Problems solved by technology

Another concurrent disadvantage is that the adhesive that is not in contact with the backsheet will not transfer from the release paper, making the use of the absorbent article more difficult because the release paper can now stick to undesired surfaces, making the absorbent article The attachment complication of
Also, applying adhesive directly to the backsheet will not be able to apply the adhesive to the valleys formed in the backsheet, causing the same problems as release paper

[0089] sample preparation

[0090] Sample testing is performed at room temperature and standard pressure and humidity.

[0091] Samples were prepared as described herein. Specifically, these samples are Maxi Pads, which are embossed before being attached to a polypropylene backsheet. Will Maxi Pad embossed on Figure 19 The embossed areas are shown so that the body facing surface (topsheet) has an average side embossing depth of 5.5 mm and an average end depth of 2.7. The garment-facing surface (backsheet) of the Maxi Pad had an average side recessed area depth of 2.6mm and an average end recessed depth of 2.8mm.

[0092] For contact application of adhesive to release paper - use the EP11 slot applicator (Nordson Corp. (Westlake, OH)) to apply the adhesive 34-689B, available from National Starch & Chemical Co. (Bridgewater, NJ) in the shape of two 18 mm wide rectangles in an amount of 15 grams per square meter (gsm) at temperatures between 155°C and 160°C The patt...

Abstract

An embossed article having one or more adhesive patterns serving to operatively attach a release paper. A method for attaching a release paper to a backsheet having depressed regions.

Description

technical field [0001] The present invention relates to an embossed absorbent article having an adhesively adhered release paper. The invention also relates to a method for embossing an absorbent article and applying adhesive to the absorbent article. Background technique [0002] Rotary embossing systems have traditionally been used to emboss webs forming absorbent articles. A typical embossing system includes a rotating embossing roll and a cooperating rotating anvil roll. Different embossing dies can be affixed to the rotating embossing roll to produce a variety of desired embossing patterns for absorbent articles. A typical embossed absorbent article, such as a feminine hygiene napkin, comprises a topsheet, an absorbent core and a backsheet, the backsheet usually being attached to the topsheet prior to embossing the topsheet and absorbent core. Attaching the backsheet to the absorbent core prior to embossing limits the embossing depth because during embossing, if the ...
