Description

本発明は、弾性糸を含有する伸長時瞬間的に温度が上昇する編み地、及びこの編み地からなる衣服に関する。   The present invention relates to a knitted fabric containing elastic yarn, whose temperature increases instantaneously when stretched, and a garment made of the knitted fabric.

従来、保温衣料等、着用時に温度が上昇する衣服として、セルロース等の吸湿発熱繊維を混合した布帛により衣服を製造し、着用時の人体からの不感蒸泄や発汗により発熱させる衣服が知られている(例えば下記特許文献1参照)。しかしながら、吸湿発熱繊維は、繊維の吸湿量が飽和に達すればそれ以上発熱することは無く、発熱時間が短いばかりでなく、吸湿量が飽和に達した後は、繊維中の水分により冷感を感じることさえあった。さらに、吸湿発熱以外の発熱布帛や発熱衣服として、面状発熱体や線状発熱体などのヒーターを衣服に組み込むことなどが知られているが、いずれも、電気により発熱するもので、衣服とした際は重くなり、電極も必要で動きにくい衣服となる。   Conventionally, clothes such as heat-insulating clothing that increase in temperature when worn are manufactured using a cloth mixed with moisture-absorbing heat-generating fibers such as cellulose, and heat is generated by insensitive excretion or sweating from the human body when worn. (See, for example, Patent Document 1 below). However, the moisture-absorbing exothermic fiber does not generate any further heat when the fiber's moisture absorption reaches saturation, and not only the heat generation time is short, but also after the moisture absorption reaches saturation, the moisture in the fiber causes a cooling sensation. I even felt it. Furthermore, it is known to incorporate a heater such as a planar heating element or a linear heating element into a garment as a heating fabric or a heating garment other than hygroscopic heat generation. If you wear it, it will be heavy, and you will need an electrode, making it difficult to move.

また、最近では着用動作時の編地伸長時に発熱するという、これまでと全く違った発熱機能を持つ編地が提案されている(例えば下記特許文献2および3参照)。しかしながら、この編み地は、確かに伸長時発熱して暖かいが、弾性糸の含有量が多くなる事により、編み地重量が増し、重い衣服となり動き難く、また、弾性糸の含有量が多いために高コストとなりがちである。これらの解消の為、弾性糸の含有量を少なくすれば、伸張発熱温度が低下するという問題が生じる。   Recently, there have been proposed knitted fabrics having a completely different heat generation function that generates heat when the knitted fabric is stretched during wearing (see, for example, Patent Documents 2 and 3 below). However, this knitted fabric is surely warm and warm when stretched, but because the elastic yarn content increases, the knitted fabric weight increases, it becomes difficult to move into heavy clothes, and the elastic yarn content is high. Tend to be expensive. In order to solve these problems, if the content of the elastic yarn is reduced, there arises a problem that the extension heat generation temperature is lowered.

本発明が解決しようとする課題は、弾性糸を含有する編み地において、伸長時瞬間的に温度が上昇し、編み地の伸縮を繰り返せば持続的に伸長時発熱し、かつ、伸長発熱が効率よく達成され、しかも、動き易い衣服を低コストで製造できる編み地を提供すること、並びに、この編み地を使用してインナー、スポーツウェアなどの衣服を縫製することにより、保温性、伸長部位の筋肉や関節を暖めることによる怪我の防止、及び脂肪燃焼効果を期待できる衣服を提供することである。   The problem to be solved by the present invention is that, in a knitted fabric containing elastic yarn, the temperature rises instantaneously when stretched, and if the knitted fabric is repeatedly expanded and contracted, heat is generated continuously during stretching, and the heat generated by stretching is efficient. By providing a knitted fabric that can be manufactured well at a low cost and that is easy to move, and by using this knitted fabric to sew clothes such as inner and sportswear, It is to provide a garment that can prevent injuries due to warming of muscles and joints and can expect a fat burning effect.

本発明者等は、上記課題を解決すべく鋭意検討し実験を重ねた結果、編地を伸張時発熱させるには、弾性糸の伸長による発熱を利用するのみでは弾性糸の含有量が多くなり、重たく動き難い衣服となるため、衣服、つまり編み地の軽量化を行いつつ編み地の伸長による発熱を低下させない方法について重要な知見を得ることが出来た。つまり、編み地を伸長発熱させるためには、弾性糸の伸長による発熱と、編み地を伸張することによる糸と糸との摩擦による発熱を利用すればよい事を見出した。さらに、これらを最適な範囲にすることにより上記課題を達成でき、非弾性糸と弾性糸とからなる編み地において、弾性糸の含有量が少ないにもかかわらず、伸長時の瞬間発熱温度が1.0℃以上となることを見出し、本発明に至ったものである。   As a result of intensive studies and experiments conducted by the present inventors to solve the above-mentioned problems, in order to generate heat when stretching a knitted fabric, the elastic yarn content increases only by using the heat generated by stretching the elastic yarn. Since the clothes are heavy and difficult to move, it was possible to obtain important knowledge about how to reduce the heat generated by stretching the knitted fabric while reducing the weight of the garment, that is, the knitted fabric. That is, it has been found that in order to generate heat by stretching the knitted fabric, heat generated by stretching the elastic yarn and heat generated by friction between the yarn and the yarn by stretching the knitted fabric may be used. Furthermore, the above-mentioned problems can be achieved by setting these in an optimal range. In a knitted fabric composed of an inelastic yarn and an elastic yarn, the instantaneous heat generation temperature at the time of elongation is 1 despite the low elastic yarn content. The present inventors have found that the temperature is 0.0 ° C. or higher and have reached the present invention.

以下、本発明について詳細に説明する。
本発明は、上述したように、編み地を伸長時発熱させるには、弾性糸の伸長による発熱を利用するのみでは弾性糸の含有量が多くなり、重たく動き難い衣服となるため、弾性糸の含有量を少なくし、衣服、つまり編み地の軽量化を行いつつ編み地の伸長による発熱を低下させない方法について鋭意検討の結果、編み地を伸長発熱させるためには、弾性糸の伸長による発熱と、編み地を伸長することによる糸と糸との摩擦による発熱を利用すればよい事を見出したものである。非弾性糸からなる編み地を大きく伸長させるほど発熱する事は知られているが、伸長量が大きくなると糸と糸との摩擦による発熱以外に、繊維の延伸による発熱が大きくなり、弾性糸は大きな伸長でも伸長回復して元の長さに復帰するが、非弾性糸を大きく伸長すると繊維そのものが延伸され、ひずみが生じて元の長さに復帰しなくなる。そこで、本発明では、衣服の着用伸長程度、すなわち、非弾性糸が延伸されることなく、繊維のひずみも生じない伸長領域でも十分発熱させるために、弾性糸の伸長発熱の利用と、弾性糸の伸長発熱では十分発熱しない場合には、発熱を補完するために糸と糸との摩擦熱を利用することを考案したもので、これにより、弾性糸の含有量が少なく、弾性糸のみの伸長発熱では発熱が不十分な場合でも、暖かい衣服とすることが可能となった。糸と糸との摩擦による発熱は、弾性糸の発熱を補完するものであって、弾性糸の伸長発熱が重要であることには変わりなく、また、弾性糸のみでの伸長発熱が十分である場合でも、さらに高い発熱温度が得られ、より暖かい衣服とすることが出来、その為の編み地の構成要件について以下に詳細に示す。
Hereinafter, the present invention will be described in detail.
As described above, according to the present invention, in order to generate heat when the knitted fabric is stretched, the elastic yarn content is increased only by using heat generated by stretching of the elastic yarn, resulting in a heavy and difficult-to-move garment. As a result of intensive studies on the method of reducing the content and reducing the heat generation due to the elongation of the knitted fabric while reducing the weight of the garment, that is, the knitted fabric, It has been found that heat generated by friction between the yarn and the yarn caused by stretching the knitted fabric may be used. It is known that heat is generated as the knitted fabric made of inelastic yarn is greatly stretched.However, when the amount of stretch is increased, heat generated by stretching of the fiber increases in addition to heat generated by friction between the yarn and the yarn. Even if the stretch is large, the stretch is recovered and returns to the original length. However, when the inelastic yarn is stretched greatly, the fiber itself is stretched and strain is generated, so that it does not return to the original length. Therefore, in the present invention, in order to sufficiently generate heat even in an elongation region where the clothes are stretched and worn, that is, the inelastic yarn is not stretched and the fiber is not distorted, the elastic yarn is used. In the case where the heat generation is not enough, the frictional heat between the yarn and the yarn is devised to compensate for the heat generation, so that the elastic yarn content is low and only the elastic yarn is stretched. Even if fever is insufficient, it is possible to wear warm clothes. The heat generated by friction between yarns complements the heat generated by the elastic yarns, and the heat generated by the elastic yarns is important. The heat generated by the elastic yarns is sufficient. Even in this case, a higher heat generation temperature can be obtained, and warmer clothing can be obtained. The constituent requirements of the knitted fabric for this purpose will be described in detail below.

