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 Bigolo 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 within the printing paste box 32, and at the same time, a felt roll is brought into pressure contact with this liquid supply roll 33. 34 is provided, and furthermore, an engraving roll 35 is provided opposite to this felt roll 34. And the mounting base 31
A gill 36 in which a large number of needles are planted in a distributed manner is provided, and the sliver 38 is pulled out from inside a plurality of cans 37 and arranged in parallel with a rotating roll 39. The sliver 38 is passed through the gill 36 to form a sheet-like web 40, and then The printing paste supplied from the printing paste box 32 is passed between the felt roll 34 and the engraving roll 35 for printing, and is wound around the first and second winding rolls 41 and 42, and is then rolled up on the left and right sides. A shaking plate 43 that vibrates shakes the product onto a product stand 44. The felt roll 34 and the engraving roll 3
5, as shown in FIG. 12, a felt roll 34 placed opposite to an engraving roll 35 is impregnated with printing paste, and an engraving roll 35 having a spiral convex strip 45 on the outer peripheral surface is used. This is done by passing a sheet-like web 40 between them and printing a diagonal striped pattern 46 by pressing the spiral protrusions 45.

This type of Bigolo printing equipment has a long history and has been used for producing marbled worsted yarn.
5 and the felt roll 34, -
The textile product is stretched considerably thin after printing twice. Therefore, even if a plurality of sets of the engraving rolls 35 and felt rolls 34 were provided to perform multicolor printing, it could not be carried out because the textile would be cut midway. Furthermore, since printing on thick textiles is a national problem, the apparatus 30 must first pass the sliver 38 through the gill 36 to form a sheet before printing. Therefore, even if an attempt is made 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 restricted (the mechanism of the gill makes it unsuitable for high-speed operation; It also has the disadvantage that the printing efficiency cannot be increased beyond a certain limit due to the fact that the felt of the felt roll 34 is compressed and hardened with continued use. As a result, the amount of printing paste absorbed is reduced, and if used for a long period of time, the color of the print becomes lighter.In addition, the printing target is limited to dry textiles. , 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.
6, and since this gill 36 cannot pass the ground dyeing sliver containing moisture, the above-mentioned device 3
0 cannot be made continuous with the sliver dyeing process.

[Problem that the invention seeks to solve]

As mentioned above, the conventional Vigolo printing apparatus has problems in multicolor single coloring efficiency and homogeneous printing, and also problems in ground dyeing and continuous printing of textile products such as sliver. 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 a textile product such as sliver with striped patterns using multiple colors, and it is also suitable for the background dyeing process of textile products. The purpose is to provide a method for coloring textiles that can be continuous.

[Means for solving problems]

In order to achieve the above object, the method of the present invention is to feed a textile product by using a hollow drum for discharging a colored liquid having an outflow hole on the outer circumferential surface and a hollow drum for suctioning the colored liquid having a suction hole on the outer circumferential surface in a facing state. A plurality of sets are arranged in parallel in the direction, and the textile product is sequentially passed between the colored liquid outflow hollow drum and the colored liquid suction hollow drum in the plurality of sets, and when the textile product passes between the two drums, each The colored liquid of a predetermined color is flowed out from the outflow hole of the hollow drum for coloring liquid outflow, and at the same time, the outflowing colored liquid is sucked through the suction hole of the hollow drum for coloring liquid suction, and the textile product is colored at a predetermined interval. The structure is to apply the following.

