A method of bonding webs of fibers by chemical agents that may include adhesives and solvents. The process may entail one or more of the following methods: impregnation, spraying, printing and foam application.
NOTE: chemical bonding using chemical agents occurs only in a reactive system, e.g. a crosslinkable dispersion. Normal polymer bonding as it happens with non-reactive polymer binders (e.g. fibers, adhesives or lattices) is a physical process.
