Another purpose of the present invention is to achieve a machine for treating fabrics that can offer the widest guarantees of reliability and safety during use.

A further object of the present invention is to realise a machine for treating fabrics which is both easy to implement and economically competitive compared to the prior art.

The above task, as well as the aims and other tasks that will be set forth in more detail below, are achieved by a machine for treating fabrics, in particular for dip-dyeing fabrics in rope form, as claimed in claim 1.

Other envisaged features are set forth in the appended claims.

Further characteristics and advantages will become more apparent from the description of a preferred, but not exclusive, embodiment for treating fabrics, in particular for dip-dyeing a fabric rope dyeing machine, which is illustrated by way of non-limiting example in the accompanying drawings. Wherein:

figure 1 is a schematic cross-sectional view of a machine for treating fabrics according to an example of the invention.

Figure 2 shows three variants of the machine for treating fabrics shown in figure 1.

With reference to the above illustrations, a machine for fabric treatment, in particular for dip dyeing rope fabric dyeing machines, indicated as a whole with arabic numerals, comprises:

a treatment drum 3 for treating the fabric rope 5 with a treatment liquid 7.

Motorized roller 9, called reel, arranged in the upper part of the treatment drum 3 and adapted to support and pull the fabric in rope form 5 along a closed treatment path;

a first tubular body 11 comprising a first end 110 substantially arranged on the motorized roller 9 and a second end 112 arranged inside the treatment drum 3.

The fabric in rope form 5 is pulled by the motorized roller 9 along the first tubular body 11.

The first tubular body 11 comprises at least one nozzle 13, which nozzle 13 is adapted to dispense the treatment liquid 7 on the rope fabric 5 inside the first tubular body 11.

The treatment liquid 7 ejected from the second end 112 of the first tubular body 11 is collected in the lower part of the treatment drum 3 according to the invention.

According to the invention, the first tubular body 11, located in the lower part of the nozzle 13, comprises a U-shaped portion 111, the U-shaped portion 111 being or being siphon-shaped, suitable for being at least partially filled with the treatment liquid 7, so that the fabric rope 5 drawn along the U-shaped portion 111 is immersed in the treatment liquid 7 inside the U-shaped portion 111, the U-shaped portion 111 of the first tubular body 11 having the advantage of exerting a mechanical deformation on the fabric rope 5 drawn along the closed treatment path by the motorized roller 9.

In essence, the rope fabric 5 is also subjected to cyclic mechanical deformation of the U-shaped portion 111 in the pulling along the U-shaped portion 111 of the first pipe body 11.

More precisely, in the descending section of the U-shaped portion 111 the fabric rope 5 is subjected to mechanical stretching, whereas in the ascending section of the U-shaped portion 111 the fabric rope 5 is subjected to mechanical compression.

Advantageously, the machine 1 comprises a second tubular body 12, which second tubular body 12 connects the treatment cylinder 3 with the motorized roller 9, inside which second tubular body 12 the fabric in rope form 5 pulled by the motorized roller 9 slides after leaving the treatment cylinder 3.

Advantageously, the machine 1 comprises a cross-lapping device 15 arranged at the outlet at the second end 112 of the first tubular body 11 and adapted to fold the fabric in rope form 5 at the outlet of the first tubular body 11.

Advantageously, inside the treatment drum 3 there is a perforated basket 17 suitable for containing the fabric rope 5 coming out of the cross-lapping device 15, where the fabric rope 5 is compacted by folding.

Advantageously, the perforated basket 17 can be at least partially immersed in a tank 19 of treatment liquid 7. In this case, the folded fabric rope 5, which is also stored compressed inside the perforated basket 17, can therefore be at least partially immersed in the tank 19 with the treatment liquid 7.

The treatment liquid 7 in the tank 19 in the treatment drum 3 is distributed by the nozzles 13 into the first tubular body 11 and is sprayed into the treatment drum 3 at its outlet.

