ポリウレタン弾性糸を使用した弾性ファブリンりは、一
般にインナーウェア、スポーツウェア等の伸縮性を必要
とする分野に多用されている。(Prior Art) Elastic fabrication using polyurethane elastic yarn is generally widely used in fields that require elasticity, such as innerwear and sportswear.
ここで多く用いられるのは、−ａにはポリエーテル系の
ポリウレタン弾性糸であり、それは優れた耐加水分解性
と耐熱性、それにハイパワーであることが主な理由であ
る。Polyether-based polyurethane elastic yarn is often used for -a, mainly because it has excellent hydrolysis resistance, heat resistance, and high power.
また、ポリエステル系のポリウレタン弾性糸は、耐塩素
性の要求される水着等の分野に多用される。Furthermore, polyester-based polyurethane elastic yarns are often used in fields such as swimwear that require chlorine resistance.
近年、弾性ファブリツタに対する要求が高度化しつつあ
り、単純なパワーの強さではユーザーの満足が得られな
い状況になりつつある。In recent years, requirements for elastic fabricators have become more sophisticated, and it is becoming increasingly difficult for users to be satisfied with simple power.
すなわち： ■ 着脱のしやすさ； ■ 着用時の適度な身体保持性； ■ 着用時の運動機能性と低被服圧； が、従来よりもまして強く要求されてきている。Namely: ■ Ease of putting on and taking off; ■ Appropriate body retention when worn; ■Motor functionality and low pressure when worn; However, there is a stronger demand than ever before.
着脱のしやすさとは、換言すれば大きな余裕伸度のこと
をいい、身体保持性とは、着用時にある力で身体を希望

、人間の人体運動のし易さのことで、更には人体運動に
対する動作適応性を云い、被服圧とは、皮膚の伸縮によ

とを言う。In other words, ease of putting on and taking off refers to a large amount of extra stretch, body retention refers to the ability to hold the body in a desired form with a certain force when worn, and athletic functionality refers to It refers to the ease with which the human body moves, and further refers to the adaptability of movement to human body movements. Covering pressure refers to the contact pressure that causes elastic deformation of the covering due to expansion and contraction of the skin and presses the body.
このような物性は、現在一般に多用されているポリエー
テル系のポリウレタン弾性糸のように、比較的ハイパワ
ーで低伸度のものから得られるファプリツタでは、通常
の方法では実現しにくかった。Such physical properties have been difficult to achieve using normal methods with fabrics that are obtained from materials with relatively high power and low elongation, such as the polyether-based polyurethane elastic yarns that are commonly used today.

ない。In particular, in order to obtain the new required physical properties of (1) and (3) above with conventional polyurethane elastic yarns, techniques such as using multiple types of polyurethane elastic yarns and adopting special weaving methods have been considered. However, the resulting fabric is extremely expensive, has poor productivity, and can only be used for special purposes.

対する抵抗性のなさが致命的な欠点となり、実用上大き
な制限があった。In addition, since polyester-based polyurethane elastic yarns can be obtained relatively easily with high elongation and low power, various tests have been conducted to obtain similar fiber properties. In addition to the poor hydrolysis resistance and heat resistance peculiar to yarn, the lack of resistance to mold was a fatal drawback, and there were major limitations in practical use.

