A method of making nonwoven webs comprising providing a spinneret including a pattern of conduits forming an extrusion region; directing only a first stream of molten propylene polymer into a region adjacent the first side of the spinneret, directing only a second stream of molten propylene polymer into a region distal to the first side of the spinneret, extruding only the first stream propylene polymer through the exit openings in a first zone where the exit opening comprises exit ports in the first zone having a first density; extruding only the second stream propylene polymer through the exit openings of a second zone where the exit opening comprises exit ports in the second zone having a second density less than the first density; and the second zone is distal to the first side with the first zone being between the second zone and the first side.

Method of making uniform spunbond filament nonwoven webs

Soft point bonded nonwoven webs, and methods of making the same, are described that utilize a pattern of small, discrete bond points in a sequent pattern that together form macro-elements. The macro-elements are themselves positioned and aligned within a pattern such that mechanical stretching operations on the point bonded nonwoven webs yields soft and bulky fabrics but with reduced incidence of tearing or rupturing of the individual bond points.

Method of making a nonwoven web

An improved tear resistant wiper is provided having a repeating pattern of thin, closely spaced curvilinear embossed elements adjacent the leading edge of the wipe and which pattern extends inwardly less than a third of the length of the wipe. The linear emboss elements have a high aspect ratio and narrow width in order to obtain a high density of embossments such that discrete unembossed regions within the leading edge region are small and yet the overall unembossed area still occupies at least 70% of the surface area.

Tear resistant wiper

The present invention relates to a nonwoven composite comprising an elastic film bonded to a nonwoven web at a plurality of strategic, geometric bond points to provide a tactile pattern, enhanced breathability and comfort to the end user.

A method and apparatus are provided for separating a discrete element from a first substrate web, moving at a first speed, and placing the discrete element on a second substrate web, moving at a second speed. The apparatus includes a first station, wherein perforations are made in the first substrate web, and a second station, wherein the discrete element is separated from the first substrate web at a line of perforations and the discrete element is transferred to a positioned on the second substrate web. The first station includes a perforation cutter assembly and conveyer assembly. The perforation cutter assembly includes first and second rollers with a cutting blade, with a discontinuous edge, and an anvil surface, respectively, to make perforations in the first substrate web. The second station includes a separation and transfer mechanism having separation and transfer segments for separating and transferring the discrete element from the first substrate web to the second substrate web. The method includes the steps of: making perforations across a width, at least partially through a thickness, and at predetermined spaced apart intervals along a length of the first substrate web; separating the discrete element from the first substrate web along a first line of the perforations; and placing the discrete element on the second substrate web.
