Description
本発明は、有機繊維からなり少なくとも１面に撥水剤が付着してなる織編物であって、ソフトな風合いを損なわずかつぬれ感の少ない織編物およびかかる織編物を用いてなる繊維製品に関するものである。 The present invention relates to a woven or knitted fabric made of an organic fiber and having a water repellent attached to at least one surface thereof, which does not impair a soft texture and has little wet feeling, and a textile product using such a woven or knitted fabric. Is.
従来、ぬれ感の少ない織編物としては、布帛の表面層を疎水性繊維で構成し、一方裏面層を親水性繊維で構成した多層構造布帛（例えば特許文献１参照）や、生地全体を撥水加工した後に、裏面をオゾン処理して吸水性を付与したもの（例えば特許文献２参照）などが提案されている。これらは、裏面に吸水性を付与することによりぬれ感の減少を狙ったものであるが、裏面に汗が残留するためぬれ感が十分には減少しないという問題があった。 Conventionally, as a woven or knitted fabric with little wet feeling, a multilayer structure fabric (for example, refer to Patent Document 1) in which the surface layer of the fabric is composed of hydrophobic fibers and the back layer is composed of hydrophilic fibers, or the entire fabric is water-repellent. After processing, the thing which gave the water absorption by processing the back surface with ozone (for example, refer to patent documents 2) etc. is proposed. These aim to reduce the wet feeling by imparting water absorption to the back surface, but there is a problem that the wet feeling is not sufficiently reduced because sweat remains on the back surface.
また特許文献３では、織編物の片面に撥水剤を縦横格子状や線状などの模様状に塗布し、肌側裏面における汗の拡散を防止した、ぬれ感の少ない織編物が提案されている。しかしながら、撥水剤を縦横格子状や線状などの模様状に塗布するとぬれ感は低減できるものの、塗布された撥水剤によりソフトな風合いが損なわれるという問題があった。 Further, Patent Document 3 proposes a woven or knitted fabric with less wetting feeling in which a water-repellent agent is applied to one side of a woven or knitted fabric in a pattern such as a vertical and horizontal lattice pattern or a linear pattern to prevent sweat from spreading on the back side of the skin. Yes. However, when the water repellent is applied in a pattern such as vertical and horizontal lattices or lines, the wet feeling can be reduced, but there is a problem that the soft texture is impaired by the applied water repellent.
本発明は、上記の背景に鑑みなされたものであり、その目的は、ソフトな風合いを損なわずぬれ感の少ない織編物およびかかる織編物を用いてなる繊維製品を提供することにある。 The present invention has been made in view of the above-described background, and an object of the present invention is to provide a woven or knitted fabric with less wet feeling without impairing a soft texture and a fiber product using the woven or knitted fabric.
本発明者は、上記目的を達成するため鋭意検討した結果、有機繊維からなる織編物に、少なくとも多角形が角部で連続する部分を有するパターンで撥水剤を塗布することにより、所望のソフトな風合いを損なわずぬれ感の少ない織編物が得られることを見出し、さらに鋭意検討を重ねることにより本発明に想到した。 As a result of intensive studies to achieve the above object, the present inventor applied a water repellent to a woven or knitted fabric made of organic fibers in a pattern having at least a polygonal continuous portion at the corners, thereby achieving a desired softness. The present invention has been conceived by finding that a woven or knitted fabric with little wet feeling can be obtained without impairing the natural texture, and further intensive studies.
かくして、本発明によれば「ポリエステル繊維からなり、親水化処理が施された織編物の少なくとも一面に、少なくとも多角形が角部で連続する部分を有しかつ該多角形の一辺の長さが０．７〜１．５ｍｍの範囲内であるパターンで撥水剤が付着してなるぬれ感の少ない織編物を用いてなることを特徴とする、スポーツ衣料、インナー衣料、紳士衣料、および婦人衣料の群より選ばれるいずれかの繊維製品。」が提供される。 Thus, according to the present invention consists of "polyester fibers, at least one surface of the woven or knitted fabric which hydrophilic treatment is performed, at least the length of the polygon of the chromatic vital polygonal portion continuous with the corner portion side is Sports apparel, inner apparel, men's apparel, and women's apparel characterized by using a woven or knitted fabric with a little wet feeling formed by adhering a water repellent in a pattern within a range of 0.7 to 1.5 mm Any fiber product selected from the group of "is provided.
