Abstract
A laminate is made by first treating two spun-bond webs formed of endless thermoplastic synthetic-resin filaments with wetting agents. Then a layer of hydrophilic fibers is applied to one of the treated spun-bond webs and then the other of the treated spun-bond webs is applied to the layer of hydrophilic fibers on the one treated spun-bond web. Finally the two treated spun-bond webs and the layer of hydrophilic fibers between them are hydrodynamically consolidated together.
