发明名称 Disposable sanitary absorbent incontinence pad
摘要 A coverstock for disposable sanitary absorbent products is described. It comprises a non-woven web having a body-contacting surface and a material-contacting surface. The web is partially impregnated in selected areas with a fluid-repellent material such as a hot-melt adhesive. The penetration of the repellent material extends from the material-contacting surface, a distance toward the body-contacting surface at least 5% and not more than 95% of the thickness of the web so that the body-contacting surface is free of fluid-repellent material, and so that the material-contacting surface can be secured to the material by application of heat and without any additional adhesive material. A disposable absorbent pad made with the coverstock material, and the process for making the coverstock material and the pad are also disclosed.
