Abstract
A nonwoven member that includes a plurality of piezoelectric fibers. The nonwoven member is formed into a cloth by intertwining the plurality of piezoelectric fibers. The nonwoven member inhibits the growth of bacteria due to an electric charge generated when an external force is applied to the piezoelectric fibers.
Claims16
An antibacterial material comprising:
- a plurality of piezoelectric bodies arranged so as to generate electric charges when an external force of bending, stretching, and/or heating is applied to the plurality of piezoelectric bodies, the electric charges being sufficient to inhibit growth of bacteria,
- wherein the plurality of piezoelectric bodies include a first yarn constructed to generate a positive electric charge when the external force is applied and a second yarn constructed to generate a negative electric charge when the external force is applied, and
- wherein the antibacterial material does not include conductive yarns that are configured for connection to a detection circuit.
An antibacterial material comprising:
- a mass containing a piezoelectric body, the piezoelectric body generating an electric charge when an external force of bending, stretching, and/or heating is applied to the piezoelectric body, the electric charge being sufficient to inhibit growth of bacteria,
- wherein the piezoelectric body includes a first yarn constructed to generate a positive electric charge when the external force is applied and a second yarn constructed to generate a negative electric charge when the external force is applied, and
- wherein the antibacterial material does not include conductive yarns that are configured for connection to a detection circuit.