That is, the method of the present invention does not use an engraved roll and a felt roll to perform printing by printing, as in the conventional Vigoro printing apparatus, but uses a hollow drum for colored liquid discharge and a hollow drum for colored liquid suction. A plurality of sets of drums are used, and a textile product such as sliver is passed between the two drums in the plurality of sets, and during this passage, a colored liquid of a predetermined color is flowed out from the outflow hole of the hollow drum for outflow. Coloring is carried out by sucking out the colored liquid through the suction hole of the hollow suction drum and forcing the colored liquid to pass through the inside of the textile, such as sliver, so multi-colored coloring can be achieved. Furthermore, thick textiles can also be directly colored. Therefore, unlike in the past, there is no need to use a gill, so there is no restriction on the feed speed of textiles due to passing through a gill, and it is possible to significantly improve coloring efficiency. Striped patterns can be formed even on textiles, and continuous ground dyeing and pattern coloring can be achieved. Furthermore, since there is no need to use felt rolls, 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 multicolor coloring apparatus for textiles used in an embodiment of the present invention, and FIG. 2 shows a cross section taken along line A-A. 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. Reference numeral 50 denotes a base, and on its upper surface, three sets of drums J and units U each consisting of a frame 11 and two hollow drums 2.3 are arranged side by side along the direction of feeding of textile products as shown by arrow B. In each of the above units U, the colored liquid outflow hollow drum 2 is rotatably attached to the main shaft 5 fixed to the shaft holder 4 of the frame 1 via a bearing 6, and is configured to rotate in the circumferential direction. It has become. This hollow drum 2 has a plurality of grooves 8 on its outer circumferential surface having colored liquid flow holes 7 at the groove bottom.
are formed at predetermined intervals in the circumferential direction, and each of the grooves 8 is provided with a plurality of long slit plates 9 made of stainless steel, as shown in FIG. A slit plate block 11 has short partition plates 10 erected at predetermined intervals, 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. It is inserted and fixed. The slit plate 9 and the partition plate IO have surface oils and fats removed by alkali treatment, and subsequently (acid treatment) to form irregularities on the surface to increase their affinity for water. As shown in FIG. 2, the drum 3 is rotatably attached to a main shaft 5a fixed to the frame 1 via a bearing 6, and rotates in the circumferential direction. A plurality of colored liquid suction grooves 13 (see Fig. 4) are formed on the surface at predetermined intervals in the circumferential direction, and are paired with the lower communication hole 12. Communication hole 1
2 through a colored liquid circulation hole 14, and one end of the communication hole 12 opens as a suction opening 15 in the mirror-finished surface of one side of the colored liquid suction hollow drum 3. 1
Reference numeral 6 denotes a suction cylinder made of polyfluoroethylene that is connected to a vacuum pump (not shown), and the fixing metal fitting 1 is attached so that the cylinder opening slides into the vicinity of the top of one side of the hollow drum 3.
6a, and the suction opening 15 in the communication hole 12 of the colored liquid suction hollow drum 3, which has reached the colored liquid passing gap 3a, matches the cylinder opening of the hollow drum 3, and the suction force of the vacuum pump is applied to the communication hole 3a. It does not extend to the suction groove 13 communicating with the hole 12.

This suction groove 13 is filled and fixed with a polyvinyl formal sponge for preventing dust from entering. The colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3 each have gears 17 and 173 that mesh with each other, and the gear 17a provided on the colored liquid suction hollow drum 3 is It meshes with a gear 20 that is rotationally driven by a motor (hidden and cannot be seen) and is rotationally driven by the motor. 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.

The hollow main shaft 5 is connected to the hollow main shaft 5 via a pipe (not shown).
A constant flow liquid pump (
(not shown), and as mentioned earlier, the colored liquid suction hollow drum 3 is supplied with oisoba.
Due to its rotation, the coloring liquid suction groove 13 is vacuumed by a vacuum pump through the communication hole 12 every time the coloring liquid suction groove 13 is located in the textile article passing gap 3a.

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 8. The colored liquid reaches the groove 8 from the flow hole 7 and is held uniformly in the longitudinal direction of the groove 8 by capillary action between the slit 1 and the slit plate 9 of the plate block 11, and is attracted to the groove 8. Groove 13
When the groove 8 degrees and the suction groove 13. Flow hole 14. It is discharged to the outside from the suction cylinder 16 via the communication hole 12. This discharged liquid is replenished with colorant as appropriate and is again supplied to the hollow main shaft 5 of the hollow drum 2 for discharging the colored liquid. In this case, for each unit,
The hues of the colored liquids are set to be different.

The above-mentioned three sets of units U each having a frame 12 and hollow drums 2.3 are arranged by a known tuning mechanism (not shown) so as not to overlap and color the same part of the textile product. Hollow drum 2.3, each unit) U
The rotary drive is synchronized between the two. Also, the coloring position of the first unit U)
To change the phase of coloring, such as changing the coloring position of U,
A known differential gear (hidden and invisible) is provided in the base 50 for each unit U.

In addition, 23 is a screw 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. Also, 51
(Drum units listed above with textiles before coloring)
A feed roller 52 feeds the colored textiles into U, and a feed roller 52 feeds out the colored textiles, both of which rotate freely.

In this configuration, the motor is rotated to drive the gears 17, 172 of each drum unit U to rotate in the direction of the arrow, and the wool sliver 24 is inserted into the gap 3a between the colored liquid outflow hollow drum 2 and the colored liquid suction hollow drum 3. Coloring is done by passing several to dozens of strips in parallel (Figure 5). In this case, each sliver 24 maintains a large string-like shape 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 the figure, when the grooves 8 of the colored liquid outflow hollow drum 2 and the suction grooves 13 of the suction hollow drum 3 match, the colored liquid passes through each unit U by suction in the direction of the arrow. A striped pattern of a different color is formed each time.

In this case, the formation interval of the striped pattern of a certain color and the formation position of the striped pattern of another color relative to the striped pattern of a certain color are determined by the same 3J1 mechanism and differential gear, etc. It can be easily adjusted by operation. In this embodiment, in order to form a striped pattern of three colors, the first unit U forms stripes a (see FIG. 5) constituting the striped pattern of a certain color at predetermined intervals, and then Unit 2) (In J, form the stripes of another color with the ground part left between the stripes a, and then in the third unit U, form the stripes of another color. Since the stripes C that make up the pattern are formed with a ground portion left between the stripes and the stripes A, the striped pattern stripes in three colors are regularly formed on the sheet-like textile product after coloring. A beautiful color pattern is formed as a whole.

