摘要： An in-line formed web or other material (such as foams) having major surfaces in the X-Y plane and a depth in the Z direction is suitable for use as an integral fluid distribution and fluid retention material in a disposable absorbent article. The web or material contains multiple zones of material which may have both thermoplastic fibers/materials and absorbent material components. The multiple zones can have different compositions of thermoplastic fibers/materials and absorbent material as applied in-line by various arrangements of thermoplastic melt dies and absorbent fiber/material dispensers. By arranging at least two of the multiple zones in an opposing relation overlaid in the Z-axis direction of the web/material, a gradient can be formed in the Z-direction of the web/material. In the case of airforming, by coordinating the timing and deposition of the material onto a forming wire, at least one of the multiple zones is arranged to have intermittent material deposition in at least one of a machine direction or a cross direction of the web. Thus the in-line formed integrated web has a Z-direction gradient of air laid material zones and zones of different materials intermittently placed in one of the machine direction or the cross direction and may be customized according to the specific need for a single overall structure having fluid intake, distribution and retention properties in an absorbent article.
摘要翻译：在X-Y平面中具有主表面并且在Z方向上的深度的在线形成的网或其它材料（例如泡沫）适合用作一次性吸收制品中的整体流体分配和流体保留材料。纤维网或材料包含可以具有热塑性纤维/材料和吸收材料组分的多个材料区域。多个区域可以具有不同组合的热塑性纤维/材料和吸收材料，通过热塑性熔体模具和吸收性纤维/材料分配器的各种布置在线应用。通过将多个区域中的至少两个以相对的关系布置在幅材/材料的Z轴方向上，可以在幅材/材料的Z方向上形成梯度。在成形的情况下，通过将材料的定时和沉积协调在成形网上，多个区域中的至少一个被布置成在幅材的机器方向或横向方向中的至少一个中具有间歇材料沉积。因此，在线形成的一体网状物具有空气铺设材料区域的Z方向梯度和不同材料的区域间歇地放置在机器方向或横向之一上，并且可以根据具体需要定制为单个整体结构在吸收制品中具有流体吸收，分布和保持性能。

摘要： An absorbent fibrous foam composite comprising a fluid intake capacity of at least 15 g/g, a vertical wicking distance of at least 10 cm, and an absorbency under zero load of at least 15 g/g. The absorbent fibrous foam composite comprising a water insoluble fibrous material and a superabsorbent material. The absorbent fibrous foam composite made by forming a slurry of water, a water-insoluble fiber, and a binding agent. A water-swellable, water-insoluble superabsorbent material is added to the slurry and the temperature is lowered until the water freezes. The frozen water is then removed by sublimation process and an absorbent fibrous foam recovered. The Gelation Time, which represents a fluid absorption rate of superabsorbent during the preparation, is critical to preparing uniform absorbent freeze-dried foams and can be adjusted by various mixing conditions and physical and chemical superabsorbent treatments.

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。

摘要： A thermoplastic foam composite has at least one active agent layer, which includes active agent materials that are coated with a thermal-sticky polymer, and which is bonded to at least one surface of a soft, flexible, absorbent thermoplastic foam layer. The thermoplastic foam composite can exhibit desirable active agent properties while maintaining sufficient integrity, absorbency, and/or flexibility for specific applications. In some aspects, an adhesive can be utilized to assist with bonding the active agent layer to the thermoplastic foam layer. The thermoplastic foam composite can be utilized as an article, such as a packaging, wiper, towel, or insulation product, or can be incorporated as a component into a variety of other articles, including personal care articles, health/medical articles, and household/industrial articles, for example.
