“…According to Tay et al (2010), soda pulp from EFB fiber shows a low probability to agglomerate, a high aspect ratio, and better distribution when incorporated into polypropylene matrices. Khan et al (2016) also verified the enhancement of thin film mechanical properties when fractionated bleached pulp fibers are reinforced into a biodegradable polymer (alginate) matrix.…”

Cellulosic Pulp Fiber as Reinforcement Materials in Seaweed-Based Film

et al. 2016

Composite materials made from renewable resources can minimize the environmental pollution. In this work, biocomposite films were produced using seaweed as matrix and empty fruit bunch (EFB) pulp fibers as reinforcement. Based on the results, the EFB pulp-seaweed composite films exhibited better mechanical properties than the seaweed film. It was also observed that 50% EFB pulp loading gave the highest tensile strength (81.4 MPa) and elongation at break (5.4%). This phenomenon was supported by SEM analysis, in which more fiber breakage than fiber pull-out was observed on the tensile fracture surface of composite film. Additionally, no agglomeration of the pulp fibers was observed. Instead, the pulp fibers were homogenously distributed throughout the film. In contrast, the contact angle of the seaweed-based films started to decrease once the pulp fibers were added. The decrease in the contact angle was attributed to the hydrophilic nature of the pulp fibers. Nevertheless, the contact angle values of all composite films were still comparatively high and thus, this would not affect their application as a packaging film.

“…After subtracting the cellulose and hemicellulose from the carbohydrate content of the 9 preparations, each group contained approximately 20% water-soluble polysaccharide in the algal pulp. The influence of water-soluble polysaccharides in the process of papermaking remains unclear; however, adding brown algal water-soluble polysaccharides to the wood pulp might increase the mechanical properties of the resulting paper [ 36 ].…”

A Comparison of Cooking Conditions of Rhizoclonium Pulp as a Substitute for Wood Pulp

The green macroalga Rhizoclonium was cooked with 5%, 10%, and 20% sodium hydroxide (NaOH) for 4 h (5-N, 10-N, and 20-N groups, respectively); with 5%, 10%, and 20% sodium sulfite (Na2SO3) for 4 h (5-NS, 10-NS, and 20-NS groups, respectively); and with 5%, 10%, and 20% NaOH for 2 h and 1% hydrogen peroxide (H2O2) for 2 h (5-NH, 10-NH, and 20-NH groups, respectively). The 5-NH handsheet showed the best mechanical properties; however, the 10-NH pulp was easier to separate than 5-NH during handsheet making, and 10-NH was more suitable for the industrial process. Thus, the 10-NH group showed the optimal production conditions with an optimal length/width ratio, crystallinity index (CI%), three-dimensional (3D) configuration, and mechanical strength. Substituting 20% 10-NH Rhizoclonium pulp with wood pulp had no significant effect on the mechanical properties of the 100% wood pulp handsheet. However, the fibers of the NS group were flatter and lost their 3D configuration, resulting in low mechanical strength. Overall, Rhizoclonium had its own optimal cooking condition, which was not the same as for wood pulp, and it has potential as a substitute for wood pulp in papermaking.

Ein Trend in der Zellstoff‐ und Papierindustrie ist die Nutzung von Nicht‐Holzpflanzen, z. B. von Einjahrespflanzen und Gräsern. Sie sollen Bäume als Rohstoffquelle für Zellstoff substituieren. Da sich die Zusammensetzung und die Fasereigenschaften unterscheiden, müssen diese bewertet werden. In dieser Machbarkeitsstudie wurden Zellstoff aus Hopfen, Hanf und Miscanthus extrahiert, die Ausbeuten und die Fasereigenschaften untersucht und mit verfügbaren Daten für Zellstoff aus Kiefern‐ und Fichtenholz (Northern Bleached Softwood Kraft) verglichen. Es zeigten sich sehr hohe Ausbeuten von bis zu 86,6 Ma.‐% für den Natural‐Pulping‐Aufschluss sowie eine niedrige Kappa‐Zahl von 3,5 für Miscanthus. Demnach wurde fast das gesamte Lignin entfernt. Damit bestätigt sich die hohe chemische Wirksamkeit der Aufschlüsse sowie das große Potenzial von Einjahrespflanzen und Gräsern.
