Description
本発明は芯糸である弾性糸が非弾性糸である被覆糸で被覆された被覆弾性糸及びこの被覆弾性糸を使用した靴下等の足回り製品に関する。 The present invention relates to a coated elastic yarn in which an elastic yarn that is a core yarn is coated with a coated yarn that is a non-elastic yarn, and an undercarriage product such as a sock using the coated elastic yarn.
靴下等の足回り製品は、ズレ落ちし難く、かつ過度の締め付けがなく、足にフィットし、自然に着用できることが望ましい。
一般的に靴下を着用すると日常の動作の中で靴下が着用初期に比べズレ落ちてしまう現象がよくみられる。この靴下がズレ落ちる要因の1つとしてサポート不足が考えられる。そこで、サポート力を強くしてズレ落ちを防止する方法として、従来、靴下の口ゴム部にゴム糸を挿入する方法等が行われてきた。しかし、この方法では、着用中の締め付け力が強くなり、不快感及びさらには過度の締め付けによる血行障害にもつながり、望ましいとは言えない。さらには、挿入するだけでは、ゴム糸と肌面の接する面積も小さいため、摩擦面積が十分に得られず、肌と靴下間の摩擦力の向上という面でも十分な効果は得られなかった。また、脱衣後に靴下の跡形が残るといった問題もある。
It is desirable that undercarriage products such as socks are difficult to slip off, are not excessively tightened, fit the foot, and can be worn naturally.
In general, when socks are worn, a phenomenon in which the socks fall off compared to the initial wear is often seen in daily operations. One of the factors that cause the socks to fall off is a lack of support. Therefore, as a method for strengthening the support force and preventing slippage, a method of inserting a rubber thread into a mouth rubber part of a sock has been conventionally performed. However, this method is not desirable because the tightening force during wearing is increased, leading to discomfort and even blood circulation disorders due to excessive tightening. Furthermore, since the area of contact between the rubber thread and the skin surface is small only by insertion, a sufficient friction area cannot be obtained, and a sufficient effect is not obtained in terms of improving the frictional force between the skin and the socks. In addition, there is a problem that traces of socks remain after undressing.
このため、上記のズレ落ちの改善方法として、口ゴム部に摩擦抵抗力の高い部分を配し、締め付け力を上げることなく、肌に接することで、滑りにくい性質を設けた靴下が提案されている(下記特許文献1および2参照)。
上記靴下は、口ゴム部に加熱硬化型または室温硬化型シリコーンゴムによりずり落ち防止層を形成したり、高摩擦塗料を浸透させて肌と靴下の接する部分の摩擦力を高めることでズレ落ち防止効果を付与することが可能となる。これらの靴下は着圧を高めることによるズレ落ち防止とは異なり、着用中の血行障害が防止され、脱衣後の跡形が残らないものの、生地に高摩擦塗料を浸透させたり、または、シリコーンゴムを用いてズレ落ち防止層を形成することにより、口ゴム部に生地伸度が低い部分を形成してしまう。口ゴム部に生地伸度が低い部位が配置されることで、口ゴム部全体としての伸度は低下してしまう。このため、着脱時において、靴下を伸ばす際、生地が伸びにくいため、着用しにくいといった問題が生じてしまう。また、ズレ落ち防止層を形成しない場合に比べて生地の戻りが悪くなってしまうため、フィット感が悪くなったり、十分な着圧が得られないといった問題も少なからず生じてしまう。
For this reason, as a method of improving the above-mentioned slipping off, a sock having a non-slip property has been proposed by arranging a portion having a high frictional resistance on the mouth rubber portion and contacting the skin without increasing the tightening force. (See
The above socks prevent slip-off by forming a slip-prevention layer with heat-curing or room-temperature-curing silicone rubber on the mouth rubber part, or by increasing the frictional force of the part where the skin contacts the sock by penetrating a high-friction paint. An effect can be imparted. These socks are different from prevention of slipping off by increasing the wearing pressure, and blood circulation troubles are prevented during wearing, and there is no trace after undressing, but high friction paint penetrates the fabric or silicone rubber is used. By using it and forming the slip-off preventing layer, a portion having a low fabric elongation is formed in the mouth rubber portion. By disposing a portion having a low fabric elongation in the mouth rubber part, the degree of elongation as a whole of the mouth rubber part is lowered. For this reason, at the time of attaching and detaching, when the sock is stretched, the fabric is not easily stretched, which causes a problem that it is difficult to wear. Moreover, since the return of the fabric is worse than when no slip-off prevention layer is formed, there are a number of problems that the fit is not good and sufficient wearing pressure cannot be obtained.
