Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for coloring textile products, such as coloring and forming patterns such as stripes on textile products such as slivers.

[Conventional technology]

Formation of striped patterns on textiles such as slivers has been conventionally carried out by Vigoro printing, and textiles on which striped patterns have been formed are used to form marbled fabrics and the like. Such Vigoro printing is generally carried out using an apparatus as shown in FIG. That is, this Vigoro textile printing apparatus 30 is provided with a printing paste box 32 on a mounting base 31, and a liquid supply roll 33 is disposed within the printing paste box 32, and at the same time, a felt roll is brought into pressure contact with this liquid supply roll 33. 34 is provided, and furthermore, an engraving roll 35 is provided opposite to this felt roll 34. And the mounting base 31
A gill 36 in which a large number of needles are planted in a distributed manner is provided, and the sliver 38 is pulled out from inside a plurality of cans 37 and arranged in parallel with a rotating roll 39. The sliver 38 is passed through the gill 36 to form a sheet-like web 40, and then The printing paste supplied from the printing paste box 32 is passed between the felt roll 34 and the engraving roll 35 for printing, is wound up by the first and second winding rolls 41 and 42, and is further oscillated from side to side. A shaking plate 43 is used to shake off the product onto a product table 44. The felt roll 34 and the engraving roll 35
As shown in FIG.
5 is impregnated with printing paste, and a sheet-like web 40 is passed between this and an engraving roll 35 having a spiral ridge 45 on its outer peripheral surface. This is done by printing the diagonal striped pattern 46 by pressing.

This type of Bigolo printing apparatus 30 has a long history and has been used for producing marbled worsted yarn, but since it is difficult to print thick textiles, the sliver 38 is
Once passed through the gill 36 to form a sheet and then subjected to printing (
Therefore, even if you try to increase the printing efficiency by increasing the feeding speed of the sliver 38, the speed at which the sliver 38 passes through the gill 36 is naturally restricted (mechanically, the gill is not suitable for high-speed operation, and in high-speed operation where it can be operated, the fiber The problem is that printing efficiency cannot be increased beyond a certain limit. In addition, since the above-mentioned Vigoro textile printing apparatus 30 is limited to textiles in a dry state, it cannot be continuous with the coloring process in which textiles are ground-dyed in advance, and it is not possible to create a continuous line for ground-dying and printing. This is a hindering factor. That is, the above-mentioned device is equipped with a gill 36, and since this gill 36 cannot pass the ground dyeing sliver containing moisture, it is impossible to integrate the above-mentioned device 30 with the sliver ground-dying process. It is.

[Problem that the invention seeks to solve]

As mentioned above, conventional Vigolo printing equipment has problems in terms of coloring efficiency, and also problems in continuous dyeing and printing of textile products such as sliver. In particular, in the field of bigolo textile printing, technological innovation is lagging behind other dyeing processing fields, and a solution to the above problems is strongly desired.

For this reason, the present inventors installed a hollow drum for colored liquid outflow having an outflow hole on the outer circumferential surface and a hollow drum for colored liquid suction having suction holes on the outer circumferential surface vertically opposite each other, and created a space between the two drums. A textile product such as a sliver is sandwiched between the two hollow drums and passed by the rotation of both hollow drums, and when the textile product such as a sliver passes through, the coloring liquid is discharged from the outflow hole on the outer peripheral surface of the hollow drum for coloring liquid to flow out. At the same time as the liquid flows out, this colored liquid is sucked through the suction holes on the outer circumferential surface of the hollow drum for colored liquid suction, and the colored liquid is passed through the textiles to create striped patterns etc. on the textiles such as slivers. Developed technology to form patterns and filed a series of patent applications (Japanese Patent Applications 170-170-170256-1702)
No. 59 and Japanese Patent Application No. 174373/1982). These new technologies can solve all of the problems of the conventional Togoro printing equipment as described above, but in actual use, dark striped patterns on textiles such as slivers are produced. When forming a dye, there is a problem in that even if the concentration of a coloring liquid such as a dye is set to a fairly high concentration, it is difficult to obtain a deep color.

