Appearance Evaluation
Standardized testing procedures designed to evaluate the smoothness appearance of fabrics after repeated home laundering guide the finishing mills. The durable press rating aatcc 124 provides a numerical scale from one to five to classify wrinkle resistance. This rating helps garment buyers specify the degree of crease retention and surface smoothness they require for wash-and-wear apparel.
Visual Standard
Evaluation requires a darkened room with controlled overhead lighting to highlight shadows on the fabric surface. Technicians compare the washed specimen with three-dimensional plastic replicas representing the different levels of the durable press rating aatcc 124. Level one indicates severe wrinkling while level five represents a completely flat, smooth appearance.
Production Checkpoint
Mills use this rating to verify that wrinkle-resistant finishes have been properly applied and cured. Achieving a high durable press rating aatcc 124 is necessary for trousers marketed as non-iron. This test protects brand reputations.
Finish Selection
Choosing the correct concentration of resin and catalyst allows mills to meet buyer requirements. If the durable press rating aatcc 124 is too low, the garment will require ironing after laundering, which fails consumer expectations. Conversely, over-processing to achieve a perfect rating can cause the fabric to fail tensile strength tests during inspection.
This balance must be managed.
