Influence of yarn structures; part A: on carpet compressional performance under static and dynamic conditions

Abstract

Three different Indian wools viz. Malpura, Magra and Chokla, significantly different in terms of fibre diameter, proportion of medullated fibres and extent of medullation are selected for this study. Two different mixing approaches i.e. homogeneous and strategic mixing of fibres of different characteristics were used. Three-layered yarn structures were developed to exploit the advantages of the strategic mixing, where wool fibres of different characteristics are positioned in different layers of the yarn as proposed by one of the author of this paper. The compressional performances of handloom carpets made from structurally different yarns were studied using newly developed carpet compression tester measured under static and dynamic conditions.