本発明の編み地は、緯編み地では釜径30〜40インチ程度の大口径のシングル丸編機、ダブル丸編機、釜径4インチ程度ストッキング編機、釜径13〜17インチの小寸編機等、26〜40ゲージ程度の丸編機、及び、ハイゲージの横編機により製造される非弾性糸と弾性糸とからなる緯編み地であり、経編み地では、26〜40ゲージの複数筬の経編機により製造される非弾性糸と弾性糸とからなる経編み地であり、これらの編み地は、弾性糸の含有量が15〜50g/m2とし、加えて編み地充填率が20〜30%となるように編み地の設計を行う。伸張発熱には、弾性糸の伸長時の発熱が重要であるが、弾性糸の伸長発熱を補うためには、編み地中の糸と糸との摩擦を活かせば弾性糸の含有量を少なくすることが可能で、その為、編み地充填率を20〜30%とすれば、効果的に糸と糸との摩擦が生じ、弾性糸の伸長発熱を補完することが出来る。本発明でいう編み地充填率とは、布帛の外側を直線でつないで形成される体積のうち、繊維が占める体積をいい、編み地充填率が20%未満では、糸と糸との摩擦による発熱が小さく、弾性糸の伸長発熱を補完する効果が得られない。逆に、編み地充填率大きくなると伸び難い編地となり、編み地充填率が30%より大きくなるとほとんど伸びない編み地となり、伸長発熱しない編み地となるばかりでなく、着用時動き難い衣服となる。従い編み地充填率は20〜30%、より好ましくは22〜28%とすればよい。
また、糸と糸の摩擦熱を大きくするためには、仮撚り等の加工糸の使用、紡績糸の使用、撚糸の使用、2種以上の繊維の混繊糸の使用、被覆弾性糸の使用等、繊維表面の摩擦が大きい糸の使用により、糸と糸との摩擦熱が高くなり、編み地充填率が低い場合は、これらの繊維の使用を考慮すればよい。
The knitted fabric of the present invention is a single circular knitting machine, a double circular knitting machine, a stocking knitting machine having a hook diameter of about 4 inches, and a small diameter of a hook diameter of 13 to 17 inches. It is a weft knitted fabric made of inelastic yarn and elastic yarn manufactured by a circular knitting machine of about 26 to 40 gauge, such as a knitting machine, and a high gauge flat knitting machine. A warp knitted fabric made of a non-elastic yarn and an elastic yarn manufactured by a plurality of warp knitting machines. These knitted fabrics have an elastic yarn content of 15 to 50 g / m 2 and are additionally filled with a knitted fabric. The knitted fabric is designed so that the rate is 20 to 30%. Heat generation at the time of elastic yarn elongation is important for stretching heat generation, but to compensate for elastic yarn elongation heat generation, the friction between the yarn in the knitted fabric is utilized to reduce the elastic yarn content. Therefore, if the filling rate of the knitted fabric is 20 to 30%, friction between the yarn and the yarn is effectively generated, and the elongation heat generation of the elastic yarn can be complemented. The knitted fabric filling rate referred to in the present invention refers to the volume occupied by the fibers in the volume formed by connecting the outside of the fabric with a straight line. When the knitted fabric filling rate is less than 20%, the knitted fabric filling rate is due to friction between the yarn and the yarn. The heat generation is small, and the effect of complementing the elongation heat generation of the elastic yarn cannot be obtained. Conversely, when the filling rate of the knitted fabric is increased, the knitted fabric is difficult to stretch, and when the filling rate of the knitted fabric is higher than 30%, the knitted fabric is hardly stretched. . Therefore, the knitted fabric filling rate may be 20 to 30%, more preferably 22 to 28%.
In order to increase the frictional heat between yarns, use of processed yarn such as false twist, use of spun yarn, use of twisted yarn, use of mixed fiber of two or more types of fibers, use of coated elastic yarn In the case where the frictional heat between the yarn and the yarn increases due to the use of the yarn having a large friction on the fiber surface and the knitted fabric filling rate is low, the use of these fibers may be considered.

本発明において、編み地充填率の求め方は、標準状態(20℃65%RH)の環境下で、編み地の目付と厚みを測定し、下記式にて編み地充填率を求める。
充填率(%)=(M/L)÷(H1×K1+H2×K2+・・+Hn×Kn)×100
上式において、LはKES圧縮試験機で測定した荷重6g/cm2での厚み(cm)であり、Mは単位面積当たりの重量(g/cm2)であり、H1、H2・・Hnは編み地が含有する繊維1、2・・n各々の比重であり、K1、K2・・Knは編み地が含有する繊維1、2・・n各々の混率である。なお、繊維の比重については、繊維便覧第3版(丸善)による繊維の比重を使用し、比重に幅がある繊維については中間値を使用し、編地の混率の数値は例えば混率80%の場合は数値0.80を使用する。また、充填率は、得られた数値の小数点以下一桁目を四捨五入し整数で示す。
In the present invention, the knitted fabric filling rate is determined by measuring the basis weight and thickness of the knitted fabric in an environment of a standard state (20 ° C. and 65% RH), and obtaining the knitted fabric filling rate by the following formula.
Filling rate (%) = (M / L) ÷ (H1 × K1 + H2 × K2 + ·· + Hn × Kn) × 100
In the above equation, L is a thickness (cm) at a load of 6 g / cm 2 measured with a KES compression tester, M is a weight (g / cm 2 ) per unit area, and H1, H2,. The specific gravity of each of the fibers 1, 2, ·· n contained in the knitted fabric, and K1, K2, ··· Kn are the mixing ratio of the fibers 1, 2, ·· n contained in the knitted fabric. For the specific gravity of the fiber, the specific gravity of the fiber according to the 3rd edition of the Fiber Handbook (Maruzen) is used. For the fiber having a wide specific gravity, an intermediate value is used. The mixing ratio of the knitted fabric is, for example, 80% mixing ratio. In this case, the numerical value 0.80 is used. The filling rate is expressed as an integer by rounding off the first decimal place of the obtained numerical value.

本発明による編み地中の弾性糸の含有量については、糸と糸との摩擦による発熱の補完があるため少なくすることが可能で、弾性糸の含有量が少なく伸長発熱温度が低かった編み地も伸長発熱温度が高くなり、また、弾性糸の含有量が多くて伸長発熱していた編み地も、より高い伸長発熱するようになる。従い、弾性糸の含有量は15〜50g/m2、好ましくは16〜48g/m2とし、弾性糸の含有量が15g/m2未満では、編み地中の糸と糸の摩擦が大きくても高い伸長発熱温度が得られない。また、弾性糸の含有量が50g/m2より多いと重くて動き難い衣服となり、また高コストとなるため本発明の目的は達成できない。 The content of the elastic yarn in the knitted fabric according to the present invention can be reduced because of the supplement of heat generation due to friction between the yarn and the yarn, and the knitted fabric has a low elastic yarn content and a low elongation heat generation temperature. Further, the elongation heat generation temperature becomes high, and the knitted fabric having a large content of elastic yarn and generating heat is also generating higher heat generation. Accordingly, the elastic yarn content is 15 to 50 g / m 2 , preferably 16 to 48 g / m 2 , and if the elastic yarn content is less than 15 g / m 2 , the friction between the yarn and the yarn in the knitted fabric is large. However, a high elongation exothermic temperature cannot be obtained. On the other hand, if the content of the elastic yarn is more than 50 g / m 2 , the clothes become heavy and difficult to move, and the cost is high, so the object of the present invention cannot be achieved.