その際、撥水剤が織編物の片面にのみ付着していることが好ましい。また、多角形としては、四角形または三角形が好ましい。さらに、撥水剤の付着パターンにおいて、塗布部の面積比率が３０〜８５％の範囲内であることが好ましい。 In that case, it is preferable that the water repellent is attached only to one side of the woven or knitted fabric.

以下、本発明の実施の形態について詳細に説明する。
本発明の織編物は有機繊維で構成され、織編物の少なくとも一面に、少なくとも多角形が角部で連続する部分を有するパターンで撥水剤が付着している。ここで、撥水剤は織編物の両面に付着していてもよいが、片面だけに付着していることが好ましい。片面だけに付着させ、該面を裏面、すなわち織編物を衣料に使用した際に人体の肌側となる面とすることにより、発汗時に汗をすばやく吸収し外気側の面に拡散するため速乾性も得られる。また、撥水剤が片面だけに付着していると、ソフトな風合いも損なわれにくく好ましい。なお、撥水剤の織編物の厚さ方向への浸透度合は、撥水剤が付与された面から厚さの１／２以下（より好ましくは１／５以下）であることが好ましい。
Hereinafter, embodiments of the present invention will be described in detail.
The woven or knitted fabric of the present invention is composed of organic fibers, and a water repellent agent is attached to at least one surface of the woven or knitted fabric in a pattern having at least a polygonal continuous portion. Here, the water repellent agent may be attached to both surfaces of the woven or knitted fabric, but it is preferable that the water repellent agent is attached to only one surface. Quick-drying because it adheres to only one side and the side is the back side, that is, the side that becomes the skin side of the human body when woven or knitted fabric is used for clothing, so that sweat can be absorbed quickly and diffused to the outside side when sweating. Can also be obtained. In addition, it is preferable that the water repellent is attached to only one surface because the soft texture is hardly impaired. The penetration degree of the water repellent in the thickness direction of the woven or knitted fabric is preferably 1/2 or less (more preferably 1/5 or less) of the thickness from the surface to which the water repellent is applied.
また、少なくとも多角形が角部で連続する部分を有するパターンとは、多角形が四角形の場合を図１に模式的に示すように、多角形同士がその角部で接触している個所を有するパターンである。このように、多角形が角部で経方向および緯方向に連続していると、汗等の水は島状の非撥水部を通して、厚み方向に拡散する。その結果、撥水剤が付与された面には水がほとんど残らないので、ぬれ感は低減される。同時に、多角形同士が角部で点接触しているので、ソフトな風合いが損なわれるおそれがない。一方、図２に模式的に示す従来の縦横格子状パターンで撥水剤が付着していると、ぬれ感は低減できるもののソフトな風合いが損なわれるため好ましくない。 Further, the pattern having at least a portion where the polygons are continuous at the corners has a portion where the polygons are in contact with each other at the corners, as schematically shown in FIG. It is a pattern. In this way, when the polygon is continuous at the corners in the longitudinal direction and the weft direction, water such as sweat diffuses in the thickness direction through the island-shaped non-water-repellent portion. As a result, almost no water remains on the surface to which the water repellent is applied, so that the wet feeling is reduced. At the same time, since the polygons are in point contact at the corners, there is no possibility that the soft texture is impaired. On the other hand, when the water repellent is attached in the conventional vertical and horizontal grid pattern schematically shown in FIG. 2, the wet feeling can be reduced, but the soft texture is impaired, which is not preferable.
ここで、多角形としては、四角形または三角形が好ましい。また、多角形のサイズとしては、多角形の一辺の長さが０．５〜２．０ｍｍ（より好ましくは０．７〜１．５ｍｍ）の範囲内であることが好ましい。該長さが０．５ｍｍよりも小さくても、逆に２．０ｍｍよりも大きくても、吸水性が低下するため十分にぬれ感を低減できないおそれがある。 Here, the polygon is preferably a quadrangle or a triangle. Further, as the size of the polygon, the length of one side of the polygon is preferably in the range of 0.5 to 2.0 mm (more preferably 0.7 to 1.5 mm). Even if the length is smaller than 0.5 mm or larger than 2.0 mm, the wettability may not be sufficiently reduced because the water absorption is lowered.
