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 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. 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 to produce 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 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 feasible method for coloring textile products.

[Means for solving problems]

In order to achieve the above object, the method for coloring textiles of the present invention includes one drum in which a plurality of circulation grooves each having a coloring liquid retaining material are formed at predetermined intervals on the outer circumferential surface, and a corresponding drum in the other drum. drums are arranged opposite to each other with a gap for passing through the textiles in between, and while rotating at least one of the drums, the textiles are passed through the gap for passing through the textiles, and the textiles pass between the two drums. In this case, the coloring liquid that has been injected into the distribution groove and held by the coloring liquid holding material is transferred to the textile product by blowing compressed gas into the distribution groove to color the textile product. Take.

In other words, the method of the present invention does not simply perform printing by printing using an engraved roll and a felt roll, as in the conventional Vigolo printing apparatus, but rather a plurality of circulation grooves are formed on the outer circumferential surface at predetermined intervals. A textile product such as sliver is passed between the two drums, and during this passage, the distribution groove of the one drum is Since coloring is performed by forcibly transferring the coloring liquid held in the coloring liquid holding material to the textile by the pressure of pressurized gas, 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 it is possible to achieve a significant improvement in coloring efficiency. Also,
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 example of a textile coloring apparatus used in an embodiment of the present invention, and FIG. 2 shows a longitudinal section thereof. In these figures, ``■'' indicates a pair of left and right metal frames, and one drum 2 and the other drum 3 made of stainless steel are vertically disposed opposite to each other on this frame 1. One of the drums 2 is attached to a main shaft 5 which is rotatably fixed to a shaft holder 4 of the frame 1 via a bearing 6, and rotates together with the main shaft 5 in the circumferential direction. This one drum 2 has two sets of grooves 8 on its outer circumferential surface, each having a colored liquid flow hole 7 at the groove bottom, and each set of grooves is point symmetrical about the main shaft 5. A hydrophilic polyvinyl formal sponge 9 having continuous pores is inserted and fixed in the groove 8 . The polyvinyl formal sponge 9 is made by mixing polyvinyl alcohol with starch as a pore-forming agent, a mineral acid catalyst, and formalin to formalize the polyvinyl alcohol, and then washing it with water to remove the starch, mineral acid catalyst, etc. 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 70-95%
, preferably 86 to 92%, with a degree of formalization of 70
It is most preferred to use ~90% polyvinyl formal sponge, preferably 80-86%. Reference numeral 10 denotes a communication passage with a closed end provided below the groove 8 as a pair with the groove 8, and communicates with the groove 8 through the coloring liquid flow hole 7. The rear end of this communication path 10 opens to the mirror-finished surface of one side of one of the drums 2, and when the opening 11 and the supply cylinder 12 match, the colored liquid is applied to the opening 11 from the supply cylinder 12. It is designed to be injected under pressure. The opening edge of this opening 11 is formed in a flange lla, and prevents the colored liquid injected under pressure from returning from the opening 11. As the drum rotates, the injected colored liquid passes through the communication holes 7 and is retained in the communication holes of the polyvinyl formal sponge 9. The above supply cylinder 1
2 is made of polyfluoroethylene resin and is provided on the upper part of one of the shaft holders 4, and its cylindrical opening is connected to a portion near the top of one side of the one drum 2 (the opening 11 of the communication path 10 that has reached the top). (corresponding part)). 16a is its fixing metal fitting. 13 is a pressurized air supply cylinder for expelling the colored liquid held in the polyvinyl formal sponge 9; (a portion corresponding to the opening 11).

16b is its fixing metal fitting. The supply cylinder 13 is also made of the same material as the supply cylinder 12 and is fixed to the lower part of the shaft holder 4. To explain the supply cylinders 12 and 13 in more detail, a colored liquid containing dyes and pigments as main components is supplied to the supply cylinder 12 under pressure by a constant flow liquid pump (not shown). . This constant flow liquid delivery pump uses the drive motor 22 as a drive source for its own piston, and the motor 22, a reduction gear mechanism (not shown), and a reciprocating motion that converts rotational motion into linear motion. The piston is reciprocated by the rotational movement of the motor 22, and the colored liquid is supplied to the supply cylinder]2.
It is designed to be supplied to Further, compressed air is supplied to the pressurized air supply cylinder 13 by a compression pump (not shown). Each of the supply cylinders 13 is provided with a solenoid valve 14 near its end, which is opened and closed by a cam switch 15. This cam switch 15 is provided at the tip of the extension of the main shaft 5 and faces the outer peripheral surface of a disc 16 that interlocks with the main shaft 5, and its own trochanter F is pressed by the protrusion 18 of the disc 16. It turns on when pressed, and turns off when the pressure is released. As shown in FIG. 3, the protrusions 18 are formed on the outer circumferential surface of the disk 16 in the same number as the grooves 8 and at intervals corresponding to the intervals at which the grooves 8 are formed. When the communicating passages 10 of the grooves 8 reach the uppermost and lowermost positions of one drum 2, they press the rotor 17 of the switch 15. As shown in FIGS. 1 and 2, the other drum 3 corresponding to the one drum 2 is composed of a pair of left and right disc-shaped side plates and a cylindrical stainless steel Mi419 mounted between the two side plates. , is rotatably attached to a main shaft 5a fixed to the frame 1 via a bearing 6a. 7a is a reinforcing cylinder provided between both side plates. 28 due to the presence of the reticular body 19,
It is a colored liquid receiving tray that receives the colored liquid that passes through the drum 3 and flows down to the lower side thereof, and is adapted to return the received colored liquid to the supply cylinder 12 via a storage tank (not shown) in order to reuse it. There is. 21 and 212 are gears provided on the one drum 2 and the other drum 3, and are in mesh with each other. That is, the gear 13 provided on the other drum 3
a is a gear 23a provided on the rotating shaft 23 of the motor 22
The drums 2 and 3 are meshed with each other and rotated by the motor 22, thereby causing the one drum 2 and the other drum 3 to rotate at the same circumferential speed.

