Abstract
The present disclosure describes natural antimicrobial carpet pads that are flexible and resilient sheets of predominantly natural plant fibers and/or animal fibers. These fibers have been subjected to a nonwoven needling process to form a mat. An antimicrobial material is intermixed with the plant and animal fibers. The antimicrobial material may also serve as a bonding agent for the fibers.
