Mercerizing
Our chainless mercerising range is suitable for cold as well as hot mercerisation. This range yields the required lustre, colour affinity and appearance. The brilliant feel of the fabric after mercerisation in our machines meets customers’ requirements entirely.
The mercerising range consists of an impregnating zone, a stabilising zone and a lye recuperator. Novel wet-on-wet mercerisation with add-on application of caustic and total dimensional stability with unique stretching zone.
This is a process in which textiles (typically cotton) are treated with a caustic (NaOH) solution to improve properties such as fibre strength, shrinkage resistance, luster and dye affinity.
Mercerizing has become an important step in the textile pretreatment of cotton.
-
Diffusion compartment with grooved stainless steel rollers for swelling of cotton fabric
-
Rotary drum filter with circulation pump for caustic recovery
-
Longitudinal/lateral stretching zone for stretching fabric longitudinally and horizontally
-
Counter-current washing and pH control
-
Very limited contact with fabric to avoid width-shrinkage
-
Indirect heating system for hot mercerisation
-
Addition of caustic possible for wet fabric
-
Accelerated diffusion due to higher concentration gradient
-
Dimensionally stable fabric
-
Reduction of caustic volume
-
Drying process minimised for feed fabric
-
Less residual shrinkage

Significant savings in terms of chemicals, energy, water and time
-
Less polluting and more eco-friendly
Chainless Mercerizing
Chainless mercerize is equipped with :
- For wet on wet mercerizing, S Roll squeezer before impregnation, which results in lesser exchange of moisture with caustic and lesser consumption of caustic soda.
- Caustic soda circuit with mixing trough, pumps and heat exchanger.
- Impregnation compartment is with stainless steel modular concept.
- Driven bottom rollers for better fabric tension control and stretching in warp direction.
- After impregnation, S Roll squeezer to minimize caustic consumption.
