Notes:
A new microcomputer-controlled instrument has been developed for making measurements of thermomechanical behavior of polymeric fibers and yarns under conditions relevant to high-speed industrial fiber processing. The instrument can apply extension and/or twist, and rapid heating or cooling in the temperature range 20–300 °C, while tension and torque are measured. Particular novel features are: a temperature control device providing heating or cooling at rates up to 103 K/s; a new form of high-sensitivity torque transducer with resolution of 10−9 Nm; and computer integration of extension, twist, and temperature. The instrument provides an unprecedented degree of flexibility in the design of thermomechanical tests. It is suitable not only as a versatile research tool for material property measurements relevant to processes such as spinning, heat setting, and thermobonding of fibers, but also as a convenient tester for use in quality control on fibers and yarns.
