IRONING CLOTH

The innovation concerns an ironing cloth, in particular an ironing cloth made from natural raw materials.

It is well known that when ironing with steam or dry, you need to use a surface that has a certain elasticity. In the simplest case, folded wool blankets were used, which the housewife spread out on a table, for example.

Over time, the use of ironing boards became common, which were placed on a table, but in more recent times were equipped with their own collapsible legs. These ironing boards had a more or less pronounced taper at one end, which usually ended in a curve, and at the other end a frame made of metal wire on which the hot iron was placed when it was not in use. The ironing board itself was covered with a fabric cover, which had an elastic, flexible material on its underside, and the ironing cloth was finally cut to the shape of the ironing board, provided with a band around it and a hemstitch through which a cord was pulled, which made it possible to stretch the ironing cloth on the ironing board and in this way also secured the ironing cloth to the ironing board so that

Since the ironing cloth and ironing board now more or less form a unit, and are usually sold as such, the ironing cloth is also called an ironing board cover.

This ironing cloth generally consists of a textile product in the broadest sense, which is coated on one side with a stronger, thicker layer or layer of a foamed plastic. In addition, a coating is applied to the surface of the textile product that forms the working surface, which consists of a spreadable plastic pigmented with fine metal particles, usually aluminum particles.

This metal-containing surface coating is intended to smooth the surface and the metal particles are intended to reflect heat onto the side of the item to be ironed that faces the surface of the ironing cloth. In some cases, the ironing cloth is also perforated with small holes at larger or smaller intervals.

As advantageous as the coating of the textile product may be for certain physical phenomena that occur during ironing, it cannot be ignored that the heat from the iron on the plastic and on the metal particles in conjunction with the ironing movement causes abrasion, a decomposition of the plastic to a certain extent with the release of ingredients, depending on the manner in which the plastic was applied.

In addition, the positive properties inherent in the textile fabric cannot develop due to the covering with the plastic layer, especially since a plastic of more or less high density and impermeability is also applied to the opposite side. In practice, therefore, an ironing process only takes place on a plastic surface, which

is smooth, but otherwise has few desirable properties. When wet ironing, the steam will essentially build up in the item being ironed and wet it heavily, as the steam can practically not escape downwards. These negative characteristics of the ironing cloth in general use today need to be overcome.

The innovation therefore proposes an ironing cloth which comprises a cotton textile in plain or twill weave, which has a padding layer on one side which consists of a fleece made of cotton, rayon or viscose fibers and both are connected to each other by a binding agent. The top layer of the ironing cloth, which consists of untreated cotton, is suitable as it is as an ironing surface on which the item to be ironed is placed. The ironing cloth according to the innovation is therefore permeable to gas, air and steam on all sides, which promotes the ironing process because heat or moisture cannot build up anywhere in the area below the item to be ironed.

Through the ironing process, the surface of the cotton textile is quickly subjected to a process that is equivalent to or similar to "mercerization" of the cotton, in that the surface of the ironing cloth is smoothed and solidified, but still retains the required fine porosity.

The actual ironing cloth can be connected to the padding in a variety of ways, including by using a binding agent, e.g. a very thin film made of polyurethane that is flamed, after which both layers of the ironing cloth are connected to one another. For this type of connection, which is called "flame lamination", a thin film made of PU foam is used, which, however, does not need to be labelled in accordance with the TKG (Textile Labelling Act) because

its quantity is less than that laid down by the law on labelling. In the present case, this quantity is less than 5% by weight of the entire textile.

The connection of both layers of the ironing cloth, namely the cotton textile in plain or twill weave and the nonwoven fabric, can also be done by sewing or needling.

According to the innovation, as already shown above, the ironing cloth is bordered on its edge by a band, which is known as a hemstitch on an ironing cloth. Since a cord is pulled into the hemstitch, with which the ironing cloth is stretched onto the ironing board, tension is also exerted on both the upper textile layer that forms the ironing surface and the padding underneath, so that both layers are held firmly together, because the cord or band that runs through the hemstitch all the way around is used to stretch the ironing cloth onto the ironing board.

The new ironing cloth is therefore made of a natural material with the advantages listed above, it does not require an additional coating and therefore no abrasion or environmentally harmful gases and vapors can be produced and the ironing process is promoted by using the natural properties inherent in cotton.

The innovation is now explained using the drawing, which shows a cross-section through an ironing cloth in accordance with the innovation.

In the only figure in the drawing, reference number 1 designates the upper layer of the ironing cloth made of an untreated cotton textile in twill or plain weave, reference number 2 designates the padding layer underneath, also made of cotton, rayon or viscose, with a thickness of around 4 mm to 5 mm. Reference number 3 is intended to identify the connection between the two textiles, provided that this is done by means of the aforementioned flame lamination.

Alternatively, the connection can also be made by sewing, needles or stitching, as indicated by the dashed lines on the edge at 4. This is where the binding tape 5 is sewn on, which also contains the cord or tape (not shown in the drawing) with which the ironing cloth is tightened to the ironing board in the usual manner.

The edging band 5 is also made of cotton, so that the entire ironing cloth is now made of materials that have similar, if not identical, behaviors and properties in or during the ironing process.

Protection claims

Claims (3)

PROTECTION CLAIMS 1. Ironing cloth, in particular ironing cloth for an ironing board, characterized in that a textile (1) made of cotton in plain or twill weave carries on one side a padding layer (2) which consists of a fleece and both are connected to one another by a binding agent. 2. Ironing cloth according to claim 1, characterized in that the connection of the textile (1) with the padding layer (2) is made by flame lamination or by sewing, needling or quilting. 3. Ironing cloth according to claim 1 and 2, characterized in that it is bordered by a band (5) which is also made of cotton in plain or twill weave and surrounds the edge of the ironing cloth in a U-shape and forms a hemstitch through which a band for fastening the ironing cloth to the ironing board is pulled.
