1.1 These accelerated laundering tests are to evaluate the colorfastness to laun- dering of textiles which are expected to withstand frequent laundering. The fabric color loss and surface changes resulting from detergent solution and abrasive ac- tion of five typical hand or home launder- ings, with or without chlorine, are roughly approximated by one 45 min test (see 9.2-9.6). However, the staining ef- fect produced by five typical hand or home launderings cannot always be pre- dicted by the 45 min test. Staining is a function of the ratio of colored to undyed fabrics, fiber content of fabrics in the wash load and other end-use conditions which are not always predictable.
1.2 When this test method was origi- nally developed, various options of this method were intended to evaluate the color change and staining by five home or commercial launderings, on an accel- erated basis. Throughout the years, com- mercial laundering procedures have changed and commercial cleaning today involves many different types of pro- cesses, dependent on the type of product being cleaned that cannot be duplicated by one accelerated laboratory procedure. In 2005, all references to commercial laundering were removed as it is not known if these procedures accurately rep- licate typical commercial laundering pro- cesses used today.
3.1 colorfastness, n.—the resistance of a material to change in any of its color characteristics, to transfer of its color- ant(s) to adjacent materials or both, as a result of the exposure of the material to any environment that might be encoun- tered during the processing, testing, stor- age or use of the material.
3.2 laundering, n.— of textile mate- rials and/or stains by treatment (washing) with , a process intended to remove soils an aqueous detergent solution and nor- mally including subsequent rinsing, ex- tracting and drying.AATCC 61 pdf download.
