摘要: A multifunctional material is provided for use in personal care products. The multifunctional material has a permeability between 100 and 10000 Darcys and a capillary tension between about 2 and 15 cm. Structures containing this multifunctional material can have a runoff rate of less than 25 ml per 100 ml insult, over its life. The multifunctional material should have between about 30 and 75 weight percent of a slow rate superabsorbent, between 25 and 70 weight percent of pulp and from a positive amount up to about 10 percent of a binder component. The material preferably has a density between about 0.05 and 0.5 g/cc. The material has a liquid pass through function which desorbs a surge material across time frames consistent with user conditions and releases the liquid for distribution to remote storage locations. The material, when combined with the intake and distribution materials, defines a composite structure for use in personal care products.

摘要: A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. The intake capability of the absorbent system is maintained or improved over current systems by keeping a second layer of the absorbent system at low saturation levels through as many insults of the product as possible, while providing optimum intake performance through appropriate control of the composite properties. The low saturation in this layer provides void volume for the incoming insult as well, as a high permeability, thus increasing the intake rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide an appropriately high level of capillary tension to provide enough control of the liquid to stop leakage from occurring. This low saturation layer is used in addition to a surge material and provides intake functionality in addition to that provided by the surge material. In particular aspects of the invention, the body side layer of the absorbent core does not extend over the entire surface of the overall absorbent core, therefore is not used as the high saturation, wicking layer, but as the intake layer. This arrangement also allows the intake layer to be in direct contact with the incoming liquid, therefore allowing for more immediate access and improved intake function. In additional aspects, at least one primary layer region can have a non-uniform, selectively zoned basis weight distribution. Particular configurations of the at least one primary layer region can be constructed with a target area of such primary layer region having a basis weight which is less than a basis weight of another non-target portion of the primary layer region. Moreover, at least one primary layer region can have a heterogeneous structure. In particular constructions, the at least one primary layer region can include a plurality of two or more sublayers.

摘要翻译: 独特的吸收制品包括具有多个吸收层的吸收芯,其中吸收层以这样的方式相互作用,其优先将吸收的液体定位在指定的高饱和芯吸层中。 液体在该芯吸层内的定位增加了该层由于较高的饱和水平和可用的液体量的增加而使液体通过毛细作用移动的潜力。 吸收系统的吸入能力通过目前的系统维持或改善,通过尽可能多的产品损伤将吸收体系的第二层保持在低饱和度水平,同时通过适当地控制复合材料特性来提供最佳的进气性能。 该层中的低饱和度也为进入的侮辱提供空隙体积,作为高渗透性,从而增加吸收系统整体的吸入速率,但是低饱和层的结构也是平衡的,以提供适当高的 毛细血管张力水平提供足够的液体控制以阻止发生渗漏。 除了浪涌材料之外,还使用这种低饱和层,除了由浪涌材料提供的外,还提供吸入功能。 在本发明的特定方面,吸收芯的身体侧层不延伸在整个吸收芯的整个表面上,因此不用作高饱和度芯吸层,而是用作吸入层。 这种布置还允许进气层与进入的液体直接接触,因此允许更快速的进入和改进的进气功能。
