ASTM D6828
Standard Test Method for Stiffness of Fabric by Blade/Slot Procedure
The stiffness of fabric relates to its resistance to bending with further processing and use. It measures the fiber and yarn bending capabilities, the cohesion of individual fibers and yarns relative to their displacement and binders or finishes that hold them in place.
What is ASTM D6828?
ASTM D6828 is a standard test method developed by ASTM International for evaluating the stiffness of nonwoven fabrics using the cantilever bending principle. This test method is primarily used to measure the stiffness or flexibility of nonwoven textiles, which are widely used in applications such as medical products, filters, automotive components, and geotextiles. By providing a reliable way to assess how easily a fabric can bend or deform, this standard helps manufacturers and researchers determine the fabric’s suitability for specific applications, where flexibility or rigidity is a critical factor.
The method evaluates fabric stiffness by measuring the force required to bend the material under controlled conditions, providing important insights into its performance. Understanding the stiffness characteristics of nonwoven fabrics is crucial because it affects the fabric’s drapability, handling, comfort, and functional behavior.
