A chemical application to carpet fibers that reduces static electricity buildup, particularly important in commercial environments with electronic equipment.
A rug about 100 years old or older, the point at which an old rug is called antique rather than vintage or semi-antique. Age is a price factor of its own, since a 200-year-old rug costs more than an otherwise equal 100-year-old one, and it works alongside artistry, rarity (for example the output of a workshop that no longer exists) and condition. Very old rugs have often been repaired at some point, which shows most clearly from the back, so condition calls for close inspection.
Famous Persian carpets originally from the Ardabil region in northwestern Iran. The most renowned example is displayed in the Victoria and Albert Museum in London, dating from the 16th century. Known for their exceptional craftsmanship, medallion design, and historical significance in Islamic art.
The carpet-weaving enterprise of the charitable organization that runs the Imam Reza shrine in Mashhad, Iran. It began as a small operation weaving chiefly for the shrine and, in the early 1980s (about four years after the Iranian revolution), grew into a large-scale producer of Mashhad rugs, reportedly over 6,000 square meters (about 65,000 square feet) a year with more than 500 artisans. It is known for special dyes, described as natural vegetable dyes, that give deep reds and blues. Rugs bearing its signature were often destined for shrines or commissioned as gifts.
A flat-woven decorative carpet originally produced in France, characterized by floral designs, medallions, and architectural elements in pastel colors. Traditional Aubussons were handwoven tapestries used by French nobility.
A type of machine-made carpet with a cut pile surface, known for intricate patterns and durability. Named after the town of Axminster in England where it was first produced.
The layer on the underside of a tufted or machine-made carpet that provides stability and structure. Primary backing holds the carpet fibers, while secondary backing adds strength and dimensional stability. The back of these carpets is typically stiff and plastic-like because it is synthetic (polypropylene, polyester or nylon), and it does not reveal the front pattern. A hand-knotted rug has no separate backing, canvas or latex layer: its back is the woven foundation, usually cotton, with the knots in plain view, softer to the touch and showing the front design.
Yarn extruded as one endless strand and then texturized, as opposed to staple yarn spun from short lengths. The distinction answers a question every new carpet owner asks: staple constructions shed loose fibers for weeks after installation, while BCF carpets barely shed at all, because there are no short fiber ends to work loose. Most modern synthetic carpet is BCF.
A style of carpet characterized by loops of the same height, often flecked with color. Originally referred to handmade North African carpets but now commonly refers to loop pile carpets with a distinctive speckled appearance.
A floral motif of rose bouquets found in Bijar rugs and borrowed from French carpets. It goes back to the nineteenth century, when a revival of rug weaving in Iran took its inspiration from Europe, and it is one of several outside influences on Bijar design, alongside the rugs of Isfahan and Kashan and Russian and Caucasian designs.
A strip of fabric sewn along the edge of a carpet or rug to prevent fraying and give a finished look, as on area rugs and stair runners. A hand-knotted rug is normally finished differently: the weaver wraps the weft several times around the outermost warp to form the overcast, or selvage, usually a rounded, corded edge (sometimes flat, or in a contrasting wool) whose regional style helps experts tell where the rug was made.
Carpet patterns and textures inspired by nature, designed to bring elements of the natural world into interior spaces. Part of the broader biophilic design movement that aims to increase occupant connectivity to the natural environment.
Carpet manufactured in wide widths (typically 12 or 15 feet) on a broad loom. Refers to wall-to-wall carpeting as opposed to carpet tiles or area rugs.
Various techniques for cleaning carpets, including hot water extraction (steam cleaning), dry compound cleaning, bonnet cleaning, and encapsulation, each suited to particular carpet types, soiling levels, and drying times. Hand-knotted rugs need gentler care: side-to-side vacuuming with a canister vacuum whose beater bar is off, sparing the fringes; an occasional light wipe with diluted, bleach-free dish foam on white cotton towels, worked in sections along the pile so it dries within about an hour; and a professional wash every 5 to 10 years, every 3 to 5 in heavy traffic, and before storing a rug for a year or more.
Square sections of carpet (typically 18"×18" or 24"×24") that can be installed individually and replaced as needed. Popular in commercial settings for their flexibility, ease of installation, and reduced waste during replacement.
A carpet with a design created by cutting pile to different heights, creating a three-dimensional, sculptured effect. Often used to add visual interest and texture to solid-colored carpets.
