How many combs is a good machine rugs?

The high density of machine-made rugs is one of the things that affect the beauty as much as possible, as well as the strength and durability of the carpet. 1200 shoulder machine carpet is known as one of the best types of machine carpet. Due to its high density, this carpet has very stiff and durable patterns. However, many types of 500- to 700-shoulder carpets have special features such as remarkable softness due to their relatively good density. Therefore, the only factor in choosing a rug is not paying attention to the density and comb of the rug.
