Description

Technical Field

[0001] The present invention relates to the technical field of bra manufacturing, and particularly to a crystal bra with a glass yarn composite fabric. Background Art

[0002] A bra is a type of women's underwear, mainly used to support and care for the breasts. The design and function of modern bras have made significant progress, and the color and material options are also increasingly rich. In addition to the basic requirements of comfort and support, people have higher requirements for the aesthetics of bras.

[0003] Most existing bras use cotton and chemical fiber fabrics. Among them, cotton fabrics have good moisture absorption but lack elastic support and are prone to deformation during exercise. Therefore, it is of great practical significance to develop bra materials with better comfort and aesthetics. In addition, in the prior art, the silicone support used in silicone bras is widely used due to its good plastic characteristics, good tensile ductility and recovery. However, the problem is that the silicone material used is not easy to formulate due to its molecular structure. During the processing process, after the color masterbatch is introduced, it is not easy to blend evenly, resulting in local agglomeration, and then the developed image colors are uneven in depth and distribution, affecting the overall aesthetics of the bra. Especially when the outer veil is thin, the appearance of the silicone support cannot match the veil, thus affecting the overall aesthetics, so it urgently needs to be improved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a crystal bra with a glass yarn composite fabric to obtain a bra product with better comfort, support and aesthetics.

[0005] The technical problem to be solved by the present invention is realized by the following technical solutions:

[0006] A crystal bra with a glass yarn composite fabric, comprising a surface layer, a lining layer, and a first support member and a second support member disposed between the surface layer and the lining layer;

[0007] The fabric of the surface layer is composed of a composite of nylon, glass yarn and spandex;

[0008] The fabric of the lining layer is composed of a composite of nylon and spandex;

[0009] The first support member is a silicone support member for supporting the lower part and the outer edge of the breast;

[0010] The second support member is a curved support member made of a breathable material for covering and supporting the front part of the breast;

[0011] A receiving area is provided in the first support member; the second support member is disposed in the receiving area.

[0012] Further, the fabric of the surface layer comprises 75-80% nylon, 10-15% glass yarn, and 5-10% spandex. The fineness of the nylon and spandex is 65-75D, and the fineness of the glass yarn is 18-22D. The fabric of the surface layer is processed by a warp knitting four-shuttle machine.

[0013] Further, the fabric of the inner layer comprises 55-60% nylon and 40-45% spandex. The fineness of the nylon and spandex is 65-75D.

[0014] Further, the first support member includes a bottom supporting strip and two side supporting strips that are oppositely arranged and integrally formed with both sides of the bottom supporting plate. The abutting surfaces of the bottom supporting strip and the side supporting strips with the breast are both set to be arc-shaped adapted to the edge of the breast. The bottom supporting strip is further provided with supporting points protruding from the surface of the bottom supporting strip.

[0015] Further, the thickness of the side supporting strip gradually increases from the top to the bottom.

[0016] Further, the two second support members in the accommodating area are independent of each other and oppositely arranged. The second support member is a high-density sponge mold cup with a density ≥ 35 kg / m 3 of the high-density sponge.

[0017] Further, the second support member includes an upper edge arc-shaped protruding portion and an integrally formed downwardly tapered pendant portion. The bottom of the pendant portion is detachably and fixedly connected to the bottom supporting strip.

[0018] Further, the preparation method of the silicone support member includes the following steps:

[0019] 1) Color masterbatch pretreatment: The color masterbatch and the silane coupling agent are premixed at a mass ratio of 1:3-5 to form surface-modified color masterbatch particles;

[0020] 2) Vinyl silicone oil synthesis: Using silicon ore as the raw material, adding carbon to reduce it to metallic silicon at high temperature, adding a catalyst to the metallic silicon, reacting to generate siloxane cyclic bodies, and synthesizing vinyl silicone oil using the siloxane cyclic bodies as the raw material;

[0021] 3) Kneading: Premix vinyl silicone oil and fumed silica at 40-60 °C and a vacuum degree of -0.08 MPa for 10-15 minutes, then add the pretreated color masterbatch, and add hyperbranched polysiloxane accounting for 0.5-2 wt% of the mass of the color masterbatch, raise the temperature to 80-100 °C, and continue kneading at a rotation speed of 30-50 rpm for 20-30 minutes;

[0022] 4) Fixing the color: Using ultraviolet light with a wavelength of 365 nm and an intensity of 50-100 mW / cm2 to assist in vulcanization to obtain a silicone material, and further processing the silicone material to obtain a silicone support member.

[0023] Beneficial effects: The crystal bra with a glass yarn composite fabric according to the present invention has a surface layer that presents different crystal-like shiny effects with different light and viewing angles, greatly improving the aesthetics. Combining the settings of the first support member and the second support member, the prepared bra is beautiful, light, thin, breathable, comfortable to the touch and elastic, while achieving a good balance of static support, dynamic comfort, and health and environmental protection.

[0024] For the crystal bra with a glass yarn composite fabric according to the present invention, the first support member is a silicone material treated specially. During the processing of the silicone material, a color masterbatch surface modifier and a hyperbranched dispersant are combined, and a process of segmented kneading and ultraviolet curing is adopted, so that the color masterbatch in the silicone material is evenly distributed and well cured. In practical applications, even if the surface layer fabric is light and translucent, a support member made of a silicone material with a matching color can be selected according to needs, ensuring the support effect without affecting the aesthetics.

[0052] Comparative Example 1

[0053] The crystal bra with a glass yarn composite fabric described in this comparative example includes a surface layer, a lining layer, and a first support member and a second support member disposed between the surface layer and the lining layer.

[0054] Among them, the fabric of the surface layer is composed of a composite of nylon, glass yarn, and spandex. Specifically, the fabric of the surface layer includes 78% nylon and 22% spandex, and the fineness of the nylon and spandex is 70D. The fabric of the surface layer is processed by a warp knitting four-shuttle machine with nylon and spandex. After the surface layer fabric is processed, it is relatively comfortable but has no crystal glitter effect and is relatively ordinary. The fabric of the lining layer is composed of a composite of nylon and spandex; specifically, the fabric of the lining layer includes 59% nylon and 41% spandex, and the fineness of the nylon and spandex is 70D. The lining layer is comfortable, breathable, and has good abrasion resistance.

[0055] The structures of the first support member and the second support member are the same as those in Example 1.

[0056] In this embodiment, the silicone support member is prepared from a specific silicone material, and the preparation method of the silicone support member includes:

[0057] 1) Synthesis of vinyl silicone oil: Using silicon ore as the raw material, adding carbon and carrying out a reduction reaction in an electric arc furnace at 2800 °C to form metallic silicon, and obtaining metallic silicon with a purity of 99.1%; directly synthesizing methylchlorosilane from metallic silicon and chloromethane (CH3Cl) under a copper catalyst, and then hydrolyzing to generate siloxane ring bodies, and synthesizing vinyl silicone oil from the siloxane ring bodies as the raw material;

[0059] In this embodiment, the color difference of the prepared first support member is greater than 2 (CIE Lab standard), and there are many obvious color clusters visible to the naked eye, and their distribution is chaotic, with a relatively poor appearance. Moreover, the tensile strength is 2.3 MPa, the elongation at break is 12%, and the resilience rate is 56%. The color difference ΔE from the sky-blue surface fabric is 4.2. Therefore, the first support member cannot be fused with the surface fabric.
