The GB/T 23320-2009 standard describes the method for determining the water-absorption resistance of Spinning & weaving products by flipping absorption method. It details the preparation of the sample, covering the selection, size and condition adjustment of the fabric. It is clear that the test equipment is a specific flipping absorption device, and its Rotation speed, running time and other parameters are specified. In operation, there are detailed specifications for the amount of water added and the test process. Through this standard test, the ability of Spinning & weaving products to resist moisture absorption can be accurately measured. This provides an important basis for the application of Spinning & weaving products in fields such as sportswear and home fabrics, and helps enterprises control the mass of products to meet the needs of fabric water-absorption in different scenarios.
