Abstract
An improved process for dyeing closely constructed non-tufted textile materials is provided wherein an effective minor amount of a substantially oil and water repellent fluoropolymer is applied to the textile material. The substantially oil and water repellent fluoropolymer employed can be represented schematically as ##STR1## The textile material can be, if desired, scoured with an aqueous surfactant solution to remove any residual dirt, oil or processing aids present on the textile material and thereafter scoured with an aqueous acidic solution to provide the textile materialwith an acidic pH prior to application of the fluoropolymer. Further, the back portion of the textile material can be backcoated with an elastomer composition. Once the textile material has been treated using any of the above processing steps, in combination with the application of the fluoropolymer, the resulting polymer-modified textile material is thoroughly dried and cured prior to dyeing. The application of the fluoropolymer to the textile material and its effect on the subsequent dyeing of the polymer modified textile material can further be enhanced by the use of a minor effective amount of a fluorosurfactant in combination with the fluoropolymer. The dyed products resulting from the process of the invention generally have reduced frosting and improved pattern definition and color yield.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
