    One such method is INGEDE Method 11. It was developed to simulate the deinking of offset printed mechanical fiber (newsprint) including supercalendered (SC) and light-weight coated (LWC) paper grades. A limitation of Method 11 is that it incorporates single-loop flotation as the primary processing step for deinking.

    2021-6-16 · The authors attributed much of their success in cell-wall filling to their use of never-dried refined kraft fibers for which the cell wall pore volume tends to be relatively large e.g. 2 cm 3 /g. Drying of fibers is known to result in semi-permanent closure of pore spaces in the cell walls of fibers (Stone and Scallan 1966 Hubbe et al. 2003).
