tuft bind

Tuft bind is a capacity for an individual carpet tuft to resist being pulled from the carpet.  Alternatively stated, tuft bind is a measurement of how strongly bonded an individual carpet tuft is attached to the carpet.  Tuft bind is measured in inch-pound units.

High tuft bind reduces the risk of edge ravel, sprouts, yarn pulls, and zippering.  Tuft bind is nearly exclusively determined by the quality of the backing system.  Generally, traditional broadloom carpets have lower tuft bind than broadloom carpets with special moisture or cushion backings.  Modular carpet will normally have a higher tuft bind than broadloom carpet.

Tested by ASTM D1335 "Standard Test Method for Tuft Bind of Pile Yarn Floor Coverings."
