Abstract
Substrates such as fabrics are treated in an apparatus that includes a chemical transfer apparatus and a transport means which conducts the substrate past the chemical transfer apparatus. The chemical transfer apparatus applies a solid chemical treatment mixture to the substrate continuously as the substrate is transported past the chemical transfer apparatus. The chemical treatment mixture includes a monomer that is cured by free radical polymerization. The applied chemical treatment mixture is then cured on the substrate by free radical polymerization. This invention provides a dry alternative to conventional wet coating methods, and avoids many of the problems associated with wet coating methods.
