BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dyeing bobbin.

[0002]

2. Description of the Related Art Conventionally, when a stretchable yarn is dyed in a heated state in a dyeing apparatus, as shown in FIG. 6, a large number of dyeing holes b are formed in a peripheral wall a to have a high rigidity. The dyeing bobbin c formed of a cylindrical body was used.

[0003] The yarn d
To form a cylindrical yarn layer e for dyeing.

Generally, as shown in FIG. 7 and FIG.
Has a small hole h from which the staining liquid is discharged.
Are provided upright.

[0005] Then, a ring-shaped spacer j and the yarn layer e are stacked on the spindle i so that they are alternately fitted.

Therefore, the small holes h ...
Is discharged from the dyeing hole b of the bobbin c to dye the yarn d.

[0007]

[Problems to be solved by the invention] Yarn d having elasticity
Is dyed in a heated state, the yarn layer e shrinks.

In this case, the middle to outer peripheral portion P of the yarn layer e contracts, but since the bobbin has high rigidity, the yarn at the inner peripheral portion Q near the peripheral wall a cannot be contracted and is dyed in a state where the yarn is extended. The yarn count is out of order, and the elasticity of the yarn is lost.

For this reason, yarns having different counts or having lost elasticity have been discarded as defective products.

[0010] Further, in the inner peripheral portion Q, there is another problem that the spaces between the yarns become too dense, the dyeing solution does not penetrate, and the dyeing becomes insufficient.

The present invention solves such a problem and prevents the yarn from elongating and deviating in yarn count at the inner peripheral portion Q of the yarn layer and preventing poor dyeing. Conventionally, the inner peripheral portion Q must be discarded. An object of the present invention is to provide a staining bobbin that eliminates unnecessary waste.

[0013]

The yarn is wound around the outer peripheral wall of the dyeing bobbin constructed as described above while leaving both ends slightly, thereby forming a cylindrical yarn layer to be dyed.

However, when the yarn layer is dyed in a heated state, when the yarn layer contracts, the spring-like transverse bone on the vertically elastically deformed fence wall of the dyeing bobbin is compressed, and the circumferential surface of the dyeing bobbin is reduced. Shrinks radially.

Therefore, the yarn around the dyeing bobbin can be freely contracted.

As described above, the thickness of the yarn is averaged over the entire yarn layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments.

FIG. 1 shows a staining bobbin 1 according to the present invention,
The bobbin is composed of two parallel vertical bone members 5, 5 and a leaf spring for bridging the vertical bone members 5, 5 so as to be elastically deformable in a direction of increasing or decreasing the mutual interval M between the vertical bone members 5, 5. Horizontal bone 3 ...
A large number of stains are applied to the vertically elongated elastically deformed fence wall 6 composed of
A plurality of holes 2 are arranged in parallel in the circumferential direction with a vertically long fixed wall portion 7 penetrating therethrough interposed therebetween .

Although the dyeing holes 2 are substantially square in the illustrated example, they may have various shapes such as a circle, a rectangle, and an ellipse.

Further, the staining holes 2 are vertically elongated fixed walls 7.
Are arranged one by one in each row, but may be arranged in a plurality of rows.

The spring-like horizontal bones 3 are U-shaped in the illustrated example, but any shape can be used as long as the space M between the vertical bone members 5, 5 can be increased or decreased by utilizing elasticity. May be.

For example, circular, elliptical, waveform, V-shaped, W
Shape and the like.

When the distance M is increased or decreased, the spring-like horizontal bone 3 is perpendicular to the two parallel vertical bone members 5 so that the vertical bone members 5 do not shift up and down. Bridged at the point.

Further, the dyeing bobbin of the present invention has
An outer cutout 14 and an inner cutout are provided at the upper and lower ends of the fixed wall 7.
Blade-shaped curved pieces 4 and 4 having a portion 15 are provided.
This curved piece 4 has other curved pieces 4 adjacent to each other.
And independent. In other words, the position between the vertical bone members 5, 5
Many slits 20 in the inclined direction when viewed from the axial direction
The blade-shaped curved pieces 4 are thus formed.
I have.

Then , the yarn is wound around the outer peripheral wall of the dyeing bobbin 1 configured as described above while leaving both ends slightly, and a cylindrical yarn layer 11 to be dyed is formed as shown in FIG. .

Then, the dyeing solution is discharged from the gap between the dyeing holes 2 of the dyeing bobbin 1 and the elongated elastically deformable fence walls 6 to dye the yarn layer 11 in a heated state.

In this case, as shown in FIGS. 3, 4, and 5, the spring-like transverse bones 3 are compressed in accordance with the contraction of the thread layer 11, and the circumferential surface of the dyeing bobbin 1 is moved in the radial direction. The vertically long fixed walls 7 shrink without shifting vertically.

More specifically, according to the tightening force of the yarn layer 11,
Are elastically deformed, and a plurality of the lateral ribs 3 are arranged in the circumferential direction.
The vertically long fixed walls 7 are moved in parallel with each other and come into contact with each other.
Get closer. At the same time, the upper and lower ends of the vertically long fixed wall 7 ...
The curved piece 4 attached to the outside is a cutout on the outer surface of one curved piece 4.
14 and the inner notch 15 of the adjacent curved piece 4 overlap each other.
The upper and lower edges 8 of the dyeing bobbin 1
9 reduced to substantially concentric. In other words, the overall shape is uniform
(Uniformly) Reduced diameter and uniform from upper edge 8 to lower edge 9
(The dyeing bobbin 1 is reduced uniformly in the radial direction.)
Do).

Accordingly, the yarn at the inner peripheral portion Q around the dyeing bobbin 1 can be freely contracted, similarly to the middle to outer peripheral portions P of the yarn layer 11, and the elasticity of the yarn is not lost.

The thickness of the yarn is averaged over the entire yarn layer 11,
Since the intervals between the yarns in the inner peripheral portion Q are also uniform, the dyeing liquid penetrates the entire yarn layer 11 on average, and the yarns do not have uneven dyeing.

Therefore, even if the dyeing bobbin 1 shrinks due to shrinkage of the yarn layer 11 during dyeing, the dyeing liquid does not leak, and uneven dyeing does not occur on the upper and lower surfaces 12, 13 of the yarn layer (see FIG. 5).

The shape of the curved pieces 4 is not limited to the above shape, and may be any shape as long as the curved pieces 4 can overlap each other when the dyeing bobbin 1 is reduced in diameter.

For example, the outer notch 14, the inner notch 1
Instead of 5 , a curved piece 4 having a substantially rhombic cross section obtained by diagonally cutting both diagonals of a sector may be used.

It is to be noted that the present invention is not limited to the embodiment shown in the drawings, and the design can be freely changed. For example, the vertically long fixed walls 7 in FIG. It is free to be configured in series. At this time, the curved pieces 4 are attached to the vertical bone members 5 at the upper and lower edges 8, 9 of the staining bobbin 1.

The material of the dyeing bobbin may be any material as long as it is elastic. For example, a synthetic resin is used.
