Standardized test method used to measure the change in size of textile materials after undergoing washing and drying cycles.
In this test, fabric samples are measured before being subjected to controlled washing and drying procedures. After the cycles are completed, the samples are measured again, and the difference in dimensions is calculated. This process helps to evaluate how much the fabric shrinks or expands due to the mechanical and thermal stresses of washing and drying.
The test provides information about the fabric’s ability to retain its original size and shape after exposure to common laundering conditions. It is essential for assessing the stability of textiles and ensuring that they will maintain their intended fit and appearance throughout their intended lifecycle.
