Abstract
Scouring is a cleaning process for renewing natural and actiuired impurities
of fibers. Common industrial practices involve use of sodium hydroxide
to remove non - celltilosic materials. In (his process, the individual non -
cellulosic components other than natural colouring matters are converted
into solute compounds are removed in subsequent washing. This traditional
scouring process consumes large quantities of energ)' and water and is not
ecofriendly. High level of pH and temperature used in this process that damages
the fiber due to non - specific attack of alkali especially when performed
in the presence of oxygen, it also results in loss in strength of the fiber. Hence,
there was demand for scouring process carried out using mild conditions. It
led to the development of substrate specific, low water consuming and environment
friendly process, namely enzymatic scouring. Textile wet processing is
one of the largest and oldest industries world wide, responsible for substantial
resource consumption and pollution especially in terms of water.
