  • Fabric coating compositions, method and coated fabric having dry soil resist finishes
    Patent number: 4107055
    Abstract: A fabric coating composition, including a polymer having a glass transition temperature above room temperature, an ionic fluorinated surfactant and a carrier. The preferred fluorinated surfactants have 5 to 30 carbons per hydrophylic end and include fluoro ether surfactants having radicals of the formula (CF.sub.3).sub.2 CFOCF.sub.2 CF.sub.2 -- or fluoroalkyl surfactants having radicals of the formula CnF.sub.2n+1 -- where n is 6 to 12. The polymer may be dissolved or, preferably, emulsified by an emulsifier to form a latex. The polymer is preferably applied to fabric at a rate giving a dry solids content of about 0.25 to 10%, to give dry soil resistance.
