A patterned layer is intended to be used in an absorbent article, and has a pattern, for example in the form of a text or an image, which appears clearly legible or interpretable for an observer at a certain distance. The pattern can be formed by a number of dots which, when the layer is in a first state, have a first surface density which forms the legible or interpretable pattern and which, when the layer is in a second and then expanded state, have a second surface density which is lower than the first surface density in the first state, the pattern becoming in the second state essentially illegible or uninterpretable for the observer at the given distance on account of the lower surface density.

Method of making a patterned layer for absorbent article

An elasticized web has a gatherable substrate and a multi-strand elastic yarn affixed to the gatherable substrate at a plurality of fixation locations. So that the yarn can be affixed to the substrate without the use of an adhesive, the yarn is subjected to forces to create partial delamination of the yarn at the fixation locations and a portion of the gatherable substrate is caused to pass between the thus delaminated strands of the multi-strand elastic yarn. The elasticized web of the present invention is particularly suitable for use in disposable absorbent articles.

Elasticized web and a method and apparatus for its manufacture

The present invention relates to a method for production of a three-dimensional dyed macropattern in a web of web-shaped flexible material. The method comprises a bonding device being made, in interaction with the dye-coated tops of the raised macroportions, to form bonding points and three-dimensional bonding areas at the same time as the bonding areas and/or the bonding points are dyed, thereby forming a three-dimensional dyed macropattern.
