Abstract
A coating composition useful for imparting fire resistance and water-repellency to fabric comprises between about 5% and about 23% by weight of a liquid chlorinated paraffin, between about 20% and about 40% by weight of a resinous chlorinated paraffin, between about 4% and about 12% by weight of a copolymer of ethylene and vinyl acetate, between about 3% and about 18% by weight of a fire retardant, and up to about 15% by weight of an organic solvent. A novel water-repellent and fire resistant fabric material, and a method of preparing such material by coating tentage fabric with the composition of the invention are also disclosed.
Claims9
A method of imparting fire resistance and water-repellency to fabric comprising the steps of
- heating to flow temperature a melt composition between about 5% and about 23% by weight of a liquid chlorinated paraffin, between about 20% and about 40% by weight of a resinous chlorinated paraffin, between about 4% and about 12% by weight of a copolymer of ethylene and vinyl acetate, between about 3% and about 18% by weight of a fire retardant, and up to about 15% by weight of an organic solvent;
- delivering the heated composition to a surface of a portion of fabric;
- uniformly applying said composition over a predetermined area of said surface;
- and
- cooling said composition to form a thin adherent fire retardant and water-repellent film substantially covering said area of said fabric surface.
A fire resistant, water-repellent material comprising fabric having a substantially uniform dry coating on the surface thereof, said coating being derived from a molten coating composition comprising between about 5% and about 23% by weight of a liquid chlorinated paraffin, between about 20% and about 40% by weight of a resinous chlorinated paraffin, between about 4% and about 12% by weight of a copolymer of ethylene and vinyl acetate, between about 3% and about 18% by weight of a fire retardant, and up to about 15% by weight of an organic solvent.
