Description

Composition for the permanent hydrophilization of polyolefin fibers and their use

The present invention relates to compositions, preferably in the form of spin finishes, for polyolefin fibers or filaments which permanently impart hydrophilic properties to these hydrophobic fibers, fibers and filaments finished with these compositions, and textile fabrics made therefrom, in particular nonwovens.

Hydrophilic nonwovens are used as cover webs, i. as the top fleece or as the intermediate fleece of multi-ply fleece, used for hygiene articles such as baby diapers, sanitary napkins, incontinence products and similar products. Such webs have the task to forward body fluids such as urine quickly to the underlying absorption layer.

Ordinary hydrophilizing preparations are washed away from the fleece more or less quickly and more or less by liquid transport within the diaper or other product. As a result, the cover fleece gradually loses its hydrophilic properties and, because of the hydrophobic properties of polyolefins, becomes more and more hydrophobic. In the subsequent further contact with body fluids their transmission to the absorption layer is more difficult and eventually impossible. The result is that the fluids leak from the nonwoven construct and that the nonwoven construct can no longer perform its original function of keeping the skin of a baby or a patient dry. On the other hand, a preparation for permanent hydrophilization should adhere to the polyolefin as permanently as possible and impart as constant a hydrophilicity as possible to the nonwoven over as long a period as possible.

Typically, the formation of a nonwoven web from filaments and / or fibers occurs, wherein random fiber webs are consolidated either by physical methods such as needling or by chemical means. In the production of carded nonwovens which are subsequently heat-set, a hydrophilizing fiber preparation additionally has to meet additional requirements. In this case, the preparation must enable the production and processing of the fibers by providing optimum sliding properties and cohesion of the fibers or filaments, as well as adequate antistatic treatment in order to be able to carry out web formation at an acceptable speed. U.S. Patent 4,988,449 discloses hydrophilizing compositions containing diethanolamides and nonionic surfactants, alkyl phosphates, quaternary ammonium salts and / or alkyl imidazolium salts, and used as liquid permeability agents for polyolefin nonwovens. No. 5,258,129 discloses hydrophilizing compositions which contain polyoxyalkylene-modified polydimethylsiloxanes, alone or in combination with nonionic surfactants, alkyl phosphates, quaternary ammonium salts and / or alkylimidazolium salts.

EP 410 485 B1 discloses a method for hydrophilicizing polyolefin-by applying an aqueous alkoxylated surfactant to the surface of the fibers, wherein the composition either at least 80% consists of alkoxylated triglycerides of C ₈ fatty acids, wherein these triglycerides a large proportion at least 80% of a mixture of alkoxylated or alkoxylated and hydrogenated ricinolein, a polyalkylene-modified water-soluble polydimethylsiloxane and an antistatic compound, the latter being, for example, a neutralized phosphoric acid ester, an alkoxylated phosphate, Potassium salt, ammonium salt or an alkoxylated ammonium salt. EP 0 839 947 A2 discloses hydrophilizing compositions which comprise nonionic surfactants in combination with a polyoxyalkylene-modified polydimethylsiloxane and / or a quaternary ammonium compound.

EP 1 600 532 B1 describes hydrophilizing compositions which consist of an alkoxylated glycerol esterified with a fatty acid and an alkoxylated or alkoxylated and hydrogenated ricinolein esterified with a fatty acid.

Although these known compositions impart permanently hydrophilic properties to the fibers and non-woven fabrics treated or finished therewith, they are however expensive to manufacture and in need of improvement with regard to Speed with which liquid is passed through the fleece in the absorption layer. Additionally, there is a need for hydrophilizing fiber and nonwoven finish compositions which are resistant to migration of dry and / or wet preparation components to adjacent nonwoven hydrophobic regions.

The invention is therefore based on the object of providing a composition with good permanent hydrophilizing properties as well as a rapid passage capability and a low tendency to migrate into adjacent hydrophobic nonwoven areas. This object is achieved according to the invention by a composition for the permanent hydrophilization of polyolefin fibers and filaments and textile fabrics produced therefrom, such as nonwovens and other nonwoven fabrics, according to claim 1.

Another pattern used was a permanently hydrophilizing fiber preparation from Schill + Seilacher GmbH, Böblingen, which is commercially available under the name Silastol ™ PHP 20 and consists essentially of a mixture of cationic antistatic agents, nonionic emulsifiers and special wetting agents.

