fibre form by grinding it against a quickly rotating stone under addition of water. The yield* of this pulp amounts to approx. 95%. The result is called wood pulp or MP – mechanical pulp. The disadvantage of this type of pulp is that the fibre is strongly damaged and that there are all sorts of impurities in the pulp mass.