In addition, 25 is a body with a handle, which raises and lowers the shaft holder 4 and adjusts the gap 3a between one drum 2 and the other drum 3.

In this configuration, the motor 22 is rotated to rotate both the gears 21 and 213 in the direction of the arrow, and one drum 2
Coloring is performed by passing several to several dozen wool slivers 18 in parallel through the gap between the drum 3 and the other drum 3 (Fig. 4).
. In this case, each sliver 18 maintains a large set-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,
As shown in FIG. 2, when the groove 8 of one drum 2 reaches the gap 3a and the groove 'a8, which is point symmetrical to it, reaches the top of the drum 2, the opening 11 of the communication path 10 and The respective cylinder openings of the supply cylinders 12 and 13 match, and a predetermined amount of colored liquid of a predetermined color is injected from the supply cylinder 12 into the communication passage 10 from a constant flow liquid sending pump, and this injection liquid is transferred to the drum. As it rotates, it passes through the flow hole 7 and is held by the polyvinyl formal sponge 9. On the other hand, when the opening 11 of the communication passage 10 and the cylinder openings of the supply cylinders 12 and 13 are aligned, the cam switch 15 is turned on, the solenoid valve 14 is temporarily opened, and the pressurized air is discharged from the pressurized air supply cylinder 13. , compressed air is sent into the communication path 10, and due to its pressure, the colored liquid held in the polyvinyl formal sponge 9 is transferred to the sheet-shaped sliver 2 passing through the gap 3a, as shown in FIG.
4 forcibly as shown by arrow A and colored. By repeating this, a striped pattern can be continuously formed on the sliver 24. The colored liquid after coloring passes through the mesh body 19 in the direction of arrow B and reaches the other drum 3.
The colored liquid flows down as shown by arrow C and collects in the colored liquid receiver 28.
It is then offered for reuse.

As described above, according to this embodiment, the coloring liquid is discharged by the compressed air pressure in the communicating path 10 communicating with the groove 8, and is forcibly passed through the inside of the textile product such as the wool sliver 24 to color it. Therefore, even thick textile items can be colored as is.
There is no need to use a conventional gill, and the feeding speed of textile products is not restricted by the use of gills, and the coloring speed of textile products can be greatly increased. Furthermore, since no gill is used, textiles such as Sliver 24 can be ground-dyed and hung on the above device while still wet to form a striped pattern.
It becomes possible to easily realize the continuous process from ground dyeing to striped patterning. At this time, since the striped pattern is formed using the pressure of compressed air, an additional effect is obtained in that the striped pattern does not bleed even when the textile is wet. Furthermore, since both of the drums 2.3 are made of stainless steel and do not compress and harden over time unlike felt, they do not cause problems such as the degree of coloring becoming lighter even when used for a long period of time. In particular, according to this embodiment, the grooves 8 of one of the drums 2 and the pressurized air supply cylinder 13 are aligned via the communication path 10.
Coloring can be done by simply supplying a sufficient amount of coloring liquid from the supply cylinder 12 into the communicating path IO, which is point-symmetrical to the communicating path 10, for each coloring, and the amount of coloring liquid used is small. Not only does it require a lot of effort, but since the coloring is done effectively using pressure, it is possible to achieve coloring without uneven coloring.

In the above embodiment, the drum 3 is made of a net-like body 19 made of stainless steel, but the drum 3 is not limited to this. Alternatively, as long as the coloring liquid can flow out smoothly, a drum that is simply cylindrical without the mesh or the like may be used. Further, in the above embodiment, both the one drum 2.3 and the other drum 2.3 are rotated, but the outer peripheral surface of the other drum 3 has a distribution length corresponding to the groove 8 of the one drum 2. If a sleeve in which a hole is formed is rotatably fitted onto the outside, and the sleeve is driven to rotate so that the long circulation holes of this sleeve coincide with the grooves 8 of the one drum 2, the other drum 2 can be rotated. The drum 3 may remain fixed. Further, in the above embodiment, one drum 2 is arranged on the upper side and the other drum 3 is arranged on the lower side, but these may be arranged horizontally. Also, the drum 2.3 is connected to the motor 22.
Instead of driving the sliver 24 and other textile products using the driving force, it is also possible to pull the sliver 24 and other textile products from the front side in the feeding direction and send the textile products using the pulling force. Furthermore, the formation of the stripes 18 is not parallel to the axial direction as in the above embodiment, but as shown in FIG.
It may be formed to be inclined in the axial direction, or as shown in FIG. 7, a plurality of holes 26 may be provided in a continuous state and the grooves 8 may be formed. Further, in the above embodiment, the wool sliver 24 is the object of coloring, but the present invention is not limited thereto, and may be applied to natural fibers such as silk, cotton, linen, and polyester.

It can be used to color a wide range of synthetic fibers such as nylon, acrylic, and rayon, singly or in combination, and the shape thereof may be not only sliver but also top, wrap, web, etc.

〔Effect of the invention〕

Since the method for coloring textile products of the present invention is configured as described above, even thick textile products can be directly colored, 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 method does not use a felt roll as in the conventional method, the phenomenon of color fading due to changes in the felt roll over time does not occur, and it is possible to achieve stable and homogeneous coloring over a long period of time. It is possible to form a plurality of large string-like fiber products, such as slivers, into a sheet at the same time as forming a striped pattern.
