Abstract

The delignification of horse grass (HG) was carried out using methanol and water (organosolv pulping); varying the cooking conditions at 30min, 60min and 90min with ratios: 1:1, 1:2 and 1:3, Methanol-water, cooked in autoclave at 1050C. The pulp obtained were selected and macerated in equal volume of glacial acetic acid (ethanoic acid) and hydrogen peroxide (1:1) at a temperature 1000C, to investigate the fiber length; fiber diameter; lumen with their derived indices and paper strength properties was determined according to TAPPI standard methods, T 494 om-96. The best fiber length of 3.21mm, tear index 31.43 mN.m2/g, tensile index 97.79Nm/g and bulk index 5.15 kPa.m2/g was obtained at 1:3 methanol: H2O at 105°C with cooking time of 60 min. Therefore, it was established that high quality papers of different grades can be produced from horse grass with acceptable strength properties using low concentration of methanol/water pulping with moderate time at boiling temperature. The research concluded that methanol-water was excellently good for pulping of horse grass fibers. The above results showed that horse grass is a good alternative sources of fibers to produce pulp and paper.
