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.
Claims37
A composition consisting essentially of:
- from about 0.25% to about 55% by weight of an essentially nonhalogenated polymer having a glass transition temperature above room temperature;
- from about 0.05 to about 50% by weight of polymer of an ionic, non-polymeric fluoro surfactant with from 5 to 30 carbons per hydrophilic end;
- and
- at least about 40 percent by weight of composition of a carrier in which said polymer is dissolved or suspended.
