Similarly, tufting can also involve both cut and looped pile, making it adaptable for various textile applications.

In conclusion, velvet is unique in its limitation to cut pile, which differentiates it from the other textile constructions listed in the question. Understanding this distinction is key for identifying fabric types and their appropriate applications in interior design.
