Empirical Equations and Poisson’s Ratios for Initial Load-Extension Properties of Some Complex Glass and Aramid Technical Weft Knitted Structures

Öz

This work builds on former research carried out concerning load-extension properties of plain knitted glass technical fabrics. In related former research, it was determined that a load-extension or a load-contraction curve could be considered in three stages of extension or contraction. These stages were a) the extension or contraction of the fabric (the first stage), b) the extension of the yarn along with the change of the shape of the sample (the second stage), and, c) the extension or contraction of the fibres (the third stage). In the same works, theoretical analyses were then provided to explain the first stage of extension or contraction, and thus some simple equations between load and extension and between load and contraction together with Poisson’s ratio were obtained. In obtaining the extension of the loop head curve, the equation of extension of a circular ring had been applied. This formulation enabled the emergence of a method that separates the frictional restrains and/or fabric jamming forces from the experimentally obtained quadratic curve fittings for plain knitted fabrics. Building on those former studies, for the present work, similar experimental studies for the first stages of extensions or contractions, were carried out for some more complex technical weft knitted structures that use E-glass and Aramid yarns. The curve fitting equations are obtained and some empirical equations are given, assuming that the same method of separating frictional restrains and/or fabric jamming forces from quadratic curve fittings also applies for complex structures. Extension and contraction rates are also calculated and discussed further. These empirical equations can, of course, be used in related engineering software.
