Abstract:
A continuous fabric for use in forming a repair liner for reinforcing a pipe. The fabric includes a top layer and one or more bottom layers. The width of the top layer is less than the width of the continuous fabric and the density of the top layer is less than the density of at least one of the at least one or more bottom layers. The top layer may serve as a guide for winding the fabric in an overlapping pattern about a mandrel so that the essentially only the top layer is visible in the fabric winding.
