Lignin
in jute makes the fibre resistant to easy microbial attacks, and provides better strength
alongwith hardness and brittleness.
Chemical
composition varies with plant age, retting, etc.
Lignin
has advantages in some technical textile applications (like geo-textiles applications )
and disadvantage of lignin can be reduced in value added home textiles applications by
chemical and biological routes.
