NWSP 90.3 Stiffness (Handle-O-Meter)

Standard:

NWSP

Method:

NWSP 90.3

Title:

Handle-O-Meter Stiffness of Nonwoven Fabrics

Scope

The NWSP 90.3 Stiffness test method┬ácovers the evaluation of the stiffness or “hand” of nonwovens. The quality of “hand” is considered to be the combination of resistance due to the surface friction and the flexural rigidity of a sheet material.

All of the instruments operate on the principle of deforming the nonwoven through a restricted opening. It is a flexibility test in which the force required to deform a loop of nonwoven is measured.

The SI values are regarded as the official standard system of measurement for this standard test method. If other systems of measurement are used in place of SI units (including inch-pound) their values must be reported independently. Systems of measurement must not be combined in any way, but shall be regarded and reported separately

Principle

The nonwoven to be tested is deformed through a restricted opening by using a blade to force a specimen through a slot with parallel sides.