Advantageously, the machine 1 comprises a pump, for example a centrifugal pump, adapted to circulate the treatment liquid 7 between the tank 19 present in the treatment drum 3 and the nozzles 13.

Thus, a continuous flow of treatment liquid 7 from the nozzle 13 along the first tubular body 11 and up to the bottom of the treatment drum 3 is facilitated and collected in the tank 19 where this treatment liquid 7 accumulates. It is supplied again to the nozzle 13 by a pump.

It is also advantageous that the machine 1 is circular, i.e. its treatment drum 3 has a substantially circular cross-section, or has a shape such as a compressed fabric, a so-called J-box.

The tubular body 11 may comprise, in addition to those defined by the U-shaped portion 111, a plurality of other endless bodies suitable for being filled with the treatment liquid 7 and/or for mechanically stretching the fabric rope 5 during traction by the motorized roller 9. These circulation bodies may be arranged at the bottom of the U-shaped part 111, either above or below it.

Another advantage is that the U-shaped portion 111 of the tubular body 11 ensures that the treatment liquid 7 is always maintained in a certain quantity during use.

Another advantage is that the first tubular body 11 has a total elongation along a length, from the first end 110 to the second end 112, of substantially between 0.5 meters and 5 meters, and most preferably between 1 meter and 3.5 meters.

Another advantage is that the U-shaped section 111 of the first tubular body 11 has a length substantially between 0.25 and 1.5 meters, and most preferably between 0.35 and 1.2 meters, wherein the length comprises two descending and ascending sections of the U-shaped section 111 and a horizontal connecting section between them.

A further advantage is that the length of the descending and ascending portions of the U-shaped portion 111 of the first tubular body 11 is substantially between 0.1 and 0.7 meters, and most preferably between 0.20 and 0.55 meters.

Fig. 2 shows three different variants of the U-shaped portion of the first tubular body 11, indicated with the reference numbers 111, 111' and 111 ", respectively. This variation is due to the difference in the height of the U-shaped portion and the overall length of the tubular body.

As shown in the drawing, the U-shaped portion 111 may be provided directly at a lower portion of the nozzle 13.

As shown in the drawings, the descending and/or ascending segments of the U-shaped portion 111 of the first tubular body 11 extend in a vertical or substantially vertical direction.

A length of between 0.1 and O.7 meters, preferably between 0.20 and 0.55 meters, which is at least the descending part of the U-shaped section 111, possibly also in combination with a part of its vertical or substantially vertical direction, such that the combination of rope fabric 5 and treatment liquid 6 achieves a speed at which re-lifting along the ascending part is possible without reducing the fabric speed. Advantageously, the nozzle 13 comprises one or more dispensing nozzles provided for dispensing the treatment liquid 7.

Advantageously, a plurality of dispensing nozzles can be provided, which can be arranged around the nozzle at the opening of the first tubular body 11, so as to spray 360 degrees onto the fabric rope.

Advantageously, the dispensing nozzle is adapted to dispense the treatment liquid 7 through a jet of liquid under pressure and/or speed so as to exert a thrust on the fabric in rope form 5 in the direction of the drawing exerted by the motorized roller 9.

The advantage is that the motorized roller 9 is housed in a box-shaped body 90, which body 90 connects the first tubular body 11 and the second tubular body 12.

Advantageously, the first tubular body 11 is substantially completely housed inside the treatment drum 3.

It is advantageous that the treatment liquid 7 may be a staining liquid comprising a dye and auxiliary chemicals.

The treatment liquid 7 may be a washing liquid, a bleaching liquid or a disinfecting liquid for the textiles 5.

The invention also relates to a method for treating a fabric, in particular for dip dyeing a fabric in rope form, comprising the following steps: the fabric rope 5 is pulled through the first tubular body 11, which first tubular body 11 comprises a U-shaped portion 111 at least partly containing the treatment liquid 7, in order to treat said fabric rope 5 with such treatment liquid 7.

