A one bath chemo-enzymatic process for preparation of absorbent cotton

SummaryCotton is the raw material for preparation of absorbent cotton. Raw cotton has to be subjected to scouring and bleaching processes for making it absorbent by removing the naturally present wax, protein and minerals in the fibre. The scouring is done at 115°C using alkali followed by bleaching at boiling condition using alkaline hydrogen peroxide solution. The effluent coming out of such processes contains high COD and BOD values. Due to the stringent environmental regulation and great awareness among the public about environment, worldwide attempts have been made to develop green and sustainable chemical processing of materials. Based on the above, in the present study efforts have been made to develop an eco-friendly one bath preparatory process for the production of absorbent cotton using chemo-enzymatic formulation. The result indicated that absorbent cotton produced using the developed process fulfilled the required performance properties as per pharmacopoeia in comparable with the conventional process made one
