| Abstract [eng] |
In this paper the investigations of moisture transfer through microporous membrane laminated leather are presented. To improve the comfort features, the leather was laser-processed using molecular gas CO2 and laminated with microporous breathable PU membrane. The influence of microporous membrane and geometrical parameters of laser cutting perforation on the leather laminate comfort properties has been investigated. Lamination with microporous membrane increases leather resistance to water penetration, decreases the water vapour permeability and intensifies the water vapour absorption. Herewith laser cutting perforation is opening the cutting surface of holes, which is able to improve the vapour penetration and sorption. The water vapour permeability and absorption were directly dependent on perforation area. |
