Abstract

The present invention relates to a flushable tissue or toilet tissue comprising a hydroentangled nonwoven material impregnated with a wetting composition, wherein the nonwoven material comprises cellulose pulp fibers and / or staple fibers. Non-woven material (1) contains a 2‑50mm 2 of projected surface area and aspect ratio (L / D) of 1‑10 for decomposition elements (2). The decomposing element may be selected from the group consisting of plant elements, paper containing wet strength agents, non-woven material, film material and will cause the material to decompose more easily when flushed down a sewer.

Description

technical field

[0001] The present invention relates to a flushable, hydroentangled tissue or toilet tissue impregnated with a wetting composition, wherein the nonwoven material comprises cellulose pulp fibers and / or staple fibers. Background technique

[0002] Pre-moistened paper towels or toilet paper are often used to clean different parts of the body. Examples of specific uses are baby care, hand wipes, feminine care, and toilet paper or toilet paper refill.

[0003] Because pre-moistened wipes often pass a long period of time from the time of manufacture until the time of use, they must have sufficient structural integrity during this time for their intended wiping function. Addition of wet strength agents to tissue provides such wet integrity. However, especially when used as toilet paper, it is highly desirable that the paper towel or toilet paper can be flushed down the drain without causing problems of clogging pipes and filters. Paper towels or toilet paper with...

Examples

Embodiment

[0057] Tests were carried out on a hydroentangled nonwoven material according to the invention comprising disintegrating elements in the form of calendula petals and a comparative sample containing no disintegrating elements. The samples had the following compositions.

[0058] Compared: 80wt% cellulose pulp + 10wt% lyocell fiber 12mm + 10wt% PLA: poly(lactic acid) fiber 12mm. The basis weight was 60 gsm and the material was hydro-entangled at 60 bar with 3 tubes / jet belt entangling nozzles on each side of the web with a hole diameter of 115 μm and a spacing between holes of 0.8 mm. The sample size and number of folds are suitable for samples 1-4 mentioned below.

[0059] sample 1 : 79wt% cellulose pulp + 10wt% lyocell fiber 12mm + 10wt% PLA: poly(lactic acid) fiber 12mm + 1wt% calendula petals. The basis weight was 60 gsm and the material was hydroentangled at 60 bar with 3 pipe / jet belt entangling nozzles on each side of the web. The sample size is 10x25cm, folded len...
