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 stripes on textiles 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. This bigoro printing (l, .) is generally carried out using an apparatus as shown in FIG. That is, this Bigolo textile printing apparatus 3o 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, and furthermore, this felt roll 34
An engraving roll 35 is provided oppositely. Then, a gill 36 in which a large number of needles are distributed and implanted is provided on the mounting base 31, and the sliver 38 is pulled out from inside a plurality of cans 37, arranged in parallel with a rotating roll 39, and then hung on the gill 36 to form a sheet. web 40, then felt roll 3
4 and the engraving roll 35, the printing paste box 32
Printing is performed using the printing paste supplied from the first and second
The product is wound up by winding rolls 41 and 42, and further shaken down onto a product table 44 by a shake-off plate 43 that swings from side to side. In printing using the felt roll 34 and the engraving roll 35, as shown in FIG. This is carried out by passing the sheet-like web 40 between an engraving roll 35 having stripes 45 and printing a diagonal striped pattern 46 by pressing the spiral protrusions 45.

This type of Bigolo printing apparatus 30 has a long history and has been used for producing marbled worsted yarn, but since printing on thick textiles is difficult, the sliver 38 is first passed through the gill 36. It must be made into 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 regulated. This method has the disadvantage that the printing efficiency cannot be increased beyond a certain limit. In addition, in the Vigolo printing apparatus 30, the felt of the felt roll 34 is compressed and hardened with continued use, so the amount of printing paste absorbed decreases, and the color tone of the print becomes lighter after long-term use. It also has some drawbacks. Furthermore, the above device 30
Since the printing target 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 this is an impediment to creating a continuous line for ground-dying and printing. 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 apparatuses have problems in coloring efficiency and homogeneous printing, and also in continuous dyeing and printing of textile products such as slivers. In particular, in the field of bigot printing, technological innovation is lagging behind other dyeing processing fields, and a solution to the above problems is strongly desired.

This invention was made in view of the above circumstances, and it is possible to efficiently and uniformly color textile products such as sliver with striped patterns, and also to make the background dyeing process of textile products continuous. The purpose is to provide a practical textile coloring device.

[Means for solving problems]

In order to achieve the above object, the textile coloring device of the present invention includes a circumferentially rotatable hollow drum for discharging a coloring liquid and a fixed hollow drum for suctioning a coloring liquid. The colored liquid outflow hollow drums, which are disposed one above the other with a gap in between, have a plurality of grooves formed at predetermined intervals in the circumferential direction on the outer circumferential surface thereof, each groove having a colored liquid flow hole at the groove bottom. A plurality of slit plates are arranged in parallel in the groove with one side edge facing outward, and the colored liquid suction hollow drum has a colored liquid circulation hole in the opposite part to the colored liquid outflow hollow drum. A sleeve having a plurality of through holes perforated at predetermined intervals in the circumferential direction is rotatably fitted on the outer periphery of the sleeve, and the sleeve has a plurality of grooves of the hollow drum for discharging the colored liquid and the sleeve. A synchronizing means is provided for synchronizing the rotation of the hollow drum for discharging the colored liquid and the sleeve so that the plurality of through holes of the sleeve sequentially align with the circulation holes of the hollow drum for sucking the colored liquid at the same timing. Take.

In other words, the apparatus of the present invention does not simply perform printing by printing like the conventional Vigoro textile printing apparatus, but uses a hollow drum for discharging the colored liquid and a hollow drum for suctioning the colored liquid having a sleeve. A textile product such as a sliver is passed between the drums, the colored liquid flows out from the hollow drum for outflow, and the colored liquid is sucked by the hollow drum for suction, and the colored liquid is forcibly drawn inside the textile product such as the sliver. Since the coloring process is carried out by passing through the dye, it is possible to directly color even thick textiles. Therefore, unlike in the past, there is no need to use a gill, and the phenomenon of restricting the feed rate of the textile article due to passing through the gill does not occur, so that a significant improvement in coloring efficiency can be realized. Furthermore, since no gill is used, striped patterns can be formed even on textiles that have been ground-dyed and remain wet, and continuous ground-dying and pattern coloring can be achieved. Furthermore, since felt rolls are not used as in the conventional method, uniform coloring can be achieved over a long period of time.

