Abstract:
A foam composition and a process to treat fibrous articles using a foam composition comprising an amphiphilic protein. The foam composition can impart oil and water repellency when a fluorinated additive is used. The foam composition can impart water repellency when a non-fluorinated additive is used. The described amphiphilic proteins can be hydrophobins. The density of the foam suitable for the process is from about 0.001 to about 0.5 gram per milliliter.

Abstract:
[PROBLEMS] To provide a fabric provided with a highly expanded layer by employing an expansion method wherein the expansion of thermally expandable microcapsules is not hindered even in a crosslinked resin. [MEANS FOR SOLVING PROBLEMS] A fabric bearing a highly expanded layer stuck on one side thereof, wherein the highly expanded layer is composed of thermally expanded microcapsules, a synthetic resin for holding the microcapsules on one side of the fabric, and a hydrophilic microporous silica fine powder present on the surfaces of the microcapsules or in the synthetic resin. The fabric can be produced by preparing a synthetic resin solution containing both thermally expandable microcapsules and a hydrophilic microporous silica fine powder, applying the solution to one side of a fabric either over the whole surface of the side or in patterns, drying the resulting coating to form a synthetic resin layer, and then expanding the microcapsules under heating.
