Description

【０００１】
【発明の属する技術分野】
本発明は、ソフトな風合いを損なうことなく、優れた吸汗性と耐摩耗性を有する低通気度織物に関するものである。
【０００２】
【従来の技術】
従来より、スポーツ衣料やユニフォームなどの分野で低通気度織物が多数提案されている。そして、かかる低通気度織物としては、ポリエステルやポリアミドなどの合成繊維を用いた高密度織物や、織物表面に樹脂などのコーテイング加工を施したもの、さらにはカレンダー加工を施したものなどが知られている。
【０００３】
しかしながら、これら高密度織物や、織物表面にコーテング加工やカレンダー加工を施したものは、通常風合いが硬く、また、織物表面の摩耗に対する強度（耐摩耗性）が低く、その改善が求められていた。
【０００４】
他方、合成繊維からなる織物では、綿などの天然繊維からなる編物と比較して、吸汗性に劣るという欠点があった。
【０００５】
かかる吸汗性を合成繊維に付与する方法としては、親水化剤を用いて織物に吸水加工を施すことが知られているが、用途によっては、さらに優れた吸汗性が望まれていた。
【０００６】
【発明が解決しようとする課題】
本発明は、前記従来技術の問題を解消するためになされたものであり、本発明の目的は、ソフトな風合い、吸汗性、耐摩耗性を有する低通気度織物を提供することにある。
【０００７】
【課題を解決するための手段】
本発明者は、フィラメントが特定のくびれ部を有する扁平断面糸であるマルチフィラメントを、経糸及び／又は緯糸として織物を構成することにより、マルチフィラメントが、織物組織点の接圧により緻密でワイドに広がった集合体となり、経糸と緯糸とで形成される空隙を小さくすることでき、その結果、優れたソフト性と低通気性を有する織物が得られること、また、かかる織物はくびれ部の毛細管現象で優れた吸汗性を有すること、さらには、該くびれ部によるフィラメント表面の凹凸により織物表面の摩擦抵抗が小さくなり、優れた耐摩耗性を有することを見出した。そして、さらに鋭意検討を重ねることにより、本発明を完成するに至った。
【０００８】
かくして、本発明によれば、「フィラメントの断面形状が３〜５個所のくびれ部を有する断面扁平度２〜６の扁平断面であるマルチフィラメント（Ａ）で、経糸および緯糸を構成してなる織物であって、前記マルチフィラメント（Ａ）が総繊度３０〜１７０ｄｔｅｘの無撚マルチフィラメントであり、かつカバーファクター（ＣＦ）が１５００〜３５００であることを特徴とする低通気度織物からなり、スポーツ衣料、ユニフォーム、紳士衣料品、婦人衣料品、インナー、裏地、帽子、傘地、トーブ、および民族衣装からなる群より選択されるいずれかの衣料関連商品。」が提供される。
【０００９】
その際、かかる低通気性としては、通気度で５ｃｃ／ｃｍ2・ｓｅｃ以下であることが好ましい。また、吸汗性としては４０ｍｍ以上であることが好ましい。さらに、耐摩耗性として１００回以上であることが好ましい。
【００１０】
【発明の実施の形態】
以下に本発明を詳細に説明する。
まず、本発明の低通気度織物の経糸又は緯糸を構成するマルチフィラメント（Ａ）は、繊維軸に対して直角方向の断面形状（横断面形状）が、２個所以上（好ましくは３〜５個所）のくびれ部を有する断面扁平度２〜６（好ましくは３〜５）のフィラメント（単糸）からなる。
【００１１】
ここで、断面扁平度とは、フィラメントの横断面において、長辺の長さ（Ｂ）と短辺の長さ（Ｃ）との比（Ｂ／Ｃ）である。該断面扁平度が２よりも小さいと、フィラメントの曲げ剛性が高くなるため、ソフトな風合いを得ることができず好ましくない。同時に、該断面扁平度が２よりも小さいと、織物中のマルチフィラメント（Ａ）が、ワイドに広がった集合形態を形成し難くなり、経糸と緯糸とで形成される空隙が大きくなり、十分な低通気性を得ることができず好ましくない。逆に、該断面扁平度が６を越えると、製糸性が困難となるため好ましくない。
【００１２】
次に、前記のくびれ部とは図１に模式的に示すように、短辺の長さ（Ｃ）が短くなっている部分のことである。かかるくびれ部において、凹部の深さとしては、短辺の長さ（Ｃ）の最大値と最小値の比（Ｃの最大／Ｃの最小）で１．０５以上（好ましくは１．１以上）となるような深さであることが好ましい。また、図１において、凹部が両側部に形成されているものを例示するが、一方の側部にのみ、凹部が形成されていてもよい。該くびれ部の個数は２個所以上である必要があり、くびれ部が１個所以下では、くびれ部において十分な毛細管現象が作用せず、満足な吸汗性が得られず好ましくない。また、同時にくびれ部が１個所以下では、フィラメント表面の凹凸が不十分であり、満足な耐摩耗性が得られず好ましくない。該くびれ部の個数は２個所以上であれば特に限定されないが、製糸性を考慮すると３〜５箇所が適当である。なお、図１は、くびれ部が３個所の場合を例示するものである。