本発明は、着脱性及びフィット感を損なうことなく、着用中の血行障害や脱衣後の跡形形成がなく、且つズレ落ちし難い靴下等の足回り製品の製造に適した被覆弾性糸及びこの被覆弾性糸を口ゴム部に編み込んだ靴下等の足回り製品の提供を目的としている。 The present invention relates to a coated elastic yarn suitable for the production of undercarriage products such as hosiery, which does not impair attachment / detachment and fit, does not cause blood circulation during wearing, does not form a trace after undressing, and is difficult to slip off, and this coating The purpose is to provide undercarriage products such as socks in which elastic yarn is knitted into the rubber band.

Suspension products such as socks that do not easily fall off can be provided.
以下、本発明について詳細に説明する。
本発明の被覆弾性糸は、太繊度の弾性糸に細繊度の非弾性糸を所定の条件にて被覆することで、被覆される弾性糸の露出面積を大きくすることが可能となる。これにより、被覆弾性糸の摩擦係数を高くすることが可能となり、靴下等の足回り製品に編み込んだ際に十分な滑り止め効果を得ることができる。且つ、弾性糸に所定の糸を使用することで、従来の着脱性を損なうことなく、且つ十分な着圧及び滑り止め効果を得ることができる。また、編機を使用して、この被覆弾性糸を靴下の口ゴム部に編みこむで、摩擦力の高い部位を編成することが可能となる。
Hereinafter, the present invention will be described in detail.
In the coated elastic yarn of the present invention, it is possible to increase the exposed area of the elastic yarn to be coated by coating the non-elastic yarn of fine fineness on the elastic yarn of fine fineness under predetermined conditions. As a result, the friction coefficient of the coated elastic yarn can be increased, and a sufficient anti-slip effect can be obtained when knitted into an undercarriage product such as a sock. In addition, by using a predetermined yarn as the elastic yarn, it is possible to obtain a sufficient contact pressure and anti-slip effect without impairing conventional detachability. Further, by using the knitting machine and knitting the covered elastic yarn into the mouth rubber part of the sock, it becomes possible to knitting a portion having a high frictional force.
靴下がズレ落ちる原因としては、靴下にかかる自重、筋肉が収縮することによる周方向の形状変化による摩擦抵抗力の変化、足及び足首が動くことにより靴下身生地が伸長を繰り返されることによる引張力が考えられ、この3つの複合要因からなるズレ落ちようとする力が、靴下のサポート力を上回ることでズレが生じると考えられる。ここでいう靴下のサポート力とは、一般的に着圧とされている周方向の締付力、足と靴下との摩擦力及び靴下自身の形態保持性の複合と考えられる。 Causes of slipping off the sock include its own weight on the sock, changes in frictional resistance due to changes in the shape of the circumference due to contraction of the muscles, tensile force due to repeated stretching of the sock body fabric due to movement of the feet and ankles It is conceivable that the displacement caused by the three combined factors exceeds the support force of the socks so that the displacement occurs. The sock support force here is considered to be a combination of a circumferential tightening force, which is generally applied pressure, a frictional force between the foot and the sock, and the sock shape retention.
一般的にサポート力を強めようとすると、ゴム糸を口ゴム部に挿入したり、ゴム糸の繊度を大きくして、周方向の締付力を強くする方法が考えられる。しかし、これによりサポート力は高まるものの、過度の締め付けにより血行障害につながったり、着用時の圧迫感及び脱衣時に足に跡が残るといった問題が生じる。 In general, in order to increase the support force, a method of increasing the tightening force in the circumferential direction by inserting a rubber thread into the rubber band portion or increasing the fineness of the rubber thread can be considered. However, although this increases support power, problems such as excessive blood flow resulting in impaired blood circulation, a feeling of pressure during wearing, and a mark on the foot during undressing occur.
