Description

Technical Field

[0001] This invention relates to the field of knitted bra technology, specifically to a functional knitted bra that employs a double-layer integrated knitting process, with a skin-friendly and comfortable inner layer, a far-infrared health-promoting outer layer, and requires no secondary lamination. Background Technology

[0002] As an essential everyday garment for women, comfort, support, and functionality are the core research and development directions for bras. Most bras on the market currently use single-layer fabric or multi-layer glued hot-press composite processes. These products are prone to problems such as fabric delamination, poor breathability, unsatisfactory wearing comfort, and limited functionality. Furthermore, conventional textile fabrics cannot simultaneously provide both a skin-friendly, non-irritating feel and far-infrared health benefits. While hemp fibers possess excellent moisture absorption and antibacterial properties, most hemp fibers are too stiff and irritating to the skin, making them unsuitable for direct use as a close-fitting layer. Currently, the market urgently needs a bra structure with clearly defined inner and outer layers, integrated weaving, no glue bonding, a soft and skin-friendly inner layer, and an outer layer that combines health benefits and support. Based on this, this invention proposes a double-layer integrated far-infrared health bra. Summary of the Invention

[0003] This invention aims to solve the technical problems of existing bra products, such as complex manufacturing processes, easy delamination, and difficulty in balancing comfort and health care functions. It provides a double-layer, one-piece woven far-infrared health care bra, achieving a double-layer, one-piece woven design for the bra cups without the need for glue bonding or hot-pressing composite processing. The inner skin-contact layer is extremely soft and skin-friendly, non-irritating, and has high elongation to meet the needs of close-fitting wear. The outer functional layer provides both far-infrared health care and structural support, achieving the purpose of breast care while also possessing strong antibacterial properties to ensure hygiene and safety of the wearing area. The functions of the inner and outer layers are clearly defined, and the overall fabric is lightweight, moisture-wicking, breathable, and resistant to deformation and delamination, making it suitable for direct use as a bra cup.

[0004] Therefore, the present invention provides a double-layer integrated far-infrared health bra, including a bra body, wherein a cup body is connected to the inner side of the bra body; the cup body adopts a double-layer integrated woven structure, which is formed by knitting an inner skin-contact layer and an outer functional layer in one step using a knitting device; the inner skin-contact layer and the outer functional layer are uniformly connected by dot-shaped bonding tissue, without glue bonding and without secondary processing steps.

[0005] Furthermore, the inner skin-contact layer is a blend of mulberry fiber and modal fiber in a weight ratio of 30:70. Mulberry is a fiber extracted from the bark of the mulberry tree. In addition to having the excellent moisture absorption and breathability properties of general bast fibers, it is also a high-quality variety of bast fibers that is soft, has a high elongation rate, and is skin-friendly and non-irritating, ensuring a comfortable feel when worn close to the skin.

[0006] Furthermore, the outer functional layer is a blend of Apocynum venetum fiber and Modal. Among them, Apocynum venetum is the only existing textile fiber that meets the national standards for far-infrared emitting materials. It can achieve far-infrared health care and support the main structure of the bra cup, while also having excellent natural antibacterial properties, effectively ensuring the hygiene and safety of the wearing area.

[0007] Furthermore, the inner skin-adhesive layer is specifically designed for comfortable contact with the body and does not provide any health benefits.

[0008] Furthermore, the outer functional layer is specifically responsible for far-infrared health care and structural support, and does not come into direct contact with the skin.

[0009] Furthermore, the double-layer integrated woven structure is woven as a whole using a double-sided knitting machine or a fully formed knitting device, with different yarn materials for the inner and outer layers, resulting in different functional effects.

[0010] Furthermore, the dotted bonding tissue is evenly distributed, ensuring a firm connection between the inner skin-adhesive layer and the outer functional layer, preventing delamination, deformation, and irritation to the skin.

[0011] Furthermore, the cup body is integrally molded, thin and breathable, and can be directly used in the production of finished bras.

[0012] Furthermore, the bra body has an elastic shoulder strap connected to the outside, a fastening block connected to the right end of the bra body, and a connecting block installed on the left end of the bra body. The fastening block and the connecting block cooperate with each other to facilitate wearing and tightness adjustment.

[0013] Compared to existing technologies, the advantages of this invention are: 1. Environmentally friendly process and stable structure: The main body of the cup adopts a double-layer integrated weaving process, which achieves a firm connection between the inner and outer layers through point-joint structure. There is no need for glue bonding or secondary hot pressing processing, which completely solves the problem of easy delamination and deformation of traditional composite bras. At the same time, it avoids skin irritation caused by glue residue and improves wearing safety.

