AATCC 20

AATCC 20 is a standard test method developed by the American Association of Textile Chemists and Colorists to evaluate laundering durability of textiles. It assesses how well fabrics maintain their appearance, strength, and color after multiple washings. The test involves washing fabric samples under controlled conditions and then examining them for changes such as fading, staining, or fiber degradation. This standard helps manufacturers and consumers understand how various textiles will perform over time, ensuring quality and longevity for apparel and home textiles.
