Abstract:

The aim of this research was to investigate the resilience properties of textile systems fused with different interlinings by applying the method of pendulum impact loading. For the investigations, four worsted outer fabrics and four interlinings were chosen. For testing, a pendulum impact device was used, the operation of which is based on cyclical strikes of the spherical indentor upon the specimen, taking into account the resilience and deformability of the material. It was defined that resilience properties could be characterised not only by the values of impact bn and angles rebound αn but also by the duration of vibration periods Tn. It was defined that the decay of pendulum impact bn and rebound angles αn in the period of t = 20 s can be described by power function y = a + bxc with a high accuracy (R2 = 0.995 - 0.999). For the rebound process, better resilience of fabrics and their fused systems is characterized by higher values of power function coefficients a and b and lower values of its coefficient c. For the impact process, lower deformability of the samples tested is characterised by lower values of power function coefficients a and b, but with a more intensive decrease in deformability – by higher values of coefficient c. The degree of the fused system’s deformability directly depends upon the thickness and mass per unit area of the interlinings used, i.e. less deformable and more stable systems were obtained with thicker interlinings, the mass per unit area of which was higher.