前記撥水剤の付着パターンにおいて、塗布部の面積比率は、３０〜８５％（より好ましくは４０〜７０％）の範囲内であることが好ましい。該塗布部面積比率が３０％よりも小さいと、吸水時に水が面方向にひろがり、ぬれ感を十分低減できないおそれがある。逆に、該塗布部面積比率が８５％よりも大きいと、吸水性が低下するだけでなく、ソフトな風合いを損なうおそれがある。 In the adhesion pattern of the water repellent, the area ratio of the application part is preferably in the range of 30 to 85% (more preferably 40 to 70%). If the area ratio of the coated portion is less than 30%, water may spread in the surface direction during water absorption, and the wet feeling may not be sufficiently reduced. On the contrary, if the area ratio of the coated part is larger than 85%, not only the water absorption is lowered, but there is a possibility that the soft texture is impaired.
前記塗布部面積比率は下記式で示されるものである。
塗布部面積比率（％）＝（塗布部面積）／（（塗布部面積）＋（非塗布部面積））×１００
なお、前記パターンにおいて、少なくとも多角形同士が角部でつながっている個所があればよく、多角形の全個数のうち３０％以上（好ましくは５０％以上）の多角形が他の多角形と角部でつながっていることが好ましい。また、多角形もほぼ多角形の形状をしておればよく、多角形の辺が曲線になっていてもさしつかえない。
The said application part area ratio is shown by a following formula.
Application part area ratio (%) = (application part area) / ((application part area) + (non-application part area)) × 100
In the pattern, it is sufficient that at least the polygons are connected at the corners, and 30% or more (preferably 50% or more) of the polygons are corners of other polygons. It is preferable that the parts are connected. Further, the polygon only needs to have a substantially polygonal shape, and the sides of the polygon may be curved.
本発明において、織編物の厚みが０．４〜１．５ｍｍであることが好ましい。該厚みが０．４ｍｍよりも小さいと、十分な吸水性が得られず十分にぬれ感を低減できないおそれがある。逆に該厚みが１．５ｍｍより大きいとソフトな風合いが損なわれるおそれがある。なお、織物については、その厚さをＪＩＳ Ｌ １０９６−１９９８、６．５の厚さ測定法により、編物については、その厚さをＪＩＳ Ｌ １０１８−１９９８、６．５の厚さ測定法により測定するものとする。 In the present invention, the thickness of the woven or knitted fabric is preferably 0.4 to 1.5 mm. If the thickness is less than 0.4 mm, sufficient water absorption cannot be obtained and the wet feeling may not be sufficiently reduced. Conversely, if the thickness is greater than 1.5 mm, the soft texture may be impaired. For woven fabrics, the thickness is measured by the thickness measuring method of JIS L 1096-1998, 6.5, and for the knitted fabric, the thickness is measured by the thickness measuring method of JIS L 1018-1998, 6.5. It shall be.

Illustrated. Especially, a polyester fiber is illustrated preferably by the point of quick-drying. The polyester fiber is produced from a dicarboxylic acid component and a diglycol component. As the dicarboxylic acid component, terephthalic acid is preferably used mainly, and as the diglycol component, it is preferable to use one or more alkylene glycols selected from ethylene glycol, trimethylene glycol and tetramethylene glycol. Moreover, the polyester resin may contain a third component in addition to the dicarboxylic acid component and the glycol component. Examples of the third component include cationic dye dyeable anion components such as sodium sulfoisophthalic acid; dicarboxylic acids other than terephthalic acid such as isophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacic acid; and glycol compounds other than alkylene glycol. For example, one or more of diethylene glycol, polyethylene glycol, bisphenol A, and bisphenol sulfone can be used. Further, it may be a biodegradable polyester fiber such as polylactic acid.
