INVESTIGATION OF THE EFFECTS OF PUMICE STONE POWDER AND POLYACRYLIC ESTER BASED MATERIAL ON THERMAL INSULATION OF POLYPROPYLENE FABRICS

This study has aimed at the development of thermal insulation and adhesion properties of polypropylene (PP) fabric. The texture PP weft yarn, the texture weft yarn produced from hollow PP fiber and the nonwoven produced from PP fiber were used as three different raw materials, each of which was one-side coated with the mixture containing polyurethane and pumice stone powder with different concentrations in order to improve thermal insulation properties. Then the other sides of these fabrics were coated with polyacrylic ester based material so as to improve adhesion behavior of the fabrics. Finally, heat transfer coefficients of each fabric were analyzed in accordance with fabric type, concentration of pumice stone powder and polyacrylic ester based material along with adhesion properties. The results demonstrated that the increase in the concentration of pumice stone powder and the use of polyacrylic ester based material caused the decrease in the thermal conductivity coefficients. In addition, the use of polyacrylic ester based material brought in adhesion properties to fabrics in order for the ability to adhere these fabrics onto any surface.
