Description

Technical Field

[0001] This application relates to the field of women's underwear, and more specifically, it relates to a breathable foamed jelly-like soft rubber underwear. Background Technology

[0002] As female consumers become more self-aware, their demand for lingerie products is also changing, with a growing demand for different styles and functions, and an increasingly strong need for comfort.

[0003] A woman's breasts are mostly composed of fatty tissue, supported internally by ligaments and skin. However, this support is sometimes insufficient, causing the breasts to shift and rub against each other, resulting in pain and discomfort. The bra, as one of the underwear worn by women, is designed to cover and support the breasts.

[0004] In summer, as temperatures rise, sweat is absorbed by clothing and can easily breed bacteria. To facilitate production, existing fabrics are often treated with antibacterial finishing to obtain antibacterial properties. However, during subsequent washing, the antibacterial finishing process results in poor washability of the fabric, leading to a decrease in its antibacterial properties after washing. Summary of the Invention

[0005] In order to improve the washability of the fabric, reduce the impact of washing on the antibacterial properties of the fabric, and thus reduce the impact on the durability of the antibacterial effect of the fabric, this application provides a breathable foamed jelly soft rubber underwear.

[0006] This application provides a breathable foamed jelly-like soft gel underwear, employing the following technical solution:

[0007] A breathable foamed jelly-like soft rubber bra includes a molded cup portion, with a back band portion fixedly connected to both sides of the molded cup portion. The two back band portions are detachably connected. The molded cup portion is provided with shoulder straps. The molded cup portion includes a center gore, with two symmetrically arranged cups fixedly connected to the center gore. A jelly strip for supporting the breasts is fixedly connected to the center gore. The cups include a first fabric layer and a second fabric layer spaced apart from the inside to the outside. A breathable foamed cup is provided between the first fabric layer and the second fabric layer. The back band portion, the first fabric layer, and the second fabric layer are all made of fiber fabric.

[0008] The fiber fabric is made by blending the following raw materials in parts by weight: 50-70 parts modified nylon fiber, 25-35 parts polyurethane fiber, 6-12 parts heat dissipation fiber, and 5-7 parts modified viscose fiber.

[0009] The modified nylon fiber comprises the following raw materials: polyamide, reactive alkylphenol resin, polyvinyl alcohol and polyhexamethylene biguanide, in a weight ratio of 28:2:12:1.

[0010] By adopting the above technical solutions, fabrics are made from these four types of fibers. For modified nylon fibers, polyamide is used as the main component. Reactive alkylphenol resin and polyvinyl alcohol enhance the bonding strength of polyhexamethylene biguanide on polyamide, making it less likely for polyhexamethylene biguanide, as an antibacterial component, to fall off. At the same time, reactive alkylphenol resin improves the adhesion stability of polyvinyl alcohol on polyamide, thereby further improving the bonding strength of polyhexamethylene biguanide on polyamide, further reducing the impact of washing on the antibacterial properties of the fabric, and thus reducing the impact on the durability of the fabric's antibacterial effect.

[0011] Preferably, the modified nylon fiber is prepared by the following steps: extruding and granulating polyamide, reactive alkylphenol resin, polyvinyl alcohol and polyhexamethylene biguanide, and then melt spinning to obtain the modified fiber.

[0012] By adopting the above technical solution, polyamide, reactive alkylphenol resin, polyvinyl alcohol and polyhexamethylene biguanide are mixed by melt spinning process to obtain the corresponding modified nylon fiber and improve the overall bonding stability.

[0013] Preferably, the modified viscose fiber comprises the following raw materials: graphene, chitosan, and viscose spinning solution, wherein the weight ratio of graphene to chitosan and viscose spinning solution is 5:1:100.

[0014] By adopting the above technical solution, viscose fiber can be obtained by using viscose spinning solution as the main component. Chitosan, through modification, improves the stability of graphene in viscose fiber. Both graphene and chitosan can play an antibacterial role, thus obtaining modified viscose fiber with antibacterial ability.

[0015] Preferably, the modified viscose fiber further includes Artemisia argyi extract, wherein the weight ratio of Artemisia argyi extract to graphene is 1:1.

[0016] By adopting the above technical solution, the addition of Artemisia argyi extract mixed with graphene and chitosan helps to improve the antibacterial ability of modified viscose fiber. Furthermore, using graphene as an adsorption carrier helps to improve the dispersion performance of Artemisia argyi extract in chitosan solution, thereby further enhancing the antibacterial ability of modified viscose fiber.

[0017] Preferably, the modified viscose fiber is prepared by the following steps: chitosan is prepared into a solution, and then a mixture of Artemisia argyi extract and graphene is added, and then mixed with viscose spinning solution to obtain modified viscose fiber.

[0018] By adopting the above technical solution, graphene is used as a carrier for Artemisia argyi extract, which is then mixed into chitosan solution and finally mixed and dispersed evenly with viscose spinning dope to obtain modified viscose fiber. The operation is simple and convenient, and it effectively improves the antibacterial ability of modified viscose fiber.

