優れたWJLの製織方法に関するものである。More specifically, it relates to a WJL weaving method that provides excellent weavability and fabric quality when weaving using spun yarns made of polyester fibers, particularly polyester fibers spun at a speed of 6000 m/min or more, as weft yarns.

ている。Spun yarn fabrics made of polyester fibers spun at a winding speed of 6,000 m/min or more have volume, a soft texture, low heat shrinkage, high dimensional stability, and wrinkle resistance. We can provide fabrics that have the advantage of being difficult to form. In addition, it has the excellent characteristic of being easy to dye, and has the advantage of not impairing the properties of other materials in mixed-woven fabrics.

として非常に有効なものである。Shuttle looms, rapier looms, air jet looms, and WJLs are used as weaving means that use the spun yarn as weft yarns. In particular, WJLs are capable of high-speed weaving and can be installed in large numbers, so they reduce weaving costs. It is very effective as a means of reduction.

だ充分な解決策が見い出されていなかった。[Problems to be Solved by the Invention] However, the weavability of WJL using this spun yarn as the weft has a lot of fuzz and yarn defects like conventional spun yarns, making it difficult to achieve stable weft insertion. This resulted in a large number of loom stops, resulting in a significant drop in loom operating efficiency. Therefore, there was a problem in that, despite the increased speed, it was not possible to obtain a sufficient improvement in productivity. Furthermore, in terms of fabric quality, in addition to defects such as stopper steps, there is also a problem in that weft sink marks and through-through defects are likely to occur. There are measures such as increasing the number of spinning fuels to eliminate this weft sink and slippage, but this is undesirable because it reduces the volume and softness, which are the characteristics of the texture of the fabric. Even with weaving technology measures such as making the yarn grip softer, the problem could not be resolved, and a sufficient solution had not yet been found.

When weaving with WJL using a spun yarn composed of polyester fibers spun at a speed of 000 m/min or more for the weft,
The object of the present invention is to provide a weaving method that solves the above-mentioned problems and has excellent weavability and fabric quality.

出した。即ち、この高い張力が付加されることによって
、満足な緯糸挿入を得ることが出来ず、織機停台の増加
、緯ヒケ欠点等の発生を助長している訳である。The inventors of the present invention have conducted various studies on stable weft insertion measures and solutions for fabric defects such as weft sink and shedding, and as a result, the weft yarns are unwound from the length measurement storage device and included in the water jet jetted from the nozzle. However, at this time, in addition to the poor unwinding properties due to the fluff that is unique to spun yarn, the high tension that is applied during flight affects flight performance. We found that this is a major factor contributing to instability. That is, by applying this high tension, it is not possible to obtain a satisfactory weft insertion, which promotes an increase in the number of loom stops and the occurrence of weft sink defects.

This will be explained using figures. FIG. 3 shows an example of the tension transition of a weft thread during flight using a length measuring and storage device for the second drum. This tension was continuously detected by installing a known tension detector (8) in front of the injection nozzle (11) on the weft yarn (9) unwound from the measurement storage device as shown in Figure 4. It is something.

〜20倍の高い飛走張力が急激に加わる。In FIG. 3, the weft yarn starts flying at a loom crank angle θ1 and ends at a loom crank angle θ3. Incidentally, θ4 is the crank angle at the time of beating the reed. Here, the drum-type length measuring and storing device has a mechanism that measures the length of the next weft insertion at a constant rotation speed and simultaneously winds and stores the length, so that even when the weft insertion is finished, the length of the next weft insertion is continuously measured. We have started storing the inserted amount. However, the entire weft length for one weft insertion is not wound on the drum and stored in advance, but only a part of the weft length required for one weft insertion is wound and stored on the drum in advance. . The remaining short length is fed by the measuring roller and is simultaneously flown. In FIG. 3, the crank angle between θ1 and θ2 is newly stored before the start of flight and during flight. Therefore, this part is a flying area where the unwinding tension is low, where the weft yarn flies depending on the speed of the jetted water flow, and is a so-called "free flying area." On the other hand, between the crank angles θ2 and θ3, the weft yarn is fed by the length measuring roller and simultaneously runs in the portion corresponding to the shortened length. This part is called the "restricted flight area", and at θ2 at the start of this restricted flight, the flight tension is 5
~20 times higher flight tension is suddenly applied.

