Adsorption of Xylan onto Cellulose Fibers Pretreated with Cationic Polyelectrolyte and Its Effect on Paper Properties

“…Physical strength increased significantly with xylan adsorption. These results are in accordance with Maximova et al (2001), who reported on the pre-adsorption of PDADMAC onto fiber surfaces with lignin. Both tensile and tear indices of paper increased, as shown in Figs.…”

Addition of Ascorbic Acid or Purified Kraft Lignin in Pulp Refining: Effects on Chemical Characteristics, Handsheet Properties, and Thermal Stability

“…Similar lignin aggregates on the surfaces of bleached fibers were not previously observed with SEM (Vänskä and Vuorinen 2015). In particular, Maximova et al (2001) also found granules on the fiber surface after adsorption of lignin onto cellulose fibers.…”

“…Figure 3 shows that although the pulps had similar strength properties prior to refining, the tensile indices of the FBP+L handsheets improved marginally more than the reference handsheets (FBP) upon refining. A modest strength improvement was also observed when the precipitated kraft lignin was adsorbed on the surface of fibers (Maximova et al 2001). Furthermore, in a microfluidization study of high yield pulp, the mechanoradical scavenging capacity of lignin was suggested to improve the strength properties of nanopaper (Ferrer et al 2012).…”

CHAPTER 4. Water-Soluble Antimicrobial Polymers for Functional Cellulose Fibres and Hygiene Paper Products

“…The driving force for such an adsorption is the electrostatic attraction between the cationic groups of PHGH-modified starch and anionic groups of fibres. 17 The antimicrobial polymer adsorbed more on recycled fibres than on sulfite fibres because of the higher surface charge densities and specific surface areas of recycled fibres. Meanwhile, the adsorption conditions including temperature, ionic strength and pH can influence the adsorption process and intrinsic electrostatic interaction between guanidine-modified starch and cellulose fibre.…”
