Abstract
Disclosed is a method of producing polysaccharide foams and foams produced by the method. The polysaccharide foams are formed from a wet condition and are convection dried with a flow of warm or hot air. Such foams exhibit improvements over foams dried under ambient conditions. The present invention also discloses the formation of multi-ply foam layers. At least two sheets of foam layers are layered together and laminated either mechanically or chemically to produce a composite structure.
