Gelbo Flex Tester with Particle Counter G0005

Gelbo Flex Tester with Particle Counter G0005

Gelbo Flex Tester with Particle Counter G0005 is used to measure the amount of loose fibres (lint) shed from non-woven materials in a 30 second time period of flexing. Non-woven textile materials must have a low tendency to lint.

G0005 is a fast and accurate instrument for determining the linting of non-woven materials. Measuring of loose fibres can also be carried out to other materials like tissues. The sample is subjected to repetitive twisting and compression cycles, air is withdrawn from the testing chamber and particles in the air stream are counted and classified with the laser particle counter.

Gelbo Flex Tester with Particle Counter consists of two 82.8mm diameter mandrels, one fixed and the other attached to a moveable arm to perform the flexing action. The moveable mandrel twists and compresses the sample at 60 cycles/min of 180° rotation over 120mm of stroke. Flexing Chamber measuring 300 x 300 x 300 mm which has removable panels for easy cleaning with built in Isokinetic intake probe (air collector), and HEPA filter to reduce the incoming dust & lint.

Particle Counter counts and sorts the particles in real time with relevance to sizing from 0.3 to 25.0μm or 0.5 to 25.0μm. The counter will simultaneously monitor up to 6 environmental sensors such as temperature, humidity, air velocity or differential pressure. These are recorded whilst measuring particles. It has a flow rate of 1CFM (28.3 LPM) and is able to store up to 3,000 data sets including particle and environmental data, plus location time etc. It also prints reports on a built in thermal printer.