さらに、本発明の編み地について、衣服着用時に動き易くなるよう、なるべく少ない弾性糸の含有量でより伸長発熱する編み地設計について検討した結果、本発明者らは、後述する方法で測定した編み地の応力比の範囲が重要であり、その範囲の応力比を達成する手段を見出した。
例えば、弾性糸は伸長される際発熱し、伸長緩和時吸熱され、完全な弾性体、すなわち、伸長時と伸長緩和時の伸度―応力曲線(S−Sカーブ)が全く重なっているような弾性体は伸長時の発熱と伸長緩和時の吸熱温度はほぼ同じとなり、つまり、伸長時と伸長緩和時のサイクル全体で発熱量はほぼ0となる。本発明では、編み地の伸長時の発熱温度に対して、伸長緩和時の吸熱を最小限に抑えるための編み地応力比の規定、及び規定した応力比の範囲を達成するための手段を見出したものである。
Furthermore, as a result of studying a knitted fabric design that generates more heat with less elastic yarn content so that the knitted fabric of the present invention can be easily moved when wearing clothes, the present inventors have found that the knitted fabric measured by the method described later is used. The range of the ground stress ratio is important, and a means for achieving the stress ratio in that range has been found.
For example, an elastic yarn generates heat when it is stretched, absorbs heat when it is relaxed, and a complete elastic body, that is, an elongation-stress curve (SS curve) when stretched and when relaxed is completely overlapped. The elastic body has substantially the same heat generation at the time of extension and endothermic temperature at the time of extension relaxation, that is, the heat generation amount becomes almost zero in the entire cycle at the time of extension and extension relaxation. In the present invention, a means for achieving a specified knitted fabric stress ratio and a specified stress ratio range for minimizing the endotherm during elongation relaxation with respect to the exothermic temperature during stretching of the knitted fabric is found. It is a thing.

応力比については、最適な条件があり、すなわち、伸縮時の応力比は0.40〜0.80であることが極めて重要である。一般の編み地の応力比は0.80超であるが、応力比が0.80より大きいと伸長時発熱しても伸長緩和時に吸熱現象が生じ、結果として発熱が小さくなりやすい。また、応力比が0.40未満の場合は、伸長時発熱は高くなるが、衣服とした際、肘や膝の関節部を曲げ伸ばしした後に編み地が変形して衣服が型崩れして好ましくなく、さらに、応力比が高すぎる場合には、伸長発熱温度そのものが低くなる。従って、応力比は、0.45〜0.75が好ましく、0.45〜0.70がさらに好ましい。なお、経方向と緯方向で応力比が異なる場合は両方向とも上記の範囲に入っていることが好ましいが、伸長発熱性能を発揮させたい方向のみ、応力を上記範囲とすることも可能で、ただしこの場合、衣服を縫製して着用した際に、動作により編み地が伸長される方向が上記範囲であることが好ましい。応力比のコントロールは弾性糸の含有量、弾性糸そのものの応力比(弾性糸の80%伸長時における伸縮50%での往復の応力比)、弾性糸と非弾性糸との繊度比、編み地充填率、編み地の滑り性により、応力比のコントロールが可能である。   There are optimum conditions for the stress ratio, that is, it is extremely important that the stress ratio during expansion and contraction is 0.40 to 0.80. The stress ratio of a general knitted fabric is more than 0.80. However, if the stress ratio is greater than 0.80, an endothermic phenomenon occurs at the time of elongation relaxation even if heat is generated during elongation, and as a result, heat generation tends to be small. In addition, when the stress ratio is less than 0.40, the heat generation at the time of elongation is high. However, when the garment is used, it is preferable that the knitted fabric is deformed after bending the elbow and knee joints and the garment is deformed. Furthermore, if the stress ratio is too high, the extensional heat generation temperature itself becomes low. Therefore, the stress ratio is preferably 0.45 to 0.75, and more preferably 0.45 to 0.70. When the stress ratio is different between the warp direction and the weft direction, it is preferable that both directions are within the above range, but the stress can be within the above range only in the direction in which the extension heat generation performance is desired, In this case, when the garment is sewn and worn, the direction in which the knitted fabric is stretched by the operation is preferably within the above range. The stress ratio is controlled by the elastic yarn content, the stress ratio of the elastic yarn itself (reciprocating stress ratio at 50% expansion and contraction when the elastic yarn is stretched 80%), the fineness ratio of the elastic yarn and the inelastic yarn, and the knitted fabric The stress ratio can be controlled by the filling rate and the slidability of the knitted fabric.

応力比のコントロールの例として、応力比を小さくするには、弾性糸と非弾性糸との繊度比を大きくする、加工糸、紡績糸、複合糸等の使用、一般的な弾性糸より小さい応力比の弾性糸を使用しての編み地作製、さらに、編み地充填率を高くする等の方法がある。あるいは、編み地の染色仕上げ時でも応力比のコントロールが可能で、特に、ヒートセット時の加熱条件を強くすることが効果的で、通常のセット温度よりも若干高くして、190〜195℃でのヒートセットが好ましく、セット温度を高くできない場合は、セット時間を通常のセット時間より長くすればよく、例えば、70〜90秒程度とするのが好ましい。さらに、編み地が滑りやすくなるように仕上げれば応力比が小さくなり易い。仕上げ剤で具体的に示すと、シリコン系の平滑剤は使用しないことが好ましく、例えば、ポリエステル系の仕上げ剤や、仕上げ剤を使用しないで仕上げることにより応力比を規定の範囲に収めやすい。これらの様に、応力比のコントロールは種々の方法により可能で、製造しようとする目標編み地に応じて1種以上選定すればよい。   Examples of stress ratio control include reducing the stress ratio by increasing the fineness ratio of elastic and inelastic yarns, using processed yarns, spun yarns, composite yarns, and stresses that are smaller than general elastic yarns. There are methods for producing a knitted fabric using an elastic yarn having a specific ratio and increasing the filling rate of the knitted fabric. Alternatively, it is possible to control the stress ratio even at the dyeing finish of the knitted fabric. In particular, it is effective to strengthen the heating conditions at the time of heat setting, and it is slightly higher than the normal setting temperature at 190 to 195 ° C. When the set temperature cannot be raised, the set time may be set longer than the normal set time, for example, about 70 to 90 seconds is preferable. Furthermore, if the knitted fabric is finished so as to be slippery, the stress ratio tends to be small. Specifically, it is preferable not to use a silicon-based smoothing agent as a finishing agent. For example, the stress ratio is easily within a specified range by finishing without using a polyester-based finishing agent or a finishing agent. As described above, the stress ratio can be controlled by various methods, and one or more types may be selected according to the target knitted fabric to be manufactured.

本発明でいう応力比は、編み地を80%まで伸長後元の長さに戻し、伸縮途中の50%時点での往路応力と復路応力を求め、下記式により、少数点以下3桁目を四捨五入して求める。
応力比=(50%時点の復路応力(N))/(50%時点の往路応力(N))
尚、編み地を80%まで伸長して伸縮途中の応力で応力比を求めるが、編み地伸度が低くて80%まで伸長困難な場合は、60%まで伸長して伸長後元の長さに戻し、伸縮途中の50%時点での往路応力と復路応力から応力比を求める。
なお、応力比を伸長、及び、回復50%時点での応力により求めるのは、50%時点の応力比が編み地伸長時に発熱した温度と、伸長回復時に吸熱する温度との差を捉えやすいことを見出したからである。すなわち、応力比が小さいほど弾性糸の伸長緩和時の吸熱温度が低く、高い伸長発熱温度が得られ、編み地の伸長時の発熱に対して、伸長緩和時の吸熱を最小限に抑える指標とすることが可能となる。
The stress ratio as used in the present invention is that the knitted fabric is stretched to 80% and then returned to the original length, and the forward stress and the return stress at the time of 50% during the expansion and contraction are obtained. Calculate by rounding off.
Stress ratio = (Return stress at 50% (N)) / (Outward stress at 50% (N))
The knitted fabric is stretched to 80%, and the stress ratio is determined by the stress during stretching. If the knitted fabric has a low elongation and it is difficult to stretch to 80%, it stretches to 60% and the original length after stretching. The stress ratio is obtained from the outward stress and the backward stress at the time of 50% during expansion and contraction.
Note that the stress ratio is obtained from the stress at the time of elongation and recovery 50% because the stress ratio at the time of 50% easily captures the difference between the temperature at which heat is generated when the knitted fabric is stretched and the temperature at which heat is absorbed at the time of recovery from elongation. It is because it found out. In other words, the smaller the stress ratio, the lower the endothermic temperature when the elastic yarn is stretched and relaxed, and a higher elongation heat generation temperature is obtained. It becomes possible to do.

