Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a textile coloring method and apparatus for coloring and forming a pattern such as a striped pattern on a textile product such as sliver.

[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 Bigolo textile printing apparatus 30 includes a printing paste box 32 provided on a mounting base 31,
A liquid supply roll 33 is disposed within the printing paste box 32, and at the same time, a felt roll 34 is provided in pressure contact with this liquid supply roll 33, and furthermore, an engraving roll 35 is disposed opposite to this felt roll 34. 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. The web 40 is then passed between the felt roll 34 and the engraving roll 35 to be printed with the printing paste supplied from the printing paste box 32, and this is wound up by the first and second winding rolls 41, 42, and further, A shaking plate 43 that swings from side to side is designed to shake off the product onto a product table 44. The printing using the felt roll 34 and the engraving roll 35 is performed as shown in FIG.
A felt roll 34 placed opposite the roller is impregnated with printing paste, and a sheet-like web 40 is passed between the felt roll 34 and an engraving roll 35 having a spiral ridge 45 on its outer peripheral surface. This is done by printing a 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 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 apparatus is equipped with a gill 36, and since this gill 36 cannot pass the ground-dying sliver containing moisture, it is difficult to integrate the above-mentioned apparatus 30 with the sliver ground-dying process. It's impossible.

(Problems to be solved by the invention) As mentioned above, the conventional Vigoro printing equipment has problems in coloring efficiency and homogeneous printing, and also has problems in ground dyeing and continuous printing for textile products such as sliver. In particular, in the field of Bigolo textile printing, technological innovation is lagging behind other dyeing processing fields, and there is a strong desire to solve the above problems.

The present invention was developed 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 object of the present invention is to provide a method and apparatus for coloring textiles that can be realized.

Means for Solving Problem C] In order to achieve the above object, the present invention allows a textile product to pass between a hollow drum for discharging a colored liquid and a hollow drum for sucking a colored liquid, which are arranged vertically oppositely, When the textile product passes through, the colored liquid is intermittently flowed out from the outer peripheral surface of the hollow drum for discharging the colored liquid, and at the same time, this flowing colored liquid is sucked by the hollow drum for suctioning the colored liquid, so that the textile product The first gist is a method for coloring textiles in which the textiles are colored at appropriate intervals by passing through a hollow drum for discharging the colored liquid and a hollow drum for suctioning the colored liquid, with gaps for the textiles to pass through. The drums are arranged one above the other, and each of the drums is provided with a passage hole for the colored liquid in the opposing portion thereof, and a plurality of through holes are formed at predetermined intervals in the circumferential direction on the outer periphery of each of the two drums. A sleeve provided thereon is rotatably fitted onto the outside, and a synchronizing means is provided for synchronizing the rotation of both sleeves so that the plurality of through holes of both sleeves are sequentially aligned with the communication holes of both hollow drums at the same timing. The second gist is a textile coloring device.

That is, the present invention, like the conventional Bigolo printing,
Printing is not simply carried out by printing, but by forcing the colored liquid to flow through the interior of the sliver or other textile product by draining the colored liquid from one drum and suctioning it from the other drum. Since it is a coloring device, even thick textiles can be directly colored. 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. moreover,
Since felt rolls are not used as in the past, 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 FIG. 2 shows a longitudinal section thereof. In these figures, reference numeral 1 denotes a pair of left and right metal frames, and on this frame 1, a hollow drum 2 for discharging a colored liquid and a hollow drum 3 for sucking a colored liquid, both made of stainless steel, are vertically and oppositely arranged in a fixed state. There is. As shown in FIG. 2, the two drums 2.3 are provided with slit-shaped communication holes 4.degree. 4a extending in the axial direction, as shown in FIG. Hollow drum 2 for outflowing the colored liquid
A colored liquid outflow sleeve 5 and a colored liquid suction sleeve 6 made of stainless steel are rotatably fitted around the outer periphery of the colored liquid suction hollow drum 3, respectively. is the slit-shaped flow hole 4, 4
A plurality of slits 7.7a having the same shape as a are formed at equal intervals in the circumferential direction. The colored liquid outflow sleeve 5 and the colored liquid suction sleeve 6 each have gears 8 and 8a that mesh with each other, and the gear 8a provided on the colored liquid suction sleeve 6 is connected to the rotating shaft 10 of the motor 9. It meshes with a provided gear 11 and is rotationally driven by the motor 9. As a result, both the sleeves 5, 6 are able to connect the plurality of sleeves (7, 7a) provided at predetermined intervals along the circumference on their respective outer peripheral surfaces to the communication holes 4, 7a of the hollow drums 2.3 at the same timing. 4a in order to coincide with the rotation.

The colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3 are fixed to main shafts 12 and 123, respectively.The main shaft 12 is fixed to a shaft holder 13 of the frame 1, and the main shaft 12a is fixed to the frame 1. Fixed. The sleeves 5, 6 fitted around the outer circumferences of the hollow drums 2.3 are attached to the main shafts 12, 12a via bearings 14.14a, and rotate around the outer circumferences of the hollow drums 2.3. The main shaft 12 of the colored liquid outflow hollow drum 2 is
The interior is hollow, and a colored liquid containing dyes and pigments as main components is supplied thereto via a pipe 12b by a constant flow liquid pump (not shown).
The main shaft 12a of the colored liquid suction hollow drum 3 is also hollow inside, and a vacuum pump (
(not shown). Both axles 12, 123 above
As shown in Figure 2, holes 15 are provided at appropriate intervals.
,．． 15a is provided, and the colored liquid sent through the pipe 12b flows down from the hole 15 of the main shaft 12 into the hollow drum 2 for flowing out the colored liquid, and this flowing liquid is transferred to the above-mentioned sleeve 7.7a and the communication hole. 4° When matching with 4a, the suction force of the vacuum pump connects the communication hole 4 - slit 7 - communication hole 4a.
→It is fed into the colored liquid suction hollow drum 3 via the slit 7a, then fed into the main shaft 12a via the hole 15a, and discharged from there to the outside. This discharged liquid is replenished with colorant as appropriate and is again supplied from the hollow drum 2 for colored liquid discharge. In addition, 16 is a body with an adjustment handle that raises and lowers the shaft holder 13 and adjusts the gap between both sleeves 5.6.

In this configuration, by rotating the motor 9, the two gears 8
, 8a are rotated in the direction of the arrow, and several to dozens of wool slivers 17 are passed in parallel between both sleeves 5 and 6 for coloring (FIG. 3). In this case, each sliver 17 maintains its thick string-like shape until it enters between both slits 7.7a, but is formed into a substantially flat sheet-like shape by the pressure applied when passing between both sleeves 5.6. As shown in FIG.
4a, a striped pattern is formed by suctioning and passing the dye solution in the direction of arrow A. In this case, the distance between each movement of the striped pattern approximately matches the distance between the slits 7.7a in both sleeves 5, 6 in the circumferential direction. In this way, a plurality of slivers 17 are simultaneously colored and formed into a sheet shape.

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 17 to color the thick fibers. It also becomes possible to easily uniformly color the inside. In particular, according to this embodiment, each time the slit 7 of the sleeve 5 and the slit-shaped flow hole 4 of the drum 2 match, an amount of the colored liquid sufficient for the coloring is caused to flow out. Coloring can be done simply by flowing into the hollow drum 2, which reduces the amount of coloring liquid used, and because the coloring is done using negative pressure, uniform coloring can be achieved. Moreover, in this embodiment, a plurality of slivers 17 can be formed into a sheet by passing a textile article such as the sliver 17 between the slits 7.7a under pressure.
It also has the effect of forming a striped pattern and simultaneously converting the textile into a sheet. In addition, in this example, even thick textiles can be colored as is, and there is no need to use a gill like in the past, so the feeding speed of textiles is not restricted by the use of gills, and the coloring speed of textiles can be greatly increased. can be increased. Furthermore, since there is no need to use a gill, it is possible to ground-dye textiles such as Sliver 17 and apply them to the above device while still wet to form a striped pattern. It is possible to easily realize this. At this time, since the amount of colored liquid used to form the striped pattern is small and negative pressure is used, the striped pattern does not bleed even when the textile is wet. Effects can be obtained. In addition, both the drums 2 and 3 and the sleeves 5 and 6 are made of stainless steel and do not compress and harden over time like felt, so the degree of coloring may become lighter even after long-term use. This will not cause any inconvenience.

