Carpet Tuft Extraction Tension Tester
Application
The Carpet Tuft Extraction Tension Tester is designed to evaluate the retention strength of tufts in tufted carpets and traditional woven carpets. This tester helps determine how well carpet tufts are anchored in the backing, which is a critical parameter for durability and wear performance. It is widely used in carpet manufacturing, quality control, and research laboratories.
Standards
BS 5229: 1975 (1996) – Methods for determining the tuft withdrawal strength of carpets.
ISO 4919: 1978 – Textiles — Methods for determination of tuft withdrawal force of pile fabrics.

FAQ
What is tuft extraction testing?
Tuft extraction testing measures the force required to pull a tuft from the carpet backing, indicating the strength of tuft anchorage.
What types of carpets can be tested?
Both tufted carpets and traditional woven carpets can be tested.
How is the sample held during testing?
The carpet is fixed in a steel template, and individual tufts are grasped with surgical forceps or hooked with a metal hook.
Can the tester measure high-strength carpets?
Yes, standard models measure up to 5 kg, and optional models can measure up to 10 kg for stronger carpets.
Is the force applied consistently?
Yes, the electric motor provides a steady and controlled increase in pulling force, ensuring reproducible results.
What is the typical power requirement?
The instrument consumes 20 W and typically operates on 220V, 50Hz power supply.
Why is tuft retention important?
Tuft retention is critical for carpet longevity and resistance to wear; poor retention can lead to shedding and early deterioration.
