WIRA Thickness Gauge for bulky Nonwovens greater than 20 mm

Bulky nonwovens with a thickness of greater than 20 mm should be tested on this apparatus. The specimen is placed on a base plate and covered by a glass plate, the pressure exerted on the sample is 0.02 kPa. The measuring arm is lowered until the pointer touches the surfaceof the glass plate. The thickness is read from the digital display

WIRA Bending LengthTester

The WIRA Bending Length tester is used to determine the Bending length of a nonwoven fabric, and from this the flexural rigidity can be calculated. The apparatus is manufactured from clear Perspex. Test pieces are cut from the fabric measuring 250 x 25 mm. Each test piece is tested from both ends and with both sides uppermost (4 tests in total). The strip is placed on the platform with the leading edge of the fabric in line with the front edge of the platform. The steel ruler is placed on top of the fabric. The ruler and fabric are moved forwards together until the fabric extends down in line with the engraved markings. The distance moved is then read from the ruler
