A study of the strength development (mullen and tear) of mixtures of "easy" and "hard" refining pulp, in which the pulps were refined as a mixture with that in which they were separately refined, and then mixed, reveals that separate refining develops mullen to the same extent as does mixed refining, but that a higher tearing resistance at the same freeness and mullen can be obtained with separate refining.
