Özet

The main aim of the study is to investigate how the yarn cross-section changes along the yarn path in woven fabrics and how these changes relate to the yarn and fabric parameters such as yarn linear density, twist factor, warp and weft cover factors. Based on the elliptical cross-section model, yarn flattening coefficients were calculated along the yarn path. A general equation of change in yarn flattening coefficient was developed in the form of e = a(1 +) (2cosN(x))(a) and the equation coefficients were analysed to find out the effects of the control factors. Twist factor was found to be the primary factor that had effects on a(1) and a(2), whereas the yarn linear density caused the highest change in N value.
