3. • Fibers are extracted for textiles, brushes, plaiting or coarse weaving,
stuffing material, paper and specialty goods.
• Cotton, flax, ramie, and hemp are most often used for apparel or textile
fibers.
• Jute, cotton, hemp, abacá, sisal, New Zealand flax, and Mauritius hemp
are most often used for cordage.
• Istle, sisal, piassava (palm), and broomcorn (a Sorghum bicolor cultivar)
are most often used for brushes or braiding fibers.
• Kapok, cotton, Spanish moss, and jute are most often used for filling
fibers.
Fiber Extraction

6. RETTING
Fibres are extracted by the process of retting .
Retting is to immerse then fibre bundles in clear slow flowing water
in canals, rivulets, ponds or ditches.
Fibres come together to form stem and ribbon (outer skin ) of plant.
Consists of bundling stems together
Immersing them in low & runnng water .
However , in practice farmers immerse them in local bodies like
small ponds .

10.  Since fibres are contained in the bark or outer skin of stem so either
stems or outerskin called ribbons are retted .
If the stem is retted it is called stem retting.
But
If the ribbons are retted then it is called ribbon
retting .

11. Conditions for good retting
Important conditions for good retting are :
 Water should be non saline and clear .
 Volume of water should be enough to make fibre bundles float .
 When bundles are immersed they should not touch the
bottom.
 Same Retting tank or ditch should not be used.

14. STRIPPING
 The process of removing fibres from the stalk after completion of
retting.
 To judge the right time for striping the fibers from the retted plants of
the ponds or cannels where the plants have been kept for retting.
 Washing and drying of the fibers should be done as quickly as possible.
 Fibres can be removed by any one of following methods :
 Single plants are taken and their fibres are taken off .
 Handful of stalks are taken off, breaking it in a to & fro motion in
water.

15. The bundles of stems are removed from water, allowed to
drain off and then each stem stripped separately. Fibers are
made up into handful and then
washed.
Stripping by hand:

17.  The worker stands in water. He takes some stems in his left hand and beats
the roads of the steams cloth a wooden mallet.
 When the root ends are sufficiently crushed, they are broken off.
 Loose fibers are then drawn to permit easy separation from the rest of the
stems.
 The stripped of fibers are then
washed.

25. Bagasse
• Bagasse is the fibrous material that
remains after sugarcane are crushed to
exact their juice from sugarcane. It is
dry pulp residue left after the
extraction of juice from sugarcane
• Also known as Sugarcane fibre

CHEMICAL COMPONENTS OF SUGARCANE FIBRE

28.  At first juice are extract from the
sugarcane.
 After juice extraction the bagasse are
collected for fibre extraction.
 The soft core part pith is removed from the
bagasse manually to get outer hard ring
 The samples are then taken into hot
water treatment
 The samples are then dried in the
sunlight
 Then samples are chemically treated
 After chemicals treatment the fibres are
separated .
