Comparative study on Pulping characteristics of Carpinus betulus and Parotia oersica woods

In this investigation some anatomical, chemical and pulping suitability of two Iranian hardwood species which predominate in the Caspian forests were examined. The species are carpinus betulus (Hornbeam) and parotia persica (Ironwood).The results of this study revealed that:The average fiber length...

Thus, it may be concluded that for production of wrapping paper from carpinus betulus and parotia percica, using active alkali of 14% might give better quality paper and for production of printing paper from these two species active alkali of 20 percent might be desirable.Abdolrahman HosseinzadehAbbas Fakhryan roghaniAmir NourbakhshFardad GolbabaeiRegional Information Center for Science and Technology (RICeST)articleCarpinus betulusParotia oersicaanatomicalchemical and pulping suitabilityForestrySD1-669.5FAتحقیقات علوم چوب و کاغذ ایران, Vol 5, Iss 9- شماره 225, Pp 1-33 (2000)
