摘要

The invention relates to a noil for use in paper manufacture, to be mixed in mixed in the paper pulp. The noil has been produced from cellulose fibre by refining and consists of noil fibrils that, in respect of size distribution, mainly correspond to wire screen fraction P50, and the noil constitutes 0.1-15 w-% of the paper pulp. ;The invention also relates to a corresponding method for producing said noil. In the method, cellulose fibre is refined so as to form noil fibrils that mainly correspond in size distribution to wire screen fraction P50. ;In addition, the invention relates to a paper pulp that contains said noil, and to corresponding paper.
