Rug glossary · 57 terms

Rug words, plainly defined.

Every rug word that matters, from abrash to yarn count — written by people who use them on the floor.

Abrash
Abrash is the deliberate or natural variation in dye colour across a rug, produced by using yarn from different dye lots or hand-dyed hanks — a signature of hand-dyed, hand-woven work rather than a defect.
Bamboo silk
Bamboo silk is a regenerated-cellulose viscose fibre spun from bamboo pulp with a silk-like sheen — a plant-derived material with the look of real silk at a gentler price.
Berber
Berber refers to a family of North African rug styles, typically hand-knotted or hand-loomed, with tribal geometric motifs on an ivory ground; Beni Ourain and Boujaad are two well-known Berber rug traditions.
Binding
Binding is the finishing stitch that seals the edges of a rug — over-serged, over-locked or hand-bound — keeping the perimeter from unravelling.
Border
Border is the framing band that surrounds the main design field of a traditional rug, usually a repeating motif such as boteh or floral trellis.
CAD (rug design)
CAD in rug design is a digital drawing of the rug pattern converted into a knot map that weavers read at the loom.
Carding
Carding is the mechanical combing of raw fleece into aligned webs of fibre, removing debris and preparing the fibre for spinning into yarn.
Chain stitch
Chain stitch is an edge-finishing technique used on many flatweaves and dhurries, forming a loop-in-loop chain along the border.
Colorway
Colorway is a specific palette a rug design is produced in; the same design can be issued in multiple colorways, each specified against Pantone references or shade cards.
Cut pile
Cut pile is a construction where every pile knot or tuft is cut open at the top, producing a plush, uniform surface.
Dhurrie
Dhurrie is an Indian flatweave rug, traditionally woven from wool or cotton, without pile and typically reversible.
Field
Field is the central area of a traditional rug design, framed by the border, on which the main motif sits.
Flatweave
Flatweave is a rug construction with no pile — the design lives entirely in the interlaced warp and weft. Dhurries and kilims are the classic flatweaves.
Fringe
Fringe is the exposed ends of the warp threads at the top and bottom of a hand-knotted or hand-loomed rug — structural, not decorative.
GSM
GSM stands for grams per square metre — the weight of pile material per square metre of rug, the most objective single measure of how much material a rug contains.
Gabbeh
Gabbeh is a traditional tribal-style hand-knotted rug with bold geometric motifs and a thick, shaggy pile.
Hand-knotted
Hand-knotted describes a rug in which every knot is tied by hand around the warp threads on a loom — the most durable and valuable rug construction.
Hand-tufted
Hand-tufted describes a rug made by punching yarn through a stretched canvas with a tufting gun, then latexed and backed. Rich pile and detailed design at faster lead times than hand-knotted.
Handloom
Handloom describes a rug woven on a traditional loom, with pile inserted between rows of weft — a clean, refined construction without latex or backing.
Heat-set yarn
Heat-set yarn is synthetic yarn treated with heat to lock its twist — used mostly in machine-made carpets, not traditional handmade rugs.
Hank dyeing
Hank dyeing is the practice of dyeing loose skeins of yarn (hanks) rather than piece-dyeing a finished rug — the traditional and honest way to colour handmade rug yarn.
Jute
Jute is a rain-fed plant fibre grown in the Ganges delta, spun into a rustic yarn with visible slubs. Fully biodegradable and carbon-absorbing as a crop.
Kilim
Kilim is a traditional flatwoven rug from Turkey, Central Asia and Iran, produced with slit-weave or tapestry techniques.
Knot count (KPSI)
Knot count, expressed as KPSI (knots per square inch), measures how many hand-tied knots fit in one square inch of a hand-knotted rug. Higher counts allow finer design detail.
Lab dip
Lab dip is a small dyed yarn sample produced in the dye house and sent to the buyer for approval, proving the exact colour before bulk dyeing begins. Turnaround is around 10 days.
Latexing
Latexing is the application of a controlled latex layer to the back of a hand-tufted rug, locking the tufts in place before a secondary backing is applied.
