する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to improvements in covered elastic yarns made by winding polyamide-based synthetic fiber multifilament crimped yarns around elastic yarns such as polyurethane yarns, particularly for pantyhose, The present invention relates to a single-ply elastic yarn that has excellent durability and high-speed knitting properties as a material for a part of panties, and has excellent productivity during covering.

バード糸と呼ばれている。(Prior Art) Pantyhose are widely used by knitting covered elastic yarns in which polyamide-based synthetic fiber multifilament yarns are wound around elastic yarns such as polyurethane yarns. The covered elastic yarn is produced by a covering machine shown in FIG. 1 and is called a covered yarn.

，５倍に伸長し、ポリアミド系合成繊維板撚加工糸３０

重被覆したカバード糸を使用している。In general, the covered yarn for pantyhose and haunches is 3x to 3x spandex 20~50d.
, 5 times elongated, polyamide synthetic fiberboard twisted thread 30
A covered yarn having a single covering of d to 50 d with a covering number of 700 to 1000 t/m is used.
このカバリング法においては中空スピンドルの回転数の
機械的制約のため加工速度が低くなり、従って生産性が
低く高価なものになる。In this covering method, the processing speed is low due to mechanical constraints on the rotational speed of the hollow spindle, resulting in low productivity and high costs.

昭５１−１１２９５６号公報等で伸長した弾性糸と熱可
塑性合成繊維を引きそろえ仮撚加工により弾性糸を芯糸

れているが、仮撚熱固定により弾性糸の伸長回復性が低
下する。As a method for improving this, JP-A No. 47-35341 and JP-A-51-112956 disclose that elongated elastic threads and thermoplastic synthetic fibers are aligned, the elastic threads are cored through a false twisting process, and thermoplastic synthetic fibers are made. Although a coated elastic yarn using a sheath yarn as a sheath yarn has been disclosed, the elongation recovery property of the elastic yarn decreases due to false twist heat setting.

が、流体処理と加熱の２工程が必要であり、設備が煩雑
であり、かつ−而の均−感に欠けるものである。On the other hand, Japanese Patent Application Laid-Open No. 62-69845 discloses a method in which a crimped yarn of inelastic fibers and an elongated elastic yarn are simultaneously treated with a fluid and then heated at 50 t/m or more to obtain a bulky elastic yarn. Two steps, treatment and heating, are required, the equipment is complicated, and the process lacks uniformity.

低下させても被覆性を維持させることが示されている。In order to improve productivity even with the ordinary covering method, in JP-A-61-102442, the cross-sectional shape of the wound yarn is made non-circular to improve the covering property and maintain the covering property even if the number of coverings is reduced. It has been shown that

では生産性が良いとは言いがたい。In JP-A-61-102442, the number of coverings is clearly disclosed. In the examples, 20 denier spandex is stretched 3.2 times with double-covered elastic yarn, 15 denier, 5 filament, 12 denier. The covering number for winding 5-filament nylon 6-filament yarn is only indicated as 2,800 t/m for the first twist and 2,400 t/m for J twist, and it cannot be said that productivity is good with this twist coefficient. sea bream.

The purpose of the present invention is to provide an E1 elastic yarn.

The yarn is made of a single-covered elastic yarn characterized in that the covering number T (t/m) satisfies formula (1).

Elastic fibers of this type are preferred, but other types of elastic fibers may also be used.
ポリアミド系合成繊維マルチフィラメント捲縮加工糸は
ナイロン６、ナイロン６６などの通常の仮撚加工糸が好
ましい。The polyamide synthetic fiber multifilament crimped yarn is preferably a normal false twisted yarn such as nylon 6 or nylon 66.
特に、パンティ一部で交編される仮撚加工糸を捲付糸と
して使用することがより好ましい。In particular, it is more preferable to use a false twisted yarn that is inter-knitted in a portion of the panty as the wrapping yarn.

ング数が前記（１）式を満足させるこフィラメント捲縮
加工糸のデニールとフィラメント数及びカバリング数を
種々検討の結果、本発明に至った。In order to obtain a single coated elastic yarn with excellent uniformity of the knitting surface of a part of the panty and productivity during covering, the present invention aims to satisfy the above-mentioned formula (1) with the number of coverings and the denier of the filament crimped yarn. As a result of various studies on the number of filaments and the number of coverings, the present invention was arrived at.
（１）式よりカバリング数を大きくすればカバリング機
の中空スピンドル回転数の機械的制約のためカバリング
速度が低くなり生産性が落ちる。According to equation (1), if the number of coverings is increased, the covering speed will be lowered due to the mechanical restriction of the rotational speed of the hollow spindle of the covering machine, resulting in a decrease in productivity.
また、ヤーン集束性は向上するが、バルキー度に欠け、

感に欠ける。In addition, although yarn convergence is improved, bulkiness is lacking,
- When part of the panty is knitted by inter-knitting heavy-covered monoelastic yarn and polyamide-based synthetic fiber multifilament crimped yarn, the course knitted with single-covered elastic yarn appears uneven and uneven -
It lacks a sense of feeling.
（１）式よりカバリング数が小さいとカバリング速度は
はやく生産性は向上するが、編立時の張力変動が大きく
編立糸切れが増加しゃすく編立性が悪い。According to formula (1), when the number of coverings is small, the covering speed is faster and the productivity is improved, but the tension fluctuation during knitting is large, the number of knitting yarn breakages increases, and the knitting performance is poor.

ため編立性が低下する。It is preferable that the covering direction is the same as the torque direction of the polyamide synthetic fiber K (4 multifilament crimped yarn) for threading. Single-covered elastic yarn covered in the opposite direction will have a stronger torque and will become loose during knitting. Knitting performance deteriorates due to snarling.

In the figure, spandex fiber Y is unwound from a package A by an unwinding roller 1, and is unrolled into a hollow by a supply roller 2. It is fed through a spindle 3 to a take-off roller 4. On the other hand, the polyamide synthetic fiber crimped yarn is unwound from the rotating hollow package B and wound around the spandex fiber Y1,
- A heavily covered elastic yarn Y is obtained. 5 is a guide, 6 is a winding roller, and 7 is a winding package.
