“…Therefore, the pulp and paper industry, which produces about 40% of its products directly from wood, takes action to obtain fibres from forest plantations (Tarnawski 2006;Christersson 2010), producing papers and paperboards with a growing proportion of waste paper (Miranda et al 2010) and mechanical pulps (Ford and Sharman 1996) and seeking possibilities to increase the yield of kraft pulps from wood (Bach and Fiehn 1972;Hart and Rudie 2014). Another possibility to reduce the dependence of the industry on wood is to use non-wood plant fibrous raw materials (NPFRMs) to produce papermaking pulps (Guadalix et al 1996;Paavilainen 1998;Vargas et al 2012;Danielewicz et al 2015).…”

The papermaking potential of bleached kraft pulps made from hemp stalks, hemp woody-core and hemp bast fibres was studied and compared with that of bleached birch pulp and pine kraft pulp. It has been shown that among the pulps from these raw materials, hemp stalk pulp has the most useful properties for papermaking. The disadvantages of hemp woody-core pulp and hemp bast fibre pulp as papermaking intermediates proved to be low tear resistance and low tensile strength, respectively. Results indicate that the main reasons for the low tensile strength of hemp bast fibre pulp are the low susceptibility of their fibres for internal fibrillation and low hemicellulose content. The technology used in this work for the processing of hemp bast fibres into papermaking pulp made it possible to obtain pulp with high a-cellulose content from this fibrous raw material with a high yield in a much simpler way than when such pulps are obtained from wood.

“…In agreement with this, tensile strength index for OFI waste pulp (36.0±5.0 Nm/g) is low in comparison with that of pine (76.1 Nm/g) and poplar (40.40 Nm/g) pulps. However, it is in the same range of pulp derived from non-wood fibers like sugarcane bagasse (38.2 Nm/g), rice straw (41.7 Nm/g) and sunflower stalks (43.64 Nm/g) (Khristova et al, 2006;Fišerová and Gigac, 2011;Sarwar Jahan et al, 2012;Mazhari Mousavi et al, 2013;Danielewicz et al, 2015).…”

The papermaking potential of Opuntia ficus-indica (OFI) waste fibers was studied in this research. Alpha cellulose, lignin, hollocellulose, ethanol/benzene extractives and ash content were determined as 53.7±0.1%, 2.4±0.3%, 61.6±5.7%, 7.1±0.3% and 26.4±0.1%, respectively. The average fiber length, width, lumen and cell wall thickenss were found to be 1.1±0.3 mm, 18.8±6.1µm, 12.1±5.4 µm, 4.3±1.0 µm. Soda pulping was conducted using 20 and 28% sodium hydroxide, cooking temperatures of 160 and 175 °C, cooking times of 60 and 120 min, and liquor- to fiber ratio of 9:1. Soda pulping with 28% sodium hydroxide, 175 °C and 120 min showed a lower Kappa number of 29.60±1.7 and a total yield of 32.2±1.6 %. In general, tensile strength index (36.0±5.0 Nm/g), stretch (1.7±0.3%), breaking length (3.7±0.5 km), burst index (3.2±0.4 KPa.m2/g), tear index (7.3±0.0 mN.m2/g), folding endurance (166 times) and porosity (> 120 s) of OFI pulp were comparable with wood and non-wood pulps.

“…The mechanical beating of the mixed beech and eucalyptus pulp (65% to 35% by w/w, respectively) was performed in a laboratory Jokro mill at a pulp consistency of 6 wt. % in time evaluated on the basis of our previous studies (Danielewicz et al 2015) in accordance with the PN-EN standard 25264-3 (1999). Jokro mill, similar to PFI mill, consists of several refining grooved rolls placed in containers and rotating at the same speed reaching 150 rpm.…”

Effects of cellulase enzymatic treatment followed by mechanical beating were evaluated relative to the properties of cellulase-derived tissue pulps and handsheets. When different cellulase concentrations (0.0012 FPU/g, 0.0018 FPU/g, and 0.0024 FPU/g) of oven dried pulp (a 65/35 w/w ratio of beech to eucalyptus) were used for tissue production, a slight deterioration of the morphological characteristics was observed. Thus, a possibility of controlling the changes in the degree of polymerization of cellulose, as well as the fiber properties (in particular the length and coarseness) appeared. With an increased treatment time and enzyme concentration, these effects increased. The enzyme activity did not affect the apparent density of the paper, but the porosity drastically increased. The zero-span strength of the enzymatically treated pulps decreased with an increase in treatment time and amount of cellulase. However, mechanical beating improved the bonding between the cellulase fibers, which helped prevent the eventual decrease in mechanical properties of the handsheets. With the use of cellulase, the proposed moderate changes to fiber structure were achieved, giving the possibility of predicting and controlling the properties of tissue paper.
