Properties of areca nut leaf sheath fiber
India is the most elevated maker of areca nut on the planet – the nation represents more than 50% of world creation. The leaf sheath of the areca nut comprises numerous constituent materials like cellulose, hemicellulose, lignin, and gelatin and so forth Long-staple strands can be separated from the areca nut leaf sheath by soluble base treatment. A report.
Areca catechu or areca palm is a type of palm family. It is usually filled in tropical areas. Areca nut is a significant money crop that is filled in India, China, Malaysia, Taiwan, and other Asian nations predominantly for their seeds-nuts. India is the most elevated maker of areca nut on the planet – represents more than 50% of world creation. It is assessed that consistently India produces l000 million areca nut leaf sheaths weighing around 2.33 lakh tons. The leaf sheath of the areca palm is a hard biodegradable stringy material. It is an effectively accessible, low-estimated, and inexhaustible asset of lignocellulosic rural biomass. The leaf sheath comprises numerous constituent materials like cellulose, hemicellulose, lignin, and gelatin, and so on Long-staple strands can be extricated from areca nut leaf sheath by salt treatment.
Fiber Properties
Compound synthesis of fiber
Being lignocellulosic fiber, areca nut leaf sheath fiber contains three essential compound parts, that is, cellulose, hemicellulose, and lignin. It is seen that areca nut leaf sheath fiber contains 56.8 percent cellulose, 22.4 percent hemicellulose, and 6.3 percent lignin, individually.
Crystallinity record and microfibrillar point
It is shown that the strength and beginning modulus of lignocellulosic strands rely upon the crystallinity list and microfibril point. Higher crystallinity record and lower microfibril point increment the mechanical properties of cellulosic filaments. It is seen that the crystallinity record and microfibrillar point of areca nut leaf sheath fiber are 56.5 percent and 35.2o, separately.
Dampness content of fiber
Being regular fiber areca nut leaf sheath fiber contains hydrophilic – OH bunch in their particles. The water particles present in air draw into hydrophilic gatherings of fiber and structure hydrogen bonds. It is seen that the dampness content of areca nut leaf sheath fiber is 11.9 percent.
Fiber length and width:
Length and width of fiber is a significant boundary to control the nature of the fiber. Use region, preparing execution and material properties, and so on are influenced by the length and width of fiber. Areca nut leaf sheath length is around 1-1.5m long. The singular filaments lie consistently along the length of the sheath. The separated fiber length relies upon the slashed length of areca nut leaf sheath during fiber extraction measure. The greatest fiber length will be a similar length to the leaf sheath. It is seen that the fiber breadth changes from 14 to 392 µm with a normal distance across 55 µm.
Group and single fiber strength
One of the main properties of fiber is the ductile property. Elastic properties of yarns and textures rely upon both complex fiber game plans inside the yarn and texture structure, and on the ductile properties of strands. The group strength of areca nut leaf sheath fiber is 18.8 g/tex at 5 cm check length. The single fiber elasticity, introductory modulus, and lengthening at break are 400 MPa, 11.8 GPa, and 8 percent, separately.