【００１３】
マルチフィラメント（Ａ）の繊維種類としては特に限定されず、合成繊維、半合成繊維、天然繊維など公知の繊維でよい。なかでも、合成繊維が特に好ましく例示される。
【００１４】
かかる合成繊維としては、特に限定されないが、ポリエチレンテレフタレートやポリトリメチレンテレフタレートに代表されるポリエステル、ポリアミド、ポリ塩化ビニリデン、ポリプロピレンなどの合成繊維を使用することができる。なかでも、製造の容易さから、溶融紡糸で得られるポリエステル、ポリアミド、ポリ塩化ビニリデン、ポリプロピレンなどの合成繊維が好ましく例示される。
【００１５】
そして、マルチフィラメント（Ａ）には、必要に応じて、艶消し剤、微細孔形成剤、カチオン可染剤、着色防止剤、熱安定剤、難燃剤、蛍光増白剤、着色剤、帯電防止剤、吸湿剤、抗菌剤、無機微粒子等を１種又は２種以上を添加してもよい。
【００１６】
マルチフィラメント（Ａ）の繊維形態としては、特に限定されず、長繊維でも短繊維でもよい。なかでも、経糸と緯糸とで形成される空隙を小さくするために、無撚または甘撚りされた長繊維が好ましく例示される。特に、無撚の長繊維であることが特に好ましい。
【００１７】
該マルチフィラメント（Ａ）は、仮撚捲縮加工や、タスラン加工やインターレース加工などの空気加工が施されたものでもよい。
【００１８】
該マルチフィラメント（Ａ）の総繊度、単糸繊度については、特に限定されないが、風合いの点で、総繊度３０〜１７０ｄｔｅｘ（より好ましくは５０〜１００ｄｔｅｘ）、単糸繊度０．５〜５ｄｔｅｘ（より好ましくは１〜４ｄｔｅｘ）の範囲が適当である。
【００１９】
本発明の低通気度織物において、経糸または緯糸が、前記のマルチフィラメント（Ａ）で構成される。ここで、マルチフィラメント（Ａ）で経糸と緯糸を構成してもよいし、マルチフィラメント（Ａ）で、経糸と緯糸のどちらか一方を構成し、他方の糸として、制電糸などの機能糸を使用してもよい。また、マルチフィラメント（Ａ）で、経糸または緯糸を構成する際、本発明の目的を損なわない範囲内で少量、他の糸と混ぜ合わせてもよい。
【００２０】
次に、本発明の織物において、カバーファクター（ＣＦ）が１５００〜３５００（好ましくは１５００〜３０００、特に好ましく１５００〜２５００）である必要がある。
【００２１】
ここで、カバーファクター（ＣＦ）は表されるものである。
ＣＦ＝（ＤＷｐ／１．１）1/2×ＭＷｐ＋（ＤＷｆ／１．１）1/2×ＭＷｆ
ただし、ＤＷｐは経糸総繊度（ｄｔｅｘ）、ＭＷｐは経糸織密度（本／２．５４ｃｍ）、ＤＷｆは緯糸総繊度（ｄｔｅｘ）、ＭＷｆは緯糸織密度（本／２．５４ｃｍ）である。
【００２２】
該ＣＦが、１５００よりも小さいと、経糸と緯糸とで形成される空隙が大きくなり、十分な低通気性が得られず好ましくない。逆に、該ＣＦが３５００よりも大きいと、風合いのソフト性が低下するため好ましくない。
【００２３】
本発明の低通気度織物において、織組織は特に限定されず、平組織、綾組織、サテン組織など公知の織組織を使用することができる。なかでも、優れた低通気性を得る上で平組織が最も好ましい。
【００２４】
本発明の低通気度織物は、前記のマルチフィラメント（Ａ）を経糸及び／又は緯糸に用いて常法の製織方法で製織することができる。また、アルカリ減量加工や常法の染色仕上げ加工が施されてもよい。さらには、常法の吸水加工、撥水加工、起毛加工、さらには、紫外線遮蔽あるいは制電剤、抗菌剤、消臭剤、防虫剤、蓄光剤、再帰反射剤等の機能を付与する各種加工を付加適用してもよい。
【００２５】
このようにして得られた本発明の低通気度織物は、かかる低通気性としては、通気度で５ｃｃ／ｃｍ2・ｓｅｃ以下（より好ましくは２ｃｃ／ｃｍ2・ｓｅｃ以下）であることが好ましい。また、吸汗性としては４０ｍｍ以上（より好ましくは５０ｍｍ以上）であることが好ましい。さらに、耐摩耗性としては５０回以上（より好ましくは８０回以上、特に好ましくは１００回以上）であることが好ましい。
【００２６】
かかる低通気度織物は、前記のマルチフィラメント（Ａ）を経糸及び／又は緯糸に用いて、ＣＦの値を前記の範囲内で適宜選定することにより、容易に得られる。
【００２７】
