Wool yarn spun from cleaned, carded fleece by hand or on a manual wheel rather than by machine, after which the spun threads are twisted together into thicker, stronger strands before dyeing. It gives finer, softer threads than machine spinning, so the wool feels softer and looks shinier, and hand spinning is said to preserve the wool's natural lanolin. It is usual in Kazak and Peshawar rugs woven in Pakistan and in Afghan Khal Mohammadi rugs, all of which are also colored with natural dyes.
A fine, soft grade of wool taken from the neck and inner fleece layer of young sheep, often from the first shearing. Oily with natural lanolin, it feels soft and resilient and gives colors extra shine. It is used for the pile of many fine city rugs from Isfahan, Kerman, Qum, Tabriz, and Mashad, and older antique Sarouks cut to a short pile use it too. Also spelled cork or kurk wool.
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.
The root of the madder plant (Rubia tinctorum), a natural red dye and the source of the terracotta tones in Persian and Oriental rugs. Together with indigo and walnut husks it is among the plant dyes used to color the wool, bonding to its natural lanolin. Slight shade variations within one color area, known as abrash, are normal in rugs dyed this way.
A former Mashhad (Mashad) workshop whose rugs, no longer woven, are hard to find and are regarded as collectors' pieces. Typical examples have a cream ground with delicate floral designs on very thin branches, an allover layout with only a vaguely defined central medallion, and soft, subdued colors such as peach, blue and cream. The wool is described as soft, lanolin-rich wool from young sheep, which makes the colors look shinier. Weaving reportedly ended by the mid-1980s, because the next generation did not want to continue.
