Abstract

The paper presents a method based on a special equipment and a projector microscope connected with an image processing system for measuring the diameter and the twist angle to study the cross-section contraction and the changes in the surface twist during tensile testing or twisting the yarns. As experimental studies polyester rayon yarn as well as ring-spun and rotor-spun yarns were tested and analysed. It is demonstrated how to use the results in modelling yarns.

Keywords:

contraction of yarn; yarn diameter; twist angle; image processing
