ABSTRACT:
An apparatus for forming artificial fibers and a non-woven web therefrom includes a device for generating a substantially continuous fluid stream along a primary axis, at least one extrusion die located adjacent to the continuous fluid stream for extruding a liquefied resin into fibers, a member for entraining the fibers in the primary fluid stream, and a perturbation mechanism for selectively perturbing the flow of fluid in the fluid stream by varying the fluid pressure on either side of the primary axis to produce crimped fibers for forming the non-woven web. The inventive manufacturing method finely tunes non-woven web material characteristics such as tensile strength, porosity, barrier properties, absorbance, and softness by varying the fluid stream perturbation frequency and amplitude. Finally, the inventive apparatus may be implemented in combination with melt-blown, spunbond and coform techniques for producing non-woven webs.
