IPC: D04H1/58
Filed: 1992-04-03
Abstract: A method and apparatus for manufacturing a non-woven fabric printed with a decorative pattern.   A fibrous starting material whose individual fibers are capable of movement relatively to one another under the influence of applied fluid forces is subjected to a fluid stream for entangling the fibers to form a unitary fibrous network.          The unitary fibrous network is impregnated with liquid binder which solidifies and consolidates the non-woven fabric.   Before the binder has cured and is still in a liquid condition, the unitary fibrous network is printed with a decorative pattern.   Subsequently,  the unitary fibrous network is dried to simultaneously cure the binder and the colorant forming the decorative pattern.
