Method for manufacturing core-material-containing garment, and core-material-containing garment

A method for manufacturing a core-material-containing garment by using a core material configured to alter a body shape, the method comprising:

• a linear core material application step of applying a reactive hot-melt adhesive to one piece of fabric linearly and cured to form the core material to be used for a brassiere or waist nipper, the hot-melt adhesive being a moisture curable type;
• an adhesive application step of applying a bonding hot-melt adhesive configured on a table, to bond the piece of fabric in which the linear core material is formed and another piece of fabric;
• and
• a drying step of drying the applied bonding hot-melt adhesive,
• wherein the adhesive application step, the bonding hot-melt adhesive is applied to the piece of fabric avoiding the formed core material, and then the other piece of fabric is superimposed on the formed core material, to prevent the formed core material from adhering to the other piece of fabric.
