Description
本発明は編地に関する。より詳細には、本発明は、吸湿性、着用時の快適性に優れ、運動等により発汗した際にも、その汗によるベタツキ感や濡れ感を感じにくく、肌触りや外観も良好なインナーウエア、スポーツウエア、寝具等に好適に用いられる編地に関する。 The present invention relates to a knitted fabric. More specifically, the present invention is excellent in hygroscopicity, comfort at the time of wearing, and even when sweating due to exercise etc., it is difficult to feel a sticky feeling or wet feeling due to the sweat, and the innerwear has a good touch and appearance, The present invention relates to a knitted fabric suitably used for sportswear, bedding and the like.
綿、キュプラなどのセルロース系素材は吸湿性、吸水性に優れ、衣服として用いた場合、汗をかいていない状態（不感蒸泄時）や少量の発汗時には非常に快適である。しかし、夏季や運動時に発汗量が概ね１００ｇ／ｍ２を超える時には、セルロース系素材が吸った汗を保持しやすいため、いわゆるベタツキ感や運動後の冷え感を生じやすい。特に、汗の量が概ね２００ｇ／ｍ２を超える時には、このベタツキ感や冷え感は深刻で、非常に不快となる。 Cellulose-based materials such as cotton and cupra are excellent in hygroscopicity and water absorption, and when used as clothes, they are very comfortable when not sweating (insensitive vaporization) or when sweating a small amount. However, when the amount of perspiration exceeds approximately 100 g / m 2 during summer or exercise, the cellulosic material tends to retain the sweat sucked, so that a so-called sticky feeling or a feeling of cooling after exercise is likely to occur. In particular, when the amount of sweat exceeds approximately 200 g / m 2 , this feeling of stickiness and feeling of cooling is serious and very uncomfortable.
これらの不快感を防止するための方法として、汗を衣服の肌側から表側に移行させ、肌側に水分を残さないことを狙い、種々の布帛の検討が進められている。その多くは肌側に疎水性繊維を用いることによるものであり、使用する糸の単糸繊度や断面形状を編地表側と裏側で異ならせた布帛などが各種提案されている。 As a method for preventing such discomfort, various fabrics have been studied with the aim of transferring sweat from the skin side to the front side of clothing and leaving no moisture on the skin side. Most of them are due to the use of hydrophobic fibers on the skin side, and various proposals have been made on fabrics in which the single yarn fineness and cross-sectional shape of the yarns used are different on the knitted fabric front side and back side.
例えば、以下の特許文献１には、編地表側に綿のような吸水能力に優れた繊維、編地裏側にポリエステルフィラメントのような吸水能力の劣る繊維を使用することで編地裏側に水分を残さない構造とし、ベタツキ感や冷え感を抑制する編地が提案されている。特許文献１では、べたつき低減の効果を発現できるが、合成繊維フィラメントが肌側に配置されているため、肌触りが良いとはいえず、特に汗をかいていない状況もしくは汗の量が少ない状況では不快である。
For example, in the following
以下の特許文献２と３には、編地裏（肌）側に親水性繊維を含んだ編地も開示されている。特許文献２では、編地裏（肌）側に親水性繊維、編地裏側に疎水性繊維を使用し、編地裏（肌）側の密度を編地表側の密度よりも大きくし、編地裏（肌）側に凹凸を付与することで、肌のサラサラ感を有する編地が開示されている。しかし、該編地は、高密度でかつ親水性繊維の混率が２５〜７５％と非常に高いため、肌側に保水され、凹凸があってもベタツキ感は大きく、衣料用途としての肌ＤＲＹ性は不十分である。一方、特許文献３では、裏（肌）側に吸湿繊維が配された2層構造編地が開示されている。しかし、該２層構造編地は、裏側に紡績糸が使用されているために皮膚摩擦抵抗が大きく、皮膚刺激や肌触りの点で問題があった。 Patent Documents 2 and 3 below also disclose knitted fabrics containing hydrophilic fibers on the knitted fabric back (skin) side. In Patent Document 2, hydrophilic fibers are used on the back side (skin) side of the knitted fabric, hydrophobic fibers are used on the back side of the knitted fabric, the density on the back side of the knitted fabric (skin) side is made larger than the density on the front side of the knitted fabric, A knitted fabric having a smooth feeling on the skin by providing irregularities on the back (skin) side is disclosed. However, since the knitted fabric has a high density and a high mixing ratio of hydrophilic fibers of 25 to 75%, the water is retained on the skin side, and even if there are irregularities, the feeling of stickiness is large, and the skin DRY property as a garment application Is insufficient. On the other hand, Patent Document 3 discloses a two-layer structure knitted fabric in which moisture absorption fibers are arranged on the back (skin) side. However, the double-layered knitted fabric has a problem in terms of skin irritation and touch because the spun yarn is used on the back side and the skin friction resistance is large.
