Description

TECHNICAL PART

The present invention relates to a process for the production of an ironing cloth according to the preamble of the independent main claim as well as the thus obtained ironing cloth.

DESCRIPTION OF THE PRIOR ART

Generic ironing cloths build on a heat-resistant, inert fabric to provide a surface extended ironing surface. An ironing cloth is for ironing of underwired on an ironing pad - preferably an ironing board - placed and forms with its surface, the heat-resistant, inert ironing surface. The underwire is placed on the ironing surface and ironed with a hot, smooth surface - such as an iron.

The heat resistance of the fabric is designed in such a way that the heat stress caused by an iron lying on the upper side does not damage the fabric. This ensures suitability for pressure-enhanced, slow ironing of coarse cotton fabrics.

Inert refers to fabrics which are also during slow, pressure-reinforced ironing against adjacent fabrics and fabrics capable of no reaction and thus can not cause changes in colors and stabilities of the goods to be ironed.

From the DE 297 04 672 U1 For example, a garment in the form of a heat-resistant textile cover is known, wherein the textile cover is designed as a cover for household white appliances.

The problem with ironing cloths is that the heat and heat radiation introduced with the iron in the case of open fabric structures extends far into the fabric of the ironing cloth penetrates and convection is discharged uncontrollably over hot air flows. The resulting, uneven temperature distribution leads to uneven smoothing of the ironing. In completely closed, top-sealed fabric structures, however, there is heat build-up directly on the surface, which means that even small pleats in the underwire can lead to a damaging, punctual heat maximum. This leads to the contradictory requirements to distribute the applied heat on the one hand as controlled and evenly as possible, on the other hand to avoid temperature fluctuations - as they always occur in the distribution - as possible.

In view of this problem, the DE 297 04 672 to equip the ironing cloth with a metallised surface. The metallization provides a heat-reflecting layer which avoids uncontrolled, convective heat leakage. However, the problem of convective heat build-up on the surface is disregarded. Therefore, care must be taken, especially with coarse materials that are to be hot-ironed, to ensure a smooth surface over the entire surface in order to avoid damaging heat maxima.

In the same way they reveal JP 020 11 200 . DE 19 064 29 and also the CH 3 36 047 for the regulation of the heat radiation, the application or introduction of a heat-reflecting layer in the form of metallic or mineral particles. The heat-reflecting layer, preferably supported in a continuous resin layer, will both conduct heat back and preferably will not allow any water vapor to pass. Especially when hot ironing with steam support so the loss of heat introduced is minimized. Also the GB 6 64 345 as well as the US 3,911,603 A disclose mixtures of heat-reflecting particles which are to be introduced into an ironing pad via continuous - preferably watertight - layers of polymer and / or resin.

The known, optimized ironing pads according to the prior art have in common that although they minimize heat loss, but do not take into account the problem of heat build-up along the surface. Optimally designed underwires according to the prior art thus save energy, but already at the slightest overheating lead to heat accumulation with damaging heat maxima in the ironing and ironing surface arranged underwired.

Object of the present invention, therefore, was to overcome the disadvantages of the prior art and to provide a temple cloth, which in terms of heat accumulation and Thermal guidance during ironing provides improved user-friendliness and allows easier ironing of the ironing fabric.

The solution of this object is achieved according to the features of the independent claims. Advantageous embodiments will become apparent from the dependent claims and the following description.

SUMMARY OF THE INVENTION AND ADVANTAGEOUS CHARACTERISTICS

According to the invention, a pressing cloth 1, which builds up on a heat-resistant, inert fabric 2, along the ironing surface on a thermal release layer 5 with mineral particles. In use, the fabric 2 forms the upper side of the ironing surface, while the bottom 4 of the ironing cloth 1 on a hanger pad - for example, an ironing board - rests.

Mineral particles are derived from mineral metal compounds which are inert and heat resistant and have a theoretical density greater than 1 gram per cubic centimeter relative to the particular compound.

The thermal separation layer 5 contains the above-described mineral particles. This particulate layer has a combination of higher, structural density, low thermal conductivity and increased heat capacity in the individual particles relative to the tissue. In combination with the high surface area resulting from the particulate structure, a layer is achieved which stores heat almost completely within the volume of the layer and returns it convectively as well as in the form of heat radiation.

