example 1

[0046] Example 1: 30wt% polyester from Kuraray Fibers, 1.7dtex / 18mm;

[0047] 70 wt% cellulose (bleached kraft pulp fiber GSM super soft plus from International Paper). The web is hydroentangled from one side. The web speed was 144 m / min.

example 2

[0048] Example 2: 30 wt% of polyester as in Example 1.

[0049] 70 wt% of cellulose as in example 1.

[0050] The web is hydroentangled from one side. The web speed was 144 m / min.

example 3

[0051] Example 3: 30 wt% of polyester as in Example 1.

[0052] 70 wt% of cellulose as in example 1.

[0053] The web is hydroentangled from one side. The web speed was 144 m / min.

[0054] Evaluations concerning strength properties and friction under wet conditions give the results in Table 1 presented below:

Abstract

A flushable moist wipe or hygiene tissue comprising 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 comprises at least two plies of the hydraulically entangled nonwoven material, each ply having a basis weight between 30 and 50 g / m2 and said plies are held together by fhctional forces without additional mechanical bonding like embossing, needling and hydroentangling and without adhesive.

Description

technical field [0001] The present invention relates to a wet wipe or sanitary tissue comprising a hydroentangled nonwoven material impregnated with a sizing composition. This particularly concerns wet toilet paper and other wipes or sanitary tissues that are intended to be flushed down the drain. Background technique [0002] Pre-moistened wipes or sanitary tissues are commonly used to clean various parts of the body. Examples of specific uses are for baby care, hand wipes, feminine care and as toilet paper or as a supplement to toilet paper. [0003] Since a long period of time often elapses between the time of production of a pre-moistened wipe and the point of use, the wipe must have sufficient structural integrity for its intended wiping action over this period of time. Adding a wet strength agent to the wipe will provide the wet integrity. However, particularly when used as toilet paper, it is highly desirable that the wipes or tissues be able to be flushed down the...
