发明名称 Method of producing a fibrous material layer, a fibrous material layer and an absorbent article containing same
摘要 A fibrous material and a method of producing it, the material is mainly intended to be incorporated in an absorbent article and comprises a layer of continuous fibres, so-called tow, which have been bonded together in points, lines or spots in a bonding pattern, but otherwise are substantially unbonded to each other. The tow layer is bonded with at least two bonding patterns: a first relatively strong and diffuse bonding pattern, and a second more distinct second bonding pattern. 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.