このように、肌触りがよく、不感蒸泄時や少量の発汗時にムレがなく快適で、かつ、発汗した際にもベタツキ感や冷え感を抑制する布帛は現状では見当たらない。 As described above, there is no fabric that has a good touch, is comfortable with no stuffiness at the time of insensitive steaming or a small amount of sweating, and suppresses the feeling of stickiness or cooling even when sweating.
本発明が解決しようとする課題は、不感蒸泄時や少量の発汗時にムレがなく快適で、かつ、運動等により発汗した際にも、その汗によるベタツキ感や濡れ感を感じにくく、肌触りも良好な編地を提供することである。 The problem to be solved by the present invention is that there is no stuffiness at the time of insensitive steaming or a small amount of sweating, and even when sweating due to exercise etc., it is difficult to feel the sticky feeling and wet feeling due to the sweat, and the touch is also It is to provide a good knitted fabric.
本発明者は、上記課題を解決すべく鋭意研究し、実験を重ねた結果、肌に接触する編地裏面にセルロース系長繊維を含み、特定の厚みと凹凸構造をもつことで上記課題を解決しうることを見出し、本発明を完成するに至った。
すなわち、本発明は以下の通りのものである。
［１］セルロース系長繊維が５〜２５％含まれ、かつ、その厚みが０．５〜１．２ｍｍである編地であって、該編地の少なくとも一方の表面にはセルロース系長繊維が配されず、該編地の他方の表面に、又は該編地の他方の表面及び該編地の中間層にセルロース系長繊維が配された構造を有し、該セルロース系長繊維が配された面の凸部と凹部の高さの差が０．１５〜０．５０ｍｍであり、かつ、該セルロース系長繊維が配された面の２００ｇ／ｍ２水分付与時の接触冷感性が２００〜３３０Ｗ／ｍ２・℃であることを特徴とする前記編地。
As a result of earnestly researching and solving the above-mentioned problems, the present inventor has solved the above problems by including cellulose-based long fibers on the back of the knitted fabric in contact with the skin and having a specific thickness and uneven structure. As a result, the present invention has been completed.
That is, the present invention is as follows.
[1] A knitted fabric containing 5 to 25% of cellulosic long fibers and having a thickness of 0.5 to 1.2 mm, and cellulosic long fibers are formed on at least one surface of the knitted fabric. A cellulosic long fiber is arranged on the other surface of the knitted fabric or on the other surface of the knitted fabric and an intermediate layer of the knitted fabric. The difference in height between the convex part and the concave part on the surface is 0.15 to 0.50 mm, and the contact cooling sensation at the time of applying 200 g / m 2 moisture on the surface on which the cellulose-based long fibers are arranged is 200 to The knitted fabric characterized by being 330 W / m 2 · ° C.

［４］前記［１］〜［３］のいずれかに記載の編地からなり、かつ、前記セルロース系長繊維が配された面が着用時に肌側に位置する繊維製品。 [4] A fiber product comprising the knitted fabric according to any one of [1] to [3], and having a surface on which the cellulose-based long fibers are arranged positioned on the skin side when worn.
本発明の編地は、吸湿性に優れるために不感蒸泄時や少量の発汗時にムレがなく快適で、運動等により発汗した際にも、その汗によるベタツキ感や濡れ感を感じにくく、肌触りも良好であるため、インナーウエア、スポーツウエア、寝具用の編地として使用することができる。 The knitted fabric of the present invention is comfortable without moisture during insensitive steaming or a small amount of sweat due to its excellent hygroscopicity, and even when sweating due to exercise etc., it is difficult to feel the stickiness and wetness due to sweat, and the touch Can also be used as a knitted fabric for innerwear, sportswear and bedding.
