Differences in the Tensile Properties and Failure Mechanism of PP/PE Core/Sheath Bicomponent and PP Spunbond Fabrics in Uniaxial Conditions
Source abstract
Abstract
The tensile failure mechanism in thermally point-bonded bicomponent spunbonds is elucidated based on core/sheath PP/PE filaments. These fabrics exhibit high extension and low tensile strength. In contrast to 100% PP spunbonds, where there is limited bond deformation prior to failure of the fabric, the bond points in PP/PE bicomponent spunbonds undergo large deformations during uniaxial extension before fabric breakage occurs. Failure occurs mainly within the bond points rather than around their perimeter.
