Influence of drying temperature on sorption properties of hydrophobic synthetic tanned leather

In this paper the influence of drying temperature on the sorption properties of bovine synthetic tanned hydrophobic leather was investigated. The leathers were dried on a vacuum dryer at a temperature of 40, 45, 50 and 55 ° C for a period of 90 seconds after tanning, retanning, dyeing and fatliquoring in a real production process. By examination the moisture absorption, water penetration time and water absorption of the leather during the dynamic movement on the penetrometer, a significant influence of the drying temperature on the sorption properties of the leather was determined.
