Benefits of technology

The patent text describes a yarn that can generate a potential and has an antibacterial effect. The yarn can also charge other substances by generating a potential. The technical effect of this invention is the ability of the yarn to kill bacteria and to provide a potential for charging other materials.

Problems solved by technology

However, Patent Literature 1 does not disclose how much potential is generated on a surface of the charge generating fiber.
If the generated potential is too low, a desired effect may not be produced.

Embodiment Construction

[0017]Hereinafter, an embodiment of the present invention will be described. FIG. 1A is a partially exploded view illustrating a configuration of a yarn 1, and FIG. 1B is a cross-sectional view taken along a line A-A of FIG. 1A.

[0018]The yarn 1 is a multifilament yarn formed by twisting a plurality of fibers 10. The fiber 10 is a fiber having a circular cross-section. The yarn 1 is a left-spiraled yarn (hereinafter, referred to as a Z yarn) in which the fibers 10 are leftward spiraled and twisted.

[0019]The fiber 10 is made of, for example, a piezoelectric polymer. The fiber 10 is manufactured by, for example, a method of extruding and molding the piezoelectric polymer into the fiber. Alternatively, the fiber 10 is manufactured by a method in which the piezoelectric polymer is melt-spun to be formed into the fiber (examples thereof include a spinning / stretching method in which a spinning step and a stretching step are separately performed, a straight stretching method in which the sp...

Abstract

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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation of International application No. PCT / JP2020 / 020041, filed May 21, 2020, which claims priority to Japanese Patent Application No. 2019-099434, filed May 28, 2019, the entire contents of each of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a yarn and a fabric that generate a charge.BACKGROUND OF THE INVENTION[0003]For example, Patent Literature 1 discloses a yarn and a fabric including a charge generating fiber that generates a charge by energy imparted from the outside. The yarn and the fabric of Patent Literature 1 exhibit an antibacterial effect by the generated charge.[0004]Patent Literature 1: Japanese Patent Unexamined Publication No. 2018-090950 bulletinSUMMARY OF THE INVENTION[0005]However, Patent Literature 1 does not disclose how much potential is generated on a surface of the charge generating fiber. If the generated potential is ...