A globally recognized measure of safer, more sustainable products made for the circular economy. For carpets, it evaluates material health, product circularity, clean air and climate protection, water and soil stewardship, and social fairness.
The towering rack of yarn packages that feeds a tufting machine — often holding well over a thousand cones at once, one for every needle across the machine's width. Pattern and color changes begin here: rethreading a creel can take a full shift, which is why machine-made carpet is economical in long runs of one design and expensive in short custom batches.
A certification program by the Carpet and Rug Institute that identifies carpets, adhesives, and cushions with very low VOC (Volatile Organic Compound) emissions for better indoor air quality.
A measure of how tightly a carpet is packed. In machine-made carpet it describes the fibers in the pile and is calculated by multiplying the face weight by 36 and dividing by the pile height; higher density generally indicates better durability and performance. In hand-knotted rugs it means knot density (KPSI, knots per square inch), counted on the back and averaged over several areas (150 KPSI is about 23 knots per cm²). Like image resolution, higher density allows finer curves and sharper designs, usually with a lower-trimmed pile and more labor, but it is not the sole measure of quality: bold geometric village rugs are made at low to medium density.
A structural technique in which alternate warp threads are pulled to a second, lower level inside the rug, so the knots pack into two planes instead of one. This is the hidden engineering behind many very finely knotted carpets: it nearly doubles the achievable knot density and produces a stiff, heavy handle. Running your fingers across the back of a rug and feeling ribbed, offset knot nodes is a classic connoisseur's test for warp depression.
A quality check on how evenly a rug's design mirrors itself, relevant to the many Persian and Oriental designs meant to be symmetrical: the medallion should sit at the true center, and corner pieces and other motifs should match each other and be spaced correctly. Handwork is never perfectly symmetrical, and exact repetition points to machine making; tribal and village weavers working from memory vary most, while workshop weavers following a drawn plan come closest to exactness. Noticeable lopsidedness lowers a rug's harmony and is one of the variables that affect its price.
A carpet installation method where adhesive is applied directly to the subfloor and the carpet is laid on top. Common in commercial settings and for carpet tiles, providing a secure installation without the need for padding.
A carpet installation method where the padding is glued to the subfloor, and then the carpet is glued to the padding. Provides extra stability and is often used in high-traffic commercial areas.
Carpets manufactured with sustainable materials, low environmental impact production methods, and recyclable components. May include carpets made from recycled materials, natural fibers, or those produced with reduced water and energy consumption.
A type of flooring that combines multiple layers of different materials for improved stability and performance. In the context of carpet, may refer to carpet tiles with engineered backing systems designed for specific performance characteristics.
A transparent, objective report that communicates the environmental performance and impact of a carpet throughout its lifecycle. EPDs are based on international standards and life cycle assessment methodology.
A carpet deliberately treated after weaving to look worn and antique. The finish typically involves washing (often stone washing, sometimes chemical treatment), occasionally strong sunlight, and cutting the pile short, which softens the colors and leaves a thin, low pile while keeping the durability of a new rug; many new Oushak-, Kazak- and Peshawar-style rugs are finished this way. Treated color can be told from genuine age: it looks bleached and shows a sharp band of color inside the fiber, whereas natural fading is gentle and even from tip to base, so a worn look alone does not prove a rug is old.
Traditional carpets woven by the Esari tribe of Turkmenistan, characterized by their distinctive deep red background and geometric gul (medallion) patterns. These rugs typically feature a primary elephant foot gul design with secondary motifs arranged in orderly rows, and are known for their fine weave and rich cultural symbolism.
The modern method behind most woven Wilton carpet: two carpets are woven simultaneously as a sandwich, connected by shared pile yarns, then a traveling blade slices the sandwich apart into two identical cut-pile carpets. The technique doubles loom output and explains why the pile of a face-to-face Wilton is always cut — the loops never existed as loops, but as bridges between the two carpets.
A type of carpet made by compressing and matting wool fibers together using heat, moisture, and pressure rather than weaving or tufting. The resulting material is dense, durable, and naturally water-resistant. Modern felted wool carpets combine traditional techniques with contemporary designs for a unique textile that provides excellent thermal and acoustic insulation.
