摘要： The present invention relates to a hygiene article comprising an effective odour control system, wherein essential oils, an organic zinc salt such a zinc ricinoleate, and preferably a chelating agent and/or a physical agent interact synergistically to reduce malodours of bodily fluids. The present invention is of particular importance to the field of hygiene products, in particular feminine hygiene absorbent articles (sanitary napkins, panty liners).

摘要： The current invention concerns a method and apparatus for stretching and repitching an elastic member for attachment to a moving substrate, the elastic member being stretchable in at least a longitudinal direction and said elastic member in an essential non-stretched condition comprising an initial length along said longitudinal direction, the method comprising the steps of: (1) providing the elastic member in essentially non-stretched condition to a set of repitching members with an initial supply pitch, said set of repitching members comprising at least a first repitching member and a second repitching member, and optionally one or more repitching members arranged between said first and said second repitching member; (2) receiving said elastic members arranged in non-stretched condition between said set of repitching members, whereby the distance between the first and the second repitching member corresponds to the initial length of the elastic member; (3) moving at least said first and said second repitching members following trajectories diverging from each other, thereby stretching said elastic members arranged between the repitching members to an application length which is longer than the initial length and which corresponds to the length of said elastic member in elastically stretched condition, whereby said repitching members are moved with selectively variable velocity when transferring said elastic members to selectively vary the application pitch of said elastic member in stretched condition on said substrate, the variation of the speed of said repitching members determining the application pitch of said elastic member in stretched condition on said substrate, characterized in that during step (3), said set of elastic members are rotated around a common rotation axis while the elastic member is being stretched from the initial length to the application length. Additionally, the invention concerns a method and apparatus for stretching and repitching an elastic member for attachment to a moving substrate whereby the elastic members are held by repitching members, which are rotated at an essentially constant rotational speed around rotation axes in trajectories, said trajectories being defined by having a different radial distance from the rotation axis to the repitching member rotating around said rotation axis at the application position where the elastic member is attached to the substrate, than at the initial position where the elastic member is received by the repitching members, thereby changing the pitch of the elastic members.

摘要： The current invention concerns an improved method for intermittently providing strips of a continuous first web material onto a continuous second web material, in particular a method for manufacturing tampon blanks, in a continuous process, thus avoiding the disadvantages of stop-and-go methods. Furthermore, an apparatus or system is provided for executing said methods.

摘要： A system and method for tearing off and rolling up a strip of absorbent fiber sheet for a tampon are discussed. An endless absorbent fiber sheet is propagated with a first linear speed by a first pair of rolls, and with at least the first linear speed by a second pair of rolls. A pulling means is provided to induce a second linear speed in the sheet larger than the first linear speed for tearing off a strip from the sheet. The first pair of rolls is configured to maintain the first linear speed of the absorbent fiber sheet, while the second pair of rolls is configured to rotate in a freewheel-type manner when the absorbent fiber sheet is pulled through the second pair of rolls at linear speeds larger than the first linear speed. Preferably, the pulling means is a rotatable clamping means for rolling up the strip.

摘要： An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

摘要： An absorbent core for an absorbent article, the absorbent core comprising at least two layers, each layer having a width w and a length l along a first plane and a thickness t extending perpendicular thereto, wherein the layers are arranged in facing relationship along the first plane, and wherein the layers comprise a polymeric foam having an open cell and interconnected porous structure. The first and second layers comprise an anisotropic cell structure having an axis of anisotropy extending substantially parallel to a longest length of a plurality of substantially neighbouring cells. The axis of anisotropy of the second layer extends substantially perpendicular to said thickness t and parallel to said first plane and the axis of anisotropy of the first layer is substantially perpendicular to the axis of anisotropy of the second layer.
