Abstract

Measurement and monitoring of product characteristics during of production is very important to achieve improvement in product qualities. According to increased rate of machinery speed this issue becomes more important, especially in case of yarn texturing because of high demand of textured textiles. In this investigation, new methods introduced for determination of crimp indices in FALSE TWIST and KNIT DE KNIT TEXTURED YARNs. In FALSE TWIST TEXTURED YARNs the box counting and distance fractal dimension used in addition to crimp percentage to achieve good correlation with CRIMP CONTRACTION. The filament's structure at KNIT DE KNIT TEXTURED YARNs were very regular and flat, so in this case the crimp percentage can explain the total CRIMP CONTRACTION of this type of yarn. Finally, utilization of fast Fourier Transforms on images of this type of yarns, successfully predicts the frequency and length of crimp waves.
