Technical Field
[0001] The utility model belongs to the field of sports underwear, in particular to a sweat-proof and sweat-conducting sports bra. Background Art
[0002] As people pay more attention to health, various fitness activities have been gradually increasing, especially women's demand and energy for fitness, which has driven the demand for sports bras. The main function of sports bras is to prevent women's breasts from being hurt during sports and fitness.
[0003] Most existing sports bras only focus on one function, such as antibacterial, breathable, skin-friendly and comfortable, or a small number of them are composite products with multiple functions. However, there are few reports on solutions that can solve the problem of women sweating during fitness and combine them with quick sweat conduction.
[0004] At present, sports bras are usually designed as double-layer structures due to the need for chest protection. For comfortable sports bras, the outer layer is usually relatively conventional, and the research focus is on the inner layer, which is mainly functional, such as moisture absorption and perspiration, antibacterial and antibacterial, skin-friendly and breathable. If the existing products focus on antibacterial and antibacterial properties, they often change the composition and organization of the fabric of the close-fitting layer to increase the antibacterial and antibacterial functions; if the focus is on improving breathability, they will choose to open several vents on the bra body, or use more breathable and comfortable fabrics as the inner layer, for example: the inner layer fabric uses coffee charcoal / spandex core-spun yarn, bamboo fiber and mulberry silk and other natural or functional yarns with moisture absorption, perspiration and antibacterial properties. However, although the above fabrics have good hygroscopicity, they have poor quick-drying properties and will stick to the skin surface for a long time, making the human body feel sticky; while the functional chemical fiber fabrics with quick-drying properties have relatively poor hygroscopicity, and sweat cannot be discharged in time, resulting in a stuffy feeling.
[0005] During exercise, the human body will sweat a lot, and the sweat will inevitably penetrate into the outer layer. Especially for the female fitness group who pays special attention to their appearance, uneven sweat marks will be left on the bra, which will not only make it uncomfortable to wear, but also affect the appearance and make people embarrassed. In addition, the bra's heart position and lower band will easily accumulate sweat and be difficult to drain, and it will be easy to slide. Sports bra products that can solve the above problems at the same time are basically blank. Utility Model Content
[0006] Aiming at the problem that the sports bra in the prior art lacks the functions of preventing sweat marks and quickly conducting sweat, the utility model provides an anti-sweat mark and sweat-conducting sports bra.
[0007] The technical scheme of the utility model is as follows: a sweat-proof and sweat-conducting sports bra, comprising a front chest piece, a back piece, a heart-shaped piece and a hem, wherein the front chest piece and the back piece constitute a main structure of the sports bra; the heart-shaped piece is arranged at a heart position of the front chest piece, and the hem is arranged below the front chest piece and the back piece; the heart-shaped piece is arranged in contact with the inner layer of the front chest piece, has moisture absorption and expansion performance, and the heart-shaped piece is also provided with concave-convex vertical strips; the hem is provided with concave-convex vertical strips, and when the user sweats, the heart-shaped piece absorbs liquid and expands, and the concave-convex vertical strips on the heart-shaped piece are in contact with the skin, and cooperate with the concave-convex vertical strips on the hem to quickly guide the sweat downwards.
[0008] Furthermore, the front chest piece has a three-layer structure at the chest protection position, the outermost layer is a matte layer, the middle layer is a mold cup, and the layer that fits the skin is a moisture-conducting layer. The matte layer is used to prevent sweat marks; the mold cup is used for chest support and ventilation, and the moisture-conducting layer is a unidirectional moisture-conducting layer, which is used to guide the sweat of the skin to the outside and prevent reverse osmosis.
[0009] Furthermore, the matte layer is a double-sided fabric structure, the surface layer of the double-sided fabric structure is woven from one or two of water-repellent yarns and super matte core-skin structure yarns, and the inner layer of the double-sided fabric structure is woven from hydrophilic yarns.
