Rawr Denim explains (Yarn) Count
Yarn count refers to the thickness of a yarn and is determined by its mass per unit length. It is usually measured by the number of grams per one kilometer of yarn, a unit of measure called “Tex”.
However, the spinning industry tends to use English cotton count, which is determined by the number of yarn hanks (each 840 yards long) per pound of yarn, and is notated “Ne”.
In this system, the larger the number the finer the yarn and vice versa. The yarn count for denim ranges from Ne 4.0 to Ne 12.5, with lighter weight fabrics such as chambray ranging from Ne 12.5 to Ne 30.0.
