Light, heat and moisture act synergistically on textile materials causing changes in color and mechanical properties. To address these changes systematically, the first lightfastness instrument was introduced 100 years ago.

Today, several ISO, AATCC, and company standards are available for testing colorfastness to light of textiles for various applications. Specific requirements, terminology, reference materials, and evaluation scales make those methods unique in the weathering world. Understanding textile testing standards is key to make the right testing decisions.

In this Online Seminar you learn about:

  • The effect of light, heat and moisture on textiles
  • ISO, AATCC, and company test methods
  • Blue Wool, Red Wool, Grey Scale
  • Outdoor and Perspiration to Light testing
