Description

Description: TECHNICAL FIELD The present invention relates to a textile product coloring device for coloring and forming a pattern such as a striped pattern on a textile product such as a sliver.

[Conventional technology]

The formation of a striped pattern on a fiber product such as a sliver has hitherto been performed by vigolo printing, and the fiber product on which the striped pattern is formed is used for forming a marbling fabric or the like. Such bigolo printing is generally performed using an apparatus as shown in FIG. That is, the bigolo printing apparatus 30 is provided with a printing paste box 32 on a mount 31.
At the same time as disposing the liquid supply roll 33 in the printing paste box 32, at the same time as disposing the liquid supply roll 33, a felt roll 34 is provided in pressure contact with the liquid supply roll 33, and further, at the felt roll 34. Engraving roll 35
Are opposite to each other. Then, a gil 36 in which a large number of needles are distributed and planted is provided on the mount 31 and a plurality of cans 37 are provided.
The sliver 38 is pulled out from the inside and aligned in parallel by a rotating roll 39, which is put on the gil 36 to form a sheet-like web 40, and then the felt roll 34 and the engraving roll 3
The printing paste supplied from the printing paste box 32 is printed through the space 5 between the first and second winding rolls 4.
It is wound up by 1, 42, and is further shaken down on the product stand 44 by the shake-down plate 43 which swings left and right. The printing by the felt roll 34 and the engraving roll 35 is performed by impregnating the felt roll 34, which is opposite to the engraving roll 35, with a printing paste as shown in FIG. Engraving roll 3 with strip 45
It is carried out by passing a sheet-shaped web 40 between the sheet 5 and the sheet 5, and printing a diagonal stripe pattern 46 by pressing the spiral convex strip 45.

This kind of bigolo printing device 30 has a long history and has been favored for the production of marbled carded yarn. However, since it is difficult to print thick textiles, the sliver 38 is once passed through the gil 36. It must be made into a sheet and then used for printing. Therefore, even if an attempt is made to increase the feeding speed of the sliver 38 to increase the printing efficiency, the speed of passing the gil 36 is naturally restricted (Gill is not suitable for high speed operation due to the mechanism, and fiber etc. in high speed operation that can be operated). However, there is a drawback that the printing efficiency cannot be increased beyond a certain limit. Further, in the above-mentioned bigolo printing apparatus 30, since the felt of the felt roll 34 is compressed and hardened by the continued use, the absorption amount of the printing paste is reduced, and the tint of the printing becomes thin when used for a long time. It has some difficulties. Furthermore, the device 30 described above
Since the object of textile printing is limited to the textile products in a dry state, it cannot be continuous with the coloring process of preliminarily dyeing the textile products, which is an obstacle to the continuous line of textile dyeing and textile printing. That is, the apparatus is equipped with the gil 36, and the gil 36 cannot pass through the ground dyeing sliver containing water, so that the device 30 cannot be continuous with the ground dyeing process of the sliver. Is.

[Problems to be solved by the invention]

As described above, the conventional Vigolo printing apparatus has problems in coloring efficiency and uniform printing, and also has problems in continuous dyeing and continuous printing of textiles such as sliver. Especially in the field of this bigolo printing,
Technical innovation is delayed compared to other fields of dyeing processing, and it is strongly desired to solve the above problems.

The present invention has been made in view of the above circumstances, and can efficiently and uniformly color a striped pattern or the like on a textile product such as a sliver, and further, it is possible to continuously perform the textile dyeing process to the ground dyeing process. It is an object of the present invention to provide a fiber product coloring device that can be realized.

