Studies on the Decay of Bamboo (<I>Dendrocalamus strictus</I>) during Outside Storage-I. Effect of Preservatives II. Effect on Pulping Qualities

Abstract

Bamboo is the main raw material used in the Pulp and Papar Industry in India. It is generally stored in onside locations for periods ranging from few weeks to a year. During storage it is estimated that about 20-25 percent of the raw material is deotroyed due to attack hy wood destroying organism in order to protect the bamboo from deterioration different preservations treatments were given to the baboo D. strietus which were stored for a peried of twelve months. Detailed chemical studies of the untreated and treated bamboos at the begianing and after storage periods of 4,8 and 12 momths were carried out. Mycological studies on the stored bamboos were also made during this period. The pulp yield and strength properties of the hand sheets prepared from stored bamboos Were also evaluated. The preservative treatment cut down the wood substance lossed by about 28-30 percent in a period of twelve months, while the pulp yietd losses were reduced by about 30 percent.