。In other words, it is as if a sudden brake is applied to the weft yarn flying. The application of such high tension strongly stretches the spinning system, promotes the occurrence of weft sink defects, and is a major factor contributing to unstable flight performance.

Further, copolymers with small amounts of other components may also be used within a range that does not impair the purpose of the present invention.

る以前に、ドラム貯留部に貯留する機構を持つ緯糸測長
貯留装置を設置することによって達威される。In the present invention, the completely free flying system means that the weft yarn flies with a relatively constant low tension from the time it starts flying until it ends. An example of tension transition is shown. During the period from θ1 when flying starts to θ3 when the weft gripper closes and ends flying, the weft thread always flies with a constant low tension without any particularly high tension being applied. This can be achieved by installing in advance a weft length measuring and storage device having a mechanism for storing weft yarns with a weft insertion length of 1 or more in the drum storage section before the weft yarns start flying.
この測長貯留装置はドラム貯留部から解舒される1越分

解舒時、即ち、緯糸飛走時に過分な張力がかからなくす
るために、ドラム上で隣接系が接触、重り合わない様に
セパレートに巻き取る方式が好ましい。This length measuring storage device has a mechanism for regulating the length of one weft yarn unwound from the drum storage section using a photoelectric sensor or the like. In addition, this drum storage section stores 1 to 2 excess weft yarns, and
In order to prevent excessive tension from being applied during unwinding, that is, when the weft yarns fly, it is preferable to wind the yarns separately so that adjacent systems do not come into contact with each other or overlap each other on the drum.

で全自由飛走を採ることも一部改造で機構的に可能であ
るが、パイプ内に紡績糸の風綿による糸づまりが発生し
て、バイブ内からの解舒性が悪くなることがあり、前記
ドラム貯留方式を採用することが好ましい。Other weft length measurement and storage methods include an in-pipe storage method using air suction or air injection. Although it is mechanically possible to achieve completely free flying using this method with some modification, the yarn may become clogged with the fluff of the spun yarn inside the pipe, making it difficult to unwind from inside the vibrator. It is preferable to adopt the drum storage method.
織機回転数としては300〜600rpmの間で製織す
るのが適している。300rpm以下では織物の生産性
が低く、6 0 0 rpm以上では緯糸の飛走性が悪
くなる傾向となる。It is suitable to weave at a loom rotation speed of 300 to 600 rpm. If the speed is below 300 rpm, the productivity of the woven fabric will be low, and if the speed is above 600 rpm, the flying properties of the weft yarns will tend to deteriorate.

構成された紡績糸は全自由飛走方式で行った。Example 1.2 and Comparative Example 1 Polyethylene terephthalate was wound up at 6000 m/min and 8000 m/min using the apparatus shown in FIG.
Yarns of 75d/36f were obtained respectively. Based on the obtained yarn, a stable of unequal length fibers of about 2 d and 76 to 102 M was manufactured. These stables were separately worsted-spun using a conventional method to obtain spun yarns each having a count of 48 twin yarns. Using these two types of spun yarn, the warp density is 55/inch and the weft density is 4.
Weaving was carried out using a WJL with a loom rotation speed of 400 rpm using a 5/inch flat structure. At this time, the spinning winding speed was 6000 m.
The spun yarn constructed with yarns of 1/2 minutes has two types of weft flying methods: the conventional combined method of free flying and restrained flying, and the completely free flying method, and the spinning winding speed is 8000 m. The spun yarn composed of yarns of /min was made using a completely free running method.

It is also possible to eliminate weft sink marks and imperfections. Table 1 [Effects of the Invention] By using the weaving method of the present invention, it is possible to obtain a woven fabric that has a high wt machine operating rate, has few fabric defects, and has an excellent texture.
