Machine-spun wool

Machine-spun wool is carded and spun in a mill, so the yarn is even in thickness and twist and generally takes dye more evenly. Machine-spun yarns were reaching Persian weaving by the late 19th century, and in the 20th century the state Iran Carpet Company ran its own factories for washing and combing, carding and spinning wool. It is normal in later production and is not a fault, but it is one of the yarn signs read in dating.
