Superspreading, Skein Wetting, and Dynamic Surface Tension Milton J. Rosen* and Li D. Song Surfactant Research Institute, Brooklyn College of The City University of New York, Brooklyn, New York 11210 Received March 21, 1996. In Final Form: July 1, 1996X A study has been made of the spreading of 0.1% aqueous solutions of “superspreading” trisiloxane surfactants, especially the one made with 7.5 mol of ethylene oxide (L-77), on the hydrophobic surface Parafilm, their dynamic surface tension, and their Draves skein wetting time. No relationship was found between “superspreading” and Draves Skein wetting. The low surface tension of the wetting solution at short time (
