Abstract
A method for manufacturing a functional seamless soft bra-cup involves providing material sheets, heating, forming a first protective sheet, forming a second protective sheet, and finalizing a final product as the functional seamless soft bra-cup. A mold and a vacuum forming machine are first used to form plane material sheets into a first protective sheet and a second protective sheet. The first and second protective sheets are shaped according to a cavity of the mold. Functional material pieces are arranged between the first and second protective sheets. Then the mold and a heating device are used to bind the first and second protective sheets through high-frequency welding into the seamless soft bra-cup, which well fits a wearer's body profile and ensures wearing comfort.
