AATCC Test Method 124-2014 details a procedure for evaluating the smoothness appearance of flat fabric specimens after multiple cycles of home laundering. Designed for any washable fabric, including woven, knit, and nonwoven constructions, the method simulates consumer washing and drying conditions. Fabric specimens are subjected to standardized home laundering practices, with choices for hand or machine washing, various cycles, temperatures, and drying procedures (tumble, line, drip, screen dry). Following laundering, specimens are visually rated against a set of three-dimensional smoothness appearance replicas in a controlled lighting and viewing area. Trained observers assign a numerical grade from 1 (poor appearance) to 5 (very smooth), quantifying the fabric’s planarity and freedom from wrinkles. The method emphasizes the importance of consistent conditions and provides guidance on reporting results, precision, and bias, serving as a critical tool for assessing textile performance and quality retention after domestic care.