The inventors believe that combined heat storage and return will result in a more uniform distribution of iron heat which may explain the observed improved usability and reduced tendency to crease and wrinkle.

Preferably, the mineral particles are selected from compounds of metals with non-metals. Metal-non-metal compounds have a better thermal separation effect and a reduced proportion of heat loss.

The particles are particularly preferably of a ceramic nature and have oxidic, silicate or salt-like structures. Ceramic structures contain no water-soluble components and are particularly stable. Particles of such nature gave better heat resistance and longer life expectancy of the thermal barrier coating during pressure-loaded, hot ironing of coarse cotton fabrics.

Preferably, the mineral particles are at least partially arranged in a binder matrix. A matrix is a structured spatial form in which the particles are distributed with controlled density. With increasing particle density, the thermal separation effect increases, while with increasing particle spacing, the uniformity of the heat distribution can be improved.

Preferably, by supporting the particles via a binder matrix, a density gradient, which increases towards the bottom, of particles with decreasing particle spacing is set. As a result, impinging heat in the upper regions of the thermal barrier layer is initially distributed convectively and reflectively more uniformly, while in the lower regions, the storage and the return reflection of the heat take place more strongly with increasing particle density and decreasing particle spacing. About this model can be explained with so designed, thermal separation layer 5, advantageously lower tendency for thermal damage of sensitive materials.
Particularly preferably, the particles are supported on fabric fibers and the fabric fibers in turn along the fabric 2 with increasing fiber density incorporated into the cloth. This type of particle introduction allows specific control of the particle density, can be done via mechanical weaving and spinning processes and requires no additional, costly measures in the production. Consequently, the tissue itself can advantageously also function as matrix and / or binder.

Preferably, the thermal separation layer 5 is at least partially formed of volcanic rock particles. Volcanic rocks were created in extreme heat and were exposed to the weather for centuries. Due to the weather, the soluble components were flushed out of the structure of the volcanic rock. This explains the low proportion of water-soluble constituents, the predominantly ceramic structure and high heat resistance. As a result, volcanic rocks are particularly inert, but at the same time also have continuous cavities and gaps, as a result of which heat storage and distribution are improved particularly advantageously in the ironing cloth according to the invention. The inventors make the combination of the above-described properties for the observed, superior, thermal effect and advantageous resistance of volcanic rocks in a thermal separation layer 5 responsible.

According to the invention, the thermal separation layer 5 is at least partially formed of porous particles. Porosity is caused by pores with diameters in the micrometer range. Such pores have an increased, capillary suction effect and absorb moisture from the surrounding air much faster. In this case, heat can additionally be stored / delivered. The improved thermal uniformity of porous particulate separation layers 5 is attributed to this mechanism by the inventors.

Particularly preferably, the thermal separation layer has particles with 30% to 70% open porosity, at least over a horizontally continuous layer volume. Such a layer exhibited a significantly improved uniformity of heat distribution and moisture penetration of the ironing fabric when steam ironing with increased humidity.

Preferably, the ironing cloth 1 on the underside of the fabric 2, an elastic fabric layer 6 - preferably a foam layer, particularly preferably tulle by the meter, - on. The elastic fabric is characterized by high elasticity at low density. The preferred foam is a foamed, heat-resistant plastic cellular structure and low density. The particularly preferred tulle by the meter is, for example, designed as a mesh, characterized by a very large-celled, air-permeable structure of lowest density, which can be adjusted by regulated gathering advantageous in their elasticity.

In the present case, an improved resistance of the ironing cloth 1 and of the thermal separating layer 5 could be ascertained with a heat-resistant, elastic fabric layer 6 as part of the underside structure of the ironing fabric 1. The inventors attribute this to the more uniform pressure distribution in force-pressing ironing: A more even pressure distribution with resilient pad can - especially when ironing laundry with buttons and protruding applications - to avoid the harmful, punctual pressure load. As a result, the thermal separation layer 5 is exposed to lower voltages, which is able to explain the increased resistance without contradiction.

Preferably, the elastic fabric layer 6 is at least partially open. An open fabric layer 6 is characterized by a structure in which at least a part of a cell structure interconnected continuously allows the all-round entry and exit of ambient air. In steam ironing processes, such a structured elastic material allowed the removal of excess water vapor; The water vapor was subsequently released again from the substance. As a result, the air-permeable fabric layer resulted in lower water consumption with longer residence time of the steam within the ironing pad. The steam ironing itself was also considerably simplified, since the longer residence time of the steam resulted in a more uniform moisture and easier ironing behavior.

