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. Such dry printing 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,
At the same time, a liquid supply roll 33 is disposed in the printing paste box 32, and at the same time, it is pressed against the liquid supply roll 33 to
Further, an engraving roll 35 is provided 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 3I, and the sliver 38 is pulled out from inside a plurality of cans 37, aligned 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 shaker 43 that swings from side to side is used to shake off the product onto a product table 44. The stamping by the felt roll 34 and the engraving roll 35 is performed as shown in FIG.
5 is impregnated with printing paste, and the sheet-like web 4o is passed between the felt roll 34 and the engraving coal 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 3o 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 above-mentioned Vigolo printing apparatus 3o, the felt of the felt roll 34 is compressed and hardened with continued use, so the amount of printing paste absorbed is small. It also has the following drawbacks.Furthermore, the above-mentioned device 3
o, since the printing target is limited to dry textiles,
It cannot be continuous with the coloring process in which textiles are pre-ground dyed, and this is an impediment to creating a continuous line for ground dyeing and printing. That is, the above device includes a gill 36,
Since this gill 36 cannot pass the ground dyeing sliver containing moisture, it is impossible to integrate the above-mentioned apparatus 3o with the sliver ground dyeing process.

[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 textiles such as slivers. 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.

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.

[Failure to solve the problem]

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 porous body having continuous pores is inserted and fixed in the grooves, and the colored liquid suction hollow drum is provided with a coloring liquid circulation hole in a portion opposite to the colored liquid outflow hollow drum. A sleeve having a plurality of through holes bored at predetermined intervals in the circumferential direction is rotatably fitted on the outer periphery of the sleeve, and the plurality of grooves of the hollow drum for discharging the colored liquid and the plurality of through holes of the sleeve are rotatably fitted on the outer periphery of the sleeve. A configuration is adopted in which a synchronizing means is provided for synchronizing the rotations of the hollow drum for discharging the colored liquid and the sleeve so that the holes sequentially align with the flow holes of the hollow drum for sucking the colored liquid at the same timing.

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 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 made of stainless steel are vertically arranged 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 peripheral surface, each having colored liquid flow holes 7 at the groove bottom, and the grooves 8 have continuous pores. A hydrophilic polyvinyl formal sponge 9 is inserted and fixed therein. The above-mentioned polyvinyl formal sponge 9 is made by combining polyvinyl alcohol with starch as a pore-forming agent, a mineral acid catalyst, and formalin to form a polyvinyl alcohol formal, washing with water, and adding starch as a pore-forming agent with a mineral acid catalyst and formalin. It is manufactured by washing and removing starch, and the pores are the traces of starch elution. This polyvinyl formal sponge 9 has a coloring liquid retention function, and has appropriate hydrophilicity to the extent that the color can be easily washed away with water when changing the coloring liquid. From this point of view, the porosity is 70 to 95%, preferably 86 to 92%.
%, the degree of formalization is 70-90%, preferably 8
Most preferably, a 0-86% polyvinyl formal sponge is used. 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 10 is fitted onto the outside so as to be rotatable in the circumferential direction. A slit-shaped communication hole 7a extending in the axial direction is bored in a portion of the colored liquid suction hollow drum 3 facing the colored liquid outflow hollow drum 2, and the outer periphery of the colored liquid suction sleeve 10 A plurality of slit-shaped through holes 1) extending in the axial direction are bored in the surface at the same intervals as the formation intervals in the circumferential direction of the grooves 8 in the hollow drum 2 for discharging the colored liquid. The main shaft 5 of the colored liquid outflow hollow drum 2 has a hollow interior, and a pipe 5b is inserted into the main shaft 5.
dye.

A colored liquid containing pigment as a main component is supplied by a constant flow liquid pump (not shown), and the main shaft 5a of the hollow drum 3 for sucking the colored liquid is also hollow inside. and is connected to a vacuum pump (not shown) through a pipe 5C. The above-mentioned amphiphilic shafts 5 and 5a each have a second
As shown in the figure, holes 12 and 123 are provided at appropriate intervals, and the colored liquid sent through the pipe is passed through the main shaft 5.
The coloring liquid is allowed to flow down from the hole 12 into the hollow drum 2 for flowing out,
Next, the colored liquid reaches the inside of the groove 8 from the groove bottom 7 of the groove 8 and is held by the polyvinyl formal sponge 9, and this retained liquid is transferred to the groove 8 and the slit-shaped through hole 1).
When the grooves 8 are aligned with the communication holes 7a, the grooves 8 are opened by the suction force of the vacuum pump.

It is fed into the colored liquid suction hollow drum 3 via the slit-shaped through hole 1) and the circulation hole 7a, and then fed to the main shaft 5a via the hole 12a and discharged from there to the outside. The discharged liquid is replenished with colorant as appropriate and is again supplied to the hollow drum 2 for discharging the colored liquid. The hollow tram 2 for discharging colored liquid and the sleeve 10 for suctioning colored liquid each have gears 13 and 133 that mesh with each other. It meshes with a gear 16 provided on a rotating shaft 15 and is rotationally driven by a motor 14. As a result, the colored liquid outflow hollow drum 2 and sleeve 10 have a plurality of grooves 8 and ? The M number of through holes 1) rotate synchronously so as to sequentially align with the communication holes 7a of the hollow drum 3 at the same timing.

