Home • Industry FAQs • The seam is breaking open, how can I prevent this from happening?
  1. Lockstitch machines which use tight tensions have reduced seam elongation and may display premature seam failure because of the seam’s reduced ability to absorb load. The needle thread tension should be set as light as possible whilst still achieving a balanced stitch that does not gape.
  2. The bobbin thread tensions which is set first to ensure a neat seam appearance uses a standard measure for thread tension, this is equal to that of the bobbin case including a full bobbin.
  3. Using better and stronger threads will increase seam strength as will increasing the stitch rating, changing the stitch type or changing the seam used.