以下、本発明について詳細に説明する。
本発明の編地には、セルロース系長繊維が約５〜約２５％含まれている。
セルロース系長繊維とは、レーヨン、キュプラ、アセテート等の再生セルロース長繊維をいい、綿や再生セルロース短繊維などのセルロース短繊維に比べ、毛羽が少なく、糸表面がなめらかであるため肌への摩擦抵抗が小さく、肌触りが良い。再生セルロース長繊維のうちレーヨン長繊維、キュプラ長繊維は、原料の綿に比べ繊維の水分率も大きく吸湿効果が大きいため、好ましい。特にキュプラ長繊維はレーヨン長繊維に比べて繊維１本の表面形状もなめらかであり、繊度も細いため非常に肌触りが良く、より好ましい。これらの繊維を肌側に配することにより、吸湿性と肌触りに優れ、不感蒸泄時や少量の発汗時にムレがなく快適な編地とすることができる。セルロース長繊維の含有量が約５％より低いと吸湿性が小さく、肌触り改善効果が期待できず編地は快適性に劣り、一方、約２５％を超える場合には後述する発汗時のべたつきが大きくなるため、編地は快適性に劣る。
Hereinafter, the present invention will be described in detail.
The knitted fabric of the present invention contains about 5 to about 25% of cellulosic long fibers.
Cellulose-based long fibers refer to regenerated cellulose long fibers such as rayon, cupra, and acetate. They have fewer fuzz and have a smoother thread surface than cellulose short fibers such as cotton and regenerated cellulose short fibers, and therefore, friction on the skin. Low resistance and good touch. Among the regenerated cellulose long fibers, rayon long fibers and cupra long fibers are preferable because the moisture content of the fibers is large and the moisture absorption effect is large compared to the raw cotton. In particular, the cupra long fiber is more preferable because it has a smoother surface shape than one rayon long fiber and has a finer fineness, so that it is very soft to the touch. By arranging these fibers on the skin side, the fabric is excellent in hygroscopicity and touch, and can be made into a comfortable knitted fabric without stuffiness during insensitive steaming or a small amount of sweating. When the content of cellulose long fiber is lower than about 5%, the hygroscopicity is small, and the knitted fabric is inferior in comfort because the effect of improving the touch cannot be expected. On the other hand, when it exceeds about 25%, the stickiness during sweating described later Since it becomes large, the knitted fabric is inferior in comfort.
セルロース系長繊維の繊度は特に限定されないが、約２２〜約８４デシテックス（ｄｔｅｘ）が好ましく、約３３〜約５６ｄｔｅｘがより好ましい。セルロース系長繊維の単糸繊度も特に限定されないが約０．５〜約２ｄｔｅｘが、肌触りの観点から、好ましい。 The fineness of the cellulosic long fibers is not particularly limited, but is preferably about 22 to about 84 dtex, and more preferably about 33 to about 56 dtex. The single yarn fineness of the cellulosic long fibers is not particularly limited, but about 0.5 to about 2 dtex is preferable from the viewpoint of the touch.
セルロース系長繊維を編地に含有させる際に、ポリエステル系やポリアミド系などの合繊の長繊維や短繊維と交編して用いることが可能であるが、セルロース系長繊維は、ポリエステル系又はポリアミド系長繊維との複合糸として編地に配されていることが、汗処理の観点から好ましい。複合する際には肌触りを損ねないよう、合繊の長繊維の繊度が約２２〜約８４ｄｔｅｘ、単糸繊度が約０．５〜約２ｄｔｅｘのマルチフィラメント糸が好ましい。合繊の長繊維は、汗をかいた際の拡散による汗処理の観点から異型断面であることが好ましく、Ｗ型断面繊維は異型で扁平であるため、汗処理とやわらかさの双方を満たし、より好ましい。 When the cellulosic long fibers are incorporated into the knitted fabric, they can be used by knitting with long fibers or short fibers of synthetic fibers such as polyester or polyamide. It is preferable that it is arranged on the knitted fabric as a composite yarn with system long fibers from the viewpoint of sweat treatment. A multifilament yarn having a fineness of the synthetic long fiber of about 22 to about 84 dtex and a single yarn fineness of about 0.5 to about 2 dtex is preferable so as not to impair the touch when compositing. The long fiber of synthetic fiber preferably has an atypical cross section from the viewpoint of sweat treatment by diffusion when sweating, and the W-shaped cross-section fiber is atypical and flat, satisfying both sweat treatment and softness, and more preferable.