Antique Persian carpets from the Ferahan (also spelled Farahan or Feraghan) plain in central Iran, known for all-over Herati patterns and subtle color palettes. These 19th-century rugs typically feature a diamond lattice of small floral motifs, often in navy blue, rust red and ivory, and are prized for their fine weave and balanced, restrained compositions. In today's trade the name is also used for newly made Pakistani workshop rugs of the Peshawar (Chobi) type, woven from hand-spun wool and vegetable dyes in subdued colors and mostly Persian-inspired all-over designs, and sometimes for Sarouk rugs from the same region; such rugs are not antique Ferahan carpets.
Chemical processes applied to carpets to reduce flammability and meet fire safety standards. Common treatments include applying flame-retardant chemicals during manufacturing.
A type of carpet constructed without pile, where the warp and weft threads are woven together to create a flat surface. Examples include kilims, dhurries, and soumaks. Flatweaves are typically reversible, lightweight, and easier to clean than pile carpets, making them popular for casual spaces and warmer climates.
A type of cut pile carpet with tightly twisted fibers that curl in different directions, creating a textured, casual appearance with excellent durability and ability to hide footprints.
In machine-made carpets, refers to the distance between needles on the tufting machine. Lower gauge numbers indicate more needles per inch and a denser carpet.
A type of Persian carpet from the Heriz district in northwestern Iran, specifically from the village of Gorevan. These rugs feature bold, geometric patterns with large central medallions and corner pieces in rich reds, blues, and ivory. Compared to standard Heriz rugs, Gorevans typically have a coarser weave, more angular designs, and a distinctive rustic character that makes them popular for traditional and transitional interiors.
Environmentally friendly carpet cleaning methods that use non-toxic, biodegradable cleaning agents and reduced water consumption. These approaches minimize chemical residues, decrease indoor air pollution, and reduce environmental impact while still effectively cleaning carpets. Methods may include plant-based cleaners, steam cleaning with minimal chemical use, or encapsulation cleaning that reduces water waste.
The era of Mongol and Ilkhanid rule over Persia, which some rug histories date from the 1300s into the 1500s. It is credited with blending Chinese and Islamic art in Persian carpet design: pictorial, open-space compositions and motifs such as the phoenix, lotus, cloud band and dragon are traced to this contact, and Persian rug weaving as it is known today may have begun here. Little evidence remains, since much of the period's work was destroyed, but rare glimpses of its rugs show floral motifs and birds starting to appear.
A very large government-owned Iranian rug producer, known by the initials ICC and in the United States as the Iranian Rug Company, whose roots reach back to 1934. It runs a network of workshops in about 44 cities, including Tabriz, Hamadan and Sarouk, with some 25,000 workers, and turns out roughly 50,000 square meters (about 540,000 square feet) of rugs a year. It supplies wool and materials and lends money for replacing old looms. Dyeing and weaving are tightly controlled, and even a small flaw has to be unpicked and redone, so its signature signals consistent, high quality whichever town the rug comes from.
Handcrafted carpets from Jaipur, India, known for their vibrant colors and intricate designs. Traditional Jaipuri rugs feature distinctive floral patterns, geometric motifs, and sometimes incorporate block-printing techniques. These rugs often use a cotton foundation with wool pile and are renowned for their craftsmanship, with techniques passed down through generations of artisans in Rajasthan.
Fine Persian carpets from the city of Kashan in central Iran, a weaving center since the 17th-century Safavid era, when the rulers holidayed there and furnished their villas with local rugs. The pile is typically all wool, often imported Manchester wool, of medium height on a cotton foundation; silk-and-wool pieces are mostly older. Designs are formal and vary little: a central medallion, a medallion with matching corner pieces or allover florals, plus a rare design called Darbari, reportedly with little or no border. Rugs of about 5 by 7 feet (1.5 by 2.1 m) and smaller show more variety, such as tree of life, vase and bird patterns. Classic colors are deep red, navy and cream; yellow or green fields are rare, and newer rugs are softer pastels.
Fine Persian carpets from Kerman in southern Iran, a city on the old Iran-India trade route and one of the historic rug-weaving centers, famed for its master dyers. Designs vary widely: florals and allovers, tree of life, hunting, garden and open-field layouts, fine “spring” florals of tiny flowers, and the distinctive “vase” technique. The pile is usually soft kork wool on a cotton foundation, sometimes silk-and-wool or pure silk. One rug can hold 15 to 30 colors, mostly deep reds, several blues, green and cream, with pastels such as champagne, lime green, pink and gray-blue in newer pieces. Roughly half of Kerman rugs, from lesser workshops, use the jufti knot, a shortcut yielding a sparser, lower-quality weave.
