Fabric laminates

摘要

Laminates of fabric and microporous polymeric substrates are taught which have an oil repellancy rating of at least 7. The enhanced properties may be obtained by contacting the laminate or any of its components with an aqueous dispersion of polymer particles (0.01 to 0.1 microns) of an organic polymer having pendent fluorinated alkyl groups and in which the article has an oil repellency rating of at least 7. The small size promotes uniformity of coating when the laminate or components are coated with the dispersion and then heated to flow the particles together.
