Eco-leather ke sehlahisoa sa letlalo seo matšoao a eona a tikoloho a fihlelang litlhoko tsa maemo a tikoloho. Ke letlalo la maiketsetso le entsoeng ka ho pshatla letlalo la litšila, likhechana le letlalo le lahliloeng, ebe le eketsa likhomaretsi le ho hatella. Ke ea moloko oa boraro oa lihlahisoa. Eco-letlalo le hloka ho fihlela litekanyetso tse behiloeng ke mmuso, ho kenyelletsa le lintho tse 'ne: formaldehyde ea mahala, litaba tsa chromium tse hexavalent, lidae tsa azo tse thibetsoeng le litaba tsa pentachlorophenol. 1. Formaldehyde ea mahala: Haeba e sa tlosoe ka ho feletseng, e tla baka kotsi e khōlō liseleng tsa motho esita le ho baka kankere. Tekanyetso ke: litaba li ka tlase ho 75ppm. 2. Hexavalent chromium: Chromium e ka etsa hore letlalo le be bonolo le ho reketla. E teng ka mefuta e 'meli: trivalent chromium le hexavalent chromium. Trivalent chromium ha e kotsi. Chromium e nang le hexavalent e feteletseng e ka senya mali a motho. Likahare li tlameha ho ba ka tlase ho 3ppm, 'me TeCP e ka tlase ho 0.5ppm. 3. Li-dyes tsa azo tse thibetsoeng: Azo ke dae ea maiketsetso e hlahisang li-amine tse nkhang hamonate ka mor'a ho kopana le letlalo, le bakang kankere, kahoo dae ena ea maiketsetso e thibetsoe. 4. Likahare tsa Pentachlorophenol: Ke ntho ea bohlokoa e sireletsang, e chefo, 'me e ka baka bokooa ba likokoana-hloko le kankere. Likahare tsa ntho ena lihlahisoa tsa letlalo li hlalositsoe e le 5ppm, 'me maemo a thata le ho feta ke hore litaba li ka ba ka tlase ho 0.5ppm feela.
