Shapewear Garment

The present application claims priority to Chinese Patent Application No. 202521497344.8, filed on Jul. 15, 2025, the entire contents of which are incorporated herein by reference.

The embodiments of the present application relate to the technical field of maternal and infant products, and particularly to a shapewear garment.

Shapewear, as a common garment for enhancing body curves, is usually made from elastically integrated fabric that uniformly compresses the wearer's chest, abdomen, back, and buttocks. In traditional designs, chest support relies on built-in underwires or the tensile strength of the overall fabric, while the abdomen is only provided with basic pressure through a single layer of elastic material. Although such structures achieve basic shaping, they are limited by the uniform modulus of elasticity of the fabric and non-differentiated tension distribution, making it difficult to achieve refined shaping control for key areas of the body.

There are two key deficiencies in the traditional design: First, the abdominal shaping effect is insufficient. Due to the uniform modulus of elasticity of the fabric, the abdomen cannot receive significantly higher directional pressure than other areas, resulting in low efficiency in fat gathering. If elasticity is increased across the board to enhance shaping, it may lead to chest compression or impaired blood flow in the lower limbs, making it difficult to balance comfort with shaping effectiveness. Second, the bust lifting function fails. While underwire structures can temporarily support the breasts, long-term wear may cause marks and restrict movement. In non-underwire designs, fabric with uniform tension struggles to maintain effective lift along the lower edge of the breasts during movement, resulting in inadequate upward support and accelerating sagging.

Therefore, the core challenge faced by current shapewear technology is the inability to provide strong and lasting targeted compression for the abdomen, a key area, while ensuring overall wearing comfort and freedom of movement. The design of uniform elasticity results in insufficient abdominal pressure, and the approach of simply increasing elasticity across the board or incorporating rigid components introduces new issues, such as excessive pressure on non-target areas or a significant decline in comfort. The field urgently needs an innovative solution that can precisely, effectively, and comfortably enhance the compression effect of shapewear on the abdomen.

Given the deficiencies in the prior art, an embodiment of this application provides a shapewear garment that addresses issues of poor abdominal shaping effect, wearing discomfort, and insufficient bust lifting and shaping in existing shapewear garments.

As shown in, in embodiments of the present application, the shapewear garment may comprise: an upper portion, a middle portion, a lower portion, and an abdominal compression panel.

The upper portionis configured to extend around the wearer's chest and upper back when worn.

The middle portionis connected to the upper portionand positioned below the upper portion. The middle portionincludes an abdominal covering portionand a lower back covering portion. The abdominal covering portionis configured to cover the wearer's abdomen when worn, and the lower back covering portionis configured to cover the wearer's lower back when worn.

The abdominal compression panelis laminated with and combined with the abdominal covering portion. The modulus of elasticity of the abdominal compression panelis greater than that of the upper portion, the middle portion, and the lower portion. Specifically:

The modulus of elasticity of the abdominal compression panelis greater than that of the upper portion; the modulus of elasticity of the abdominal compression panelis greater than that of the middle portion; and the modulus of elasticity of the abdominal compression panelis greater than that of the lower portion.

Through this differentiated modulus of elasticity design, the abdominal compression paneldelivers targeted stronger compression forces to the abdominal region. This effectively sculpts waist and abdominal contours while maintaining comfortable wearability in other areas, achieving an optimal balance between localized precision shaping and overall wearing comfort.

In one embodiment, the modulus of elasticity of the abdominal compression panelmay range from 1.6 to 2.4 GPa, specifically including but not limited to 1.6 GPa, 2 GPa, or 2.4 GPa; while the modulus of elasticity of the upper portion, middle portion, and lower portionmay range from 0.9 to 1.3 GPa, specifically including but not limited to 0.9 GPa, 1 GPa, or 1.3 GPa. These values are provided merely as examples and do not limit the scope of protection of this application.

In one embodiment, the abdominal compression panelemploys nylon-spandex fabric formed by blending nylon yarn and spandex yarn. The upper portion, middle portion, and lower portionmay similarly utilize nylon-spandex fabric blended from nylon yarn and spandex yarn. The knitted yarn composition for the upper portion, middle portion, and lower portionmay comprise 70% to 80% nylon and 20% to 30% spandex, whereas the knitted yarn composition for the abdominal compression panelmay comprise 40% to 50% nylon and 50% to 60% spandex. The modulus of elasticity is adjusted by varying the spandex yarn content percentage in the nylon-spandex fabric. The above data serves only as an example. To ensure the modulus of elasticity of the abdominal compression panelexceeds that of the upper portion, middle portion, and lower portion, it is sufficient to maintain a higher spandex yarn content percentage in the abdominal compression panelcompared to those portions.

In a specific embodiment, the knitted yarn composition of the upper portion, middle portion, and lower portioncomprises 74.5% nylon and 25.5% spandex, while the abdominal compression panelcomprises 45% nylon and 55% spandex. The use of nylon-spandex fabric herein is solely exemplary for illustrating how to achieve a higher modulus of elasticity in the abdominal compression panelrelative to the upper portion, middle portion, and lower portion. Those skilled in the art will readily appreciate that the upper portion, middle portion, lower portion, and abdominal compression panelmay alternatively employ other materials such as polyester-spandex fabric.

