Description

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

More specifically, it relates to a yarn processing method that uses a warping beam to sequentially perform desired wet treatments such as scouring, bleaching, dyeing, gluing, and oiling, and then drying the yarn. It is. Conventionally, when weaving fabrics from threads such as cotton threads, it has been necessary to warp the warp threads, apply glue to them using a scraper gluer, 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 glued thereto, and the cheese or cones are package-dyed. The cone was attached to a 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 form the desired shape. A warping beam with a certain number of threads was being prepared. 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, various steps are required such as gluing the warped beam using a slatsher gluing machine, drying it, and winding it back into a beam for a loom. Met. 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 wind yarn into the shape of a warping beam, sequentially subjecting it to desired wet treatments such as scouring, bleaching, dyeing, and gluing, and drying it. An object of the present invention is to provide a method for processing yarn using the method.
A yarn processing method using a warping beam according to the present invention is a yarn processing method using a warping beam having a number of through holes on the dark side and flanges at both ends.
One or more partition plates are provided on the beams for the wet processing machine to form two or more winding sections each having a length of 450 skins or less, and for each winding section, a large number of cheeses, Alternatively, wind a number of threads from the cone while applying criss-crossing to form a thread layer with a thickness of 7 x 15 sides and a winding density of 0.3 to 0.4 x 1/2, and apply the warp to the resulting warp beam. This method is characterized in that a desired wet treatment is performed in a beam wet treatment machine, and then a dry treatment is performed thereon.

The beam used in the method of the present invention may have a number of through holes and a number of needles implanted on its peripheral surface.

The method of the present invention will be explained with reference to FIGS. 1 and 2.

The warping beam used in the method of the present invention is formed using, for example, a beam for a beam wet processing machine as shown in FIG. In FIG. 1, the beam A has a large number of through holes a on its circumferential surface, and a large number of needles b may be provided as shields on the cylindrical surface of the beam A between these through holes. good.

The through holes a generally have a diameter of about 5 ribs, and are distributed around the beam circumferential surface at a density of about 1000 solid holes.
Further, the needles b generally have a diameter of about one rib and a length of about two skins, and are distributed around the beam circumferential surface at a density of about 10,000 pieces/me. 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 45 mm or less are formed on the circumferential surface of the beam A. for example,
When the length B between the flanges is 180 ribs and three partition plates C are provided at equal intervals, four winding sections each having a length of about 450 ribs are formed. Although there is no particular limit to the diameter D of the beam, a diameter of about 62 mm is generally used. Traverse the desired number of yarn warps from cheese or corn to each winding section of the beam formed as above.
Wind it up while applying. At this time, the tension of the yarn and the winding speed are adjusted so that the winding density of the thread layer to be formed is 0.3.
The thickness of the thread layer was adjusted to ~0.4 ta', and the thickness of the thread layer was 70 min.
It is necessary to make the skin. If the length of the winding section is greater than 45 mm, the thread layer may collapse during drying, resulting in dry spots on the top and bottom of the beam.

When the thickness of the thread layer in each winding section is greater than 75 ribs,
Since the passage resistance of the treatment liquid becomes large, there is a disadvantage that the treatment becomes non-uniform in each treatment step, and when the length is 4 mm smaller than 65, there is a disadvantage that the amount of production at one time is small and inefficiency is caused. Furthermore, if the winding density of the thread layer is lower than 0.3 mm/ground and 4 mm, cracks or cracks will occur in the beam, resulting in leakage of treatment liquid or hot air, resulting in uneven treatment, and , 0.4 mm/ground, the passage resistance of the treatment liquid and the like becomes large, resulting in the drawback that uneven treatment and elongation are reduced due to a decrease in the flow rate. 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 control system (not shown).

A large number of cheeses 3 are installed on the IJ-le stand (not shown), and from this cheese 3 a large number of threads Y.
is pulled out, each yarn Y is adjusted to a desired tension by a vertically movable tension control device 3, warped parallel to each other by a reed 4, taken up by a pair of press rolls 5, and wound around a beam A. taken.

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, it is particularly preferable to use cotton yarn.

One or more warping beams formed as described above are
It is loaded into a beam green processing machine, such as a beam dyeing machine, where it is sequentially subjected to the desired overflow processing, such as scouring, bleaching, dyeing, gluing, and other wet processing. There is no need to rewind the yarn between each processing step. When the desired green treatment is completed, the yarn is subjected to a drying treatment while still in the warp beam state. There are no particular limitations on the type of wet treatment, treatment conditions, etc. Further, there are no particular limitations on the method and conditions for the drying process, but generally a hot air circulation drying method is used in which hot air is circulated through a thread-wound layer on a beam. The method of the present invention has the following features.

1. Since the warping beam can be directly subjected to yarn refining, bleaching, dyeing, gluing, and other wet processing and drying processes, no unwinding process is required between these processes.

2 There is no need to use a conventional slasher gluing 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 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 Compared to cheese, air I due to Subaser etc.
During drying, air flows effectively through the wound layer as there is no risk of J-ke, which results in a more uniform process and shorter drying times.

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. Labor costs and operating costs can be saved. The method of the present invention will be further explained by examples.

78 Hiho number 3
pieces (winding section length approx. 45 mm) Through hole diameter 5th side density
1000 hard/fixed needle diameter
1 Rib Length 2 Rib Density 1000q / 500 3-ply cotton threads were wound around each winding section of the above beam.

The resulting wound layer had a density of 0.36 mm and a thickness of 7 mm. The four warped beams obtained as described above were connected in series and loaded into a beam dyeing machine, dyed and glued using the usual method, and dried at 10yo using a hot air dryer using the usual method. Dry.

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, pasted and dried warped beam using a partial warping machine.

When a yarn-dyed fabric was woven from the loom beam thus obtained, neither uneven dyeing nor uneven gluing was observed in the obtained fabric. Example 2 The same operation as in Example 1 was performed.

However, the needle is not shielded on the peripheral surface of the beam, and
The yarn used was 2-go cotton yarn, 500 yarns per winding section. In addition, the winding density of the thread-wound layer is 0.35 m/s, and the thickness is 7
It had 5 ribs. This warped beam was subjected to conventional scouring and gluing treatment using the same beam dyeing machine as in Example 1, and was then subjected to hot air drying at 10,500 liters for 60 minutes 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.