[0010] Furthermore, the water-repellent yarn is a polyester or nylon yarn treated with a fluorine-free water-repellent agent or obtained by a plasma etching method, and the super-dull sheath-core structure yarn is a sheath-core structure polyester or nylon yarn with a titanium dioxide dulling agent added.
[0011] Furthermore, the mold cup is made of one or more of sponge, latex sponge, vertical sponge or foamed silicone, and the mold cup is provided with a plurality of through holes or meshes for ventilation.
[0012] Preferably, the mold cup also includes antibacterial cloth, and the antibacterial cloth is arranged on the matte layer to have antibacterial and odor-removing functions.
[0013] Furthermore, the moisture-conducting layer is a single-sided fabric or double-sided fabric with unidirectional moisture-conducting functionality; the inner layer of the double-sided fabric is a hydrophilic layer with hydrophilicity; the outer layer of the double-sided fabric is a hydrophobic layer; the hydrophilic layer and the hydrophobic layer are connected through fabric points.
[0014] Furthermore, the front chest piece includes a two-layer structure of a matte layer and a moisture-conducting layer except for the chest protection position; the back piece includes a two-layer structure of a moisture-conducting layer and a matte layer from the inside to the outside.
[0015] Furthermore, the heart-shaped cut piece is a printing adhesive with hygroscopic and expandable properties, and the printing adhesive includes any one or more of polyacrylamide, sodium polyacrylate type expansion polymer, and water-based polyurethane modified acrylic resin.
[0016] Furthermore, the concave part of the concave-convex vertical stripes on the hem is made of polyester yarn for sweat conduction, and the convex part is made of spandex yarn for anti-slip.
[0017] The advantages of the utility model are: when female fitness enthusiasts sweat a lot during exercise, the moisture-conducting layer of the sports bra can quickly absorb sweat and guide it to the surface of the fabric, so that the skin will not endure the sticky feeling of sweat for a long time and feel uncomfortable; and the external matte layer has functions such as anti-sweat, anti-permeable cup, and anti-ultraviolet, so sweat marks will not be revealed, avoiding embarrassment for women. The heart-shaped cut piece can intelligently absorb moisture and expand according to the ambient humidity, so that the concave and convex vertical stripes on the heart-shaped cut piece fit the skin at the heart to guide sweat. Combined with the hem of the bra, the warp knitted fabric with concave and convex vertical stripes and anti-slip sweat-conducting function can guide a large amount of sweat accumulated in the heart and hem more and faster, and prevent the problem of stuffy sweat at the heart and easy slippage of the hem caused by excessive sweat.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] like Figure 1 , 2 As shown, the sweat-proof and sweat-conducting sports bra of the utility model comprises a front chest piece 1, a back piece 2, a heart-shaped piece 3, and a hem 4. The front chest piece 1 and the back piece 2 constitute the main structure of the sports bra; the hem 3 is arranged around the bottom of the sports bra, and the heart-shaped piece 3 is arranged at the heart position and connected to the hem 4.
[0026] Specifically, Figure 2 , 4As shown, the front chest piece 1 is provided without a steel ring, and three layers are provided at the chest protection position of the front chest piece 1, the outermost layer is a matte layer 11, the middle layer is a mold cup 12, and the inner layer (the layer that fits the skin) is a moisture conductive layer 13. The matte layer 11 is a one-piece setting, which has the functions of anti-sweat, anti-penetration, and anti-ultraviolet, so that sweat marks are not easy to show; the mold cup 12 is used for chest support and ventilation, and the moisture conductive layer 13 is a unidirectional moisture conductive layer, which is used to guide the sweat of the skin from the inner layer of the fabric (close-fitting layer) to the outer layer of the fabric (non-close-fitting layer, diffusion layer), and evaporate and diffuse in the outer layer, and at the same time, the moisture or sweat of the outer layer is difficult to penetrate back to the inner layer.
