Abstract:
The sample taken is made into sheet and its brightness and tensile index are checked viz. 72.62 and19.94 Nm/g . This sample is bleached with conventional bleaching sequence of CEHH.
In this experiment we are trying to get a simple in line operation change in the bleaching sequence and change it to ECF sequence so that we can replace the CEHH with more environmental friendly sequence.
We are going to use ODED, OD(EP)D and OD(EOP)D sequences for the particular purpose with variations in D stage charges