[0019] Preferably, the heat dissipation fiber includes jade fiber, mica fiber and pearl fiber, and the weight ratio of the jade fiber, mica fiber and pearl fiber is 1:1:1.

[0020] By adopting the above technical solution, jade fiber, mica fiber and pearl fiber are mixed and added to the fabric production, thereby effectively improving the heat dissipation performance of the fabric, so that the final product has a cool feeling when in contact, and improves the comfort when wearing it in summer.

[0021] Preferably, the fiber fabric is prepared by the following steps: S1, modified nylon fiber, polyurethane fiber, jade fiber, pearl fiber, mica fiber and modified viscose fiber are respectively opened and pretreated and combed into slivers; S2, the slivers obtained after opening the six fibers in S1 are combined to make slivers; S3, the slivers are drawn and twisted to make blended yarn, and then the blended yarn is woven to obtain the fiber fabric.

[0022] By adopting the above technical solution, multiple fibers are first opened and pretreated and combed into slivers, then combined to form mature slivers to obtain blended yarn, and finally fiber fabric is obtained, which effectively improves the mixing uniformity and bonding tightness of each fiber component.

[0023] Preferably, the modified nylon fiber, polyurethane fiber, heat-dissipating fiber, and modified viscose fiber are all 25D / 34F microfibers.

[0024] By adopting the above technical solution, the fabric made from ultra-fine soft fibers is then used to make the product, thereby effectively improving the wearing comfort of the product.

[0025] In summary, this application has the following beneficial effects:

[0026] 1. In this application, the modified nylon fiber is first modified with reactive alkylphenol resin to improve the water resistance of polyvinyl alcohol, thereby improving the adhesion and stability between polyvinyl alcohol and polyamide. Polyhexamethylene biguanide acts as an antibacterial agent. Then, the polyvinyl alcohol and reactive alkylphenol resin improve the bonding strength of hexamethylene biguanide on polyamide, thereby improving the wash resistance of the modified nylon fiber and effectively reducing the impact of washing on the antibacterial durability of the fabric.

[0027] 2. In this application, modified nylon fiber modified with antibacterial agent, modified viscose fiber with antibacterial ability and polyurethane fiber are mixed as some raw materials, thereby effectively improving the antibacterial ability of the fabric.

[0028] 3. In this application, jade fiber, mica fiber and pearl fiber are used as heat dissipation fibers to improve the cooling sensation of the fabric and thus improve the wearing comfort of the product.

[0029] 4. Jade fiber not only plays a role in heat dissipation, but its structure also allows sweat to penetrate into the jade fiber in a short time. During this process, both modified nylon fiber and modified viscose fiber can effectively inhibit the activity of bacteria. Then, the sweat is discharged to the outside of the jade fiber and comes into contact with the air under the capillary action of the microporous structure of the jade fiber, reducing the growth of bacteria during the sweat soaking process.

[0114] GB / T 3923.1-2013 Textiles - Tensile Properties of Fabrics - Part 1: Determination of Breaking Strength and Elongation at Break (Strip Method)

[0115] GB / T 20944.3-2008 "Evaluation of antimicrobial properties of textiles - Part 3: Shaking method" tests the antimicrobial rate of fabrics against Staphylococcus aureus, Escherichia coli and Candida albicans, as well as the antimicrobial rate after 50 washes.

[0116] Table 2 Performance Test Data

[0117]

[0118]

[0119] As can be seen from Example 3 and Comparative Examples 1-3, and Table 2, using reactive alkylphenol resin and polyvinyl alcohol as the linking components between polyhexamethylene biguanide and polyamide improves the bonding stability of polyhexamethylene biguanide to polyamide. The reactive alkylphenol resin modifies polyvinyl alcohol, improving the water stability during the bonding of polyvinyl alcohol and polyamide, thus further improving the bonding stability of polyvinyl alcohol to polyamide and polyhexamethylene biguanide. This improves the wash resistance of fabrics prepared with modified nylon fibers and reduces the impact of washing on the antibacterial properties of the fabric.

[0120] Based on Examples 3-6 and Comparative Example 4, and referring to Table 2, it can be seen that viscose fiber can be produced using viscose spinning solution as the main component. Chitosan modification improves the stability of graphene within the viscose fiber. The addition of Artemisia argyi extract, mixed with graphene and chitosan, allows graphene to act as an adsorbent carrier, helping to improve the dispersion performance of Artemisia argyi extract in the chitosan solution. Graphene, chitosan, and Artemisia argyi extract all exhibit antibacterial effects, contributing to enhanced antibacterial capabilities of the modified viscose fiber. Incorporating graphene, chitosan, and Artemisia argyi extract into the viscose fiber during the spinning process improves bonding stability and reduces the impact of washing on the antibacterial properties of the fiber and even the fabric.