本発明の編み地は、経緯少なくとも一方向の伸長時瞬間発熱温度が1.0℃以上であることを特徴とするが、本発明における瞬間発熱温度とは、伸縮以外に外部からのエネルギー供給がなく、風による伸長発熱温度が変化しない条件下で、編み地を60〜100%伸長し、次いで緩和してもとの長さに戻す工程を1回とする繰り返し伸縮を100回行う間に編み地が示す最高温度をサーモグラフィで測定し、試験開始前の編み地温度との差から算出された値である。   The knitted fabric of the present invention is characterized in that the instantaneous exothermic temperature at the time of elongation in at least one direction is 1.0 ° C. or more, but the instantaneous exothermic temperature in the present invention is the supply of energy from outside in addition to expansion and contraction. Without stretching the knitted fabric by 60 to 100% under the condition that the elongation heat generation temperature due to wind does not change, knitting during 100 times of repeated expansion and contraction, with the process of returning to the original length once relaxed The maximum temperature indicated by the ground is measured by thermography, and is a value calculated from the difference from the knitted fabric temperature before the start of the test.

100回の60〜100%伸縮中又は伸縮完了直後に、編み地温度が試験開始前の編み地温度より高くなれば、瞬間発熱していることを示す。本発明の編み地は、この方法により測定した瞬間発熱温度が1.0℃以上あることが必要である。1.0℃未満の瞬間発熱温度では、ほとんど発熱を感じられない。瞬間発熱温度は好ましくは1.5℃以上、より好ましくは2.0℃以上である。瞬間発熱温度が高いほど好適であり、人体に悪影響を与えない範囲であれば上限は特に限定されないが、瞬間発熱温度を高くするために弾性繊維の含有量が多く、糸と糸との摩擦を大きくする等の編み地の設計により発熱温度が高くなりすぎると編地がハイパワーとなって衣服として動き難くなるため、瞬間発熱温度は10℃以下であることが好ましい。また、編み地経緯方向のうち、少なくとも一方向の60〜100%伸長時の瞬間発熱温度が1.0℃以上であればよく、編み地の経方向と緯方向の両者とも瞬間発熱温度が1.0℃以上の編み地の場合は、製品縫製時の型入れ方向を特に考慮しなくてもよいが、一方向のみ瞬間発熱する編み地の場合は、人体の関節で特に皮膚伸びが大きい方向を、瞬間発熱が大きい編み地の方向と一致させれば、運動動作時暖かい衣服を製造することができる。   If the knitted fabric temperature becomes higher than the knitted fabric temperature before the start of the test during 100 times of 60 to 100% expansion or contraction, it indicates that instantaneous heat generation has occurred. The knitted fabric of the present invention needs to have an instantaneous heat generation temperature of 1.0 ° C. or higher measured by this method. At an instantaneous heat generation temperature of less than 1.0 ° C., almost no heat generation is felt. The instantaneous heat generation temperature is preferably 1.5 ° C. or higher, more preferably 2.0 ° C. or higher. The upper limit is not particularly limited as long as the instantaneous heat generation temperature is high, and the upper limit is not particularly limited as long as it does not adversely affect the human body, but in order to increase the instantaneous heat generation temperature, the content of elastic fibers is large, and the friction between the yarn and the yarn is reduced. If the heat generation temperature becomes too high due to the design of the knitted fabric such as increasing the size, the knitted fabric becomes high power and it becomes difficult to move as clothes, so the instantaneous heat generation temperature is preferably 10 ° C. or less. Further, the instantaneous heat generation temperature at 60% to 100% elongation in at least one direction of the knitted fabric weft direction may be 1.0 ° C. or more, and the instantaneous heat generation temperature is 1 in both the warp direction and the weft direction of the knitted fabric. For knitted fabrics of 0 ° C or higher, there is no need to take into account the direction of mold insertion when sewing products. However, in the case of knitted fabrics that generate heat instantaneously in only one direction, the direction in which the skin stretches is particularly large at the joints of the human body. Can be made to match the direction of the knitted fabric where the instantaneous heat generation is large, it is possible to produce warm clothes during exercise.

なお、伸長発熱温度測定時の伸長量設定は、初期長10.0cm、幅2.5cmの編み地の9.8N荷重下での編み地伸度により設定し、編み地伸度が100%以上の場合の伸長量は100%、編み地伸度が60%以上100%未満の場合の伸長量は、9.8N荷重下の伸度に0.9倍した値の伸長量とし、例えば、9.8N荷重下の編み地伸度が80%の場合の伸長量は80×0.9=72%として設定する。9.8N荷重下の編み地伸度が経方向又は緯方向のいずれか一方の編み地伸度の60%以上となるよう設計することが必要であり、経方向と緯方向の両方とも伸度が60%未満の場合は、伸び難く伸張発熱しないと言える。9.8N荷重下の編み地伸度の測定法、発熱温度の測定法は、以下の実施例において具体的に説明する。   In addition, the elongation amount setting at the time of measuring the exothermic temperature is set by the knitted fabric elongation under a 9.8N load of a knitted fabric having an initial length of 10.0 cm and a width of 2.5 cm, and the knitted fabric elongation is 100% or more. In this case, the elongation amount is 100%, and when the knitted fabric elongation is 60% or more and less than 100%, the elongation amount is 0.9 times the elongation under a load of 9.8 N, for example, 9 When the elongation of the knitted fabric under 80 N load is 80%, the stretch amount is set as 80 × 0.9 = 72%. It is necessary to design the knitted fabric under a load of 9.8 N so that the elongation of the knitted fabric is 60% or more of either the warp direction or the weft direction. Is less than 60%, it is difficult to elongate, and it can be said that no exothermic heat is generated. The measurement method of the knitted fabric under a load of 9.8 N and the measurement method of the heat generation temperature will be specifically described in the following examples.

弾性糸を含有する従来の編み地は、編み地に伸縮性を持たせ衣服着用時に心地よいフィット感を付与するもので、これにより、スリムな審美性の衣服を得たり、運動機能を向上させたりするものであった。これに対し本発明は、伸縮により発熱をする編み地を得るものであり、従来品とは全く異なる発想の編地である。60〜100%伸長時の瞬間発熱温度を1.0℃以上とするには、弾性糸の含有量、編み地充填率、弾性糸と非弾性糸との繊度比、ループ数、編地の応力比等を適正な範囲とすること、すなわち、糸使い、ループ構造等の編地設計と、伸長発熱を効率的に発揮するための加工法を含めた編み地製造方法とが重要である。本発明により初めて60〜100%伸長時の瞬間発熱温度が1.0℃以上である編み地が得られ、衣服として着用した時に、着用時の人体関節の伸長量である僅か30〜50%の伸長でも高く発熱し、着用時に発熱が実感できるようになったものである。   Conventional knitted fabrics containing elastic yarns give the knitted fabric elasticity and give a comfortable fit when wearing clothes, which makes it possible to obtain slim aesthetic clothing and improve motor function. It was something to do. On the other hand, the present invention obtains a knitted fabric that generates heat by expansion and contraction, and is a knitted fabric of a completely different concept from the conventional product. In order to set the instantaneous heat generation temperature at 60 to 100% elongation to 1.0 ° C. or higher, the content of elastic yarn, the knitted fabric filling rate, the fineness ratio of elastic yarn to inelastic yarn, the number of loops, the stress of the knitted fabric It is important to set the ratio and the like within an appropriate range, that is, a knitted fabric design such as yarn use and loop structure, and a knitted fabric manufacturing method including a processing method for efficiently exhibiting heat generation by extension. According to the present invention, for the first time, a knitted fabric having an instantaneous heat generation temperature of 1.0 ° C. or higher when stretched by 60 to 100% is obtained, and when worn as a garment, the stretch amount of the human joint when worn is only 30 to 50%. High heat is generated even when stretched, and the heat can be felt when worn.

