Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn processing method using a warping beam.

More specifically, the present invention provides a yarn processing method in which the yarn is subjected to scouring, bleaching, dyeing, gluing, oiling, and other wet treatments using a warping beam, and then subjected to drying treatment. It is related to. Conventionally, cheese processing and warp beam processing have been used to form loom beams from raw yarn.

In the cheese processing method, raw yarn (e.g. spun cotton yarn) is wound into a cheese shape on a perforated dyeing tube (bobbin), the cheese is mounted on a carrier of a processing device, and subjected to the desired wet treatment, e.g. The method used is to scouring, bleaching, dyeing, gluing or oiling, drying, rewinding, and winding it into a beam with a warper to make a loom beam.

This method requires a lot of manpower and time due to the large number of processed cheeses, and also requires steps such as rewinding and beam winding using a warper, which is unsatisfactory from the viewpoint of labor and energy saving. There is a problem that unevenness tends to occur. In addition, in the conventional warp beam processing method, the raw cheese is placed on the creel stand of the Aramaki warping machine and beam warped, and then scouring, bleaching,
After the desired dyeing process is applied, the warp beam is dehydrated, the yarn is pulled out of the beam, subjected to slatsher sizing, dried, and then returned to the loom beam. ing.

In this method, the gluing step and the drying step are carried out using a slatsher, which tends to cause drawbacks such as reduced yarn elongation and non-uniform gluing. Another disadvantage is that a slasher gluing machine is required in addition to the beam processing machine. The object of the present invention is to sequentially perform various wet treatments such as scouring, bleaching, dyeing, gluing, oiling, etc. on the yarn in the state of a warping beam, and then drying the yarn. It is an object of the present invention to provide a yarn processing method using a straightening beam that can prevent a decrease in the elongation of the yarn and the occurrence of uneven processing.

The yarn processing method using the warping beam of the present invention involves winding a large number of yarns on the circumferential surface of the beam, subjecting the obtained warping beam to a desired wet treatment in a beam wet treatment machine, and then When drying the beam, the radius D of the beam and the thickness d of the thread-wound layer on the circumferential surface of the beam are determined by the following relational expression:

・3≦word plow 5 is satisfied, and the thickness d of the thread-wound layer is 120
It is characterized by being below the ribs.

In a conventional yarn processing method using a warp beam, a warp beam is formed by winding a large number of yarns onto the circumferential surface of a beam having a large number of through holes on the circumferential surface.

At this time, the winding density of the thread-wound layer on the warp beam is generally 0.
The thickness was greater than 4 mm and less than 0.45 mm, and the thickness of the thread layer was 125 to 150 mm. In the wound layer of such a conventional warp beam, the radius of the beam is D
When the thickness of the thread-wound layer is expressed as d, the ratio d/D is:
It was greater than 0.5, usually greater than 0.6. The wound layer of such a conventional warp beam has a relatively large resistance to the passage of processing liquid and hot air, which may cause the shape of the wound layer to be distorted or the effects of dyeing, gluing, drying, etc. to be uneven. Therefore, the quality of the yarn obtained was also unsatisfactory. In the method of the present invention, the following relationship is satisfied in the wound layer in the warping beam:
.

・3≦effect≦. -5 and the thickness of the pincushion layer is regulated to 120 ribs or less.

At this time, the winding density of the thread-wound layer is preferably within the range of 0.3 to 0.4 m/m, more preferably 0.32 to 0.4 m/m. More preferably, it is within the milk/lump range. A wound layer that satisfies the above requirements can be uniformly subjected to wet processing and drying treatment, and the wound layer does not lose its shape.

When the wound layer does not meet the above requirements, wet processing and drying may become uneven, the wound layer may become deformed, and the elongation of the yarn may decrease. There are no particular restrictions on the type of gutter treatment, treatment conditions, etc. in the method of the present invention, and ordinary scouring, bleaching, dyeing, gluing, oiling, etc. can be sequentially performed using an ordinary beam processing machine.

In the method of the present invention, the yarn that has been subjected to the desired treatment is dried in the state of a warping beam, but there are no particular limitations on the type of drying treatment or treatment conditions, and ordinary dehydration and drying method can be applied.

However, in general, a method of dehydrating and drying is used by circulating air, preferably a heat sink, through the thread-wound layer.
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 In the method of the present invention, the warping beam can be directly subjected to yarn scouring, bleaching, dyeing, gluing, and other wet processing and drying processes, and there is no need for a rewinding process behind these processes. .

2 There is no need to use a conventional slasher gluing machine,
Therefore, there is no need to perform cylinder drying on the pasted yarn, and no decrease in elongation of the yarn occurs.

3. Therefore, since the elongation of the obtained yarn fluctuates slightly, it is possible to rewind it at high speed without fluctuations in tension.

4 In addition, the strength and elongation of the obtained yarn is good.

5 The winding density of the threaded layer is uniform and there is no air leakage as can be caused by the use of swathers in cheese processing, so that air flows effectively through the threaded layer during the drying process, which improves the process. Drying is done uniformly and the time required for drying is shortened.

6 The texture of the resulting fabric is good because the elongation and tension of the resulting yarn are uniform.

7. Fewer thread breakages during weaving (improves loom operating efficiency).

8. Equipment costs, personnel costs and operating costs can be saved. Example 1 50 staples of 3-ply double cotton yarn were wound around a porous warping beam having a radius of the first notation to form a wound layer having a thickness of the first notation.

At this time, the density of the thread-wound layer was about 0.36 m/clump. Each thread-wound layer was sequentially subjected to dyeing, gluing, and drying operations using conventional methods. The results are shown in Table 1. Table 1 Example 2 500 3-ply cotton twin yarns were wound around a warping beam with a radius of 265 mm to form a wound layer having the density shown in Table 2 and a thickness of 12 mm.

This thread-wound layer was subjected to dyeing, gluing, and drying treatments using conventional methods.
