Abstract: A method for manufacturing nanofibers, according to the present invention, supplies a spinning solution comprising one selected from a polymer solution and a polymer melt in a spinning tube, which has one shape selected from a cylindrical shape and a conical shape, in which one shape selected from a groove or a protrusion is formed on the inner surface thereof; and spins the spinning solution in a nanofiber shape by centrifugal force generated from rotating the spinning tube at 3,000 rpm or higher, while gas is discharged toward a collector which is installed in an upper part higher than the spinning tube, through a tube for spraying gas which is installed outside the spinning tube, thereby concentrating the spun nanofibers on the collector. The present invention decreases the viscosity of the polymer melt by a high shearing force without the decomposition of the polymer by using only pure centrifugal force without electrostatic force, thereby manufacturing nanofibers from the polymer solution and the polymer melt with high productivity (discharge amount). Moreover, the present invention does not use existing spinning nozzles, so replacement and cleaning of nozzles are not required, and high voltage is not applied to the collector, therefore work risk is deceased, and drops are effectively prevented.

Abstract: A material for a cosmetic mask according to the present invention has a bilayered structure of a nanofiber membrane (2) composed of nanofibers and laminated on a fabric (1). A facial skin care method according to the present invention comprises the steps of: settling the material for a cosmetic mask (A) having the bilayered structure of the nanofiber membrane (2) composed of nanofibers and laminated on the fabric (1), on a mask (B) for blocking ultraviolet rays and dust so that the fabric (1) can come in contact with the inner surface of the mask (B) for blocking ultraviolet rays and dust; spraying cosmetic liquid onto the nanofiber membrane (2) of the material for a cosmetic mask (A), attached to the inner surface of the mask (B) for blocking ultraviolet rays and dust; and attaching the nanofiber membrane (2) sprayed with the cosmetic liquid onto a face. The cosmetic mask shows long-term skin care effects by spraying only a small amount of the cosmetic liquid instead of impregnating the material for a cosmetic mask with a large amount of cosmetic liquid owing to the long-term retention ability for cosmetic liquid. Accordingly, the present invention facilitates indoor and outdoor activities with a cosmetic mask made of the material for a cosmetic mask according to the present invention because cosmetic liquid does not ooze out from the cosmetic mask even if a user does indoor and outdoor activities with the cosmetic mask on.