Particularly preferred as a proportionally open formed fabric layer 6 is an at least two-layer combination of ruffled tulle by the meter and bottom side abutting molton layer used. In this case, an improved slip resistance of a layered fabric 1 was achieved by both sides of the masticated molton and at the same time found a surprisingly improved breathability. The inventors attribute this to the sequence of very large-meshed, air-permeable Tüllware and significantly denser, superficially roughened fabric layer: on the one hand air flows increasingly between the fabric 2 and molton and on and is heated more evenly. On the other hand, the dense molten material provides a deformable only with much greater pressure layer. Due to the hard elasticity, the full-area installation of the iron is clearly perceptible even with strong pressure during ironing, whereby the ironing easier and the risk of damage is reduced by excessive pressure forces.

Preferably, the underside 4 is at least partially formed as a diffusion-open polymer film. A vapor-permeable polymer film is permeable to water in the gaseous state, but is able to retain water in the liquid state. In particular, when steam ironing with intensive water entry so designed underside prevents the breakthrough and the uncontrolled drainage of water and thereby also reduces water consumption. Such a configuration is particularly preferably combined with a proportionately open fabric layer 6-in particular an open-porous foam layer-whereby the effective use of water vapor during ironing is additionally increased.

Particularly preferably, the underside 4 is at least partially formed as a diffusion-open polyester film. Polyester polymer films can be applied particularly simply by melting / laminating on the underside of the thermal release layer 5 on an ironing cloth. As a water-vapor-permeable polymer film such a bottom polyester film prevents the uncontrolled drainage of condensation, particularly cost, makes sure, however, that the ironing cloth is able to dry completely even after a steam ironing.

According to the invention, the ironing cloth 1 is produced by a process comprising the steps

1. a) Provision of sub-millimeter-sized, mineral particles
2. b) homogenizing mixing of the mineral particles with a binder to form a particle-binder mixture

Here, submillimeter large, mineral particles are presented in step a).

These particles preferably have a maximum particle size of 0.5 millimeters and a broad particle size distribution. The broad particle size distribution allows for later, advantageous classification, whereby density and spacing gradients can be adjusted. Most preferably, the particulate mixture is provided by repetitive milling and sieving of porous volcanic rock. Porous volcanic rock breaks easily to produce a broad particle size distribution, is advantageously inert and provides by separation through a sieve with a mesh size of 0.5 mm and repeated grinding of the larger fractions in a particularly simple and energy-saving way an advantageous mixture of mineral particles predominantly ceramic nature.

Synthetic, porous, ceramic precursor compounds provide co-treated particulate blends with precisely predictable properties. Particular preference is given to using a particle mixture of volcanic rock and synthetic, ceramic compounds, in particular a predominantly ceramic particle mixture.

In step b) a homogeneous particle-binder mixture is produced. Preferably, a fiber is used as a binder, which is / are easily integrated into the fabric. Particular preference is given to using a liquid or molten binder, in the particles are suspended. A molten binder additionally offers the advantage that the binder, which is rigid at room temperature, permanently fixes a particle distribution which has been set once in the molten state.

In step c), the particle-binder mixture is applied to a heat-resistant, inert cotton fabric 2 on the underside. A cotton fabric is based on particularly heat-resistant cotton threads, which allow a particularly strong and durable attachment of the particles due to their fibrous surface structure. In the case of fibrous binders, the application can even take place via a particularly simple integration of the fibrous portions into the fabric fibers of the cotton threads. Advantageously, in the case of liquid and / or molten binders, a space distribution of the binder is predefined via the fabric structure in the lower area, which predetermines a gradient of particle-binder mixture, for example via tapered and decreasing vertical thread spaces.

The use of liquid or molten binders particularly preferably allows the suspension to be preliminarily classified by vibration, whereby finely divided fractions accumulate on the underside, while coarse fractions rise up. In this way, a planar binder-particle layer can advantageously be pre-classified before being introduced into the tissue in order to additionally advantageously set a density gradient of the particles within the thermal separation layer.

