AATCC 88c:2006 pdf download.Retention of Creases in Fabrics after Repeated Home Laundering
1. Purpose and Scope
1.1 This test method is designed to evaluate the retention of pressed-in creases in fabrics after repeated home laundering,
1.2 Any washable fabric may be evalu- ated for crease retention using this method,
1.3 Fabrics of any construction, such as woven, knit and nonwoven, may be eval- uated according to this method.
1.4 Techniques for creasing are not outlined, since the purpose is to evaluate fabrics as they will be supplied from manufacturing or as ready for use. Fur- thermore, creasing techniques would be controlled by fabric properties.
2. Principle
2.1 Creased fabric specimens are sub- jected to standard home laundering prac- tices. A choice is provided of hand or ma- chine washing, altermative machine wash cycles and temperatures and alternative drying procedures. Evaluation is per- formed using a standard lighting and viewing area by rating the appearance of specimens in comparison with appropri- ate reference standards.
3. Terminology
3.1 ballast, n.- -in procedhures for pro- cessing or testing of lextiles, material that is used to bring the total weight or vol- ume of the textiles to an amount specified in the procedure.
3.2 crease retention, n.- in fabrics, the visual impression of an inserted crcase quantified by comparison with a set of reference standards.
3.3 durable press, adj.- having the ability to retain substantially the initial shape, flat scams, pressed-in creases and unwrinkled appearance during use and after laundering or drycleaning.
3.4 laundering, n.- of texrile materi- als, a process intended to remove soils and/or stains by treatment (washing) with an aqueous detergent solution and nor- mally including rinsing, extracting and drying.
4. Safety Precautions
NOTE: These safety precautions are for information purposes only. The pre- cautions are ancillary to the testing proce- dures and are not intended to be all inclu- sive. It is the user's responsibility to use safe and proper techniques in handling materials in this test method. Manufac- turers MUST be consulted for specific details such as material safety data sheets and other manufacturer's recommenda- tions. All OSHA standards and rules must also be consulted and followed.