This invention was made in view of the above circumstances, and it is possible to efficiently color textile products such as sliver with striped patterns, etc., as well as realize continuous dyeing process for textile products, and furthermore, it is possible to color textile products such as slivers in striped patterns. The purpose is to provide a method for coloring textiles that can be colored.

[Means for solving problems]

In order to achieve the above object, the method for coloring textiles of the present invention involves sandwiching the textile between a hollow drum for discharging a coloring liquid and a hollow drum for suctioning a coloring liquid, which are arranged vertically opposite to each other. The colored liquid is caused to pass by rotating both hollow drums, and when the textile passes through, the colored liquid is caused to flow out from the outflow part on the outer peripheral surface of the hollow drum for flowing out the colored liquid, and at the same time, this outflowing colored liquid is sucked into the colored liquid suction. A method for coloring textile products, in which the coloring liquid is suctioned into the drum by a suction part on the outer peripheral surface of a hollow drum for use, and the coloring liquid is passed through the textile product to color the textile product at appropriate intervals,
A configuration is adopted in which the amount of colored liquid flowing out of the hollow drum for colored liquid flowing out is set to an amount greater than the amount absorbed by the textile product.

In other words, the present inventors have conducted a series of studies on the reason why deep color dyeing cannot be achieved even when the dye concentration is much higher than usual when coloring textile products using the above new technology. During actual operation using equipment related to the technology, in order to use the colored liquid flowing out from the hollow drum for colored liquid flowing out without wasting it, most of the colored liquid flowing out is absorbed into the textile product, and the hollow drum for colored liquid suction They discovered that the problem lies in preventing the metal from reaching the inside of the drum and being disposed of. Based on this, by setting the amount of colored liquid flowing out from the hollow drum for colored liquid flowing out to an amount greater than the amount absorbed by the textile, it is possible to achieve deep coloring that is approximately proportional to the concentration of coloring agents such as dyes. This invention was achieved by discovering that

Next, the present invention will be explained in detail based on examples.

〔Example〕

FIG. 1 shows an embodiment of the apparatus for coloring textiles used in the present invention, and FIG. 2 shows a longitudinal section thereof. In these figures, reference numeral 1 denotes a pair of left and right metal frames, and in this frame 1, a hollow drum 2 for discharging a colored liquid and a hollow drum 3 for sucking a colored liquid made of stainless steel are provided with a gap 3a for passing the textile product. They are arranged vertically opposite each other. The hollow drum 2 for discharging the colored liquid is rotatably attached to a main shaft 5 fixed to a shaft holder 4 of the frame 1 via a bearing 6, so as to rotate in the circumferential direction.

This hollow drum 2 has colored liquid outflow holes 7 on its outer peripheral surface.
A plurality of outflow grooves 8 having a groove bottom thereof are formed at predetermined intervals in the circumferential direction, and each of the outflow grooves 8 has a plurality of long slit plates made of stainless steel as shown in FIG. 9 are arranged side by side, and short stainless steel partition plates 10 are set upright thereon at predetermined intervals. A slit plate block 11 has the slit plate 9 side facing the groove bottom, and the longitudinal direction of the slit plate 9 facing the outflow groove. It is inserted and fixed in a state that matches the length direction of 8. The slit plate 9 and the partition plate 10 have surface oils and fats removed by alkali treatment, and subsequent acid treatment to form irregularities on the surface to increase their affinity for water. Further, as shown in FIG. 2, the colored liquid suction hollow drum 3 is rotatably attached to a main shaft 5a fixed to the frame 1 via a bearing 6, and rotates in the circumferential direction. There is. The outer circumferential surface of the hollow drum 3 has a plurality of colored liquid suction grooves 1 which are connected to the communication holes 12 on the lower side.
3 (see FIG. 4) are formed at predetermined intervals in the circumferential direction. The colored liquid suction groove 13 and the communication hole 12 are communicated with each other by a colored liquid suction hole 14, and one end of the communication hole 12 is formed as a suction opening 15 on the mirror-finished surface of one side of the colored liquid suction hollow drum 3. It's open. 16 is a vacuum pump (
A suction cylinder made of polyfluoroethylene is connected to a suction cylinder (not shown), and its cylinder mouth is fixed with a fixing fitting 16a so as to be in sliding contact with a portion near the top of one side of the hollow drum 3, and the textiles can pass through. The suction opening 15 of the communication hole 12 of the hollow drum 3 for suctioning the colored liquid, which has reached the empty space 3a, is aligned with the cylindrical opening of the drum itself, and the suction force of the vacuum pump is applied to the suction groove communicating with the communication hole 12. It is designed to affect up to 13. This suction groove 13 is filled and fixed with a polyvinyl formal sponge for preventing dust from entering. Further, the colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3 each have gears 17 and 17a on the other side that mesh with each other. The gear 17a is connected to the rotating shaft 1 of the motor 18.
By meshing with a gear 20 provided at 9, it is rotationally driven by a motor 18. This results in
The colored liquid outflow hollow drum 2 and the suction hollow drum 3 rotate synchronously so that the plurality of outflow grooves 8 and suction grooves 13 are successively aligned with each other across the textile article passing gap 3a. The main shaft 5 of the colored liquid outflow hollow drum 2 is a hollow shaft,
Nozzles 21 are formed in the upper part of the hollow shaft 5 at appropriate intervals in the axial direction, so that the colored liquid supplied from the nozzles 21 to the internal space of the hollow main shaft 5 is evenly distributed and falls. On the other hand, the main shaft 5 of the colored liquid suction hollow drum 3
A is a bare axis.

