Launching of the new AATCC Stain Release Replica
AATCC, the Association of Textile, Apparel & Materials Professionals (USA) is launching a newly developed digitally printed Stain Release Replica for use with AATCC Test Method (TM) 130, Soil Release: Oily Stain Release Method
The new Stain Release Replica was developed by the Association’s RA6 Stain Release Committee Task Force, which conducted testing of the replica across six different laboratories. The test method is designed to measure the ability of fabrics to release oily stains during home laundering, and it is primarily for use by fabric finishers to evaluate the likely performance of soil release finishes in actual use. If this test method is used as part of a contract between buyer and seller, or in any case, where comparisons between laboratories are being made, the parties should agree to use the same ballast and detergent. In reference solutions, or where standard specifications are involved, 1993 AATCC Standard Reference Detergent should be used.
The study demonstrates that the new replica provides results comparable to those obtained using the previous AATCC Stain Release Replica scale. The overall standard deviation of the new replica was lower than that for the previous replica, suggesting less variability and more discrete determinations. Similarly, the range of individual values for the new replica (minimum to maximum) was narrower than the range from the previous replica, suggesting better precision or less scatter.
The principle is of the test method works as follows: A stain is applied to a test specimen. An amount of the staining substance is force into the fabric by using a specified weight. The stained fabric is then laundered in a prescribed manner and the residual stain rated on a scale from 5 to 1 by comparison with a stain release replica showing a graduated series of stains.
Laboratories using this test method should remember that it is important to replace the stain release replica every 12 months and to store the replica in the dark to prevent fading, as recommended in TM 130.
The following laboratories participated in the development of the new release: SGS Consumer Testing Services, Manufacturing Solutions Centre, Hanesbrands Inc., Cintas Corporation, Cotton Incorporated, and 3M.
