In order to clarify the morphological characteristics of textured yarn, the individual crimped single filament was separated from the parent textured yarn, and the crimping amplitude and wave-length distribution along a single filament was measured.
The following results were obtained:
(1) The amplitude and wave-length distribution of crimped filament are similar to that observable in the parent textured yarn, and this distribution discloses diagrammatically the morphological characteristics of the crimp caused by the texturing process.
(2) The distribution of amplitude vector along a crimped single filament is identified with the fiber distribution in a cross section of it's parent yarn, and the function of
r, which is the accumlation of each amplitude from the outside to
r along a radius, is correlated with the fiber distribution
f (
r) derived in the previous report
1).
Thus, the fiber distribution
f (
r) was verified also experimentally by the analisis on the wave distribution in a crimped single filament.
