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 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 inside the printing paste box 32, and at the same time, a felt l is placed in pressure contact with this liquid supply roll 33. −
A roll 34 is provided, and an engraving roll 35 is further provided opposite to this felt roll 34. And the above mounting base 3
1 is provided with a gill 36 in which a large number of needles are planted in a distributed manner, and the sliver 38 is pulled out from inside a plurality of cans 37 and arranged in parallel with a rotating roll 39, and then passed through the gill 36 to form a sheet-like web 40. Then felt roll 34
The printing paste supplied from the printing paste box 32 is passed through between the printing paste box 32 and the engraving roll 35 for printing, and is wound up by the first and second winding rolls 41 and 42, and then the shaking plate moves left and right. 43, it is shaken off onto a product table 44. The felt roll 34 and the engraving roll 3
5, as shown in FIG. 11, the felt roll 34 placed opposite to the engraving roll 35 is impregnated with printing paste, and the engraving 1 call having a spiral convex strip 45 on the outer peripheral surface is used. This is done by passing a sheet-like web 40 between the ridges 35 and 35, and printing a diagonal striped pattern 46 by pressing the spiral ridges 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 feeding speed of the sliver 38 to increase the printing efficiency, the speed is naturally regulated through the gill 36 (the gill is mechanically unsuitable for high-speed operation, and in high-speed operation where it can be operated, the fibers etc. The problem is that the printing efficiency cannot be increased beyond a certain limit because the printing efficiency cannot be increased beyond a certain limit.Furthermore, in the Vigolo printing apparatus 30, the felt of the felt roll 34 is compressed and hardened with continued use. Therefore, the amount of absorption of the printing paste is small (and when used for a long period of time, the color tone of the printing becomes lighter).
0 is because 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 water-containing ground dyeing sliver, it is impossible to integrate the device 30 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 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 practical textile coloring device.

[Means for solving problems]

In order to achieve the above object, in the textile coloring device of the present invention, a hollow drum for discharging a coloring liquid and a hollow drum for sucking a coloring liquid are arranged vertically and freely rotatably across a gap through which the textiles pass. The hollow drum for outflowing the colored liquid is equipped with a
A plurality of colored liquid outflow holes are bored at predetermined intervals in the circumferential direction on the outer circumferential surface, and a plurality of colored liquid suction grooves are formed on the outer circumferential surface of the hollow drum for colored liquid suction at predetermined intervals in the circumferential direction. A plurality of suction openings each communicating with the plurality of colored liquid suction grooves are formed at predetermined intervals in the circumferential direction on one side of the hollow drum for colored liquid suction. The suction portions of the suction means are brought into sliding contact so as to sequentially align with the suction openings of the colored liquid suction grooves that arrive at the textile article passing gap between both hollow drums, thereby preventing the plurality of colored liquids from flowing out of the colored liquid flowing hollow drums. A configuration is adopted in which a synchronizing means is provided for synchronizing the rotation of both the hollow drums so that the holes and the plurality of colored liquid suction grooves of the hollow drum for colored liquid suction are aligned sequentially through the above-mentioned textile article passing gap. .