The natural wax that coats wool fibers and serves as the fleece’s own protection, waterproofing it. Wool from sheep raised at higher elevations is thicker and oilier ("fatty"), and a warm, slightly oily hand is a quick sign of real wool. In a carpet, the lanolin that remains repels liquids, so spills bead on the surface for a few moments instead of soaking in, one reason wool resists spills and soil. Hand spinning preserves it, while repeated harsh chemical cleaning strips it away, so gentle washing is recommended.
A synthetic rubber compound applied to the back of carpets to secure the tufts and provide dimensional stability. Available in various formulations including SBR (Styrene Butadiene Rubber) and synthetic latex, which offer different levels of flexibility and durability.
A carpet construction where yarn loops are all the same height, creating a uniform, textured surface with excellent durability and soil hiding capabilities.
The frame on which the warp (vertical) threads are strung first and held under tension so the weft (horizontal) threads can be interlaced through them and the knots tied onto them. Hand-knotted rugs are made on simple looms, from those set up in weavers' homes to the compact, transportable ones of nomadic weavers, where every knot is tied by hand. Loom size sets rug size: nomads' small looms typically yield rugs no larger than about 4 x 6 or 5 x 7 ft (1.2 x 1.8 m or 1.5 x 2.1 m), city workshops with very large looms weave palace sizes, and the number of looms a workshop runs gauges its scale. Wooden looms in tribal and village weaving expand and contract over time, one cause of crooked rugs. Power looms such as Wilton, Axminster, and Jacquard, the industrial descendants, make machine-woven carpet.
A carpet construction where the yarn forms loops that remain uncut on the surface. Available in level loop (all loops the same height) or multi-level loop (varying heights to create patterns or texture). Generally more durable and less prone to crushing than cut pile carpets.
A type of Anatolian carpet with a lacy arabesque of yellow scrolling lines on a red ground, named after the Venetian painter Lorenzo Lotto, who showed such carpets in his paintings. The pattern belongs to the late Renaissance, so recognizing it gives a rough age for a rug, although modern reproductions of old designs exist and the pattern alone does not prove that a rug is antique.
Protection of carpets from moths and other pests that eat away natural fibers such as wool and silk, leaving holes and spots that look eaten away, even on newer rugs. Treatment of the fibers is one measure, and mothballs are sometimes used for storage longer than about a year or in moth-prone places, though they leave a lingering odor. The main defense is upkeep: moths favor dark, damp, undisturbed places such as beneath sofas or in storage, so a clean, dry, ventilated rug that is vacuumed under furniture and shaken out and aired every few months is far less likely to be attacked. A rug going into storage is cleaned first and wrapped in breathable material, then unwrapped and checked about every six months if it stays a year or more.
Carpets woven by nomadic tribes across the Middle East, Central Asia, and North Africa, who move with their flocks through spring, summer and fall and settle in winter to weave. Working on compact portable looms, they typically make small pieces (for example 4 x 6 or 5 x 7 ft, about 1.2 x 1.8 or 1.5 x 2.1 m), sometimes runners, using wool from their own flocks, often for both foundation and pile, traditionally dyed with local plants. The bold, mostly geometric designs are passed down through generations without written patterns and sometimes echo city rugs. Unlike city or workshop rugs, they often show asymmetry, color variation and patterns that do not resolve neatly at the corners.
An exceptionally large carpet woven for a grand formal room, in special sizes beyond the standard ranges, roughly from 12 x 18 ft (3.7 x 5.5 m) upward. Such sizes are often made to order, and workshops with access to very large looms and ample resources, as in Sarouk weaving, can produce them. A 13 x 20 ft (4.0 x 6.1 m) Kashan with a medallion-and-corner layout is an example of the scale. Dealers set the threshold differently, so the figure is approximate.
A stylized fan- or palm-leaf-shaped flower motif whose petals or leaves spread from a single base. It is repeated in the fields and borders of city rugs such as Kashan and Tabriz, usually alongside arabesque scrolls, rosettes, and floral sprays. In Sultanabad rugs the palmettes are drawn oversized and set among angular vine scrolls in an allover pattern.
