II - Date palm rachis as a source of cellulose fibres for papermaking applications

II - 1 - Objective

Important quantities of date palm rachis accumulated every year in Tunisia. The rational valorisation of these available renewable resources fits very well with the recent sustainable approach, established nowadays. This work aims at ascertaining the chemical composition of this agricultural residue and testing the cooking conditions leading to pulp production for papermaking. The resulting pulps were then refined using a PFI mill refiner at 0, 500, 1500 and 3000 revolutions. The disintegrated and refined pulps were then screened through a sieve of 0.15 mm mesh size and used to produce conventional handsheets. The resulting samples were fully characterised in terms of physical properties, according to commonly used standards. The physical properties of the prepared materials were close to those displayed by other common papermaking furnishes. The obtained pulps and papers combine good drainability with excellent mechanical properties. Thus, date palm rachis can be considered as potential source of fibres for papermaking application.
