Abstract

The paper presents studies on the influence of selected parameters of water used in fatliquoring. Water of varying hardness (quantities of calcium, magnesium, iron compounds and of chlorides) was used in the process. Properties of fatliquoring emulsions containing waters of different hardness were determined. It was noted that emulsions were less stable in the presence of electrolytes. Generally, the average particle size of prepared fatliquoring emulsions increased if the water phase contained: calcium, magnesium, iron compounds and chlorides. The presented studies on the effects on tanned hides confirmed the desirability of using low hardness water without iron and chlorides.
