Ghiordes Knot
Turkish Knot: One of the two primary knot types used in hand-knotted carpets, where the yarn is wrapped around two adjacent warp threads and then pulled back between them. This symmetrical knot creates a stronger, more durable carpet but allows fewer knots per square inch than the asymmetrical Persian knot. Named after the town of Ghiordes (modern Gördes) in Turkey, it is commonly used in Turkish, Caucasian, and some Persian carpets.
Gul
Gol: An octagonal or polygonal medallion motif commonly found in Turkmen tribal rugs. These distinctive medallions serve as tribal emblems, with each Turkmen tribe (Tekke, Salor, Ersari, etc.) having its own characteristic gul design. The word means "flower" or "rose" in Persian, though the designs are highly geometric and stylized rather than floral in appearance.
Gorevan Carpet
Heriz Gorevan: 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.
Green Cleaning: 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.

H

Jajims feature colorful stripes and simple geometric patterns, often in bright blues, reds, and yellows. Historically used as floor coverings, bedspreads, or wrapping cloths by nomadic tribes, they are now appreciated as decorative textiles and wall hangings.
Jufti Knot
False Knot: A carpet knotting technique where the yarn is wrapped around four warp threads instead of the usual two (Turkish knot) or one-and-a-half (Persian knot). This shortcut allows weavers to create carpets more quickly but results in lower knot density and potentially reduced durability. Jufti knotting is sometimes used in commercial production to speed up the weaving process while maintaining the appearance of a densely knotted carpet.

Pile Crushing: The flattening of carpet fibers in high-traffic areas or under heavy furniture, resulting in a worn appearance. Can be minimized by selecting carpets with higher density, proper padding, and regular maintenance including vacuuming and professional cleaning.
Power Stretcher: 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.
Persian Knot
Senneh Knot: One of the two main knot types used in hand-knotted Oriental rugs (the other being the Turkish/Ghiordes knot). The Persian knot is asymmetrical, with yarn wrapped around one warp thread and then passed behind the adjacent warp thread. This technique allows for more intricate, curvilinear designs and higher knot counts, making it preferred for detailed floral patterns in Persian rugs.
Prayer Rug: Small rugs designed for Islamic prayer rituals, featuring a mihrab (arch) design that indicates the direction of Mecca.

X

X-Factor: 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.
X-Stitch Tufting: 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.
Xeriscaping Carpets: 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.

Xylography in Carpet Design: 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.

Y

Yarn Twist: The number of turns per inch in carpet yarn. Higher twist levels generally provide better durability and appearance retention, particularly in cut pile carpets.
Yarn Ply: 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.
Yarn Dyeing Methods: 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.

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.
Yarn Skein Dyeing: A traditional method of dyeing carpet yarn where loose skeins (loops) of yarn are immersed in dye baths before being spun and woven. This technique, common in handmade carpets, allows for 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.

These distinctive rugs feature bold geometric patterns, vibrant colors, and tribal motifs that reflect the cultural heritage of groups like the Bakhtiari, Qashqai, and Luri. Characterized by their sturdy construction, natural dyes, and designs that tell stories of mountain life and tribal traditions.
Zilu
Zili: A traditional flat-woven textile from Iran, particularly the Yazd and Meybod regions. These cotton or wool floor coverings feature geometric patterns created using a special weaving technique that produces a reversible fabric with different patterns on each side. Historically used in mosques and homes, zilus typically display blue and white patterns with cultural and religious significance.
Zero Pile Carpet: 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.
