Effect of Thermosetting Process Parameters on Extensibility and Dimensional Stability of Viscose/Elastan Knitted Fabrics

In this study, the extensibility, permanent elongation and shrinkage properties of the viscose knitted fabrics including covered elastane before and after the thermosetting process were investigated. In this context, the effects of thermosetting parameters such as temperature, speed and overfeeding were revealed in industrial scale. The results showed that the process speed had not a significant effect on fabric properties; on the other hand, the temperature and the overfeeding values significantly affected the extensibility and dimensional stability of the fabrics. From these results, it was determined that by increasing the temperature and the overfeeding, it is possible to provide a good stretchability as well as high dimensional stability
