What factors are considered when selecting thread?

11 October 2023

Remember:Thread only makes up a small percent of the cost of the sewn product, but shares 50% of the responsibility of the seam.

Selecting the proper thread for your product is achieved by first determining the end-use requirements of your sewn products including: seam strength requirements, stitch & seam design, optimum stitch length, and the normal life of the product. Other factors that are considered include the type of material being sewn, the type of sewing machines being used, conditions under which the product must perform, and cost effectiveness.

Physical characteristics that vary from fiber type and thread construction include:

  • tenacity

  • averange strength

  • elongation at break

  • twist construction

  • ply security

  • stitch appearance

  • colorfastness
