Eco-leather yog cov khoom tawv tawv uas nws cov ntsuas ecological ua tau raws li qhov yuav tsum tau ua ntawm ecological qauv. Nws yog cov tawv tawv uas ua los ntawm crushing khib nyiab tawv, scraps thiab muab pov tseg tawv, thiab ces ntxiv adhesives thiab nias. Nws belongs rau tiam thib peb ntawm cov khoom. Eco-leather yuav tsum ua kom tau raws li cov qauv tsim los ntawm lub xeev, suav nrog plaub yam khoom: dawb formaldehyde, hexavalent chromium cov ntsiab lus, txwv azo dyes thiab pentachlorophenol cov ntsiab lus. 1. Dawb formaldehyde: Yog tias nws tsis raug tshem tawm tag nrho, nws yuav ua rau muaj kev phom sij rau tib neeg lub hlwb thiab ua rau mob qog noj ntshav. Tus qauv yog: cov ntsiab lus tsawg dua 75ppm. 2. Hexavalent chromium: Chromium tuaj yeem ua tawv tawv thiab elastic. Nws muaj nyob rau hauv ob hom: trivalent chromium thiab hexavalent chromium. Trivalent chromium tsis muaj teeb meem. Ntau hexavalent chromium tuaj yeem ua rau tib neeg cov ntshav. Cov ntsiab lus yuav tsum tsawg dua 3ppm, thiab TeCP tsawg dua 0.5ppm. 3. Banned azo dyes: Azo yog ib qho hluavtaws dye uas tsim cov tshuaj tsw qab amines tom qab kev sib cuag nrog daim tawv nqaij, uas ua rau mob qog noj ntshav, yog li no cov hluavtaws dye yog txwv. 4. Pentachlorophenol cov ntsiab lus: Nws yog ib qho tseem ceeb preservative, tshuaj lom, thiab yuav ua rau lom deformities thiab mob cancer. Cov ntsiab lus ntawm cov khoom no hauv cov khoom tawv tawv yog 5ppm, thiab cov qauv nruj dua yog tias cov ntsiab lus tsuas yog qis dua 0.5ppm.
