Problems solved by technology

[0004] A problem associated with pin calendering processes of the type described above is that such processes often require the use of a "carrier layer" in the pin calendering step
The use of carrier layers adds to the complexity of manufacturing
Furthermore, if the carrier layer is a layer intended to be incorporated within the final product, the incorporation of such a layer may increase the cost of the final product, and / or undesirably affect the liquid handling characteristics of the product

example

[0118] Specific inventive examples and comparative examples of the present invention are described below.

[0119] Invention Example #1

[0120] An example of a sanitary napkin according to the present invention is constructed as follows. The body-facing cover was prepared with a hot-air (HTA) bonded nonwoven material having a basis weight of 27 gsm and consisting of 100% conjugated fibers (PE / PET) available from Shalag Industries A.C.S.Ltd. ( Kibbutz Shamir, Upper Galilee, Israel) was commercially available.

[0121] A 305 gsm shaped fiber absorbent core is placed under the cover layer, the shaped fiber absorbent core combined as above Figure 1-21 The method is formed.

[0122] The absorbent core consisted of 89% by weight pulp and 11% by weight superabsorbent polymer. The pulp was Golden Isles fluff pulp 420 #HD (moisture 7%) commercially available from GP Cellulose (Brunswick, Georgia, USA). The superabsorbent polymer was Aqua Keep SA70N commercially available from ...

Abstract

The present invention generally relates to a method and apparatus for a making a formed fibrous article and more specifically to method and apparatus for making a formed fibrous article useful as an absorbent core structure in a disposable sanitary article such as a sanitary napkin, panty liner, diaper or the like. The present invention also relates to a disposable sanitary article including a formed fibrous article according to the present invention as a core structure thereof.

Description

technical field [0001] The present invention relates generally to a method and apparatus for making shaped fibrous articles, and more particularly, to making absorbent cores useful as absorbent cores in disposable hygiene articles (such as sanitary napkins, feminine hygiene pads, diapers, etc.) Method and apparatus for forming fibrous articles of structure. The present invention also relates to a disposable hygiene article comprising, as its core structure, a shaped fiber article according to the invention. Background technique [0002] Various methods for preparing shaped fibrous articles from fibrous materials such as cellulose are well known to those skilled in the art. A common method of making such shaped fibrous articles consists of defibrating the raw material and then generating an entrained flow of the defibrated material. The air-entrained defibrated material can be formed into a shaped fibrous article by using a porous mold structure and subjecting the porous mo...
