TNG29 吸濕性測(cè)試儀
UMIST Wettability Tester
可檢測(cè)針織、機(jī)織及無(wú)紡布的吸濕、濕潤(rùn)、導(dǎo)濕性能。
測(cè)試時(shí),分別在試樣的四個(gè)方向上互成90度交角安裝接觸式傳感器,傳感器環(huán)的中心有一織物穿刺針頭,針頭上方為電池驅(qū)動(dòng)、可充式的電子移液管,可將一定量的鹽水通過(guò)穿刺針頭而施加于織物上,同時(shí)啟動(dòng)2個(gè)數(shù)字計(jì)時(shí)器,其中當(dāng)傳感器接觸到水溶液時(shí),相應(yīng)的計(jì)時(shí)器停止并顯示出透水性數(shù)據(jù)以評(píng)價(jià)織物成整理劑的潤(rùn)濕效果。
To determine the wettability, wicking or horizontal water permeability of woven, knitted or non-woven fabrics. An adjustable needle pierces the fabric in the centre of 4 contacts space at 90o around a circle. The battery operated, rechargeable electronic pipette is positioned above the needle and a preset quantity of salt water solution is delivered to the fabric, simultaneously starting 2 digital timers, one connected to the "North-South" contacts, and one to the "West-East" contacts. The timers stops when the relevant contacts are reached by the solution, providing data on permeability to evaluate fabrics and finishes.