繊維を形成する樹脂中には、必要に応じて、艶消し剤（二酸化チタン）、微細孔形成剤（有機スルホン酸金属塩）、着色防止剤、熱安定剤、難燃剤（三酸化二アンチモン）、蛍光増白剤、着色顔料、帯電防止剤（スルホン酸金属塩）、吸湿剤（ポリオキシアルキレングリコール）、抗菌剤、その他の無機粒子の１種以上が含まれていてもよい。なかでも、微細孔形成剤を含む繊維を用いて織編物を織編成した後、繊維表面に微細孔を形成すると吸水性が向上するのでぬれ感を十分に低減することができ好ましい。 In the resin forming the fiber, a matting agent (titanium dioxide), a fine pore forming agent (organic sulfonic acid metal salt), an anti-coloring agent, a heat stabilizer, a flame retardant (antimony trioxide), if necessary. , A fluorescent brightening agent, a coloring pigment, an antistatic agent (sulfonic acid metal salt), a hygroscopic agent (polyoxyalkylene glycol), an antibacterial agent, and other inorganic particles may be contained. Among them, it is preferable to form a fine hole on the fiber surface after knitting a knitted or knitted fabric using a fiber containing a fine pore forming agent, because the water absorption is improved and the wet feeling can be sufficiently reduced.
繊維の形状としては、短繊維でもよいし長繊維（マルチフィラメント）でもよいが、吸水性の点で長繊維であることが好ましい。さらには、通常の仮撚捲縮加工が施された仮撚捲縮加工糸や２種以上の構成糸条を空気混繊加工や複合仮撚加工させた複合糸であってもよい。 The shape of the fiber may be a short fiber or a long fiber (multifilament), but is preferably a long fiber in terms of water absorption. Furthermore, a false twisted crimped yarn subjected to a normal false twist crimping process or a composite yarn obtained by subjecting two or more kinds of constituent yarns to air-mixing or composite false twisting may be used.
有機繊維の単糸繊維繊度、総繊度、単糸数は、単糸繊維繊度０．５〜５．０ｄｔｅｘ、総繊度３０〜３００ｄｔｅｘ、単糸数３０〜２００本の範囲であることが好ましい。また、単糸繊維の断面形状には制限はなく、通常の円形断面のほかに三角、扁平、くびれ付扁平、十字形、六様形、あるいは中空形などの異型断面形状であってもよい。特に、図３に模式的に示すようなくびれ付扁平断面形状を採用すると、吸水性が向上するので、ぬれ感を十分低減することができ好ましい。 The single yarn fiber fineness, total fineness, and single yarn number of the organic fiber are preferably in the range of single yarn fiber fineness of 0.5 to 5.0 dtex, total fineness of 30 to 300 dtex, and single yarn number of 30 to 200. Further, the cross-sectional shape of the single yarn fiber is not limited, and may be an irregular cross-sectional shape such as a triangular shape, a flat shape, a constricted flat shape, a cross shape, a hexagonal shape, or a hollow shape in addition to a normal circular cross section. In particular, it is preferable to employ a constricted flat cross-sectional shape as schematically shown in FIG. 3, because the water absorption is improved, so that the feeling of wetting can be sufficiently reduced.
本発明の織編物は以下の製造方法により製造することができる。
まず、前記の有機繊維を用いて織編物を織編成する。ここで、織編物の織編組織は特に限定されないが、０．４〜１．５ｍｍの厚みを得る上で、例えば、織物では、一般に経二重組織、緯二重組織、二重組織、重ね組織などと称される二層構造織物が好適に例示される。また、編物では、２枚筬または３枚筬を用いた、ハーフ組織、ハーフベース組織、サテン組織などが好適に例示される。
The woven or knitted fabric of the present invention can be produced by the following production method.
First, a woven or knitted fabric is knitted using the organic fibers. Here, the woven or knitted structure of the knitted or knitted fabric is not particularly limited. For obtaining a thickness of 0.4 to 1.5 mm, for example, in the case of a woven fabric, generally, a warp double structure, a weft double structure, a double structure, and an overlapping structure are used. A two-layered fabric called a tissue or the like is preferably exemplified. Further, in the knitted fabric, a half structure, a half base structure, a satin structure, etc., using two or three sheet ridges are preferably exemplified.
