Description
Product Introduction:
It is used to determine the bending length and flexural rigidity of fabrics by the inclined‑plane method. It is suitable for testing the stiffness and flexibility of various woven, knitted, and general nonwoven and coated textiles, including cotton, wool, silk, linen, and synthetic fibers, and is also applicable to flexible materials such as paper, leather, and thin films.
Reference standard:
GB/T 18318.1, BS 3356, ASTM D1388, ISO 9073-7
Working principle:
This instrument employs two mechanical parameters—bending length (also known as suspended stiffness) and flexural rigidity (also known as bending stiffness)—to characterize a fabric’s resistance to changes in its shape when bent. These parameters are collectively referred to as stiffness. A rectangular specimen is placed on a horizontal platform, with its longer edge parallel to the platform’s long edge. The specimen is then advanced along the platform’s longitudinal direction, causing it to extend beyond the platform and bend under its own weight. The free end of the extended portion is supported by a ruler, while the remaining portion of the specimen rests on the platform. When the leading edge of the specimen reaches a slope inclined at 41.5° relative to the horizontal plane, the extension length equals twice the specimen’s bending length, from which the bending length can be calculated.
Scope of supply:
1. One host machine
2. One ruler
