Hidden cost of thread

Although thread is not an expensive component, it has a significant impact on output and sewing productivity. The wrong choice of thread hampers production and can result in problems such as thread breakage, sewing stoppages, slower machine speeds, and higher repair rates after denim wash programs.

The hidden cost of choosing the wrong thread

  • Thread breakage
  • Skipped stitches
  • Sewing stoppages
  • Needle breakage
  • Slower machine speeds
  • Higher repair rates
  • Poorer quality garments

When a thread breaks, rethreading takes 7 seconds in a lockstitch machine, and up to 2 minutes in an overlock or cover seam machine. These interruptions in the production line could cost you 30 to 45 minutes of productive time each day.

When choosing the right thread for denim production, qualities including their impact on machine performance, seam strength and durability are crucial. Corespun threads, like Coats Epic and Dual Duty, have been developed for modern day factories. Due to their construction and specially formulated lubrication, these high tenacity and versatile threads are ideal for denim production. They deliver excellent sewing performance in the most demanding applications such as automatic pocket setting, and provide outstanding abrasion resistance.

Key considerations when selecting sewing threads for denim production

  • Impact on machine speed and performance
  • Seam strength to keep the seam secure
  • Seam stretch to provide the elongation required
  • Durability and toughness to withstand the washdown processes
  • Qualities to create the desired appearance, including colour fastness or fade, and thickness for stich definition

Take advantage of the benefits that Coats sewing threads can bring to your denim production process – fewer repairs and higher optimum running speeds.

How much is denim washing costing you?

Are you washing your dollars down the drain? Using the wrong thread can result in post-washing repair rates as high as 40%. With Coats’ proven denim solutions you can banish costly after wash repairs and focus on creating high performance iconic denim pieces which will last a lifetime.

Denim washing processes are many and varied. Often the objective is to distress the garment to achieve a desired appearance and to soften an otherwise harsh fabric. However, denim washing can have a devastating effect on sewing threads and therefore seams if care is not taken in their selection and application.

Coats’ range of sewing threads have been designed specifically to withstand the rigours of denim washing and to create distinctive denim pieces through contrast colours and other decorative applications.

Common denim washing challenges


  • Undesired colour changing after bleach washes
  • Seam weakening and broken stitches after pumice stone washing
  • Seam abrasion and poor seam appearance after enzyme washing
