What is it called when the secondary backing separates from the primary backing of the carpet?

The phenomenon where the secondary backing separates from the primary backing of a carpet is known as delamination. This process can occur due to a variety of factors including water damage, excessive heat, or inadequate adhesive used during manufacturing. Over time, the bond between the backings can weaken, leading to a separation that not only affects the carpet's appearance but also its functionality and longevity.

Delamination is particularly concerning because it can prevent the carpet from lying flat, leading to buckling or wrinkling. This condition can compromise the carpet's overall durability and could eventually require significant repairs or even replacement. Other terms listed, such as separation, peeling, or fraying, describe different issues or damages that may occur in carpets but do not specifically refer to the distinct problem of the backing layers coming apart. Understanding this terminology is crucial for effective carpet maintenance and addressing potential issues before they escalate.
