Sisal fibre


Sisal is an important leaf fibre in terms of its quality and applications It is obtained from the plant Agave Sisalana. Sisal is a xerophylic crop and is grown under wide range of agroclimatic and adoptic conditions except in waterlogged and ill drained soils.
The plant grows in a moist climate with a dry season and rocky soil. The countries, where sisal grows are.

USA, Florida, Bahamans, East Africa, Brazil, Indonesia and Phillipine3 Sis 9 The agaves have rosettes. of fleshy leaves, usually Long.  And narrow which grow out from a centre butt, as the leaves mature, they gradually spread out horizontally. 
The leaves are dark green, 1:0- 2,0 meter long, 10 20 cm wide at the base and 12-20 cm wide at the widest part  The sisal leaves gradually tapered to a sharp point. The fibres placed longitudinally in the leaves and are most abĂșndant hear the leaf surface 


Planting is done at the beginning of the rainy season. As the plants are become larger, harvesting is done by cutting the outer leaves. The fibre is removed by scrapping away the pulp material by a process, known as decortications'.

In the decortications process, the leaves are-fed through sets of fluted crushing rollers. The crushed leaves are held firmly at their centers and both ends passed between pairs of metal' drums, mounted with blades. 
The blades help to remove the pulp by scrapping. In a similar manner, centers are scrapped: The fibre strands are washed and dried by air or by any other means.


The fiber is coarse and strong. So it is used for making ropes, sail cloth, sacks and carpets. Sisal rope is. Extensively used in ship building industry, marine vessels and steamers as it is resistant to saline waters. It’s also used as a composite for floor coverings.