The oldest known pile carpet in the world, woven around the 5th century BC and discovered in 1949 in the frozen tomb of a Scythian noble in Siberia's Altai Mountains. Grave robbers left the burial mound open, so cold and moisture froze the chamber and sealed the carpet in ice for some 2,500 years. Its symmetrical knots, about 36 per square centimeter (roughly 230 per square inch), show that carpet weaving was already a mature art in antiquity. It is often described as the oldest Persian rug and as early evidence of tribal weaving, a craft that began as protection against cold and damp. It is displayed in the Hermitage Museum in St. Petersburg.
A hand-knotted rug woven in Iran, the country called Persia in the West until 1935, in a tradition said to reach back some 2,500 years. It is named after the city, town, region or tribe where it was made (Tabriz, Kashan, Heriz, Baluchi) and belongs to one of three groups: city rugs woven in workshops from a blueprint, village rugs, and tribal rugs, the latter two woven largely from memory. The pile is wool, silk or a blend, on a cotton, wool or silk foundation. Look-alikes woven in Pakistan, India or China are not Persian rugs.
The surface of a rug or carpet, made of upright fibers in cut tufts or loops. In a hand-knotted rug it is formed by the cut ends of thousands of wool or silk knots tied onto the warp row by row, trimmed lightly during weaving and given its final height by shearing at finishing. Pile thickness, measured from the back of the rug to the top of the pile, typically runs from low, about 1/8 to 1/4 inch (3 to 6 mm), to high, about 1/2 to 5/8 inch (13 to 16 mm). Fine, dense designs are cut short to keep the pattern sharp; higher pile suits traffic and heavy furniture, lower pile suits door clearance and humid rooms.
A condition where areas of carpet appear lighter or darker than surrounding areas due to light reflecting differently off pile fibers that have changed direction. Not a manufacturing defect but a physical characteristic of cut pile carpets. Also known as watermarking or pooling.
A professional carpet installation tool that uses leverage and teeth to grip and stretch carpet tightly across a room. Essential for proper installation to prevent wrinkles, ripples, and premature wear. More effective than knee kickers for larger areas.
A rug whose pile is entirely silk, woven on a cotton foundation or on a silk foundation; when both are silk, no wool enters the rug. Silk's fineness allows the highest knot density of any Persian rug, roughly 600 to 1,000 knots per square inch (about 9,300 to 15,500 per 10 x 10 cm), so the pile is kept low to show the design, and the fibers give a luminous sheen that shifts with the light. About 90 percent of Qum rugs are silk on both foundation and pile, as are some Isfahan rugs. These are the most expensive Persian rugs; they are delicate and stains are hard to remove, so they suit display, formal rooms or wall hanging rather than dining rooms or homes with pets.
A carpet tile installation method where each tile is rotated 90 degrees relative to adjacent tiles. This technique helps minimize visible seams, disguises slight color variations between tiles, and creates a more dynamic visual effect, especially with patterned carpet tiles.
A tufting technique in machine-made carpets where tufts are placed in a radial pattern rather than in straight rows, creating more natural-looking designs.
Carpet made from post-consumer or post-industrial recycled materials. May include fibers made from recycled plastic bottles (PET), reclaimed nylon from used carpets, or recycled backing materials.
The process of removing wrinkles and ripples in carpet by pulling it taut and reattaching it to the tack strips. Necessary when carpet becomes loose due to age, humidity changes, or heavy furniture movement.
A round, flower-like ornament in which petals radiate evenly from a center, like a blossom seen from above. From about the 16th century, as floral design entered Persian rugs, weavers began placing a rosette at the center of the field, which produced the central medallion of floral city rugs, as in the circular rosette medallion with scrolling lines on a round Shah Abbasi Tabriz. On Abadeh rugs a small rosette worked in navy, red or cream marks the center of the medallion, one way to tell the type apart. Rosettes also repeat along borders, as in Tabriz and Bakhtiari rugs, and among the vines and palmettes of Sultanabad rugs.
The Isfahan workshop founded in 1940 by Haj Agha Reza Seirafian, a banker who had long traded and produced carpets, and carried on by his family through several generations. It is widely regarded as the best-known name in fine Isfahan rugs, which are densely knotted in fine wool, sometimes with silk, in floral and medallion designs. As in other elite city workshops, the master's name is woven into a border or a small cartouche, which ties the rug to the workshop's strict standards and makes signed pieces sought after by collectors.
A rare classical Persian design of dramatic, curved saber-like leaves sweeping among palmettes and vines, associated with 16th–17th century "vase technique" carpets from Kerman. It holds the world auction record for any carpet: the Clark sickle-leaf carpet sold at Sotheby's in 2013 for 33.8 million dollars, more than tripling the previous record and placing carpets firmly in the territory of masterpiece art.
