Prediction of Compression of Knitted Orthopaedic Supports by Inlay-Yarn Properties

Abstract

The aim of this study was to find out the possibility to predict the compression properties of orthopaedic knits by inlay-yarn properties. For this purpose, six groups of elastic double covered threads with different raw material were investigated. It was established that in area of low elongation, the covering threads practically don't have significant influence on tensile force values. Also results demonstrate that by increasing the number of tested threads, the elongation value has a higher impact on tensile force. The influence of linear density of elastic PU core on tensile force increases by increasing elongation value of threads. When influence of inlay-yarn linear density and number of threads on tensile force is determined it is possible to predict influence of inlay-yarn properties on compression properties of knitted orthopaedic supports.
