In 2009, the Italian company Canepa, an international leader in silk production, developed the SAVEtheWATER® Kitotex® patent. This patent reduces water consumption by up to 90% and saves 60% of electricity, in addition to the non-introduction of CO2 and the total elimination of methacrylamide and polyvinyl alcohol (PVA, the dissolved plastic) in the process of preparing yarns for weaving.
All this is possible thanks to the use of the exoskeleton of crustaceans, waste of the food industry, from which Canepa obtains the "chitosan", a biodegradable and non-toxic organic substance, which in addition to what is listed above, allows to drastically cut the use of detergents, bleaches and other chemical agents used in the usual processing. The benefit is not only environmental. In fact, the tissues naturally acquire a number of characteristics that benefit the health of consumers such as bacteriostaticity, which prevents the harmful proliferation of bacterial flora, and the anti-mite and antistatic effect, important for improving the hygiene and prevent dust allergen.
Canepa makes its know-how available through licensing agreements with companies and partners in the clothing-textile industry.
