Using geometry equations of Piece’s model and energy method, the structural and mechanical properties of woven fabrics were predicted. The geometrical parameters were obtained from the density of woven abrics, crimp and yam count in order to predict the properties of woven fabrics. The experimentally obtained values of the yarn diameter were observed to be significantly different from those calculated by Peirce’s equation that can be used to predict the diameter from the yarn count. This observation required modification of the Peirce’s equation. The structure of woven fabrics was obtained by utilizing the yam diameter estimated by the modified Peirce's equation. The structural parameters based upon the modified Peirce's equation were very close to the experhentally obtained values. The mechanical behavior was also predicted from the structural parameters by applying the energy method.
The load-extension relation was calculated by substituting the initial modulus and bending rigidity into the equation describing the structure of fabrics. In case of plain fabrics, the load-extension relations for cotton, wool and polyester fabric systems as a function of relaxation state of fabrics were in good accord with experimental data. Furthemnore, some fundamental s t r u c u parameters for Z/Z mat, 2/1 twill, 3.4 twill, satin and rib fabrics were also calculated by using both the Peirce‘s equation and the modified one and the calculated parameters were compared with experimental data. The load-extension curves obtained by calculation showed similar tendencie3 observed in plain fabric systems.
