Research on surface geometry of woven fabrics of different structure

Abstract

The geometric structure of surface of textile materials is of significant functional, operational and aesthetic importance. Generally, the geometric structure of the surface of materials consists of three main elements: shape, waviness and roughness [1,2]. Parameters characterizing a quality of fabrics surface, i.e. surface topography are strongly related to the fabrics’ structure, raw material composition and a way of finishing. The aim of presented work was to analyse the parameters characterizing the geometric structure of the surface of cotton woven fabrics with different weaves. Totally, 12 fabric variants were the objects of the investigations. They were woven fabrics of 6 weaves and 2 kinds of weft yarn. Surface topography measurements were made by means of the MicroSpy® Profile profilometer by FRT the art of metrology™ [3]. Using the Mark III software cooperating with the profilometer, the basic parameters characterizing the geometric structure of the fabrics’ surface were determined according to standard [4]. Results showed that the fabrics differ between each other in the aspect of the majority of parameters characterizing the surface geometry. Statistical analysis confirmed that weave and linear density of weft yarn significantly influence the surface properties of the investigated fabrics.
