Model: C0051

The tuft retention property is one important factor in the useful life of a tufted or traditional carpet.  Carpets which are badly constructed or poorly backed may lose complete tufts in some situations, for example on stairs.  In loop pile carpets, a good bind is necessary to prevent long runner loops formed.

The IDM Tuft Withdrawal Tensometer 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 instrument is normally used on small samples of carpet in the laboratory, but the balance may be detached and used in selected positions on large pieces or on carpets already laid.

Test Method:
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.

The standard instrument is supplied with a digital force gauge
registering up to 10kg, for testing carpets pile binding force.
