Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a textile coloring device for coloring and forming patterns such as striped patterns on textile products such as slivers.

(Prior art) Conventionally, printing striped patterns etc. on textile products such as slivers in order to obtain threads used for manufacturing marbled textiles etc. has been carried out by Vigoro printing, which has a long history. It's been coming. The equipment used for this Bigolo printing is as shown in Figure 8.
A printing paste box 15 is provided on the mounting base 14, a liquid supply roll 16 is disposed within the printing paste box 15, a felt roll 17 is provided in pressure contact with the liquid supply roll 16, and the felt roll It has a structure in which an engraving roll 18 is placed opposite to 17.

The mounting base 14 is provided with a gill 19 in which a large number of needles are distributed and implanted, and the sliver 22 drawn out from the inside of a plurality of cans 20 and aligned in parallel by a rotating roll 21 is provided on the mounting base 14. , the sheet-like web 23 is made into a sheet-like web 23 by passing through the gill 19, and then the printing paste supplied from the printing paste box 15 is printed by passing this sheet-like web 23 between the felt roll 17 and the engraving roll 18. the first and second winding rolls 2
4 and 25, and then shaken down onto a product table 27 by a shaking plate 26 that swings from side to side.

As mentioned above, printing by the conventional Vigolo printing apparatus is based on printing using the felt roll 17 and the engraving roll 18. That is, as shown in FIG. 9, a felt roll 17 is impregnated with printing paste, and the felt roll 17 and an engraved roll 18 opposite to the felt roll 17 and having a spiral protrusion 28 on the outer peripheral surface are formed.
A sheet-like web 23 is passed between the sheet-like web 23 and the spiral protrusions 28 are pressed against the sheet-like web 23, thereby printing a diagonal striped pattern 29. Therefore, by providing a plurality of sets of the felt roll 17 and the engraving roll 18 to perform multicolor printing, the printed sheet-like web 23 absorbs water and winds around the rolls of the next and subsequent sets. However, this was not practical due to problems such as difficulty in controlling the gill and multiple roll combination systems. In addition, since it is difficult to print thick textiles with the Bigolo printing apparatus, the sliver 22
It is necessary to pass it through a gill 19 in order to make it into a sheet-like web 23, and since the mechanism of the gill is not suitable for high-speed operation, the speed at which it passes through the gill 19 is naturally restricted, and there is a limit to the improvement of printing efficiency. Ta. Furthermore, since it is not possible to pass the ground dyeing sliver containing moisture through the gill 19, it has been impossible to connect the process of ground dyeing textiles with the bigolo printing process. Moreover, since the Vigoro printing apparatus uses a felt roll 17 for printing, continuous use for a long time causes compression hardening of the felt, which reduces the amount of printing paste absorbed and causes the color of the print to become lighter. There were also some problems.

In order to solve the above-mentioned problems, the present applicant has proposed a method for coloring textiles or an apparatus therefor in which a coloring liquid is discharged by an air flow, as disclosed in Japanese Patent Application No. 170-256-1983.
The proposal was made through a total of 11 applications, including Japanese Patent Application No. 1982-170257 and Japanese Patent Application No. 170258-1981. The technology described in this application is extremely effective in solving the above problems.

Regarding the technical means that form the core of the said application, Section 4
To explain briefly with the drawing, U is a drum unit in which a hollow drum 2' for discharging a colored liquid and a hollow drum 3' for suctioning a colored liquid are vertically opposed to each other on a pair of left and right frames 1. Drum 2′,
3', a plurality of colored liquid outflow holes 7' and colored liquid suction holes 8', which are slits formed along the axial direction, are bored at predetermined intervals in the circumferential direction. 3', the colored liquid is intermittently flowed out from the colored liquid outlet hole 7', and at the same time, the flowing colored liquid is transferred to the colored liquid drawing hole 8'.
The textile product is colored at appropriate intervals by suctioning the textile product.