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 the second panel shows a longitudinal section thereof. In these figures, reference numeral 1 denotes a pair of left and right metal frames, on which a hollow drum 2 for discharging a colored liquid and a hollow tram 3 for suctioning a colored liquid made of stainless steel are vertically disposed opposite to 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 a plurality of grooves 8 formed at predetermined intervals in the circumferential direction on its outer circumferential surface, each having a colored liquid flow hole 7 at the groove bottom. A slit plate block 11 as shown in FIG. The slit plate 9 is inserted and fixed in such a manner that the longitudinal direction of the slit plate 9 is aligned with the longitudinal direction of the groove 8. Among the plurality of slit plates 9, the slit plates 9b and 9d other than the left and right sides 9a and 9e and the central slit plate 9c have spacer protrusions 12 formed on their front and back surfaces, as shown in FIG. As shown in FIG. 5 (an enlarged view of the circled part A in FIG. 3), the gaps 13 between the slit plates 9a, 9b, 9c, 9d, and 9a are held by the convex portions 12. There is. 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. On the other hand, the colored liquid suction hollow drum 3 is non-rotatably fixed to a main shaft 5a fixed to the frame 1, and the colored liquid suction drum 3 is attached to the outer periphery of the main shaft 5a via a bearing 6a. A suction sleeve 14 is fitted onto the outside so as to be rotatable in the circumferential direction. This hollow drum 3 for suctioning colored liquid
A slit-shaped flow hole 7a extending in the axial direction is formed in the portion facing the hollow drum 2 for discharging the colored liquid, and a slit-shaped communication hole 7a extending in the axial direction is provided on the outer circumferential surface of the colored liquid suction sleeve 14. A plurality of slit-shaped through holes 15 are bored at the same intervals as the grooves 8 in the colored liquid outflow hollow drum 2 in the circumferential direction. The main shaft 5 of the hollow drum 2 for discharging the colored liquid has a hollow interior, and the colored liquid mainly composed of dyes and pigments is fed thereto via a constant flow pump (not shown). ) and a hollow drum 3 for suctioning the colored liquid.
The main shaft 5a of the pipe 5 is also hollow inside.
It is connected to a vacuum pump (not shown) through c.

Both main shafts 5.5a are provided with holes 16, 163 at appropriate intervals, as shown in FIG. The liquid is allowed to flow down into the hollow drum 2 for outflow, and then allowed to reach the inside of the groove 8 through the colored liquid flow hole 7 at the bottom of the groove 8, and is held between the slit plates 9 of the slit plate block 11 by capillary action. When the groove 8 and the slit-shaped through hole 15 match the communication hole 7a, the retained liquid is drawn into the groove 8 by the suction force of the vacuum pump. Slit-shaped through hole 15. It is fed into the colored liquid suction hollow drum 3 via the circulation hole 7a, then fed into the main shaft 5a via the hole 16a, and discharged from there to the outside. This discharged liquid is replenished with colorant as appropriate and is again supplied to the hollow drum 2 for colored liquid discharge. The colored liquid outflow hollow tram 2 and the colored liquid suction sleeve 14 each have gears 17 that mesh with each other.
．． 17a, and a gear 17a provided on the colored liquid suction sleeve 14 meshes with a gear 20 provided on a rotating shaft 19 of a motor 18, so that it is rotationally driven by the motor 18. As a result, the colored liquid outflow hollow drum 2 and the sleeve 14 rotate synchronously so that the plurality of grooves 8 and the plurality of through holes 15 sequentially align with the flow holes 7a of the hollow drum 3 at the same timing.

The reference numeral 21 is a screw with a handle for raising and lowering the shaft holder 4 to adjust the gap between the colored liquid outflow hollow drum 2 and the colored liquid suction sleeve 14.

In this configuration, the motor 18 is rotated to drive the gears 17 and 17a to rotate in the direction of the arrow, and several wool slivers 22 are inserted into the gap between the colored liquid outflow hollow drum 2 and the colored liquid suction sleeve 14. Coloring is carried out with one to several dozen pieces in parallel (Figure 6). In this case, each sliver 22 maintains its large string-like shape until it enters the void, but is formed into a substantially flat sheet shape by the pressure applied when passing through the void, as shown in FIG. As shown in FIG.
The slit-shaped flow hole 7a of the hollow drum 3 for sucking colored liquid
A striped pattern is formed by suctioning and passing the dye solution in the direction of the arrow when it matches the direction of the arrow. In this case, the interval between each visit of the striped pattern approximately corresponds to the interval in the circumferential direction of the grooves 8 and through holes 15 in the colored liquid outflow hollow drum 2 and the sleeve 14. In this way, a plurality of slivers 22 are simultaneously colored and formed into a sheet shape. In particular, in this device, a hydrophilic treated slit plate block 11 is inserted and fixed into the groove 8 with the flow hole 7 of the hollow drum 2 for discharging the colored liquid.
The colored liquid flowing out from the main shaft 5 of the hollow drum 2 and reaching the slit plate block 11 is held between the slits of the slit plate block 11 by capillary action and at the same time rapidly diffuses in the length direction. Therefore, of the main shaft 5,
Even if the outflow of the colored liquid in the axial direction is uneven, the colored liquid can be maintained uniformly, and when this uniformly held colored liquid matches the grooves 8 and the slit-like through holes 15, the colored liquid is colored. The liquid passes through the sliver 22 due to the negative pressure of the liquid suction hollow drum 3, and coloring without uneven coloring is realized. At this time, the slit plate block 11
The partition plate 10 exhibits a guiding function for proper flow of the colored liquid sucked by the negative and positive of the hollow drum 3 and flowing down.