In other words, the apparatus of this invention does not simply perform printing by printing like the conventional Vigoro textile printing apparatus, but uses a hollow drum for colored liquid discharge and a hollow drum for colored liquid suction, and a space between the two drums. is passed through a textile product such as a sliver, and during this passage, the colored liquid flows out from the outflow hollow drum, and the outflowing colored liquid is sucked by a suction hollow drum, and the colored liquid is applied to the textile product such as a sliver. Since coloring is performed by forcing the inside of the product to pass through, 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 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 colored liquid outflow hollow drum 2 is rotatably attached to the main shaft 5 fixed to the shaft holder 4 of the frame l via a bearing 6.
It is designed 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 a colored liquid flow hole 7 at the bottom of the groove.
In each of the grooves 8, a plurality of long stainless steel slit plates 9 were arranged in parallel, as shown in FIG. 3, and short stainless steel partition plates 10 were erected at predetermined intervals. A slit plate block 11 is fitted and fixed with the slit plate 9 side facing the groove bottom and the longitudinal direction of the slit plate 9 aligned with the longitudinal direction of the groove 8. The slit plate 9 and the partition plate IO are subjected to an alkali treatment to remove surface oils and fats, and a subsequent acid treatment to form irregularities on the surface to increase their affinity for water. Further, the colored liquid suction hollow drum 3 is attached to a frame 1 as shown in FIG.
It is rotatably attached via a bearing 6 to a main shaft 5a fixed to the main shaft 5a, and rotates in the circumferential direction. On the outer peripheral surface of the hollow drum 3, a plurality of colored liquid suction grooves 13 (see FIG. 4), which are paired with the lower communication hole 12, are formed at predetermined intervals in the circumferential direction. The above colored liquid suction groove 1
3 and the communication hole 12 are communicated with each other by a colored liquid circulation hole 14, and one end of the communication hole 12 is opened as a suction opening 15 in the mirror-finished surface of one side of the hollow drum 3 for colored liquid suction. 16 is a suction cylinder made of polyfluoroethylene connected to a vacuum pump (not shown), and its cylinder opening is
The communicating hole 12 of the colored liquid suction hollow drum 3 is fixed by 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 colored liquid suction hollow drum 3 reaches the colored liquid passing gap 3a.
Match the suction opening 15 with the cylinder mouth of itself,
The suction force of the vacuum pump is applied to the suction groove 13 communicating with the communication hole 12. This suction groove 1
3 is filled and fixed with polyvinyl formal sponge to prevent 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 that mesh with each other,
A gear 17a provided on the colored liquid suction hollow drum 3,
It meshes with a gear 2o provided on a rotating shaft 19 of the motor 18 and is rotationally driven by the motor 18.

As a result, the colored liquid outflow hollow drum 2 and the suction hollow drum 3 rotate synchronously so that the plurality of grooves 8 and the suction grooves 13 are sequentially aligned with each other through the textile article passage gaps 3a. The main shaft 5 of the colored liquid outflow hollow drum 2 is a hollow shaft, and holes 21 are formed at appropriate intervals in the axial direction on the lower side thereof. A nozzle 22 is inserted into each of these holes 21, and the colored liquid supplied into the main shaft 5 is evenly distributed and falls (if there is no nozzle 22, the colored liquid may travel along the main shaft 5 and start from one place). It is designed to cause raindrops to fall. On the other hand, the main shaft 5a of the colored liquid suction hollow drum 3 is a bare shaft.

A vibrator (not shown) is connected to the hollow main shaft 5.
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 12. As a result, the colored liquid fed into the hollow main shaft 5 of the colored liquid outflow hollow drum 2 flows down from the hole 21 of the main shaft 5 into the colored liquid outflow hollow drum 2, and then at the bottom of the groove of the strip/lI8. The colored liquid reaches the groove 8 from the flow hole 7 and the slit plate block 11
The grooves 8 are held uniformly in the longitudinal direction between the slit plates 9 by capillary action, and when the grooves 8 and the suction grooves 13 match, the suction force of the vacuum pump causes the grooves 8 to be held uniformly. Suction/#13, circulation hole 14. It is discharged to the outside from the suction cylinder 16 via the communication hole 12. This discharged liquid is refilled with coloring agent as appropriate and then refilled with the hollow main shaft 5 of the hollow drum 2 for discharging the colored liquid.
supplied to

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

In this configuration, when the motor 18 is rotated, both the gears 17. i7a is rotated in the direction of the arrow to open the gap 3 between the colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3.
Coloring is performed by passing several to several dozen wool slivers 24 in parallel through a (FIG. 5). In this case, each sliver 2
4 maintains the shape of a large string until it enters the gap 3a, but is formed into a substantially flat sheet shape by the pressure applied when passing through the gap 3a, and as shown in FIG. 6, When the grooves 8 of the colored liquid outflow hollow tram 2 and the suction grooves 13 of the suction hollow drum 3 match, the colored liquid is suctioned and passed in the direction of arrow A, thereby forming a striped pattern.

In this case, the interval between each visit of the striped pattern almost matches the interval in the circumferential direction between the grooves 8 and the suction grooves 13 in the colored liquid outflow hollow drum 2 and the suction hollow drum 3. In this way, a plurality of slivers 24 are simultaneously colored and formed into a sheet shape. especially,
In this device, the vacuum suction of the colored liquid is not performed by making the entire suction drum hollow and vacuum suctioning the entire drum, but by providing colored liquid suction grooves 13 at appropriate intervals on the outer periphery of the suction drum 3. Since this suction groove 13 is vacuum-suctioned through the communication hole 12, good suction can be achieved without increasing the degree of vacuum, thereby achieving the effect of coloring without uneven coloring. play.

