摘要： The present invention provides a process for forming a three-dimensional, macroscopically-expanded, fluid pervious web having an improved functional surface comprised of a sheet of polymeric material having a first surface and a second surface. A plurality of discrete deposits of a water resistant resinous material having a pre-determined open time are deposited on the first surface of the sheet. The deposits of resinous material are drawn upwardly from the first surface of the sheet to form corresponding fibrils during the open time. After resinous material has cured, the sheet is fed onto a forming structure having opposed surfaces such that the sheet is in contact with the forming structure. The forming structure exhibits a multiplicity of apertures which place the opposed surfaces of the forming structure in fluid communication with one another. A fluid pressure differential is applied across the thickness of the sheet which is sufficiently great as to cause the sheet to rupture in those areas coinciding with the apertures in the forming structure and to conform with the forming structure while substantially maintaining the orientation of the fibrils. The priming and drawing steps are preferably accomplished via a screen printing roll, and the fluid pressure differential preferably comprises a high pressure jet of liquid.

摘要： The present invention relates to fluid pervious, dispersible, and flushable webs particularly suited for use in a disposable absorbent article, such as a diaper, sanitary napkin, panty liner, incontinence pad, or the like. The present invention further relates to such webs which also include an improved, functional textured surface so as to be suitable for use as a topsheet on such a disposable absorbent article. The present invention provides a fluid pervious web which disperses into fragments which are readily flushable in a normal toilet. The web preferably comprises a wetlaid apertured tissue having a temporary wet strength resin incorporated therein. The web preferably further includes a plurality of individual fibrils on a body-facing surface thereof, so as to provide a clean and dry tactile impression in use. The fibrils serve to separate the wearer's skin from the underlying tissue substrate in use. In a preferred embodiment, the web substrate is hydrophilic in nature while the fibrils themselves are hydrophobic in nature, so as to provide enhanced dryness at the uppermost surface while promoting rapid acquisition properties.
摘要翻译：本发明涉及特别适用于一次性吸收制品例如尿布，卫生巾，内裤衬垫，失禁垫等的易渗透，可分散和可冲洗的腹板。本发明还涉及这种纤维网，其还包括改进的功能性织构表面，以适于用作这种一次性吸收制品上的顶片。本发明提供一种流体可渗透的纤维网，其分散成易于在普通厕所中冲洗的碎片。纤维网优选地包括其中结合有临时湿强度树脂的湿法成网孔组织。纤维网优选在其面向身体的表面上进一步包括多个单独的原纤维，以便在使用中提供清洁和干燥的触觉印象。原纤维用于在使用中将穿用者的皮肤与下面的组织基底分离。在优选的实施方案中，幅材基材本质上是亲水性的，而原纤维本身是疏水性的，从而在最上表面提供增强的干燥度，同时促进快速获取性能。
