The tufting process creates clusters of blades known as tufts. The tuft bind—referred to in German as tear-out strength or tuft withdrawal force—indicates in Newtons how firmly these clusters are anchored in the backing fabric. Measurement is carried out according to EN ISO 4919.
Factors it depends on
- Quality and quantity of the back coating
- Structure of the backing
- Aging due to UV light and weathering
Why it is important
Low tuft bind results in blades coming loose—especially during sports, dogs playing, or brushing. Minimum values for sports surfaces are defined in the testing specifications. For garden lawns, look for brand-name products with verifiable manufacturer specifications.
