3.  Bio processing - great potential for industries
 The bulk part of textile production migrates to the
developing world, partially because of stricter
environmental regulations in the industrialized
countries. The developing world has the possibility to
create a unique competitive advantage by promoting
environmentally sustainable production process based
on Biotechnology
 Bamboo plant does not need any pesticides &
insecticides & fungicide to grow of plant so it’s called as
green plant.
Textiles made of bamboo fiber are eco-friendly.

5.  Bamboo is the general name used for a number of
perennial, woody-stemmed grasses
 They are a popular landscape plant because they grow
rapidly, are evergreens, and create a tropical or exotic
atmosphere.
 They are often marketed as alternative, fast-growing
privacy screens. Basically bamboo is a grass; it is the
world’s fastest growing ‘Woody Plant’.

6. Manufacturing process of
bamboo fibers
Mechanical
Chemical

7. Mechanical
Bamboo plant is crushed into a pulp
Natural enzymes are used to form a mushy substance
Fibers are combed out
Fibers are spun into yarn

9. Chemically
Bamboo leaves & trunk are extracted and crushed.
Crushed bamboo cellulose is soaked in a solution of 20% NaOH
at a temp at 20°C for 3 hours to form alkali cellulose.
Then pressed to remove any excess NaOH solution.
The alkali cellulose is crushed by a grinder and left to dry for 24
hours.
CS2 is added to the bamboo alkali cellulose to sulphurize the
compound and become jelly.

10. ……..Chemically
Remaining CS2 is removed by evaporation
Formation of cellulose sodium xanthogenate
A diluted solution of NaOH is added to the cellulose
sodium xanthogenate dissolving it to create a viscose
solution consisting of about 5% NaOH and 7% to 15%
bamboo fiber cellulose.
The viscose bamboo cellulose is forced through spinneret
nozzles into a large container of a diluted H2SO4 solution.
It hardens the viscose bamboo cellulose sodium
xanthogenate and reconverts it to cellulose bamboo fibers
which are spun into yarns to be woven.

13. Typical Layout of Wet Spinning Process
WEAVING
Bamboo fibers have some properties that are not feasible i.e. it is
sensitive to moisture regain and become weak as it moisture regain
increase. So during the whole process the suitable rate of moisture
regains is 8%-9%.
