GB/T 29778-2013 is a standard for the evaluation of potential phenolic yellowing in Spinning & weaving products. It specifies the method for evaluating the possibility of yellowing in Spinning & weaving products due to phenolic substances. The standard specifies the equipment and reagents required for the test, and specifies the operation process of simulating the phenolic yellowing environment in detail, including key conditions such as temperature, Humidity, contact time and concentration of phenolic substances. The degree of potential phenolic yellowing in Spinning & weaving products is assessed by observing and analyzing the color change of Spinning & weaving products after the test. This standard provides an important basis for the Spinning & weaving industry to prevent and control phenolic yellowing problems in advance and ensure product mass and Appearance Stability.
