Zusammenfassung: | A fibrous material and a method of producing it, said material is mainly intended to be 5 incorporated in an absorbent article and comprising a layer of continuous fibres, so- called tow, which have been bonded together in points, lines or spots in a bonding pattern (10), but otherwise are substantially unbonded to each other. The tow layer (15) is bonded with at least two bonding patterns: a first relatively strong and diffuse bonding pattern (lOa), and a second more distinct second bonding pattern (lOb). Bonding of at least the first bonding pattern takes place by thermobonding, wherein a pattern roll is used which provide the desired bonding patterns. In the first welding step the pattern roll is driven at a higher speed than the feeding speed of the tow layer, so as to create a relatively diffuse and strong bonding pattern (lOa). |
