Abstract: The fabric abrasion testing device abrades a fabric sample in a predetermined manner such that the abrading process can be accurately and efficiently observed without halting the abrasion testing. The abrasion testing device includes at least one fabric sample holder for supporting the fabric sample. The abrasion testing device also includes an optically transmissive motion plate that, in a preferred embodiment, securely mounts an abrasion element having a removably engaged abrasive surface for abrading the fabric sample. The operator can therefore look through the motion plate to observe fabric wear during ongoing abrasion tests. The optically transmissive motion plate is operably connected to a motor for moving the motion plate and, in turn, the element mounted therethrough in a predetermined pattern relative to the fabric sample.