[0027] The matt layer 11 is preferably made of anti-sweat yarn, while ensuring breathability to avoid the feeling of stuffiness caused by the inability of sweat to penetrate. The matt layer 11 is preferably a double-sided fabric, the surface layer of the double-sided fabric is woven from one or two of water-repellent yarn and super-matt skin-core structure yarn, and the inner layer of the double-sided fabric is woven from hydrophilic yarn. The water-repellent yarn is a polyester or nylon yarn obtained by treatment with a fluorine-free water-repellent agent or plasma etching, and the super-matt skin-core structure yarn is a skin-core structure polyester or nylon yarn with titanium dioxide matting agent added; the content of titanium dioxide matting agent accounts for 2.5% to 15% of the fiber ratio. The double-sided fabric is any one of a plain weft fabric, a threaded weave, a twill weave, and a jacquard weave.
[0028] The mold cup 12 is made of one or more of sponge, latex sponge, vertical cotton or foamed silica gel, so that the mold cup has excellent air permeability as a whole; the mold cup 12 may be provided with a plurality of through holes or mesh holes for air permeability. The mold cup 12 may also include a surface antibacterial cloth, which is bonded to the matt layer 11; the antibacterial cloth is woven with one of copper fibers, rare earth fibers, graphene fibers or chemical fibers with plant-based elements, and has the function of antibacterial and deodorizing.
[0029] The moisture conducting layer 13 is made of a unidirectional moisture conducting functional single-sided fabric or double-sided fabric. The unidirectional moisture conducting functional double-sided fabric is realized by the principle of single-parent and single-proof. The inner layer of the double-sided fabric is hydrophilically finished by a hydrophilic printing auxiliary agent or the inner layer is formed of a hydrophilic yarn to form a hydrophilic layer, and the outer layer of the double-sided fabric is formed of a hydrophobic yarn to form a hydrophobicity; the outer layer and the inner layer are connected by a tissue point; the hydrophilic yarn is made of cellulose fiber or a blended yarn of cellulose fiber and nylon polyester, and the cellulose fiber is selected from one or more of cotton, viscose, modal, tencel and bamboo fiber.
[0030] The unidirectional moisture-conducting functional single-sided fabric is woven with yarns made of one of polyester and nylon fibers; the single-sided fabric is then post-finished with a single-parent and single-proof additive or the yarn thickness, jacquard terry or mesh texture are changed to achieve the unidirectional moisture-conducting function.
[0031] The front chest piece 1 has only two layers of structure, namely, a matte layer 11 and a moisture conducting layer 12, except for the middle mold cup 12 provided at the chest protection position. Figure 5 As shown, the back sheet includes two layers of structure, namely, a moisture conducting layer 13 and a matte layer 11 from the inside to the outside.
[0032] like Figure 3 , 6 As shown, the heart-shaped piece 3 is arranged at the heart position of the front chest piece 1, and is arranged to fit the inner layer of the front chest piece 1. The heart-shaped piece 3 can be a printed adhesive with hygroscopic and swelling properties, such as: polyacrylamide, sodium polyacrylate type swelling polymer, water-based polyurethane modified acrylic resin, etc., and concave and convex vertical stripes 31 are arranged on the heart-shaped piece; the printed adhesive expands toward the inner side of the sports bra when the humidity is high or after absorbing water, so that the concave and convex vertical stripes 31 fit the skin.
[0033] The chicken heart position of the sports bra often has a certain gap between it and the skin due to female bone factors and position factors. When the human body sweats during exercise, a large amount of sweat is easily accumulated at the chicken heart position. Usually, sports bras will pay more attention to the breathability at the chicken heart position. However, due to the existence of the gap at the chicken heart position, when a large amount of sweat accumulates, it is difficult to improve the athlete's sticky body feeling only by the breathability of the bra chicken heart position fabric. Therefore, the chicken heart piece 3 provided in the utility model absorbs liquid and swells when encountering sweat to reduce part of the sweat and make the chicken heart piece 3 fit the skin, so that a part of the sweat is discharged downward as soon as possible along the concave and convex vertical strips 31, and the other part is discharged outward through the moisture-conducting layer 13 and the matte layer 11 of the front chest piece; after the athlete stops exercising and the internal environment of the sports bra is dry, the chicken heart piece 3 dries and shrinks back to its original state to ensure wearing comfort.
