Oil and Water Repellent Treatments for Cotton with Fluorochemicals1

Abstract

The application of some fluorochemicals to cotton textiles to impart oleophobic and hydrophobic surface characteristics to the materials has been investigated further. The chromium complexes of perfluoromonocarboxylic acids were used in conjunction with acrylic emulsion. These were employed in separate operations as well as combined with the complexes into one emulsion. Pernuoromonocarboxytic acids were applied to fabrics after impregnation with a mordant to bond the acid to the fiber. Data are presented to show the relative effectiveness of the repellency treatments as governed by the fabric construction.
