(3) on sticking locating back mould, force together the brassiere main body is sticking by following step:

(a) two layers of base fabric is tiled on the counterdie of sticking locating back mould;

(b) after utilizing infrared ray to demarcate the position on the base fabric, put the elastomer at cup position;

(c) utilize infrared ray to demarcate that steel ring, heart cloth, stereotypes yarn are put in the position, the back of the body is buckled and bond paper;

(d) put two aspect cloth, depress sticking locating back upper mould the sticking together pressure of cup main part;

(4) on the thermocompression forming mould, brassiere tow sides thermocompression forming is become the desired shape of cup;

(5) the ultrasonic wave cutter is cut out;

(6) make double-colored shoulder belt, BAR-TACK or welding shoulder belt make shoulder belt be connected with the brassiere main body.

Can both wear by the prepared brassiere tow sides of preparation method of the present invention, tow sides have different colors, and do not have sewing and splicing.Preparation method of the present invention is reasonable, and is simple, can guarantee product quality.

Description of drawings

Fig. 1 is the front view of reversible bra of the present invention.

Fig. 2 is the rearview of reversible bra shown in Figure 1.

Fig. 3 is the back of the body button schematic diagram of reversible bra shown in Figure 1.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, brassiere involved in the present invention comprises: cup 1, flank 2, back of the body button 3, shoulder belt 4.The brassiere front is the A look, and reverse side is the B look, and the positive and negative profile is identical, and whole brassiere is one-body molded except that shoulder belt, no sewing and splicing.

Brassiere is formed by five layers, first and second the layer and fourth, fifth layer be cloth, middle one deck is the elastomer at the cup position.

During making:

(1) utilize 3-D technology to make thermocompression forming patrix and thermocompression forming counterdie.

(2) utilize 3-D technology to make sticking locating back patrix and sticking locating back counterdie.

(3) on sticking locating back mould, force together the brassiere main body is sticking by following step:

(a) two-layer bright and beautiful spandex cloth is tiled on the sticking locating back counterdie as base fabric.

(b) put the elastomer at cup position after utilizing infrared ray to demarcate the position on the base fabric, the elastomer at cup position is the thick sponge in the 2mm left and right sides.

(c) utilize infrared ray to demarcate that steel ring, heart cloth, stereotypes yarn are put in the position, the back of the body is buckled and bond paper then, heart cloth is positioned at brassiere heart position 5, heart cloth can be avoided heart position 5 to be elongated in washing and dress causing brassiere distortion, wear no longer fit; Stereotypes yarn is positioned at brassiere side folder position 6, play side folder position 6 is unlikely to owing to the pulling repeatedly of flank 2 and shoulder belt 4 is out of shape, also play the softer effect of an end of the steel ring that makes side folder position 6, be unlikely to allow the protruding injured skin of steel ring end, or allow skin not feel well; Bond paper is used for brassiere back of the body buckle and the brassiere flank is buckled clamped position with the back of the body, and the cloth of this position, two places can not turned up owing to not carrying on the back the use of buckleing.

(d) put two-layer bright and beautiful spandex face cloth at last, depress sticking locating back patrix the sticking together pressure of integral body;

(4) on the thermocompression forming mould, brassiere tow sides thermocompression forming is become the desired shape of cup, during thermocompression forming, 150-200 ℃ of thermocompression forming patrix temperature, 150-200 ℃ of thermocompression forming counterdie temperature, about 7.5 seconds of front thermocompression forming, reverse side be about 7.5 seconds of thermocompression forming also.

(5) brassiere after will finalizing the design with the ultrasonic wave cutter is cut into the brassiere main body.

(6) make double-colored shoulder belt, BAR-TACK or welding shoulder belt make shoulder belt be connected with the brassiere main body.

As shown in Figure 3, back of the body button 3 is a buckle, and flank 2 is provided with opening with back of the body button clamped position.When dressing brassiere, no matter be that wear in the front or reverse side is worn, only flank 2 and the opening part that the opening of carrying on the back the button clamped position snaps in back of the body button 3 need be got final product.Do not meet the problem of people's dress custom when having avoided adopting counter the wearing that fastener brings, because for the brassiere that launches, when adopting fastener, in order to meet people's dress custom, the left side is button, and the right is a hook, can work as when anti-one side is worn, be buckled in the right, be hooked in the left side, wear inconvenience.

The brassiere that the present invention relates to is by the mould manufacturing, and about sponge 2mm, the thickness of four layers of cloth is near 3mm, and the brassiere after the moulding is 2-2.5mm, can satisfy the requirement that the two sides can both be worn.
