られてきた。Conventional technology In general, textile materials used for women's socks, etc. are required to have moderate stretchability, high transparency, and uniform dyeing, and furthermore, the economic efficiency of high-speed production of these textile materials is required. Usually, a core yarn made of elastic yarn such as polyurethane is wrapped with thermoplastic synthetic fiber filament yarn such as polyamide as a covering yarn, and in this case, the covering yarn is untwisted or has a slight twist of 20 T/m or less. So-called flant yarns (drawn yarns that are not subjected to various types of first twisting) have been used.

覆糸を巻付けてなる被覆弾性糸において。Means for Solving the Problems A covered elastic yarn is provided in which a covered yarn made of thermoplastic synthetic fiber is wound around a core yarn made of elastic fiber.

とするものである。The fineness of the core yarn of the elastic yarn is 10D or more and 40D or less (hereinafter referred to as denier), and the covering yarn covering this core yarn is an ultra-fine fineness yarn of 5D to 15D.
1580 force D T/m or more 15800/, /fi T/
It is characterized by using a strong-twist machine-heat-sensed yarn 1~ that has a torque of 8 T/m or more and 200 T/m or less after being imparted with a strong twist of not more than m or more and immediately subjected to dry heat treatment to stop the twist. It is something.

て、この撚のため乱反射し。A core yarn made of elastic fibers with an action of 10D to 40D,
The coated elastic yarn is made by applying a predetermined strong twist to the ultra-fine fineness yarn of D, and then winding the coated yarn in a spiral shape after dry heat setting and fixing the twist.The appearance of the coated elastic yarn is that the coated yarn is highly twisted. This twist causes diffuse reflection.

、被覆糸の撚が１５８０／Ｊ５ Ｔ／ＩＩ＋以下の場合
、撚の影害を余り受けず被覆糸自体の合成繊維の素材が
有する外観に近くなり。This diffused reflection gives it an appearance similar to silk. Here, it is preferable that the fineness of the core yarn of one elastic yarn is 10D to 40D, and the fineness of the covering yarn is an ultrafine fineness of 5D to 15D, in order to obtain a luxurious silky luster as long socks for women. Anything other than this is undesirable because the product value decreases. Further, when the twist of the covered yarn is 1580/J5 T/II+ or less, the appearance is not affected by the twist so much that it approaches the appearance of the synthetic fiber material of the covered yarn itself.
換言すればフラットヤーンの場合の外観と近くなって好
ましくない。一方、被覆糸の撚が１５８００／Ｊ ７７
ｍ以上の場合、撚が起因する乱反射が強すぎて、絹のよ
うな光沢とかけ離れた結果となると共に、凹凸も大きく
なり過ぎて触感的には絹のようなしなやかさは失われて
好ましくない。In other words, the appearance is similar to that of flat yarn, which is not desirable. On the other hand, the twist of the covered yarn is 15800/J 77
If it is more than m, the diffused reflection caused by twisting will be too strong, resulting in a result that is far from silk-like luster, and the unevenness will also become too large, which is undesirable as it will lose its silk-like suppleness. .
また被覆糸は、乾熱ヒータで機上ヒートセットが施され
ているので、蒸熱ヒートセットと比較して絹に近い自然
の光沢が得られる。Furthermore, since the covered yarn is heat set on the machine using a dry heat heater, a natural luster closer to that of silk can be obtained compared to steam heat set.
ところで、被覆糸に撚があるとこの撚が起因する乱反射

ての透明度が著しく向上する。By the way, if the coated yarn is twisted, the twist causes diffuse reflection, so the transparency of one coated elastic yarn itself as shown in Figure 1 is compared to when the coated yarn is a flat yarn as shown in Figure 6. and somewhat inferior. However, the appearance of this covered elastic yarn itself is somewhat rounded compared to flat yarn due to twisting, so when this rounded yarn is knitted on a knitting machine, the stitches are As shown in Fig. 7, which was photographed under magnification using a microscope, the voids between adjacent stitches are larger than in the case of the conventional flat yarn shown in Fig. 8, and as a result, the porosity increases. The transparency of the product as a whole is significantly improved.
また、被覆糸に乾熱処理を施して８７／ｍ以上２００
Ｔ／ｍ以下のトルクを有するようにするのは。In addition, the coated yarn can be dry heat treated to achieve 87/m or more 200
To have a torque of T/m or less.

上げ工程での熱セント余力も失い商品価値は低下する。First, if the torque is 87/m or less, when dry heat treatment is performed,
If the heat setting is more effective than necessary, the texture will be poor, and the product value will decrease due to the loss of heat capacity during the finishing process.

も悪いことから燥業上問題があるからである。This is not preferable because the winding shape deteriorates and the yarn layer collapses easily. On the other hand, if the length is 20,077 m or more, troubles due to snarls are likely to occur in the seventh step and the unwinding property of the package is also poor, causing problems in the drying industry.

しあうような関係になっている。Figure 2 shows an example of a double covering yarn, in which the inner covering yarn 4 and the outer covering yarn 2 are wound around a core yarn 1 made of elastic yarn so that the twist directions are opposite. The relationship is such that the torque caused by these coverings alone cancels each other out on the inside and outside.

