What term describes carpet with two distinct backing systems?

Carpet with two distinct backing systems is best described as tufted carpet. This type of carpet is created by inserting loops of yarn into a primary backing fabric. Once the loops are formed, a secondary backing is often applied to provide additional durability and stability. The dual backing system enhances the carpet's strength and helps it maintain its shape during use. This construction method is widely utilized due to its versatility, allowing for a range of textures, patterns, and colors.

Woven carpets, on the other hand, are created in a traditional loom process, producing a single, integrated structure without the need for distinct backing. Needle-punched carpets involve a different manufacturing process that uses barbed needles to entangle fibers into a base material, which does not utilize a separate backing system in the conventional sense. Flat-woven carpets are made without knots and can also lack dual backing, focusing instead on a flat surface. Each of these alternatives represents a unique method of carpet construction but does not feature the same dual backing system characteristic of tufted carpets.
