Model: C0051-A

The IDM Tuft Withdrawal Fixtures are used alongside a tensile machine to measures the force required to withdraw a single tuft or loop of pile from a carpet – that is, the binding force between carpet pile and backing. 

The carpet sample is held down by a steel plate, and a pair of surgical forceps is clamped to one end of the tuft to be tested, or a hook threaded through one loop. 

The forceps or hook are linked to a digital force gauge, which is raised at a steady rate by a small electronic motor.  Tension on the tuft or loop is thus increased and the digital force gauge indicates the maximum force needed to withdraw it.

Applications:
• Textile floor covering which has a tuft (cut) loop pile yarn structure
• Woven: individual loops
• Woven: individual cut tufts