The hollow main shaft 5 is connected to the hollow main shaft 5 via a pipe (not shown).
A constant flow liquid pump (
(not shown), and as mentioned above, the hollow drum 3 for suctioning the colored liquid is supplied with the suction groove 13 of the colored liquid by its own rotation as described above. Every time it is located in the gap 3a, it is vacuumed by a vacuum pump through the communication hole 1-2. As a result, the colored liquid fed into the hollow main shaft 5 of the hollow drum 2 for outflowing the colored liquid flows down from the nozzle 21 of the main shaft 5 into the hollow drum 2 for outflowing the colored liquid, and then at the bottom of the outflow groove 8. The colored liquid reaches the outflow groove 8 from the outflow hole 7 and is held uniformly in the longitudinal direction of the outflow groove 8 by capillary action between the slit plates 9 of the slit plate block 11 (see Fig. 3). When the groove 8 and the suction groove 13 match in the textile article passing gap 3a, the suction force of the vacuum pump causes the outflow groove 8, the suction groove 13. Suction hole 14. It is discharged to the outside from the suction cylinder 16 via the communication hole 12. This discharged liquid is replenished with colorant as appropriate and is again supplied to the hollow main shaft 5 of the hollow drum 2 for discharging the colored liquid.

In addition, 23 is a body with a handle, which raises and lowers the shaft holder 4 and adjusts the amount of the gap 3a between the hollow drum 2 for colored liquid outflow and the hollow drum 3 for colored liquid suction.

In this configuration, the motor 18 is rotated to drive the gears 17 and 17a to rotate in the direction of the arrow, and the gap 3 between the colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3 is
Coloring is performed by passing several to several dozen wool slivers 24 through a in parallel (see FIG. 5). In this case, each sliver 24 maintains a large set-like shape until it enters the gap 3a, but when it passes through the gap 3a, the pressure applied causes the sliver 24 to be integrated as a whole, and at the same time is formed into a substantially flat sheet shape. and as shown in FIG. 6, the outflow groove 8 of the colored liquid outflow hollow drum 2 and the suction groove 13 of the suction hollow drum 3
A striped pattern is formed by suctioning and passing the colored liquid in the direction of arrow A when the two match. In this case, the intervals between each visit of the striped pattern are as follows:
This approximately matches the circumferential spacing of 3. In this way,
A plurality of slivers 24 are simultaneously colored and formed into a sheet shape. In particular, in the case of coloring in this manner, the amount of colored liquid flowing out from the hollow drum 2 for colored liquid flowing out is set to be larger than the amount absorbed by the wool sliver 24. For example, the amount of colored liquid flowing out is about 1.2 to 5.0 times the amount of suction above, preferably 1.5 times.
Good results can be obtained by setting the ratio to about 2.5 times. As a result, a sufficient amount of the colored liquid passes through the sliver 24 and reaches the colored liquid suction hollow drum 3, so that when the coloring concentration of the colored liquid is increased, it is almost proportional to the coloring concentration. It becomes possible to achieve deep coloring.