また、別の方法としてサポート力を強めるため、足と靴下との摩擦力を高める方法がある。この方法として、高摩擦塗料やシリコーンゴム等を口ゴム部に塗布及び浸透させ、摩擦力の高い部分を配することで、肌と靴下との摩擦力を高める方法が一般的であるが、高摩擦塗料やシリコーンゴム等を口ゴム部に塗布及び浸透にさせることで、所定部の生地伸度が低下してしまい、着脱時において、靴下を伸ばす際、生地が伸びにくいため、着脱しにくいといった問題が生じてしまう。
また、身生地に比べて生地の戻りが悪くなってしまうため、フィット感が悪くなったり、十分な着圧が得られないといった問題も少なからず生じてしまう。
As another method, there is a method of increasing the frictional force between the foot and the sock in order to increase the support force. As this method, a method of increasing the frictional force between skin and socks by applying and penetrating high friction paint or silicone rubber to the mouth rubber part and arranging a part with high frictional force is common. By applying and penetrating friction paint, silicone rubber, etc. to the mouth rubber part, the fabric elongation of the predetermined part will decrease, and when stretching the sock when attaching and detaching, it is difficult to attach and detach, Problems arise.
In addition, since the return of the fabric is worse than that of the body fabric, there are not a few problems such as a poor fit and a lack of sufficient pressure.
上記を踏まえ、本発明者らは、所定の被覆条件にて作成した被覆弾性糸を靴下等の製品の口ゴム部に滑り止めとして編み込むことで、着脱性を損なうことなく、十分な滑り止め効果を付与することができることを見出した。 Based on the above, the present inventors have knitted the coated elastic yarn created under the predetermined coating conditions as a non-slip into the mouth rubber part of a product such as a sock, so that a sufficient anti-slip effect is obtained without impairing detachability. It was found that can be imparted.
また、本発明の被覆弾性糸を編みこむ対象である足回り製品とは靴下、タイツおよびレギンス等の足に着用する製品を言う。これらの足回り製品において、着用時に体の胴部に近い部分の開口部付近に本発明の被覆弾性糸を編みこむことで、着脱性を損なうことなく、十分な滑り止め効果を付与することができることを見出した。 The undercarriage product to be knitted with the coated elastic yarn of the present invention refers to a product worn on a foot such as socks, tights and leggings. In these undercarriage products, by knitting the coated elastic yarn of the present invention in the vicinity of the opening portion near the body of the body when worn, it is possible to provide a sufficient anti-slip effect without impairing detachability. I found out that I can do it.
本発明の被覆弾性糸は、繊度が400dtex〜1240dtexのポリウレタン弾性糸を芯糸に配し、非弾性糸を鞘糸に配したカバーリング糸であり、ポリウレタン弾性糸の繊度をAとし、非弾性糸の繊度をBとした時、A/Bが15〜80であることを特徴とする被覆弾性糸である。また、鞘糸の非弾性糸の撚り数が100〜500T/mであり、芯糸であるポリウレタン弾性糸から被覆している非弾性糸を解撚し、該弾性糸及び該非弾性糸をたるみのない状態にした時の該弾性糸の長さをC、該非弾性糸の長さをDとしたとき、1.0≦D/C≦1.7としたカバーリング条件にて作成された被覆弾性糸であることが好ましい。 The coated elastic yarn of the present invention is a covering yarn in which a polyurethane elastic yarn having a fineness of 400 dtex to 1240 dtex is arranged in the core yarn and an inelastic yarn is arranged in the sheath yarn, and the fineness of the polyurethane elastic yarn is set to A. A coated elastic yarn, wherein A / B is 15 to 80, when the fineness of the yarn is B. Further, the number of twists of the non-elastic yarn of the sheath yarn is 100 to 500 T / m, the non-elastic yarn coated from the polyurethane elastic yarn as the core yarn is untwisted, and the elastic yarn and the non-elastic yarn are slackened. Covered elasticity created under the covering conditions of 1.0 ≦ D / C ≦ 1.7, where C is the length of the elastic yarn when not in use and D is the length of the non-elastic yarn A yarn is preferred.
