The impact of stitch density and seam class on the moisture management properties of seams was investigated in this study. A lapped seam (Class 2) using a Flat Lock Stitch class ASTM 607 and a super imposed seam (Class 1) using an Overlock Stitch Class ASTM 514 were constructed with four different stitch densities – SPI 10, SPI 14, SPI 18 and SPI 22, and the moisture management properties of seamed fabric in terms of the spreading speed, area of spreading, absorption time, wetting time, one-way transport index and overall moisture management capability (OMMC) on the seam line were investigated. It was observed from the results that the seams made with low stitch density show better moisture management capability, and the lapped seam exhibits better moisture management capability when com-pared to the superimposed seam. © 2020, Institute of Biopolymers and Chemical Fibres.