As described above, according to this embodiment, the negative pressure inside the colored liquid suction hollow drum 3 forces the coloring liquid to pass through the fibers such as the wool sliver 22 to color the thick fibers. However, since it can be colored as is and there is no need to use a conventional gill, the feeding speed of textiles is not restricted by the use of gills, and the coloring speed of textiles can be greatly increased. Furthermore, since no gill is used, it is possible to ground-dye textiles such as Sliver 22 and apply them to the above device while still wet to form striped patterns, making it easy to continue the process from ground-dying to forming striped patterns. It will become possible to realize this. At this time, since the striped pattern is formed using negative pressure, an additional effect is obtained in that the striped pattern does not bleed even if the textile product remains wet. Furthermore, since both drums 2.3 and sleeve 14 are made of stainless steel and do not compress and harden over time like felt, they do not have the disadvantage of becoming less colored even after long-term use. Does not occur. In particular, according to this embodiment, the grooves 8 of the colored liquid outflow hollow drum 2, the through holes 15 of the sleeve 14, and the slit-shaped flow holes 7a of the drum 3
Coloring can be done by simply supplying a sufficient amount of coloring liquid into the hollow drum 2 for coloring, which reduces the amount of coloring liquid used and reduces the negative impact. Since coloring is carried out using pressure and by uniformly retaining the colored liquid by the slit plate block 11 in the groove 8, coloring without uneven coloring can be achieved.

In the above embodiments, stainless steel is used as the material for the slit plate block, but the material is not limited to this, and any type may be used as long as it has wood-friendly properties and appropriate rigidity. Further, although the hollow drum 2 for colored liquid outflow is disposed on the upper side and the hollow drum 3 for colored liquid suction is disposed on the lower side, these may be disposed upside down, or they may be disposed horizontally. Good too. In addition, instead of driving the sleeve 14 of the drum 3 with the motor 18 and using the driving force to feed the sliver 22 or other textile product, the sliver 22 or other textile product is pulled from the front side in the feeding direction, and the tensile force is used to pull the sliver 22 or other textile product from the front side in the feeding direction. You may also send it. Furthermore, in the above embodiment, the main shaft 5 is fixed,
The hollow drum 2 is rotationally driven around it, but the 8th
As shown in the figure, a hole 12 is provided on the entire outer peripheral surface of the main shaft 5, and the main shaft 5 is attached to the shaft holder 4 with a bearing 6 interposed therebetween. The main shaft 5 may be rotationally driven by being connected to the liquid pipe 24, and the hollow drum 2 may be rotated along with the rotation. In addition, 5e is a mechanical seal,
5f is a bearing. Further, as shown in FIG. 9, nozzles 25 are inserted into the name tags 16 of the hollow main shaft 5 of the hollow drum 2 for discharging the colored liquid, so that the colored liquid supplied into the main shaft 5 is evenly distributed from the nozzles 25. It is also possible to allow the colored liquid to fall (if the nozzle 25 is not provided, the colored liquid may travel along the main shaft 5 and fall from one place in the form of raindrops). moreover,
The grooves 8 and the holes 15 are not formed parallel to the axial direction as in the above embodiment, but as shown in FIG.
It may also be formed in an axially inclined state. Also, the first
As shown in FIG. 1, a plurality of holes 26 may be provided in a continuous state, each forming a groove and a through hole.

In the above embodiment, the wool sliver 22 is to be colored, but the present invention is not limited thereto, and can be applied to natural fibers such as silk, cotton, and hemp, and synthetic fibers such as polyester, nylon, acrylic, and rayon. It is intended to color a wide range of single or mixed fibers, and its shape may be not only sliver but also top, wrap, web, etc.

〔Effect of the invention〕

Since the textile coloring apparatus of the present invention is configured as described above, even thick textiles can be colored as they are, and there is no need to pass through a gill as in the conventional method. Therefore, the inconvenience that the coloring speed is restricted by the passing speed of the gills is avoided, and coloring such as striped patterns can be formed extremely quickly and efficiently. Furthermore, since no gil is required, it becomes possible to realize continuous operation with the ground dyeing equipment used in the previous process. Furthermore, since this device does not use a felt roll as in the past, the coloring does not fade due to changes in the felt roll over time, and can provide stable and homogeneous coloring over a long period of time. In addition, this device can convert multiple large string-like fiber products such as slivers into sheets at the same time as forming striped patterns, and can accurately form striped patterns. It is also possible to form a multicolored striped pattern by installing them in multiple stages. In particular, this device has a plurality of slit plates in the coloring grooves of the hollow drum for coloring liquid suction, so that the coloring liquid is uniformly distributed within the grooves by capillary action, resulting in uniform coloring without unevenness. This is a major feature.
