Abstract
Preparation of a fluorocarbon compound used to make a soil-resistant yarn is improved by removing most of the impurities from the fluoro-carbon compound mass with heat and vacuum after the final washing step and then adding an emulsifier to the fluorocarbon compound mass so that the mass can be handled as a liquid concentrate rather than a tacky solid.
