AATCC, the Association of Textile, Apparel & Materials Professionals, announces the availability of L2 lightfastness control fabric. The AATCC Blue Wool Lightfastness Standard is ¨one of a group of dyed wool fabrics distributed by AATCC for use in determining the amount of light exposure of specimens during lightfastness testing.¨
A small amount of the existing L2 lightfastness control fabric, referred to as Lot 8, is still available. Effective immediately, there are no limits on the sale of L2, Lot 8. A new lot of L2 lightfastness control fabric, referred to as Lot 9, has now been produced, analyzed for color and fading characteristics, and approved. L2, Lot 9 will be available for purchase as soon as the supply of Lot 8 is exhausted. AATCC research committee RA50, Lightfastness and Weathering Test Methods, recently approved revisions to AATCC test methods to clarify the use of L2 lightfastness control fabrics for both five AFU and 20 AFU tests.
