Abstract: The present invention relates to an adjustable air shield (18) for skewed godet rolls (12, 14). The air shield (18) can be any blocking type plate with or without perforations. Furthermore, these air shields (18) may be placed in close proximity to the pair of skewed, relax rolls (12, 14) in the relax zone of a fiber producing process. The plates (18) are positioned on the inside of the threadline (16) so that the airflow is substantially reduced around the threadline (16) on the skewed rolls. The preferred embodiment of the present invention is one or more skewed godet rolls (12, 14) in the relax area of the fiber production process with air shields (18) positioned on the inside of the fiber string up (threadline) (16) between the pair of skewed rolls (12, 14), such that the gap between any roll (12, 14) and any air shield (18) is uniform and constant.

Abstract: A synthetic polymer filament is characterized by a four-sided void that extends centrally and axially through the filament. Each apex of the void extends toward the approximate midpoint of one side of the exterior configuration of the filament. The four-sided void has a modification ratio in the range from about l.2 to about 2.0 and occupies from about five percent 5% to about thirty percent 30% of the cross sectional area of the filament. A spinneret plate for producing the thermoplastic synthetic polymer filament has a cluster of four orifices centered about a central point. Each orifice includes a generally isosceles triangle-shaped major portion from which extends a pair of legs, each leg of one orifice being spaced from the leg of an adjacent orifice to define a gap therebetween.
