Embodiment

[0039] figure 1 A bond pattern 100 for a nonwoven is shown having thermal bonds comprising different sizes and orientations. figure 1 is shown on a 1:1 scale, while figure 2 Close-up view shown at 5:1 scale. The nonwoven extends in the machine direction (MD) and in the perpendicular cross direction (CD). This bonding pattern is discussed below for purposes of illustration. The illustrated designs may of course be modified applying the general considerations above. For example, in Figure 1-Figure 2 In the example of , the individual area of ​​the larger bonds 110, 120 is 3.2mm 2 , and the individual area of ​​the smaller bonds 130, 140 is 0.36mm 2 , and there are twice as many smaller bonds than larger bonds, but either of these values ​​can be modified applying the aforementioned ranges. The larger bonds on the one hand and the smaller bonds on the other hand may all have the same individual area as shown. Of course, it is not excluded that the larger bond and / or the...

Abstract

The present invention provides nonwoven extending in a machine direction (MD) and a perpendicular cross-machine direction (CD) and having fibers bonded by a pattern of thermal bonds (100). The thermalbonds comprise larger bonds (110, 120) having an individual area of at least 1.0 mm<2>, in particular at least 1.5 mm<2>; and smaller bonds (130, 140) having an individual area of less than 1.0 mm<2>, in particular from 0.10 mm<2> to 1.0 mm<2>. There are at least as many smaller bonds as larger bonds, the ratio of the number of smaller bonds may be in particular about two.

Description

technical field [0001] The present invention relates to improved thermal bond patterns for fibers of nonwovens. Nonwovens may in particular be used as topsheets or backsheets in absorbent articles such as taped diapers, diaper pants or pantiliners. Background technique [0002] Absorbent articles for personal hygiene of the type described above are designed to absorb and contain body exudates, in particular large quantities of urine. These absorbent articles comprise several layers, typically a topsheet on the wearer-facing side, a backsheet on the garment-facing side with an absorbent core in between, and other layers. An acquisition and / or distribution layer may further be provided between the absorbent core and the topsheet. Topsheets are typically made from nonwovens or formed films. The backsheet is usually made of a fluid-impermeable plastic film, sometimes double-layered on its outer side by a nonwoven layer to provide a better feel. It is known to consolidate non...