このような、セルロース系長繊維と合繊の長繊維との複合糸は、他の繊維と交編されて編地に配される。交編相手は合繊の長繊維、特にポリエステル系又はポリアミド系長繊維であることが好ましく、繊度が約２２〜約８４ｄｔｅｘ、単糸繊度が約０．５〜約２ｄｔｅｘのマルチフィラメント糸が好ましい。 Such a composite yarn of cellulosic long fibers and synthetic long fibers is knitted with other fibers and arranged on the knitted fabric. The knitting partner is preferably a synthetic long fiber, particularly a polyester or polyamide long fiber, and a multifilament yarn having a fineness of about 22 to about 84 dtex and a single yarn fineness of about 0.5 to about 2 dtex is preferred.
本発明の編地は、編地の少なくとも一方の表面にはセルロース系長繊維が配されず、編地の他方の表面、又は編地の他方の表面及び編地中間層にセルロース系長繊維が配された構造であることを特徴としている。以下、セルロース系長繊維が配されていない面を編地表面、セルロース系長繊維が配されている面を編地裏面と呼称する。この編地の表裏は、編地製造における表裏と同一であっても異なっていてもよいが、後述する編成条件の点から、同一であることが好ましい。 In the knitted fabric of the present invention, cellulosic long fibers are not arranged on at least one surface of the knitted fabric, and cellulosic long fibers are on the other surface of the knitted fabric, or the other surface of the knitted fabric and the knitted fabric intermediate layer. It is characterized by an arranged structure. Hereinafter, the surface on which the cellulose-based long fibers are not disposed is referred to as a knitted fabric surface, and the surface on which the cellulose-based long fibers are disposed is referred to as a knitted fabric back surface. The front and back of the knitted fabric may be the same as or different from the front and back of the knitted fabric, but are preferably the same from the viewpoint of the knitting conditions described later.
編地の少なくとも一方の表面にセルロース系長繊維が配されていることによって、この面（裏面）を繊維製品の着用時肌側（肌面）に配置したときに、目的の肌触りや快適性を得ることができる。しかしながら、編地の両面にセルロース系長繊維が配されていると、着用時の繊維製品表面側が摩擦で糸切れが発生しやすく、また、他の交編又は複合繊維と色差や光沢差が生じやすく外観を損なうおそれがある。 When cellulose-based long fibers are arranged on at least one surface of the knitted fabric, when this surface (back surface) is placed on the skin side (skin surface) when the fiber product is worn, the desired feel and comfort are achieved. Can be obtained. However, when cellulosic long fibers are arranged on both sides of the knitted fabric, thread breakage tends to occur on the fiber product surface side when worn, and color differences and gloss differences occur with other knitted or composite fibers. It is easy to damage the appearance.
本発明の編地の厚みは約０．５〜約１．２ｍｍである。
編地の厚みは、Ｐｅａｃｏｃｋ社製の厚み測定器を用い、φ３．０ｃｍの測定部を５ｇの荷重にて編地に接触させ、３か所で測定して平均する。厚みが約０．５ｍｍより小さい場合には汗処理性に乏しく、快適感が得にくく、一方、厚みが約１．２ｍｍを超える場合には生地のごわつきが大きくなり、肌触りを損ねる。
The thickness of the knitted fabric of the present invention is about 0.5 to about 1.2 mm.
The thickness of the knitted fabric is averaged by using a thickness measuring device manufactured by Peacock and contacting a measuring part of φ3.0 cm with the load of 5 g and measuring at three places. When the thickness is less than about 0.5 mm, the sweat treatment property is poor and it is difficult to obtain a comfortable feeling. On the other hand, when the thickness exceeds about 1.2 mm, the fabric becomes stiff and impairs the touch.
