What is defined as the separation of the primary and secondary backing on tufted carpets?

The separation of the primary and secondary backing on tufted carpets is referred to as delamination. This occurs when the layers of the carpet begin to come apart, which can happen due to various factors including the age of the carpet, environmental conditions, or the use of improper cleaning methods. Delamination can lead to a significant reduction in the carpet's durability and aesthetic appeal, as it may result in visible bulging or wrinkling.

Fraying refers to the unraveling of the fibers, typically around the edges, which does not involve the backings of the carpet. Pilling involves the formation of small balls of fibers on the surface of the carpet, while soiling refers to the accumulation of dirt and stains on the carpet's surface, none of which relate to the separation of the backing. Understanding delamination is crucial for carpet care professionals, as they need to recognize the signs early to either recommend proper maintenance or, if necessary, replacement.
