Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a pour dyeing method for thread rolls such as cheese or corn.

(Conventional technology) Conventionally, the pour dyeing method for skeins was developed, for example, by
It is known from the publication No. 50-16472.

In other words, the conventional pour-dye dyeing method targets skeins, and uses a frame body that has a plurality of dye solution injection chambers (mold holes) that are partitioned by partition plates and open on the top and bottom surfaces. The skeins placed on the net body are brought into contact with the lower surface, and the skeins are dyed by injecting the dye liquid into the dye liquid injection chamber through the opening on the upper surface by a pressure method or a vacuum method.

(Problems to be Solved by the Invention) However, the pour dyeing method using skeins has the following problems.

In other words, in the case of skeins, as shown in A in Figure 2, the traverse period is limited because the winding width is narrow despite the long winding length, and the dyed portion of the thread when dyed with width H is , as shown by reference numeral 8 in FIG. 2A,
It was short and could not be made longer. In addition, when winding a skein, even if the yarn is a bulky yarn such as a crimped yarn, the winding density of the yarn cannot be freely controlled in the case of a skein. During dyeing, it was not possible to freely control the pitch of the dyed pattern on the yarn.

(Means for Solving the Problems) The object of the present invention is to solve the drawbacks of the above-mentioned skein pouring dyeing method, and has the following configuration. That is, a spool of cheese or corn is brought into contact with the lower surface of a frame having a plurality of dye liquid injection chambers partitioned by partition plates and open at the upper and lower surfaces,
In the pour dyeing method, in which the dye liquor is injected into the dye solution injection chamber through the upper opening to dye the thread, the thread is compressed into a flat shape with the core removed. This is a pour dyeing method for thread rolls.

The inventors of the present invention have discovered that the above-mentioned drawbacks of the skein can be overcome by using a spool of cheese, corn, or the like wound around a core. In other words, in the case of a wound material such as cheese or corn, the traverse period of the thread can be freely changed as shown in Fig. 2B, and the dyed portion of the thread when dyed with width H is As shown by reference numeral 9 in FIG. 2B, it can be long, or it can be shortened. It has also been found that there are advantages in that the winding density can be freely controlled during winding, and the pattern pitch can also be arbitrarily controlled by the winding density of the yarn.

However, even if you try to use the pour dyeing method on cheese or corn, it cannot be carried out as it is.

In the present invention, we have discovered that pour-dye dyeing can be performed by first removing the core of cheese or corn and dyeing it while compressing it into a flat shape.

FIG. 1 is a schematic diagram showing a method of pouring dyeing a wound material such as cheese or corn according to the present invention.

In FIG. 1, reference numeral 1 denotes a plain frame body, within which a plurality of partition plates 2 are arranged in a zigzag pattern.
The upper and lower surfaces are open, and a plurality of dye liquid injection chambers 3 formed by the above-mentioned partition plates are formed in the frame in a juxtaposed manner. Reference numeral 4 denotes a bed made of a mesh body, on which cheese or corn 5 is placed and brought into contact with the lower surface of the dye liquid injection chamber 3. 6 indicates a pressurizing machine, and 7 indicates a vacuum machine.

During the textile printing work, the dye solution injection chamber 3 is arranged with respect to a plurality of cheeses or corns 5 so that each partition plate 2 constituting the dye solution injection chamber 3 is arranged in a direction that intersects with the axial direction of the cheese or corn. Place it on the
A desired dye solution is injected into each of the dye solution injection chambers 3, and the dye solution is rapidly permeated using a known pressure method or vacuum method to prevent adjacent dye solutions from mixing with each other to create a pattern. It is used for dyeing.

In the present invention, it is necessary to flatten the cheese or corn by compression during the dyeing described above. That is, by making the cheese or corn into a flat state, the dyeing solution directly penetrates from the layer A side to the layer B side of the cheese or corn, and the desired pattern pitch can be dyed.

This cheese or corn can be made into a flat state by the action of a pressure machine 6 and a vacuum machine 7 during injection of the dye solution.

On the other hand, if the cheese or corn is not flattened but dyed in a cylindrical state with the core removed, the dye solution will not penetrate from the A side to the B side of the cheese or corn, and the C Alternatively, the dye liquor may flow into the D side, causing color mixing or a difference in color shading between the inner layer and the outer layer.

It is preferable to flatten the cheese or corn to the extent that the A side and the B side of the cheese or corn are in direct contact with each other, but in the case of bulky yarn, the gap between the A side and the B side is Although it depends on the pressure and vacuum conditions, dyeing is possible even at a length of about 80 mm. Therefore, the gap between the A side and the B side can be generally 80 mm or less, preferably 30 mm or less, and more preferably 15 mm or less. Even if the A side and the B side have the above-mentioned gap, the dye solution permeates from the A side to the B side because they are under pressure or vacuum.

In the present invention, not only bulky yarn but also cotton,
Natural fiber yarn such as hemp, cotton yarn (human silk), synthetic fiber,
Needless to say, it can be applied to fine count yarn and thick yarn.

In the present invention, if the cheese or corn becomes flat after dyeing and does not recover to its original state, a member that can forcibly expand and contract in the circumferential direction by applying the principle of a bat umbrella is installed on the winding core. By inserting it into the removed part, the cheese or corn can be restored to its original shape.

FIG. 3 is a perspective view showing another example of the arrangement of cheese or corn 5 during dyeing. That is,
As shown in FIG. 3, the cheese or corn 5 may be arranged in a different direction than in the example of FIG. 1, for example perpendicular to that of FIG.

In the present invention, since the core of the cheese or corn is dyed with the core removed, the yarn in the inner layer may become disordered, resulting in poor unwinding performance when unwinding the yarn from the dyed cheese or corn. There are cases. If these unwinding defects occur, for example, it is preferable to insert the tubular knitted fabric into the through hole of the winding core before dyeing.

4A, B, and C are examples in which the tubular knitted fabric is inserted into the core of cheese or corn, and in FIG. 4A, the tubular knitted fabric 11 is inserted before the core 10 is removed. Fig. 4B shows a state in which the winding core 10 is removed and the tubular knitted fabric 11 is folded back at both end faces of the cone or cheese to cover the cheese surface from both ends with the tubular knitted fabric. In this state, dyeing is carried out, and as shown in FIG.
The yarn can be wound with good unwinding properties without causing any disturbance in the yarn in the inner layer.

(Effects) As described above, the present invention replaces the conventional dyeing with skeins and enables injection dyeing with cheese or corn, thereby producing the following excellent effects.

(a) The traverse cycle and winding density of the yarn can be freely controlled, and therefore the pattern pitch of the yarn can be varied over a wide range.

(b) In addition, there is no color mixing and a high quality product can be obtained.

(c) Compared to skein dyeing, there is no need to rewind (cone or cheese wrap) after dyeing, and the product can be submitted to the next processing in that state after dyeing, which can shorten the process and dyeing delivery time. .

(d) In the case of skein dyeing, long fibers, bulky textured yarns, non-twisted yarns, etc. are difficult to unravel after dyeing and cannot be put to practical use; however, in the present invention, even these yarns can be used without any problems. be able to.

(E) In addition, in the case of skein dyeing, fine count spun yarn may cause yarn breakage during skeining or winding.
Further, although it is impractical because it takes a long time, the present invention can be used without any problem even with these threads.
