Abstract
A yarn containing a potential-generating filament. The yarn is constructed such that a positive or negative surface electrical potential is generated by applying an external force to the yarn in an axial direction of the yarn, and constructed such that a controlled surface electrical potential is generated by a maintenance or release of the external force.
Claims14
A yarn comprising:
- an electric field-forming filament comprising polylactic acid having a crystallinity of 15 to 55%;
- and
- a dielectric material containing a surfactant having a cationic functional group or an anionic functional group over an entire circumference of the electric field forming filament,
- wherein the yarn is constructed such that a positive or negative surface electrical potential is generated by applying an external force to the yarn in an axial direction of the yarn, and constructed such that a controlled surface electrical potential is generated by a maintenance or release of the external force.
