to the textile field for the first time for tracing the yarn hairiness
spectrogram from the output signals of Shirley hairiness meter, using 11 yarn
samples widely differing in hairiness characteristics. The amplitude and
wavelength of the hairiness periodicities would be useful for analyzing the
causes of hairiness formation from the point of view of producing quality
yarns.</span
