UMISTWettabilityTester可检测针织、机织及无纺布的吸湿、湿润、导湿性能。测试时，分别在试样的四个方向上互成90度交角安装接触式传感器，传感器环的中心有一织物穿刺针头，针头上方为电池驱动、可充式的电子移液管，可将一定量的盐水通过穿刺针头而施加于织物上，同时启动2个数字计时器，其中当传感器接触到水溶液时，相应的计时器停止并显示出透水性数据以评价织物成整理剂的润湿效果。Todeterminethewettability,wickingorhorizontalwaterpermeabilityofwoven,knittedornon-wovenfabrics.Anadjustableneedlepiercesthefabricinthecentreof4contactsspaceat90oaroundacircle.Thebatteryoperated,rechargeableelectronicpipetteispositionedabovetheneedleandapresetquantityofsaltwatersolutionisdeliveredtothefabric,simultaneouslystarting2digitaltimers,oneconnectedtothe"North-South"contacts,andonetothe"West-East"contacts.Thetimersstopswhentherelevantcontactsarereachedbythesolution,providingdataonpermeabilitytoevaluatefabricsandfinishes.标准Standa***BS4554)
