Benefits of technology
The present invention provides a moist wipe or hygiene tissue that is strong enough for its intended use but can be easily dispersed in a sewage system. This is achieved by using a hydraulically entangled nonwoven material that contains pulp fibers and manmade or natural fibers with a length of at least 6 mm. The material has at least two plies that are held together by frictional forces without any additional mechanical bonding like embossing, needling, and hydroentangling, as well as adhesive.
Problems solved by technology
Wipes or tissues having a high wet strength will not disintegrate or break up into small fibre clumps when flushed in conventional household toilet systems, which may cause plugging of the drainage system.
They can move along drainage and sewage pipes, but are not readily dispersible and may therefore cause problems with blocked pipes and filters.

[0043]Test materials were produced as described below. A fiber dispersion was made from water and a mixture of pulp fibres and manmade staple length fibres. The fibrous web was hydroentangled from one side. The fibrous web was then dewatered by vacuum suction boxes and dried by through-air-drying technique. The fibres used for forming the fibrous web had the following composition:
Ex. 1
[0044]30 wt % polyester from Kuraray Fibers, 1.7 dtex / 18 mm;
[0045]70 wt % cellulose (bleached sulphate pulp fibres GSM supersoft plus from International Paper). The web was hydroentangled from one side. The web speed was 144 m / min.
Ex. 2
[0046]30 wt % polyester as in Example 1.
[0047]70 wt % cellulose as in Example 1.
[0048]The web was hydroentangled from one side. The web speed was 144 m / min.
Ex. 3
[0049]30 wt % polyester as in Example 1;
[0050]70 wt % cellulose as in Example 1.
[0051]The web was hydroentangled from one sides. The web speed was 144 m / min.

Abstract
A flushable moist wipe or hygiene tissue includes a hydraulically entangled nonwoven material impregnated with a wetting composition. The nonwoven material contains at least 70%, by fibre weight, pulp fibres and at least 5%, by fibre weight, manmade fibres and / or natural fibres with a length of at least 6 mm. The moist wipe or hygiene tissue includes at least two plies of the hydraulically entangled nonwoven material, each ply having a basis weight between 30 and 50 g / m2, and the plies are held together by frictional forces without additional mechanical bonding like embossing, needling and hydroentangling and without adhesive.
Description
FIELD OF THE INVENTION[0001]The present invention refers to a moist wipe or hygiene tissue comprising a hydraulically entangled nonwoven material impregnated with a wetting composition. It is especially related to moist toilet paper and other wipes or hygiene tissue intended to be flushable in a sewer.TECHNICAL BACKGROUND[0002]Pre-moistened wipes or hygiene tissue, are commonly used for cleansing different parts of the human body. Examples of specific uses are for baby care, hand wiping, feminine care and as toilet paper or as a complement to toilet paper.[0003]Since a long period of time often elapses from the time of manufacture of pre-moistened wipes until the time of use, they must have sufficient structural integrity for their intended wiping function during such period. Adding a wet strength agent to the wipe will provide such wet integrity. However, especially when used as toilet paper, there is a strong desire that the wipe or tissue can be flushed in the sewer without causi...
