The form of the fiber fabric may be any form such as a woven fabric, a knitted fabric, or a non-woven fabric.
Also, textile fabrics can be dyed, printed, water-repellent, antistatic, water-absorbing, SR processed, antibacterial and deodorant, antibacterial, deodorant, ultraviolet shielding, flameproof, and calendered You may give it.
伸び率の観点からは、ポリウレタン繊維やポリトリメチレンテレフタレートなどの伸縮性の素材を用いた繊維布帛やかさ高加工などの伸縮性を付与することができる加工がなされた加工糸を用いた織物、編物などが好ましい。また、これらのものを組み合わせたものであってもよい。 From the standpoint of elongation, fabrics and knitted fabrics using processed yarns that have been processed to give elasticity such as fiber fabrics using bulky materials such as polyurethane fibers and polytrimethylene terephthalate, and bulky processing Etc. are preferable. A combination of these may also be used.
繊維布帛は、タテ方向またはヨコ方向の少なくともいずれか一方の伸び率は３０％以上有するとよい。より好ましくは５０％がよい。伸び率の上限は特にないが、本発明の繊維布帛を用いて製造される繊維製品の特性に応じ決定すればよい。
この場合の伸び率はＪＩＳ Ｌ１０９６ 伸縮織物及び編物の伸縮性 伸び率 Ａ法（定速伸長法）で測定したものをいう。
The fiber fabric preferably has an elongation percentage of at least one of the vertical direction and the horizontal direction of 30% or more. More preferably, 50% is good. There is no particular upper limit for the elongation, but it may be determined according to the characteristics of the fiber product produced using the fiber fabric of the present invention.
The elongation rate in this case refers to that measured by the JIS L1096 stretch fabric and knitted fabric stretch elongation rate A method (constant speed stretch method).
本発明の凹凸のある樹脂膜の素材としては、ポリウレタン、アクリル、ポリエステル、ナイロン、ポリテトラフルオロエチレン、塩化ビニルなどがあげられる。特に、伸縮性を有するポリウレタンが好ましい。また、ウレタン樹脂は透湿性を有しているものであっても、有していないものであってもいずれでも使用することができる。 Examples of the material for the uneven resin film of the present invention include polyurethane, acrylic, polyester, nylon, polytetrafluoroethylene, and vinyl chloride.

If it is less than 5 micrometers, there exists a possibility that the increase in the air permeability when extending | stretching a breathable fabric cannot be suppressed. On the other hand, if it exceeds 100 μm, the texture of the resulting breathable fabric may become hard, although it depends on the balance of the unevenness.
また、凹凸のある樹脂膜の凹部、つまり樹脂膜の薄い部分の膜の厚みは、１μｍ〜３０μｍがよい。１μｍ未満では、伸長時の通気度の増加を抑制できなくなるおそれがある。３０μｍを超えると風合いが硬くなるおそれがある。
また、凹凸のある樹脂膜の凸部、つまり樹脂膜の厚い部分の膜の厚みは、１０〜１００μｍがよい。１０μｍ未満であると凸部に貫通孔が形成されないおそれがある。１００μｍを超えると、凹凸のバランスにもよるが、得られる通気性布帛の風合いが硬くなるおそれがある。
Moreover, the thickness of the concave portion of the resin film having unevenness, that is, the thickness of the thin portion of the resin film is preferably 1 μm to 30 μm. If it is less than 1 μm, an increase in air permeability during elongation may not be suppressed. If it exceeds 30 μm, the texture may become hard.
Further, the thickness of the convex portion of the resin film with unevenness, that is, the thickness of the thick part of the resin film is preferably 10 to 100 μm. If it is less than 10 μm, there is a possibility that no through hole is formed in the convex portion. If it exceeds 100 μm, the texture of the resulting breathable fabric may become hard, although it depends on the balance of the unevenness.
本発明の前記凹凸のある樹脂膜の凸部には貫通孔を有する。一般的に繊維布帛に樹脂膜を付与し、孔を設けることにより通気性を付与する場合には、多数の孔が連通した多孔質の樹脂膜や均一な厚みの膜に針などのより貫通孔を開ける方法や凹凸のある樹脂膜の場合には凹部に孔を設けるものが考えられるが、本発明では樹脂膜の凸部に貫通孔を有する。なお、凹凸を有する樹脂膜の全ての凸部に貫通孔を有している必要はない。１ｍｍ２あたり１〜５０個の貫通孔を有するとよい。 The convex portion of the uneven resin film of the present invention has a through hole. In general, when a resin film is provided on a fiber fabric and air permeability is provided by providing holes, a porous resin film in which a large number of holes communicate with each other and a film having a uniform thickness, such as a needle or the like. In the case of a resin film having an unevenness or a resin film having irregularities, it is conceivable to provide a hole in the concave portion. Note that it is not necessary to have through holes in all the convex portions of the resin film having irregularities. It may have a 1 mm 2 per 1-50 of the through hole.