In this way, the sliver 24 is formed into a sheet and is colored in multiple colors to give it a beautiful color pattern. In particular, in this device, the colored liquid is vacuum-suctioned by creating colored liquid suction grooves 13 at appropriate intervals on the outer periphery of the suction drum 3, instead of vacuum suctioning the entire drum by making the entire suction drum hollow. Since this suction groove 13 is provided and vacuum suction is performed through the communication hole 12, good suction can be achieved without increasing the degree of vacuum, thereby achieving multi-colored coloring without uneven coloring. It has a soothing effect.

In this way, since this embodiment performs coloring using the negative pressure of the communication hole 12 as described above, a plurality of units l-U are arranged in parallel as described above, and each unit U Different coloring at °ζ does not cause the textile to be cut, and has the excellent effect of easily forming multiple striped patterns with mutually different hues on the textile. It is a characteristic. Furthermore, according to this embodiment, even thick textiles can be colored as is, there is no need to use a conventional gill, and 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 to Furthermore, since no gill is used, it is possible to ground-dye textiles such as Sliver 24 and apply them to the above device while still wet to form striped patterns, making it easy to continue the process from ground-dying to forming striped patterns. It will become possible to realize this. 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.

Furthermore, since both the 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. Furthermore, according to this embodiment, the grooves of the hollow drum 2 for discharging the colored liquid? ! 48 and the suction groove 13 of the suction drum 3, coloring can be done by simply flowing out an amount of coloring liquid sufficient for the coloring into the hollow drum 2 for flowing out the coloring liquid. In addition to using less coloring liquid, since the coloring is effectively carried out using negative pressure, it is possible to achieve coloring without uneven coloring.

FIG. 7 shows another embodiment. In this embodiment, a hydrophilic polyvinyl formal sponge 25 having continuous pores is inserted and fixed in the grooves 8 of the hollow drum 2 for discharging the colored liquid. The rest is the same as the embodiment shown in FIG.

The polyvinyl formal sponge 25 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 25 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 86-92%, and the degree of formalization is 70-90%, preferably 80-86%.
It is most preferred to use a polyvinyl formal sponge. This embodiment has the same effects as the previous embodiment, and also has a polyvinyl formal sponge 25 inserted and fixed into the groove 8 with the flow holes of the hollow drum 2 for discharging the colored liquid. The colored lacquer flowing out from the main shaft 5 of the drum 2 is held uniformly in the polyvinyl formal sponge 25 having continuous pores, and this uniformly held colored liquid is transferred to the groove 8 and the hollow suction drum 3. When the sliver matches the suction groove 13, the sliver passes through the sliver 24 due to the negative pressure of the colored liquid suction hollow drum 3, and as a result, uniform coloring without uneven coloring is achieved.

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. It may also be placed horizontally. In addition, the drums 2 and 3 are connected to the motor 18.
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 grooves 8 and the suction grooves 13 are not formed parallel to the axial direction as in the above embodiment, but are formed in the eighth direction.
As shown in the figure, it may be formed in an axially inclined state. 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 object of coloring, but the present invention is not limited thereto, and can be applied to natural fibers such as silk, cotton, and hemp, 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. In addition, in the above embodiment, striped pattern stripes a, b, and c of three colors are formed at equal intervals.
As shown in FIG. 10(a), the streaks a, b, and c may be formed without any intervals, and the set consisting of the streaks a, b, and c may be formed repeatedly at appropriate intervals. However, as shown in FIG. 1O(b), a set of streaks a, b, and c may be formed repeatedly without leaving any appropriate intervals. Alternatively, as shown in FIG. 10(C), the lines a and b may be formed without any interval between them, and the line C may be formed a little apart from this, and this process may be repeated. Furthermore, the striped pattern need not be of three colors but may be of only one color as shown in FIG. 10(d).

In this case, since the streaks a are formed by a plurality of units U, the streaks a can be formed densely per unit area, making it possible to obtain a dense pattern.

〔Effect of the invention〕

As described above, the method for coloring textiles of the present invention uses a plurality of sets of hollow drums for suctioning a colored liquid and hollow drums for discharging a colored liquid, and uses one set of hollow drums for sucking a colored liquid. Since the coloring liquid discharged from the hollow drum for coloring liquid outflow is colored by passing through the textile article using pressure, multi-colored coloring can be achieved without cutting the textile article. Therefore, a plurality of striped patterns of mutually different colors can be easily formed in a composite state. Further, according to this method, 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. Additionally, since no gil is required, it becomes possible to connect the process with the ground dyeing equipment used in the previous process.
Furthermore, since there is no need to 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.