In this way, the coloring liquid supply flow rate is set to 80cc/min.
(4 slivers x 8 m/win) with dye concentrations of 64 gel and 12 B gel, and with a coloring liquid supply flow rate of 120 cc/sin and dye concentrations of 64 g/l and 128 g/il. The degree of coloring of the sliver 24 when
The coloring liquid supply flow rate was set to 40 cc/win, which is approximately the maximum amount that the wool sliver 24 can absorb, and the dye concentration was 64 g.
When set to el and when set to 128g/l)
Table 1 shows a comparison between the results and the results of a conventional example (conventional Bigolo printing, dye density 64 gel).

Dye used: Ac1dol Black-P, BAS
In the comparative example manufactured by Company F, in which the supply flow rate was set to 40 cc/min, the dye concentration was 64 g/I! Even if it were doubled from 128 g/Il, it was not possible to achieve a deep coloring equivalent to conventional Vigoro printing, and the four slivers shown in Figure 7 (feeded in a direction perpendicular to the paper surface) could not be achieved. The colored liquid permeates inside the sliver 24 in an inverted triangular shape from the colored liquid outflow hollow drum 2 side to the colored liquid suction hollow drum 3 side, and the white background portion 24a which is the uncolored part of the sliver 24 A large amount remains on the colored liquid suction hollow drum 3 side.

24b is a colored portion. This is because, in the comparative example, the amount of colored liquid supplied to the hollow drum 2 for flowing out the colored liquid is limited so that the colored liquid does not stay in the sliver 24 and reach the hollow drum 3 for sucking the colored liquid. be.

Therefore, as shown in the table above, in the comparative example, even if the dye concentration is increased to give a deep color, the ratio of the white background portion (undyed portion) 24a in the sliver 24 is high, so that the overall is in a state where the dark coloring is not done. On the other hand, in the embodiment, since the amount of coloring liquid supplied to the hollow drum 2 for coloring liquid outflow is increased to an amount greater than the amount absorbed by the sliver 24, the undyed portion in the sliver 24 is extremely large. The color decreases, and the entire sliver 24 becomes colored.

As a result, as shown in the table above, it becomes possible to achieve deep coloring depending on the dye concentration.

As described above, according to this embodiment, it becomes possible to realize deep coloring that almost corresponds to the dye concentration, and the degree of freedom in coloring concentration is significantly improved. In addition, since there is no need to use a gill, even thick textiles can be colored as they are, and there is no restriction on the feed speed of textiles due to passing through a gill, so it is possible to significantly improve coloring efficiency. Become.

In addition, striped patterns can be formed even on textiles that have been ground-dyed and are still wet, making it possible to achieve continuous ground-dying pattern coloring.

FIG. 8 shows another device for use in the present invention. In this device, a hydrophilic polyvinyl formal sponge 25 having continuous pores is inserted and fixed into an outflow groove 8 of a hollow drum 2 for outflowing a colored liquid.

The rest is the same as the embodiment shown in FIG. This polyvinyl formal sponge 25 has the ability to retain the colored liquid, and has appropriate hydrophilicity to the extent that the color can be easily washed away with water when changing the type of colored liquid. From this point of view, the porosity is 70 to 95
%, preferably 86-92%, and the degree of formalization is 7.
It is most preferred to use 0-90% polyvinyl formal sponge 25, preferably 80-86%.

This device has the same effects as the above device, and also
Since the polyvinyl formal sponge 25 is inserted and fixed in the outflow groove 8 of the hollow drum 2 for outflowing the colored liquid, the colored liquid flowing out from the main shaft 5 of the hollow drum 2 becomes a polyvinyl formal sponge having continuous pores. 25, and when this uniformly held colored liquid matches the outflow groove 8 and the suction groove 13 of the suction hollow drum 3,
The colored liquid is caused to pass through the sliver by the negative pressure of the hollow drum 3 for suction, and as a result, it is possible to realize uniform coloring without uneven coloring. In addition, in the above-mentioned device, the colored liquid is not vacuum-suctioned by making the entire suction drum 3 hollow and vacuum suctioning the entire drum 3.
Since this is performed by vacuum suction, there is an effect that good suction can be performed without increasing the degree of vacuum.

