How to improve seam performance against slippage in garments?
- Most slippage occurs in the seams that run parallel to the warp.
- Slippage will more likely to occur in fabrics that have filament yarns, low counts and unbalanced weave.
- Seam slippage may also be affected by stitch type and size, tension, seam type and size, thread used for sewing and excessive use of fabric lubricant.
- A tighter stitch will reduce seam slippage as stitches grip fabric.
- Using higher stitch per inch (SPI), lapped seam and double row of stitches will increase the grip, hence reduces seam slippage
- By increasing seam margin (allowance) as the higher number of stitches in between seam and cut edge create a resisting force to slippage.
- Sewing the seam with lining fabric or tape will help to reduce slippage. Seams cut along with warp line are more prone to slippage than those cut on the bias.
