Description

Technical Field

[0001] This utility model relates to the field of underwear mold cup technology, specifically to an underwear mold cup with good breathability. Background Technology

[0002] Traditional bra cups (such as sponge cups and silicone cups) are mostly made of dense materials, which have poor breathability, easily leading to stuffiness, sweat accumulation, and skin discomfort with prolonged wear. Existing improvements (such as perforated designs) can enhance breathability, but they significantly reduce the support of the cup, and the holes are prone to deformation, affecting aesthetics. Therefore, there is an urgent need for a bra cup that combines good breathability with structural stability. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a breathable bra cup, which has the advantages of good breathability and solves the problem of poor breathability of bra cups.

[0004] This invention relates to a breathable bra cup, comprising a main body composed of a skin-friendly breathable layer, a three-dimensional support frame layer, and an outer shaping layer, arranged in the following order from the inside out: the main body consists of the skin-friendly breathable layer, the three-dimensional support frame layer, and the outer shaping layer. The three-dimensional support frame layer has a three-dimensional mesh structure and is filled with phase change temperature-regulating microcapsules. An air convection channel is formed between the three-dimensional support frame layer and the outer shaping layer. The lower edge of the surface of the main body of the bra cup has vents communicating with the air convection channel. This invention achieves a self-driven air circulation system through a three-stage linkage: rapid moisture wicking by the skin-friendly breathable layer → air permeability through the mesh gaps of the three-dimensional support frame layer → active heat dissipation through the air convection channel. Compared with traditional bra cups, the breathability efficiency is improved by more than 40%. At the same time, the phase change temperature-regulating microcapsules absorb / release heat when body temperature fluctuates, reducing the duration of stuffiness by 50%.

[0005] This invention relates to a breathable underwear cup, wherein the skin-friendly breathable layer is a honeycomb mesh textile material with an open area ratio of ≥70%. This high-open-pore structure increases the moisture permeability of the skin contact surface to 0.8 g / (m²). 2 The measured value is above h), and the hexagonal cells of the honeycomb mesh can disperse pressure and avoid indentations caused by traditional plain weave fabrics.

[0006] This invention relates to a breathable bra cup, wherein the hollow area of ​​the three-dimensional support skeleton layer accounts for 60%-80%. While ensuring support strength (compression deformation <8%), the hollow area forms a three-dimensional airflow channel, reducing the overall density of the cup to 0.15 g / cm³. 3 The following (35% lighter than traditional sponge) significantly improves the wearing lightness.

[0007] The present invention provides a breathable bra cup with 8-12 breathable holes of 1-2mm in diameter. The bottom breathable hole serves as a hot air outlet, forming a chimney effect with the air inlet of the top skin-friendly layer. In actual testing, it can still maintain an airflow speed of 0.2m / s under static conditions, thus solving the problem of sweat accumulation under the armpits and in the vest area.

[0008] This invention relates to a breathable underwear cup, wherein the phase change temperature-regulating microcapsules have a particle size of 0.1-0.5mm and are uniformly dispersed within the three-dimensional grid of the three-dimensional support skeleton layer; the cross-section of the air convection channel is a wave-shaped or sawtooth structure; the particle size control of the phase change temperature-regulating microcapsules is: >0.1mm: to avoid leakage through the mesh gaps (retention rate >95%), <0.5mm: to prevent clogging of the mesh and affecting breathability (breathability retention rate ≥85%); the wave / sawtooth channel design: extends the airflow path by about 30%, enhances heat exchange efficiency, and the sawtooth protrusions provide anti-collapse support; after 10,000 compression tests, the channel deformation rate is <5%.

This utility model forms a self-driven air circulation system through a three-stage linkage of rapid moisture wicking by the skin-friendly breathable layer, air permeability through the mesh gaps of the three-dimensional support skeleton layer, and active heat dissipation through the air convection channel. Compared with traditional molded cups, the breathability efficiency is improved by more than 40%. At the same time, the phase change temperature regulating microcapsules absorb / release heat when body temperature fluctuates, reducing the duration of stuffiness by 50%.

The arrangement of these components from the inside out is as follows: the bra cup body 1 consists of the skin-friendly breathable layer 101, the three-dimensional support skeleton layer 102, and the outer shaping layer 103. The three-dimensional support skeleton layer 102 has a three-dimensional mesh structure and is filled with phase-change temperature-regulating microcapsules 1021. The three-dimensional support skeleton layer 102 and the outer shaping layer 103 are connected... An air convection channel 104 is formed between 03. The lower edge of the surface of the bra cup body 1 is provided with a breathable hole 2 that communicates with the air convection channel 104. This utility model forms a self-driven air circulation system through a three-stage linkage of rapid moisture wicking by the skin-friendly breathable layer 101, air permeability through the mesh gaps of the three-dimensional support skeleton layer 102, and active heat dissipation by the air convection channel 104. Compared with traditional molded cups, the breathability efficiency is improved by more than 40%. At the same time, the phase change temperature regulating microcapsule 1021 absorbs / releases heat when the body temperature fluctuates, reducing the duration of stuffiness by 50%.

[0022] The skin-friendly and breathable layer 101 is a honeycomb mesh textile material with an open porosity of ≥70%. This high-open-porosity structure increases the moisture permeability of the skin contact surface to 0.8 g / (m²). 2 The measured value is above h), and the hexagonal cells of the honeycomb mesh can disperse pressure and avoid indentations caused by traditional plain weave fabrics.

[0023] The hollow area of ​​the three-dimensional support skeleton layer 102 accounts for 60%-80%. While ensuring support strength (compressive deformation <8%), the hollow area forms a three-dimensional air channel, reducing the overall density of the mold cup to 0.15g / cm³. 3 The following (35% lighter than traditional sponge) significantly improves the wearing lightness.

The bottom ventilation holes 2 serve as hot air outlets, forming a chimney effect with the air inlet of the top skin-friendly layer. In actual tests, it can still maintain an airflow speed of 0.2m / s in a static environment, solving the problem of sweat accumulation under the armpits and in the vest area.

[0025] The phase change temperature-regulating microcapsules 1021 have a particle size of 0.1-0.5 mm and are uniformly dispersed within the three-dimensional grid of the three-dimensional support skeleton layer 102. The air convection channel 104 has a wavy or sawtooth structure in cross-section. The particle size control of the phase change temperature-regulating microcapsules 1021 is as follows: >0.1 mm: to avoid loss through the grid gaps (retention rate >95%), <0.5 mm: to prevent grid blockage and affect air permeability (air permeability retention rate ≥85%). The wavy / sawtooth channel design extends the airflow path by about 30%, enhances heat exchange efficiency, and the sawtooth protrusions provide anti-collapse support. After 10,000 compression tests, the channel deformation rate is <5%.
