Embodiment Construction

[0039] As an embodiment, an apertured, film coating-lofty nonwoven laminate was prepared as follows: extrusion coating 0.75 mil (0.02 mm) on polypropylene / polyethylene side-by-side bicomponent nonwoven Low-density polyethylene (LDPE) film. Forming the film directly on the nonwoven gives the film a fibrous character.

[0040] The film was made from polyethylene supplied by Quantum Chemical Company (Wallingford, Connecticut) under the trade designation NA206. The film contained about 12 wt% titanium dioxide to hide mottle and reduce gloss.

[0041] The nonwoven is a 50 / 50 side-by-side conjugate fiber web available from Dow Chemical Company (Midland, MI) under the trade name Aspun  Polyethylene 6811A is supplied by Exxon Chemical Company (Houston, Texas) under the trade name Escorene  Polypropylene construction provided by PD-3445. The nonwoven has a basis weight of about 1 osy (34 gsm) and is composed of 5 denier through-air bonded, high crimp fibers produced by the spunbo...

Abstract

There is provided a cushioned absorbent material which may be used as a bodyside liner for a personal care product which is made from a lofty nonwoven fabric onto which is extruded a film to form a laminate. The laminate is then apertured and has an 8 cc intake rate of at most 20 sec and a rewet of less than 1 gm. Such a liner may be used in personal care products like diapers, training pants, feminine hygiene products, absorbent underpants, adult incontinence products, and the like.

Description

Background of the invention [0001] Cover materials for personal care articles should transfer fluid from the wearer to the underlying layers of the cover (or liner) material, where the fluid is then absorbed or distributed elsewhere. The liner material preferably has a low stain and low rewet surface to reduce liquid hold-up in the liner material itself. Microporous films are known in the art to be used as linings due to their low fouling properties and low moisture regain. However, they do not provide the softness and comfort of fibrous nonwoven materials. Accordingly, there remains a need for materials that provide the benefits of film-based liners while providing a soft and comfortable feel to the wearer. [0002] It is an object of the present invention to provide a cushioned absorbent material which can be used as a liner which is low in soiling, low in moisture regain and which is soft and comfortable to the wearer. Another object of the present invention is to make s...