また、織編物の密度としては、吸水性の点で高密度のほうが好ましく、経緯とも１００〜２００本／２．５４ｃｍの範囲内であることが好ましい。織編物の密度が該範囲よりも小さいと十分な吸水性が得られないおそれがある。逆に、織編物の密度が該範囲より大きいと製編織性が困難となるおそれがある。 The density of the woven or knitted fabric is preferably higher in terms of water absorption, and the background is preferably in the range of 100 to 200 / 2.54 cm. If the density of the woven or knitted fabric is smaller than the above range, there is a possibility that sufficient water absorption cannot be obtained. On the other hand, if the density of the woven or knitted fabric is larger than the above range, the knitting property may be difficult.
次いで、前記織編物に必要に応じて、染色仕上げ加工や親水化加工（吸水加工）を施した後、市松格子状パターンで撥水剤を付着させる。 Next, if necessary, the woven or knitted fabric is subjected to a dyeing finishing process or a hydrophilization process (water absorption process), and then a water repellent is adhered in a checkered pattern.
ここで、撥水剤としては、特に限定されず、フッ素系、シリコン系、ワックス系などの撥水剤が例示される。また、撥水剤をバインダー樹脂とともに織編物に付着させることが、撥水性の耐久性を高める上で好ましい。かかる撥水剤としては、繊維との接触角が９０度以下（好ましくは７０度以下、さらに好ましくは５０度以下）のものが好適である。該接触角が小さい程ぬれ性がよいため、バインダー樹脂が単糸繊維表面に均一に皮膜する。その結果、撥水性の耐久性が向上するだけでなく織編物のソフトな風合いが損なわれることがない。繊維との接触角が９０度以下のバインダー樹脂としては、メラミン樹脂、エポキシ樹脂、ウレタン樹脂、アクリル系樹脂などが例示される。 Here, the water repellent is not particularly limited, and examples thereof include fluorine-based, silicon-based, and wax-based water repellents. In addition, it is preferable to attach the water repellent together with the binder resin to the woven or knitted fabric in order to improve the water repellency durability. As such a water repellent, those having a contact angle with the fiber of 90 degrees or less (preferably 70 degrees or less, more preferably 50 degrees or less) are suitable. Since the wettability is better as the contact angle is smaller, the binder resin uniformly coats the surface of the single yarn fiber. As a result, the durability of the water repellency is improved and the soft texture of the woven or knitted fabric is not impaired. Examples of the binder resin having a contact angle with the fiber of 90 degrees or less include melamine resin, epoxy resin, urethane resin, and acrylic resin.
また、撥水剤とバインダー樹脂の織編物に対する付着量としては、各々樹脂固形分重量基準で、撥水剤０．０１〜４０ｇ／ｍ２（より好ましくは１〜１０ｇ／ｍ２）、バインダー樹脂０．０１〜４０ｇ／ｍ２（より好ましくは１〜１０ｇ／ｍ２）の範囲が適当である。 The amount of water repellent and binder resin adhering to the woven or knitted fabric is 0.01 to 40 g / m 2 (more preferably 1 to 10 g / m 2 ) of water repellent, based on the weight of the resin solids. A range of 0.01 to 40 g / m 2 (more preferably 1 to 10 g / m 2 ) is appropriate.
前記の撥水剤とバインダー樹脂とは、通常両者の配合組成物として織編物に付与される。その際、かかる配合組成物は水系、溶剤系のいずれで構成してもよいが、加工工程の作業環境上水系の方が好ましい。なお、溶剤としては、トルエン、イソプロピルアルコール、ジメチルホルムアミド、メチエチルケトン、酢酸エチルなどが例示される。この配合組成物には、エポキシ系などの架橋剤を併用してもよい。さらに、織編物に対する付着性を向上させる等の目的で適当な添加剤をさらに配合してもよい。 The water repellent and the binder resin are usually applied to the woven or knitted fabric as a blended composition of both. In this case, the blended composition may be composed of either an aqueous system or a solvent system, but an aqueous system is preferable in view of the working environment of the processing step. Examples of the solvent include toluene, isopropyl alcohol, dimethylformamide, methyl ethyl ketone, and ethyl acetate. This blended composition may be used in combination with an epoxy-based crosslinking agent. Furthermore, an appropriate additive may be further blended for the purpose of improving the adhesion to the woven or knitted fabric.
