    • A foam core cleaning element of stitch-bonded construction having a multi-surface operative cleaning face. The cleaning element includes at least one fluid absorbing layer of absorptive polymeric foam. At least a first plurality of yarns extends in discontinuous patterned stitched relation through discrete selected zones of the fluid absorbing layer such that the first plurality of yarns forms a patterned array of first surface loop zones projecting outwardly away from a first side of the fluid absorbing layer in a defined patterned arrangement across the operative cleaning face of the cleaning element. A plurality of stitch-free zones of the polymeric foam define outwardly projecting convex curved surfaces at positions adjacent to the first surface loop zones across the operative cleaning face of the cleaning element.
    • 具有多表面操作清洁面的缝合结构的泡沫芯清洁元件。 清洁元件包括吸收聚合物泡沫的至少一个流体吸收层。 至少第一组多根纱线以不连续的图案化缝合关系延伸穿过流体吸收层的离散选定区域,使得第一多根纱线形成第一表面环形区域的图案阵列,该第一表面环形区域从流体吸收层的第一侧向外突出 以清洁元件的操作清洁面的限定图案化布置。 聚合物泡沫的多个无缝区域在穿过清洁元件的操作清洁面的与第一表面环区相邻的位置处限定向外突出的凸曲面。
