Summary & Conclusions
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
Bamboo plant does not need any pesticides &
insecticides & fungicide to grow of plant so it’s called as
Textiles made of bamboo fiber are eco-friendly.
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
Manufacturing process of
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
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
CS2 is added to the bamboo alkali cellulose to sulphurize the
compound and become jelly.
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.

Typical Layout of Wet Spinning Process
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%.

According to results of XRD, although the crystalline
structure of the bamboo fiber belongs to cellulose I, it is
not the same as those of flax, cotton and ramie
XRD Graphs of the Fibers: Bamboo Fiber, Flax, Ramie and Jute
In the angle of diffraction peaks, quite similar to that of wood, which
shows overlapping of the diffraction peaks at (101) and (101) lattice plane.
It may be because of a high percentage of amorphous hemi cellulose and
lignin in the bamboo fiber. In addition, the degree of crystallinity of the
bamboo fibers is lower than those of the flax and cotton, and similar to
that of jute.
The low degree of crystallinity (52.54%) for the bamboo fiber may be due
to lot of substances grown with cellulose resultantly disturbing the
formation of the cellulose crystalline structure during the growth of
bamboo and about 20% of lignin and hemi cellulose residuals in fiber
will effect testing results to some extent

Degree of polymerization (DP)
DP of the bamboo fiber is close to that of the jute fiber, but lower than those of
flax and ramie, and far lower than that of cotton. The lower DP would usually
lead to lower tenacity for the fibers.
The DP of cellulose in fiber also is dependent on its surroundings. Higher the
lignin content is in the plant, the lower the DP of cellulose may be because of
disturbance created by the non-cellulose substances during polymerization,
this can be proved by the group of weak cellulose characteristic absorption
peaks at the wave numbers of 1032–1158cm–1 in the infrared spectrum of the
bamboo fiber (figure-10), also, by fibre size

Comparison of the results between natural
wet processing & conventional wet processing
of bamboo fabric
Main object is to produced 100% eco-friendly
bamboo fabric ---- NO hazards chemicals.
Save energy & eliminate harmful effect of
effluent to preserve the green status of earth.
Used of renewable raw materials
Literature surveyed based on green status of bamboo textile.
Manufacturing of bamboo fiber
Conventional process of bamboo textile & it’s involves hazard
Development of areas of bamboo fiber processing
Green wet processing of textiles.
Bamboo processing presently is not eco-friendly
We survey the eco-friendly process & also various enzymes to eliminate
sodium hydroxide with enzymes.
We survey the three natural dye which produced some herbal properties
on bamboo textile.
We survey natural finishing agent ALOE VERA which impart the
special antimicrobial properties on bamboo textile.
Out come of Literature review
oxidative bleaching are carried out using hydrogen peroxide in
Enzymes is a specialized protein produced within an organism
which is capable of catalyzing specific chemical reaction i.e.
hydrolysis, oxidation, reduction, etc.
Factors affecting enzyme activity are effect of temperature, Effect
of pH, Effect of activators, Redox potential,
In the present study hemicellulase, cellulase & pectinase enzymes
are used to process of eco-friendly pretreatment of bamboo fabric.
Pectinases capable of hydrolyzing pectinic substances are
generally enzyme complexes containing esterases and
depolymerases with random or terminal activities.
