Abstract
A surgical sponge constructed of a nonwoven fabric is provided with an integral x-ray detectable element in the form of an entangled roving which is positioned on one surface of the non-woven fabric. The fabric is produced by placing the x-ray detectable element atop a fibrous web and subjecting the roving and web to hydraulic entanglement to produce a patterned, nonwoven fabric.
