Abstract: A fabric that includes a loop of a yarn including a voltage generating filament. The fabric has a value of X of 1,000 or more, where X=(A+B)×C×D×E, and wherein: A is a loop angle of the loop of the yarn when the fabric is stretched by 10%, B is a connection angle of the loop of the yarn when the fabric is stretched by 10%, C is a number of the loops of the yarn per 1 cm2 of the fabric, D is a force (N) applied per basis weight (g/m2) of the fabric, and E is a surface potential (V) of the yarn.
