WASSERABSORBIERENDE STRUKTUREN |
摘要 |
<p>Water absorbent structures are disclosed which are intended for use as wound dressings, disposable nappies (diapers) or similar applications. The structures comprise a flexible porous substrate, e.g. an open-cell foam web which is impregnated with (a) a solid, water-insoluble water absorber which has a fine particle size and is capable of absorbing at least 30 times it weight of water and (b) a hydrophilic binder which retains the water absorber in the substrate and comprises a substantially non-cross-linked, water-insoluble, hydrogel forming polymer. Component (a) has a high affinity for water due to the presence of hydrophilic groups in the polymer, but is insoluble in water and in common organic solvents. Component(b) is also water-insoluble, but because of its non-cross-linked structure is soluble in common organic solvents, such as ethanol.</p> |