[0014] Optimized wearing experience: The inner skin-contact layer is made of a 30:70 blend of hemp and modal, which combines moisture absorption and breathability with an extremely soft texture that is gentle on the skin and does not cause itching. This solves the problems of itching and poor comfort of traditional hemp fibers, and the high elongation further improves the fit.

[0015] Combining health benefits and support: The outer functional layer is made of a blend of hemp and modal, which, relying on its natural far-infrared emission properties that meet national standards, provides far-infrared care for the chest and promotes local blood circulation. At the same time, thanks to the structural strength of the fibers themselves, it provides reliable support for the cups and, combined with its natural and powerful antibacterial properties, inhibits bacterial growth and ensures hygiene of the wearing area.

[0016] Production and Wearing Convenience: The cup body is molded in one piece without any extra splicing structure, making it lightweight and breathable, reducing the feeling of stuffiness when wearing it; it can be directly used for the production of finished bras, simplifying the production process, improving production efficiency, and reducing manufacturing costs; with elastic shoulder straps and a detachable fastening structure, it is easy to wear, can fit people of different body types, and improves wearing stability.

[0021] The present invention provides the following embodiment of a double-layer integrated far-infrared health care bra: First Embodiment Combination Figs. 1-2 This embodiment discloses a double-layer integrated far-infrared health care bra, including a bra body 1. The bra body 1 is made of conventional elastic knitted fabric and is cut and sewn. Its inner side is fixedly connected to the cup body 2 by a sewing process.

[0022] The main body of the bra cup 2 is woven in one piece using a fully formed knitting machine, forming a double-layer integrated structure, specifically including an inner skin-contact layer 3 and an outer functional layer 4. The inner skin-contact layer 3 is a blend of mulberry fiber and modal fiber in a weight ratio of 30:70. The mulberry fiber is extracted from the bark of the mulberry tree. Compared with ordinary bast fibers, it has better softness and elongation, and outstanding breathability and moisture absorption. It does not cause itching or tightness when worn close to the skin, ensuring wearing comfort. The outer functional layer 4 is a blend of Apocynum venetum fiber and Modal fiber. Apocynum venetum is the only natural fiber among existing textile fibers that does not require chemical modification and meets the national standards for far-infrared emitting materials. It can achieve far-infrared health benefits and provide structural support for the main body of the bra cup 2, taking into account both support and breathability. According to the test, the Apocynum venetum fiber has an antibacterial rate of 99% against Staphylococcus aureus, an antibacterial rate of 98% against Escherichia coli, and an antibacterial rate of 96% against Candida albicans. It can effectively inhibit the growth of common pathogenic bacteria in underwear and ensure the hygiene and safety of the wearing area.

[0023] During the weaving process, a special stitch design on a double-sided knitting machine or a fully formed knitting device creates a uniformly distributed dotted bonding structure 5 between the inner skin-contact layer 3 and the outer functional layer 4. The yarn interlacing length at the bonding point is controlled at 2-3 mm, ensuring a firm connection between the two layers, preventing delamination and deformation, while also avoiding bumps or chafing at the bonding point. In this embodiment, the inner skin-contact layer 3 is only responsible for comfortable contact with the skin and does not provide health benefits; the outer functional layer 4 does not directly contact the skin and focuses on providing far-infrared health benefits and structural support. The functions of the inner and outer layers are clearly defined, and their performance does not interfere with each other.

[0024] Second Embodiment This embodiment further optimizes the overall structure of the bra based on the first embodiment. The cup body 2 adopts a one-piece molding process, and the fabric is thin and breathable, requiring no additional composite processing. It can be directly used for sewing finished bra products, greatly simplifying the production process. At the same time, elastic shoulder straps 6 are sewn to the outside of the bra body 1. The right end of the bra body 1 is fixed with a fastening block 7, and the left end is installed with a connecting block 8. The fastening block 7 and the connecting block 8 are connected by a snap-fit, which can realize quick wearing and tightness adjustment, adapting to users with different bust sizes and body shapes, and improving the bra's fit and stability.

[0025] In summary, the double-layer integrated far-infrared health bra disclosed in this invention achieves glue-free and heat-press-free composite molding through a double-layer integrated weaving process, solving the defects of traditional bra manufacturing processes; the inner layer is skin-friendly and comfortable, while the outer layer provides health support, with a clear division of functions, combining a comfortable wearing experience with practical health benefits, and its overall performance is superior to existing similar products.