前記の撥水剤、または撥水剤とバインダー樹脂とを織編物に付着させる方法としては、例えばグラビアロール法、キスロール法、泡加工法、ロータリスクリーン捺染法、フラットスクリーン法、ローラー捺染法等が例示される。また、撥水剤の塗布に際しては、撥水剤が織編物の反対面までは浸透しないよう、かつ撥水剤が付与された面において隣接する撥水性部分（多角形）の辺と辺とが接触しないように、撥水剤を含む配合組成物の粘度、スキージ等による織編物への付与圧力、捺染速度を適宜調整する必要がある。なお、前述のように、撥水剤を織編物の両面に付与してもよいが、織編物の片面にのみ付与することが好ましい。また、前述のように撥水剤の織編物の厚さ方向への浸透度合は、撥水剤が付与された面から厚さの１／２以下（より好ましくは１／５以下）であることが好ましい。 Examples of the method for attaching the water repellent or the water repellent and the binder resin to the woven or knitted fabric include a gravure roll method, a kiss roll method, a foam processing method, a rotary screen printing method, a flat screen method, and a roller printing method. Illustrated. Further, when applying the water repellent, the side of the water repellent part (polygon) adjacent to the surface to which the water repellent is applied so that the water repellent does not penetrate to the opposite surface of the woven or knitted fabric. It is necessary to appropriately adjust the viscosity of the blend composition containing the water repellent, the pressure applied to the woven or knitted fabric with a squeegee, and the printing speed so as not to come into contact with each other. As described above, the water repellent may be applied to both sides of the woven or knitted fabric, but it is preferable to apply the water repellent only to one side of the woven or knitted fabric. Further, as described above, the penetration degree of the water repellent in the thickness direction of the woven or knitted fabric is 1/2 or less (more preferably 1/5 or less) of the thickness from the surface to which the water repellent is applied. Is preferred.
かくして得られた織編物において、撥水剤が、多角形が角部で連続するパターンで付着しているので、汗等の水は島状の非撥水部を通して、すみやかに厚み方向に拡散する。その結果、撥水剤が付与された面には水がほとんど残らないので、ぬれ感は低減される。同時に厚さ方向に拡散した水はすぐ蒸発するので速乾効果も得られる。また、多角形同士が角部で点接触しているので、縦横格子状や線状などの従来のパターンに比べてソフトな風合いが得られる。 In the woven or knitted fabric thus obtained, the water repellent is adhered in a pattern in which polygons are continuous at the corners, so that water such as sweat diffuses quickly in the thickness direction through the island-shaped non-water repellent parts. . As a result, almost no water remains on the surface to which the water repellent is applied, so that the wet feeling is reduced. At the same time, the water diffused in the thickness direction evaporates immediately, so that a quick drying effect can be obtained. In addition, since the polygons are in point contact at the corners, a soft texture can be obtained as compared with conventional patterns such as vertical and horizontal grids and lines.
本発明の織編物は、スポーツ衣料、インナー衣料、紳士衣料、婦人衣料などの繊維製品として好適に使用することができる。 The woven or knitted fabric of the present invention can be suitably used as a textile product such as sports clothing, inner clothing, men's clothing, and women's clothing.
なお、本発明の織編物には、必要に応じて通常のアルカリ減量加工が施されてもよい。さらには、常法の起毛加工、紫外線遮蔽あるいは、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤、マイナスイオン発生剤等の機能を付与する各種加工を付加適用してもよい。 It should be noted that the woven or knitted fabric of the present invention may be subjected to normal alkali weight reduction processing as necessary. Further, conventional brushing processing, ultraviolet ray shielding, or various processing imparting functions such as antibacterial agent, deodorant agent, insect repellent agent, phosphorescent agent, retroreflective agent, and negative ion generator may be additionally applied.

