Bio scouring vs Alkaline scouring | 12 Key Differences!
In the textile industry, a huge amount of alkali is used every day for scouring purpose. But the unspecific use of these chemicals not only attacks the impurities but also attacks the cellulose of the fibers. This leads to a certain loss of strength properties. Again, a huge load of chemicals in the effluent water adds loads to the environment. The effluent water has high TDS, BOD, COD values and affects the environment tremendously. Bio-scouring is a smart and eco-friendly solution to all of these problems.
12 Difference Between Bio scouring vs Alkaline scouring
Bio-scouring is done with enzymes
Scouring is done with alkali solution
Provides smoother surface profile
Cellulose with complete removal of impurities
Cellulose with complete removal of impurities and partial cellulose
No need of alkali neutralization
Requires alkali neutralization
Less washing cycle
More washing cycle
Less amount of TDS, BOD, COD
More TDS, BOD, COD
No loss of fabric strength if controlled bio-scouring is carried out
Loss of fabric strength
Costlier than bio-scouring
Carried out at moderate temperature like 55°C
Carried out at boil temperature
No added chemicals are required
Added chemicals are required
Not suitable for removing seed coat fragments and motes and inability to remove waxes adequately
Seed coat fragment, motes, waxes everything removes completely