Comparative Example 5

Comparative Example 6 As another example, a permanent hydrophilizing fiber preparation based on fatty acid polyethylene glycol esters commercially available under the name Stantex ™ S 6327 (Pulcra Chemicals) was used.

Investigation of the hydrophilizing properties

All of the preparations described above were adjusted to a dispersion with 5% by weight of active components by dilution with distilled or demineralized water. The 5% by weight active dispersion of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 6 were used as a fiber preparation for the permanent hydrophilic finish of a polypropylene (PP) spunbond nonwoven having a basis weight of 15 g / m ² . The coating weight of active substance (OPU or Oil Pick Up), based on the dry weight of the PP nonwoven, was from 0.45 to 0.65%.

To test the compositions in conjunction with said textile substrate, the tests described below were carried out.

Strike through

According to EDANA method ERT 150.2-93, the time required for 5 ml of a synthetic urine solution to penetrate a prepared fleece and to pass into the underlying absorption layer of filter paper is measured. In order to test whether the hydrophilizing equipment is washed out or is actually permanently hydrophilic, the measurement is carried out on the same nonwoven five times in succession, whereby the absorption filter paper is renewed in each case. The five readings are in seconds.

Wetback According to the EDANA method ERT 151.0-93, the quantity (in grams) becomes

Measured fluid that flows under load of a soaked fleece by a 4 kg weight in over it laid dry filter paper. Runoff test

Based on the EDANA method 152.0-99, a PP spunbond nonwoven with an inclination of 45 ° is placed on a filter paper serving as an absorption layer. It determines the run length required until a defined amount of a synthetic urine solution has been passed completely through the web into the underlying absorbent layer. To pass the test, a maximum drop length of 30 mm may be achieved.

Ten Drop Test

In the ten-drop test according to an in-house test method, a 10-well metal stencil is placed on a nonwoven piece as an absorbent layer. In each well of the metal template, one drop of a synthetic urine solution is pipetted successively. A test field counts if the amount of fluid has been absorbed within 2 seconds by the underlying absorption layer. In order to obtain information about the permanence of a fiber preparation, the test is repeated after a waiting time of 3 minutes without replacing the absorption layer. The test result indicates the number of passed test fields.

dry migration

In dry migration according to an in-house test method, migration of the hydrophilic fiber preparation components to surrounding hydrophobic nonwoven material is replicated. For this purpose, alternating hydrophilic and hydrophobic layers are layered and stored under pressure (bearing load 10 kg) at elevated temperature of 60 ° C for 48 h. The hydrophobic nonwoven layers are placed in a solution of synthetic urine and the wetting of the nonwoven layers is assessed. Ideally, no wetting of the hydrophobic nonwoven takes place. The evaluation is based on the following criteria:

Grade l: no wetting visible

Grade 2: a maximum of 5 wetting points with a diameter of <2 mm visible

Grade 3: 6 to 15 wetting sites with <2 mm diameter visible Grade 4: more than 15 wetting sites with <2 mm diameter visible, or

Wetting points with> 2 mm diameter visible

wet migration In the case of wet migration according to an in-house test method, the detachment of fiber preparation and its transfer from hydrophilic to hydrophobic areas in contact with a liquid is tested. For this purpose, a hydrophilic, equipped with a fiber preparation fleece piece is placed in a Petri dish with synthetic urine and placed a hydrophobic piece of nonwoven over it. After 30 seconds, the wetting of the hydrophobic web is assessed. Ideally, no hydrophilization of the hydrophobic web takes place. The evaluation is made by specifying the wetted surface in percent.

The results of the tests carried out for the compositions according to Examples 1 and 2 and Comparative Examples 1 to 6 are given in Table 1 below, the nominal values being compared with the respectively obtained measured values. The test is passed if all measured values lie within the range of the setpoints.

Inventive Examples 1 and 2, which contain a nonionic surfactant together with a quaternary ammonium compound and a neutralized phosphoric ester mixture, meet the requirements for rapid and permanent hydrophilization of the polyolefin nonwoven web without migration.

Comparative Examples 1 to 3 and the commercially available Comparative Examples 4 to 6, do not meet at least one of the target requirements.