Reference numeral 17 denotes a body with a handle, which raises and lowers the shaft holder 4 to adjust the gap between the colored liquid outflow hollow drum 2 and the colored liquid suction sleeve 10.

In this configuration, when the motor 14 is rotated, both the gears i3. +3a is rotated in the direction of the arrow, and several to dozens of wool slivers 18 are passed in parallel through the gap between the colored liquid outflow hollow drum 2 and the colored liquid suction sleeve 10 for coloring (Fig. 3). ). In this case, each sliver 18 maintains a large string-like shape until it enters the above-mentioned gap, but is formed into a substantially flat sheet-like shape by the pressure applied when passing through the above-mentioned gap, and as shown in Fig. 4. As shown, the grooves 8 of the colored liquid outflow hollow drum 2 and the through holes 1 of the sleeve 10
Hollow tube for colored liquid suction L, 3 slit-shaped flow hole 7
A striped pattern is formed by suctioning and passing the colored liquid in the direction of the arrow when the color matches a. In this case, the intervals between each part of the striped pattern are as follows:
and grooves 8 and through holes 1 in the sleeve 10)
It almost matches the circumferential spacing of . In this way, a plurality of slivers 18 are simultaneously colored and formed into a sheet shape. In particular, in this device, since the polyvinyl formal sponge 9 is inserted and fixed in the groove 8 with flow holes of the hollow drum 2 for colored liquid outflow, the colored liquid flows out from the main shaft 5 of the hollow drum 2. is uniformly held in the polyvinyl formal sponge 9 having continuous pores, and when the uniformly held colored liquid matches the groove 8 and the through hole 1) with the flow hole 7a, the colored liquid suction hollow drum The negative pressure of 3 causes the sliver to pass through the sliver 18. As a result, uniform coloring without color unevenness can be achieved.

As shown in the figure, according to this embodiment, the negative pressure inside the hollow tram 3 for sucking the coloring liquid forces the coloring liquid to pass through the fibers such as the wool sliver 18 to color the thick fibers. Even products can be colored as they are, eliminating the need to use gil as in the past.

Therefore, the feeding speed of textile products is not restricted by the use of gills, and the coloring speed of textile products can be significantly increased.

Moreover, since there is no need to use Gil, Sliver 1
A striped pattern can be formed by ground-dying a textile product such as No. 8 and applying it to the above-mentioned apparatus in a wet state, and it becomes possible to easily realize a continuous process from ground-dying to forming a striped pattern. 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. In addition, both the drums 2.3 and the sleeve 10 are made of stainless steel and do not compress and harden over time like felt, so even if used for a long period of time, the degree of coloring will be light (inconvenient). In particular, according to this embodiment, the grooves 8 of the colored liquid outflow hollow drum 2 and the sleeve 1
For each coloring due to the matching of the through hole 1) with the slit-shaped flow hole 7a of the drum 3, enough star colored liquid for that coloring is simply flowed into the hollow drum 2 for coloring liquid outflow. Coloring can be done with a small amount of coloring liquid, less coloring liquid is used, and since the coloring is carried out using negative pressure and evenly holding the coloring liquid by the polyvinyl formal sponge 9 in the groove 8, there is no uneven coloring. Coloring can be achieved.

Although polyvinyl formal sponge 9 is used in the above embodiment, the material is not limited to this, and any type of porous material may be used as long as it has appropriate hydrophilicity. 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 IO of the drum 3 with the motor 14 and using the driving force to feed the sliver 18 or other textile product, the sliver 18 or other textile product is pulled from the front side in the feeding direction, and the tension force is used to pull the sliver 18 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 and the hollow drum 2 is driven to rotate around it. However, as shown in FIG. At the same time, the open side edge 5d of the main shaft 5 is connected to the fixed liquid sending pipe 20 by the rotary joint 19 to rotate the main shaft 5,
The hollow drum 2 may be rotated along with the rotation. Further, as shown in FIG. 6, nozzles 21 are attached to the name tag 12 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 and falls from the nozzle 21 (if the nozzle 21 is not provided, the colored liquid may travel along the main shaft 5 and fall from one place like a raindrop). It's okay. Furthermore, the grooves 8 and the through holes 1) 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. good. Alternatively, as shown in FIG. 8, a plurality of holes 22 may be provided in a continuous manner to form grooves and through holes, respectively.

In the above embodiment, the wool sliver 18 is the subject of coloring, but the present invention is not limited thereto, and can be applied to natural fibers such as silk, cotton, and linen, 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, in this device, a porous body having continuous pores is inserted and fixed in the coloring grooves of the hollow drum for coloring liquid suction, so that the colored liquid is held uniformly.
It is possible to achieve uniform coloring without uneven coloring, which is a major feature.
