Effects of Needle Size and Sewing Thread on Seam Quality of Traditional Fabrics

The role of fabric properties in sewing performance and seam quality is essential, therefore, it is crucial to understand the effect of diferent parameters on traditional fabrics’ sewability properties. This study aimed to evaluate the seam quality of traditional fabrics produced from silk, cotton and linen fibres and their blends in terms of seam strength, seam efficiency and fabric sewability. The samples were sewn using two different sewing needle size (75 Nm and 90 Nm) and sewing thread (100% mercerised cotton and 100% polyester corespun). Based on the obtained results, it can be concluded that sewing thread and fabric type had significant effect on seam strength and seam efficiency. The samples sewn with polyester corespun sewing thread had higher seam strength than other. The sewing needle significantly affected the needle penetration force values and the silk fabric had lowest sewability values both in warp and weft direction.
