Problems solved by technology

Known products and prior art references address some of these requirements, but meeting all of them in a single product has proven difficult
Furthermore, it is more difficult to meet these requirements with a single product since the product can be smaller in some cases

Embodiment 1

[0075] Example 1 - Get

[0076] Tested by exposing each product to a first infusion of 5 ml of synthetic urine (9% NaCl in water) followed by a second infusion of 5 ml of synthetic urine after an interval of 10 minutes (test method no 17-28-14 ) to get properties (to get time). The results can be seen in Figure 5, which shows that for the first entry, Tena is much faster than almost all other products except Alwayspantiliners Long, and for the second entry Tena is much faster than all other products. This demonstrates that Tena's structure is perfectly capable of quickly acquiring fluids (especially urine types), thereby reducing the risk of any leaks.

Embodiment 2-D

[0077] Embodiment 2-DORUP (keep)

[0078] Retention properties were tested by ingress exposure of each product to 7 ml of liquid (synthetic urine) (see Figure 6). For more details concerning the DORUP (hold)-experiment, reference is made to US-B-6557398, which is hereby incorporated by reference. As can be seen, Tena is drier than all compared products. This demonstrates that Tena's retention properties are superior to the compared products.

Embodiment 3

[0079] Example 3 - Rothwell (Absorptive Capacity)

[0080] Test (method ISO11948-1) Rothwell value (g) (see Figure 7). Tena is shown to have an absorbency much higher than all compared pantiliners.

Abstract

Absorbent product chosen from an incontinence protection, a sanitary napkin and a panty liner, comprising a liquid permeable perforated top sheet facing the wearer during use, a liquid impermeable back sheet facing away from the wearer during use, whereby longitudinally extending textile-like edges are positioned on both longitudinal sides of the top sheet, so that a central part of the top sheet is not covered by the textile-like edges, whereby the longitudinal diameter of the apertures of the top sheet is in the interval from 0.1 to 3.2 mm, preferably from 0.5 to 3.2 mm, more preferably from 0.9 to 2.4 and most preferably from 1.6 to 2.4 mm, wherein at least 70 % of the area of the central part of the top sheet is apertured, and wherein the top sheet further comprises perforations, that are positioned between the apertures of the top sheet.; Hereby, since relatively large apertures are used, liquid is quickly let through the top sheet to the absorbent structure. Further, since small perforations are positioned between the apertures and the top sheet to a large extent is open, the acquisition properties are enhanced.

Description

technical field [0001] The present invention relates to absorbent products, in particular to incontinence guards, sanitary napkins or panty liners comprising a liquid-permeable apertured topsheet facing the wearer, a liquid-impermeable backsheet facing away from the wearer and placing The absorbent structure between the topsheet and the backsheet, and optionally the liquid distribution layer between the topsheet and the absorbent structure, wherein the topsheet and backsheet are sealed together at the periphery of the product, thereby forming edge seals, and thereby Longitudinally elongated fabric-like edges are placed on both longitudinal sides of the topsheet. Background technique [0002] In order to provide effective liquid entry in absorbent products, the characteristics of the topsheet material are important. Material selection and hydrophilic / hydrophobic properties are examples of parameters that are important to optimize a particular product and its specific purpose...
