Calculation of percentage masses of clean dry fibre, disregarding loss in fibre mass during pre-treatment:

P_{1} % = \frac{{100 m}_{1}}{m_{1} + m_{2} + m_{3}} = \frac{100}{1 + \frac{m_{2} + m_{3}}{m_{1}}}

P_{2} % = \frac{{100 m}_{2}}{m_{1} + m_{2} + m_{3}} = \frac{100}{1 + \frac{m_{1} + m_{3}}{m_{2}}}

P ₃% = 100 – (P ₁% + P ₂%)

P₁%

is the percentage of the first clean dry component,

P₂%

is the percentage of the second clean dry component,

P₃%

is the percentage of the third clean dry component,

m₁

is the clean dry mass of the first component,

m₂

is the clean dry mass of the second component,

m₃

is the clean dry mass of the third component.
