An elastic nonwoven laminate that contains an elastic film laminated to one or more nonwoven facings is provided. The nonwoven facing contains a conventional polyolefin and can also contain a polyolefin-based plastomer. The laminate is activated by grooving to decouple the nonwoven facing from the elastic film. To reduce fiber-pull out that can result due to activation by grooving, the laminate can be post-bonded at room or elevated temperatures and a specific range of pressures to compact the fibers of the facing and minimize fiber pull-out/fuzziness while not sacrificing the softness, elasticity, and feel of the laminate.

Method of making post-bonded grooved elastic materials

Post-bonded grooved elastic materials

A nonwoven web contains an even distribution of its composite materials by the separate application of particulate material such as superabsorbent particles into a forming head outside the air stream for deposition of thermoplastic fibers in the forming head. The thermoplastic fibers are distributed by air entertainment through tubular forming screens having rotary distribution members therein. The particulate absorbents are generally placed in the forming box by distribution units which may have metering devices and outlet chutes extending into the forming head.

Particulate addition method and apparatus

Bonded fluff structures and a method for producing such bonded fluff structures in which a pulp sheet having a material suitable for producing fluff and a heat activatable fiber material is fiberized to produce a mixture of fluff and heat activatable fibers. The mixture is contacted with a hot air stream, heating the heat activatable fibers to an activation temperature. The resulting heated mixture is then deposited onto a forming structure, forming a bonded fluff/fiber composite matrix structure.
