Typical hygroscopic fibers are cotton, wool, rayon, silk, flax, etc. Moisture content isparticularly critical in the case of dynamometric properties, i.e. yarn tenacity, elongation, and work-tobreak,but yarn evenness, imperfections, and defect levels are also affected. As a result, conditioningand testing must be carried out under constant standard atmospheric conditions. The standardtemperate atmosphere for textile testing according to ISO 139 involves a temperature of 20±2°C(68±4°F) and 65±4% relative humidity. The standard alternative atmospheres according to ISO 139shall have a temperature of 23±2°C (73.4±4°F) of and a relative humidity of of 50±4%). Thealternative atmosphere may be used only if the parties involved agree on its use. Prior to testing, thesamples must be conditioned under constant standard atmospheric conditions until in moistureequilibrium with the surrounding air. To attain the moisture equilibrium, a conditioning time of at least24 hours is required, 48 hours is preferred. For samples with a high moisture content (thermallyconditioned yarns), conditioning time should be at least 48 hours.USTER ® STATISTICS 10 (36)