In the above embodiment, the colored liquid outflow hollow drum 2 is disposed on the upper side and the colored liquid suction hollow drum 3 is disposed on the lower side, but these may be disposed upside down or horizontally. It may be placed in In addition, the sleeves 5 and 6 of both drums 2.3 are
Instead of driving the sliver 17 with the motor 9 and using the driving force to send the sliver 17 or other textile product, the sliver 17 or other textile product may be pulled from the front side in the feeding direction and sent using the tensile force. Furthermore, in the above embodiment, the main shaft 12.
The main shaft 12, 122 is made hollow and the colored liquid is supplied or suctioned from there.As shown in FIG.
122 as the exposed shaft, and by removing the side wall surfaces of both sleeves 5.6 on the opposite side from the gears 8, 8a, the side wall surfaces of both hollow drums 2.3 are exposed, and the outflow holes 18 are formed in each of the exposed side wall surfaces. And suction holes 19 may be provided, and the ends of the colored liquid outflow pipe 18a and the colored liquid suction pipe 19a may be fitted into these holes 18 and 19, respectively, to perform outflow or suction of the colored liquid. Also, the 6th
As shown in the figure, a nozzle 20 is fitted into each hole 15 of the hollow main shaft 12 of the hollow drum 2 for colored liquid outflow, and the colored liquid supplied into the main shaft 12 is evenly distributed and falls from the nozzle 20 (the nozzle 20 (If there is no coloring liquid, the colored liquid may travel along the main axis and fall like raindrops from one place.) Furthermore, the slits 7.7a may be formed at an angle in the axial direction, as shown in FIG. 7, instead of being parallel to the axial direction as in the above embodiment. Furthermore, as shown in FIG. 8, a plurality of holes 21 may be provided in a continuous manner to serve as a substitute for the slit 7.7a. Therefore, in the present invention, the coloring liquid flow holes 4.4a of both hollow drums 2.3 for coloring liquid outflow and suction, and both sleeves 5.
26 plurality of slits 7.7a are slits, round holes,
It includes a wide range of holes such as long holes.

In addition, in the above embodiment, the wool sliver 17 is targeted for coloring, but the present invention is not limited to this.
, natural fibers such as silk, cotton, linen, polyester, nylon,
It is intended for coloring a wide range of synthetic fibers such as acrylic and rayon, singly or as a mixture, and the shape thereof may be not only sliver but also top, wrap, web, etc.

[Effects of the Invention] As described above, the present invention provides an intermittent flow from the hollow drum for discharging the colored liquid when passing a textile product such as a sliver between the hollow drum for discharging the colored liquid and the hollow drum for suctioning the colored liquid. At the same time as the coloring liquid flows out, the coloring liquid is sucked from the hollow drum for coloring liquid suction, so even thick textiles can be colored as they are.
There is no need to go through the gil process. Therefore, the inconvenience that the coloring speed is regulated by the passing speed of the gill process is avoided, and it becomes possible to form colored patterns such as striped patterns at extremely high speed and efficiently. Furthermore, since the gill process is no longer necessary, it becomes possible to realize continuity with the ground dyeing process, which is the previous process. Furthermore, since the present invention does not use a felt roll as in the past, the phenomenon of color fading due to changes in the felt roll over time does not occur, and stable and homogeneous coloring can be achieved over a long period of time.

Further, the device of the present invention has a hollow drum for discharging the colored liquid and a hollow drum for suction, which are arranged vertically opposite each other, and a circulation hole is bored in the opposing portions of both drums, and a circumferential direction is formed on the outer periphery of both drums. A sleeve with a plurality of slits is rotatably fitted on the outside of the sleeve, and in order to synchronize the rotation of both sleeves so that the slits of both sleeves sequentially align with the circulation holes of both hollow drums at the same timing, a thick sleeve is used. It is possible to accurately form a striped pattern even on a textile product, and it is also possible to form a plurality of thick string-like textile products such as slivers into a sheet at the same time as forming the striped pattern.

Furthermore, since this device can form striped patterns at precisely predetermined intervals, it is also possible to install this device in multiple stages to form multicolored striped patterns. Moreover, gills are no longer required, and the coloring speed can be increased, while connection to a background dyeing device is possible.
