Problems solved by technology

However, such absorbent pads are relatively expensive to produce
[0007] Additionally, absorbent pads commonly used today do not include deodorants, antimicrobial components, or fragrances, so their use is often unpleasant both for the user and for those nearby.

Embodiment Construction

[0034] Figure 1-5 Example of

[0035] figure 1 A production line is schematically illustrated, generally indicated at 10, for the manufacture of absorbent pads according to the invention. according to figure 1 The absorbent pad is manufactured in figure 2 described in.

[0036] Depend on figure 1 Manufactured on line 10 in and in figure 2 The absorbent pad shown in is a three-layer pad comprising a lower porous layer 2, a middle layer 3 of absorbent powdered pulp, and an upper porous layer 4. As will be described in more detail below, figure 1 and 2 The three-layer absorbent pad in can be used alone, or it can be used as a core for making absorbent pads with more than three layers, e.g. Figure 6 and 7 Five layers of absorbent pads in .

[0037] thus, figure 1 The production line 10 shown in includes a fabric (web) 12 that passes through a plurality of stations to which different materials are applied and processed to manufacture figure 2 The three-laye...

Abstract

The invention refers to a method of making an absorbent pad, and the absorbent pad so made, including a porous under layer and an absorbent body including a pulverized pulp and a super-absorbent materials bonded to and between the porous layers; characterized in that the absorbent body is applied between the porous layers before bonding thereto by: applying a first layer of pulverized pulp to the porous under layer; applying a layer of the super-absorbent material over the first layer of pulverized pulp; and applying a second layer of the pulverized pulp over the super-absorbent material layers. One or more of the above layers also includes a deodorizer material which may include a deodorizer agent, to reduce odors, an anti-inflammatory agent to prevent skin erythema, and / or a perfume fragrance.

Description

[0001] related application [0002] This application is a continuation-in-part of US Patent Application Serial No. 12 / 149,159 filed April 28, 2008, and claims priority from that US Patent Application. technical field [0003] The present invention relates to a method of making an absorbent pad, and also to an absorbent pad made by such a method. Background technique [0004] Absorbent pads, sometimes called pantiliners, have a wide variety of uses including: medical use, for wound care and hospital pads; feminine hygiene products, such as tampons, panty liners; children's and adult diapers; food packaging, such as Permeable pads for meat and fish packaging; and industrial filtration, e.g. for kerosene, hydraulic oil, etc. [0005] Absorbent pads generally comprise a porous lower layer, a porous upper layer and an absorbent body comprising a powdered slurry and superabsorbent material bonded to and disposed between the two porous layers. The two porous layers are usually m...
