Method of treating nonwoven fabrics with non-ionic fluoropolymers

Snowden, Powers and Schorr of Kimberly-Clark, Wisconsin improved the alcohol repellance of a nonwoven fabric by treating with aqueous  a non-ionic fluoropolymer such as fluoroalkyl acrylates, fluorinated siloxanes, fluorinated silicones and fluorinated urethanes.  (RDC 1/11/2011)

Miccio et al of the University of Mar del Plata and National Research Council, Argentina and the Universidade Federal do Paraná, Brazil functionalized epoxy-based networks by the preferential surface enrichment of perfluorinated tails to achieve hydrophobic surface.  It was found that both series showed high hydrophobicity and oleophobicity, independently of the crosslink density, bulk composition, and curing conditions.  XPS measurements showed a surface composition much richer in fluorinated segments than expected from bulk composition. Fluorine enrichment was also manifested at the polymer/aluminium interface for JEFFAMINE-based networks.  (RDC 1/27/2011)
