2. INTRODUCTION
• Sisal Fiber is one of the most widely used natural fiber and is very easily
cultivated. It is obtain from sisal plant.Acoarse and strong fibre,sisal is being
increasingly used in composite materials for cars, furniture and construction as
well as in plastics and paper products.
• Sisal fiber is fully biodegradable, green composites were fabricated with soy
protein resin modified with gelatin. Sisal fiber
,modified soy protein resins, and
composites were characterized for their mechanical and thermal properties. It
is highly renewable resource of energy. Sisal fiber is exceptionally durable and a
low maintenance with minimal wear and tear
.
4. ORIGIN A N D HISTORY OF SISAL FIBER
• Sisal is the coarsest of the ‘hard’ vegetable fibers.There are many varieties of the Agave
plantthroughoutthe tropicalandsub-tropicalworld,especiallyin the CentralAmerican
region.TheEastAfricansisal plantwas originated in theYucatanin 1983.A little later,sisal
bulbils sent from Kew Gardens were planted in Kenya.After adifficult start, sisal
productionin EastAfrica prospered andby the 1960sTanzaniaproduction alonetotaled
some 230,000 tons. Production in East Africa has contracted materially over the past
three decades in response to the continuing movement in end products awayfrom the
low valueagriculturaltwinemarket into considerably highervaluemore specializedend
products, such as carpets, wire rope cores, dartboards, specialty pulps, plaster
reinforcementandhandicrafts.Now Brazil dominatesthe world marketin terms of sisal
production.

7. CHEMICAL COMPOSITION OF SISAL
FIBER
• The components of sisal fiber (% by weight):
• Cellulose 55-65
• Hemi-cellulose 10-15
• Pectin 2-4
• Lignin 10-20
• Water soluble materials 1-4
• Fat and wax 0.15-0.3
• Ash 0.7-1.5
8. GRADATION OF SISAL FIBER
• Sisal is used and graded by the industries in three grades.
• The lower grade: High content of cellulose and
hemicelluloses. Used in paper industry.
• The medium grade: Used in the cordage industry for
making: ropes, baler and twine. Ropes and twines used in
marine, agricultural, and general industrialuse.
• The higher grade: Fiber after treatment is converted into
yarns and used by the carpet industry.
9. CHEMICAL TREATMENTS O N SISAL FIBER
• Treatment with sodium hydroxide: Sodium hydroxide does
not affectbut it dissolves and removes some of the non-
cellulosic materials such as hemi-cellulose, pectin and
water soluble substances.
• Resistance to sulphuric acid:Ifsisal fibers are immersed in
sulphuric acid,it will decompose.
• Resistance to water: Shows good water resistance.
Resistance of sisal fiber to seawater is higher than that to
fresh water
.
10. APPLICATIONS OF SISAL
• The short sisal fiber, with its features of softness, high-flexibility, high
friction resisting, acid resisting and alkali resisting, it is an excellent
material of High-quality sofa, Wadding mat Pulp Constructing
materials
• The plants can be also used as an effective hedge to protect crops
and land from predators, and the extensive root system helps to
reduce soil erosion in arid areas.
• Other sisal materials include Rope Sisal core for steel wire rope,
Yarn and twine, Sisal cloth Polishing , buff Carpet Pulp
,Constructing materials and doormats