本発明の低通気度織物において、マルチフィラメント（Ａ）を構成するフィラメントの横断面形状が扁平であるため、織物中において、マルチフィラメント（Ａ）は、織物組織点の接圧により、緻密かつワイドに広がった構造を有する。その結果、経糸と緯糸とで形成される空隙が小さくなり、通気を防止できるため、優れた低通気性を得ることができる。
【００２８】
同時に、マルチフィラメント（Ａ）がワイドに広がった構造を有する結果、曲げ剛性が低くなり、ソフトな風合いを得ることができる。その際、織物組織点において、くびれ部（凹部）は他方の糸に接触し難く経糸と緯糸との摩擦が小さくなり、フラットな扁平形状を有するものよりも、一層ソフトな風合いを得ることができる。
【００２９】
また、フィラメント表面の凹凸により、織物の表面摩擦抵抗が小さくなり、優れた耐摩耗性が得られる。
【００３０】
さらに、フィラメントのくびれ部に毛細官現象で水分が拡散されるため、優れた吸汗性が得られる。
【００３１】
本発明の低通気度織物は、前記のように、ソフトな風合い、吸汗性、耐摩耗性を有するため、スポーツ衣料、ユニフォーム、紳士、婦人、インナー、裏地等の衣料品、帽子、傘地等の繊維製品、トーブ等の民族衣装など各種の衣料関連商品に好適である。
【００３２】

BACKGROUND OF THE INVENTION
The present invention relates to a low air permeability fabric having excellent sweat absorption and abrasion resistance without impairing the soft texture.
[0002]
[Prior art]
Conventionally, many low-permeability fabrics have been proposed in the field of sports clothing and uniforms. As such a low air permeability fabric, a high-density fabric using a synthetic fiber such as polyester or polyamide, a fabric surface coated with a resin or the like, and a calendered fabric are also known. ing.
[0003]
However, these high-density woven fabrics, and those coated and calendered on the surface of the fabric, usually have a hard texture, and have low strength against abrasion (wear resistance) on the surface of the fabric. .
[0004]
On the other hand, a woven fabric made of synthetic fibers has a drawback that it is inferior in sweat absorption compared with a knitted fabric made of natural fibers such as cotton.
[0005]
As a method for imparting such sweat absorbency to a synthetic fiber, it is known to perform water absorption processing on a woven fabric using a hydrophilizing agent. However, depending on the application, more excellent sweat absorbency has been desired.
[0006]
[Problems to be solved by the invention]
The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a low air permeability fabric having a soft texture, sweat absorption and abrasion resistance.
