GB/T 4802.2-2008 Focus Spinning & Weaving Fabric Pilling Performance Determination, using Modified Martindale Method. The standard first introduces the principle and uses a specific friction method to simulate the daily friction scene of fabrics. Detail the required equipment, including parameters such as Martindale Wear resistance instrument. Describe the sample preparation steps, specify the friction time, pressure and other test conditions, and the method for evaluating the pilling grade. Provide a unified specification for the accurate detection of the pilling performance of Spinning & weaving products, help control the product mass, and meet the market's evaluation needs for fabric durability.
