Seam Failure – Seam Slippage
DESCRIPTION:
Where the yarns in the fabric pull out of the seam from the edge. This often occurs on fabrics constructed of continuous filament yarns that are very smooth and have a slick surface. Also caused by loosely constructed fabrics.
MINIMIZING SEAM FAILURES – SEAM SLIPPAGE:
- Consider changing the seam construction to a French seam construction;
- Increase the seam width or width of bite;
- Optimize the stitches per inch;
- Contact your fabric supplier.Seam Slippage on Rayon Fabric
Skipped Stitches
DESCRIPTION: Where the stitch length is inconsistent, possibly appearing as double the normal stitch length; or where you can see that the threads in the stitch are not properly connected together. Caused by the stitch forming device in the sewing machine missing the thread loop during stitch formation causing a defective stitch. On looper type stitches, this will allow the stitch to unravel causing seam failure.
MINIMIZING SKIPPED STITCHES
- Use a better quality sewing thread. This may include going to a higher performance thread designed to minimize sewing interruptions. (See the Thread Selection Guide and/or Minimizing Thread Breakage & Skipped Stitches);
- Insure proper machine maintenance and sewing machine adjustments;
- Make sure sewing machines are properly maintained and adjusted for the fabric and sewing operation. (See Machine Maintenance Checklist);
- Observe sewing operators for correct material handling techniques. 401 Chainstitch
