Impact of Stitch Type and Stitch Density on Seam Properties

Seam strength, aesthetic look and seam puckering are an important factor in determining the durability of a garment. This is carried out on blended fabric with different structures like plain, twill, satin. Samples were prepared by varying SPI and stitches type. The seam strength was determined by strength tester and carried out on different commercial fabrics for making comparison on seam strength and seam puckering based on the changing SPI values, same needle and two different sewing machine (over lock and plain). The results showed that, the overall seam performance is influenced by different factors. It was concluded from this research that, as SPI was increased, the seam strength was also increased and decreased when SPI was reduced vice-versa as well as SPI increased aesthetic look seam puckering is good.
