Problems solved by technology

However, this kind of underwear is basically bonded to the sponge cup body by heat pressing, which requires glue, and the heat pressing process requires the decorative layer fabric to completely cover the surface of the mold. After heat pressing, the excess fabric is cut The part that is glued to the sponge cup is left at the end. This process wastes a lot of materials, which is not conducive to the concept of national environmental protection and resource conservation. It will also increase the cost of bras and underwear virtually, and the preparation process is relatively complicated. Glue is used, which has hidden dangers to human health

Embodiment 1

[0047] Such as figure 1 Shown, a kind of preparation technology of bra comprises the following steps:

[0048] Step 1: Prepare a three-dimensional sponge cup by hot pressing.

[0049] Step 2: According to the cross-sectional shape of the mouth of the sponge cup, draw a drawing A that is consistent with its shape and size.

[0050] Step 3: draw drawing B according to drawing A, and drawing B includes a central part 1 which is consistent with the shape and size of drawing A and a peripheral extension part 2 obtained by vertically extending outward along the periphery of central part 1 for a distance H.

[0051] Step 4: According to drawing B, cut out the outer fabric of the sponge cup with the same shape and size as that of drawing B. The outer fabric of the sponge cup is four-way elastic fabric. Place the sponge cup body in the shape when it is worn. The side edge 11, the right edge 10 and the lower arc edge 12 are connected end to end, and the peripheral extension part 2 of ...

Abstract

The invention relates the technical field of bra underwear production, in particular to a production technology of a bra. A drawing A consistent with a sponge cup body in shape and size is drawn according to the cup mouth section of the sponge cup body; a drawing B is obtained according to a peripheral extension part formed by vertically extending the drawing A for a distance H; sponge cup body outer fabric consistent with the drawing B in size is cut out according to the drawing B, the sponge cup body is placed in a wearing shape, the edge of the sponge cup body consists of a left side edge, a right side edge and a lower arc edge which are sequentially connected end to end, and correspondingly, the peripheral extension part of the sponge cup body outer fabric consists a left outer edge, a right outer edge and a lower arc edge which are connected end to end; the front side of the right edge is attached to the back side of the right side edge, sewing is began from the back side of the right outer edge along the right outer edge; the left outer edge is sewn in the same manner, the bra underwear with cup surfaces free of creases is obtained through sewing, the production technology is simple, raw materials are saved, and no harm is caused to human bodies.

Description

technical field [0001] The invention relates to the technical field of making bras and underwear, in particular to a brass preparation process. Background technique [0002] Bra is one of the underwear used by women, its main function is to cover and support the breast. Women's breasts are mostly fatty tissue. The main purpose of wearing a bra is to provide external support for the breasts, increasing comfort and mobility. [0003] In addition to providing the above-mentioned functions, the shape of the bra is also one of the important factors for many women to choose. The structure of conventional bra cups, also known as mold cups, is an inner layer with a skin layer, a sponge layer in the middle, and a decorative layer outside. There are two different ways to connect the decorative layer on the surface of the sponge layer to the sponge layer. One is to heat press and shape the sponge layer and then cut it out. The other is to sew it outside the sponge cup. The front is...
