AATCC, based in Research Triangle Park, N.C., has developed a new 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 RA56 Stain Release Committee Task Force, which conducted testing of the replica across six different labs.
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 for 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.
Labs 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.
AATCC would also like to thank the following laboratories that participated in the development of the new Stain Release Replica: SGS Consumer Testing Services, Manufacturing Solutions Center, Hanesbrands Inc., Cintas Corp., Cotton Incorporated and 3M.
