Plasma-induced graft polymerization of diallyldimethylammonium chloride (DADMAC) and [2-(acryloyloxy)ethyl]trimethylammonium chloride (AOETMAC) on cotton followed by dyeing with direct dyes was studied using different concentrations of the monomers and plasma conditions, and the color yield was evaluated using K/S measurements. Colorfastness and staining after laundering were evaluated using the standard grayscale. A significant increase of 149% in color yield was achieved when 30 g/L of DADMAC was used. 100–300% increase in K/S was achieved when ∼20 g/L of AOETMAC was used. To enhance the wash and lightfastness of the direct dyes on cotton, plasma-induced graft polymerization of 1,1,2,2-tetrahydroperfluorododecyl acrylate was achieved on the dyed cotton and showed considerable enhancement in both the wash and lightfastness.}, number={31}, journal={INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH}, author={Ramamoorthy, Amsarani and Helmy, Hany M. and Rajbhandari, Rajeev and Hauser, Peter and E-Shafei, Ahmed}, year={2016}, month={Aug}, pages={8501–8508} }

The influence of process parameters on the performance of polyfluorocarbon was studied using water contact angle measurements, water/alcohol, and oil repellency tests, X‐ray photoelectron spectroscopy, and scanning electron microscopy. A design of experiments for different processing conditions was used. Plasma assisted‐graft polymerization of fluorocarbon in presence of the crosslinker di(ethyleneglycol) diacrylate (10:1 molar ratio of monomer/crosslinker) resulted in a polyfluorocarbon nanolayer on cotton, which was hydrophobic and durable to five home launderings.magnified image
