摘要： A yarn that includes a fiber that generates a potential on a surface thereof by energy from the outside; and a grounded conductive core material covered with the fiber. The yarn generates a potential of 0.1 V or more on a surface thereof when measured under the following conditions: the yarn is stretched by a predetermined amount in a uniaxial direction; and the potential is measured with an electric force microscope.

摘要： An antibacterial device that includes a substrate, a first electrode on the substrate, a second electrode on the substrate, and a protective layer covering the first electrode and the second electrode and having a first surface opposing of the substrate and a second surface opposite the first surface. Further, the first electrode and the second electrode are arranged such that the protective layer has an electric field strength on the second surface thereof of 150 kV/m or more when a voltage is applied to the first electrode or the second electrode.

摘要： A charging fiber arrangement that includes a pair of adjacent polarization generation fibers that each generate a positive potential or a negative potential on a surface thereof by input of external energy. The pair of adjacent polarization generation fibers are arranged to positively charge a substance passing between the pair of adjacent polarization generation fibers by the positive potential, or negatively charge the substance passing between the pair of adjacent polarization generation fibers by the negative potential.
