A unique isotropic sub-denier spunbond nonwoven product created by an apparatus comprising a unique multi-head resin metering system, a spinneret head with spinning sections, separated by a quench fluid extraction zone, a two sided, multilevel quench system, a fluid volume control infuser system which automatically guides the filaments into the filament drawing system while conserving energy by using a portion of the quench fluid as part of the drawing fluid and also minimizing turbulence at the entrance to the draw slot. The filament drawing system comprises a draw jet assembly with adjustable primary and secondary jet-nozzles and a variable width draw jet-slot. The entire draw jet assembly is moveable vertically for filament optimization. The offset, constant flow secondary jet-nozzle system provides an unexpectedly high velocity increment to the filaments by oscillating the filaments and increasing their drag resulting in remarkably low fiber denier on the order of 0. 5 to 1. 2. The apparatus also embodies a draw jet extension with an adjustable slot and contains two in-line or tandem which are also adjustable and maintain fiber tension and draw force through the lower end of the draw system.

The present invention relates to a die body consisting of a multiplicity of modular die plates, which are easily and rapidly interchangeable. The modular die plates can be configured to extrude different shapes and types of fibers. The apparatus may also be configured to extrude multiple types of materials each from a plurality of separate ports or from a plurality of common ports. The apparatus may also be designed to include single or multiple ports to direct air or other fluids to draw or attenuate the extrudate into fibers of a desired diameter. The extrudate may be treated with the air or various other gases or fluids within the die or exterior to the die tips.

The present invention provides an improved apparatus for forming a fibrous pad for absorbent products with improved density control. Fibers entrained in a high speed air flow are deposited onto the foraminous surface of a spaced, three-dimensional pad-forming pocket. The fine foraminous pad forming screen is supported on its periphery by two top plates, a coarse forming screen, two subplates and end rails which incorporate a device to hold the pad forming screen. A gas flow regulating system consisting of precisely placed cross directional fixed and adjustable airflow control louvers controls the air flow direction and reduces spill over and turbulence during the pad formation and especially during the transition of the forming pocket into and out of the air stream as the rotary former shell rotates through the filling position. Additional control of density and fiber placement is gained through the use of additional gas control innovations including a tapering the pocket ends such that the airflow is streamlined especially during pocket transition through forming sections.