[0034] The hem 4 is also provided with a circle of concave and convex vertical stripes. The hem is made of warp-knitted sweat-guiding and anti-skid cloth, and is woven by a Raschel warp knitting machine with four comb sections. The first and second comb sections are used as ground combs, and polyester low-elastic yarns are used to weave a double warp structure. The third and fourth comb sections are used as weft linings, and thicker spandex yarns are used to weave a padding structure. The raised parts are spandex yarns, which can achieve an anti-slip effect; the concave parts are polyester yarns, which can achieve the function of guiding sweat and not sticking to the body; the specifications of the polyester low-elastic yarn are 50D and 75D, and the specifications of the spandex yarn are 210D and 280D.
[0035] When the athlete sweats a lot, the heart-shaped piece 1 absorbs water and expands, so that the concave and convex vertical stripes 31 on the heart-shaped piece fit the skin and cooperate with the concave and convex vertical stripes on the hem 4 to quickly guide the sweat downward without accumulating inside the sports bra.
[0036] Example 1
[0037] The matt layer 11 of the front chest piece 1 and the back piece 2 is made of a double-sided fabric with a plain weft stitch, the surface yarn of the double-sided fabric is a water-repellent yarn, and the inner yarn is a water-absorbing yarn, so that the double-sided fabric has the functions of anti-sweat, anti-penetration and anti-ultraviolet.
[0038] The water-repellent yarn is a plasma-etched polyester yarn with a specification of 50D; the water-absorbent yarn is a cotton / nylon staple blended yarn with a yarn specification of 40S. The waterproof yarn and the moisture-absorbent and breathable yarn are woven into a grey fabric using a double-sided weft knitting circular machine, and the matte layer fabric is obtained through pre-treatment, dyeing and finishing, softening finishing, and post-finishing.
[0039] The moisture-conducting layer 13 of the front chest piece 1 and the back piece 2 adopts a double-sided fabric with a weft plain needle structure having a unidirectional moisture-conducting function, and is woven by water-repellent polyester and hydrophilic modified polyester through a double-sided machine. The specification of the water-repellent polyester is 50D, and the specification of the hydrophilic modified polyester is 75D. The water-repellent polyester forms a hydrophobic surface in direct contact with the skin, and the hydrophilic modified polyester forms a hydrophilic surface away from the skin, thereby realizing the unidirectional moisture-conducting function; the water-repellent polyester accounts for 45% of the mass fraction of the moisture-conducting layer fabric, and the mass fraction of the hydrophilic modified polyester accounts for 55% of the total mass.
[0040] The mold cup 12 is latex cotton with antibacterial and deodorizing properties, and a plurality of through holes are provided on the latex cotton to ensure the air permeability of the mold cup.
[0041] The heart-shaped cut piece 3 is a printed adhesive material arranged on the surface of the moisture-conducting layer 13 at the heart position of the front chest piece 1, and is made of a blended resin material of water-based polyurethane modified acrylic acid and water-based polyacrylic acid resin. The heart-shaped cut piece surface is provided with concave-convex vertical stripes 31.
[0042] The hem 4 is woven by a Raschel warp knitting machine with four comb sections. The first and second comb sections are used as ground combs, and polyester low-elastic yarn is used to weave a double warp structure. The third and fourth comb sections are used as weft lining, and thicker spandex yarn is used to weave a cushioning structure. When the back of the weft lining yarn moves laterally in the same direction as the back of the ground comb yarn, the interlacing points of the weft lining yarn are fewer, so that the weft lining yarn is exposed above the extension line of the ground comb. Combined with the yarn arrangement method, a vertical strip-shaped sweat-conducting and anti-slip structure with a concave and convex surface is formed on the bottom layer of the fabric.
[0043] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
