Abstract: A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in at least a portion of the surface thereof, an electroconductive section having a surface electrical resistivity of 1011 Ω/cm2 or less, or a hydrophilic section having a water contact angle of preferably from 15° to 90° at 25° C. A user collects, with the fiber collection tool, a fiber spun by the user by electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.

Abstract: A fiber collection tool for collecting a fiber spun by electrospinning is described. The fiber collection tool has a size holdable by the hand of a user, and includes, in its interior, an electroconductive section. Preferably, the fiber collection tool further includes a surface section outside the electroconductive section. In a fiber deposit production method, a user collects, with the fiber collection tool, a fiber spun by the user by performing electrospinning using an electrospinning device having a size holdable by the hand of the user, and thereby produces a film including a deposit of the fiber on a surface of the fiber collection tool. The fiber collection tool, having the deposit formed thereon, is pressed against a surface of an object, and the deposit is transferred onto the surface of the object, to form a film including the fiber deposit on the surface of the object.

Abstract: Provided is a coating having a uniform and strong UV protective effect over the entire skin.
A method for producing a UV protective coating on skin comprising



a step of applying a composition comprising a UV protective agent to the skin, and
a step of electrostatically spraying a composition comprising component (a) and component (b) directly onto the skin to form a coating on the skin, in this order or vice versa:
(a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone,
(b) a polymer having a film-forming ability.
