Description

TECHNICAL FIELD

The present invention relates to the technical field of clothing, specifically to a women's bra, in particular to a bra with a wide under band hem and a manufacturing method thereof.

BACKGROUND

A bra mainly comprises cups, wings and shoulder straps. A center front is provided between the two cups. The center front mainly controls the center distance, and connects the cups, so that the cups are not easily displaced; the wings generally includes the side wings and back wings, which are used to accommodate the rib fat and help support the breasts; the cups are mainly used to accommodate the breast fat and shape the breast curve. Generally, a under band hem is provided on the lower side of the wings, and its main function is to support and fix the position of the bra, making it more stable, fit and comfortable to wear.
At present, the under band hems of the bras on the market have different widths. Generally, it is laid on the inner side of the under bust, side wings and back wings with the reverse & sequential binding and flat laying method, and its upper edge is generally continuously connected with the under bust. The width of the under band hem is generally set so that its upper edge can be connected with the lower edge of the cups or the wire casings. As shown in FIG. 1-3, the traditional reverse & sequential binding and flat laying method mainly includes the following steps: First, as shown in FIG. 1, connect the center front, under bust and back wings through single-needle stitching; second, as shown in FIG. 2, stitch the under band hem with the herringbone, three-needle or other proper stitching methods; third, as shown in FIG. 3, stitch the cups through single-needle stitching, then locate the wire casings on the bottom cups, and stitch them with the double-needle stitching method.
Bras manufactured with the traditional reverse & sequential binding and flat laying method have the following shortcomings due to the narrower under band hems: First, the stress surface is small, and it is easy to produce the discomfort of wearing tightness; second, the support and stability are poor, particularly, the bra moves and slides when it is worn by consumers with full breasts; third, the existing traditional reverse & sequential binding process makes the breasts cling to the human trunk easily for consumers with full breasts, resulting in stuffiness and airtightness; fourth, the structure is complex, the manufacturing is difficult, and the cost is high.
To solve the above problems, based on the traditional bra structure, the inventor of the present invention tries to overcome the above shortcomings by widening the under band hem. However, the inventor finds that widening of the under band hem can increase the stress surface and supporting force, improve the discomfort of wearing tightness to a certain extent, increase the stability of the bra, and reduce the probability of the bra's dislocation and sliding; however, this widening also brings new problems such as curling and eversion of the under band hem, which affect wearing. In addition, after widening the under band hem, the lower part of the bra fits more closely with the human trunk, and the stuffiness and airtightness are further aggravated.
Therefore, in view of the above situation, it is one of the technical problems to be solved urgently by those skilled in the art to provide a bra with a wide under band hem and a manufacturing method thereof.
