Abstract
It is difficult to determine the surface contour of fabrics, because fabrics are soft, delicate and flexible. This article aims to determine the surface contour on textile fabrics by a light reflection method using a goniophotometer and two stylus methods provided with stylus instrument trially manufactured. It also aims to investigate the relation between test results of surface contour obtained by these methods and those by a visual assessment. A contour of a fabric surface is traced by a light or stylus which is attached to the tip of strain gauge transducer or core of displacement transducer.
The result obtained by these methods has shown that the surface contour of fabrics can quantitatively be estimated from the average height of amplitude (Hx or H) in refiecting or tracing contour curves. The high correlation are obtained between results of these methods and those of a visual pared comparison.
