As the needles and yarn are pushed through a backing fabric and pulled out, loops or tufts are formed and held in place by a primary backing. An adhesive coating, usually a latex compound, is applied to anchor the tufts permanently. In some carpet constructions, a secondary backing is adhered to the carpet to provide additional strength, stability and body. Because it is a rapid, economical method, tufting is the most common carpet construction method. Surface and backing yarns are intertwined to make a single construction.
Knitted carpet is similar to woven in that pile and backing yarns are interlocked in one operation.
A core of fiber sheet and layers of loose fibers on each side are interlocked by a machine punching thousands of needles through them. Fibers Different natural and manmade fibers are used to construct carpet and rugs. Each fiber has distinct properties of its own. For the manmade fibers, manufacturers usually call them by their own trade names. In addition to the differences of fiber content, the look and feel of your carpet or rug will also be determined by its texture or pattern.
