Which type of carpet backing provides dimensional stability by stitching yarns to a primary backing?

Tufted carpet is characterized by its construction method, where yarns are stitched or tufted into a primary backing material through the use of specialized machines. This technique not only allows for a variety of textures and patterns but also enhances the dimensional stability of the carpet. The yarns are held firmly in place, which minimizes the potential for distortion or shifting over time, making tufted carpets durable and resilient.

In contrast, woven carpets involve interlacing yarns to create the finished product, which results in a different structure that does not rely on the same tufting process for stability. Needle-punched carpets are made by entangling fibers with barbed needles, creating a non-woven fabric that lacks the stitched aspect found in tufted carpets. Cut-pile carpets refer specifically to a styling where the loops of yarns are cut to create a plush surface but do not specifically address the method of dimensional stability provided by the backing. Thus, tufted carpet stands out for its method of construction and the stability it offers through the stitching of yarns to a primary backing.