また、本発明の編地には、裏面、すなわちセルロース系長繊維が配された側の面に凹凸があり、該表面の凸部と凹部の高さの差は約０．１５〜約０．５０ｍｍである。
編地の表面に凹凸をつけることで接触冷温感が小さくなるために、この面を肌面として使用したときに、汗をかいたときのベタツキを軽減することが可能となる。凸部と凹部の高さの差が約０．１５ｍｍ未満では肌との接触面積が凹凸のないものと変わらないことから、凹凸があるとはいえず、編地のベタツキ感が大きくなるため好ましくない。これに反し、凸部と凹部の高さの差が約０．１５ｍｍ以上であれば、編地のセルロースを含む側を肌面として着用した時の肌と編地の接触面積が少なくなり、編地が水分を吸った時にベタツキ感が低減される。一方、凸部と凹部の高さの差が約０．５０ｍｍを超えると、着用等で圧力がかかったときに、凸部が折れ曲がり、結果的には接触面積が大きくなり、ベタツキ感が大きくなることがあり、また、生地として厚みの大きいものとなり、ごわつきが大きくなる他、蒸れる等の着用感を損なうことがあるため、好ましくない。
Further, the knitted fabric of the present invention has irregularities on the back surface, that is, the surface on which the cellulose-based long fibers are arranged, and the difference in height between the convex portions and the concave portions on the surface is about 0.15 to about 0.00. 50 mm.
By making the surface of the knitted fabric uneven, the feeling of contact cold / warmness is reduced. Therefore, when this surface is used as a skin surface, stickiness when sweating can be reduced. If the difference in height between the convex part and the concave part is less than about 0.15 mm, the contact area with the skin does not change from that having no irregularities, so it cannot be said that there are irregularities and is preferable because the knitted fabric is more sticky. Absent. On the other hand, if the difference in height between the convex portion and the concave portion is about 0.15 mm or more, the contact area between the skin and the knitted fabric when the cellulose-containing side of the knitted fabric is worn as the skin surface is reduced, and the knitting When the ground absorbs moisture, the feeling of stickiness is reduced. On the other hand, if the difference in height between the convex portion and the concave portion exceeds about 0.50 mm, the convex portion is bent when pressure is applied by wearing or the like, resulting in a large contact area and a feeling of stickiness. In addition, it is not preferable because the fabric is thick and thick, and the wearing feeling such as stuffiness may be impaired.
凸部と凹部の高さの差は、編地の断面写真を電子顕微鏡等で撮影し、編地の表側、すなわちセルロース系長繊維が表面に出ていない側の表面層を基準とし、編地の裏側の凸部までの高さを５か所で測定して平均する。また、同様に表側から裏側の凹部までの高さを５か所で測定して平均する。それぞれの平均値から、凸部と凹部の高さの差を、下記式により算出する：
凸部と凹部の高さの差＝（編地表側から編地裏側の凸部までの高さの平均）−（編地表側から編地裏側の凹部までの高さの平均値） 式（１）
The difference in height between the convex part and the concave part is obtained by taking a cross-sectional photograph of the knitted fabric with an electron microscope or the like, and using the surface layer on the front side of the knitted fabric, that is, the side on which the cellulose-based long fibers are not exposed, as a reference. The height to the convex part on the back side of is measured at five places and averaged. Similarly, the height from the front side to the concave part on the back side is measured at five places and averaged. From the respective average values, the difference in height between the convex and concave portions is calculated by the following formula:
Difference in height between the convex portion and the concave portion = (average height from the knitted fabric surface side to the convex portion on the back side of the knitted fabric) − (average value of height from the knitted fabric front side to the concave portion on the back side of the knitted fabric) Formula (1 )
凸部と凹部との差は、約０．２０〜約０．５０ｍｍであればより好ましく、さらに好ましくは約０．２３〜約０．４５ｍｍ、特に好ましくは約０．２４〜約０．４０ｍｍである。 The difference between the convex portion and the concave portion is more preferably about 0.20 to about 0.50 mm, further preferably about 0.23 to about 0.45 mm, and particularly preferably about 0.24 to about 0.40 mm. is there.
