The method includes the steps of: providing an absorbent article converting line; supplying a first material web to the converting line; supplying a second material web to the converting line; printing a first colored region on at least one of the first material web or the second material web using contact printing at a contact printing station; and printing a second colored region on at least one of the first material web or the second material web using non-contact printing at a non-contact printing station. The first colored region has an arcuate shape.

Nonwoven fabrics suitable for a wide variety of applications (e.g., healthcare, filtration, industrial, packaging, etc.) are provided. In one aspect, the nonwoven fabric includes a plurality of segmented fibers. Each of the plurality of segmented fibers may comprise a fiber axis and a plurality of alternating larger diameter and smaller diameter segments along the fiber axis. The plurality of segmented fibers may be substantially aligned in a first direction.

A lamination system includes a sheet supply, a material supply, and a laminator. The laminator causes a sheet from the sheet supply to be laminated to a sheet from the material supply to establish a laminated sheet.

A process for making an elastomeric laminated product including the steps of laminating an elastomeric film between a first spunbond nonvowen layer and a second spunbond nonwoven layer so as to form a laminated web, transporting the laminated web through intermeshing rollers so as to strain portions of the laminated web to form activated regions in the laminated web, and transporting the activated laminated web to a first portion of a rotating wheel, the first portion of the wheel having a cross direction width that is smaller than a cross direction width at a second portion of the wheel, so that the laminated web follows rotation of the wheel and is stretched in the cross direction at the second portion of the wheel before separating from the wheel at the first portion in a relaxed state.

A method of forming a disposable hygiene product includes providing a manufacturing line (10) having a back sheet station (12), a core layer station (14) and a top sheet station (16) connected by a conveying system (18), providing a back sheet (20) at the back sheet station, providing a core layer (22) at the core layer station, applying the core layer on the back sheet, providing a top sheet (24) at the top sheet station, and applying the top sheet on the back sheet and core layer. The back sheet station includes a fluid application device (28) configured to discharge a curtain of material to form a polymer film (201), and the back sheet includes the polymer film.
