The aim of the research was to investigate the effect of interlinings orientation upon fused textile systems resilience and to define the relation between fused textile systems pendulum impact behaviour (biaxial deformation) and mechanical properties determined by KES-F system (uniaxial deformation). Outer fabric and two interlinings with polymer adhesive layer: non-woven with longitudinal threads P1 and warp knitted TR1 were investigated. Fused textile systems were formed by changing the orientation of interlinings at: 0 (system PAR), 90 (system PER) and 45 (system B) degrees in respect to outer fabric warp direction. For the investigations of fused textile systems resilience properties computerized pendulum impact device was applied. Tensile properties were determined using KES-F system. The investigations of the effect of interlinings orientation upon fused textile systems resilience have shown that this property is the highest for B systems. Resilience of fused textile PAR systems is the lowest because tensile strength of interlinings in longitudinal direction defined by KES-F system is the highest. Meantime for fused PER systems it is no difference which interlining can be chosen for fusing because resilience properties of both systems are almost similar. The investigations of bilayed fused textile systems have revealed that the parameters of biaxial behaviour obtained in impact loading are related with the anisotropy of tensile strain EMT and tensile resilience RT determined by uniaxial KES-F testing, i.e. the increase of rebound angle α1 and decrease of impact angle β1 are closely related with the decrease of EMT and RT anisotropy.
