AATCC Test Method 88C-2018t, Crease Retention in Fabrics after Home Laundering

Technicallyequivalent to ISO 7769.
This test method and its accompanying three-dimensional crease replica set were developed for evaluation of woven fabrics with a durable-press finish. It is common industry practice to use the method
and replicas for evaluation of other textile materials although some specimens may have different appearance characteristics due to different fabric constructions.
Standard laundering procedures remain consistent to allow valid comparison of results. Standard procedures represent, but may not exactly replicate, current consumer practices, which vary over time
and among households. Alternate laundering procedures and machine parameters may be found in Laboratory Procedure (LP) 1, Home Laundering: Machine Washing (see 12.3).
1. Purpose and Scope
1.1 This test method is intended to determine the retention of pressed-in creases in fabrics after being subjected to home laundering procedures. Several washing and drying procedures provide standard parameters to represent common home care options.
1.2 Creases in any washable fabric (woven, knitted or nonwoven) may be evaluated for retention using this method.
1.3 Techniques for creasing are not outlined, since the purpose is to evaluate creases as they will be supplied from manufacturing or as ready for use. Furthermore, creasing techniques would be controlled by fabric properties.
