The easiest way to determine the carpet is to know how it was produced. Over ninety percent carpets today are made using machines, which are quite similar to sewing machines, but larger in size. These machines operate at high speeds and comprise of hundreds of needles which stitch rows of the yarn with a synthetic fabric. This is also referred to as "primary backing."

During the grouping process, a mechanized “looper” picks up the yarn to make loops, leading to a production of a loop pile carpet. In case of “cut pile” carpets, the loops are sheared of by the blades, resulting in straight yarns which look like cut grass. The combination of cut and intact loops can be noticed in "cut-and-loop" carpet.

The yarns are dyed into different colors if they are not colored previously. This is followed by coating of the “primary backing” with latex adhesives, which is again put through the same process of backing. This second backing is usually of polypropylene. You can notice some carpets in the commercial segments which may have flexible cushions along with the polypropylene backing.

There are other ways of producing broadlooms, as well. Though a negligible percentage, which is less than three percent of the carpets are made on looms which weave the backing and face yarns together. In case of woven carets, you can notice a coat of latex on the bottom side.

Also a few commercially used carpets, usually available in the sizes of 18 by 18 inches, go through the fusion-bonding process, which involves of yarn fibers being injected into an adhesive-coated backing.
