Effect of acrylonitrile grafting treatment on various biofibers.

S. no.	Fibers used	Type of chemical treatment	Effects	Ref.
1	Pineapple leaf	Acrylonitrile grafting	Improvement in tensile strength by adding AN (acrylonitrile grafting). It has major effect on tensile strength.	[75, 102]
2	Oil palm	Acrylonitrile grafting	The treatment showed high strain rate and elastic modulus. But slight improvement in stiffness was absorbed. However at 40 wt% of fiber with 50°C exhibited higher moisture resistance compared to other treatments.	[153]
3	Agave Americana fibers	Acrylonitrile grafting	An increase in percentage of graft and decrease in the moisture resistance, in addition to improvement in thermal stability of fiber.	[156]
4	Sisal	Acrylonitrile grafting	The treatment showed enhanced tensile and flexural strength as compared to other treatments. Least degradability of fibers was observed.	[157]
5	Pineapple leaf	Acrylonitrile grafting	The treatment possesses lower grafting yield than unmodified fibers.	[158]
6	Cellulose polymer	Graft copolymerization	Improvement in physical, chemical, and thermal resistance.	[159]
