Abstract:
To produce hydrophobic handmade paper
internal material rosin along with external additive
(MCC suspension), internal additive(wax emulsion)
and reinforcement were used. Optimum result was
obtained when rosin along with alum was used as
internal additive during pulp preparation and MCC
in the form of suspension was applied as external
additive. The hydrophobicity was increased by
92.46% due to rosin-alum treatment and
application of MCC suspension as external
additive. It was also observed that application of
wax along with rosin hampered/hindered the
hydrophobicity.
