Description

TEXTILE BAND FOR INTRODUCTIVE MACHINES, DRYERS

AND CLOTHING IRONERS

DESCRIPTION

Technical Field of the Invention

The present invention corresponds to the technical field of introducers, dryers and ironers of clothes, applicable to wall machines and calenders in general, specifically to the textile band used in this type of machines on which the clothes to be ironed, dried or fold and which is formed by at least two layers of textile fibers. These can be made of aramid, polyester or other similar material that has a high resistance to the high temperatures used in this type of process.

Background of the Invention

At present there are different types of introducers, dryers and ironers for industrial use, the most widespread being flat, murals and calenders, which in all cases use textile bands that are well responsible for exercising the surface of the treaty of the garment, either of transporting said garments to be treated according to one of these processes, inside the machine, pressing them against heating rollers that have a high temperature to ensure a correct finish of the same.

As these textile bands are going to suffer a continuous exposure to the high temperatures of the process, they need to be made of materials resistant to them, and therefore, they are usually formed by at least two layers of heat-resistant textile fibers, usually consisting of a layer of Aramid, which will be the one in contact with the parts of the machine that are at high temperatures and, another polyester, which withstands somewhat lower temperatures but is not in contact with these hot areas.

During the process of introduction, drying and ironing in this type of industrial machines the temperatures reached are usually higher than supported by the polyester layer, especially in the machines of wall type and calenders, although although in those of flat type the temperature is somewhat lower, the bands are continuously exposed to them.

Although the layer in contact with the pieces that are at a high temperature is the aramid layer, it is not capable of exerting a thermal barrier that serves as a protection to the polyester layer, with which the latter can suffer deformations and deterioration of the same that forces its replacement, with the consequent maintenance expense.

This is the most frequent problem at present, that the continued use of the textile band at a high temperature, generate degradations in the polyester layer, which undergoes elongations, deformations or stretches that make it necessary to replace the band with the consequent increase of the maintenance cost, since its duration is limited.

Description of the invention

The textile band for introducers, dryers and ironers of clothes applicable to wall machines and calenders in general, of those formed by one or more superimposed textile layers presented here, comprises a first layer in contact with the clothes, formed by aramid fibers resistant to the high temperatures of the process, at least a second layer that is not in contact with the clothes, formed by synthetic polyester fibers and an intermediate layer formed by a fiberglass mesh adhered to the inner face of two of the possible layers of existing aramid and synthetic polyester fibers.

It also comprises means of adhesion of said fiberglass mesh to the other two layers of aramid fibers and polyester synthetic, these means being resistant to the high temperatures of the process.

These adhesion means are formed by a silicone adhesive that is placed on both sides of said intermediate layer, in order to be able to adhere on each of its faces one of the fiber layers to the glass fabric.

As the adhesive is also going to be exposed to the high temperatures of the process, of the order of 240 ⁵ C, it must be formed by this type of silicone polymer, resistant to them, that is, it withstands temperatures of the order of 280 ⁵ C keeping its characteristics intact. The first layer of aramid fiber that will be in contact with the clothes and therefore subject to very high temperatures, can withstand temperatures higher than the order of 220/240 ⁵ C that are reached in the process.

The second layer of polyester synthetic fiber, which is not in contact with clothing, is subject to somewhat lower temperatures, thanks to the presence of the intermediate fiberglass layer that can withstand temperatures of the order of 1000 ⁵ C.

With the improved textile band for drying and ironing machines proposed here, significant improvements are achieved with respect to the state of the art.

Thus, with the proposed band, and thanks to the existence of the intermediate layer of glass fabric resistant to temperatures much higher than those reached during the process, the band itself is stable and more resistant to high temperatures.

This is so thanks to the fact that the thermal barrier function that the aramid layer itself performed in another type of textile bands of the state of the art, is achieved here with this intermediate fiberglass layer that resists temperatures much higher than those generated in the process, so it is a much more efficient thermal barrier than aramid in addition to having a much lower cost.

By effectively acting as a thermal barrier, it is possible to avoid deformations and deterioration of the polyester layer that is the most sensitive of all at high temperatures, as well as of the band itself that does not suffer elongations or stretches, thus reducing the need to replace it, with the consequent savings in terms of maintenance.

Brief description of the drawings

In order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, a series of drawings are provided as an integral part of said description where, for illustrative and non-limiting purposes, represented the following: Figure 1 .- Shows a view of the section of the textile band, with all the layers that form it in the preferred example of the proposed invention.

Detailed description of a preferred embodiment of the invention

In view of the figure provided, it can be seen how, in a preferred embodiment of the invention, the textile band (4) for clothes introducers, dryers and ironers applicable to wall machines and calenders in general, of those formed by one or more overlapping textile layers, which are proposed here include three layers.

As can be seen in Figure 1, the first layer (1) which is the one in contact with the clothes and therefore more exposed to high temperatures by contact with the heating parts of the machine is formed by resistant aramid fiber at high process temperatures, in particular with a resistance to temperatures exceeding the order of 220/240 ⁵ C.

It also includes a second layer (2) that is not in contact with the clothing, formed by synthetic polyester fiber.

And an intermediate layer (3) formed by a fiberglass mesh adhered to the inner face of the two previous layers of aramid fiber and polyester synthetic.

This intermediate layer (3) of fiberglass has a temperature resistance such that it can withstand temperatures of the order of 1000 ⁵ C so that it acts as a thermal barrier (3) for the second existing layer (2) of fiber Polyester, which is not in contact with clothing and which has lower resistance to high temperatures than the first layer.

This textile band (4) also has adhesion means of the intermediate mesh (3) of fiberglass to the first and second layers of aramid fiber and polyester synthetic respectively.

The adhesion means, in this preferred example of the invention are formed by an adhesive (5) placed on both sides of the intermediate fiberglass mesh (3) to adhere to each of them, the first and second layers of textile fiber respectively. This adhesive (5) is also subjected to the high temperatures of the process, whereby a polymer resistant to them is chosen, in particular silicone, which can withstand the order of 280 ⁵ C.

With the textile band applicable to ironing, drying and folding machines presented here, improvements are obtained that eliminate the inconveniences existing in the state of the art.

In this way, the intermediate fiberglass layer incorporated into the textile band acts as a thermal barrier thanks to its high resistance to the high temperatures reached during the process.

With this material as a thermal barrier, a greater resistance to the high temperatures of the textile band is achieved, which therefore does not suffer deformations or stretches, whereby substitutions and repairs are reduced, reducing maintenance costs.

On the other hand, to this we must add the lower cost obtained when using a fiberglass mesh as a thermal barrier instead of the materials used in the state of the art, such as the novelty consisting of a layer of silicone rubber or rely on the aramid fiber layer itself, in both cases the cost is much higher, in addition to the low effectiveness of this last option with the aramid fiber layer, in which deformations do occur and the deterioration of the polyester layer