本発明において、芯糸であるポリウレタン弾性糸の繊度は400dtex〜1240dtexであることが肝要であり、望ましくは、450dtex〜1000dtexである。ポリウレタン弾性糸の繊度が400dtex未満である場合、非弾性糸で被覆した場合、露出するポリウレタン弾性繊維の露出面積が小さいため、肌に触れる面積が小さくなる。これにより、ズレ落ちに対して、十分な摩擦力が得られないため、十分なズレ落ち抑制効果が得られない。また、ポリウレタン弾性糸の繊度が1240dtexを超える場合は、ポリウレタン弾性糸の繊度が太くなりすぎることから、被覆弾性糸にした後、靴下等に編み込む際、操作性に乏しいという問題や、被覆弾性糸のパワーが強くなりすぎるため、締付力が高くなり、サポート力は高まるものの、過度の締め付けにより血行障害につながったり、着用時に圧迫感を感じたり、脱衣時に足に跡が残るといった問題が生じる。 In the present invention, it is essential that the fineness of the polyurethane elastic yarn as the core yarn is 400 dtex to 1240 dtex, and preferably 450 dtex to 1000 dtex. When the fineness of the polyurethane elastic yarn is less than 400 dtex, when it is covered with the non-elastic yarn, the exposed area of the exposed polyurethane elastic fiber is small, so the area touching the skin becomes small. Thereby, since sufficient frictional force cannot be obtained with respect to the slippage, a sufficient slippage suppression effect cannot be obtained. In addition, when the fineness of the polyurethane elastic yarn exceeds 1240 dtex, the fineness of the polyurethane elastic yarn becomes too thick. Therefore, when the yarn is made into a covered elastic yarn and then knitted into a sock or the like, The power of the body becomes too strong, but the tightening force is increased and the support force is increased. However, excessive tightening may lead to blood circulation problems, a feeling of pressure when worn, and a mark on the foot when undressed. .
本発明の被覆弾性糸は、ポリウレタン弾性糸の繊度をAとし、非弾性糸の繊度をBとした時、A/Bが15〜80であることが肝要であり、望ましくは、A/Bが25〜80である。
繊度比であるA/Bが15未満の場合は、芯糸であるポリウレタン弾性糸は、露出する面積が小さいため、肌に触れる面積が小さくなる。これにより、ズレ落ちに対して、十分な摩擦力が得られないため、十分なズレ落ち抑制効果が得られない。また、A/Bが80を超えると、弾性糸の露出面積が大きくなりすぎることで、靴下等に編み込む際に操作性に乏しくなると共に、靴下等に編み込んだ際にギラツキ等が発現してしまい審美の低下につながってしまう。
In the coated elastic yarn of the present invention, when the fineness of the polyurethane elastic yarn is A and the fineness of the inelastic yarn is B, it is important that A / B is 15 to 80, and desirably A / B is 25-80.
When the fineness ratio A / B is less than 15, the polyurethane elastic yarn, which is the core yarn, has a small exposed area, so that the area touching the skin is small. Thereby, since sufficient frictional force cannot be obtained with respect to the slippage, a sufficient slippage suppression effect cannot be obtained. Further, if A / B exceeds 80, the exposed area of the elastic yarn becomes too large, and the operability becomes poor when knitting into socks and the like, and glare or the like appears when knitting into socks and the like. This leads to a decline in aesthetics.
本発明の被覆弾性糸は、鞘糸の非弾性糸の撚り数が100〜500T/mであることが望ましい。鞘糸の非弾性糸の撚り数が500T/mを超える場合は、芯糸であるポリウレタン弾性糸は、露出する面積が小さいため、肌に触れる面積が小さくなる。これにより、ズレ落ちに対して、十分な摩擦力が得られないため、十分なズレ落ち抑制効果が得られない。また、撚り数が100T/m未満では、非弾性糸が弾性糸と分離してしまい、操作性に乏しくなってしまう。 In the coated elastic yarn of the present invention, the number of twists of the non-elastic yarn of the sheath yarn is preferably 100 to 500 T / m. When the number of twists of the non-elastic yarn of the sheath yarn exceeds 500 T / m, the exposed area of the polyurethane elastic yarn, which is the core yarn, is small, so that the area touching the skin is small. Thereby, since sufficient frictional force cannot be obtained with respect to the slippage, a sufficient slippage suppression effect cannot be obtained. On the other hand, when the twist number is less than 100 T / m, the inelastic yarn is separated from the elastic yarn, resulting in poor operability.
