ABSTRACT:
There is disclosed an improved feedstock package for a spiraling machine. The package comprises filamentary yarn having a twist of less than 5 tpi wound around a king spool. In contrast to prior art cone packages, the invention significantly reduces package distortion and threadline breakage in high speed spiraling operations employed in, for example, making reinforced plastic hose. Preferred embodiments include the yarn being greige yarn and the package rotational speeds on the spiraling machine being at least 1,400 rpm.
