day whereafter the samples were thinned with hot water and pulped defibered sheets were then produced at mutually different ph values in accordance with the network strength sheet method described above the ph of the pulp was adjusted to ph values of between 2 and 11 prior to and optionally subsequent to the wet pulping process this procedure provided many measuring points which improves the reliability of the process and which also illustrates the effect of the ph value on the fluff properties subsequent to conditioning the sheets the sheets were pulped in a braun kitchen mixer for 30 seconds the following results were obtained __________________________________________________________________________ph before reference pulp lipase treated pulpsheet abs abs fract dcm abs abs fract dcming ph bulk nvs vol time cap rest extr ph bulk nsv vol time cap rest extr __________________________________________________________________________2 3 4 18 8 3 3 16 3 274 6 11 1 0 47 3 4 20 2 4 7 16 6 12 4 11 2 0 473 4 5 18 4 3 2 15 4 102 8 11 7 0 36 4 7 19 6 4 6 16 6 11 6 10 9 0 334 5 4 18 4 2 8 15 8 114 7 11 7 0 36 5 6 19 6 4 1 17 0 12 1 11 2 0 355 6 7 18 8 3 1 15 8 93 2 11 2 0 32 6 4 19 6 3 9 16 9 10 6 11 0 0 186 7 6 19 2 3 1 15.