FIG. 9 shows yet another device used in the present invention. In this device, a hollow drum 2 for discharging a colored liquid is composed of a hollow drum main body 2a and a sleeve 22 for discharging a colored liquid rotatably fitted around the outer periphery of the hollow drum body 2a, and a hollow drum 3 for suctioning a colored liquid is constituted by a hollow drum Consists of a main body 3b and a colored liquid suction sleeve 22° rotatably fitted around the outer periphery of the main body 3b,
The hollow drum bodies 2a and 3b are connected to holes 26 and 26, respectively.
The mounting is fixed on hollow fixed shafts 27 and 28 with a.

29, 29a are the two hollow drum bodies 2a.

A pair of outflow grooves are formed facing each other in 3b. Both sleeves 22, 22' are adapted to rotate synchronously by gears 4B, 48a, and grooves 47, 47a are formed on the outer peripheral surface at appropriate intervals in the circumferential direction. When the grooves 47, 47a of both sleeves 22, 22' face each other across the textile passing gap 3a, the colored liquid flows from the hole 26 of the hollow fixed shaft 27 to the groove 29 of the hollow drum body 2a.
The flow follows the path of the outflow groove 47 of the colored liquid outflow sleeve 22 → the suction groove 47a of the colored liquid suction sleeve 22'' → the suction groove 29a of the colored liquid suction hollow drum body 3b → the hole 26a of the hollow fixed shaft 28 It is used to color textiles.

Moreover, FIG. 10 shows a device that combines the structure of the hollow drum 2 for discharging the colored liquid shown in FIG. 2 and the structure of the hollow drum 3 for sucking the colored liquid shown in FIG. 9, and FIG. 9 shows a device that combines the structure of the hollow drum 2 for discharging colored liquid shown in FIG. 9 with the structure of the hollow drum 3 for sucking colored liquid shown in FIG.

The above device, like the device shown in Figure 1, requires the following:
By setting the colored liquid supply amount of the colored liquid outflow hollow drum 2 to be greater than the colored liquid suction amount of the colored liquid suction hollow drum 3, the same effect as in the embodiment using the apparatus shown in FIG. 1 can be achieved. It is uruno.

In the above device, the hollow drum 29 for colored liquid outflow and the hollow drum 3 for suction of colored liquid have an outflow groove 8 with an outflow hole 7 and a suction groove 1 with a suction hole 14 as an outflow part and a suction part.
However, the outflow part and the suction part are not limited to such elongated shapes, and may be configured by continuously forming round holes as shown in Fig. 12. There isn't.

Further, the outflow portion and suction portion may not be formed linearly, but may be formed inclined in the axial direction, as shown in FIG. 13. In addition, in the above embodiment, wool sliver is the object to be colored, but the object to be colored is not limited to this, and natural fibers such as silk, cotton, linen, etc., polyester, nylon, acrylic, rayon, etc. It can be applied to a wide range of single or mixed fibers, and its shapes include not only slivers but also tops, wraps,
It may be in any shape such as a web.

〔Effect of the invention〕

As described above, the present invention uses the above-mentioned special textile coloring device and sets the amount of coloring liquid flowing out from the hollow drum for coloring liquid outflow to an amount greater than the amount absorbed by the textile. In order to color textile products, it becomes possible to achieve deep coloring that is proportional to the coloring agent concentration, and the degree of freedom in coloring can be greatly improved. Furthermore, this invention does not require a gill like the conventional Vigoro dyeing machine, so thick textiles can be colored as is.
Further, a significant improvement in coloring efficiency can be realized. Furthermore, it is possible to form striped patterns etc. even on textiles that have been ground-dyed and remain wet, and it is also possible to achieve continuous ground-dying pattern coloring.