In step d), the binder is solidified and the particle distribution within the thermal barrier layer is permanently fixed. Advantageously, a liquid binder in this case simultaneously serve as an adhesive or connector for adjacent layers - particularly preferably for an elastic material layer and / or diffusion-open polymer film.

Further advantages emerge from the exemplary embodiments. It is understood that the above-described features and advantages and subsequent embodiments are not restrictive. Advantageous, additional features and additional combinations of features, as described in the description, can be realized in the context of the independent claims in the claimed garment both singly and deviating combined, without departing from the scope of the invention.

DETAILED EXPLANATION OF THE INVENTION BY HAND OF EXAMPLES

Fig. 1 1 illustrates an embodiment of an ironing fabric 1 in which a thermal release layer 5 is applied to the underside on a heat-resistant, inert fabric 2. This embodiment is of a particularly simple structure and provides an ironing cloth which can be applied to provide a stirrup surface on suitable surfaces of household appliances as well as ironing surfaces to take advantage of the thermal release layer 5.

Particularly advantageous for the use of the ironing cloth 1 as a cover or ironing board cover for longitudinally extending surfaces with similar width but varying length, a pure cotton fabric is used, which is formed as a knitted fabric with increased transverse elasticity. Knitwear of increased transverse elasticity, more preferably knitted fabrics of circular knitting machines, provide directional elasticity through the thread guide within the fabric, reflecting the basic elasticity of the loops laid in loops. Thus, such fabrics are essentially elastic alone transversely to the direction of action, without the need for separate measures. Transverse elasticities of up to 100% are advantageously accessible. The use of pure cotton threads in such a structure in the transverse direction to the longitudinal extent of the ironing surface thus advantageously provides a fabric which can adapt elastically to the varying length.

It is understood that the advantage described above can be applied in the same direction in example in the width varying ironing board series by longitudinal alignment of the direction of action. The improved cross-elasticity of knitwear, by aligning it in parallel with the manufacturer's variation of ironing board dimensions, provides a surprisingly versatile fabric that is adaptable to varying dimensions.

In combination with pure cotton threads a fabric 2 is achieved, in which a particularly resistant anchoring of the particles of the thermal barrier layer on the surface-rich fibers of the cotton threads is possible. By supporting the particles on the respective threads, the transverse elasticity of the knitwear is advantageously preserved.

• In einem ersten Schritt c1) wird zunächst eine Partikel-Binder-Suspension mit einem aktivierten reaktiv-Binder oberflächlich auf die Fläche eines Stoffes - bevorzugt über einen Spachtel oder ein Messer - aufgetragen.

Particularly advantageous in the production of a two-stage application of the particles has proven on cotton fabrics:

• In a first step c1), a particle binder suspension with an activated reactive binder is first applied superficially to the surface of a substance, preferably via a spatula or a knife.

An activated reactive binder here denotes a binder which sets in air contact and / or after addition of a starter within a predetermined time. By heating, the curing time can be shortened accordingly. Such binders particularly advantageously permit the mechanical, controlled application of a particle layer.

As a result of the thin, superficial application, particles are first introduced into the fabric 2 individually and in small agglomerates, and subsequently form a multiplicity of solid binder bridges on the fibers of the respective threads.

In a second step c2), a thicker layer of particle binder suspension - advantageously with activated reactive binder - is drawn off under pressure on the pretreated tissue surface. In this case, the ratio of binder to particle amount is small, so that the particles are enveloped solely by a continuous binder layer. The particles form agglomerates which have contact points with the threads, the already anchored particles and one another. By curing under alternating transverse stress - preferably by guiding tissue webs over several roles - the agglomerates are each anchored in particular thread-like manner over the previously generated binder bridges in the tissue. Here, the agglomerates have a continuous degree of voiding of at least 10%, whereby an all-round inflow and outflow of gases is facilitated. such even an optically continuous, opaque particle layer for gases is always open to diffusion, so that even with increased water vapor load in ironing equipment, a liquid accumulation can not occur.

An advantageously configured layer in an arrangement as in FIG. 1 illustrated, on a transversely oriented to the longitudinal direction of an ironing surface tissue high transverse elasticity, provides an ironing fabric that can be particularly advantageous as ironing board cover elastically adapted to different lengths ironing surfaces and brings all the benefits of the thermal release layer 5 in a particularly advantageous combination.

