Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preparing a warped beam for a beam wet processing machine such as a beam dyeing machine.

More specifically, the present invention relates to a method for preparing a warped beam suitable for wet processing such as gluing, scouring, bleaching, and dyeing in a beam wet processing machine.

Conventionally, when weaving fabrics from threads such as cotton threads, it has been necessary to warp the warp threads, glue them using a slasher glue machine, and dry them.

That is, in preparing the warp for yarn-dyed fabrics, the yarn is wound around a large number of cheeses or cones, the cheeses or cones are package-dyed, and then glued. , the cone is placed in a partial warping machine to prepare a warping beam.

Alternatively, yarn dyed and glued from cheese or corn is wound up to form a plurality of beams using a rough warping machine, and the yarn is rewound from this rough winding beam to obtain the desired number of yarns. Prepare a warping beam.

In preparing the warp for piece-dyed fabrics, the yarn (preliminarily scoured and/or bleached if necessary) was wound up.

Set up a large number of cheeses or corn on a creel stand,
After warping the beam, the resulting warped beam is glued using a slasher glue machine, dried, and then wound back into a loom beam. was needed.

However, in the conventional method described above, the preparation process includes many operations, and the process of winding and unwinding the yarn is performed multiple times, which requires troublesome control such as adjusting the tension applied to the yarn. It is.

An object of the present invention is to prepare a warping beam suitable for subjecting yarn to gluing, scouring, bleaching, dyeing, and/or other wet treatments and drying treatments while wound onto the beam. The purpose is to provide a method.

Another object of the present invention is to provide a method for preparing a warped beam in a simple manner that does not cause inconveniences such as unwinding during processing steps.

Still another object of the present invention is to provide a method for preparing a warping beam without reducing the elongation of the yarn.

In the method of preparing a warping beam for a beam wet processing machine according to the present invention, a beam of a beam wet processing machine having a large number of through holes on the circumferential surface and flanges at both ends is coated with yarn from a large number of cheeses or corns. When winding the beam while applying a twill, one or more partition plates are provided on the beam, each having a length of 450 mm.
1nr/L or less, two or more winding sections are formed, and each winding section has a thickness of 7Qmm±5mrIL and a winding density of 0.
．． It is characterized by forming a wound layer of 3 to 0.4 g/crit.

Further, in the method of the present invention, a beam having a large number of needles implanted in the circumferential surface along with a large number of through holes can be used.

The method of the invention will now be described with reference to FIGS. 1 and 2 of the accompanying drawings.

The beam A used in the method of the present invention has a large number of through holes a on its circumferential surface, and a large number of needles are implanted on the circumferential surface of the beam A between these holes as desired. Good too.

This through hole a generally has a diameter of about 5 mm,
They are distributed on the beam circumferential surface at a density of about 1oooo pieces/m'.

Additionally, if a needle is provided, it generally has a diameter of approximately 1 mtr.
t and a length of about 2, are implanted at a density of about 10,000 pieces/rrr'' on the circumferential surface of the beam.

These needles are effective in preventing the wound layer from collapsing.

The beam A is provided with one or more partition plates C, and both ends of the beam A are provided with flanges.

By providing one or more partition plates C between the flanges, two or more winding sections each having a length of 450 mm or less are formed on the circumferential surface of the beam A.

For example, if the length B between the flanges is 1800 mm and three partition plates C are provided at equal intervals, four winding sections each having a length of about 450 mm are formed.

There is no particular limitation on the diameter of the beam, but generally, a diameter of about 620 mm is in practical use.

A desired number of yarns are wound from cheese or corn onto each winding section of the beam formed as described above, while being traversed.

At this time, it is necessary to adjust the thread tension and winding speed to adjust the winding density of the thread-wound layer to 03 to 04 g/Cll1, and to set the thickness of the thread-wound layer to 70±511 tN. It is.

