Abstract
A single fabric testing apparatus is capable of measuring mechanical and thermal characteristics of a specimen previously carried out in separate testing apparatuses. The single apparatus is provided with a plurality of mechanical and temperature sensors and a heatable top plate. In use, a ram moves the top plate vertically downwards to press a fabric specimen against a bottom plate. The plate is surrounded by a fixed upstanding peripheral skirt against which an outer periphery of the specimen is bent to enable shearing and bending characteristics to be measured. The bottom plate is biased upwards by a spring which is compressed until the top plate is arrested by a fixed frame member. Further downward movement of the ram enables compressibility of the specimen to be determined. A rotatable section of the top plate can be turned by a stepping motor to determine the surface friction characteristics of the specimen.
