Application
To determine fabric stiffness using the ASTM circular
bend test method. This test method is generally
applicable to all types of fabrics, including woven,
knitted and nonwovens, of any fiber content.
A plunger of 25.4mm (1 in) diameter pushes the
fabric through a 38mm (1.5 in) diameter orifice for a
distance of 57mm (2.25in) in 1.7 seconds and and the
maximum force is recorded.

Feature

• Provided with 500 N digital force gauge with peak-hold facility, accuracy: 0.1N
• N, kgf, lbf can be switched.
• Can record and calculate 10 groups test data.
