Seam Performance Evaluation of Plain Fabric Using Different Dyes in Garments Dyeing

The seam performance, such as seam strength, seam slippage, and seam efficiency is an important factor of a garment. The durability of a garment depends on the longevity of a seam. Now a day’s fabric is dyed in the form of garments. So, it should be known about the seam properties how can it influenced after dyeing. The seam strength and seam elongation are the important factor for some purposes of end use such as domestic, decorative, functional, and protective, etc. So this study compares the longevity of seam before and after dyeing with alternative four dyes (direct dye, reactive dye, vat dye and pigment color) applied on sewn 100% cotton woven plain fabric which sewn by white colored polyester core spun thread (40/2 Tex). Dyed and undyed garment panels (specimen) are prepared along to the both in warp and weft direction for testing. In both warp and weft direction five samples of each group were taken for testing. The testing procedure was followed according to the ASTM method; D1683-04 and D5034. Seam performance evaluated in three different stages as grey panel, pretreated panel and dyed panel. In this study Universal strength tester was used for evaluation seam strength and seam slippage. The study was performed by taken 6.0 mm seam slippage to measure the breaking load. It was observed breaking load of the undyed garment panel were show higher strength than the dyed garments without seam opening. Here also discussed in details that, seam strength, seam slippage and seam efficiency not only influenced sewing thread, fabric construction, needle size, sewing machine condition etc. also dyestuffs can influence seam properties.
