shaping strength (such as the "X" shaped support structure of the buttocks).
[0062] 4. Abdominal protection and shaping balance: The semi-circular / triangular wrapping design of the breast-lifting tissue in the medium pressure zone tightens the abdomen while reducing the pressure value (≤4210Pa) to avoid compressing the uterine area.
[0063] Furthermore, it should be noted that the organizational structure described in this application is an existing textile organizational structure. This application mainly achieves a three-dimensional shaping effect by configuring a suitable organizational structure based on different zones and pressure distributions, and simultaneously designing the area shape to improve the shaping effect. Moreover, different textile organizational structures have different elastic recovery properties, i.e., shaping properties. For example, pseudo-rib knit has good shrinkage properties, while mesh knit and interwoven knit (such as plain knit) have poor shaping effects. This is because plain knit and mesh knit have the largest horizontal and vertical dimensions compared to other knits, thus their shaping properties are poor, and they have less binding feeling on the body, which can meet the wearer's comfort requirements to a greater extent. Compared to other knits, interwoven 6×12 knit has the highest elastic recovery rate and the smallest horizontal and vertical dimensions, so this knit has the best shaping properties. Therefore, when used in underwear shaping design, it can reduce size and improve the tightening effect. The elastic recovery rate of chest-lifting and 3+1 pseudo-rib knit is relatively high, second only to interwoven 6×12 knit, but its horizontal and vertical dimensions are larger, so it can meet the requirements of loose comfort and also achieve a shaping effect. For the characteristics or structural design of the above-mentioned organization, please refer to the literature "Design Model of Weft-Knitted Seamless Shapewear Based on Structural Parameters".
[0064] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
