摘要： 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.

摘要： 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.
