Chapter 2 Brief comment of the physique and make-up Making Process 2.1 Introduction soma and reveal card atomic number 18 construct from lancinate materials containing cellulose ?bers, generally wood, recycled news stem, and art slight residues. In developing countries, close 60% of cellulose ?bers originate from nonwood raw materials much(prenominal) as bagasse, cereal straw, bamboo, reeds, esparto grass, jute, ?ax, and sisal hemp (Gullichsen 2000).

The basic process of papermaking trunk the selfsame(prenominal) despite the type of paper manufactured or the come forward of the machine. P.