[Means for solving problems]

In order to achieve the above-mentioned object, the textile product coloring device of the present invention is configured such that the coloring liquid outflow hollow drum rotatable in the circumferential direction and the coloring liquid suction hollow drum in a fixed state allow the textile product to pass therethrough. The colored liquid outflow hollow drum, which is disposed above and below with a gap therebetween, has a plurality of grooved grooves formed on the outer peripheral surface thereof and having colored liquid circulation holes at the groove bottoms at predetermined intervals in the circumferential direction. A porous body having continuous pores is fitted and fixed in the groove, and a colored liquid suction hollow drum is provided with a colored liquid flow hole at a portion facing the colored liquid outflow hollow drum. A sleeve having a plurality of through holes formed in its outer periphery at predetermined intervals in the circumferential direction is rotatably fitted on the outer periphery of the sleeve, and a plurality of groove grooves of the colored liquid outflow hollow drum and a plurality of through holes of the sleeve are provided. While sucking the above colored liquid at the same timing for each hole A configuration that tuning means to tune the rotation of the hollow drum and the sleeve for the coloring liquid outlet so as to sequentially match the flow holes of the drum is provided.

That is, the apparatus of the present invention does not simply perform printing by printing as in the conventional Vigolo printing apparatus, but uses a colored liquid outflow hollow drum and a colored liquid suction hollow drum having a sleeve. A fiber product such as a sliver is passed between the drums, the colored liquid is discharged from the outflow hollow drum, and the colored liquid is sucked by the suction hollow drum to force the colored liquid into the inside of the fiber product such as the sliver. Since it is colored by passing through it, it is possible to directly color thick textiles. Therefore, unlike the conventional case, it is not necessary to use the gil, and the phenomenon of restricting the feeding speed of the fiber product due to passing through the gil does not occur, so that the coloring efficiency can be greatly improved. Further, since no gil is used, a striped pattern or the like can be formed even on a textile product which has been dyed with ground and is still wet, and continuous dyeing and pattern coloring can be achieved. Further, since feltrol is not used as in the conventional case, uniform coloring can be realized for a long period of time.

Next, the present invention will be described in detail based on examples.

〔Example〕

FIG. 1 shows an embodiment of a coloring device for textiles used in the present invention, and FIG. 2 shows a longitudinal section thereof. In these drawings, reference numeral 1 denotes a pair of left and right metal frames, and a stainless colored liquid outflow hollow drum 2 and a colored liquid suction hollow drum 3 are vertically arranged on the frame 1. The colored liquid outflow hollow drum 2 is rotatably attached to a main shaft 5 fixed to a shaft holder 4 of a frame 1 via a bearing 6 so as to rotate in a circumferential direction. On the outer peripheral surface of the hollow drum 2, a plurality of grooved grooves 8 having colored liquid circulation holes 7 at the groove bottom are formed at predetermined intervals in the circumferential direction, and the grooved grooves 8 have continuous pores. The hydrophilic polyvinyl format sponge 9 that it has is fitted and fixed. The polyvinyl formal sponge 9 is prepared by mixing polyvinyl alcohol with a starch as a pore-forming agent, a mineral acid catalyst and formalin to form polyvinyl alcohol into a formal, and then washing with water to remove starch, mineral acid catalyst and the like with water. It is produced by the method described above, and the traces of starch elution are pores. This polyvinyl formal sponge 9
Has a function of retaining the coloring liquid, and has an appropriate hydrophilicity such that the color can be easily washed off by washing with water when changing the coloring liquid. From this perspective,
Porosity 70-95%, preferably 86-92%, degree of formalization 70-90%, preferably 80-86.
It is most preferred to use% polyvinyl formal sponge. On the other hand, the colored liquid suction hollow drum 3 is fixed to the main shaft 5a fixed to the frame 1 in a non-rotatable state, and the colored liquid attached to the main shaft 5a via a bearing 6a on the outer periphery thereof. The suction sleeve 10 is externally fitted so as to be rotatable in the circumferential direction. A slit-shaped flow hole 7a extending in the axial direction is formed in the portion of the colored liquid suction hollow drum 3 facing the colored liquid outflow hollow drum 2.
And a plurality of slit-shaped through holes 11 extending in the axial direction on the outer peripheral surface of the colored liquid suction sleeve 10.
Of the groove 8 in the colored liquid outflow hollow drum 2,
The holes are formed at the same intervals as the formation intervals in the circumferential direction.
A main shaft 5 of the colored liquid outflow hollow drum 2 has a hollow inside, and a colored liquid containing a dye or a pigment as a main component is supplied to the main shaft 5 via a pipe 5b at a constant flow rate pump (not shown). ), And the inside of the main shaft 5a of the colored liquid suction hollow drum 3 is also hollow, and is connected to a vacuum pump (not shown) through a pipe 5c. Each of the two spindles 5 and 5a has a second
As shown in the figure, holes 12 and 12a are provided at appropriate intervals, and the coloring liquid sent through the pipe is fed to the main shaft 5
Through the hole 12 of the colored liquid into the hollow drum 2 for flowing out the colored liquid,
Then, it is made to reach the inside of the groove 8 from the coloring liquid flow hole 7 at the groove bottom of the groove 8 and held by the polyvinyl formal sponge 9, and this retaining liquid is held in the groove 8 and the slit-shaped through hole 1
1 and the circulation hole 7a are matched, the suction force of the vacuum pump is used to feed the colored liquid into the hollow drum 3 for sucking the colored liquid through the groove 8, the slit-shaped through hole 11, and the circulation hole 7a. It is adapted to be fed into the spindle 5a via 12a and discharged from there to the outside. The discharged liquid is appropriately replenished with a coloring agent and is supplied again to the colored liquid outflow hollow drum 2. The hollow drum 2 for flowing out the colored liquid and the sleeve 10 for sucking the colored liquid are gears 13, 13 that mesh with each other.
A gear 13a provided on the colored liquid suction sleeve 10 meshes with a gear 16 provided on a rotating shaft 15 of the motor 14 and is rotationally driven by the motor 14. As a result, in the colored liquid outflow hollow drum 2 and the sleeve 10, the plurality of groove grooves 8 and the plurality of through holes 11 are at the same timing, and the flow holes 7 of the hollow drum 3 are the same.
The tuned rotation is performed so as to sequentially match a.

