In the vast world of textile testing, ensuring a fabric's resilience against environmental stressors is paramount. Among these critical assessments, AATCC Test Method 23, ‘Colorfastness to Burnt Gas Fumes,’ stands out as a crucial indicator of how textiles, particularly those containing certain dyes, will withstand exposure to the byproducts of burning natural gas. While not as universally recognized as light-fastness or wash-fastness, this test holds significant weight for textiles intended for environments where gas combustion is prevalent, such as homes with gas appliances, industrial settings, or even vehicles.