本発明の被覆弾性糸は、芯糸であるポリウレタン弾性糸から被覆している非弾性糸を解撚し、該弾性糸及び該非弾性糸をたるみのない状態にした時の該弾性糸の長さをC、該非弾性糸の長さをDとしたとき、1.0≦D/C≦1.7であることが望ましい。D/Cが1.7を超える場合は、靴下等に編み込んだ際に、被覆弾性糸のパワーが強く、着脱性が悪くなったり、締め付け力が強くなってしまうといった問題が生じる。また、D/Cが1.0未満の場合では、被覆弾性糸を作製する際に、非弾性糸を伸長して、被覆する必要があり、被覆工程の操作性が著しく低下する。 The coated elastic yarn of the present invention is a length of the elastic yarn when the non-elastic yarn coated from the polyurethane elastic yarn which is the core yarn is untwisted so that the elastic yarn and the non-elastic yarn are not slackened. Is C, and the length of the inelastic yarn is D, it is desirable that 1.0 ≦ D / C ≦ 1.7. When D / C exceeds 1.7, when knitted into socks or the like, there is a problem that the power of the coated elastic yarn is strong, the detachability is deteriorated, and the tightening force is increased. When D / C is less than 1.0, it is necessary to stretch and coat the non-elastic yarn when producing the coated elastic yarn, and the operability of the coating process is significantly reduced.
また、本発明の被覆弾性糸を靴下に編みこんだ部分における靴下の長さ方向の摩擦係数は0.45〜0.70であることが望ましい。さらに望ましくは、0.50〜0.65である。摩擦係数が0.45未満の場合は、肌との摩擦力が低いため、十分なずれ落ち防止効果が望めない。また、摩擦係数が0.70を超える場合は、過度に肌との摩擦が発生してしまい、着用時にべとつきを感じるため、着用感が低下してしまう。 Moreover, it is desirable that the friction coefficient in the length direction of the sock at the portion where the coated elastic yarn of the present invention is knitted into the sock is 0.45 to 0.70. More desirably, it is 0.50 to 0.65. When the friction coefficient is less than 0.45, since the frictional force with the skin is low, a sufficient slip prevention effect cannot be expected. Moreover, when a friction coefficient exceeds 0.70, since friction with skin will generate | occur | produce excessively and it will feel stickiness at the time of wear, a feeling of wear will fall.
また、本発明の被覆弾性糸を靴下に編みこんだ後、当該靴下を使用した後述する引き抜き試験において、引き抜き強度が3300cN〜6000cNあることが望ましい。さらに望ましくは、3700cN〜6000cNである。引き抜き強度は、靴下のサポート力を示しているものである。この場合、サポート力は摩擦力と周方向の締付力の複合力と考えられる。引き抜き強度が3300cN未満の場合は、引っ張り力に対するサポート力が不足するため、ずれ落ち防止に対して十分な効果が望めない。また、引き抜き強度が6000cNを超える場合は、靴下における締め付け力が過度となってしまい、血行障害につながったり、着用時に圧迫感を感じたり、脱衣時に足に跡が残るといった問題が生じる。 Further, after the coated elastic yarn of the present invention is knitted into a sock, it is desirable that the pullout strength is 3300 cN to 6000 cN in a pullout test described later using the sock. More desirably, it is 3700 cN to 6000 cN. The pull-out strength indicates the support force of the socks. In this case, the support force is considered to be a combined force of a friction force and a circumferential tightening force. When the pull-out strength is less than 3300 cN, the support force for the pulling force is insufficient, so that a sufficient effect for preventing the slip-off cannot be expected. Further, when the pull-out strength exceeds 6000 cN, the tightening force in the socks becomes excessive, resulting in a blood circulation disorder, a feeling of pressure when worn, and a mark remaining on the foot when undressed.
本発明の被覆弾性糸の芯糸に使用できるポリウレタン弾性糸としては、乾式紡糸又は溶融紡糸により得られるものが使用できる。ポリウレタン弾性糸の破断伸度は、靴下等に編みこんだ際に良好な伸縮性を有するために、400〜1000%であることが好ましい。
ポリウレタン弾性糸に用いるポリマーは特に限定されないが、ジオール成分として側鎖をもつポリアルキレンエーテルジオールを含有しているものが望ましい。側鎖をもつポリアルキレンエーテルジオールとしては、例えば、同一の炭素上に側鎖として2つのメチル基を有するポリアルキレンエーテルジオールや側鎖として1つのメチル基をを有するポリアルキレンエーテルジオールがあげられる。しかし、これらのポリアルキレンエーテルジオールに限定はされず、ジオール成分の少なくとも一部に側鎖をもつポリアルキレンエーテルジオールが含有されていればよい。
ジオール成分として側鎖を持つポリアルキレンエーテルジオールを含有するポリウレタン弾性糸は、側鎖成分が重合時に立体障害となり、ポリマーの結晶化が抑制され、ソフトストレッチ性を示すため好ましい。
ここで、ポリアルキレンエーテルジオールにおける側鎖は、上記側鎖の中でもメチル基であることが好ましい。エチル基以上の長い側鎖を有すると、側鎖が所望以上の立体障害となり、ポリマーの結晶化が過度に進みにくくなる。このため、十分な結晶化度を得られないため、モジュラスが低く、且つ回復性の悪い糸となってしまうためである。
As the polyurethane elastic yarn that can be used as the core yarn of the coated elastic yarn of the present invention, those obtained by dry spinning or melt spinning can be used. The elongation at break of the polyurethane elastic yarn is preferably 400 to 1000% in order to have good stretchability when knitted in socks or the like.
