The low amounts of neutrals in jute fibers, particularly the low abundances offree and conjugated sterols, which have a high propensity to form pitch deposits,
would point to a low pitch deposition tendency of the lipophilics from jute

Jute (Corchorus capsularis) fibers
- High content of hollocellulose (and
-cellulose) and low content of ash,
appropriate raw material for pulp andpapermaking!
- Low lipid content, low content of neutrals,
in particular free and conjugated sterols,
low pitch deposition tendency!
- Low lignin content, with high S/G ratio, a
high abundance of -O-4 linkages and a
low content of condensed structures,
easily delignifiable!
Main Conclusions
Jute fiber is an excellent raw material for pulp and papermaking !