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

In this configuration, the motor 14 is rotated to rotate the both gears 13 and 13a in the direction of the arrow, and several wool slivers 18 are provided in the space between the colored liquid outflow hollow drum 2 and the colored liquid suction sleeve 10. Through dozens of them are colored in parallel (Fig. 3). In this case, each sliver 18 maintains the shape of a thick string until it enters the gap, but it is formed into a substantially flat sheet by the pressure applied when passing through the gap, and FIG. As shown in FIG. 3, the groove 8 of the colored liquid outflow hollow drum 2 and the through hole 11 of the sleeve 10
Is a slit-shaped flow hole 7a of the hollow drum 3 for sucking the colored liquid.
A striped pattern is formed by the suction passage of the coloring liquid in the direction of arrow A when the above condition is met. In this case, the interval between the stripe-shaped stripes substantially matches the interval in the circumferential direction of the groove 8 and the through hole 11 in the colored liquid outflow hollow drum 2 and the sleeve 10. In this way, a plurality of slivers 18 are simultaneously colored as they are and formed into a sheet shape. In particular, in this apparatus, since the polyvinyl formate sponge 9 is inserted and fixed in the groove 8 with the through holes of the colored liquid outflow hollow drum 2, the coloring outflowed from the main shaft 5 of the hollow drum 2 is colored. The liquid is uniformly held in the polyvinyl formal sponge 9 having continuous pores, and when the uniformly held colored liquid is aligned with the groove 8 and the through hole 11 and the flow hole 7a, a hollow for sucking the colored liquid is obtained. The negative pressure of the drum 3 causes the drum 3 to pass through the sliver 18. As a result, uniform coloring without color unevenness can be realized.