A dyeing method where color is added to the liquid synthetic fiber solution before extrusion, resulting in colorfast carpets highly resistant to fading and bleaching.
Antique Persian carpets from Sultanabad, the former name of the Arak region of Iran, a newer weaving center that flourished under the Qajars in the late 19th and early 20th centuries and supplied European and American buyers. Their typical layout is an allover field of oversized palmettes, lotus blossoms, floral sprays and angular vines, recalling the Shah Abbasi pattern in a rustic village manner rather than the precise curvilinear drawing of city rugs. Indigo or midnight blue with rust or brick red, gold and olive is a classic palette. Because Sultanabad no longer exists under that name, antique examples are scarce and command higher prices.
A coded script used in Kashmir and Persia to record carpet designs as compact symbols indicating the number of knots and their colors. In traditional workshops a talim reader chants the code line by line — almost like a song — while several weavers knot in unison, allowing one design to be reproduced precisely across looms and generations without the weavers ever seeing a drawing.
A relatively new synthetic carpet fiber known for its exceptional stain resistance, durability, and softness. Often marketed under the brand name Sorona® by DuPont.
A laboratory measure of the force needed to pull a single tuft out of a carpet's backing, usually expressed in pounds or newtons. It is one of the most revealing specs on a carpet datasheet: low tuft bind is what turns a snag into a run, especially in loop pile where one pulled loop can unzip a whole row. Good latexing or thermal bonding raises it dramatically.
A precision cutting technique used in carpet manufacturing where ultrasonic vibrations generate heat to simultaneously cut and seal synthetic carpet fibers. This prevents fraying and creates clean, precise edges for intricate patterns or custom shapes.
A single-layer backing system applied to carpet, typically made of latex or synthetic materials. Unlike traditional carpets with primary and secondary backings, unitary-backed carpets have a single, more substantial backing layer that provides stability and dimensional integrity.
A carpet's ability to withstand fading or degradation when exposed to ultraviolet light. Important for carpets in sunlit areas or outdoor applications. Solution-dyed fibers typically offer superior UV resistance compared to conventionally dyed carpets.
A sampler rug: a small piece woven not for the floor but as a three-dimensional pattern reference, showing sections of borders, medallions, and field designs that a workshop could combine into full-size carpets. Essentially a weaver's catalogue in carpet form, vagirehs let master designs travel between villages without paper. Antique examples, particularly from Bidjar, are now sought-after collector's items in their own right.
A semi-synthetic fiber made from cellulose, used in carpets to create a silk-like appearance at a lower cost. Less durable than wool or synthetic fibers.
The two thread systems that make up a carpet's foundation: the warp, the vertical threads strung on the loom first, and the weft, the horizontal threads passed through them between rows of knots. The foundation is usually cotton, though wool is common in tribal and older rugs and silk in very fine ones. Single-weft rugs, standard in the greater Hamadan area, show zigzag rows of white warp dots on the back and have a thinner pile, whereas double-weft construction, standard in fine, tightly woven rugs and in Bijar and Heriz, hides the warp and gives a thicker, denser pile. The warp ends form the fringe, and extra weft passes at each end form the flat-woven kilim end that secures the pile.
A standardized system that indicates the durability of carpet and its suitability for different levels of foot traffic. Often expressed as light, medium, heavy, or extra heavy residential or commercial use.
A drawn design plan, also called a blueprint, that a workshop weaver follows knot by knot. In the Safavid period, as patterns grew more complex, separate designers, often miniature painters, are said to have drawn them on such plans, so that weavers only carried out others' designs, and weaving schools grew up around this way of working. City rugs from workshops in places such as Tabriz and Isfahan are so precise because they are woven from such plans. Village weavers rely on plans much less, and tribal weavers work from memory and from designs handed down within the family, so their rugs tend to be less symmetrical.
The capillary action by which a spill absorbed deep in the backing climbs back up the pile as the carpet dries — the reason a "removed" stain can reappear a day after cleaning. Professionals defeat wicking by extracting moisture thoroughly and drying fast, or by placing weighted absorbent pads over the spot overnight. If a stain keeps returning, the residue below the pile, not the fiber, is the culprit.
A type of woven carpet made on a Wilton loom, known for its dense construction and ability to create intricate patterns. Often considered higher quality than tufted carpets.
