There are many yarn count systems in the world, so here are a few that are used for coned yarn with industrial standards.
Numero metric count
The numero metric yarn count ‘Nm’ is used the most for industrial yarn in Europe and Asia, which is why we chose to mainly work with this. This metric numbering system (Nm) indicates ‘number of 1000m (or 1 km) of yarn per 1kg weight’.
A few examples:
- Nm30 = 30 km of yarn weighs 1 kilogram. These yarns have the same yarn weight:
- Nm30 is only 1 end of yarn
- Nm60/2 is two ends of yarn, both Nm60.
- Nm120/4 is 4 ends of yarn, each Nm120.
- Nm6 = 6 kilometer of yarn weighs 1 kilogram. These yarns have the same yarn weight:
- Nm6 is only 1 end of yarn
- Nm12/2 is two ends of yarn, both Nm12
- Nm24/4 is four ends of yarn, each Nm24
- Nm8 = 8 kilometer of yarn weighs 1 kilogram. These yarns have the same yarn weight:
- Nm8 is only 1 end of yarn.
- Nm16/2 is two ends of yarn, both Nm16
- Nm32/4 is four ends of yarn, each Nm32
Tex
Tex indicates ‘how many grams of yarn per 1000m’.
Example:
- 30Tex means that 30 grams of yarn are 1000m long. Decitex (dTex) indicates how many grams of yarn per 10000m.
Denier
Denier (DEN) is often used for nylon stockings and tights. It indicates ‘how many grams of yarn per 9000m’.
Example:
- 30D means that 30 grams of yarn are 9000m long.
For Nm, dtex and DEN applies: ‘The higher the number, the finer the yarn’.
As the machine works best with industrial spun yarn on cones, you can compare this industrial used yarn count to a light fingering or 2 ply hand knitting yarn (needle size around 2mm).
Note: Hand knitting yarns are almost always not suited for Kniterate.