[0007]
[Means for Solving the Problems]
The inventor configures a multifilament, which is a flat cross-sectional yarn having a specific constricted portion, as a warp and / or a weft so that the multifilament becomes dense and wide due to the contact pressure of the fabric texture point. It becomes an expanded assembly, and the gap formed between the warp and the weft can be reduced. As a result, a woven fabric having excellent softness and low air permeability can be obtained, and the woven fabric has a capillary phenomenon in the constricted portion. The present invention has been found to have excellent sweat-absorbing property, and furthermore, the frictional resistance of the fabric surface is reduced by the irregularities of the filament surface due to the constricted portion, and the wear resistance is excellent. Further, the present invention has been completed by further intensive studies.
[0008]
Thus, according to the present invention, "a woven fabric comprising warps and wefts with a multifilament (A) having a flat cross section with a flatness of 2 to 6 and having a constricted portion with 3 to 5 constricted sections. a is, the multi-filament (a) is untwisted multifilament total fineness 30～170Dtex, and the cover factor (CF) is a low air permeability fabrics, which is a 1500-3500, sportswear , Any clothing-related product selected from the group consisting of uniforms, men's clothing, women's clothing, inners, linings, hats, umbrellas, tobes, and national costumes .
[0009]
At that time, either as a hunt low air permeability, it is preferably not more than 5cc / cm 2 · sec in air permeability. Further, the sweat absorption is preferably 40 mm or more. Further, the wear resistance is preferably 100 times or more .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is described in detail below.
First, the multifilament (A) constituting the warp or weft of the low air permeability fabric of the present invention has two or more (preferably 3 to 5) cross-sectional shapes (cross-sectional shapes) perpendicular to the fiber axis. ) And a filament (single yarn) having a cross-sectional flatness of 2 to 6 (preferably 3 to 5).
[0011]
Here, the cross-sectional flatness is the ratio (B / C) of the length (B) of the long side and the length (C) of the short side in the cross section of the filament. When the cross-sectional flatness is less than 2, the bending rigidity of the filament is increased, and a soft texture cannot be obtained, which is not preferable. At the same time, if the cross-sectional flatness is smaller than 2, it becomes difficult for the multifilament (A) in the woven fabric to form a widened aggregated form, and the gap formed between the warp and the weft becomes large, and sufficient Low air permeability cannot be obtained, which is not preferable. On the contrary, when the cross-sectional flatness exceeds 6, it is not preferable because the yarn-making property becomes difficult.
[0012]
Next, the constricted portion is a portion where the short side length (C) is shortened, as schematically shown in FIG. In the constricted portion, the depth of the concave portion is 1.05 or more (preferably 1.1 or more) as a ratio of the maximum value and the minimum value of the short side length (C) (maximum of C / minimum of C). It is preferable that the depth be such that Moreover, in FIG. 1, although the thing in which the recessed part is formed in the both sides is illustrated, the recessed part may be formed only in one side part. The number of the constricted portions needs to be two or more, and if the number of constricted portions is one or less, sufficient capillary action does not act on the constricted portions, and satisfactory sweat absorption is not obtained. At the same time, if the number of constricted portions is one or less, irregularities on the filament surface are insufficient, and satisfactory wear resistance cannot be obtained, which is not preferable. The number of the constricted portions is not particularly limited as long as it is 2 or more, but 3 to 5 is appropriate in consideration of the yarn forming property. FIG. 1 illustrates the case where there are three constricted portions.
[0013]
The fiber type of the multifilament (A) is not particularly limited, and may be a known fiber such as a synthetic fiber, a semi-synthetic fiber, or a natural fiber. Of these, synthetic fibers are particularly preferred.
[0014]
Such a synthetic fiber is not particularly limited, and synthetic fibers such as polyester, polyamide, polyvinylidene chloride, and polypropylene represented by polyethylene terephthalate and polytrimethylene terephthalate can be used. Of these, synthetic fibers such as polyester, polyamide, polyvinylidene chloride, and polypropylene obtained by melt spinning are preferred because of their ease of production.
[0015]
For the multifilament (A), a matting agent, a fine pore forming agent, a cationic dyeing agent, a coloring inhibitor, a heat stabilizer, a flame retardant, a fluorescent brightening agent, a coloring agent, and an antistatic agent, as necessary. One or more agents, hygroscopic agents, antibacterial agents, inorganic fine particles and the like may be added.