本発明の編地は、セルロース系長繊維が配された面（裏面）の２００ｇ／ｍ２水分付与時の接触冷感性が約２００〜約３３０Ｗ／ｍ２・℃である。該接触冷感性は、好ましくは約２００〜約２８０Ｗ／ｍ２・℃、より好ましくは約２００〜約２４０Ｗ／ｍ２・℃である。
接触冷感性の測定には、カトーテック社製のサーモラボＩＩを使用する。この装置は温められた熱板を試料上に置いたときの熱の移動量を測定するものである。具体的な測定方法は以下のとおりである。
測定に使用する試料を２０℃、６５％ＲＨ環境下で２４時間調湿した後、８ｃｍ×８ｃｍにサンプリングし、編地裏面（セルロース長繊維が配された面）を上にして置いた編地サンプルに、２０℃、６５％ＲＨ環境下で３０℃に温められた熱板を載せた瞬間の最大熱移動量を測定する。
Knitted fabric of the present invention, cool contact sensitivity at 200 g / m 2 moisturizing face of cellulosic filaments was arranged (back surface) of about 200 to about 330W / m 2 · ℃. The cool contact sensitive is preferably from about 200 to about 280W / m 2 · ℃, more preferably from about 200 to about 240W / m 2 · ℃.
Thermolab II manufactured by Kato Tech Co., Ltd. is used for measuring the contact cooling sensitivity. This apparatus measures the amount of heat transferred when a heated hot plate is placed on a sample. The specific measurement method is as follows.
The sample used for measurement was conditioned for 24 hours in an environment of 20 ° C. and 65% RH, then sampled to 8 cm × 8 cm, and the knitted fabric was placed with the back of the knitted fabric (the surface on which the cellulose long fibers were placed) facing up The maximum amount of heat transfer at the moment when a hot plate heated to 30 ° C. in an environment of 20 ° C. and 65% RH is placed on the sample is measured.
２００ｇ／ｍ２の水分を付与したときの水分は、かなり汗をかくような運動をした時に布帛が吸う汗の水分量を想定した条件である。
測定時の水分の付与方法は、試料の裏側に霧吹きにて、８ｃｍ×８ｃｍにサンプリングされた試料の重量が＋１．２８ｇになるように水分を付与すればよい。このときの霧吹き内の水温は２０℃である。
編地の肌に接触する側に水分が残っていると、水の熱伝導率が高いため、熱板から熱を多量に奪い、接触冷感性が大きくなる。すわなち、接触冷感性が大きい試料はベタツキ感が大きいことを意味し、約３３０Ｗ／ｍ２・℃を超えるとベタツキ感が非常に大きく好ましくない。約２００Ｗ／ｍ２・℃未満は、ベタツキ感が小さいため、好ましいが、本発明ではセルロース繊維が生地裏面に存在しているため、接触冷感性を約２００Ｗ／ｍ２・℃未満にするためには凹凸を著しく大きくする必要があり、肌触りの観点からは、好ましくない。尚、従来のセルロースを表面に含む編地は通常約３３０Ｗ／ｍ２・℃を大きく超えるが、本発明では、編地裏面の凹凸状態をコントロールすることにより、多量の水分が付与された状態でもベタツキ性が改良された編地となる。
Moisture when 200 g / m 2 of moisture is applied is a condition that assumes the amount of sweat moisture that the fabric absorbs when exercised to sweat a lot.
As a method for applying moisture at the time of measurement, water may be applied so that the weight of the sample sampled to 8 cm × 8 cm is +1.28 g by spraying on the back side of the sample. The water temperature in the spray bottle at this time is 20 ° C.
If moisture remains on the side of the knitted fabric that comes into contact with the skin, the heat conductivity of water is high, so a large amount of heat is taken away from the hot plate, and the contact cooling sensitivity is increased. In other words, a sample having a high contact cooling sensitivity means that the stickiness is large, and if it exceeds about 330 W / m 2 · ° C., the stickiness is very large, which is not preferable. Less than about 200 W / m 2 · ° C. is preferable because the feeling of stickiness is small, but in the present invention, cellulose fibers are present on the back of the fabric, so that the contact cooling sensitivity is less than about 200 W / m 2 · ° C. Is not preferable from the viewpoint of touch. In addition, although the knitted fabric which contains the conventional cellulose on the surface generally exceeds about 330 W / m < 2 > (degreeC), in this invention, even in the state where a lot of moisture was given by controlling the uneven state of the back of the knitted fabric. A knitted fabric with improved stickiness.

