PROCESS FOR MAKING ABSORBENT ARTICLES |
摘要 |
<p>The invention concerns a process for manufacturing a water-absorbent article in which particles of a water-swellable polymer are fixed to a water-absorbent substrate. The process includes the steps of forming on the surface of the water-swellable particles a coating of a thermoplastic adhesive resin; locating the coated particles in their unswollen and dry state on or within the water-absorbent substrate also in the dry state; and applying heat to soften the thermoplastic coating of the particles and pressing the particles and substrate to cause the particles to be bound to the substrate.</p> |
