Triarylmethane Dyes for Artificial Repellent Cotton Fibers

Abstract

Families of new hydrophobic and/or oleophobic triarylmethane dyes possessing long hydrocarbon or polyfluorinated chains have been prepared. When covalently grafted on to cotton fabric, these dyes give rise to a new type of colored superhydrophobic fibers.

Keywords: cotton fabric; oleophobicity; superhydrophobicity; surface modification; triarylmethane dyes.
