摘要： A disposable diaper combining improved softness and sufficient strength to resist in use tearing and shredding in a single structure, thereby producing better compliance and fit when the structure is applied to the wearer, and hence improved comfort as well as better containment of waste fluids deposited thereon. In a preferred embodiment, a disposable diaper of the present invention employs an air laid absorbent cellulosic core reinforced by the application of a hydrophobic resin at relatively low levels of solids addition to one side thereof with subsequent drying, curing and calendering to the desired overall density. With sufficient strength built into the resin treated surface of the absorbent core structure, the unreinforced surface of the absorbent core can be adhered directly to a soft, waterproof backsheet, thereby producing a unique softness, texture and hand. In addition to improved strength and softness, a resin-stabilized absorbent core of the present invention exhibits improved surface dryness due to favorable density and capillary gradients which provide improved liquid penetration from the resin treated surface of the core to the non-resin treated portions of the core. By combining the resin-stabilized absorbent core with a fast strike-through topsheet in a disposable diaper structure, the gasket-like waterproof side flaps normally required to prevent liquid run-off can be eliminated.
摘要翻译：一种一次性尿布，其结合改善的柔软性和足够的强度以抵抗使用中的撕裂和粉碎在单一结构中，从而当将结构应用于穿着者时产生更好的柔顺性和适应性，并且因此改善舒适度以及更好地容纳沉积在其上的废物流体。。在优选的实施方案中，本发明的一次性尿布采用通过施用疏水性树脂而增强的气流成网吸收性纤维素芯，其中一个侧面具有相对低的固体含量，随后干燥，固化和压延至期望的总密度。在吸收芯结构的树脂处理表面内置足够的强度，吸收芯的未增强表面可以直接粘接到柔软的防水底片上，从而产生独特的柔软度，质感和手感。除了改进的强度和柔软性之外，本发明的树脂稳定的吸收芯由于有利的密度和毛细管梯度而表现出改善的表面干燥度，其提供了从芯的树脂处理表面到非树脂处理部分的改进的液体渗透核心。通过将树脂稳定的吸收芯与一次性尿布结构中的快速穿透顶片组合，可以消除通常所需的垫片状防水侧翼，以防止液体流出。