Fig. 2 illustrates an ironing cloth 1 with heat-resistant fabric 2 with incorporated therein, thermal release layer 5 and the lower side applied, elastic fabric layer 6. By introducing the release layer 5 in the structure of the fabric 2, a temple cloth is achieved in which the particles of the thermal release layer 5 advantageously stable anchored within the tissue volume. By controlled, one-sided introduction, a particularly advantageous, to the surface decreasing particle density within the tissue volume can be adjusted, which brings convective heat distribution, heat storage and heat recovery during ironing particularly effective and advantageous combined to bear.

By an underside arranged to the fabric 2, elastic fabric layer 6 while a pressure load during ironing is distributed more evenly. The elastic material layer 6 is preferably a gas-permeable substance on all sides. Due to the pressure load during ironing, part of the contained, free gas volume will flow through the thermal separation layer 5 up to the ironing surface. In this case, the upflowing gas is heated by the heat stored in the separating layer and thereby contributes to the more uniform heat distribution advantageous.

Particularly preferably, a tulle fabric with a knitted, flat network structure is used as elastic fabric layer 6. Such a tulle material is characterized by a net-like structure with a large mesh size, in the advantageous as under Fig. 1 above a transverse elasticity is structurally predetermined. By transverse gathering of such a Tüllstoffbahn in adjacent loops and folds the transverse elasticity is also effectively introduced over the thickness of the fabric layer 6. Such a fabric layer 6 has an extremely low density, very good gas permeability and high structural elasticity. This promotes the Gas permeability with the least amount of material advantageous the effect of the thermal release layer. 5

Particularly preferred is such Tüllstoffbahn with an advantageous, transversely elastic fabric 2 as under FIG. 1 is described combined. Here, by the same direction orientation of the weave structure of fabric layer 6 and fabric 2 a directionally equal, unidirectional elasticity in the entire structure of the ironing fabric 1 is achieved in which no destructive tensions between fabric 2 and fabric layer 6 can occur even with the strongest strains; such an arrangement proved to be superior resilient and resistant.

Particularly preferred in the production as a resilient fabric layer 6 is a Quergeraffter polyester Tüllstoff used with mesh structure, which previously coated on the upper side with a liquid hot melt adhesive and / or binder in the ironing cloth 1 is integrated. The polyester is able to fuse / react with a reactive binder / hot melt adhesive surface, so that during the brushing area extended contact areas are formed on the threads of Tüllstoffes. In the subsequent shirring / laying arise at all wetted with binder contact and support points binder bridges with advantageous flat, stable bridge base.

Fig. 3 1 illustrates a heat-resistant fabric 2 ironing fabric 1 in which the thermal release layer 5 extends into both the upper-side, heat-resistant fabric 2 and the lower-side elastic fabric layer 6 and firmly bonds the two structures 2, 6 together. A so structured hanger 1 brings the under FIGS. 1 and 2 as well as being superior in handling and durability. The inventors attribute this back to the transition regions of the thermal separation layer 5 present here. The reaching into fabric 2 and fabric 6, thermal barrier layer 5 sets through the transition areas significantly more uniform temperature gradients. On the one hand, the more uniform temperature gradients can bring about a better thermal separation of fabric layer 6, fabric 2 and ironing surface while, on the other hand, provide a longer path over which the gases are heated / cooled in the case of outgoing and incoming gases. Combined with the heat stored in the particles, this improves the uniformity of the heat distribution, which can explain the superior handleability.

Particularly advantageous is an embodiment as shown in FIG. 3 is illustrated as an ironing board cover using a transverse elastic fabric 2 and one on one transversely elastic Tüllstoff constituting fabric layer 6 according to the advantageous combination according to the description of FIG. 2 educated. A thus formed ironing board cover has superior handleability, high ironing comfort and improved durability. The thread-like support and bonding of fabric 2, fabric layer 6 and particles of the thermal release layer 5 via a liquid reactive binder and / or thermosetting thermoset leads to a one-piece, superior ironing cloth 1, which is stress-free and improved in its structure over a plurality of connection points with binder bridges stabilized while providing improved heat transfer during ironing.

Preferably, an embodiment of the ironing cloth 1 is provided as an ironing board cover with at least one elastic twist-elastic, over which the available ironing surface superior upper side part is on the underside raffbar.

