  • Publication number: 20220372662
    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 ?/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.

  • Publication number: 20220372658
    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.
