    • A self-bonded corrugated web made from a primary pre-bonded web layer of substantially uniform thickness, which contains thermoplastic fibers,and which is arranged to form corrugations forming a corrugation pattern of parallel corrugation lines, which can be parallel to the longitudinal extension of the web, whereby the corrugated web is heat- or melt-fusion bonded in regions forming a primary bonding pattern of a plurality of primary bonding pattern lines, which are arranged non-parallel to the corrugation lines and which intersect at least two of the corrugation lines, thusly stabilizing the corrugations. Preferably, each of the corrugation lines of is connected to at least one neighboring corrugation line by at least one primary bonding pattern line.The primary bonding pattern can comprise first and second primary bonding pattern lines, which can define circumscribed regions, which are unbonded by the primary bonding pattern. The primary bonding pattern lines can be continuous lines, preferably straight lines, and it can consist of a secondary bonding pattern consisting of a plurality of bonding points. The corrugated web according preferably exhibits a low pressure loft of at least 18 [µm/(g/m 2 )]. The present invention further relates to an absorbent article comprising a self-bonded web as well as to a method for making such a self-bonded corrugated web.
    • 一种自粘合的波纹状网,其由包含热塑性纤维的基本上均匀厚度的初级预粘合纤维网层制成,并且被布置成形成波纹,其形成平行波纹线的波纹图案,其可平行于纵向延伸 所述网状物,其中所述波纹状网状物在形成多个主粘合图案线的主要粘合图案的区域中被热熔或熔融粘合,所述主粘合图案布置成不平行于所述波纹线并且与所述波纹中的至少两个相交 线,从而稳定波纹。 优选地,每个波纹线通过至少一个主键合图案线连接到至少一个相邻的波纹线。主键合图案可以包括第一和第二主键合图案线,其可以限定外接区域,这些区域是未绑定的 主要结合模式。 主要结合图案线可以是连续线,优选是直线,并且它可以由由多个接合点组成的辅助接合图案组成。 波纹腹板优选地具有至少18 [μm/(g / m 2)]的低压凸轮。 本发明还涉及一种包括自粘合纤维网的吸收制品以及制造这种自粘合波纹状网的方法。
