Material Analysis & Testing

Concordia has a dedicated quality control lab and regularly tests all incoming raw yarns, work in process, and finished goods according to the statistical standards called out by ANSI/ASQC Standard Z1.4-2008.

The tests performed vary according to customer requirements but could include:

  • Twist checks.
  • Denier checks.
  • Extraction tests to determine the amount of finish on a yarn.
  • Dry and wet residual shrinkage tests.
  • Bulk testing of textured yarns.
  • Tensile testing for strength, tenacity, elongation, modulus, and other related factors.
  • Friction testing.
  • Electric resistance/conductivity testing.
  • Visual inspection for a wide range of potential defects including broken filaments, poor package formation, and dropped plies.