In this device, the coloring liquid is forced to pass through the inside of the textile by outflow and suction, so it is possible to sufficiently color even thickly drawn textiles, making it possible to color even thick textiles. There is no longer a need to use gil as with printing equipment. As a result, it is possible to aim at improving coloring efficiency without being restricted by speed restrictions caused by the gill process. Furthermore, since the fiber bundles that are ground-dyed and remain wet are not formed into thin wraps, there is no problem of winding them around the next set of rolls, and these textiles can be colored. For this reason, it becomes possible to realize the continuous process of ground dyeing and pattern dyeing. Furthermore, by omitting the gill process, the textile product will not be damaged by cutting or the like.

As mentioned above, the textile coloring device proposed by the present applicant was a great leap forward from the conventional Vigoro printing device in all aspects, but the present inventors have made several improvements in order to make it even better. I have tried various improvements. The present invention is one of such improved inventions, and was discovered as a result of studies aimed at forming more beautiful and uniform color patterns such as striped patterns.

That is, in the textile coloring apparatus shown in FIG. 4, two hollow drums 2' and 3' of the same shape and size, each having holes 7' and 8', which are slits of the same length, are used for the coloring liquid to flow out. Hollow drums 2' and 3' for sucking colored liquid are installed vertically opposite each other. As a result, the range of textile products may expand. In this case, as shown in FIG.
When the coloring liquid suction hole 8' does not extend across both ends of the width of the textile product 12, the coloring mode changes to, for example, the sixth
The result will be as shown in the figure. That is, at both ends of the textile article 12, there is no passage A of the colored liquid (as shown in FIG. 5), and as a result, there are uncolored portions 30 at both ends of the textile article.
(Illustrated in FIG. 6) will be colored while remaining.

Furthermore, if the passing textiles are simply sandwiched from above and below between the colored liquid outflow hollow drum 2' and the colored liquid suction hollow drum 3', the textiles tend to be poorly contained, which can lead to uneven coloring. There is also the problem of being connected to

(Problems to be Solved by the Invention) The present invention brilliantly solves the problems of the conventional Vigoro textile printing apparatus, and makes it possible to highly efficiently color patterns such as striped patterns on textile products such as slivers.
This is a completely new textile coloring device that can be connected continuously with the background dyeing process. In other words, it solves the problem of undyed areas in coloring devices that use air flow, and creates more beautiful and uniform continuous patterns such as striped patterns. The purpose is to provide a device that can

(Means for Solving the Problems) In order to achieve the above object, the textile coloring device of the present invention has the following configuration. That is, in a pair of left and right frames, a hollow drum for colored liquid outflow and a hollow drum for colored liquid suction are disposed vertically facing each other across a gap for passage of textiles, and the hollow drum for colored liquid outflow is colored. A plurality of colored liquid outflow holes, which are slits formed along the axial direction, are fitted into the recesses provided in the working surface of the hollow drum for liquid suction, and a plurality of colored liquid outflow holes, which are slits formed along the axial direction, are formed in the working surface of the hollow drum for colored liquid outflow in the circumferential direction. At the same time, a plurality of colored liquid suction holes, which are slits formed along the axial direction, are bored at predetermined intervals in the circumferential direction on the working surface of the hollow drum for colored liquid suction. The gist thereof is that a tuning means is provided for boring the colored liquid suction holes over the coloring liquid and sequentially aligning the colored liquid suction holes with the colored liquid outlet holes.

Therefore, the textile coloring apparatus of the present invention does not perform printing using rollers like the conventional Vigolo printing apparatus, but rather the coloring liquid flows out from the hollow drum for coloring liquid outflow, and the coloring liquid flows out from the hollow drum for coloring liquid suction. By suctioning this outflowing colored liquid, the colored liquid completely passes through the interior of the textile, making it possible to sufficiently color even thick textiles. As a result, the gill process is omitted, making it extremely efficient without being subject to speed restrictions. Further, in the textile coloring device of the present invention, the working surface of the coloring liquid suction hollow drum is concave, and the coloring suction holes are provided across both ends of the concave portion, so that the textile product can be removed from the hollow drum for coloring liquid to flow out. As it passes in a stable state between the working surface of the drum and the concave portion of the working surface of the colored liquid suction hollow drum, uniform coloring is applied to both ends of the width.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

(Example) FIG. 1 is a front view showing an example of the textile coloring apparatus of the present invention, and FIG. 2 is a longitudinal sectional view thereof.

