What is‘sewability'?

Mar. 20 , 2019

‘Sewability' of thread is a term used to describe a sewing thread’s performance. A thread with good sewability is uniform in diameter with a good surface finish. Longitudinal uniformity of thread contributes to uniform strength and reduced friction, as it passes through the stitch forming mechanisms. It also minimises thread breakages and the associated costs incurred from rethreading machines, repairing stitches and producing inferior quality products.  

Sewability parameters 

The parameters that define the superior sewability of thread are:

        *No breakages in high-speed sewing

        *Consistent stitch formation

        *No skipped stitches

        *Evenness, to prevent changes in tension during sewing

        *A high level of abrasion resistance

        *Sufficient surface smoothness, to pass easily through the machine guides
