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.
