A method for making a zoned apertured nonwoven web comprises providing an unapertured nonwoven web having a first plurality of weakened locations in a first pattern in a first zone and a second plurality of weakened locations in a second pattern in a second zone. The method comprises applying a substantially cross machine directional tensioning force to the nonwoven web to cause the nonwoven web to rupture at some of the first and second pluralities of weakened locations. The applying step creates a plurality of first apertures in the nonwoven web coincident with the some of the first plurality of weakened locations and a plurality of second apertures in the nonwoven web coincident with the some of the second plurality of weakened locations. The cross machine directional width of the nonwoven web after the applying step is substantially the same in the first zone and the second zone.

A perforated non-woven fabric having at least one fiber layer that has a plurality of through holes. The total area of the through holes accounts for 1080% of the total area of the perforated non-woven fabric; the opening of the through holes is flat with the surface of the perforated non-woven fabric; and the density of through holes on the perforated non-woven fabric is 3/cm.sup.2100/cm.sup.2. The fiber density at the edge of each through hole is similar to or the same as the fiber density in other areas of the perforated non-woven fabric. The fiber surrounds the through hole, and only the surface of the fiber is bonded to each other.

The present invention relates to a molded object and a method for manufacturing the same. The molded object according to the present invention has high density and enhanced properties such as flexural strength or tensile strength, has a small weight change caused by moisture absorption even when used for a long period of time, and has small changes in flexural strength, tensile strength and the like, and therefore, is suited to be used as household materials, industrial materials or the like.

The invention provides a connector assembly for fastening filter elements onto a supporting plate of a press filter, comprising a first cylindrical core, a first flange extending outward from the first cylindrical core, a second cylindrical core, and a second flange extending outward from the second cylindrical core. The first cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with a central through hole of the supporting plate, and the second cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with the first cylindrical core. Both the first cylindrical core and the first flange and both the second cylindrical core and the second flange are respectively molded integrally from a non-woven fabric which has the ability of self-sustaining and shape maintenance, and is moldable. The invention also relates to a press filter fitted with the connector assembly.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.