。These coated elastic yarns are manufactured on a covering machine shown in FIG. That is, first, the elastic yarn 1 serving as the core yarn is pulled out by the feed roller 5 and fed into the hollow spindle 6. On the outside of this hollow spindle 6, there is a covered yarn 4.
A bobbin 7 on which is wound is attached, and as the hollow spindle 6 rotates, the covered yarn 4 unwound from the bobbin 7 is wound around the core yarn 1 which is pulled up through the hollow part.

て。Next, the core yarn 1 around which the covered yarn 4 is wound is fed into the hollow spindle 8, and here the core yarn 1 is fed into the hollow spindle 8 again.
The covered thread 2 is wound around a bobbin 9 attached to the outside of the
is wound around this core yarn 1, and further passed through a top roller 10 and wound up as a package 12 by a take-up roller 11. The above explanation refers to the case of manufacturing the double covering yarn 7 (D) shown in FIG. 2, and in the case of a single covering yarn, the hollow spindle 6 is not shown in FIG. 3.
中空スピンドル８が１個の場合である。This is the case where there is one hollow spindle 8.
ここで、前記芯糸１は、スパンデックス繊維として一般
に言われているポリウレタン系弾性糸が好適であるが、
他の種類の弾性繊維であっても良い。Here, the core yarn 1 is preferably a polyurethane elastic yarn that is generally referred to as spandex fiber.
Other types of elastic fibers may also be used.
しかし、その繊度は婦人長靴下用としては１０Ｄ以上４
０Ｄ以下が好ましく、これ以外であると商品価値が低下
して好ましくない。However, the fineness is 10D or more for women's long socks.
A value of 0D or less is preferable, and values other than this are not preferable because the commercial value decreases.

この被覆糸の繊度は５Ｄ〜１５Ｄの極細繊度糸条が必要
である。これ以外では１編地透明性が失われるからであ
る。The coated yarn needs to have an ultrafine fineness of 5D to 15D. This is because, in any other case, the transparency of the knitted fabric will be lost.

, /i15" If it is less than 77m, it will not be affected by twisting much and the appearance will be close to that of the synthetic fiber material of the covered yarn itself,
In other words, the appearance is similar to that of flat yarn, which is not desirable. On the other hand, the twist of the covered yarn is 15800//i5"
When T/m or more, the diffused reflection caused by twisting is too strong, resulting in a result that is far from silk-like luster.

て表すものである。Note that the torque referred to here refers to the rotational twist of the yarn, and a yarn that has been sufficiently heat-set has less torque. This measurement method involves lowering a weight of 0.1 g/D to the center of a 1 m thread, aligning both ends at the center, rotating freely for 5 minutes, and then measuring 0.1 g/D at the center, excluding 0.125 m above and below. The number of turns of 25 m of yarn is measured. The average value of 10 samples is expressed as torque.

９本発明は斜線で示す領域を対象とするものである。FIG. 5 shows the relationship between the fineness of the covered yarn and the torque it has after the covered yarn is heated and heat-treated to stop twisting.9 The present invention is directed to the shaded area.
また被覆糸２は、乾熱ヒータでヒートセットされること
が必要であるが、これは一般的に強撚糸ヲヒートセフト

い自然の光沢が得られなく。In addition, the covered yarn 2 needs to be heat-set with a dry heat heater, but if this is done in a batch system that generally heat-safets highly twisted yarn, it will not be possible to obtain a natural luster similar to that of silk. .
幾分鈍い光沢となるからである。This is because the gloss becomes somewhat dull.
ここで、被覆糸２を乾熱ヒートセットをして製造する場
合の一例を第４図に示す。Here, an example in which the covered yarn 2 is manufactured by dry heat setting is shown in FIG. 4.

The eye guide 24. passes through the spindle center hole, exits from the edge of the spindle disk 23, and balloons the outside of the supply pirn 22. After being twisted through the overfeed roller 25, the guide roller 26
The guide bar 30. It is wound up on a flanged bobbin 32 via a traverse guide 31. In this case, when the heating device 27 applies heat to the twisted yarn, the twist imparted to the yarn is fixed.

That is, if the covered yarn is twisted as shown in Figure 1, the single covered yarn itself is inferior to the case where the covered yarn is a flat yarn as shown in Figure 6 due to the diffused reflection caused by this twist. It is. However, because the coated elastic yarn itself is twisted, it has a somewhat rounded appearance compared to the coated elastic yarn when flat yarn is used, so this rounded yarn is knitted with a knitting machine. As shown in Fig. 7, the gap between adjacent stitches is the 8th stitch.
Compared to the case where the conventional flat yarn shown in the figure is used, the porosity increases, and as a result, the transparency of the product as a whole increases significantly.

人長靴下に適合したものが得られた。Next, regarding the dyeability of the covered elastic yarn, there is not a very clear difference between the two yarn bodies of the present invention and the conventional case. However, due to the increased voids between adjacent stitches, the product as a whole has a rich, light tone with even dyeing and uniform dyeing, making it suitable for elegant and luxurious women's long socks. I got what I wanted.
