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 electric charge generation yarn meets requirements (a) to (e) mentioned below simultaneously and suppresses proliferation of bacteria by electric charge generated upon deformation of the yarn: (a) a main component of the yarn is polylactic acid; (b) the yarn is twisted; (c) the yarn has a double torque of 50 T/50 cm or less; (d) the yarn has a single fiber fineness of 0.05 to 5 dtex; and (e) the number of filaments in the yarn is 10 to 400.
