Checking the fusing result
Bond Strength
The bond strength can be measured easily with a spring
balance. The indications are in kp/50mm or N/50mm. A general
bond strength value cannot be given as this depends on the
kind of interlining or fabric. Therefore the interlining
manufacturers indicate the required bond strength per interlining
Appearance of adhesion test
After fusing, fabric and interlining are pulled apart. The adhesion
test gives a special indication: With a good bond the coating of
the interlining should have been transferred 50% or more to the
fabric. If this is not the case, the bond is not sufficient.
