Printability Characteristics of Paper Made From a Japanese Knotweed

Abstract

Cereal straw and bagasse are presently the leading non-wood plants used in production of paper, though many fast-growing perennial plants have been studied for their suitability for paper manufacturing, too. In the present study the use of Japanese knotweed, as one of the most invasive alien plant species in Slovenia, as alternative raw material for papermaking is demonstreted. Paper was made of 55% Japanese knotweed and sulfate cellulose produced from 60% eucalyptus and 40% conifer fiber. The paper with the basic weight of 90 g/m 2 was manufactured on the pilot paper machine at the Pulp and Paper Institute. Among printability characteristics paper brightness, colour, yellowness, roughness, air permeability, specular gloss, print penetration, picking, and print unevenness were determined. The preliminary research has shown, that Japanese knotweed, as a cheap local raw material, could be used in paper making industry, though the fiber processing and paper making process must be improved in order to obtain good printability.

The X-Ray Diffraction Pattern of the Ash Content on Ignition at 900 ˚C of a Copy Paper Sample and its Mechanical and Optical Properties

“…Also, the roughness Bendtsen [3] of the paper is primordial for the absorption and the spreading of inks, and also for determining the amount of coating. Relation could be considered as to the scale of roughness to properties of paper such as gloss and pick resistance [4,5]. The effect of the pH value could be examined as to its influence on the optical and morphological properties of a copy paper sample.…”

Fibers Obtained from Invasive Alien Plant Species as a Base Material for Paper Production

“…Remote sensing, as satellites are called, is already being used in forestry, agriculture, and ecology because it is a less expensive technique compared to field reconnaissance methods (Figure 1). Preliminary research by Lavrič [6] has shown that the invasive Japanese knotweed could be used as a cheap local raw material in the paper industry, but in order to achieve good printability properties of the paper, mainly the fiber processing needs to be improved. Kim et al, isolated cellulose nanofibers from pulps of a tall goldenrod (Solidago altissima L.), an invasive plant in Korea, using electron beam irradiation [7].…”

“…DC., and Hibiscus cannabinus L., and a reed species were investigated in the laboratory for their properties for pulp and paper production, and the results suggested that the plant species studied would be ideal sources of raw material for the pulp and paper industry. In the project APPLAUSE, seven IAPS Preliminary research by Lavrič [6] has shown that the invasive Japanese knotweed could be used as a cheap local raw material in the paper industry, but in order to achieve good printability properties of the paper, mainly the fiber processing needs to be improved.

A comparative fiber morphological analysis of major agricultural residues (used or investigated) as feedstock in the pulp and paper industry

“…Various non-wood plant agricultural sources have already been considered as potential pulp and paper feedstocks in the past (Ogbonnaya et al 1997;Gonzalo et al 2017;Saeed et al 2017a;Gülsoy and Şimşir 2018;Lavrič et al 2018). In addition, energy crops, and their residues, including Miscanthus spp.…”
