Abstract
Spectral analysis was used to break up the yarn irregularity into periodic, quasiperiodic, and random components for three different counts, namely 20 tex (30s Ne), 9.9 tex (60s Ne), 5.9 tex (100s Ne), spun at three different levels of drafts and four levels of top and bottom roller eccentricities, and their combinations. The periodic component increases nonlinearly at higher eccentricities and higher drafts and there is also an increase in quasiperiods. This behavior contradicts the commonly accepted theory of linear increase put forward by Foster. The thin and thick places in yarn increase nonlinearly, whereas single thread strength drops rapidly at higher levels of eccentricity and draft. Yam appearance grades deteriorate, particularly with increase in the periodic component. At comparable levels of irregularity, periodic component leads to a diamond barring effect, whereas existence of higher quasiperiods dampens the diamond bars by confounding the periodic component.
