  • Description: INVESTIGATIONS WERE MADE TO DETERMINE THE SUITABILITY OF FIVE Philippine hardwoods for use in several kinds of paper, including wrapping paper, corrugated container board, and newsprint paper. The particular hardwoods investigated were ilang-ilang (Canangium odoratum), manggasinoro (Shorea philippinensis), red lauan (Shorea negrosensis), tangile (Shorea polysperma), and white lauan (Pentacme contorta). Supplementary fibrous materials investigated as possible sources of long fiber included abaca or Manila hemp (Musa textilis), kenaf (Hibiscus cannabinis), and the softwood, benguet pine (Pinus insularis). The Philippine hardwoods, the plant materials, and the benguet pine all were readily pulped by the sulfate process. The hardwoods did not respond favorably to pulping by the neutral sulfite process. The tendency for the pulps and certain papers or boards to be deficient in tearing and folding strength due to the short fibers used can be practically offset by the addition of moderate quantities of pulps made from the long-fibered materials. Thus, the hardwoods were indicated to be suitable as the basic fiber source for a pulp and paper establishment for production of a variety of products. (Author)