In one embodiment, the abdominal compression panelis disposed on the interior side of the abdominal covering portion, wherein the interior side is closer to the wearer's skin when worn. Positioning the abdominal compression panelon the interior side enables seamless appearance of the shapewear garment for enhanced aesthetics. This interior configuration allows direct skin contact, ensuring efficient pressure transmission while reducing fabric slippage, thereby improving both abdominal shaping efficacy and wearing stability/comfort. It should be understood that in alternative embodiments, the abdominal compression panelmay be disposed on the exterior side of the abdominal covering portion, which faces away from the wearer's skin during wear.

In one embodiment, the abdominal compression panelis combined with the abdominal covering portionvia adhesion. In other embodiments, the abdominal compression paneland abdominal covering portionmay be combined through sewing, without limitation in the embodiments of this application. Adhesives for bonding may include, but are not limited to: hot melt pressure-sensitive adhesive, water-based eco-friendly adhesive, reactive polyurethane hot melt adhesive, acrylic adhesive, or polyurethane adhesive.

In one embodiment, the coefficient of friction of the interior surface of the abdominal compression panelis less than that of the interior surface of the abdominal covering portion. In one implementation, the interior surface of the abdominal compression panelundergoes specialized surface treatment to achieve a significantly lower coefficient of friction than the abdominal covering portion, thereby reducing skin friction discomfort during wear.

In one embodiment, the interior surface of the abdominal compression panelundergoes specialized low-friction treatment, resulting in a coefficient of friction significantly lower than that of the abdominal covering portion. Specifically: the static coefficient of friction of the interior surface of the abdominal compression panelis controlled within the range of 0.15-0.25, and the kinetic coefficient of friction is 0.12-0.20; whereas the static coefficient of friction of the interior surface of the abdominal covering portionis 0.30-0.45, and the kinetic coefficient of friction is 0.25-0.40. This differential friction characteristic design reduces friction resistance between the abdominal compression paneland the skin by approximately 40% compared to the covering portion, effectively enhancing wearing comfort. Test data indicates that even after 50 standard washing cycles, the low-friction performance of the abdominal compression panelretains over 85% effectiveness. This technical solution is implemented through silicone finishing agents and nano-coating processes, being particularly suitable for shapewear garments requiring extended wear or high-intensity exercise.

In one embodiment, the low-friction characteristics of the abdominal compression panelare achieved through specialized treatment processes, primarily including the following aspects. For example: First, in material selection, the abdominal compression paneluses silicone-finished nylon/spandex blended fabric with approximately 80% nylon and 20% spandex. This blend ratio ensures elasticity while providing an ideal substrate for subsequent surface treatment. In contrast, the covering portion uses conventional 75% nylon and 25% spandex blended fabric without specialized low-friction treatment. Second, a dual-modification technique is adopted for surface treatment: plasma treatment first activates and cleans the fabric surface to enhance adhesion of subsequent treatment agents; then a padding process applies silicone finishing agent, cured at 150° C. for 30 seconds to form a uniform film. To further enhance the effect, an optional polyurethane-siloxane composite nano-coating with a thickness of 0.5-1.0 μm may be applied. This combined treatment process forms a smooth and durable low-friction surface on the interior side of the abdominal compression panelwhile maintaining good breathability and elasticity. Tests confirm that the treated fabric not only exhibits significantly reduced initial friction coefficients but also maintains stable low-friction performance after multiple washes and abrasion cycles, fully meeting long-term wear requirements for shapewear.

In one embodiment, at least portions of the shapewear garment incorporate xylitol yarn. In one embodiment, at least portions (for example, upper portion, middle portion, lower portion, abdominal compression panel) of the shapewear garment are made with xylitol yarn, and its production process may include the following: encapsulating xylitol powder in heat-resistant microcapsules to prevent decomposition during spinning; mixing and melting xylitol microcapsules with base materials such as nylon to form spinnable masterbatch pellets; employing skin-core structure spinning where the outer layer contains xylitol masterbatch (providing cooling function) and the core layer consists of elastic fibers (e.g., spandex) to ensure the garment's elasticity; knitting xylitol yarn into fabric and preserving xylitol activity through a low-temperature setting process.

As shown in, a bust support areais disposed on the outer surface of the upper portion. The bust support areais configured to be positioned below the wearer's chest when worn and located above the abdominal compression panelwhen worn. The textile tension of the bust support areais greater than that of adjacent areas around the bust support area.

In one embodiment, the bust support areaextends horizontally in an elongated strip configuration and may extend continuously onto the upper back covering portion. A support regionis formed on the outer surface of the upper back covering portion, with the bust support areaand the support regionintegrally connected to form an annular constriction structure resembling an underbust band, thereby enhancing the shaping effect of the lower bustline.
