Problems solved by technology

However, the mechanical strength of the film itself is low. For example, if it is used in push-up bras and other products that generate a large force when used, the film is easily deformed by force, so that the bra cannot produce the desired effect of supporting and gathering the breasts.
However, the flat and narrow film has a small load-bearing area, and the pressure on the breast cannot be eliminated. Long-term wearing can easily damage the breast tissue, making some areas red, swollen or even ulcerated.
The existing non-wire bras on the market are basically non-marking half-piece bras. The production process and materials determine that the non-marking half-piece bras have no steel rings, are easy to move, are airtight, and are easy to deform after washing.
In addition, most of the existing mold cups are filled with PU foam sponge made of polymer materials. The sponge has the following disadvantages: 1) The PU sponge is made of foam after chemical reaction, and its unstable chemical structure is difficult to process when the cup is processed. Toxic substances will be emitted during the process or worn by the human body, which will cause certain pollution to the environment and have certain adverse effects on the human body; 2) After the sponge body is shaped and processed, the original loose structure becomes dense, which greatly reduces the air permeability of the product and affects The wearing comfort of the sponge cup is improved; 3) The chemical yellowing and aging phenomenon will occur after the sponge product is placed for a long time, which will affect the appearance and performance of the product
It has been verified that the process of preheating the vertical fiber cotton at a high temperature of 200-300 ° C is very easy to destroy the honeycomb structure of the vertical fiber cotton, reducing the air permeability and elasticity of the vertical fiber cotton

Embodiment 1

[0045] This embodiment provides a kind of upright fiber cotton mold cup without rims, such as figure 1 , including a mold cup body 1 and a 3D support 2 arranged at the bottom of the mold cup body. Such as figure 2 , the 3D support includes a longitudinally arranged reinforcing surface 21 and a concave supporting curved surface 22 formed by extending forward from the top of the reinforcing surface. The reinforcing surface and the supporting curved surface are connected by a smooth intermediate curved surface 23 .

[0046] The included angle between the reinforcing surface 21 and the lateral projection of the supporting curved surface 22 is 120°.

[0047] Such as image 3 , the forward projection of the supporting curved surface is a smooth concave curve, and the curvature of the curve increases from the outside of the mold cup to the inside of the mold cup. In addition, the forward projection of the supporting surface can also be set as an arc, and the 3D support can be ti...

[0066] b. the sandwich fabric layer of the surface layer is put into a surface layer mould, and it is preheated and pressed;

[0067] c. covering the surfaces of the surface layer and the inner layer with thermal adhesive respectively;

[0068] d. enter the inner layer, the upright fiber cotton layer, the strip sheet, and the surface layer into a mold cup mold successively and position them;

[0069] e. hot pressing each raw material in the mold cup mold to obtain a rough mold cup;

[0070] d. Place the rough mold cup in a cold press mold cup mold for cold pressing;

[0071] e....

Embodiment 3

[0078] This embodiment provides a molding method of the mold cup in Embodiment 1.

Abstract

The invention discloses a vertical fiber cotton steel-ring-free mold cup, molding of the mold cup and a splitting type steel-ring-free bra. The mold cup is internally provided with a 3D supporting piece, and a supporting curved surface is matched with a reinforcing surface so that the stability is relatively high; and particularly, the supporting curved surface has relatively large stressing area so that the oppressing sensation on breasts by the bra can be effectively eliminated and the comfort of wearing the bra is improved. The mold cup has excellent supporting and gathering effects on the breasts; and when a user wears the bra with the mold cup, the shape of the breasts can be remarkably improved and the body curve of the wearer is modified.

Description

technical field [0001] The invention relates to a mold cup and a bra, in particular to an upright fiber cotton no steel ring mold cup, a forming method of the mold cup and a split type no steel ring bra. Background technique [0002] Bras generally include two symmetrical mold cups. The mold cup is a cup-shaped body that protrudes from the inner layer to the outer layer. The shaping ring for the second half of the cup. The shaping ring is usually made of metal materials such as steel, so it is often collectively referred to as a steel ring. The underwire has the advantages of high mechanical strength, strong load-bearing capacity, and good shaping effect on the chest. Wearing a bra with an underwire helps maintain the curve of the chest. However, the load-bearing area of ​​the steel ring is small and the rigidity is high. Long-term wearing will compress the breast tissue, hinder blood circulation and damage human health. At the same time, bras with steel rings often have ...
