The bra base fabric is made of high-elastic ice silk fiber or ultra-fine modal. The mold cup and bra base fabric are pre-bonded using low-temperature hot melt adhesive (melting point ≤ 80°C); S2. Place the pre-bonded material in the mold, set the temperature to 160-180°C, the pressure to 5-8 MPa, and hot press for 20-30 seconds to melt and combine the layers to form a three-dimensional cup shape in one step. At the same time, a TPU support strip (71) is embedded in the hot pressing process. The support strip (71) is distributed in a "W" shape, extending along the lower edge and side wings of the cup (2) and fixed to the bottom of the cup by secondary molding; S3. The rear elastic band (72) is bonded to the rear portion (4) by a low-temperature hot melt adhesive (melting point ≤ 80°C), and the front fabric of the cup for connecting the shoulder straps is bonded to both sides of the front of the cup by a low-temperature hot melt adhesive (melting point ≤ 80°C), so that the shoulder straps are connected to the cup (2); S4. The side connecting belt (61) is sewn to the side ratio (3) and the rear ratio (4), respectively, and ensures that the notch (62) and the elastic band (63) are in an upward direction; S5. Sewing the two lace edge cords (52) to the edges of the lace decorative fabric (51) respectively, and leaving a certain length of extension adjustment cord (53) at the heart position of the lace decorative fabric (51), sewing and fixing the end of the lace edge cord (52) away from the extension adjustment cord (53) to the side connecting belt (61), sewing and fixing the lace edge cord (52) at the top of the lace decorative fabric (51) to the shoulder strap, and sewing and fixing the connection between the lace edge cord (52) and the extension adjustment cord (53) to the edge of the cup (2); S6. Insert the two extension adjustment cords (53) into the buckle body (541) fixed to the back of the decorative bow (549), insert them through the side holes (542) of the buckle body (541), and exit through the lower hole (544). Press the fixing clip (543) downward to fasten the extension adjustment cords (53) to the buckle body (541); S7. Sewing a row of hooks and a row of buckles at the ends of the two back parts (4) respectively, and inserting the connecting buckles of the shoulder straps into the connecting holes of the back parts (4) to complete the assembly and production of the bra.
