(S. O. R. - Rylander)

The S.O.R. (Standard Oxygen Resistance) method developed by Rylander is a scientific approach used to measure how well certain materials, like clothing or fabrics, resist oxygen transfer. It assesses how breathably or resistant a material is to oxygen flow, which influences comfort and performance in textiles, especially in protective or athletic gear. Essentially, it helps determine if a fabric allows enough air exchange for user comfort or provides a barrier if needed. This standardized method ensures consistent, accurate testing of materials' breathability and resistance, aiding in the development of fabrics that balance protection and comfort.