In a particularly advantageous use of an ironing board cover formed as ironing cloth 1 is additionally a dense fabric layer with a maximum density of 200 grams per square meter, more preferably a molten, previously pulled under the ironing board cover and with at least one cable - preferably with pulled in drawstrings in the fabric cable , in particular a train consisting of a solid cord or of an elastic drawstring, in particular an elastic band - tightened and additionally fixes the ironing cloth; Especially with a surface difference between ironing surface and ironing cloth of more than 50% can ensure a firm, smooth fit of the ironing cloth on an ironing board on a double roughened fabric layer, wherein the uniformity of the thermal release layer 5 is surprisingly reinforced.

Particularly advantageously, an ironing cloth 1 designed as an elongated ironing board cover has a series of longitudinal slots centrally on its longitudinal extent on both outer edges, which are arranged on the underside of the ironing board in an applied position, which make it possible to operate a lower-side locking mechanism of the ironing board legs. By executing a lever of the said locking mechanism through one of the longitudinal slots, a continuous, uniform contact of the ironing cloth 1 is ensured on the underside of the ironing board and slipping and warping is additionally prevented.

• In einem ersten Schritt a1) wurde ein zumindest querelastisches Gewirke - bevorzugt ein Jersey-Stoff - bestehend aus reiner Baumwolle, vorbereitend mit einem oberflächenaktiven Gleitmittel gewaschen. Das oberflächenaktive Gleitmittel - bevorzugt ein silikonartiges Gleitmittel auf Basis eines Silikon-Tensids - zieht auf den Baumwollfasern auf, separiert diese und senkt zudem die Oberflächenspannung des Wassers. Dadurch wird eine vollständige Durchdringung des Gewirkes mit Flüssigkeit sichergestellt. Zusätzlich werden die Fäden des Gewirkes oberflächlich geschmeidiger und können besser gleiten, wodurch die Querelastizität verbessert und stabilisiert wird. Besonders bevorzugt wird das so vorbereitete, vollständig einmal durchtränkte Gewebe anschließend noch eingefärbt. Nun wurden (a2)) submillimeter große, mineralische Partikel bereitgestellt und (b)) mit einem Binder unter Erzeugung einer Partikel-Binder-Mischung homogenisierend vermischt.

Another embodiment was made as follows:

• In a first step a1) was an at least transversely elastic knitted fabric - preferably a jersey fabric - consisting of pure cotton, preparatory with a surface-active Washed with a lubricant. The surface-active lubricant - preferably a silicon-based lubricant based on a silicone surfactant - absorbs on the cotton fibers, separates them and also lowers the surface tension of the water. This ensures complete penetration of the fabric with liquid. In addition, the threads of the knit become smoother on the surface and can slide better, thereby improving and stabilizing the transverse elasticity. Particularly preferably, the tissue prepared in this way, which has been thoroughly saturated once, is subsequently dyed. Now, (a2)) submillimeter-sized mineral particles were provided and (b)) homogenously mixed with a binder to form a particle-binder mixture.

In a second step c1), a first, thin layer of the particle-binder mixture with a wiping edge was first applied to the surface of the prepared, transversely elastic knitted fabric and dried. Due to the thin, flat application to the surface activated by the lubricant particles spread finely distributed individually and in small agglomerates in the fabric 2 and form during the drying of a variety of solid binder bridges with a broad base.

In a third step c2), a thicker layer of particle-binder mixture was applied to the pretreated fabric surface on the underside and in a fourth step c3) as fabric layer 6 a transversely gathered, transversely elastic tulle by the meter - preferably consisting of 100% polyester fibers - placed in the same direction to the tissue aligned web structure on the underside of the fabric.

In a fifth step d), the laid-up, cross-lapped tulle fabric was hot-laminated with a hot roller under pressure and the layer of the particle-binder mixture was cured in intimate contact with fabric, binder bridges and tulle by the meter. By guiding the fabric web over the hot roll, the binder bridges are each connected thread-wise under continuously changing transverse tension firmly with the tulle by the meter at contact points. The previously produced binder bridges are connected in the fabric and through the additional hardening layer with the tulle by the meter. By the same direction alignment of tissue and tulle-piece goods a directionally equal, unidirectional elasticity in the entire structure of the ironing cloth 1 is achieved in which no destructive tensions between fabric 2 and fabric layer 6 can occur even with the strongest strains.

