garment defects and causes

1. SEAM SLIPPAGE
Seam slippage is the condition where a seam sewn
in the fabric opens under load. Some of this gap may
close on removal of the load but some of it may be a
permanent deformation.

2. Causes of seam slippage
• Loosely woven fabric {Fabric with low number
of wefts and warps}
• Not using enough stitches per inch
• poor stitch balance
• too narrow seam margin

3. Seam Grin
• When two pieces of fabric are pulled at right
angles to the seam, a gap is revealed between
the two pieces of the fabric revealing the
thread in the gap.
