The Carpet Peel & Tuft Tester allows testing the quality of carpet flooring. It determines the tuft withdrawal force. Poor quality carpets lose complete tufts in most situations. For example, their application on stairs. Especially for loop pile carpets, bining is necessary. This is because it prevents formation of long runner loops. Tuft retention property is also an important factor of a tuft or traditional carpet.
The Carpet Peel & Tuft tester is a motorized instrument measures the force to peel backing material from carpet. And also, to withdraw a single tuft, or loop of pile.This test method covers the measurement of force required to pull or break a tuft from a pile floor covering sample
Carpet Tuft Testing
Tuft retention property is also an 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.
Carpet Peel Test
The backing of the carpet piece is fastened to the instrument, by sample grips. One grip is secured to the base of the motorised test stand and the other is secured to the digital force gauge. The force is raised at a steady rate and the digital gauge indicates the tension force as the sample backing is peeled from the carpet.
Tuft & Loop Withdrawal Test
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 the digital force gauge, which is raised at a steady rate. (The average test time for the achievement of the maximum withdrawal force of the tufts and loops should be between 5s and 10s). Tension on the tuft or loop is increased and the digital force gauge indicates the maximum force needed to withdraw the tuft or loop.
Carpet peel and Tuft 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.