In carpet manufacturing, refers to exceptional or unique features that distinguish a particular carpet from others, such as proprietary stain resistance technologies or exclusive fiber blends.
A proprietary stain and soil resistance treatment applied to carpet fibers that creates a molecular shield around each fiber. This technology repels liquids and prevents stains from bonding to the carpet, making cleaning easier and extending the carpet lifespan.
A specialized tufting technique where the needles create an X-pattern in the carpet backing rather than straight rows. This method increases tuft bind strength and creates a more stable, durable carpet construction that resists pile distortion in high-traffic areas.
Outdoor carpet products specifically designed for water conservation landscaping (xeriscaping). These carpets are typically made from drought-resistant synthetic materials that require minimal maintenance and water, while providing an aesthetic alternative to natural grass in arid environments.
The use of woodblock printing techniques to create patterns on carpets or to transfer designs onto weaving templates. This ancient technique involves carving designs into wooden blocks, applying dye, and stamping the pattern onto fabric or paper.
Various techniques for coloring carpet yarns, including beck dyeing (immersion in dye baths), continuous dyeing (application after tufting), space dyeing (multiple colors on a single yarn), and solution dyeing (color added to liquid polymer before extrusion). Each method offers different benefits for colorfastness, pattern capabilities, and environmental impact. In hand-knotted rugs the wool is dyed as spun yarn before knotting, with natural dyes from plants, roots, and flowers, which tend to mellow with age, or with synthetic dyes; differences between dye batches are a main source of abrash.
The number of single yarns twisted together to form a carpet yarn. Two-ply or three-ply yarns are stronger and more durable than single-ply yarns. In hand-knotted rugs, wool is first spun into threads, by hand or on a wheel, and those threads are then twisted together into thicker, sturdier strands before the yarn is dyed.
A traditional method of dyeing carpet yarn in which loose skeins (loops) of already spun, plied yarn are immersed in dye baths before the yarn is knotted or woven into the rug. This technique, common in handmade carpets, works in separate batches, and small differences between batches, together with differences in the natural fat of the wool, produce the subtle color variations known as abrash that give traditional rugs their characteristic depth and visual interest. The process is still used by artisans who create custom-dyed yarns for specialty carpets.
The number of turns per inch in carpet yarn. Higher twist levels generally provide better durability and appearance retention, particularly in cut pile carpets.
Fine Persian carpets from the city of Yazd in central Iran, known for their intricate medallion designs and high-quality craftsmanship. Traditional Yazd carpets feature a central medallion with elaborate floral motifs, often incorporating silk highlights on a wool foundation. The color palette typically includes rich blues, reds, and ivories with distinctive curvilinear patterns influenced by the historic textile traditions of this ancient city.
Tribal carpets woven by the Yoruk (Yürük) nomadic people of Anatolia and the Balkans. These distinctive rugs feature bold geometric designs, vibrant colors, and tribal symbols with cultural significance. Characterized by their coarse weave, sturdy construction, and use of natural dyes, Yoruk rugs often incorporate protective motifs and symbols representing fertility, family, and tribal identity.
A category of carpets with extremely low or non-existent pile height, including flat-weaves and certain low-profile commercial carpets. These floor coverings offer durability, easy maintenance, and accessibility benefits while providing sound absorption and comfort underfoot. Popular in high-traffic commercial spaces, healthcare facilities, and modern residential interiors where a minimal profile is desired.
A type of Persian carpet first made in the late 19th century for the European market by the firm Ziegler & Co., with enlarged, modified traditional Persian designs in softer, muted colors suited to Western tastes. A Ziegler Mahal design marks a particular period of production, yet old Ziegler patterns are still reproduced today, so design alone cannot date a rug. The name is also one of several trade names, alongside Oushak, Peshawar, Chobi and Farahan, used for workshop rugs made in Pakistan since roughly the 1970s in traditional Persian and Turkish designs, with a wool pile on a cotton foundation; which name applies varies with design and knot density.
The practice of using different carpet types or designs to define separate functional areas within a larger space. Common in open-plan environments where changes of carpet can subtly mark transitions between work, relaxation, or circulation zones without physical barriers. With area rugs, a single rug can anchor a zone where there are no walls, and two rugs can split a large living room into two functions; rugs in neighboring spaces read as connected when they share a type, design or colors, and as separate when their colors and patterns differ.
