Description
- The present invention relates to an improved multilayer for covering elements for ironing surfaces, as well as a covering element for ironing surfaces made with said improved multilayer.
- The present invention may be applied, in particular, to the manufacturing of covers for ironing boards.
- Herein, "covering element" or "cover" specifically means the element which surrounds the ironing surface (such as the upper surface of the ironing board) and on which a garment to be ironed and/or the iron is directly put, thus excluding the additional accessories which are used to be positioned between such covering element and the ironing surface and which, as a result, are not in direct contact with the garment to be ironed.
- Currently, using a multilayer consisting of an outer layer made of fabric, one or more intermediate layers of flannel or rubber, such as polyurethane foam, and a metallized inner layer for the manufacturing of covering elements for ironing surface is already known. Such a multilayer is disclosed for example in
NL1035968 - Furthermore, Italian patent
IT 1277721 - Such known solutions are not completely satisfactory, since the heat produced by the iron generates a considerable amount of moisture, which is absorbed in the covering element and stagnates therein.
- In addition, the materials currently known for manufacturing covering elements for ironing surfaces do not provide for an optimal heat reflection, thus requiring higher energy consumption as well as an increased ironing time.
- Furthermore, the known covering elements for ironing surfaces are particularly thick, which makes them particularly bulky, in particular when they are in a folded condition while not in use.
-
US 2 600 913 discloses a covering element for ironing surfaces which is intended to rapidly dissipate heat in order to avoid damages and scorches in the covering element itself. Said covering element comprises a fabric layer, the lower surface of which is sprayed with finely dispersed particles of molten metal. -
US 4 849 044 describes a covering element for ironing surfaces which is intended to show a high coefficient of heat insulation. Said covering element comprises a fabric layer, a surface of which is coated with a mixture of sticky plastic adhesives, while the opposed surface of which is sprayed with non-sticky adhesives; a layer of metal particles embedded in a matrix of synthetic resins is successively applied to one or both surface(s) of the aforesaid layer for obtaining a thermal barrier. - Such a structure does not allow to obtain a waterproof covering element and the moisture generated by ironing has the tendency to pass through said covering element and fall onto the underlying surface; moreover, such a structure does not allow to improve the smooth sliding of the iron during ironing.
-
DE 10 2010 000 379 discloses a covering element for ironing surfaces which is intended to enhance a uniform distribution of heat. Said covering element comprises an upper layer made of fabric and a lower layer consisting of a binder matrix in which mineral particles, preferably ceramic particles, are dispersed. -
DE 297 04 672 describes a covering element for a washing machine or similar household device which is heat-resistant and allows to use the upper surface of said washing machine of similar household device as an ironing surface. Said covering element comprises a layer made of fabric and a layer made of felt or foamed material, wherein one or both surface(s) of the fabric layer may be metallized. - Documents
US 2 214 824 andUS 4 360 984 , respectively, disclose further multilayer constructions of ironing pads. - None of the aforementioned documents deals with the technical problem of preventing the moisture generated by the heat generated by the iron from being absorbed in the covering element and stagnating therein.
- A main object of the present invention is to provide for an improved multilayer to be used for manufacturing a covering element for an ironing surface which allows to solve the above-mentioned drawbacks of the conventional solutions and, more particularly, avoids the undesired drawbacks related to the moisture accumulation inside the covering element. A further object of the invention is to provide for an improved multilayer to be used for manufacturing a covering element for an ironing surface which makes ironing more comfortable, easier and faster, by providing an enhanced sliding of the iron on the covering element itself.
- A further object of the invention is to provide for an improved multilayer to be used for manufacturing a covering element for an ironing surface which allows to obtain a relevant reduction of energy consumption.
- A further object of the invention is to provide for an improved multilayer to be used for manufacturing a covering element for an ironing surface which allows to obtain a covering element for an ironing surface which is easy to be folded and shows particularly reduced space requirement when folded.
- These and other objects are achieved by an improved multilayer for covering elements for ironing surfaces having the features given in the appended claims.
- According to the invention, the improved multilayer for covering elements for ironing surfaces comprises a fabric layer which is directly coupled to an underlying metallized layer, which metallized layer includes a metallic film oriented towards said fabric layer.
- Said metallized layer comprises a supporting substrate, preferably made of polymeric material, and oriented in the opposite direction with respect to said fabric layer.
- In the multilayer according to the invention, the upper surface of the fabric layer is intended to be in direct contact with the garment to be ironed and/or with the iron and the lower surface of the metallized layer is intended to be in direct contact with the upper face of the ironing surface.
- Thanks to the direct coupling between the fabric layer and the metallized layer - namely between the fabric layer and the metallic film- the improved multilayer according to the invention has several advantages:
- as it does not include any intermediate layers, it guarantees waterproofing of the multilayer itself and prevents moisture from being absorbed in the multilayer and stagnating therein;
- as it does not include any intermediate layers, it causes the metallized layer to be closer to the iron, thus allowing a higher reflection of the heat generated by the iron, which entails a shortening of the ironing time and a remarkable reduction of energy consumption;
- when using steam irons, as it does not include any intermediate layers, it causes the metallized layer to be closer to the iron and to the stream generated thereby, with the resulting formation of a kind of steam "cushion" above the fabric layer, which improves the smooth sliding movement of the iron during ironing;
- as it does not include any intermediate layers, it allows to obtain a covering element easy to be folded and having little space requirement;
- it defines an extremely even and smooth ironing plane, without necessarily requiring any additional speeding treatment (such as, for instance, silicone-based treatments);
- it allows to obtain a covering element which is also suitable to be used with irons other than steam irons.
- According to a preferred embodiment of the invention, the metallic film is continuous.
- According to the invention, the metallic film has a thickness in the range of microns.
- According to a preferred embodiment of the invention, the metallized layer is an aluminized layer.
