Abstract:

Breakthrough pressure is the external pressure required to force a composite - solid, liquid, vapor - interface to transition irreversibly to the fully wetted - solid liquid - interface. Based on theoretical models, this pressure can be calculated using material properties and an understanding of the surface geometry. The incorporation of low surface energy materials can drastically increase the breakthrough pressure of a material. Cotton fabric was treated in a variety of different tecnoflon Fluorodecylsub 8Tsub 8 solutions. These textiles were then investigated for geometrical properties by SEM and breakthrough pressure using a unique experimental apparatus. Resulting data was compared with theoretical model predictions.
