ABSTRACT:
Synthetic continuous filament yarn is woven with a sacrificial filling and thus formed into a prefabric, selected portions of the prefabric are dyed, the prefabric is optionally crimped either before or after dyeing, the prefabric is immersed into a dilute solution which, when concentrated will destroy the sacrificial filling, and the prefabric is then conducted through a heating and drying operation, boiling off the water and concentrating the solution, then substantially completely destroying the sacrificial filling and freeing the warp yarns as a free warp of intermittently colored yarns.
