Effect of seam angle on seam puckering in lightweight woven fabrics

摘要: Displacement puckering is the major cause of seam puckering, while sewing lightweight woven fabrics. In this paper, effect angle (0°–90° to weft) on has been studied for cotton and polyester fabrics at different stitch lengths. Puckering estimated by measuring a difference between thickness seamed unseamed It observed that decreases then increases as weft increases. Seam lowest 30° 69 g/m2 fabric; 45° 88 g/m2 fabrics, depending upon warp yarns covered in yarn linear densities, which can be represented effective relative cover. angle, when cover highest.