本発明では、凸部に貫通孔を有することにより、通気性布帛を伸長させたとき、また、洗濯後に通気性布帛を伸長させたときの通気度の増加を抑制することができる。
凸部は、膜の厚みが厚くなっており、そこに貫通孔が形成された場合、貫通孔の周りの樹脂の厚みが厚くなっている。
このような構成とすることにより、通気性を有し、かつ、伸長時、貫通孔は回りに存在する樹脂により引き伸ばされることが抑制され、凹部の薄い樹脂膜の方が引き伸ばされることで、通気度の増加を抑制していると考えている。
また、洗濯時においても貫通孔の周りの樹脂が磨耗による貫通孔の拡大を抑制し、洗濯処理後においても伸長時の通気度の増加を抑制していると考えている。
In the present invention, by having the through hole in the convex portion, it is possible to suppress an increase in air permeability when the breathable fabric is stretched or when the breathable fabric is stretched after washing.
The convex portion has a thick film, and when a through hole is formed there, the resin around the through hole is thick.
By adopting such a configuration, it has air permeability, and when it is extended, the through hole is suppressed from being stretched by the resin existing around it, and the resin film with a thinner recess is stretched, thereby I think that the increase of the degree is suppressed.
In addition, it is considered that the resin around the through-hole suppresses the expansion of the through-hole due to wear even during washing, and suppresses an increase in air permeability during elongation even after the washing process.
また、貫通孔の周りにある凸部および貫通孔のない凸部は、樹脂が充填されているものであっても、また、空洞であってもよい。 Moreover, the convex part around the through hole and the convex part without the through hole may be filled with resin or may be hollow.
また、本発明では前記貫通孔の大きさが１〜３００μｍであるとよい。３００μｍを超えると防風性や羽毛などの飛び出しを抑制する効果が低下するおそれがあり、１μｍ未満では、十分な通気性が得られないおそれがある。 In the present invention, the size of the through hole is preferably 1 to 300 μm. If it exceeds 300 μm, the windproof property and the effect of suppressing the jumping out of feathers and the like may be reduced, and if it is less than 1 μm, sufficient air permeability may not be obtained.
また、本発明の通気性布帛は、３０％伸長させたときの通気度の増加が未伸長時の３倍以下であるとよい。
３０％伸長させたときの通気度の増加が未伸長時の３倍以下であれば、衣服として繊維布帛を用いた場合に、実着用時に衣服一部が伸長されていたとしても防風性を維持し、防寒性が大きく低下することを防ぐ。
より好ましくは５０％伸長させたときの通気度の増加が未伸長時の３倍以下であるとよい。
In addition, the breathable fabric of the present invention may have an increase in air permeability when stretched by 30% is 3 times or less of that when not stretched.
If the increase in air permeability when stretched by 30% is less than 3 times that when unstretched, the use of fiber cloth as clothing will maintain windproof properties even if the clothing is partially stretched during actual wearing. And prevent the cold resistance from greatly deteriorating.
More preferably, the increase in air permeability when stretched 50% is not more than 3 times that when unstretched.
通気度は、未伸長時、伸長時とも、５ｃｍ３／ｃｍ２・ｓ以下、より好ましくは２ｃｍ３／ｃｍ２・ｓ以下がよい。
５ｃｍ３／ｃｍ２・ｓを超えると十分な防風性やダウンなどの飛び出し防止性が十分ではないおそれがある。
Air permeability, when not extended, both during extension, 5cm 3 / cm 2 · s or less, and more preferably 2cm 3 / cm 2 · s or less.
If it exceeds 5 cm 3 / cm 2 · s, there is a possibility that sufficient windproof properties and anti-projection properties such as down may not be sufficient.
なお、３０％伸長させたときの通気度の測定は、通気性布帛のタテ方向またはヨコ方向のいずれか一方を伸長前の長さから３０％引伸ばし、通気度を測定する。
通気度の測定は、ＪＩＳ Ｌ１０９６Ａ法（フラジール形法）に準じて測定する。
In addition, the measurement of the air permeability when stretched by 30% is performed by stretching either one of the vertical direction or the horizontal direction of the breathable fabric by 30% from the length before stretching, and measuring the air permeability.
