yarn numbering system is very important part and it require good knowledge to calculate yarn count, tex, denier of any yarn
Yarn Number
Yarn number is a measure of the fineness or size of a yarn expressed either as mass per unit length or length per unit. Yarn Count and Yarn Size are synonymous with Yarn Number.
Yarn Numbering System
There are two systems of expressing yarn number or yarn count.
❶ Direct yarn numbering system (mass/unit length)
❷ Indirect yarn numbering system (length/unit mass)
Direct yarn numbering system
In a direct yarn counting system, the yarn number or count is the weight of a unit length of yarn. This means the higher the yarn count number, the heavier or thicker the yarn. It is fixed length system. This system is generally used for jute or silk yarn.
Denier: In the direct Denier system, the yarn count number indicates “the weight in grams of 9000 meters of yarn”.
e.g. 30D indicates that 9000 meters of yarn weight 30 grams.
Tex: In the direct universal Tex system, the yarn count number indicates “the weight in grams of 1000 meters of yarn”.
e.g. 30 Tex indicates that 1000 meters of yarn weight 30 grams.
Dtex: In the direct Decitex system, the yarn count number indicates “the Adobe Illustrator weight in grams of 10000 meters of yarn”. (1 dtex=0.9 denier)
e.g. 50 Tex indicates that 1000 meters of yarn weight 30 grams.
Indirect yarn numbering or counting system
In an indirect yarn counting system, the yarn number or count is the number of “units of length” per “unit of weight” of yarn. This means the higher the yarn count number, the finer or thinner the yarn. It is based on the fixed weight system. This system is generally used for cotton, woolen, worsted and linen yarn.
The following formula is used to calculate indirect yarn count system.
English Cotton Count (Ne): In the indirect English cotton count system, the yarn count number indicates “number of 840 yard hanks of yarn per 1 pound weight”.
e.g. 30/1 cotton(1 means single yarn) indicates that 30 x 840 yards of yarn weight 1 pound.
e.g. 40/2’s (2 means ply yarn) indicates that 20(Resultant count)x 840 yards of yarn weight 1 pound.
Metric Count (Ne): In the indirect metric count system, the yarn count number indicates “number of 1000 m (or 1 Km) of yarn per 1 Kg weight”.
e.g. 30 Nm indicates that 30 kilometers or 30000 meters of yarn weight 1 kilogram.
Worsted Count: In the indirect worsted count system, the yarn count number indicates “number of 560 yards hanks of yarn per 1 pound weight”.
e.g. 1/20 worsted indicates that 20 x 560 yards of yarn weight 1 pound.
e.g. 3/40 worsted indicates that 13.33(Resultant count)x560 yards of yarn weight 1 pound.
50 Nm Metric indicates that 50 x 256 yards of yarn weight 1 pound.
