摘要

Short fibers obtained by fractionating waste paper reduce in the course of processing of waste paper the bonding properties of long fiber fractions. According to this invention the short fiber fractions are first separated from the long fiber fractions, the long fiber fractions regenerated by milling, advantageously by fibrillation milling, and subsequently at least part of the earlier separated short fiber fraction added to the regenerated long fiber fraction for further processing.
