Bleaching of cotton

Bleaching process available for woven fabric and terry towel

Grinp developed a breakthrough process for the waterless bleaching of cotton.

The process allows to save water, save chemicals, save energy, save space and save costs.

Grinp industrial waterless bleaching process starts from greige fabric and combines several technological innovations.

The output of the process is wet bleached cotton fabric or towel, produced using just 2-4 litres per kg of cotton!

Compared to traditional methods, Grinp Bleaching process allows to save more than 70% of water and energy.

Grinp waterless bleaching machine can work in close loop thanks to a super efficient water management system that continuously purifies water and reintroduces it in the cycle.

Start now being finally really sustainable!

WOVEN FABRIC

Bleaching process line layout starting from greige (NOT desized) cotton woven fabric:

After plasma functionalization, fabric is impregnated with Grinp cavitational impregnation unit (impregnation of desizing and bleaching agents), reacts in the plasma steamer and, as last step, it is neutralized in Grinp cavitational neutrawashing. The outpout of the machine is bleached cotton fabric.

TERRY TOWEL

Bleaching process line layout starting from greige (NOT desized) cotton terry towel:

Towel is impregnated with Grinp cavitational impregnation unit (impregnation of desizing and bleaching agents), reacts in the plasma steamer and it is then neutralized in Grinp cavitational neutrawashing. The outpout of the machine is bleached cotton terry towel.
