Fabric, and fiber product

A fiber product comprising:

• a first fabric;
• and
• a second fabric,
• wherein the first fabric comprises a loop of a yarn containing a potential generating filament,
• wherein the first fabric has a value of X of 1,000 or more, where:
• X=(A+B)×C×D×E
• 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 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, and
• wherein the second fabric has a stretchability, and
• wherein
• the loop angle is larger than 0° and smaller than 90°,
• the connection angle is 0° to 75°,
• the number of the loops of the yarn per 1 cm2 of the fabric is 100 to 1500,
• the force (N) applied per basis weight (g/m2) of the fabric is 0.01 to 1.2, and
• the surface potential (V) of the yarn is 0.1 V or more, and
• an antibacterial activity value is 2.2 or more.
