• Product FASCL2 made by using Palmkernel Sulpho-Chlorinated Methyl-Fatty Acid Ester (10%S)

Final meeting –S.Croce S.Arno 15 October 2013

ConclusionReady to use Fatliquor

by using Sulpho-Chlorinated oil give

- Good shelf life

- Good emulsifying properties

- Good effectiveness to produce desired article

- Similar tanning power

Final meeting –Pisa ICCOM 11 December 2013

Conclusion

More similar are the chemicals characteristics of the new products (in terms of chain lenght S content and Cl content), more similar results are obtained on leather articles.

The new chlorinated and sulpho-chlorinated chemicals can be easily used to produce a common fatliquoring agent.

The new chlorinated and sulpho-chlorinated chemicals didn’t request particular application process and may be replaced instead of chlorinated and sulpho-chlorinated paraffin to produce very similar results.

ConclusionAction 9 :

In these pictures there are examples of artigianal articles made

with the leather processed with new natural fatting:

Conclusion

These are the LINEAPELLE FAIR (OCT’ 13) photos’:

• Action 11 and 12:• Have done the leather sample books

together INESCOP and natural products fatting manual

Conclusion

CONCLUSIONAction 17:

On 20 November 2013 was held in Colortex to S.Croce S.Arno the WORKSHOP ecofatting, during this there were present the Tannery technicans

and the Televison; we have explaned the complete ecofatting process and the progress of the project.