なお、これで表される乾燥性は０〜１００までの値であり、数値が大きいほどより乾燥性が高いことを表す。ここに示した乾燥性評価法は、運動開始と共に発汗し始め、運動終了後発汗が止まることを想定した実験系評価法であり、織編物に吸水される汗量が２００ｇ／ｍ２・ｈｒ程度の運動を１時間行い、その後１０分間休息したことを想定したものである。布帛に吸水される汗量が２００ｇ／ｍ２・ｈｒ程度の運動とは、バスケットボールやテニス、ランニング等の運動を１時間程度真剣に行ったと考えれば良く、通常市販の綿Ｔシャツを上衣に着用していた場合、綿Ｔシャツは汗でぐっしょりぬれた状態となる。
（３）吸水性
ＪＩＳ Ｌ１０１８Ａ法（滴下法）の吸水速度に関する試験方法に準じて測定した。水平な試料面に滴下された１滴の水滴が吸収される時間を示した。
（４）洗濯耐久性
通常の家庭洗濯機で洗濯を行い、初期の性能から半減した際の洗濯回数を評価した。
（５）織編物の風合い
３０ｃｍ四角の織編物を男女各５名ずつ計１０名のパネラーが目隠しした状態で官能評価を行った。ソフト性の点から、ソフト（最良）、ややソフト、ややかたい、かたいの４段階に評価した。
（６）厚み
織物については、その厚さをＪＩＳ Ｌ １０９６−１９９８、６．５の厚さ測定法により、編物については、その厚さをＪＩＳ Ｌ １０１８−１９９８、６．５の厚さ測定法により測定する。
（７）接触角
接触角測定装置（エルマ販売（株）製）により、バインダー樹脂と通常のポリエチレンテレフタレート繊維との接触角を測定した。
(1) Wetting feeling First, 0.3 cc of water is placed on an acrylic plate, and a woven or knitted fabric cut into a 10 cm square is placed on the acrylic plate, while applying a load of 2.9 mN / cm 2 (0.3 gf / cm 2 ). After sufficiently absorbing water in the woven or knitted fabric for 30 seconds, the woven or knitted fabric absorbed in water was placed on a total of 10 panelists' upper arms for 5 men and women, and the sensory evaluation of the wet feeling was performed. The evaluation was made on the basis of a wet feeling, and was evaluated in four levels, that is, a minimum (best), a small, a medium, and a large. In addition, the amount of water of 0.3 ml placed on the acrylic plate was a sufficient amount to wet and spread over the entire 10 cm square fabric.
(2) Dryability
First, the initial mass (A) of a woven or knitted fabric cut into a 10 cm square was measured, and the woven or knitted fabric was placed on a constant temperature plate placed at a constant temperature of 32 ° C., and 0.2 cc / min from the back of the woven or knitted fabric with a metering pump. Water at a speed of 10 minutes to give excess moisture to the fabric. After 10 minutes, the water supply is stopped, and the amount of the knitted and knitted material (B) at this time is measured and left in a constant temperature room at 32 ° C. After standing for 10 minutes, the amount of woven / knitted material (C) was measured again, and the drying property was evaluated by the following formula.
Dryability (%) = ((BC) / (BA)) × 100
In addition, the drying property represented by this is a value from 0 to 100, and the larger the numerical value, the higher the drying property. The dryness evaluation method shown here is an experimental evaluation method that assumes that sweating begins at the start of exercise and that sweating stops after the end of exercise, and the amount of sweat absorbed by the woven or knitted fabric is about 200 g / m 2 · hr. It is assumed that the exercise was performed for 1 hour and then rested for 10 minutes. The exercise with the amount of sweat absorbed by the fabric of about 200 g / m 2 · hr can be thought of as a serious exercise of basketball, tennis, running, etc. for about an hour, and usually wears a commercially available cotton T-shirt on the upper garment If so, the cotton T-shirt will be wet with sweat.
(3) Water absorption It measured according to the test method regarding the water absorption speed of JIS L1018A method (drop method). The time for one drop of water dropped on the horizontal sample surface to be absorbed is shown.
(4) Washing durability Washing was performed with a normal home washing machine, and the number of washings when the performance was reduced by half from the initial performance was evaluated.
(5) Texture of woven or knitted fabric Sensory evaluation was performed in a state in which a total of 10 panelists of 5 men and women blindfolded a 30 cm square woven or knitted fabric. From the viewpoint of softness, it was evaluated in four levels: soft (best), slightly soft, slightly hard, and hard.
(6) Thickness For woven fabrics, the thickness is measured according to JIS L 1096-1998, 6.5, and for knitted fabrics, the thickness is measured according to JIS L 1018-1998, 6.5. Measure with
