  • Method for fabricating olefin tarpaulins
    Patent number: 5795516
    Abstract: A method for fabricating olefin tarpaulins by treating both sides of a base fabric woven from high strength polyester filaments with a coating composition using an extruder followed by compressing the coated polyester fabrics with a calendering roller. The coating composition is obtained by dry-blending or melt-blending LLDPE (linear low density polyethylene) or LDPE (low density polyethylene) in an amount of 15.about.94.5% by weight with an elastomer of ethylene-.alpha.-olefin co-polymer of 5.about.60% by weight which are (i) ethylene propylene rubbers or (ii) co-polymers of ethylene and octene or butene; coloring master batch chip in an amount of 0.5.about.15% by weight obtained by mixing LLDPE or LDPE with pigments or titanium dioxide; and adhesion-preventing master batch chip of 0.about.10% by weight obtained by mixing LLDPE or LDPE with silica or calcium carbonate.
