    摘要： An in-line formed, non-laminated web is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed. The selective vacuum manipulation in conjunction with multiple fiber deposition heads, and appropriate timing of fiber addition therefrom, will yield a variety of useful composite webs having multiple layers thereby forming an economical single web which may be easily incorporated into an absorbent garment or article.

    摘要翻译： 在线形成的非层压纤维网适合用作一次性吸收制品中的复合流体分配和流体保留层。 可以通过选择性沉积包括吸收剂如纸浆和超吸收剂以及粘合剂纤维的气流成网材料来形成网。 如此构造的网将具有多个混合的较低基重区域和较高的基重区域共存并分布在幅材的至少中心区域中，与纤维网的X轴或Y轴或两者交叉的交替， 较高的基重区域在Z方向上的厚度大于较低的基重区域。 如此构造的网将在下基重条纹和较高基重条之间将进一步没有离散的材料边界。 此外，去除了在网上进行后续加工以实现脊状结构的必要性，并且纤维将保持整体而不受干扰。 与多个纤维沉积头结合的选择性真空操作以及从其中加入的纤维的适当时机将产生具有多个层的多种有用的复合纤维网，从而形成经济的单纤维网，其可以容易地结合到吸收性衣服或制品中。