[0016]
The fiber form of the multifilament (A) is not particularly limited, and may be long fibers or short fibers. Especially, in order to make small the space | gap formed with a warp and a weft, the non-twisted or sweet twisted long fiber is illustrated preferably. In particular, untwisted long fibers are particularly preferable.
[0017]
The multifilament (A) may be subjected to air twisting such as false twist crimping, taslan processing or interlace processing.
[0018]
The total fineness and single yarn fineness of the multifilament (A) are not particularly limited, but in terms of texture, the total fineness is 30 to 170 dtex (more preferably 50 to 100 dtex), and the single yarn fineness is 0.5 to 5 dtex (more The range of 1 to 4 dtex) is suitable.
[0019]
In the low air permeability fabric of the present invention, the warp or the weft is composed of the multifilament (A). Here, the warp and the weft may be constituted by the multifilament (A), or one of the warp and the weft is constituted by the multifilament (A), and the function yarn such as the antistatic yarn is used as the other yarn. May be used. Further, when the warp or weft is constituted by the multifilament (A), a small amount may be mixed with other yarns within the range not impairing the object of the present invention.
[0020]
Next, in the woven fabric of the present invention, the cover factor (CF) needs to be 1500 to 3500 (preferably 1500 to 3000, particularly preferably 1500 to 2500).
[0021]
Here, the cover factor (CF) is expressed.
CF = (DWp / 1.1) 1/2 × MWp + (DWf / 1.1) 1/2 × MWf
However, DWp is the total warp fineness (dtex), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (dtex), and MWf is the weft weave density (main / 2.54 cm).
[0022]
When the CF is smaller than 1500, the gap formed between the warp and the weft becomes large, and a sufficiently low air permeability cannot be obtained. On the contrary, if the CF is larger than 3500, the softness of the texture is lowered, which is not preferable.
[0023]
In the low air permeability fabric of the present invention, the woven structure is not particularly limited, and a known woven structure such as a plain structure, a twill structure, and a satin structure can be used. Of these, a flat structure is most preferable for obtaining excellent low air permeability.
[0024]
The low air permeability fabric of the present invention can be woven by a conventional weaving method using the multifilament (A) as warp and / or weft. Alkali weight loss processing and conventional dyeing finishing processing may be performed. Furthermore, conventional water-absorbing processing, water-repellent processing, brushed processing, and various processing that provides functions such as UV shielding or antistatic agents, antibacterial agents, deodorants, insect repellents, phosphorescent agents, and retroreflective agents May be additionally applied.
[0025]
Low air permeability fabrics of the present invention obtained in this way, as such a low air permeability, you are preferable that 5cc / cm 2 · sec or less air permeability (more preferably 2cc / cm 2 · sec or less) . Further, the sweat absorption is preferably 40 mm or more (more preferably 50 mm or more). Further, the wear resistance is preferably 50 times or more (more preferably 80 times or more, particularly preferably 100 times or more).
[0026]
Such a low air permeability woven fabric can be easily obtained by using the multifilament (A) for warp and / or weft and appropriately selecting the CF value within the above range.
[0027]
In the low air permeability fabric of the present invention, since the cross-sectional shape of the filament constituting the multifilament (A) is flat, in the fabric, the multifilament (A) is dense and wide due to the contact pressure of the fabric texture point. It has a structure spread out. As a result, the gap formed between the warp and the weft is reduced, and ventilation can be prevented, so that excellent low air permeability can be obtained.
[0028]
At the same time, as a result of the multifilament (A) having a wide structure, the bending rigidity is lowered and a soft texture can be obtained. At that time, at the woven fabric structure point, the constricted portion (concave portion) is difficult to contact the other yarn, the friction between the warp and the weft is reduced, and a softer texture than that having a flat flat shape can be obtained. .
[0029]
In addition, the unevenness of the filament surface reduces the surface frictional resistance of the fabric and provides excellent wear resistance.
[0030]
Furthermore, since moisture is diffused by a capillary phenomenon in the constricted portion of the filament, excellent sweat absorption is obtained.
[0031]
As described above, the low-breathing fabric of the present invention has a soft texture, sweat absorption, and wear resistance. Therefore, sports clothing, uniforms, gentlemen, ladies, inners, linings and other clothing items, hats, umbrellas, etc. It is suitable for various clothing-related products such as textile products and folk costumes such as toves.
[0032]
