Abstract

Pronalazak se odnosi na postupak za štavljenje zakišeljenih vlažnih sirovih koža. Ovaj postupak se sastoji od (a) izrade tečnog organskog kupatila nerastvorenog u vodi, (b) suspendovanja u ovom kupatilu mineralnog agensa za štavljenje na bazi metalnog jedinjenja, naročito soli ili kompleksa hroma, (c) podešavanja nivoa hidratacije kože izmedju minimalne granične vrednosti od 200% (masa vode u odnosu na masu suve kože) i ispod najviše granične vrednosti koja odgovara granici zadržavanja vode u koži, (d) dovodjenja u dodir tako hidratisanih koža u organskom kupatilu koje sadrže agens za štavljenje u toku trajanja najmanje od 4 sata i laganog uvodjenja u kupatilo baze tako da se postupno povećava pH zadržane vode u kožama do krajnje vrednosti koja iznosi izmedju minimalne granične vrednosti od 3,9 za agens za štavljenje hromom, i maksimalne granične vrednosti od 4,4 za ovaj hromni agens, i (e) vadjenja kože iz kupatila i ostavljanja da odstoje najmanje 24 sata. Postupak pronalaska omogućava da se jednovremeno dobije potpuno iscrpljivanje kupatila za štavljenje, otsustvo rasprostiranja agensa za štavljenje u kasnije operacije završne obrade i koža dobrog kvaliteta.
