Influence of Layer Orientation upon Textile Systems Tensile Properties. Part 1. Investigation of Tensile Strain and Resilience

Abstract

Bilayer textile systems composed of outer fabric and interlining were investigated in this work. The aim was to investigate tensile properties such as tensile strain ε and resilience RT using KES-F (Kawabata Evaluation System for Fabrics) automatic tensile/shear system at garment wearing level loads. Tests were performed with four woven outer fabrics and two interlinings (warp knitted and non-woven). Three types of fused textile systems were prepared by changing orientation of fusible interlinings, i.e. parallel, bias and perpendicular to outer fabric warp direction. Tensile properties of fused systems were investigated in longitudinal and transverse directions (in respect to outer fabrics warp direction) and on the basis of obtained results recommendations were given to achieve the desirable mechanical reaction of fused textile system. Influence of layers’ orientation upon textile systems mechanical behaviour, i.e. tensile strain ε and resilience RT at low tensile loads is significant for fused systems which are tensioned in transverse direction and insignificant for systems tensioned in longitudinal direction in respect to outer fabrics’ warp direction.