In FIGS. 1 and 2, reference numeral 1 denotes a pair of left and right metal frames, in which a stainless steel hollow drum 2 for discharging the colored liquid and a hollow drum 3 for suctioning the colored liquid are installed to allow the textiles to pass through. They are disposed on the main shaft 4 via a bearing 5 so as to face each other vertically with a gap in between. As shown in FIG. 1, FIG. 2, and FIG. 3 which is an enlarged view of the main part, a recess 6 is provided on the working surface of the colored liquid suction hollow drum 3. The hollow drum 2 for distributing the colored liquid is disposed in an inserted state.

On the working surface of the hollow drum 2 for colored liquid outflow,
A plurality of colored liquid outflow holes 7, which are slits formed along the axial direction, are bored at predetermined intervals in the circumferential direction, and the colored liquid suction hollow drum 3
A plurality of colored liquid suction holes 8, which are slits formed along the axial direction, are bored in the working surface at predetermined intervals in the circumferential direction, and across both width ends of the recess 6 provided in the working surface. has been done.

The colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3 each have gears 9 and 9a that mesh with each other, and the gear 9a provided on the colored liquid suction hollow drum 3 is connected to a motor. The coloring liquid outflow hole 7 meshes with a gear 10 provided on a rotating shaft 11 and is rotationally driven by a motor 11.
This is a means for aligning the coloring liquid suction hole 8 with the colored liquid suction hole 8.

In this configuration, the motor 11 is rotated to rotationally drive the gears 9, 9a, and a number of textile articles 12, for example wool slivers, are inserted into the gap between the colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3. Color a book or dozens of books in parallel. In this case, the sliver maintains its thick string-like shape until it enters the gap, but is formed into a substantially flat sheet by applying appropriate pressure when passing through the gap. At this time, the textile product 12 fits into the recess 6 of the colored liquid suction hollow drum 3 and passes between the two hollow drums 2 and 3 without shifting, and as shown in FIG. 3, the colored liquid flows out. A striped pattern is formed by suctioning and passing the colored liquid in the direction of arrow A when the holes 7 and the colored liquid suction holes 8 match. Therefore, the distance between the lines of the formed striped pattern almost matches the distance between the colored liquid outflow holes 7 and the colored liquid suction holes 8 in the circumferential direction.

As described above, according to this embodiment, when the textile article 12 such as a sliver passes through the textile article passing gap surrounded by the recess 6 of the colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3, In order to forcibly pass the colored liquid through the textile article 12 such as a sliver by the suction force from the colored liquid suction hole 8, and color it.
As shown in FIG. 7, even thick textiles can be colored with a uniform striped pattern 13 without leaving any uncolored portions on both ends of the width. Therefore,
It is no longer necessary to use a gill as in the past, and the feeding speed of textile products is not restricted by the use of a gill, making it possible to increase the coloring speed of textile products. Furthermore, since no gill is used, it is possible to ground-dye the textile and apply it to the apparatus while still wet to form a striped pattern, making it easy to integrate the process with the ground-dying process. Further, since both the hollow drums 2 and 3 are made of stainless steel, they do not undergo compression hardening unlike felt, and can be used for a long period of time without any problem.

Note that instead of driving both the hollow drums 2 and 3 with the motor 11 and feeding the textile product 12 with the driving force,
The textile product 12 may be pulled from the front in the feeding direction and fed by that force.

In addition, the textile coloring device of the present invention can select not only wool slivers but also various natural fibers and synthetic fibers singly or in combination, and in terms of shapes, not only slivers but also wool slivers. It can be used in any shape such as , top, wrap, web, etc.

(Effects of the Invention) As described above, the textile coloring apparatus of the present invention successfully solves the problems of the conventional Vigolo printing equipment, and the shape of the hollow drum allows the coloring liquid to pass through the textiles. This textile coloring device has an extremely excellent effect in that it can uniformly form striped patterns and the like at extremely high speed without leaving any undyed areas.