本発明の編み地では、弾性糸の含有量、編み地充填率、応力比に加え、編み地の経方向密度(コース/インチ)と編み地の緯方向密度(ウェール/インチ)との積である編み地のループ数も重要であり、ループ数を特定の範囲内に入れることにより、伸長発熱と編み地の応力とのバランスを最適化できる。本発明による編み地が緯編み地の場合は、ループ数が3000〜8000の範囲内が好ましい。弾性糸の含有量、弾性糸と非弾性糸との繊度比が規定の範囲内であっても伸張発熱温度が低かったり、編み地が高応力となったりすることがある。つまり、ループ数が3000未満では編地の伸度が小さく、また、伸長発熱温度も低く、ループ数が8000より多い場合は編み地が高応力となり、動き難い衣服となる。特に、ループ数が3000未満の場合は、衣服とした際に突っ張り感が高いとともに、編み地の通気性も高くなることがあり、編み地の伸長発熱温度そのものが低いことに加え、伸長発熱しても通気性が高い事より外気の流入が多く暖かく感じない。これらより、ループ数は好ましくは3000〜8000とし、より好ましくは3500〜7500とすればよい。これらループ数のコントロールは、繊度比、編機のゲージとともに、染色加工時の性量コントロールにより可能で、ループ数を大きくするには、繊度比を小さくすること、編機ゲージを密にすること、染色加工で編地を幅入れ、追い込み加工すること等により達成し易い。特に、編み地のウェールを40〜70ウェール/インチとなるよう設計することが好ましい。また、さらに重要なことは、弾性糸の編成時、通常の編込み長よりも短くして編成することであり、弾性糸と非弾性糸がプレーティング(添え糸編)で同組織の場合、弾性糸と非弾性糸との編込み長さ比を3.0以上、つまり非弾性糸のループ長(編込み長)よりも弾性糸のループ長を短くし、3.0倍以上に伸長して高張力で編込むのがよく、弾性糸と非弾性糸との組織が異なる場合も、弾性糸を高張力で編込むのがよい。さらに、弾性糸を被覆弾性糸として編成する場合は、被覆弾性糸を製造する際に、弾性糸を通常より多く3.0倍以上に伸長しながら被覆弾性糸を製造し、編機上でも高張力で編成すればループ数コントロールが容易に可能となり、伸長発熱温度が高い編み地が得られる。   In the knitted fabric of the present invention, in addition to the elastic yarn content, the knitted fabric filling rate, and the stress ratio, the product of the warp direction density (course / inch) of the knitted fabric and the weft direction density (wale / inch) of the knitted fabric. The number of loops of a certain knitted fabric is also important, and by keeping the number of loops within a specific range, the balance between the exothermic heat generation and the stress of the knitted fabric can be optimized. When the knitted fabric according to the present invention is a weft knitted fabric, the number of loops is preferably in the range of 3000 to 8000. Even if the elastic yarn content and the fineness ratio between the elastic yarn and the non-elastic yarn are within the specified range, the exothermic temperature may be low or the knitted fabric may be highly stressed. In other words, when the number of loops is less than 3000, the knitted fabric has a low degree of elongation, the elongation heat generation temperature is low, and when the number of loops is more than 8000, the knitted fabric has high stress and is difficult to move. In particular, when the number of loops is less than 3000, there is a high feeling of tension when the garment is used, and the air permeability of the knitted fabric may be increased. However, there is a lot of inflow of outside air because it is highly breathable, so it doesn't feel warm. From these, the number of loops is preferably 3000 to 8000, more preferably 3500 to 7500. The number of loops can be controlled by controlling the fineness ratio and the knitting machine gauge as well as the quality control during dyeing. To increase the number of loops, the fineness ratio must be reduced and the knitting machine gauge should be dense. It is easy to achieve by making the knitted fabric wider by a dyeing process and driving it. In particular, it is preferable to design the knitting wales to be 40 to 70 wales / inch. More importantly, when knitting the elastic yarn, it is knitted shorter than the normal knitting length. When the elastic yarn and the non-elastic yarn are plated (attached yarn knitting) and have the same structure, The knitting length ratio between the elastic yarn and the non-elastic yarn is 3.0 or more, that is, the loop length of the elastic yarn is shorter than the loop length (knitting length) of the non-elastic yarn, and the elastic yarn is stretched by 3.0 times or more. Therefore, the elastic yarn is preferably knitted with high tension even when the elastic yarn and the non-elastic yarn are different in structure. Furthermore, when the elastic yarn is knitted as a coated elastic yarn, when the coated elastic yarn is manufactured, the coated elastic yarn is manufactured while stretching the elastic yarn more than usual by 3.0 times or more, and it is high on the knitting machine. Knitting with tension makes it easy to control the number of loops, and a knitted fabric having a high elongation heat generation temperature can be obtained.

本発明による編み地が経編み地の場合は、ループ数が5000〜12000の範囲内が好ましい。弾性糸の含有量等が規定の範囲内であっても伸張発熱温度が低かったり、編地が高応力となったりすることがある。つまり、ループ数が5000未満では編み地の伸度が小さく、また、伸長発熱温度も低く、ループ数が12000より多い場合は編み地が高応力となり、動き難い衣服となる。特に、ループ数が5000未満の場合は、衣服とした際に突っ張り感が高いとともに、編み地の通気性も高くなることがあり、編み地の伸長発熱温度そのものが低いことに加え、伸長発熱しても通気性が高い事より外気の流入が多く暖かく感じない。これらより、ループ数は好ましくは5000〜12000とし、より好ましくは5500〜11500とすればよい。これらループ数のコントロールは、繊度比、編機のゲージとともに、染色加工時の性量コントロールにより可能で、ループ数を大きくするには、繊度比を小さくすること、編機ゲージを密にすること、染色加工で編み地を幅入れ、追い込み加工すること等により達成し易い。特に、編み地のウェールを50〜80ウェール/インチとなるよう設計するのが好ましい。また、さらに重要なことは、弾性糸の編成時、通常よりもランナーを短くして編成することである。但し、ランナーを短くし過ぎると糸切れ等のトラブルも発生するので、可能な範囲でランナーを短くすればよい。   When the knitted fabric according to the present invention is a warp knitted fabric, the number of loops is preferably in the range of 5000 to 12000. Even if the elastic yarn content is within a specified range, the exothermic temperature may be low, or the knitted fabric may be highly stressed. That is, if the number of loops is less than 5000, the knitted fabric has a low elongation, the elongation heat generation temperature is low, and if the number of loops is more than 12,000, the knitted fabric has a high stress and is difficult to move. In particular, when the number of loops is less than 5,000, there is a high feeling of tension when used as a garment, and the air permeability of the knitted fabric may be increased. However, there is a lot of inflow of outside air because it is highly breathable, so it doesn't feel warm. From these, the number of loops is preferably 5000 to 12000, more preferably 5500 to 11500. The number of loops can be controlled by controlling the fineness ratio and the knitting machine gauge as well as the quality control during dyeing. To increase the number of loops, the fineness ratio must be reduced and the knitting machine gauge should be dense. It is easy to achieve by putting the knitted fabric in the dyeing process and driving it. In particular, the knitted fabric is preferably designed to have a waling of 50 to 80 wales / inch. More importantly, the elastic yarn is knitted with a runner shorter than usual. However, if the runner is too short, troubles such as thread breakage may occur, so the runner should be shortened as much as possible.

本発明の編み地の製造において、染色加工時、通常よりも編み地を伸長気味に仕上げることが好ましく、目安としては生機とほぼ同密度で仕上げるようにする。これにより、弾性糸の含有量は少し低下するが編み地中の弾性糸は伸長されたままとなる結果、通常の編み地では、弾性糸原糸の繊度と、染色加工後の弾性糸の繊度とを比較すると、染色加工後の弾性糸の繊度は、原糸の繊度と同じかそれより数%細くなっているのに対し、本発明の編み地では、弾性糸原糸の繊度と染色加工後の繊度を比較した場合、染色加工後、10〜20%程度弾性糸が細くなり、伸長発熱温度の低下は少ないのに編地応力は低くすることが可能となっている。さらに、染色加工時に重要なことは、ヒートセット時、セット温度を高くする、セット時間を長くするなど、熱処理条件を強くして、編み地を伸長したままセットして、編地中の弾性糸をなるべく細くすることである。また、これらの編み地を伸長してセットする目安としては、初期長10.0cm、幅2.5cmにサンプリングした編み地の9.8N荷重下での編み地伸度を、最大でも150%以内となるよう設定することが好ましい。   In the production of the knitted fabric of the present invention, it is preferable that the knitted fabric is finished to be more stretched than usual at the time of dyeing, and as a guideline, it is finished with almost the same density as the raw machine. As a result, the content of the elastic yarn is slightly reduced, but the elastic yarn in the knitted fabric remains stretched. As a result, in a normal knitted fabric, the fineness of the elastic yarn raw yarn and the fineness of the elastic yarn after dyeing processing In comparison, the fineness of the elastic yarn after dyeing is the same as that of the original yarn or a few percent smaller than that of the original yarn. When the fineness is compared, the elastic yarn becomes thin about 10 to 20% after the dyeing process, and the knitted fabric stress can be lowered though the decrease in the elongation heat generation temperature is small. Furthermore, what is important during dyeing is that the elastic yarn in the knitted fabric is set while the knitted fabric is stretched by increasing the heat treatment conditions such as increasing the set temperature and lengthening the set time during heat setting. Is as thin as possible. In addition, as a guideline for setting these knitted fabrics by stretching, the knitted fabric elongation under a 9.8N load of a knitted fabric sampled to an initial length of 10.0 cm and a width of 2.5 cm is within 150% at the maximum. It is preferable to set so that.

