Study on the Spirality and Shrinkage of Weft Knitted Fabric: An Impact of Tumble Drying and Line drying

Abstract

Spirality and shrinkage are the most common problems for knitted fabric due to their asymmetrical loop formatton. Spirality is a dimensional distortion in circular knitted fabrics and has an obvious influence on the aesthetic and functional performance. Shrinkage is the process in which a fabric becomes smaller than its original size while washing and drying. This study explicitly determined the theoretically approach of the causes and remedies of spirality and shrinkage and the main dffirence between tumble and line drying. The tumble drying was more responsible for shrinkage contrary to the line drying. Among the samples the full feeder lycra single jersey shows the best result in shrinkage and spirality and double pique shows the worst result due lo more tuck loop in its structure. Finally, this study illustrated that line drying was the best for using the garments with assured quality and dimensional stability.
