Description

Back button of underwear

Technical Field

The utility model relates to the field of clothing, especially, relate to an underwear back dunk.

Background

As one of the essential important clothes, the brassiere has become one of the modern people, and with the continuous improvement of living standard, people also pay more attention to the wearing comfort and aesthetic degree of the brassiere while pursuing the practicability and functionality of the brassiere.

The back buckle of the bra of the prior art is the most common after-buckle type, and specifically, the back buckle of the bra of the after-buckle type comprises a clasp part and a ring part, wherein the clasp part and the ring part are respectively sewn on two straps of the bra, and a wearer can realize the fixation of the bra wearing by engaging the clasp part and the ring part, wherein the clasp part is provided with a row of clasps, the ring part is provided with a plurality of rows of rings, and the wearer can realize the adjustment of the tightness degree of the bra wearing by engaging the clasp of the clasp part with the rings of different rows of the ring part.

Due to the particularity of the brassiere structure, in the manufacturing process, only two main processes of fabric cutting and sewing cannot be performed like the conventional clothes manufacturing, generally speaking, manufacturers who manufacture bras on a large scale usually divide the manufacturing process of bras according to the structure of the bras, rather than integrally manufacture the ready-made bras. The method can be divided into three parts of manufacturing of bra cups, manufacturing of bra shoulder straps and manufacturing of bra back buckles in a simple way, and finally the bra cups, the bra shoulder straps and the bra back buckles are connected to complete the manufacturing of the bra ready-made clothes. In the process that the bra is worn, the stress on each part of the bra should be uniform to form good support for the chest of a wearer, so the structural stability of the bra is particularly important, but because the bra is not manufactured in an integrated manner, the strength of the connection of each part of the bra directly affects the structural stability of the bra, in other words, when the mutual connection between certain parts in the bra is in a problem, the chest support of the bra to the wearer is directly affected, for example, when the bra back buckle is not firmly connected with the bra back buckle, the parts are separated or even separated from each other under the stress, and further the support of the bra to the wearer is insufficient or even falls off, the wearing feeling of the wearer is seriously affected, and therefore, the degree of the connection firmness of the bra back buckle and the bra back buckle is very important.

In the prior art, the brassiere back fastener is generally connected to the brassiere back strap through a sewing process, but the brassiere is used as a piece of underwear, and a seam generated by sewing the brassiere back fastener and the brassiere back strap can rub against the skin of a wearer to cause discomfort of the skin of the wearer.

That is, due to the particularity of the structure of the bra, the manufacturing of the bra needs to be divided according to the structure, so the connection firmness degree between the various parts of the bra directly affects the quality of the bra, particularly the connection firmness degree between the bra back buckle and the bra back band, when a wearer wears the bra, the hooks of the bra back buckle are engaged with the loops of one row of the loops, so that the bra is worn at the size of the proper wearer, at the moment, the bra back buckle and the bra back band provide main supporting force, when the connection between the bra back buckle and the bra back band is not firm, the bra back buckle and the bra back band are separated or separated from each other under the force, so that the prior art cannot meet the requirement of the wearer for ensuring the connection firmness degree between the bra back buckle and the bra back band in a sewing manner, however, the sewing thread generated by the sewing can seriously affect the wearing comfort of the wearer, and cannot meet the requirement of the wearer's wearing comfort, and the sewing thread cannot ensure the long-term wear of the bra back buckle during the use, and the long-time, and the bra is not damaged by the long-time wearing friction of the bra back buckle.
