Apparatus available for measuring the dynamic mechanical properties of textile fibers over a range of frequency from subsonic to supersonic are described in the following article. As an example of the results of experiments with the apparatus, some findings on Nylon-6 fiber are presented briefly. From these findings it appears that the so-called “Relaxation spectrum” of Nylon-6 belongs to the category of the so-called “Box type distribution”, which is a special feature of textile fibers, at least, over a range of relaxation time corresponding to the range of frequency measured.
