This instrument is designed and manufactured in accordance with the national standard ZBW04003-87 "Test Method for Fabric Stiffness-Inclined Cantilever Method". It is suitable for the rigidity and flexibility test of cotton, wool, silk, linen, chemical fiber and other various woven fabrics, knitted fabrics and general non-woven fabrics, coated fabrics and other textiles. It is also suitable for flexible materials such as paper, leather and film. Rigid and flexible test. The bending performance of the fabric is an important physical parameter for us to study the stiffness, drape, softness and other properties of the fabric. This instrument uses two types of bending resistance (also called drape stiffness) and bending stiffness (also called bending stiffness). A mechanical index to express "the ability of the fabric to resist changes in the shape of the bending direction" Instrument Characteristics The infrared beam is used to form an "invisible" detection slope, which replaces the traditional visible slope, realizes non-contact detection, and overcomes the problem that the measurement accuracy is affected by the torsion of the sample being lifted by the slope. At the same time, it is possible to adjust the measurement inclination angle. The automatic detection system overcomes the shortcomings of visual inspection and enhances the anti-interference. The automatic lifting and lowering device of the sample pressing plate ensures the accuracy and consistency of the positioning of the pressing plate and the sample, and improves work efficiency. .