捲縮糸の上端を固定し、下端に１．７７×１０-３ｃＮ／ｄｔの荷重をかけ、３０秒後の長さ（Ａ）を測定する。次いで、１．７７×１０-３ｃＮ／ｄｔの荷重を取り外し、０．０８８ｃＮ／ｄｔの荷重をかけ、３０秒後の長さ（Ｂ）を測定し、下記式（２）により捲縮伸長率を求める：
捲縮伸長率（％）＝｛（Ｂ−Ａ）／Ａ｝×１００ 式（２）
The material used for the knitted fabric of the present invention may have crimps, and the crimp elongation rate is preferably 0 to 150% from the viewpoint of touch. The crimp elongation of the false twisted yarn is measured under the following conditions.
The upper end of the crimped yarn is fixed, a load of 1.77 × 10 −3 cN / dt is applied to the lower end, and the length (A) after 30 seconds is measured. Next, the load of 1.77 × 10 −3 cN / dt was removed, the load of 0.088 cN / dt was applied, the length (B) after 30 seconds was measured, and the crimp elongation rate was obtained by the following formula (2) Ask for:
Crimp elongation (%) = {(B−A) / A} × 100 Formula (2)
本発明の編地は、機能的には２層以上の層構造となっている。表裏２層構造で構成されていればよく、中間層をもつ３層以上でも構わないし、シングル編地でもプレーティング等で機能的に２層と同等の働きをする編地ならばそれでも構わない。
本発明の編地を作製するための編機としては、横編機やシングル丸編機、ダブル丸編機、トリコット編機、ラッセル編機等を使用できるが、２層以上の層を持つ多層編地を作製するためにはダブル丸編機が好ましい。使用する編機の編ゲージとしては約１０〜約４０ＧＧが好ましい。
The knitted fabric of the present invention functionally has a layer structure of two or more layers. It may be constituted by a front and back two-layer structure, and may be three or more layers having an intermediate layer, or may be a single knitted fabric or a knitted fabric functionally equivalent to two layers by plating or the like.
As a knitting machine for producing the knitted fabric of the present invention, a flat knitting machine, a single circular knitting machine, a double circular knitting machine, a tricot knitting machine, a Russell knitting machine, etc. can be used, but a multilayer having two or more layers. In order to produce a knitted fabric, a double circular knitting machine is preferable. The knitting gauge of the knitting machine to be used is preferably about 10 to about 40 GG.
本発明の編地を作製するための編組織としては、ダブル丸編み地の場合、タックリバーシブル、デンプルメッシュ、コンフォート等が使用できるが、これに限定されるものではない。しかし、編組織としては、地裏側に凹凸が得られるタック編みを使用した組織が好ましい。また、シングル編機のプレーティング組織も可能であり、経編では例えば3枚筬でミドルにセルロース系繊維を配し、凹凸を発現する組織にすれば所望の効果が奏される。 As the knitting structure for producing the knitted fabric of the present invention, in the case of a double circular knitted fabric, tuck reversible, dimple mesh, comfort and the like can be used, but are not limited thereto. However, the knitting structure is preferably a structure using tuck knitting that provides unevenness on the back side. In addition, a plating structure of a single knitting machine is also possible. In warp knitting, for example, a cellulose fiber is arranged in the middle of three sheets, and a desired effect can be obtained by forming a structure that expresses unevenness.
本発明の編地表裏のコース方向のループ数は編成上問題なければ特に限定されない。
本発明の編地は、セルロース系長繊維を５〜２５％含んでおり、セルロース系長繊維が編地の裏面側に配されているため、編地の裏面がやわらかく、皮膚摩擦抵抗値が小さい。セルロース系長繊維を含まない場合には本発明のように凹凸をつけた編地の面の摩擦抵抗値は非常に大きいものになる。本発明におけるセルロース系長繊維が配された面は、後述する方法で測定される皮膚摩擦抵抗値が約１０〜約１７V・Sであることが好ましい。皮膚摩擦抵抗値が１０〜１７V・Sであれば皮膚刺激が小さいと言える。抵抗値が約１７V・Sより大きい場合は、ザラザラ感が大きく、不快であり、一方、約１０V・Sより小さければ皮膚刺激性は低くなるが、なめらか過ぎるために凹凸が小さくなり、汗処理性が低下してしまう。
The number of loops in the course direction on the front and back of the knitted fabric of the present invention is not particularly limited as long as there is no problem in knitting.
