Which type of carpet is manufactured by entangling fibers and applying an adhesive as a backing?

Needle punch carpet is indeed the correct choice as it is produced by a unique manufacturing process that involves the entanglement of fibers through a needle punching method. This technique uses barbed needles to mechanically interlock the fibers, resulting in a durable and dense carpet structure. After the fibers are interlocked, an adhesive is applied as a backing, further securing the fibers in place and creating a stable product that can withstand various levels of foot traffic.

In the context of other types of carpets, woven carpet is created by interlacing yarns on a loom, which results in a more complex and sturdy design, but does not involve the needle punching method. Tufted carpet is made by sewing or "tufting" strands of yarn into a primary backing and typically involves a different process compared to needle punch. Finally, modular carpet, often referred to as carpet tiles, can be manufactured using tufted or woven methods, but these also do not utilize the needle punch technique specifically. Thus, needle punch carpet stands out for its unique production method that combines fiber entanglement and adhesive backing, which results in a distinct finished product suitable for various applications.
