Direct System: In direct system length will be fixed and
weight will be changeable of a sample (yarn). In this system of number increase
than the yarn will be coarser and if decrease then the yarn will be finer.
Example: Tex, Denier.
Direct system:
Yarn Count = W×l/L
W = Weight of the sample
l = Length of unit
L = Length of sample
Indirect System:
In indirect system length will be changeable and weight will
be fixed of a sample. In this system of number increase then the yarn the yarn
will be finer and if decrease then the yarn will be coarser.
