ActiveTextiles--Tests for colour fastness--Detection and assessment of photochromism
纺织品 色牢度试验 光致变色的检验和评定
Application Summary AI generated
This standard specifies a method for detecting and assessing photochromism in textiles, which is the reversible color change that occurs when a fabric is exposed to light. It is applied in the textile industry to evaluate the color stability of dyed or printed fabrics under light exposure, particularly for products like apparel, upholstery, and automotive interior textiles. The testing context involves exposing specimens to a specified light source and comparing the color change to a grey scale to determine the degree of photochromism.
