The effect of wet pressing and drying on bonding and activation in paper - The effect of wet densification on interfibre bonding and fibre segment activation was studied by subjecting hand sheets to varying wet pressing pressures. Drying stress was also used as a variable. Paper strength properties, measured from dried sheets, were used as means to examine bonding and activation.Vainio, Anna et al. | 2007

Pulp bleaching with peracetic acid generated from acetylated polymeric carbohydrates and hydrogen peroxide -- Proof of principle - Peracetic acid has been considered a promising bleaching chemical for TCF sequences for more than a decade. Availability has been one obstacle preventing its wider use. This article presents an inexpensive way for in situ-generation of peracetic acid, but also tries to evaluate its true potential in pulp bleaching. This potential, even in TCF bleaching, remains questionable.Backa, Stefan et al. | 2007

Modification of the surface chemistry of TMP with enzymes - The surface chemistry of TMP was modified with specific enzymes and the effects of the enzymatic treatments on the surfaces of pulp, fibers and fines were studied using ToF-SIMS, ESCA and contact angle analysis. The treatments had a pronounced effect on the surface extractives, especially those on fibrillar fines.Kangas, Heli et al. | 2007

Acoustic characterisation of film splitting in a HSWO printing nip - This article shows that critical print variables such as ink tack, ink-water balance and paper surface properties on a heat-set web offset press can be monitored through on-line acoustic analysis of the print-nip film splitting noise.Voltaire, Joakim et al. | 2007

Acoustic emission and tack of heat-set inks during setting on MWC-papers and fountain solution emulsification - The tack and acoustic signal due to film splitting at the nip exit of laboratory offset test printing instruments were measured simultaneously. These two responses and their behaviour during ink setting and fountain solution emulsification could be directly compared.Voltaire, Joakim et al. | 2007

Quantification of paper mass distributions within local picking areas - A new method for analyzing paper structure and local print details revealed detailed information about the influence of formation on picking. The method also seemed to be suitable for assessing the local characteristics of several paper and print relationships.Chinga, Gary et al. | 2007

Effects of selective wood resin adsorption on paper properties - Paper handsheets were made in the laboratory to simulate the effects of wood resin adsorption on different types of spruce TMP fines. The results strongly suggested selective adsorption of sterically stabilized wood resin on the flake-like fines at elevated electrolyte concentrations. This was clearly reflected in the optical and strength properties of the sheet.Johnsen, Ingvild A. et al. | 2007

Study on metal ion affinities to oxygen delignified hardwood kraft pulp by a column chromatographic method - Sorption of metal ions to oxygen bleached hardwood kraft pulp was studied by a column chromatographic method. An ion exchange mechanism was used to explain differences in the sorption behavior of different ions.Södö, Maria et al. | 2007

Paper properties of TMP and CTMP handsheets from spruce, as affected by the press load and temperature during sheet drying - The dependence of the properties of handsheets from different mechanical pulps on pressure and temperature during pressing and drying was investigated. High freeness pulps were more sensitive than low freeness pulps to the choice of pressure and temperature levels.Klinga, Niklas et al. | 2007

Paper properties of TMP and CTMP handsheets from spruce, as affected by the solids content from pressing - The dependence of the properties of dry handsheets from different mechanical pulps on the level of dryness to which the sheets were pressed was investigated. The most important dryness interval for internal strength development was found to lie between 50 and 80%.Klinga, Niklas et al. | 2007

Contamination of paper machine press fabric materials by ASA studied with a new deposition tester - The contamination of paper machine press fabrics was studied using a new deposition tester. The results indicated trends similar to those observed in more fundamental laboratory experiments. Thus, the tester provides a connection from fundamental interactions to mill scale applications.Lindfors, Juha et al. | 2007

Degradation-dissolution of softwood hemicellulose during alkaline cooking at different temperatures and alkali concentrations - The behaviour of (galacto)glucomannan and (arabinoglucurono)xylan during soda cooking of softwood meal (Pinus sylvestris) was examined. To assure accurate data, the temperature profile was measured and the alkali concentration was kept virtually constant during the cooks.Wigell, Alexandra et al. | 2007

Kinetic modelling of (galacto)glucomannan degradation during alkaline cooking of softwood - A reaction kinetic model describing the yield loss of (galacto)glucomannan during alkaline cooking of softwood meal (Pinus sylvestris) was developed. The proposed model, based on the chemical reactions peeling, stopping and alkaline hydrolysis, described the glucomannan yield loss very well.Wigell, Alexandra et al. | 2007

Simulated structure of wet fiber networks - Analytical models and computer simulations were utilized to examine the number of inter-fiber contacts for pressed and stretched three-dimensional fiber networks. Computer simulations were more relevant for flocculated and stretched sheets, where the simplifications of analytical models are not valid any longer.Miettinen, Pasi P.J. et al. | 2007

Gibbs energy analysis of ink oil imbibition during ink setting - The specific Gibbs energy change when ink oil is imbibed into coatings was calculated from capillary pressure, volume, liquid surface tension, and contact angle. The energy was proportional to the total capillary surface area, and correlated well with the time to reach maximum ink tack, suggesting that the specific Gibbs energy may be used for characterization ink interaction with coatings.Ma, Deqiang et al. | 2007

Global description of refiner plate wear in low consistency beating - An unambiguous method to characterize the bar edge rounding was proposed. It was pointed out that bar edge wear is a function of the position on the disc surface and of the pattern geometry for discs made of the same steel. Extended gap clearance measurements also indicated a conical-shape wear of the disc surface.Bordin, Ruben et al. | 2007
