发明名称 Dry deinking of secondary fibres
摘要 <p>Ink-bearing secondary fibre feedstocks are deinked by mechanically fiberizing the feedstocks in a substantially dry state to produce substantially discrete fibres and fines and separating the fines from the fibres. The feedstock may be shredded printed waste paper. Fiberisation may be effected in any conventional fiberisation equipment. Separation of fines from fibres may be carried out using a mesh bag, or a continuously moving wire screen, preferably with the assistance of a vacuum box. The fibres recovered may be cleaned by aqueous centricleaning, or by wet deinking methods.</p>
