Compressional Behavior of Textile Materials

Abstract

The description of an instrument to measure compressional stress-relaxation characteristics of textile materials at a constant compression, utilizing the sensitive response characteristics of a resistance-wire strain-gage cantilever weighbar, is given. It employs a deflection galvanom eter in conjunction with the strain gages in a D.C. Wheatstone bridge. Compression is applied instantaneously to the specimen and the semilog rate of stress relaxation is determined as a characteristic parameter of the behavior of the textile material.