The method has the advantages that the method also comprises the following steps: the fabric rope 5 is mechanically deformed in the passage through the U-shaped portion 111 of the first tubular body 11.

It is an advantage that the method for treating a fabric comprises the steps of: mechanically stretching the fabric in rope form 5 in the passage along a first section of the U-shaped portion 111 of the first tubular body 11, and performing the step of mechanical stretching. The fabric in rope form 5 is compacted in the channel along the second section of the U-shaped portion 111 of the first tubular body 11.

The first section has the advantage of a descending section of the U-shaped portion 111 of the first tubular body 11, while the second section has the advantage of an ascending section of the U-shaped portion 111 of the first tubular body 11.

In particular, the method comprises a step of mechanically stretching the fabric rope 5 in a passage from the first end 110 of the tubular body 11 to the bottom of the U-shaped portion 111.

And a step of mechanically compacting the fabric rope 5 in the passage from the bottom of the U-shaped portion 111 of the first tubular body to the bottom 112 of the second section of the tubular body 11, as shown in fig. 5.

In this way, the fabric rope 5 is stretched in the section from the nozzle 13 to the U-shaped portion 111 and compacted in the section from the U-shaped portion 111 to the cross-lapper device 15.

This alternating stretching and compacting of the fabric rope 5 along the passage of the first tubular body 11 tends to form folds, creases and wrinkles which affect the process. The invented dying machine avoids this drawback of the existing machines.

In practice we have noticed how the machine for treating fabrics, in particular for exhaust dyeing of fabrics in rope form, according to the present invention, performs the task and the intended aim, so as to treat the fabrics in an optimal way.

Another advantage of the machine according to the invention consists in the fact that: the fabric is treated uniformly over its entire length.

Another advantage of the present invention as a fabric dying machine is the prevention of the formation of wrinkles, creases and wrinkles. In fact, the current machines press the folded fabric inside the basket, which, due to its own weight, is immersed in the treatment liquid, causing the fabric to wrinkle and the treatment liquid to spread, resulting in an uneven dyeing liquid.

In the machine of the invention, the passage of the fabric through the U-shaped portion causes a mechanical deformation of the fabric, removing possible wrinkles previously formed on the fabric introduced into the basket.

Furthermore, given that the fabric is cyclically pulled along a closed treatment path, in each cycle the fabric undergoes a different stretch, preventing the fabric from creasing, folding and compacting along the one that occurred in the previous cycle.

Another advantage of the machine for treating fabrics according to the present invention is that it is more efficient in treating fabrics, since the fabrics receive the treatment liquid from the nozzles and absorb it while also soaking in the treatment liquid bath inside the U-shaped portion of the tubular body.

In fact, in the previous processes, the treatment liquid cannot stagnate in the delivery channel of the machine, since it continues to flow along the delivery channel without stopping.

Moreover, another advantage of the machine for treating fabrics according to the present invention lies in the fact that: within the U-shaped portion of the tubular body, the fabric is accurately immersed in the treatment liquid while also being subjected to mechanical deformation. In fact, the fabric deforms as a result of stretching or compression, helping to promote the action of the treatment liquid in the fabric to be treated and to allow the penetration of the treatment liquid inside the material from which the fabric is made.

The above technical advantages of the machine according to the invention, in particular as regards the aspects relating to stretching and mechanical compression that take place in the tubular body, are also determined by the actual overall length of the tubular body, which is an innovation compared to other related machines.

The machine for treating fabrics, as envisaged by the present invention, is easy to repair and retrofit, all falling within the scope of the inventive concept. Moreover, all the details may be replaced with technically equivalent elements. In practice, the materials used, as well as the dimensions, may be adjusted as required according to the technical requirements.

In practice, any materials may be used as desired, so long as they are suitable for the particular use, size, and shape.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and not restrictive, and various changes and modifications may be made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention, which is defined by the claims.
