APPLICATIONS : |
| It
is a general-purpose detergent & is most suitable for stripping
of vegetable tanned E.I leathers. About 1 to 1.5% on the dry weight
of leathers, along with mild alkalies, gives, clean leathers, stripping
off most of the soluble tans, oils & greases, and prepare them
for receiving a fresh retannage. The best method is to run the rinsed
leathers with the detergent for 1 to 1 ½ hour and keep overnight
in the bath, and next day proceed with the stripping with additional
alkalies as required followed by through washing. Blue chrome leathers
stored in wet condition for a long time can be pre-washed with 0.2
to 0.6% of DECIWET- N on shaved weight in warm water followed by washing
and neturalizing, etc. to get uniform results due to uniformly wetted
leathers. It can be used in the rewetting of mineral tanned crust
leathers. |