The air permeability is measured according to JIS L1096A method (Fragile type method).
洗濯２０回後においても、３０％伸長させたときの通気度の増加が未伸長時の３倍以下であるとよい。より好ましくは５０％伸長させたときの通気度の増加が未伸長時の３倍以下であるとよい。
なお、洗濯方法はＪＩＳ Ｌ０２１７ １０３法に準じた方法で行ったものである。
Even after 20 washings, the increase in air permeability when stretched 30% is preferably 3 times or less that when unstretched. More preferably, the increase in air permeability when stretched 50% is not more than 3 times that when unstretched.
In addition, the washing method was performed by the method according to JIS L0217 103 method.
また、本発明の通気性布帛は、タテ方向またはヨコ方向の少なくともいずれか一方の伸び率は３０％以上有するとよい。より好ましくは５０％がよい。伸び率の上限は特にないが、本発明の繊維布帛を用いて製造される繊維製品の特性に応じ決定すればよい。
この場合の伸び率はＪＩＳ Ｌ１０９６ 伸縮織物及び編物の伸縮性 伸び率 Ａ法（定速伸長法）で測定したものをいう。
Moreover, the breathable fabric of this invention is good to have 30% or more of elongation rate of at least any one of a length direction or a horizontal direction. More preferably, 50% is good. There is no particular upper limit for the elongation, but it may be determined according to the characteristics of the fiber product produced using the fiber fabric of the present invention.
The elongation rate in this case refers to that measured by the JIS L1096 stretch fabric and knitted fabric stretch elongation rate A method (constant speed stretch method).

And a resin film having an uneven surface.
性能の安定性の観点からは接着剤によって貼り合せたものが好ましく、繊維布帛と凹凸のある樹脂膜は、点状、線状、格子状等に用いられた接着剤によって、接着されているものが通気度を出す観点より好ましい。接着剤が繊維布帛と凹凸のある樹脂膜の全面に隙間無く覆うように用いられると、貫通孔が接着剤で埋まってしまい、通気度が大きく低下するおそれがある。より高い通気性を付与するとの観点からは点状に接着剤を用いるとよい。 From the viewpoint of stability of performance, those bonded with an adhesive are preferable, and the fiber fabric and the resin film with projections and depressions are bonded with an adhesive used in the form of dots, lines, lattices, etc. Is preferable from the viewpoint of obtaining air permeability. If the adhesive is used so as to cover the entire surface of the fiber fabric and the uneven resin film without a gap, the through hole is filled with the adhesive, and the air permeability may be greatly reduced. From the viewpoint of imparting higher air permeability, an adhesive may be used in the form of dots.
以上のような本発明の構成を有することにより、樹脂膜を付与された布帛が伸長された場合にも、通気度が大きく低下することを防ぎ、また、洗濯処理後においてもこれらの性質の低下を防ぐことができる。 By having the structure of the present invention as described above, even when the fabric to which the resin film is applied is stretched, the air permeability is prevented from being greatly reduced, and these properties are reduced even after the washing treatment.

次の下記樹脂溶液をナイフコータを用い（スリット０．０６ｍｍ）て繊維布帛の片面に塗布し、１１０℃にて乾燥し、引き続き、１７０℃にて仕上げセットをおこない繊維布帛の片面に樹脂膜を付与し、通気性布帛を得た。得られた通気性繊維布帛は樹脂が繊維布帛の繊維と繊維の間に入り込み繊維と繊維の隙間を埋めていた。得られた通気性布帛の性能を以下に記載した。このような通気性繊維布帛は、伸長により繊維と繊維の間の樹脂が繊維から剥がれたり、樹脂が裂けたりすることにより通気性が増加すると考えられる。 The following resin solution is applied to one side of the fiber fabric using a knife coater (slit 0.06 mm), dried at 110 ° C., and then finish-set at 170 ° C. to give a resin film to one side of the fiber fabric. As a result, a breathable fabric was obtained. In the obtained breathable fiber fabric, the resin entered between the fibers of the fiber fabric and filled the gap between the fibers. The performance of the obtained breathable fabric was described below. Such a breathable fiber fabric is considered to increase the breathability when the resin between the fibers is peeled off from the fibers due to elongation or the resin is torn.