The knitted fabric of the present invention contains 5 to 25% of cellulosic long fibers, and since the cellulosic long fibers are arranged on the back side of the knitted fabric, the back side of the knitted fabric is soft and the skin friction resistance value is small. . When cellulosic long fibers are not included, the frictional resistance value of the surface of the knitted fabric with unevenness as in the present invention becomes very large. The surface on which the cellulose-based long fibers are arranged in the present invention preferably has a skin friction resistance value of about 10 to about 17 V · S measured by a method described later. If the skin frictional resistance value is 10 to 17 V · S, it can be said that the skin irritation is small. When the resistance value is greater than about 17 V · S, the feeling of roughness is large and uncomfortable. On the other hand, when the resistance value is less than about 10 V · S, the skin irritation is low, but the smoothness is too smooth and the unevenness is reduced, resulting in sweat treatment. Will fall.
本発明の編地の目付は特に限定されないが、約５０〜約３００ｇ／ｍ２が好ましく、より好ましくは約８０〜約２５０ｇ／ｍ２である。 The basis weight of the knitted fabric of the present invention is not particularly limited, but is preferably about 50 to about 300 g / m 2 , more preferably about 80 to about 250 g / m 2 .
また、本発明の編地には吸水加工を施すことが望ましい。
本発明の編地の表側を外気側、セルロース系繊維が含まれる裏側を肌側になるように用いた衣類は、本発明の効果が奏されるため好ましい。
本発明の編地は、スポーツウエアやインナー等の汗処理機能が必要な衣料用途に好適であるがこれに限定されず、アウターや裏地等の衣料や、シーツ等の寝具、さらには失禁パンツ等の衛生物品にも適用でき、吸湿性能による快適性を持ち、かつ水分によるベタツキ感や冷え感を低減する効果を発揮する。
Moreover, it is desirable to perform a water absorption process on the knitted fabric of the present invention.
A garment in which the front side of the knitted fabric of the present invention is the outside air side and the back side containing the cellulosic fibers is the skin side is preferable because the effects of the present invention are exhibited.
The knitted fabric of the present invention is suitable for clothing applications that require a sweat treatment function such as sportswear and inner, but is not limited to this, clothing such as outer and lining, bedding such as sheets, and incontinence pants, etc. It can be applied to other sanitary goods, has comfort due to moisture absorption performance, and exhibits the effect of reducing the feeling of stickiness and cooling due to moisture.
本発明の編地は、表側を構成する編地の編密度を裏側の編密度より大きくすることにより、又は表側の糸繊度を裏側の糸繊度より小さくすることにより、毛細管現象を発現させて裏側から表側へ水分を移動させてもよい。このような、水分移動機能を有する本発明の編地裏側を、衣類の肌面として着用すれば、多量の発汗時でも肌面に水分が残りにくく、着用時のベタツキ感や冷え感をさらに軽減することができる。
毛細管現象を発現させるには編地表側のウェル方向のループ数が多層編地裏側のウェル方向のループ数の約１．１倍〜約４．５倍にするのがよい。表裏のウェル方向のループ数は、幅２．５４ｃｍ（１インチ）当たりの編目ループの数をデンシメーターやリネンテスター等で測定する。ここでループ数とは、編地の表裏それぞれに確認されるニットループの編目の数であり、タックループやシンカーループといった編目はループ数に含まない。
In the knitted fabric of the present invention, the knitted fabric of the knitted fabric constituting the front side is made larger than the knitted density on the back side, or the yarn fineness on the front side is made smaller than the yarn fineness on the back side, so that the capillary phenomenon is expressed and the back side Moisture may be moved from the surface to the front side. If the back side of the knitted fabric of the present invention having such a moisture transfer function is worn as the skin surface of clothing, moisture hardly remains on the skin surface even when sweating a lot, and the feeling of stickiness and cooling when worn is further reduced. can do.
In order to develop capillary action, the number of loops in the well direction on the knitted fabric surface side is preferably about 1.1 to 4.5 times the number of loops in the well direction on the back side of the multilayer knitted fabric. The number of loops in the well direction on the front and back sides is determined by measuring the number of stitch loops per width of 2.54 cm (1 inch) with a densimeter, a linen tester or the like. Here, the number of loops is the number of stitches of the knit loop confirmed on the front and back of the knitted fabric, and stitches such as tack loops and sinker loops are not included in the number of loops.
