A Strain-Gage System for Fiber Testing

A precision research instrument for the measurement of stress-strain-time properties of tex tile materials, which was constructed in the research laboratory of the American Viscose Corpo ration, is described. Classification of this instrument as a research tool rather than as a routine testing instrument allows more flexibility in operating conditions. It is of the constant-rate-of- extension type, for use on all textile materials from single filaments to fabrics. The instrument consists essentially of a constant speed drive, a Statham gage, and a Brown recording potentiometer.
