    • Web constructions with severed elongate strands (242) located on at least one surface are described. The severed elongate strands are attached to one or both major surfaces of a web (110) and may be arranged in rows and columns. The elongate strands may be formed by extruding continuous strands onto a web construction, followed by selective attachment of the strands to the web at intervals. After attachment, the elongate strands may be severed at locations (218) between the points of attachment (212). The severed elongate strands may be used as fastening elements on a web backing. When used as fastening elements, the webs may be used in, e.g., garments (gowns diapers, training pants, etc .), bedding, etc . Other uses may also be envisioned for the webs with severed elongate strands, e.g., personal care products (skin debridement articles, etc.), abrasive articles, polishing articles, filters constructions (where, e.g., the severed elongate strands serve as filtering elements and/or spacers), etc.
    • 描述了位于至少一个表面上的切断的细长股线(242)的网状结构。 切断的细长股线连接到幅材(110)的一个或两个主表面,并且可以以行和列布置。 细长的股线可以通过将连续股线挤压到幅材结构上,然后间隔地选择性地将纤维束连接到幅材上而形成。 在附接之后,细长股线可以在附接点(212)之间的位置(218)处被切断。 切断的细长股线可以用作网状背衬上的紧固元件。 当用作紧固元件时,腹板可以用于例如衣服(礼服尿布,训练裤等),床上用品等。也可以设想具有切断的细长股线的幅材的其它用途,例如个人护理产品 (皮肤清创制品等),磨料制品,抛光制品,过滤器构造(例如,切断的细长股线用作过滤元件和/或间隔件)等

    • A three-dimensional highly elastic film/non-woven composite (10) having a fluid and air impervious core layer (16) and a first and second consolidated layer (12, 14). The consolidated layers (12, 14) have unidirectional and non-unidirectional fibers. The composite (10) is formed by laminating the air and fluid impermeable elastic core layer (16) between the two layers of consolidated non-wovens (12, 14). The resulting composite (10) stretches only in the cross-machine direction due to the unidirectional properties of the consolidated non-woven material. The layers are then point bonded or welded together. Preferably the layers are welded by passing the composite between an ultrasonic horn and an ultrasonic bond roll having raised areas for effecting the weld points. A thin inelastic membrane is formed at each of the weld points. The welded composite (10) may then be pre-stretched to rupture the membranes, thereby creating apertures, which makes the composite permeable.
    • 一种具有流体和不透气芯层(16)以及第一和第二固化层(12,14)的三维高弹性薄膜/非织造复合材料(10)。 固结层(12,14)具有单向和非单向纤维。 复合材料(10)通过在两层合并无纺布(12,14)之间层叠空气和流体不可渗透的弹性芯层(16)而形成。 由于固结的无纺材料的单向特性,所得到的复合材料(10)仅在横向方向上延伸。 然后将层点接合或焊接在一起。 优选地,通过使复合材料在超声波喇叭和具有用于实现焊接点的凸起区域的超声波接合辊之间进行焊接。 在每个焊接点处形成薄的非弹性膜。 焊接复合材料(10)然后可以被预拉伸以破裂膜,从而产生孔,这使得复合材料是可渗透的。