In a sixth step, an ironing cloth 1 with a longitudinal extent becomes parallel to the unidirectional fabric 2 with a thermal release layer 5 on the underside Dominant elasticity formed, the side edges are folded on the bottom side, fixed and provided with an elastic rubber surround - preferably with an elastic band.

Claims (9)

1. A method of producing an ironing cloth (1), wherein the ironing cloth (1) comprises a heat-resistant inert fabric (2) having a topside (3), which forms the ironing surface, and an underside (4), which rests on an ironing support, and the ironing cloth (1) comprises along the ironing surface a thermal separating layer (5) comprising mineral particles, characterized in that the method comprises the steps of

   a) providing mineral porous particles of submillimetre size,

   b) homogenizingly mixing the mineral particles with a binder to produce a particle-binder mixture,

   c) undersidedly applying the particle-binder mixture to a heat-resistant inert cotton fabric (2),

   d) consolidating the binder to produce an undersided thermal separating layer (5) comprising porous absorbent particles,

   to obtain an ironing cloth (1) in which the thermal separating layer (5) consists at least partly of porous particles wherein pores having diameters in the micrometre region have been formed to have an enhanced capillary sucking effect on moisture in the ambient air.
2. An ironing cloth according to the preceding claim, characterized in that the mineral particles are selected from compounds of metals with non-metals, more preferably comprising one or more than one compound comprising one or more than one substance class from the group consisting of ceramic oxides, silicates and salts.
3. An ironing cloth according to either preceding claim, characterized in that the mineral particles are at least partly disposed in a binder matrix.
4. An ironing cloth according to any preceding claim, characterized in that the thermal separating layer (5) is formed at least partly of volcanic rock particles.
5. An ironing cloth according to any preceding claim, characterized in that the thermal separating layer (5) consists at least partly of particles having 30% to 70% open porosity.
6. An ironing cloth according to any preceding claim, characterized in that the ironing cloth comprises an elastic layer (6), preferably a foamed layer, more preferably tulle as yarded goods, undersidedly in relation to fabric (2).
7. An ironing cloth according to the preceding claim, characterized in that the elastic layer (6) is formed to be at least in part openly porous.
8. An ironing cloth according to any preceding claim, characterized in that the underside (4) is formed as an at least partly breathable polymeric sheet, preferably as a polyester sheet.
9. An ironing cloth according to any preceding claim, characterized in that the ironing cloth is formed as a longitudinally extended ironing board cover,
   comprises a heat-resistant inert fabric (2), a topside (3), which forms the ironing surface, and an underside (4), which rests on an ironing support,
   wherein the fabric (2) is formed as a jersey fabric, preferably knitted from 100% cotton with a transverse elasticity of up to 100%, preferably 30 to 70%, and its knitting direction is disposed transverse to the longitudinal extent of the ironing board cover and the fabric comprises a surficially supported lubricant, preferably a surfactant compound based on silicone,
   in that the ironing cloth (1) comprises undersidedly along the ironing surface a thermal separating layer (5) secured via a cured, liquid binder and consisting of dustly fine mineral porous particles, preferably consisting of ceramic particles up to 0.05 millimetres in size,
   wherein the particles are absorbently secured, individually and in agglomerates, separately, via a binder, to the threads of the fabric (2), wherein further the agglomerates consist of particles surficially bonded together, at their mutual points of contact, via binder bridges, and have an intercommunicatingly connected voidage amounting to not less than 10% by volume,
   in that the ironing cloth (1) comprises an elastic layer (6) undersidedly in relation to the fabric (2),
   wherein the elastic layer (6) is formed as an airy tulle fabric - preferably of 100% polyester - gathered into pleats and fixed to the fabric (2) and having a knitted planar meshed structure with codirectional alignment of the knitting direction and codirectional transverse elasticity,
   wherein in turn the fixing of the elastic layer at the contact points of the folds to the fabric underside is effected via the binder of the particles of the thermal separating layer (5), and
   in that an elastic rubber band is disposed in the outer edge of the ironing cloth (1) to run around therein, wherein preferably there is appositionally disposed on the underside to the elastic layer (6) a molleton undercover consisting of 100% polyester, having an areal density of 200 grams per square metre, 5% smaller area and at least one drawstring running in drawstring casings in the fabric, in particular a drawstring consisting of a firm cord or of an elastic drawband, in particular a rubber drawband.
