Types of Constructions
Hand-Knotted
The most expensive & oldest form of rug construction, Hand knotted rugs are made on a specially designed loom and are knotted by hand. The making of hand knotted rugs is a very ancient art that deserves a lot of admiration! The size of the loom depends on the size of the rug and the weaving is done from the bottom to the top. The rug weaver inserts the “knots” into the foundation of the rug and they are tied by hand, this makes up the “pile” of the rug. You can see these “knots” by turning over the rug.
Hand-Tufted / Hand-Hooked
These are the most popular constructions used today and are more reasonably priced than hand-knot. Hand tufted rugs are a type of rug that is considered handmade or hand-crafted. Tufted rugs are made using a modified hand held drill gun that inserts the pile into a cloth foundation which creates a loop pile. If the loop pile is sheared, it then becomes a cut pile. The loop pile rug, if not sheared, is called a Hand-Hooked rug. These rugs have a handmade look but they cost much less because using the gun speeds up the process dramatically. A latex coating is then applied to the back of the rug to hold the “tufts” in place. A canvas type fabric is then applied over the latex coating to finish the back of the rug.
Flatweaves
Flatweaves are another category of handmade rugs. These rugs are hand-woven in a flat weave pattern and there is no pile. There is virtually no height to the rug. Soumak, Dhurrie, Kilim and Braided are all types of flatweave rugs. With a flatweave, you will definitely want to put a rug pad under it to help it stay in place and provide a little more cushion to the rug. Natural fibers, wool, and cotton, all make good materials for flatweave rugs. Playa, Natura, Bahama, and Horizon (Indoor/Outdoor) are good examples of KAS’ flat weave collections.
Power-Loomed / Machine-Woven
Machine-made rugs are made by large machines called power looms. A power loom is electrically automated and controlled by computers. Machine-made rugs can be made quickly and are manufactured with materials including wool and synthetic fibers such as polypropylene, nylon, polyester, acrylic and art silk. Machine-made rugs lack the flexibility of a handmade rug in that pre-determined patterns and colors are used and others cannot be added in process. There are two types of looms used to create three different categories of Oriental reproductions: Wilton, Cross-woven Wilton, and Axminster. Each of these can be designed to achieve various pile heights, densities, finishes and qualities.
Shags
Shag rugs are one of the more popular trends today. They are fun and easy to decorate with. Shag rugs can be handmade or machine made using a variety of constructions. The distinctive feature of this quality is the longer length of the fibers. The fibers may be fine and silky or thick and soft.
Types of Fibers used in Rugs
NATURAL FIBERS
Wool
Wool is a versatile fiber that dyes easily to create a limitless range of colors. Because of the natural scales on a wool fiber surface, light is diffused and provides a soft appearance with less shine. Wool is naturally resilient and elastic, thereby enabling it to retain a dense pile through the weight of furniture, traffic and other uses for area rugs. Wool is extremely durable and maintains a good appearance for longer periods. There are different grades of wool with New Zealand wool noted as one of the finest.
Cotton
Cotton is available in many colors, provides softness and fits well into casual homes.
BLENDED YARNS
Any of the above natural and synthetic fibers may be blended. Synthetic fibers such as olefin and nylon are petroleum products, while rayon – a man-made alternative to silk – is synthesized from cellulose found in trees. Animal-derived natural fibers include wool spun from sheep, goats, llama and alpaca. Plants produce natural fibers such as sea grass, jute, flax and cotton.
SYNTHETIC FIBERS
Nylon
Nylon is manufactured in an unlimited variety of colors, resists soil and is easily cleaned. The resilient nature of nylon withstands the weight of furniture and heavy traffic. Nylon is very strong, abrasion-resistant and elastic. While nylon can simulate the look and feel of wool, its lustrous quality will create a relatively shiny appearance in area rugs.
Olefin / Polypropylene
Olefin is the predominant machine-woven synthetic fiber. Olefin has a soft wool-like feel, but resists wear and stains while being colorfast, strong and affordable.
Polyester
Polyester provides softness when constructed into thick, cut pile textures for area rugs and durability in furniture fabrics.
Acrylic
Acrylic can be blended with other fibers to provide the look of wool at a lower cost.
