  • Flame-retarding support inlay with improved adhesion
    Patent number: 6197707
    Abstract: An improved bituminized flame-retardant textile material is provided that effectively overcomes bitumin adhesion difficulties associated with products of the prior art wherein the flame-retardant present on the surface of a textile support interfers with and hinders the achievement of bitumin adhesion. An anti-flame agent is applied in a quantity of 20 to 100 grams per square meter over 30 to 90 percent of the upper surface of the textile support. The remaining portions of the upper-surface of the textile support are free of the anti-flame agent. It surprisingly has been found that the surface portions of the textile support that are free of the anti-flame agent provide areas for the achievement of optimum bitumin adhesion with the textile support while still making possible entirely satisfactory flame retardancy for the overall product.