As described above, according to this embodiment, the coloring liquid is forcibly passed through the textile product such as the wool sliver 18 by the negative pressure in the coloring liquid suction hollow drum 3 to be colored. However, you can color it as it is, and you do not need to use the conventional gills. Therefore, the coloring speed of the textile can be greatly increased without being restricted by the feeding speed of the textile due to the use of gil. In addition, since it is not necessary to use a gil, textile products such as sliver 18 can be ground-dyed and can be applied to the above device in a wet state to form a striped pattern, and the process from ground dyeing to striped patterning can be continued. Can be easily realized. At this time, since the striped pattern is formed by using a negative pressure, there is an additional effect that the striped pattern has less bleeding even when the fiber product remains wet. Further, since both the drums 2 and 3 and the sleeve 10 are made of stainless steel and do not compress and harden with time unlike felt, there is a problem that the degree of coloring becomes thin even when used for a long time. Does not happen. Particularly, according to this embodiment, each time the coloring is performed by the matching of the groove 8 of the hollow drum 2 for flowing out the colored liquid and the through hole 11 of the sleeve 10 with the slit-shaped flow hole 7a of the drum 3, the coloring is performed. A sufficient amount of the coloring liquid can be colored by flowing out into the coloring liquid outflow hollow drum 2, the coloring liquid used can be small, negative pressure is utilized, and the polyvinyl in the groove 8 is used. Since the coloring liquid is uniformly held by the formal sponge 9 for coloring, it is possible to realize coloring without color unevenness.

In addition, in the above-mentioned embodiment, the polyvinyl formal sponge 9 is used, but the invention is not limited to this, and any kind of porous body having appropriate hydrophilicity may be used. Further, although 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, they may be arranged upside down or horizontally. Good.
Further, the sleeve 10 of the drum 3 is not driven by the motor 14 to drive the fiber product such as the sliver 18, but the fiber product such as the sliver 18 is pulled from the front side in the feeding direction, and the pulling force is applied. You may send it. Further, in the above-mentioned embodiment, the main shaft 5 is fixed and the hollow drum 2 is driven to rotate around it, but as shown in FIG. 5, a hole 12 is provided in the entire outer peripheral surface of the main shaft 5 and a bearing 6 is interposed. The rotary side joint 5 connects the open side edge portion 5d of the main shaft 5 to the fixed liquid feed pipe 20 so that the main shaft 5 is rotationally driven. You may make 2 rotate. Further, as shown in FIG. 6, the nozzles 21 are fitted into the holes 12 of the hollow main shaft 5 of the colored liquid outflow hollow drum 2, respectively, and the color liquid supplied into the main shaft 5 is supplied to the nozzles 2.
1 may be evenly dispersed and dropped (without the nozzle 21, in some cases, the colored liquid travels along the main shaft 5 and drops like a raindrop from one place). Further, the grooves 8 and the through holes 11 may be formed in a state of being inclined in the axial direction, as shown in FIG. 7, instead of being parallel to the axial direction as in the above embodiment. . Further, as shown in FIG. 8, a plurality of holes 22 may be continuously provided to form a groove and a through hole, respectively.

Although the wool sliver 18 is targeted for coloring in the above embodiment, the present invention is not limited to this, and natural fibers such as silk, cotton and hemp, and synthetic fibers such as polyester, nylon, acrylic and rayon. A single product or a mixed product of fibers is widely used for coloring, and the shape thereof may be not only a sliver shape but also a top shape, a lap shape, a web shape or the like.

〔The invention's effect〕

Since the textile product coloring device of the present invention is configured as described above, it is possible to perform coloring even for thick textile products as it is, and there is no need to go through the gills as in the conventional case. Therefore, the disadvantage that the coloring speed is regulated by the passing speed of the gil is avoided, and the colored formation of a striped pattern or the like can be performed extremely rapidly and efficiently. Further, since the gil is not necessary, it is possible to realize the continuation with the ground dyeing device in the previous process. Further, this apparatus does not use felterol as in the prior art, and therefore, the phenomenon of lightening of coloring due to the change over time of felterol does not occur, and stable uniform coloring can be performed over a long period of time. In addition, since this device can form a plurality of thick cord-shaped fiber products such as sliver into a sheet at the same time as forming the striped pattern, and can accurately form the striped pattern, It is also possible to install multi-stages to form a multi-color striped pattern. In particular, in this device, a porous body having continuous pores is fitted and fixed in the coloring groove of the coloring liquid suction hollow drum so as to uniformly hold the coloring liquid, so that there is no unevenness in color. It is possible to make various coloring, which is a major feature.
