A laboratory measure of the force needed to pull a single tuft out of a carpet's backing, usually expressed in pounds or newtons. It is one of the most revealing specs on a carpet datasheet: low tuft bind is what turns a snag into a run, especially in loop pile where one pulled loop can unzip a whole row. Good latexing or thermal bonding raises it dramatically.
A specialized tufting technique where the needles create an X-pattern in the carpet backing rather than straight rows. This method increases tuft bind strength and creates a more stable, durable carpet construction that resists pile distortion in high-traffic areas.
