Embodiment Construction

[0128] In order to compare products made with the absorbent fibrous webs described herein, different materials suitable for hand wiping were compared.

[0129] The following samples were compared:

[0130] Sample A:

[0131] Foam formed and hydroentangled absorbent fibrous web material as described herein. Gram weight 45.5gsm. Fibres were 15% viscose, commercial 1.7dtex 10mm Danufil, Kelheim and 85% unrefined bleached softwood kraft pulp. The material also adopts 80 dots / cm 2 The pattern is micro-embossed. See Figure 1a and 1b ,in Figure 1a showing the side towards the hydroentangled jet, Figure 1b The side facing the hydroentangled fabric is shown. The hydroentanglement was carried out at 294 kWh / t at a machine speed of 10 m / min.

[0132] Sample B:

[0133] Foam formed and hydroentangled absorbent fibrous web material as described herein. Gram weight 58.8gsm. The fibers were 17% viscose, 0.9dtex 8mm commercial Danufel, Kelheim and 83% RaumaCellBiobright TCF (f...

Abstract

The invention relates to an absorbent fibrous web wherein the fibers consist of cellulosic fibers comprising cellulosic staple fibers and cellulosic pulp fibers, the absorbent fibrous web being a spunlaced entangled fibrous web formed from a foam. The invention also relates to a method for producing such an absorbent fibrous web.

Description

technical field [0001] The present invention relates to an absorbent fibrous web and a method of making such an absorbent fibrous web. Background technique [0002] Absorbent fibrous webs can be used in the manufacture of hygiene and wiping products. Hygiene and wiping products are typically manufactured by cutting the absorbent web into sheets or by rolling the absorbent web into rolls suitable for the end user. Sometimes, two or more absorbent fibrous webs are combined into a single product, whereby the absorbent fibrous webs form the layers of the combined product. Thus, the layers can be connected to each other by embossing and / or adhesive. In addition, one or more absorbent fibrous webs can be used as one or more layers in a sanitary absorbent article for absorbing bodily fluids, such as panty liners, sanitary napkins, incontinence articles, or diapers. [0003] Typical properties of these hygiene and wiping products include their ability to absorb tensile stress ene...
