THE INFLUENCE OF FATLIQOURING PROCESS ON PROTECTIVE CHARACTERISTICS OF LEATHER GLOVES

Abstract

Appropriate protective gloves are essential for industry workers to avoid hands and wrists injuries. Leather is a common material used by professionals for technical gloves. Mechanical resistance, protection against water and high temperature has to be fulfilled by leather that is intended for using in protective gloves. In this study recipes using various fatliquoring agents with different properties such as lesitin based, lanolin based, polymeric based and water proofing fat liquor were applied to produce technical glove leather and effect of each fatliquoring product on protective performance of leathers were analyzed in terms of physical and mechanical properties including tensile (ISO 3376), stitch tear (ISO 23910), tear resistance (ISO 3377-2), static (ISO 2417) and dynamicwater absorption (ISO 5403-1) and thermal stability such as dry heat (ISO 17227) and heat stability (ISO 11645). For this purpose, chromium tanned split calf leathers were used and retanning of protective leather gloves were performed by using tara and phosphonium combination. Performance testing results obtained from four different retanning processes was compared according to the type of fatliquoring material used in the production. Post-tanning with different types of fatliquoring products have significant effect on the protective performance properties of leather gloves, in terms of mechanical and thermal properties.