The polymer used for the polyurethane elastic yarn is not particularly limited, but preferably contains a polyalkylene ether diol having a side chain as a diol component. Examples of the polyalkylene ether diol having a side chain include a polyalkylene ether diol having two methyl groups as side chains on the same carbon and a polyalkylene ether diol having one methyl group as side chains. However, these polyalkylene ether diols are not limited, and it is sufficient that at least a part of the diol component contains a polyalkylene ether diol having a side chain.
A polyurethane elastic yarn containing a polyalkylene ether diol having a side chain as a diol component is preferred because the side chain component becomes a steric hindrance during polymerization, crystallization of the polymer is suppressed, and soft stretch properties are exhibited.
Here, the side chain in the polyalkylene ether diol is preferably a methyl group among the side chains. When the side chain has an ethyl group or longer, the side chain becomes undesired steric hindrance, and the crystallization of the polymer is difficult to proceed excessively. For this reason, since sufficient crystallinity cannot be obtained, it becomes a thread with a low modulus and poor recoverability.
また、本発明に用いるポリウレタン弾性糸には、通常添加される化合物、例えば、紫外線吸収剤、酸化防止剤、光安定剤、耐ガス着色防止剤、耐塩素剤、着色剤、艶消し剤、滑剤、充填剤等が添加されていてもよい。 In addition, the polyurethane elastic yarn used in the present invention is usually added to a compound that is usually added, for example, an ultraviolet absorber, an antioxidant, a light stabilizer, a gas anti-coloring agent, a chlorine-resistant agent, a coloring agent, a matting agent, and a lubricant. In addition, a filler or the like may be added.
本発明の被覆弾性糸における被覆糸である非弾性糸としては、ポリアミド系繊維、ポリエステル系繊維(ポリトリメチレンテレフタレート等)、ポリプロピレン繊維、アクリル系繊維等の合成繊維、キュプラ、レーヨン、綿、竹繊維等のセルロース系繊維、羊毛等の獣毛繊維等、あらゆる繊維の使用が可能である。また、これらの素材で形成されたブライト糸、セミダル糸、フルダル糸等を任意に使用できる。非弾性繊維の断面形状としては丸型、楕円型、W型、繭型、中空糸等任意の断面形状が可能である。また、非弾性繊維の形態は特に限定されず、原糸及び仮撚等を施した捲縮加工糸が使用できる。さらに、長繊維、紡績糸、2種以上の繊維を撚糸、カバーリング、エアー混繊等により混合した複合糸としての使用が可能である。 Examples of the non-elastic yarn that is a coated yarn in the coated elastic yarn of the present invention include polyamide fibers, polyester fibers (polytrimethylene terephthalate, etc.), polypropylene fibers, acrylic fibers and other synthetic fibers, cupra, rayon, cotton, bamboo Any fiber can be used, such as cellulosic fibers such as fibers and animal fibers such as wool. Bright yarns, semi-dal yarns, full-dal yarns and the like formed from these materials can be arbitrarily used. As the cross-sectional shape of the inelastic fiber, any cross-sectional shape such as a round shape, an oval shape, a W shape, a saddle shape, and a hollow fiber is possible.

(6) Deviation measurement method (walking test)
For measurement, after wearing socks on both feet, marking was performed on each foot in the front, back, left, and right at the upper end of the mouth rubber part. Then, after wearing sneakers (Σtef100, manufactured by Moon Star Co., Ltd.) that fits the size of the foot, we walked on the treadmill for 10 minutes at a speed of 4.0 km / h and a walking pace of 110 steps / minute. . Then, from the point marked before walking to the position of the upper end of the rubber band of the sock being worn was measured with 8 points on both feet, and the average value of these 8 points was taken as the amount of slippage of the sock.