The length of the winding section is 450i11! When it gets bigger,
During drying, the thread layer collapses, which tends to cause dry spots on the top and bottom of the beam.

If the thickness of the thread layer in each winding section is greater than 75 mm, the passage resistance of the processing liquid will increase, resulting in non-uniform processing in each processing step.
If it is smaller than a mountain, the production amount per batch is small, resulting in inefficiency.

Furthermore, if the winding density of the thread-wound layer is less than 0.3 g/-, cracks or cracks will occur in the beam, resulting in leakage of processing liquid or hot air, resulting in uneven processing. If it is larger than /-, the passage resistance of the processing liquid and the like becomes large, resulting in problems such as processing unevenness due to a decrease in flow rate and a low elongation of the product.

In FIG. 2, winder 1 is a known variable speed electric winder whose winding speed and tension can be automatically adjusted by means of a known feedback system (not shown). .

A large number of cheeses 3 are set on a creel stand (not shown), and a large number of threads Y are pulled out from the cheeses 3. Each thread Y is adjusted to a desired tension by a vertically movable tension control device 3. It is prepared, warped in parallel to each other by a reed 4, taken up by a pair of press rolls 5, and wound into a beam A.

At this time, a traverse motion is applied to the reed 4 and the press roll, and the yarn Y is cradled.

Although there is no particular limitation on the type of yarn to which the method of the present invention is applied,
In particular, it is preferable to use cotton thread.

The method of the present invention has the following features.

1. The obtained warping beam can be directly subjected to yarn scouring, bleaching, dyeing, gluing, and other wet processing and drying processes, without requiring an unwinding process between these processes. do not.

2. There is no need to use a conventional slasher glue machine,
Therefore, there is no need to dry the glued yarn in a cylinder, and there is no decrease in the elongation of the yarn.

3. Therefore, since there is little variation in the elongation of the obtained yarn, it is possible to rewind it at high speed without any variation in tension.

4. The strength and elongation of the obtained yarn is good.

5. Compared to cheese, there is no risk of air leakage due to spacers, etc. During drying, air flows effectively through the thread-wound layer, resulting in uniform processing and shortening the time required for drying.

6. Since the yarn obtained has uniform elongation and tension, the texture of the fabric obtained using this yarn is good.

7. There are fewer thread breaks during weaving, improving the operating efficiency of the loom.

8. Equipment costs, personnel costs and operating costs can be saved.

The method of the invention will be further illustrated by examples.

Example 1 The following method and beam with interception were used.

30 cotton yarns and 500 twin yarns were wound around each winding section of the beam.

The density of the obtained thread-wound layer was 0.36 g/i, and the strength was 70.

The four warped beams obtained as described above were connected in series and loaded into a beam dyeing machine, dyed and pasted in a conventional manner, and dried in a hot air dryer in a conventional manner.

No deformation or uneven drying was observed in the wound layer of the warp beam obtained.

A desired loom beam was warped from the dyed, glued, and dried diameter-sized beam using a partial warping machine.

When a yarn-dyed fabric was woven from the loom beam thus obtained, neither uneven dyeing nor uneven adhesion was observed in the obtained fabric.

However, the yarn used was 20S cotton yarn, 50 yarns per winding section.
There were 0 pieces.

The thread-wound layer had a winding density of 0.35 jj /crrt and a thickness of 75 mm.

This warped beam was subjected to conventional scouring and gluing treatments using a beam dyeing machine similar to that used in Example ①, and then hot air drying was performed in a conventional manner.

No deformation was observed in the thread-wound layer in each winding section, and it was uniformly dried.

A loom beam was warped from the warp beam in the same manner as in Example 1, and a woven fabric was woven from the warp beam.

Neither scouring unevenness nor gluing unevenness was observed in the obtained fabric.

Example 3 The same operation as in Example 1 was performed.

(tab, a needleless beam was used.

Good results similar to those of Example 1 were obtained.
