Rugs: Woven, Knotted, and Tufted

When looking for a new rug, sooner or later you’ll come across the many different types of rug manufacturing. Whether the new rug should be tufted, woven, or hand-knotted is often not just a matter of taste but also of price. The types of rug manufacturing are as varied as the rugs themselves, and each method has its merits. But how exactly do these carpets differ, and what are the advantages and disadvantages of each manufacturing method? The following sections provide a comprehensive overview of the different types of carpet manufacturing and answer the questions above. This way, your next carpet purchase is guaranteed to be a success!

Weaving is one of the oldest handicraft techniques used to produce textiles. It is no coincidence that the term “fabric” is often used interchangeably with “woven material.” According to archaeological research, this technique is believed to have been known as early as the Neolithic period. Almost anything can be woven: blankets, clothing materials, wallpaper, and, of course, carpets. Carpets can be produced using this method either by machine or by hand. All types of weaving involve at least two sets of threads. The warp threads form a kind of framework through which the weft thread is pulled back and forth from one side to the other. The denser the resulting fabric, the more durable and long-lasting it is.

With handwoven rugs, there are virtually endless variations in colors and patterns. However, the production process is much more labor-intensive and can take anywhere from months to years, which is reflected in the price. Wool and hemp are the preferred materials for this method.

Fully automatic looms, which process yarn from a thousand spools simultaneously, have replaced hand weaving in many areas. This allows carpets to be produced more quickly and at a lower cost. Unfortunately, only up to ten colors can be used at a time. In addition, the carpets are manufactured in fixed widths. Therefore, the desired sizes are subsequently cut to size and finished with appropriate edges.

Carpet weaving is a very ancient art that was likely developed by nomads in Central Asia. There are two maintypes of knots commonly used: the symmetrical knot and the asymmetrical knot. On a loom, warp threads—which serve as the base—are knotted together with individual wool threads. Various tools are used for this, such as knotting hooks, as well as different types of scissors and knives. At your favorite carpet store, you’ll find two fundamentally different types of knotted carpets. In addition to hand-knotted pieces, there are also those produced by machine. 

Hand-knotting is a time-consuming process that used to be performed almost exclusively by women. Once completed, the rug is cut off the loom and undergoes a final finishing process. This includes trimming and making the fringes. In addition, the long sides are edged.Wool, cotton, or silk is used for knotting. Hand-knotted rugs come from various countries and regions. They often differ in their patterns and the colors used. In all cases, the work is very labor-intensive, and this is naturally reflected in the price. 

Tufting is not only done commercially with machines (such as those used for carpeting), but also by hand. But what exactly is involved in this process, and what does “tufting” actually mean?

In addition to hand-knotted rugs, there are also machine-knotted ones. Machine-knotted rugs are, of course, produced much faster than hand-knotted ones. The manufacturing process allows only fixed widths, which are later cut to the appropriate sizes. It is possible to create a wide variety of patterns, but you must limit yourself to 8 to 10 colors. Sometimes, after cutting the carpet to size and sewing the edges, fringes are also added. These are sewn onto the narrow sides, whereas in hand-knotting, the fringes are formed from the warp threads. Materials used in machine-knotting include wool and cotton, as well as synthetic and artificial fibers.

Using a tufting gun, the pile yarn is tufted from the back of a backing fabric made of 100% cotton in such a way that any desired structure, cut pile, or loop pile can be created on the front side of the fabric. Any desired size and shape can be tufted, and the material, shape, color, structure, and design can all be customized. Hand-tufted carpets are manufactured in Germany, Central Europe, India, China, Thailand, Singapore, and Hong Kong. After the pile yarns are tufted, they are coated with a latex compound on the back of the carpet, thereby anchoring them in place. The carpets are then dried in the sun or in drying rooms. The carpet is then fitted with a cotton backing, the edges are bound, the pile is sheared smooth, and the pattern is highlighted by a relief cut. These steps are performed entirely by hand. The material—such as wool, polyacrylic, polyester, viscose, etc.—as well as the pile weight per square meter are the main factors determining differences in quality and price.

Machine tufting of carpets is based on the principle of a sewing machine. Instead of a yarn gun, the thread is inserted into the fabric using needles. Before the needles are withdrawn, the inserted yarn is held in place by grippers. This creates loops on the surface of the carpet. If the loops are cut, the result is a velour carpet. As with hand-tufted carpets, the backing of a machine-tufted carpet is fully glued and fitted with a secondary backing. Machine-tufted carpets are, of course, less expensive than hand-tufted carpets. But what really sets machine tufting apart is the ability to produce looped carpets.
