Abstract

Iyilestirilmis karekteristikleri haiz bir emici malzeme (20,300,400,520) temin edilmistir. Emici malzemeyi imal etmek için bir islem temin edilmistir. Emici malzemeden en az bir katmanli bir tabaka olusturulur ve selülozik lifler (32,532) ile süper-emici malzemenin (40,540) bir karisimini içerebilir. Tabaka yogunlugunu arttirmak için tabakanin nem muhteviyati arttirilir. Ardindan tabaka yogunlugunu daha da arttirmak ve tercihen tabaka içinde hidrojen baglanmasi da gerçeklestirmek için tabaka yüksek sicaklikta sikilastirilir. Bir düzenlemede bir kagit katmani (22,522) temin edilir, suyla islatilir ve emici malzeme katmanina yapistirilir.An absorbent material (20,300,400,520) with improved characteristics is provided. A process is provided to manufacture the absorbent material. A layer of at least one layer of absorbent material is formed and may comprise a mixture of cellulosic fibers (32,532) and superabsorbent material (40,540). The moisture content of the layer is increased to increase the layer density. The layer is then compacted at high temperature to further increase the layer density and preferably to bond hydrogen in the layer. In one embodiment, a paper layer 22,522 is provided, wetted with water, and adhered to the absorbent layer.
