Abstract
An air entanglement system having a housing, a first rotatable surface disposed with the housing, and a second rotatable surface disposed with the housing proximate the first rotatable surface is described herein. The first rotatable surface may comprise a first plurality of air jets configured to air entangle a preform in situ. The second rotatable surface may be disposed with the housing proximate the first rotatable surface. The second rotatable surface may comprise a second plurality of air jets configured to air entangle the preform in situ. The air entanglement system may be configured to achieve negative pressure in response to being under suction.
