A method of forming a composite sheet material, the method comprises energising a pair of electrodes to apply an electrostatic charge to a bed of fibres located therebetween thereby orienting at least some of the fibres to be substantially orthogonal to the electrodes and sandwiching at least some of the oriented fibres between a first sheet and a second sheet. The first sheet may be subsequently removed. A third sheet may be used to sandwich the fibres between the second sheet and the third sheet. Apparatus (100) is disclosed for carrying out the method.

A process for making an erosion control mat includes rotating a cylindrical drum having a plurality of mold cavities; depositing a paste into the mold cavities; selecting the sheet of mesh material to have sufficient tensile strength to join the blocks of hardened paste together without tearing or separating from the blocks of hardened paste, and to have sufficient density to retain the paste within the mold cavities as the drum rotates; covering an outer surface of the cylindrical drum and outer surfaces of the paste with the sheet of mesh material; continuing to rotate the cylindrical drum as the paste hardens into dimensionally stable blocks, and holding the sheet against the outer surface such that the sheet retains the paste within the mold cavities and the sheet becomes embedded in the paste; and separating the dimensionally stable blocks from the mold cavities.

A non-woven mat of randomly oriented thermoplastic or polymeric fibers defining interstitial gaps that form interference pathways for non-direct water flow therethrough, whereby the mat being disposed on a ground surface moderates a rate of flow of environmental water for increased seepage of the environmental water into a subground and resists rapid lateral flow of environmental water across the ground cover, and with a stabilization layer in a bottom surface portion of the mat or optionally secured with staples to the ground. A method of forming a stabilized water flow control ground cover is disclosed.

A ground cover is disclosed having a non-woven layer or mat of randomly oriented polymeric fibers coupled to an underlying porous or water permeable geomembrane or base layer of a polymeric material. The ground cover may include tufts or strands of the synthetic turf or grass bonded to the base layer.

The presently disclosed subject matter relates to nonwoven materials and their use in cleaning articles. More particularly, the nonwovens are layered structures including a rough outer surface which are useful for scrubbing and cleaning purposes.

A method of making a disposable absorbent article with a plurality of conforming features is described. The conforming features may be provided to the absorbent article in a variety of zones to allow for customizable conformance in particular regions of the absorbent article. And, the provision of these zones can also allow for customizable fluid kinetics in particular regions of the absorbent article.

A disposable absorbent article has a topsheet; a backsheet; an absorbent core disposed between the topsheet and the backsheet; and a first plurality of conforming features in at least the absorbent core or a combination of the absorbent core and the topsheet. At least a portion of the are depressions, wherein the depressions have a depression centerline bisecting a length and/or width of the depression. A first strut forms a first sidewall of the depression opposite a second sidewall of the depression formed by a second strut, wherein neither of the first strut nor the second strut extend longitudinally and/or laterally beyond the depression centerline by more than 0.75 mm.
