BIO-SCOURING
Introduction
 Bioscouring is a process by which alkaline stable
pectinase is used to remove pectin and waxes
selectively from the cotton fibre.
 Pectinase, as the name suggests, hydrolyses pectins
present in cotton as a non-cellulosic impurity.
Types of enzymes that are used for bio-
scouring process:
 Pectinase:-Pectinases are used for the removal
pectic substances from cotton.
 Lipases :- They are used for the removal of
natural fatty substances from cotton
 proteases:- proteases are enzymes that catalyse the
hydrolysis of proteins.
Mechanism of bio-scouring
The following two stages mechanisms are involved in bio-
scouring
Stage :1
 Removal of wax ( a major part being fatty acids, alcohols and
esters) is the critical factor for improved wettability. Pectin
functions as a ‘glue’ binding wax to the fibre. Pectin
removal does not by itself result in wax removal or improved
wettability but it renders wax extractable or emulsifiable.
 Presence of Ca++ slows down the removal pectin and fatty
acid, so a sequestrate should, if compatible, be applied with
the enzyme – otherwise after the enzyme reaction.
continued
Stage 2:
 2/3 or more of the pectin must be dissolved in
order to be able to emulsify enough wax for a
good wettability for dyeing.
 Emulsification is strongly enhanced at
temperatures above the wax melting point,
i.e. >70°C
Bio-Scouring Process:
Important process parameters
 pH andTemperature
 Wetteners
 Emulsifiers
 Pectinase enzyme
Recipe Formulation:
Enzymatic scouring was carried out by the following
recipe-
 Enzyme : .............................................3 g/L or 0.5%
 Sequestering agent : ...........................1 g/L
 Wetting agent : ...................................2 g/L
 Emulsifier ………………………………………. 0.5-1.5 g/l
 Temperature : .....................................60oC
 Time : ................................................30 min
 M: L : ................................................1:10
 PH : ...................................................6-9
Here,
1. Water,wetting agent, PH buffer and fabric;
2. Enzyme (pectinase);
3. Emulsifier.

 Blend of Enzymes-
Pectinase + Protease
 Removes Pectin,

 Sodium Hydroxide
 Remove Pectin,

Results of Bio andAlkaline scouring
Bio-scouring
 Soft Handle
 cellulose with complete
removal of Impurities
 No core Alkali
neutralization, thus less
washing cycle
 LessTDS, COD, BOD
Alkaline-scouring
 Harshness
 cellulose with complete
removal of Impurities
and partial Callulose
 Required core alkali
neutralization, thus
more washing cycle
 More TDS, COD, BOD
Cost
Bio-scouring
 Direct cost is more
 but Overall cost is less
(Grey to finished)
Alkaline-scouring
 Direct cost is less
 but Overall cost is
more (Grey to finished)
.
Examples of Bio-Scouring and Alkaline Scouring
Advantages of Bio-scouring
 Save energy
 Save cost
 Water saving
 Temperature saving
 Time saving
 Smoother surface profile(Fully retain cellulose structure)
 Lesser weight loss
 Lesser costs of auxiliaries
 Mild application condition
 Environmental benefits
 Reduces effluent treatment process/ ETP cost
Disadvantage of bio-scouring
 Inability of removing of cotton fiber waxes.
 Enzyme activity can, however, be reduced or even
completely destroyed (denatured) by high
temperatures, extremes of pH and high concentrations
of electrolytes that destroy their three-dimensional
structures. Heavy metal ions and oxidizing and
reducing agents also deactivate the enzymes.
 The degree of whiteness is often less and the process is
not suitable for removing seed-coat fragments and
mote adequately.
Summary
 Though the conventional scouring process is
extremely using now-a-days, it has great bad effect
on environment.
 Many of the developed countries are avoiding the
convention-al scouring process replacing enzymatic,
ecofriendly, scouring processes.
 Bioscouring is an eco-friendly scouring process it
has great future.
 The new enzymatic procedure is corresponding with
a significant role in minimising the de-mand of
energy, water, chemicals, time and costs.
Thank you

  • 3. Introduction  Bioscouring is a process by which alkaline stable pectinase is used to remove pectin and waxes selectively from the cotton fibre.  Pectinase, as the name suggests, hydrolyses pectins present in cotton as a non-cellulosic impurity.
  • 4. Types of enzymes that are used for bio- scouring process:  Pectinase:-Pectinases are used for the removal pectic substances from cotton.  Lipases :- They are used for the removal of natural fatty substances from cotton  proteases:- proteases are enzymes that catalyse the hydrolysis of proteins.
  • 5. Mechanism of bio-scouring The following two stages mechanisms are involved in bio- scouring Stage :1  Removal of wax ( a major part being fatty acids, alcohols and esters) is the critical factor for improved wettability. Pectin functions as a ‘glue’ binding wax to the fibre. Pectin removal does not by itself result in wax removal or improved wettability but it renders wax extractable or emulsifiable.  Presence of Ca++ slows down the removal pectin and fatty acid, so a sequestrate should, if compatible, be applied with the enzyme – otherwise after the enzyme reaction.
  • 6. continued Stage 2:  2/3 or more of the pectin must be dissolved in order to be able to emulsify enough wax for a good wettability for dyeing.  Emulsification is strongly enhanced at temperatures above the wax melting point, i.e. >70°C

  • 11. Results of Bio andAlkaline scouring Bio-scouring  Soft Handle  cellulose with complete removal of Impurities  No core Alkali neutralization, thus less washing cycle  LessTDS, COD, BOD Alkaline-scouring  Harshness  cellulose with complete removal of Impurities and partial Callulose  Required core alkali neutralization, thus more washing cycle  More TDS, COD, BOD

  • 14. Advantages of Bio-scouring  Save energy  Save cost  Water saving  Temperature saving  Time saving  Smoother surface profile(Fully retain cellulose structure)  Lesser weight loss  Lesser costs of auxiliaries  Mild application condition  Environmental benefits  Reduces effluent treatment process/ ETP cost
  • 15. Disadvantage of bio-scouring  Inability of removing of cotton fiber waxes.  Enzyme activity can, however, be reduced or even completely destroyed (denatured) by high temperatures, extremes of pH and high concentrations of electrolytes that destroy their three-dimensional structures. Heavy metal ions and oxidizing and reducing agents also deactivate the enzymes.  The degree of whiteness is often less and the process is not suitable for removing seed-coat fragments and mote adequately.

Summary  Though the conventional scouring process is extremely using now-a-days, it has great bad effect on environment.  Many of the developed countries are avoiding the convention-al scouring process replacing enzymatic, ecofriendly, scouring processes.  Bioscouring is an eco-friendly scouring process it has great future.  The new enzymatic procedure is corresponding with a significant role in minimising the de-mand of energy, water, chemicals, time and costs.
