Abstract:
The present invention relates to a puff for both liquid and powder cosmetics and a method for manufacturing the same. Specifically, provided are a puff for both liquid and powder cosmetics and a method for manufacturing the same, in which the puff is manufactured in such a manner that after a pile of polyester fabric is cut to adjust the length of the pile, the polyester fabric is bonded to a urethane sponge with a urethane adhesive so as to form a waterproof layer on the urethane sponge without laminating a waterproof layer on the urethane sponge while preventing the polyester fabric from flowing, such that a sheet is manufactured so as to apply a cosmetic material with a high adhesion, and then the edges of the sheet are sealed by ultrasonic fusion and cut so as to prevent the cosmetic material from penetrating into the inside and the side of the puff. According to the puff and the manufacturing method of the present invention, the puff can be used for both liquid and powder cosmetics, and a cross-sectional thickness of the puff and the size of a cut line of the puff can be reduced and the cosmetic material and skin oils are prevented from penetrating into the urethane sponge. In addition, since the polyester fabric does not flow, the cosmetic material is applied with a high adhesion, the productivity of the puff is improved, and the production cost of the puff is reduced.
