Abstract
Abstract An apparatus and related method for testing and recording distention characteristics of stretchable fabrics or garments under simulated body stresses and more particularly knitted Tshirts and briefs. A pair of fabric carrying members are moved by a variable force to simulate body stresses on the T-shirt or brief. Distention over the range of the variable force is recorded automatically.
