Fabric Elongation and Extension Properties
topic
Elongation testing measures percentage extension at specified load or at break under standardised tensile conditions, distinguishing elastic elongation recoverable upon load removal from plastic deformation; bi-axial extension tests simulate body movement stresses in stretch fabrics and elastic composites.
Role
Essential for activewear, compression hosiery, and technical stretch fabrics where controlled extensibility and recovery determine comfort, fit retention, and functional performance over repeated wear cycles.