本発明による編み地は、緯編み地の場合、パンスト編機等の筒編編機、小寸の釜径編機を含むシングル丸編機、ダブル丸編機等により製造可能であり、編組織については、天竺組織、スムース組織等のニットループ主体の編組織による編成が可能である。特に、天竺組織の場合は、32ゲージ以上の編機の使用が好ましく、また、スムース組織の場合は、弾性糸と非弾性糸とをプレーティング(添え糸編)して編成するのが好ましく、スムース組織では着用動作時に動き易いようにするために、弾性糸のプレーティングをすべてのコースに行うのではなく、1コース毎にプレーティングする等の方法により目的が達成可能である。より伸張発熱効果が高める為に、タックループ、ウェルトループ(ミスループとも称されるが、本願ではウェルトループと称す)を編地中にさらに配することは、これらのループが多くなるほど伸長発熱温度が高くなるため、好ましい。タックループ、ウェルトループの使用法については、弾性糸でタックループ又はウェルトループを形成するのが最も伸長発熱に効果的であるが、タックループ又はウェルトループは非弾性糸とし、該タックループ又はウェルトループの前後の少なくともいずれかのニットループを弾性糸で形成することも可能で、さらに、弾性糸でタックループ又はウェルトループを形成し、該タックループ又はウェルトループの前後の少なくともいずれかのニットループも弾性糸で形成すれば、高い伸長発熱温度が得られる。いずれも、弾性糸が伸ばされたループが形成され、伸長発熱温度を高くできて好ましいループ構造となる。また、これらタックループやウェルトループが多くなると伸度が低下し、伸びにくい編地となる傾向であるため、タックループ又はウェルトループをコース方向(編地経方向)に連続して組織するのは2コース以内とするのが好ましく、3コース以上連続すると編地伸度が極端に低下するため、低伸度を目的とする以外は避けるべきである。したがって、タックループ又はウェルトループの連続は2コース以内とするのが好ましいが、この場合、タックループとウェルトループの組み合わせでも2コース以内の連続とするのが好ましい。なお、タックループ又はウェルトループの連続は2コース以内とするが、斜め方向への連続は制限なく、また、ウェール方向(緯方向)への制限もなく編成可能な範囲での連続が可能である。さらに、タックループ又はウェルトループは、弾性糸の裸糸でも、非弾性糸とカバーリング、撚糸、噴射加工糸等による被覆弾性糸でも構わない。   In the case of a weft knitted fabric, the knitted fabric according to the present invention can be manufactured by a cylindrical knitting machine such as a pantyhose knitting machine, a single circular knitting machine including a small-sized shuttle knitting machine, a double circular knitting machine, etc. Can be knitted by a knitting loop-based knitting structure such as a tengu structure or a smooth structure. In particular, in the case of a tentacle structure, it is preferable to use a knitting machine having a gauge of 32 gauge or more. In the case of a smooth structure, it is preferable to knitted with an elastic yarn and an inelastic yarn plated (attached yarn knitting). In a smooth tissue, in order to make it easy to move during the wearing operation, the object can be achieved by a method such as plating for every course, instead of plating the elastic yarn for every course. In order to further enhance the stretching heat generation effect, the tuck loop and the welt loop (also referred to as a misloop but referred to as the welt loop in this application) are further arranged in the knitted fabric. Since it becomes high, it is preferable. Regarding the usage of the tuck loop or the welt loop, forming the tuck loop or the welt loop with the elastic yarn is most effective for the exothermic heat, but the tuck loop or the welt loop is an inelastic yarn, and the tuck loop or the welt loop is used. It is also possible to form at least one knit loop before and after the loop with an elastic yarn, and further form a tuck loop or a welt loop with the elastic yarn, and at least one knit loop before and after the tuck loop or the welt loop. If it is made of elastic yarn, a high exothermic temperature can be obtained. In either case, a loop in which the elastic yarn is stretched is formed, and the elongation heat generation temperature can be increased, and a preferable loop structure is obtained. In addition, when these tuck loops and welt loops increase, the elongation tends to decrease and the knitted fabric tends to be difficult to stretch. Therefore, the tuck loop or the welt loop is continuously organized in the course direction (knitting warp direction). Within 2 courses is preferable, and when 3 or more courses are continued, the knitted fabric elongation is extremely lowered, and should be avoided except for the purpose of low elongation. Therefore, it is preferable that the tuck loop or the welt loop be continuous within two courses, but in this case, the combination of the tuck loop and the welt loop is preferably continuous within two courses. The tuck loop or the welt loop is continuous within two courses, but the continuous in the diagonal direction is not limited, and can be continued in the range where knitting is possible without limitation in the wale direction (weft direction). . Further, the tack loop or the welt loop may be a bare elastic yarn, or a covered elastic yarn such as a non-elastic yarn and a cover ring, a twisted yarn, an injection processed yarn or the like.

また、タックループ又はウェルトループを編地中に組織することが好ましいが、これらタックループ又はウェルトループは、単独又は組み合わさって組織されていてもよく、組み合わせの例としてウェール方向にニットループとタックループ又はウェルトループとを交互に又は任意な繰返し単位で配置した組織、あるいは、コース方向に、ニットループとタックループ又はウェルトループとを交互に又は任意な繰返し単位で配置した組織が使用できる。   In addition, it is preferable that the tuck loop or the welt loop is organized in the knitted fabric, but these tuck loops or the welt loop may be organized singly or in combination, and as an example of the combination, the knit loop and the tuck are arranged in the wale direction. A tissue in which loops or welt loops are arranged alternately or in arbitrary repeating units, or a tissue in which knit loops and tack loops or welt loops are arranged alternately or in arbitrary repeating units in the course direction can be used.

ニットループと、タックループ及び/又はウェルトループとの編み地中の比率については、少なくとも編み地片面のタックループ及び/又はウェルトループ数が編み地表面の全ループ数の20〜60%となるよう調整する。タックループ及び/又はウェルトループが20%未満では伸長発熱効果が小さく、発熱し難い編み地となり、60%より多いと伸長発熱温度は高いが伸びにくい編み地となり、衣服として着用時に動き難い製品となり好ましくない。従い、タックループ及び/又はウェルトループの比率は20〜60%とし、好ましくは25〜50%とすればよい。なお、編み地中のタックループ及び/又はウェルトループの割合は、編組織の一完全組織内のニットループ、タックループ、及びウェルトループのそれぞれのループ数より計算する。無論、編み地中にニットループのみの部分が大きな面積を占めていて、タックループやウェルトループが組み込まれている部分が縞状、あるいは島状に存在している設計も可能であるが、この場合、ニットループの部分の伸張発熱温度は低いので、膝や肘部など伸縮する部位にタックループやウェルトループが組織されている部分となるよう製品で配置すればよい。   Regarding the ratio of the knit loop to the tuck loop and / or the welt loop in the knitted fabric, at least the number of tuck loops and / or the welt loops on one side of the knitted fabric is 20 to 60% of the total number of loops on the surface of the knitted fabric. adjust. If the tuck loop and / or the welt loop is less than 20%, the stretch heat generation effect is small and the knitted fabric hardly generates heat. If it exceeds 60%, the stretch heat generation temperature is high but the stretch knitted fabric is difficult to stretch. It is not preferable. Accordingly, the ratio of the tack loop and / or the welt loop is 20 to 60%, preferably 25 to 50%. In addition, the ratio of the tack loop and / or the welt loop in the knitted fabric is calculated from the number of loops of the knit loop, the tack loop, and the welt loop in one complete knitted structure. Of course, it is possible to design the knitted fabric with only the knit loop occupying a large area and the tuck loop or the welt loop being incorporated in the stripe or island shape. In this case, since the exothermic temperature at the knit loop portion is low, the knit loop portion may be arranged as a product so that a tuck loop or a welt loop is formed in a stretchable part such as a knee or an elbow.

