“…Runkle ratio of 0.548 is almost equal to that of a cotton stalk (0.54) and less than that of wheat straw (0.83) and Rye straw (2.19) (Kasmani & Samariha, 2011). From this point of view, the fibers are suitable for papermaking.…”

This work investigates microwave soda pulping of the banana pseudo stem (Musa Cavendish), and process parameter optimization, morphological, chemical, and FTIR analysis. Response surface methodology, Box–Behnken designs were applied to investigate and find optimal microwave-assisted Soda pulping of the banana pseudo stem was carried out under different conditions. The influence of soda concentration (10, 12.5, and 15%), cooking temperature, (130,140, and 150 °C), and cooking time (15, 25, and 35 minutes) on the pulp yield and kappa number are studied. The optimal pulping (Active alkali 12.5%, at 140 °C for 25 minutes) of pulp yields about 37.2%, and a kappa number of 20.3% is obtained. The pulp was then made into 60 g/m 2 laboratory scale papers and their mechanical and surface properties were assessed. The results revealed that tensile index, tearing index, smoothness, and porosity was 79 Nm/g,19.1 mN.m 2 /g, 500-530µm, and 50 sec/100ml air respectively. The morphological analysis showed that the banana pseudo stem has a long fiber length (1750μm), tinny cell wall thickness (9.7μm), large lumen diameter (22.15μm), and thick fiber width (35.361μm) compared to hardwoods, agricultural residues, and bagasse. The chemical analysis revealed that the banana pseudo stem chemical composition includes cellulose (44.93%), hemicellulose (23.37 %), lignin (11.1%), ash (8.1%), and extractives (10.8%) were determined. This study indicates that high mechanical strength and good surface properties paper can be produced from banana pseudo stem pulp.

“…14 Also, the findings indicated that the surface of nanoclay coated paper was uniform and smooth, due to the high specific surface area of the nanoclay and the plate-like shape of its particles. 14 This study aimed to assess the mechanical and optical properties of printing papers treated by coating formulations comprising a nanoclay mineral and latex.…”

“…Furthermore, the addition of higher amounts of latex reduced porosity and therefore caused light scattering. [13][14] Previous investigations of the mechanical properties of coated paper indicated that, except stiffness, there are no significant changes in comparison with the control samples. 14 Also, the findings indicated that the surface of nanoclay coated paper was uniform and smooth, due to the high specific surface area of the nanoclay and the plate-like shape of its particles.…”

The present study aimed to improve the surface features of mechanical printing paper manufactured by the Mazandaran Wood and Paper Company. Inorganic materials, including nanoclay (in 6 different amounts) were used in different weight percentages of latex and applied by the blade coating method. Structural studies, such as SEM and XRD, were performed, and the mechanical and optical properties of the paper samples were evaluated. Scanning electron microscopy showed that the coverage achieved with the method used was relatively good. X-ray diffraction analysis indicated that an intercalation structure was formed. Moreover, the results of the mechanical tests showed that the enhancement of the nanoclay amount up to 25% can increase the air resistance, opacity and yellowness of the samples by 423.6, 4.1 and 59.5%, respectively, while decreasing their tensile strength, tear resistance, burst strength, stiffness, softness and brightness by 12.2, 12, 5.5, 6.5, 2.2 and 13.4%, respectively, in comparison with the values recorded for the control samples.
