カバード糸と呼ばれている。(Prior Art) It has been widely practiced to knit a coated elastic yarn obtained by winding a polyamide-based synthetic fiber multifilament yarn around an elastic yarn such as a polyurethane yarn to form a pantyhose. The coated elastic yarn is made by a covering machine shown in FIG. 1 and is called a covered yarn.

に伸長し、ポリアミド系合成繊維仮撚加工糸30d〜50dを
カバリング数700〜1000t/mで一重被覆したカバード糸を
使用している。Generally, as a covered yarn for panty stockings and panties, spandex 20 to 50d is stretched 3 to 3.5 times, and a polyamide synthetic fiber false twisted yarn 30d to 50d is single-coated with a covering number of 700 to 1000 t / m. Uses covered yarn.

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 machining speed is reduced due to the mechanical restriction of the number of revolutions of the hollow spindle, so that the productivity is low and the cost is high.

JP-A-1112956 discloses a coated elastic yarn in which a stretched elastic yarn and a thermoplastic synthetic fiber are aligned, a false twisting process is performed, and the elastic yarn is used as a core yarn, and a thermoplastic synthetic fiber is used as a sheath yarn.
False twist heat setting reduces the elongation recovery of the elastic yarn.

かつ編面の均一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 an inelastic fiber and an elongated elastic yarn are twisted at least 50 t / m after simultaneous fluid treatment to obtain a wound bulky elastic yarn. Two processes of fluid treatment and twisting are required, the equipment is complicated,
In addition, the knitted surface lacks uniformity.

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 the productivity even in the normal covering method, Japanese Patent Application Laid-Open No. 61-102442 discloses that the covering shape is improved by making the cross-sectional shape of the wound yarn non-circular, and the covering property is maintained even when the covering number is reduced. It is shown to do.

すぎず、この撚係数では生産性が良いとは言いがたい。Japanese Patent Application Laid-Open No. 61-102442 does not clearly disclose the covering number. In Examples, 15 denier-5 filaments and 12 denier-5 filaments were obtained by stretching a 20-denier spandex 3.2 times with a double-coated elastic yarn. The number of coverings for winding the nylon 6 filament yarn is only 2800 t / m for the lower twist and 2400 t / m for the upper twist, and it is hard to say that the productivity is good with this twist coefficient.

しい。The polyamide-based synthetic fiber multifilament crimped yarn is preferably subjected to ordinary false twisting such as nylon 6, nylon 66, or the like.
特に、パンティー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 knitted and knitted in a panty portion as a wound yarn.

被覆糸のデニールとカバリング数の関係について鋭意検
討の結果、カバリングの生産性、編地の均一性、編立性
に優れた範囲についての関係をはじめて見出した。Generally, the twist coefficient W is Can be obtained by For the present invention, the elastic fibers D 1 as the core yarn when covering is extended, is covering the polyamide synthetic fiber multifilament yarns D 2 as a yarn dipped Maki simultaneously constant length condition. Therefore, the actual denier of the core yarn at the time of covering is corrected by the elongation. That is, D 1 / DF. Therefore, in determining the true twist coefficient, D is determined from real denier (D 1 / DF) + D 2 of the core yarn. Therefore, the equivalent yarn diameter during covering is And the twist coefficient is Is required. In this case, the filament number F of the polyamide-based synthetic fiber multifilament yarn of the covering wound yarn is used.
However, there is no disclosure of the relationship between the number of filaments and the number of coverings due to cross-sectional deformation due to false twist and due to the degree of convergence of multifilaments. The present inventors have proposed a filament number F, a core yarn,
As a result of intensive studies on the relationship between the denier of the covered yarn and the number of coverings, a relationship was found for the first time with respect to the covering productivity, the uniformity of the knitted fabric, and the range excellent in knitting.
（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姓が落ちる。If the number of coverings is increased from the equation (1), the covering speed is reduced due to the mechanical limitation of the number of revolutions of the hollow spindle of the covering machine, and the production name is reduced.

け、一重被覆弾性糸とポリアミド系合成繊維マルチフイ
ラメント捲縮加工糸を交編しパンティー部を編成すると
一重被覆弾性糸が編込まれたコースがスケ、段状に見え
均一感に欠ける。In addition, although the yarn bunching property is improved, the bulkiness is lacking, and when the single-coated elastic yarn and the polyamide-based synthetic fiber multifilament crimped yarn are knitted and knitted to form a panty portion, a course in which the single-coated elastic yarn is woven is Invisibility, stepped appearance, lacks uniformity.
（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やすく編立性が悪い。When the number of coverings is smaller than the formula (1), the covering speed becomes faster and the productivity is improved, but the tension fluctuation at the time of knitting is large and the breakage of the knitting yarn tends to increase, resulting in poor knitting.
又、被覆性が低下するため、縫製で編地切断ケ所での
弾性糸が抜けやすい。In addition, since the coatability is reduced, the elastic yarn is easily pulled out at the knitted fabric cutting point by sewing.
カバリング方向は捲付用ポリアミド系合成繊維マルチ
フイラメント捲縮加工糸のトルク方向と同一とすること
が好ましい。逆方向でカバリングした一重被覆弾性糸は
トルクが強くなり、編立時ビリ立ち、スナーリングのた
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 crimped yarn of the polyamide synthetic fiber multifilament for winding. The single-coated elastic yarn covered in the reverse direction has a high torque, and is stiff when knitting, and the knitting property is reduced due to the snorling.

良好である。When the single-coated elastic yarn of the present invention is wound into cheese, a cheese with a belly hardness of 70 ° or more and a belly hardness equal to or higher than the edge hardness of 5 ° has a good cheese unwinding property. .

In FIG. 1, a spandex fiber Y 1 is unwound from a package A by an unwinding roller 1 and is supplied by a supply roller 2. It is fed to a take-up roller 4 through a hollow spindle 3. On the other hand, polyamide synthetic fiber crimped yarn Y 2 from the hollow package B to rotate the attached Maki around the spandex fiber Y 1 being unwound, singlet covered elastic yarn Y 3 is obtained. Reference numeral 5 denotes a guide, 6 denotes a winding roller, and 7 denotes a winding package.
