Abstract:

II THE THICKNESS CONTROL OF YARN IN PRODUCTION BY PLC (M.Sc. Thesis) Yaşar HANÇER GAZİ UNIVERSITY INSTITUTE OF SCIENCE AND TECHNOLOGY January 1998 ABSTRACT Quality of product plays dominant role in textile industry. The quality of fabric is obtained with using yarn with very good quality. By using good quality yarn makes significantly easier to produce fabrics. An important target for yarn producers is to produce good quality yarn. In order to produce good quality yarn, thickness of sliver must be uniform during pruduction processes. In this thesis the thickness of sliver is measured with rotary variable integral transformer (RVTT). Then comparing the measured and reference thicknesses, an error is obtained. Thus according to the error a PLC controls an induction motor drives, which is a pulse- width modulation inverter. This system provides uniform sliver thickness and therefore overcomes the thickness problem of yarn in fabric production.
