Physical properties of sewing threads and their performance in relation to seam construction

Abstract

Polyester spun sewing thread is commonly used in high-speed sewing machines in the garment manufacturing process. Recently core spun sewing threads produced with polyester filament core and polyester sheath fibres have been introduced to the local garment industry .Poly/ploy core spun thread is believed to give superior quality performance inseams. The spun polyester and core spun sewing threads are having different structures and as such, their properties will be significantly different. The behavior of these threads in different types of seams would provide an insight to the performance of core spun (poly/poly) and 100% polyester sewing threads. The results of this research project show that the core spun would give superior performance in seams and the thread consumption is less when the core spun thread is used.
