As the example of hardwood pulp, for the most part the hardwood sulphate bleached pulp was investigated about its strength development through beating action comparing with the other pulp both in the labolatory and mill scale.
The improvement of the inferiority of short fiber length specific to the hardwood pulp was discussed in connecting with the cutting resistance. The sulphate pulp has much cutting resistance than sulphite pulp, therefore after beating the fiber length distribution of the hardwood sulphate bleached pulp was similar with the softwood sulphite bleached pulp. This will manifest the character of the strength development of the former through beating to some extent. On the other side, each beating equipment had the specific character of cutting action.
Finally we proved that the fiber length had the secondary effect upon the strength which was made and the primary effect was the interfiber bonding of the fiber with the excepting of the tearing strength.
