the easy test method to estimate the mercerizing effect described bellow
After mercerization we need to test the effect of mercerization on textile fibre. We can estimate this by Easy-Test method. The easy-test method is described below:
Ø At first take 10ml of 0.25N Ba (OH) 2 in a beaker, then titration with 0.1N HCl and methyl orange as an indicator.
Ø At the end point yellow color solution changes to pink color solution and then the titration is completed.
Ø The measure the amount of HCl used for titration, Let HCl= x ml
Ø Now take 2gm of mercerized sample
Ø Then the sample is immersed into the 30ml of 0.25N Ba (OH)2 solution for 4hoursand then taken out.
Ø Then take 10ml of left out Ba (OH)2 solution by pipette in a beaker.
Ø Now titration with 0.1N HCl and methyl orange as an indicator.
Ø The measure the amount of HCl used for titration, Let HCl= y ml
