Fabric Stiffness Tester - TNG1098

The TNG1098 is designed to assess the stiffness properties of fabrics through a bending test. The instrument operates by placing the specimen on a measuring plane and allowing one end to gradually lift off the support, enabling the fabric to bend under gravity. The bending length is measured when the fabric contacts an inclined plane, and calculations determine the bending stiffness. The TNG1098 complies with ISO 9073-7 and supports optional standards such as ASTM D1388 Method A, ISO 4604, and BS 3356. It is suitable for woven, layered, napped, knitted, and pile fabrics. The device features a tilt angle of 41.5º and an accuracy of 0.1º. The pressure plate is equipped with a scale for real-time observation of movement, ensuring precise measurement without specimen deformation. The dimensions of the instrument are 350 mm in length, 100 mm in width, and 200 mm in height. The TNG1098 provides a reliable method for evaluating fabric stiffness in a controlled and repeatable manner.

Fabric Stiffness Tester is practical equipment to determine fabric’s bending height, flexural rigidity, and bending modulus. This tester provides a quick and intuitive way to know the stiffness performance of all kinds of fabrics like woven, layered, napped, knitted, pile, etc. Besides, this blog will give you detailed information about fabric stiffness and its measurement.

The Principle of Bending Stiffness Test

Place the specimen on the measuring plane of the instrument, and then slowly move the sample forward. This is done to allow one end of the specimen to gradually break away from the plane support and hang in the air. Under the influence of gravity, one end of the specimen is bent downwards. When bent to the inclined plane, measure the extension length and calculate the bending length and bending stiffness of the fabric according to the formula.

By pressing the platen against the specimen by its own weight, the platen follows the standard very closely, so there is no specimen deformation.

The pressure plate is equipped with a scale for real-time observation of the travel.

Test Procedure 1 Take the samples from a representative section of the fabric and should not contain any folds or creases. Cut four samples of meridional and zonal by parallel or trapezoidal method, and the sample size was 200mm*25mm. 2 Adjust the instrument level. Place the sample face up on the platform, one end aligned with the front of the platform. Put up the pressure plate and make the indicator line coincide with the "zero" line of the ruler. 3 Pushing forward the pressure plate at a certain speed and driving the specimen to move forward until the specimen reaches contact with the inclined plane. Record the scale reading. 4 Lift the pressure plate and test the specimen back up again. 5 Calculate the arithmetic mean value by the values measured on the positive and negative sides as a reading of the extension length of the sample.
