Description

The present invention relates to a brassiere manufacturing method, and more particularly to a brassiere that is entirely formed of a stretchable material, fits to a body chest when worn, and is used for sports, leisure, etc. The present invention relates to a method of manufacturing a sports bra useful during exercise or as a foundation underwear pursuing fashion.

[Prior Art] Conventionally, this type of brassiere has been used, for example, for cutting cloth and urethane pads, ground stitching, stitching, pad alignment, pad mounting, padding with two needles, side band mounting, upper side and hem stitching, and hooking. It is manufactured through many detailed processes such as.

However, such a conventional method for manufacturing a brassiere has a problem that the manufacturing process is complicated over a wide range, and the manufacturing cost is high.

[Problems to be Solved by the Invention] The present invention has been devised in view of the above point of view, and provides a method of manufacturing a sports bra which fits well on the body, and which can be manufactured simply and inexpensively. To provide.

[Means for Solving the Problems] That is, the present invention forms a rectangular cloth piece having a folded portion at one end in the length direction with a cloth which can be stretched at least in the width direction, and this rectangular cloth piece is formed by the folded portion. And sewn along the both side edges to form a bag-like cloth piece. Then, on the folded side of the bag-like cloth piece, a collar is provided at the approximate center in the width direction of the bag-like cloth piece. The present invention is a method of manufacturing a sports bra in which sleeves are formed on each side and a pad is inserted and fixed between the above-mentioned folded portion and a chest outer fabric positioned on the front side thereof.

In the method of the present invention, the fabric used for the production of the brassiere must be a fabric that can be stretched at least in the width direction, and specifically, cotton, silk, polyester, nylon, ethylene tetrafluoride fiber, or these. And knitted fabrics such as plain knitted, rubber knitted, and pearl knitted, and dart knitted fabrics, etc., and are preferably knitted fabrics that can expand and contract in the front-rear and left-right directions.

The rectangular cloth pieces formed using these stretchable fabrics vary in length depending on the stretchability of the fabrics, the height of the wearer, etc. The width dimension is about half the length around the chest of the human body, and the size of the folded part, that is, its vertical dimension, can cover the female breast It is as large as possible, and it is preferable to form one squeezed portion in the longitudinal direction of the center, and to improve the fit by positioning it at the center of the left and right breasts when worn. If the rectangular cloth piece is knitted other than rubber knitting, the end of the folded portion and the end on the other end side, which form the lower peripheral edge when the brassier is formed, are formed. A rubber knitting margin having an appropriate width, for example, about 0.5 to 4 cm, preferably about 1 to 3 cm may be formed along the edge, thereby improving the fit to the chest of the human body. Further, the turning direction of the turning portion may be inside or outside.

In forming such a rectangular cloth, for example, a long cloth having a width dimension equal to the length of the rectangular cloth piece and having a predetermined folded portion along one side edge is formed. Then, it may be formed by cutting it into a dimension equal to the width dimension of the rectangular cloth piece, or by cutting a cylindrical cloth knitted in a cylindrical shape and having a folded portion at one end opening side in the longitudinal direction. It may be formed.

Further, when such a rectangular cloth piece is formed, a stretchable cloth may be formed once, a folded portion or the like may be formed from the stretchable cloth, and cut into a predetermined size. This rectangular cloth may be knitted at the same time as knitting the folded portion, the squeezed portion, the rubber knitting margin, and the like.

The rectangular cloth piece formed in this manner is then folded in two so that the edge of the return blow coincides with the edge on the other end so that the return portion is next to the inside, and each side edge portion thereof is A stitched fabric piece is formed. At this time, both side edges of the folded portion are simultaneously bound to form an inner pocket inside the bag-like cloth piece, which opens in the direction opposite to the opening direction of the bag-like cloth piece.

Next, the bag-shaped cloth piece is formed with a neckline on its folded side and a sleeve around each of the binding margins, and a pad is provided between the folded part and the chest outer fabric positioned on the front side thereof. It is inserted and fixed. In this procedure, either the formation of the neck and sleeves and the pad fixing may be performed first, but it is preferable that the formation of the neck and sleeves be performed first, and then the pad mounting and fixing be performed. Good. In addition,
The neck and sleeves should be overturned to prevent fraying at the cut points.

Further, as for the means for fixing the pad between the folded portion and the chest surface material located on the front side thereof, the pad is fixed by sewing, bonding, hook-and-loop fastener, etc., and the folded portion and the chest surface material on the front side are fixed. Can be performed by means such as forming a bag-like portion between them and charging the bag-like portion.
The pad may be pressure-fixed by means of a press or the like using an appropriate adhesive such as an A-based emulsion adhesive. When the pad is fixed, the folded portion and the chest outer surface on the front side thereof are simultaneously fixed.

Furthermore, in the method of the present invention, appropriate dyeing may be performed at an appropriate point in the manufacturing process, for example, before and after the production of rectangular cloth pieces or before and after the production of bag-shaped cloth pieces.

[Operation] According to the method of the present invention, the troublesome work of molding a large number of cloth pieces from an elastic cloth and sewing and tailoring the cloth pieces becomes unnecessary, and the fine work is eliminated, so that factory production is eliminated. Becomes easier.

EXAMPLES Hereinafter, the method of the present invention will be specifically described based on examples.

First, as shown in FIG. 1, using a knitting machine, the knitting is knitted into a cylinder having a size of about 60 cm in length × about 30 cm in circumference, and has a folded portion 2 on one end opening side. Is shown a stretchable cylindrical fabric 1.
