On the Apparatus Used for Longitudinal Vibration Experiments in Textile Fibers over the Range of Frequency from Subsonic to Supersonic

Abstract

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 experi ments with the apparatus, some findings on Nylon-6 fiber are presented briefly. From these findings it appears that the so-called " Relaxation spectrum " of 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.