(7)比較例1対比ズレ落ち量の算出
口ゴム部に被覆弾性糸を編み込んでいない状態の靴下である比較例1に対するズレ落ち抑制効果をみるため、以下の式にて比較例1対比ズレ落ち量を算出した。
比較例1対比ズレ落ち量[%]=(各実施例及び比較例における靴下でのズレ量(cm)/比較例1の靴下におけるズレ量(cm))×100
上記の式において、比較例1対比ズレ落ち量[%]の値が小さいほど、比較例1に対してズレ落ち量が減少していることを表すため、ズレ落ち効果が高いことを示している。
(7) Computation of the amount of deviation compared with Comparative Example 1 In order to check the effect of suppressing the deviation against Comparative Example 1, which is a sock in which the coated elastic yarn is not knitted in the mouth rubber part, the following example shows the amount of deviation compared with Comparative Example 1. The amount of drop was calculated.
Amount of deviation drop [%] compared to Comparative Example 1 = (Amount of deviation in socks in each Example and Comparative Example (cm) / Amount of deviation in socks of Comparative Example 1 (cm)) × 100
In the above formula, the smaller the value of the deviation drop amount [%] compared to Comparative Example 1, the lower the deviation drop amount compared to Comparative Example 1, which indicates that the deviation drop effect is high. .

[Comparative Example 4]
A polyurethane elastic yarn of 310 dt / 72f having PTMG as the main chain is used as a core yarn, a polyamide fiber of 13 dt / 7f is used as a covering yarn, and the polyurethane elastic yarn is coated at a twist number of 300 T / m.

実施例1〜8は所定の条件の被覆弾性糸を口ゴム部に編み込むことで、肌と靴下の間の摩擦力を上昇させることができ、ズレ低減が可能であった。比較例2〜4に関しては、摩擦力の向上により若干のズレ低減が見られたが、効果が薄い結果となった。 In Examples 1 to 8, the frictional force between the skin and the socks could be increased by knitting a coated elastic yarn under a predetermined condition in the mouth rubber part, and displacement could be reduced. As for Comparative Examples 2 to 4, although slight shift reduction was observed due to the improvement of the frictional force, the results were less effective.
また、着用時のアンケートの結果、実施例1〜3、5及び実施例7,8の靴下においては、比較例1と比べて、着用時の過度の締め付け感はなく、また、着脱容易性も大差ないという結果であった。 Moreover, as a result of the questionnaire at the time of wearing, in the socks of Examples 1 to 3, 5 and Examples 7 and 8, there is no excessive tightening feeling at the time of wearing as compared with Comparative Example 1, and the detachability is also easy. The result was not much different.
実施例4及び6に関しては、ズレ効果は得られたものの、被覆弾性糸のパワーが強く、口ゴムに被覆弾性糸を編みこんでいない比較例1に対して、着脱性が低下する結果であった。 Regarding Examples 4 and 6, although the displacement effect was obtained, the power of the coated elastic yarn was strong, and the result was that the detachability was lowered compared to Comparative Example 1 in which the coated elastic yarn was not knitted into the mouth rubber. It was.
以上より、所定の条件にて作成した被覆弾性糸を靴下等の足回り製品の口ゴム部に編み込むことで、肌と足回り製品間の摩擦力を高めることが可能となり、ズレ落ちを抑制でき、ズレ落ちにくい靴下を代表とする足回り製品を得ることができる。 From the above, we can increase the frictional force between the skin and the undercarriage product by knitting the coated elastic yarn created under the specified conditions into the mouth rubber part of the undercarriage product such as socks, and suppress the slippage. Therefore, it is possible to obtain an underbody product typified by socks that are difficult to slip off.
本発明の被覆弾性糸は摩擦係数が高いので、靴下等の足回り製品に滑り止めとして編み込むことで、着脱性及び着用感を損なうことなく、十分な滑り止め効果を付与することができ、ズレ落ちし難い靴下等の足回り製品の提供が可能となる。 Since the coated elastic yarn of the present invention has a high coefficient of friction, it can be imparted with a sufficient anti-slip effect without impairing detachability and wearing feeling by being knitted into an undersole product such as socks as a non-slip. Suspension products such as socks that do not easily fall off can be provided.