という大きな特徴を同時に発揮できるものである。It is possible to simultaneously demonstrate these major characteristics.
本発明のファブリックは、このような物性的特徴を有す
るから、従来品では実現出来なかった着用時の数々の問
題点が解決される。Since the fabric of the present invention has such physical characteristics, it solves a number of problems when worn that could not be achieved with conventional products.
すなわち、上記の（１）、（２）からは着脱の容易性が
得られ、（２）、（３）、（４）からは一定のパワーで
体をサポートした後は体の運動による伸縮に対し必要以
上の圧迫感を与えないこと、すなわち着用時の運動機能
性が良く被服圧が低いことが得られ、（３）、（４）か
らは適度な身体保持性が得られる。In other words, from (1) and (2) above, ease of attachment and detachment is obtained, and from (2), (3), and (4), after supporting the body with a certain amount of power, it is possible to expand and contract due to body movement. On the other hand, it does not give a feeling of pressure more than necessary, that is, it provides good exercise functionality when worn, and the pressure on the garment is low, and from (3) and (4), appropriate body retention properties are obtained.
特に、運動機能性及び被服圧は、着用感に対して極めて
大きな影響を与え、大きな運動するスポーツウェアでは
最大のポイントとなる。In particular, athletic functionality and clothing pressure have an extremely large effect on the feeling of wearing the garment, and are the most important factors in sportswear for large-scale exercise.
着心地の重要なファクターである運動機能性は、以下の
ようにして評価される。Athletic functionality, which is an important factor in comfort, is evaluated as follows.
ファプリツタを伸張していった時の応力変化をグラフに
表したものを、５ＴＲＥＳＳ−３ＴＲＡ［Ｎカーブ（応
力−歪曲線、以下ＳＳカーブと略称する）と言い、この
ＳＳカーブの、実用伸度領域での伸度の増加に対する応
力の増加率を運動機能性の指標と定義する。The graph representing the stress change when the fiber is stretched is called the 5TRESS-3TRA [N curve (stress-strain curve, hereinafter abbreviated as SS curve), and the practical elongation range of this SS curve is The rate of increase in stress with respect to increase in elongation is defined as an index of motor functionality.
すなわち、第１図において、 −Ａ Ｘ＝ を運動機能性指数とする。That is, in Figure 1, -A X = is a motor function index.
ここで、Ａ、Ｂは生地をある実用伸度に伸張させた時の
応力とする。Here, A and B are the stresses when the fabric is stretched to a certain practical elongation.
Ｘは、ある伸度からある伸度まで生地を伸張した時の応
力の増加率を示すことになる。X indicates the rate of increase in stress when the fabric is stretched from a certain elongation to a certain elongation.
この運動機能性指数が小さいほど、体の動きに対して応
力の変化が少ないことを示し、「動きやすい、つっばら
ない」ファブリックであると言え次に被服圧は、二軸伸
長測定により、実際の皮膚伸びにみられるタテ・ヨコ同
時伸びを測定し、被服圧を求めることができる。The smaller the motor function index, the smaller the change in stress due to body movements, indicating that the fabric is "easy to move in and not stiff."Next, the clothing pressure was determined by biaxial elongation measurement. The clothing pressure can be determined by measuring the simultaneous vertical and horizontal elongation of the skin.
理論式より求める被服圧測定方法（ゆとり・ずれのない
場合）は；
で求められる。The method of measuring the wearing pressure using the theoretical formula (if there is no slack or deviation) is determined by:
二軸引張試験機による引張試験は、第２−１図に示す測
定機を用いる方法で測定するし、得られた代表的データ
ーを第２−２図に示した。The tensile test using a biaxial tensile tester is performed using the measuring device shown in Figure 2-1, and the typical data obtained is shown in Figure 2-2.
被服圧は被服圧針によっても測定される。実際の人体は
複曲面であるから、被服圧は布の水平・垂直両方向の張
力と、その点における人体の曲率に関係する。The dressing pressure is also measured by a dressing pressure needle. Since the actual human body has a multicurved surface, the covering pressure is related to both the horizontal and vertical tension of the cloth and the curvature of the human body at that point.
更に、もう１つのファクターである身体保持性は、第３
図において、Ｓ−Ｓカーブのある実用伸度における復時
の応力を、往時の応力で除した値で表す。Furthermore, another factor, body retention, is the third
In the figure, the stress at the time of return at a certain practical elongation of the SS curve is expressed as a value divided by the stress at the time.
Ｓ＝
に
こで、Ｃはある実用伸度に生地を伸張回復させたときの
往時の応力、Ｄは復時の応力を示す。S = Nico, C indicates the stress at the time of stretching and recovery of the fabric to a certain practical elongation, and D indicates the stress at the time of recovery.
また、着脱容易性は、ファブリックをある幅に裁断した
短冊状のものを、実際に手で伸張して得られる限界伸度
に近い２．２５ｋｇ時の伸度で表す。Moreover, the ease of putting on and taking off is expressed by the elongation at 2.25 kg, which is close to the limit elongation obtained by actually stretching a strip of fabric cut to a certain width by hand.

These mating fibers may be used as they are, or may be used in the form of so-called processed yarn, which has undergone processing such as crimping to change the shape and function.
また、本発明のポリウレタン弾性糸は、ペアの状態で使
用してもよいし、他の繊維でカバー、または合撚された
、いわゆる弾性加工糸の状態で使用してもよい。Further, the polyurethane elastic yarn of the present invention may be used in a pair, or may be used in a so-called elastic textured yarn covered with other fibers or twisted together.
特に、弾性加工糸とする際には、本発明のポリウレタン
の弾性糸の著しく大きな破断伸度の影響でカバリング時
のポリウレタン弾性糸のドラフトを大きく設定できるた
め、高価なポリウレタン弾性糸の混率を低く抑えること
ができ、コストの点から好ましい。In particular, when making an elastic textured yarn, the draft of the polyurethane elastic yarn during covering can be set to a large value due to the extremely high breaking elongation of the polyurethane elastic yarn of the present invention, so the blending ratio of the expensive polyurethane elastic yarn can be reduced. This is preferable from the viewpoint of cost.
