Investigation of seam puckering in woman's blouse

In this study, mechanical properties of the fabrics were investigated in order to fi nd the cause for seam puckering problem in armhole and neckline area of woman’s blouse. The same model of woman’s blouse was produced from two types of fabrics with diff erent raw material content: 100% silk and 100 % polyester. The obtained results show that both fabrics have a low shear rigidity, indicating that fabrics extension in bias direction is high. The fabrics extension in bias direction has infl uence on seam puckering in armhole and neckline area of the blouse because there is sewing in bias direction except sewing in warp and weft directions.
