The
pulp and paper industrybasically comprise of companies that use wood as
raw material and produce pulp, paper, board and other allied
cellulose-based products.Papermaking, technical textiles and special
belt making are major industries. These are the industries that feed the
other industries to produce capital and other goods for domestic use.
Pulp
is a lignocellulose fibrous material produced by separating cellulose
fibres from wood, fibre crops or waste paper. Wood serves as about 90 %
of the raw material for pulp industry with the remaining originating
fromother plants. Pulp is most commonly used as raw material in
papermaking, but it is utilised by the textiles, food, pharmaceutical
and many other industries too.
Paper-makingcan be traced back to China about 105 BC, when paper was
made using mulberry and other fibrescombining them with fishnets, old
rags, and hemp waste. Modern papermaking industry has become much more
organised and scientific with several sections, roughly corresponding to
the processes traditionally involved in making paper. Pulp is refined
and mixed in water with other additives to make a pulp slurry. The pulp
slurry is distributedon a moving continuous screen and water is drained from the slurry. The wet paper sheet is compressed, dried and rolled.