なお、これらタックループ及び/又はウェルトループの配置は、ダブル丸編機の場合、シリンダー又はダイアルの少なくとも一方の組織内で配置されていることが重要で、シリンダーとダイアルは、それぞれ独立しているとみなし、それぞれの側に組織されているループ形状で判断する。また、タックループ及び/又はウェルトループは、弾性糸と非弾性糸両方で形成されているのが好ましいが、弾性糸のみ又は非弾性糸のみで形成されていてもよい。   In the case of a double circular knitting machine, it is important that these tack loops and / or welt loops are arranged in at least one of the structures of the cylinder and the dial, and the cylinder and the dial are independent of each other. Judging by the loop shape organized on each side. In addition, the tack loop and / or the welt loop is preferably formed of both an elastic yarn and an inelastic yarn, but may be formed of only an elastic yarn or only an inelastic yarn.

本発明による編み地が経編み地の場合、通常のシングルトリコット編機、ダブルトリコット編機、シングルラッセル編機、ダブルラッセル編機により編成可能であり、編組織については、通常の組織により編成が可能であるが、挿入組織の連続は2コース以下が好ましい。特に、シングルトリコット編機、シングルラッセル編機による弾性糸の組織において、開き目によるニットループを形成するのが好ましく、これにより、衣服として着用動作時に動き易くすることが可能となる。開き目組織の例として、01/21、01/32、01/12/32等、ニットループ全てが開き目であることが好ましい。なお、これらの開き目は、弾性糸の裸糸でも、非弾性糸とカバーリング、撚糸、噴射加工糸等による被覆弾性糸でも構わない。なお、弾性糸は開き目であることが好ましいが、非弾性糸については、開き目、閉じ目、開き目と閉じ目の組み合わせ等を、任意に選択できる。   When the knitted fabric according to the present invention is a warp knitted fabric, it can be knitted by a normal single tricot knitting machine, a double tricot knitting machine, a single raschel knitting machine, or a double raschel knitting machine. Although it is possible, the continuous insertion tissue is preferably 2 courses or less. In particular, it is preferable to form a knit loop with an opening in an elastic yarn structure by a single tricot knitting machine or a single raschel knitting machine, and this makes it possible to move easily as a garment during a wearing operation. As examples of the opening structure, it is preferable that all knit loops such as 01/21, 01/32, 01/12/32, and the like have an opening. These open stitches may be bare elastic yarns or covered elastic yarns such as non-elastic yarns and coverings, twisted yarns, jetted yarns, and the like. In addition, although it is preferable that an elastic thread is an opening, about an inelastic thread, an opening, a closing eye, a combination of an opening and a closing, etc. can be selected arbitrarily.

本発明の編み地は、編組織や糸使いを変更したり、樹脂プリント等を施したりすることにより、点状、直線状、曲線状等の部分的にパワーが異なる高パワー部と低パワー部とを混在させてもよい。この場合、編み地中の一部分でも本性能を満足すればよい。例えば、膝など伸長発熱効果が欲しい部分のみ高伸長発熱編地を配し、膝回り等は高パワーの定伸長編地を配置することも可能で、この場合、膝の動きで暖かくなり、また、低伸長部で膝関節の保護等を狙った製品とすることが可能となる。   The knitted fabric of the present invention has a high power portion and a low power portion that are partially different in power, such as a dotted shape, a straight shape, and a curved shape, by changing the knitting structure and yarn usage, or by performing resin printing or the like. May be mixed. In this case, it is only necessary to satisfy this performance even in a part of the knitted fabric. For example, it is possible to place a high-strength exothermic knitted fabric only on the part that wants an exothermic heat effect, such as the knee, and a high-power constant stretch knitted fabric around the knee, etc. It becomes possible to make a product aimed at protecting the knee joint, etc., in the low extension part.

本発明の編み地に使用する弾性糸は、ポリウレタン系又はポリエーテルエステル系の弾性糸であることができ、例えば、ポリウレタン系弾性糸としては、乾式紡糸又は溶融紡糸したものが使用でき、ポリマーや紡糸方法は特に限定されない。弾性糸の破断伸度は400%〜1000%程度であり、かつ、伸縮性に優れ、染色加工時のプレセット工程の通常処理温度180℃近辺で伸縮性を損なわないことが好ましい。また、弾性糸としては、特殊ポリマーや粉体添加により、高セット性、抗菌性、吸湿、吸水性等の機能性を付与した弾性糸も使用可能である。弾性糸の繊度に関しては、20〜110dtex程度の繊維の使用が可能で、編み地製造が容易で伸長発熱温度も高いという観点から、30〜80dtex程度の弾性繊維の使用が好ましい。また、弾性糸に非弾性糸を巻きつけたカバーリング糸、非弾性糸と弾性糸とを撚糸した糸、及び非弾性糸と弾性糸とを空気噴射等により混繊した混繊糸等、被覆弾性糸の使用も可能である。   The elastic yarn used for the knitted fabric of the present invention can be a polyurethane-based or polyether ester-based elastic yarn. For example, as the polyurethane-based elastic yarn, those obtained by dry spinning or melt spinning can be used. The spinning method is not particularly limited. The breaking elongation of the elastic yarn is about 400% to 1000%, is excellent in stretchability, and it is preferable that the stretchability is not impaired near the normal processing temperature of 180 ° C. in the presetting process during dyeing. As the elastic yarn, an elastic yarn imparted with functions such as high setting property, antibacterial property, moisture absorption and water absorption by addition of a special polymer or powder can be used. Regarding the fineness of the elastic yarn, it is possible to use a fiber of about 20 to 110 dtex, and from the viewpoint of easy knitted fabric production and a high exothermic temperature, it is preferable to use an elastic fiber of about 30 to 80 dtex. Also, covering yarn, covering yarn in which inelastic yarn is wound around elastic yarn, yarn in which inelastic yarn and elastic yarn are twisted, and mixed yarn in which inelastic yarn and elastic yarn are mixed by air injection etc. The use of elastic yarn is also possible.

さらに本発明の編み地は、弾性糸に無機物質を含有することが可能で、含有する無機物質の性能を加味した編み地とすることができ、例えば、酸化チタンを含有させると、編み地の発熱を酸化チタンに蓄え、遠赤外線効果による保温性を付与することができる。無機物質の含有法としては、弾性糸の紡糸原液に無機物質を含有させて紡糸する方法が最も簡単である。本発明でいう無機物質とは、酸化チタン等のセラミックス、カーボン、カーボンブラック等の無機物単体及び/又は無機化合物をいい、弾性糸の紡糸の障害とならない様、微粉末状が好ましい。これら無機物質は弾性糸に1〜10重量%含有されていることが好ましく、無機物質を含有することにより、編地の発熱時保温効果をより効果的に発揮することが可能となる。なお、無機物質は少ないと保温効果が小さく、多すぎると紡糸時や伸長時に糸切れすることがあるため、1〜10重量%の含有が好ましく、より好ましくは2〜5重量%の含有である。   Furthermore, the knitted fabric of the present invention can contain an inorganic substance in the elastic yarn, and can be a knitted fabric that takes into account the performance of the contained inorganic substance. For example, when titanium oxide is contained, Heat generation can be stored in titanium oxide, and heat retention by the far-infrared effect can be imparted. As the method of containing an inorganic substance, the simplest method is to add an inorganic substance to a spinning dope for elastic yarn and perform spinning. The term “inorganic substance” as used herein refers to ceramics such as titanium oxide, inorganic substances such as carbon and carbon black, and / or inorganic compounds, and is preferably finely powdered so as not to hinder spinning of elastic yarns. These inorganic substances are preferably contained in the elastic yarn in an amount of 1 to 10% by weight. By containing the inorganic substance, it becomes possible to more effectively exhibit the heat retention effect during heat generation of the knitted fabric. If the inorganic substance is small, the heat retention effect is small, and if it is too large, the yarn may break during spinning or stretching, so the content is preferably 1 to 10% by weight, more preferably 2 to 5% by weight. .

