Abstract
The use of stearic acid, which has no double bonds in its carbon chain , removes much more ink from the fibre in the pulper and gives the bes t overall efficiency of deinking (pulping and flotation) compared with oleic or linoleic acid. The separation of ink from the fibres and the overall efficiency of the deinking process increase with the addition of silicate for unsaturated fatty acids with two double bonds. This p aper examines also the influence of the number of separated ink partic les on the optical properties of the paper.