Loom
Loom is the frame on which a rug is woven — typically vertical for hand-knotted work, horizontal for many handloom constructions.
Loop pile
Loop pile is a construction where the pile yarn is looped rather than cut at the top — producing a more textural, matte surface.
Medallion
Medallion is a central ornamental motif in classical Persian and Oriental rug designs, often surrounded by corner spandrels.
Overtufting
Overtufting is inserting extra tufts of yarn on top of a woven surface to add height or accent detail.
PET yarn (recycled)
PET yarn is polyester yarn made from recycled polyethylene terephthalate — typically post-consumer PET bottles. Certified under GRS.
Persian knot (Senneh)
The Persian or Senneh knot is an asymmetric hand-tied knot where the yarn wraps around one warp and passes behind the other; allows finer detail than the Turkish knot.
Pile
Pile is the raised yarn surface of a rug that you walk on — created by knotting, tufting or inserting looped or cut yarn between rows of weft.
Pile height
Pile height is the length of the pile yarn from base to tip, typically 6–15 mm on handmade rugs.
Pitch
Pitch is the density of warp threads across the width of the rug, expressed as knots or warps per unit length.
Ply
Ply is the number of individual yarn strands twisted together to form the final rug yarn.
Pot dyeing
Pot dyeing is small-batch dyeing of individual yarn hanks in a single pot — the traditional approach for special colours and small runs.
Runner
Runner is a long, narrow rug typically used in hallways, kitchens or beside beds.
Selvedge
Selvedge is the vertical finished edge of a rug where the wefts turn back and the rug is bound — the equivalent of a hem on fabric.
Shearing
Shearing is the mechanical levelling of the pile to a uniform height as part of finishing.
Shedding
Shedding is the loss of loose surface fibre from a new wool rug in the first weeks to months of use — normal and self-limiting.
Shuttle
Shuttle is the wooden tool that carries weft yarn back and forth across the warp on a handloom.
Sisal
Sisal is a plant fibre from the agave plant, spun into a coarse durable yarn used mostly in flatweave rugs.
Space dyeing
Space dyeing is dyeing sections of a yarn hank in different colours so the finished yarn creates a mottled pile.
Strike-off
Strike-off is a physical rug sample produced from an approved CAD, sent to the buyer for approval before bulk production — typically 15 days.
Stretching
Stretching is the finishing step of pinning and pulling a washed rug to true its shape to the specified dimensions.
TPX/TCX (Pantone)
TPX and TCX are the Pantone colour reference codes used for textiles (TPX printed, TCX cotton). Rug yarn is dyed to match a given TPX or TCX reference through lab dips.
Tencel
Tencel is a lyocell fibre made from wood pulp (typically eucalyptus), with a silk-like sheen and low environmental impact production process.
Tibetan knot
The Tibetan knot is tied around a rod inserted horizontally on the warp; when the rod is pulled out the loops open, producing a distinctive pile.
Tufting gun
Tufting gun is the hand-held tool used to punch yarn through the canvas backing in hand-tufted rug construction.
Turkish knot (Ghiordes)
The Turkish or Ghiordes knot is a symmetric hand-tied knot that wraps around two warp threads — more robust than the Persian knot at lower knot counts.
Viscose
Viscose is a regenerated-cellulose fibre spun from wood pulp or bamboo pulp, with a silk-like sheen. Sensitive to moisture.
Warp
Warp is the set of parallel threads strung vertically on the loom, around which knots are tied or through which wefts are woven.
Weft
Weft is the yarn that runs horizontally across the loom, interlacing with the warp and bedding each row of knots or forming the flatweave surface.
Wool (NZ vs Indian)
New Zealand wool is longer-staple, whiter and finer, ideal for pastel palettes and whites; Indian wool is shorter-staple, springier and more resilient, ideal for body and value. Many qualities blend both deliberately.
Yarn count
Yarn count is the specification of a yarn's thickness, expressed in various count systems depending on the fibre — a higher count typically means a finer yarn.