本発明の編み地に用いられる弾性糸は、ポリウレタン系弾性糸やポリエーテルエステル系弾性糸が挙げられるが、伸長発熱温度を上げるには、弾性糸の分子量を上げる方法がある。他の方法としては、応力比を小さくした弾性糸の使用が好ましく、例えば、特開2001−140127号公報に示される、第1級アミン又は第2級アミンのいずれかの1官能性アミン、水酸基、及び第3級窒素又は複素環状窒素から選ばれる少なくとも1種を含む窒素含有化合物と有機ジイソシアナートとが反応して得られる、1分子あたりの平均ウレア結合単位数が4〜40個であるウレタンウレア化合物;特許第4343446号公報に示される、第1級アミン及び第2級アミンのうちの少なくとも1種から選ばれる2官能性アミノ基、第3級窒素及び複素環状窒素のうちの少なくとも1種から選ばれる窒素含有基を含む窒素含有化合物と、有機ジイソシアナート、モノ又はジアルキルモノアミン、アルキルモノアルコール、及び有機モノイソシアナートからなる群から選ばれる少なくとも1種の化合物とを反応させて得られるウレア化合物;特開平7−316922号公報に示される、ポリアクロニトリル系ポリマー、低分子ジオール、及びポリマージオールの混合物と、有機ジイソシアナートとの反応で得られる末端水酸基構造であるポリウレタン;あるいはスチレン−無水マレイン酸共重合体等を添加して紡糸する方法がある。上記末端水酸基構造であるポリウレタンとしては、炭素原子数2〜10の直鎖状又は分岐状アルキレン基若しくは二価の脂環式炭化水素の両末端に水酸基を有する低分子ジオール及び数平均分子量400〜3000の高分子ジオールの混合物(モル比1〜99)と有機ジイソシアナートとの反応物であって、末端が水酸基でありウレタン基濃度が3ミリ当量/g以上である数平均分子量10000〜40000のポリウレタン重合体であることが好ましい。これらを単独で又は2種以上混合して弾性糸中に添加すればよいが、添加量が少ないと伸長発熱温度効果が低く、逆に添加量が多いと、編地伸長回復性が低下し、着用、洗濯により型崩れが生じやすくなるため、添加量は、弾性糸重量に対して2.0〜15.0%、好ましくは2.5〜8.0%とする。   Examples of the elastic yarn used in the knitted fabric of the present invention include polyurethane-based elastic yarn and polyether ester-based elastic yarn. To increase the elongation heat generation temperature, there is a method of increasing the molecular weight of the elastic yarn. As another method, it is preferable to use an elastic yarn having a reduced stress ratio. For example, as shown in JP 2001-140127 A, a monofunctional amine or a hydroxyl group of either a primary amine or a secondary amine is used. And an average number of urea bond units per molecule obtained by reacting a nitrogen-containing compound containing at least one selected from tertiary nitrogen and heterocyclic nitrogen with an organic diisocyanate is 4 to 40 Urethane urea compound; as shown in Japanese Patent No. 4343446, at least one of a bifunctional amino group selected from at least one of a primary amine and a secondary amine, a tertiary nitrogen and a heterocyclic nitrogen Nitrogen-containing compounds containing nitrogen-containing groups selected from species, organic diisocyanates, mono- or dialkyl monoamines, alkyl monoalcohols, and organic A urea compound obtained by reacting with at least one compound selected from the group consisting of noisocyanates; a mixture of a polyacrylonitrile-based polymer, a low molecular diol, and a polymer diol disclosed in JP-A-7-316922 And a polyurethane having a terminal hydroxyl group structure obtained by reaction with an organic diisocyanate; or a method of spinning by adding a styrene-maleic anhydride copolymer or the like. Examples of the polyurethane having a terminal hydroxyl group structure include a low molecular diol having a hydroxyl group at both ends of a linear or branched alkylene group having 2 to 10 carbon atoms or a divalent alicyclic hydrocarbon, and a number average molecular weight of 400 to 400. A number average molecular weight of 10,000 to 40,000, which is a reaction product of a mixture of 3000 high molecular diols (molar ratio 1 to 99) and an organic diisocyanate, having a terminal hydroxyl group and a urethane group concentration of 3 meq / g or more. The polyurethane polymer is preferred. These may be added to the elastic yarn alone or in combination of two or more, but if the addition amount is small, the elongation exothermic temperature effect is low, and conversely, if the addition amount is large, the knitted fabric stretch recovery is reduced, Since it becomes easy to lose shape due to wearing and washing, the addition amount is 2.0 to 15.0%, preferably 2.5 to 8.0%, based on the weight of the elastic yarn.

本発明に用いる非弾性糸としては、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート等のポリエステル系繊維、ポリアミド系繊維、並びにポリプロピレン等のポリオレフィン系繊維、さらに、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、これらのブライト糸、セミダル糸、フルダル糸等を任意に使用でき、繊維の断面形状についても、丸型、楕円型、W型、繭型、中空糸等任意の断面形状の繊維が使用可能であり、繊維の形態についても特に限定されず、原糸、仮撚等の捲縮加工糸が使用でき、非弾性糸の太さは20〜110dtex、好ましくは、30〜90dtexの非弾性糸の使用が好適である。さらに、長繊維でも紡績糸でもよく、また、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の使用も可能である。さらには、繊維自体での混合ではなく、編機上での2種以上の繊維の混合も無論可能である。   Examples of inelastic yarns used in the present invention include polyester fibers such as polyethylene terephthalate and polytrimethylene terephthalate, polyamide fibers, and polyolefin fibers such as polypropylene, and cellulose fibers such as cupra, rayon, cotton, and bamboo fibers.

Also, these bright yarns, semi-dal yarns, full dull yarns, etc. can be used arbitrarily, and the fibers can have any cross-sectional shape such as round, elliptical, W-shaped, saddle-shaped, hollow fiber, etc. The shape of the fiber is not particularly limited, and crimped yarn such as raw yarn and false twist can be used. The thickness of the inelastic yarn is 20 to 110 dtex, preferably 30 to 90 dtex of the inelastic yarn. Use is preferred. Further, it may be a long fiber or a spun yarn, and a composite yarn obtained by mixing two or more kinds of fibers by twisting, covering, air blending, or the like can be used. Furthermore, it is of course possible to mix two or more types of fibers on the knitting machine instead of mixing the fibers themselves.

本発明に用いる非弾性糸、特に、ポリエステル系繊維、ポリアミド系繊維、セルロース系繊維の場合には、無機物質を0.3〜5重量%含有していることが好ましい。無機物質を含有することにより、弾性編地の発熱時、保温効果をより効果的に発揮することが可能となる。なお、無機物質は、少ないと保温効果が小さく、多すぎると紡糸時や伸長時に糸切れすることがあるため、0.5〜5重量%の含有がより好ましく、さらに好ましくは0.4〜3重量%の含有である。   In the case of inelastic yarns used in the present invention, particularly polyester fibers, polyamide fibers, and cellulose fibers, it is preferable to contain 0.3 to 5% by weight of an inorganic substance. By containing the inorganic substance, it is possible to more effectively exhibit the heat retaining effect when the elastic knitted fabric generates heat. If the inorganic substance is small, the heat retention effect is small, and if it is too large, yarn breakage may occur at the time of spinning or stretching. Therefore, the content is more preferably 0.5 to 5% by weight, and further preferably 0.4 to 3%. It is contained by weight%.

Is possible. Furthermore, it is possible to make it difficult to release the heat generated by using spun yarn or raising, and it is possible to enhance the heat retaining effect.

(3) Elastic Yarn Content The elastic yarn content (g / m 2 ) in the knitted fabric is obtained by the following method and rounded off to one decimal place.
The inelastic yarn in the knitted fabric is removed by dissolution or the like, and the weight of only the elastic yarn is measured and converted to the weight per unit area. If it is difficult to remove the non-elastic yarn, the elastic yarn is removed from the knitted fabric after the weight measurement by dissolving, etc., and the weight of only the non-elastic yarn is measured. To do.
(4) Knitted fabric filling rate It calculated by the following formula.
Filling rate (%) = (M / L) ÷ (H1 × K1 + H2 × K2 + ·· + Hn × Kn) × 100
In the above equation, L is a thickness (cm) at a load of 6 g / cm 2 measured with a KES compression tester, M is a weight (g / cm 2 ) per unit area, and H1, H2,. The specific gravity of each of the fibers 1, 2, ·· n contained in the knitted fabric, and K1, K2, ··· Kn are the mixing ratio of the fibers 1, 2, ·· n contained in the knitted fabric. The weight and thickness are numerical values under an environment of 20 ° C. and 65% RH. For the specific gravity of the fiber, the specific gravity of the fiber according to the Fiber Handbook (Maruzen) is used, and for the fiber having a wide specific gravity, the intermediate value is used. As for the mixing ratio, for example, when the mixing ratio is 80%, a numerical value of 0.80 is used. The filling rate is expressed as an integer by rounding off the first decimal place of the obtained numerical value.
