The nonwoven fabrics used here, due to the random or statistical arrangement of fibers in the nonwoven material, which give excellent strength in all directions, do not tend to tear or disintegrate when used, for example, in a household tumble dryer. Examples of non-woven fabrics which are suitable as substrates in the present invention are known, for example, from WO 93/23603. Preferred porous and flat conditioning wipes consist of one or different fiber materials, in particular cotton, refined cotton, polyamide, polyester or mixtures of these. The conditioning substrates in cloth form preferably have an area of 0.2 to 0.005 m ² , preferably 0.15 to 0.01 m ² , in particular 0.1 to 0.03 cm ² and particularly preferably 0.09 to 0, 06 m ² . The grammage of the material is usually between 20 and 500 g / m ² , preferably from 25 to 200 g / m ² , in particular from 30 to 100 g / m ² and particularly preferably from 40 to 80 g / m ² .

The fourth object of the invention is a conditioning method for conditioning moist textiles by means of the conditioning substrate according to the invention.

The conditioning process is carried out by the inventive Conditioning substrate together with moist textiles, which for example consist of a previous washing processes originate, used in a textile drying process becomes. The textile drying process usually takes place in a device for Drying textiles, preferably in a household clothes dryer instead.

The fifth object of the invention is therefore the use of the invention Means and / or the conditioning substrates according to the invention for reducing the Linting of textile fabric. Another subject is the use of the Agents according to the invention and / or the conditioning substrates according to the invention for Reduction of pilling of textile fabric.

Lint occurs when fibers break on textile surfaces. In one Household dryers with fluff filters then find the fiber fragments again. The Fiber particles are transported to the fluff filter by the air flow. The pill formation is similar. Pills are more or less spherical structures that are formed by anchor fibers are connected to the fabric and whose density is such that no light penetrates and a shadow is cast. This change can affect both Washing process as well as occur during use. Pills are formed when there are Work fibers out of a textile fabric and tie them together in use. Such surface changes are undesirable. In general, the degree of Pill formation determined by the speed of the following parallel processes: a) fiber entanglement, which leads to pill formation; b) emergence of others Surface fibers and c) abrasion of fibers and pills.

Examples

Conditioning agents according to the invention are, for example, E1 and E2, a comparison recipe is V1, the compositions of which are shown in Table 1. Table 1

The formulations E1 to E4 were made by melting the ester quat in water manufactured. The melted ester quat is then with a stirred highly dispersing device and added the remaining active substances. The Perfume was added after the mixture had cooled to below 30 ° C.

Nonwovens made from cellulose were used to produce conditioning substrates according to the invention (Area: 24.5 cm × 39 cm) each with 20 g of one of the invention Conditioner E1 to E4 soaked. A comparison substrate with the Recipe V1 produced.

Lint formation and pill formation

There are 3.5 kg of dry laundry consisting of 6 terry towels, 8 pillows, 5 tea towels, 2 m white 100% CO woven goods (shirts quality), 2 m white 100% PES microfiber woven fabric, 2 m white 100% PES microfiber jersey, 50 cm white 50% CO / 50% PES poplin fabric, 2 m white 100% CO single jersey and 2 Underpants with tower powder at 30 ° C in an automatic washing machine (Miele Novotronic W 985; Normal wash program 30 ° C) washed and then dried in one Household clothes dryer (Miele Electronic T 352 C; cupboard dry, easy to clean).

After the drying process, the previously tared fluff filter becomes the household dryer balanced.

• a) die Textilien wurde ohne Konditioniersubstrat getrocknet
• b) die Textilien wurden mit einem Konditioniersubstrat V1 in den Haushaltstrockner gegeben
• c) die Textilien wurden mit einem Konditioniersubstrat E1 in den Haushaltstrockner gegeben
• d) die Textilien wurden mit einem Konditioniersubstrat E2 in den Haushaltstrockner gegeben
• e) die Textilien wurden mit einem Konditioniersubstrat E3 in den Haushaltstrockner gegeben
• f) die Textilien wurden mit einem Konditioniersubstrat E4 in den Haushaltstrockner gegeben

The washing-drying-weighing cycles were repeated 10 times under the following conditions:

• a) the textiles were dried without a conditioning substrate
• b) the textiles were placed in the domestic dryer with a conditioning substrate V1
• c) the textiles were placed in the household dryer with a conditioning substrate E1
• d) the textiles were placed in the household dryer with a conditioning substrate E2
• e) the textiles were placed in the household dryer with a conditioning substrate E3
• f) the textiles were placed in the household dryer with a conditioning substrate E4

The weight of the fluff was determined after each drying cycle and over the 10th Cycles added. It was found for a) 7.58 g, for b) 8.39 g, c) 4.05 g, d) 5.51 g, e) 4.17 and f) 6.21 g.

By using the conditioning substrates according to the invention, the Lint formation is considerably reduced and the textiles are spared.

Under the same conditions as listed above, studies on the Pill formation performed. The investigations were carried out in accordance with DIN EN ISO 12945 Part 2 "Determination of the tendency of textile fabrics to form lint on the Surface and the pill tendency "with the help of a Martindale scouring and pilling Test device model 404 performed. The investigations were carried out in the climatic room (Textile climate 20 ° C, 65% relative humidity). The principle of Martindale-Testes is the test subject against a defined tissue in one constantly changing motion which ensures that the surface fibers samples are bent in all directions. The resulting pills on the The surface of the test objects is visualized according to a defined number of tours Comparison against a standard set. The abrasive discs with one Diameters of 140 mm are clamped over the chafing tables, underlaid through standard felt disks. The test specimens (diameter 140 mm) are in special sample holders fixed and placed with the right side to the counter textile. The Guide plate of the device is attached above, and loaded with weights Spindles are inserted through the guide plate into the sample holder below introduced. The drive mechanism consists of two outer and one inner Drive that forces the guide plate of the sample holder to close a Lissajous figure describe. The Lissajous movement changes to a circular movement to itself gradually narrowing ellipses until it becomes a straight line from which progresses Develop expanding ellipses in a diagonally opposite direction before the pattern is repeated.

The degree of pill is determined by the test subject against prepared photographs of Standard goods is compared.

The measurement showed that the pill formation of the textiles with the Conditioning substrates c), d), e) and f) according to the invention in comparison to the samples from a) and b) is significantly reduced.

Comparable results were observed when 36 ml of the invention Conditioning agent in the rinse chamber of an automatic washing machine in the rinse cycle be applied to the textiles to be conditioned. The one with the not Textiles treated according to formulation V1 according to the invention showed a significantly higher Lint and pill formation.
