Abstract
The description of an instrument to measure the compressional characteristics of textile materials at a constant rate of compression and recovery, utilizing the high speed and sensitive response characteristics of a resistance-wire strain gage cantilever load cell, is given. It employs a high-speed, sensitive, rectilinear, electronic recorder in conjunction with the strain gages in an amplified and rectified A.C. Wheatstone bridge. Reversal of the direction of travel of the deforming foot is obtained by use of manual- or limit-switch controlled magnetic clutches. A wide range of load scales and traveling foot speeds may be obtained. Response curves are given for a variety of textile materials to indicate their behavior characteristics and illustrate the many ways in which the instrument may be employed.