As described above, according to this embodiment, the negative pressure in the communication hole 12 communicating with the suction groove 13 forces the coloring liquid to pass through the fibers such as the wool sliver 24 to color the thick fabric. It is possible to color textile products as they are, there is no need to use gills as in the past, there is no restriction on the feeding speed of textile products due to the use of gills, and the coloring speed of textile products can be greatly increased. Moreover, since it does not use gil,
A striped pattern can be formed by ground-dying a textile product such as the sliver 24 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, since both drums 2 and 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 after long-term use. In particular, according to this embodiment, each time the groove 8 of the hollow drum 2 for outflowing the colored liquid matches the suction groove 13 of the hollow drum 3 for suction, it is sufficient for the coloring to occur once. Coloring can be done simply by supplying the star coloring liquid into the hollow drum 2 for coloring liquid outflow, which reduces the amount of coloring liquid used, and because the coloring is done effectively using negative pressure, uneven coloring can be avoided. This makes it possible to achieve coloring that is completely invisible.

FIG. 7 shows another embodiment. This embodiment is based on the structure of the hollow drum 2 for discharging the coloring liquid. ? 48, a hydrophilic polyvinyl formal sponge 25 having continuous pores is inserted and fixed. The rest is the same as the embodiment shown in FIG. The above-mentioned polyvinyl formal sponge 25 is made by combining polyvinyl alcohol with starch as a pore-forming agent, a mineral acid catalyst, and formalin (?H) to form a polyvinyl alcohol marl, and then washing with water and adding starch, a mineral acid catalyst, etc. It is manufactured by removing it by washing with water, and the pores are the traces of starch elution.This polyvinyl formal sponge 2
No. 5 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 colored liquid. From this point of view, the porosity is 70 to 95%, preferably 86 to 92%,
Formalization degree is 70-90%, preferably 80-8
Most preferably, a 6% polyvinyl formal sponge is used. This embodiment has the same functions and effects as the previous embodiment, and in addition, a polyvinyl formal sponge 25
is inserted and fixed, the colored liquid flowing out from the main shaft 5 of the hollow drum 2 is uniformly held in the polyvinyl formal sponge 25 having continuous pores, and this uniformly held colored liquid is transferred to the above-mentioned condition. When the groove 8 matches the suction groove 13 of the hollow drum 3 for suction, the colored liquid is caused to pass through the sliver 24 due to the negative pressure of the hollow drum 3 for suction.
As a result, it is possible to realize uniform coloring without uneven coloring.

In the above embodiments, the colored liquid outflow hollow drum 2 is arranged on the upper side and the colored liquid suction hollow drum 3 is arranged on the lower side, but these may be arranged upside down. However, it may be placed horizontally. In addition, the drums 2 and 3 are connected to the motor 1.
8 and using the driving force to send the sliver 24 or other textile product, the sliver 24 or other textile product may be pulled from the front side in the feeding direction and sent using the tensile force. Furthermore, the formation of the grooves 8 and the suction grooves 13 is
Instead of being parallel to the axial direction as in the above embodiment, it may be formed to be inclined in the axial direction, as shown in FIG. Alternatively, as shown in FIG. 9, a plurality of holes 26 may be provided in a continuous manner to form grooves and suction grooves, respectively.

In the above embodiment, the wool sliver 24 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. Moreover, this device can simultaneously form striped patterns on a large set of multiple fiber products, such as slivers, and form striped patterns accurately. It is also possible to form a multicolored striped pattern by installing them in multiple stages. In particular, this device does not make the hollow drum for suctioning a colored liquid hollow and suction the colored liquid by suctioning the entire hollow drum, but instead creates colored liquid suction grooves at appropriate intervals on the outer periphery of the suction drum. Since the suction grooves are used to create suction, good suction can be achieved without having to increase the suction force very much, and as a result, it is possible to achieve uniform coloring without uneven coloring, which is a major feature. be.
