Abstract
Description
本発明は、防風性生地及び衣服に関する。 The present invention relates to windproof fabrics and garments.
繊維生地を衣服として用いる際、体温の損失を予防し、防寒性を向上させることを目的として、繊維生地に樹脂を含浸させたり、繊維生地に合成樹脂からなる樹脂膜を積層させたりした防風性生地が広く使用されている。
例えば特許文献１には、編地の片面に樹脂コーティングが施されている防風性肌着が開示されている。
When the fiber fabric is used as clothing, it has windproof properties such as impregnating the fiber fabric with resin or laminating a resin film made of synthetic resin on the fiber fabric for the purpose of preventing loss of body temperature and improving cold protection. The fabric is widely used.
For example, Patent Document 1 discloses a windproof underwear in which one side of a knitted fabric is coated with a resin.
また、着用者の快適性の観点から、繊維生地には、雨などの水分により衣服の表面が湿潤してしまうことを防ぐための撥水性能や、不感蒸泄や発汗などによる衣服内のムレを防ぐための透湿性能が求められている。
例えば繊維生地に撥水性能を付与するには、撥水剤を用いればよい。
In addition, from the viewpoint of wearer's comfort, the fiber fabric has water-repellent performance to prevent the surface of the clothes from getting wet due to moisture such as rain, and stuffiness in the clothes due to insensitive evaporation and sweating. Moisture permeability is required to prevent this.
For example, in order to impart water repellency to the fiber fabric, a water repellent agent may be used.
近年、環境への関心が高まり、低環境負荷の素材を求められるようになっている。特に撥水剤において、炭素数が８のパーフルオロアルキル基を有するフッ素系撥水剤（Ｃ８フッ素系撥水剤）などは、環境への悪影響が懸念されるパーフルオロオクタン酸が含まれていると言われている。そこで、炭素数が６のパーフルオロアルキル基を有するフッ素系撥水剤（Ｃ６フッ素系撥水剤）や、フッ素を含まない撥水剤（非フッ素系撥水剤）などへの切り替えが求められている。
例えば特許文献２には、織編物の一方の面にポリウレタン等で形成された透湿防水層（親水性の樹脂膜）を有し、織編物の他方の面に炭素数が１〜６のパーフルオロアルキル基を有する撥水剤又は非フッ素系撥水剤が付着した、撥水性及び透湿防水性を有する積層生地が開示されている。
In recent years, there has been increasing interest in the environment, and there is a growing demand for materials with a low environmental load. In particular, among water repellents, fluorine-based water repellents having a perfluoroalkyl group having 8 carbon atoms (C8 fluorine-based water repellent) and the like contain perfluorooctanoic acid, which may have an adverse effect on the environment. Is said to be. Therefore, it is required to switch to a fluorine-based water repellent having a perfluoroalkyl group having 6 carbon atoms (C6 fluorine-based water repellent) or a fluorine-free water repellent (non-fluorine-based water repellent). ing.
For example, Patent Document 2 has a moisture-permeable waterproof layer (hydrophilic resin film) formed of polyurethane or the like on one surface of a woven or knitted fabric, and a par with 1 to 6 carbon atoms on the other surface of the woven or knitted fabric. A laminated fabric having water repellency and moisture permeability and waterproofness to which a water repellent having a fluoroalkyl group or a non-fluorophilic water repellent is attached is disclosed.
しかしながら、Ｃ８フッ素系撥水剤などと比較して、Ｃ６フッ素系撥水剤や非フッ素系撥水剤などは撥水性能が低い傾向にある。特に特許文献２に記載の積層生地のように、繊維生地の一方の面に親水性の樹脂膜（親水性膜）が積層され、他方の面に撥水剤が付着している防風性生地では、繊維生地の他方の面に接触した水分が、繊維生地の一方の面に積層された親水性膜の作用によって吸引され、撥水性が低下するという課題がある。
特許文献２に記載の積層生地では、織編物の表面形状やカバーファクターを規定することにより撥水性能を向上させているが、平凡で安価な繊維生地ではなく特殊な織編物に限定されてしまう。そのため、伸縮性を有し頻繁に目開きが発生する繊維生地や、軽量化や風合いのソフト化のために細い糸や密度の低い繊維生地などには適用するのは困難である。
However, the water repellency of C6 fluorine-based water repellent and non-fluorine-based water repellent tends to be lower than that of C8 fluorine-based water repellent. In particular, in a windproof fabric such as the laminated fabric described in Patent Document 2, a hydrophilic resin film (hydrophilic film) is laminated on one surface of the fiber fabric and a water repellent agent is adhered to the other surface. There is a problem that water in contact with the other surface of the fiber fabric is sucked by the action of the hydrophilic film laminated on one surface of the fiber fabric, and the water repellency is lowered.
In the laminated fabric described in Patent Document 2, the water repellency is improved by defining the surface shape and the cover factor of the woven or knitted fabric, but it is limited to a special woven or knitted fabric rather than a mediocre and inexpensive fiber fabric. .. Therefore, it is difficult to apply it to a fiber fabric having elasticity and frequently opening, a fine thread or a fiber fabric having a low density for weight reduction and softening of texture.
本発明は、低環境負荷でありながら、優れた防風性、透湿性及び撥水性を有する防風性生地及び衣服を提供することを目的とする。 An object of the present invention is to provide a windproof fabric and garment having excellent windproofness, moisture permeability and water repellency while having a low environmental load.

なお、本発明においては、糸に撥水剤や第４族元素化合物が練り込まれたものは、繊維表面に付着しているとはみなさない。
A water repellent agent having no perfluoroalkyl group having 7 or more carbon atoms and a group 4 element compound are attached to the fiber surface of the fiber fabric.
In the present invention, a yarn kneaded with a water repellent or a Group 4 element compound is not considered to be attached to the fiber surface.
防風性生地の主たる撥水性は、炭素数７以上のパーフルオロアルキル基を有しない撥水剤が担う。
炭素数７以上のパーフルオロアルキル基を有しない撥水剤は、低環境負荷の素材である。このような撥水剤としては、炭素数１〜６のパーフルオロアルキル基を有するフッ素化合物からなるフッ素系撥水剤や、フッ素を含まない撥水剤（非フッ素系撥水剤）などが挙げられる。
フッ素系撥水剤としては、パーフルオロヘキサン酸やそれら由来のユニットを側鎖に持つ重合体等のＣ６フッ素系撥水剤などが挙げられる。
非フッ素系撥水剤としては、炭化水素化合物（例えば脂肪族系炭化水素、脂肪族カルボン酸、ポリ（メタ）アクリル酸エステル等）、シリコーン系化合物などが挙げられる。
炭素数７以上のパーフルオロアルキル基を有しない撥水剤は、１種を単独で使用してもよく、２種以上を併用してもよい。
The main water repellency of the windproof fabric is borne by the water repellent agent having 7 or more carbon atoms and having no perfluoroalkyl group.
A water repellent agent having no perfluoroalkyl group having 7 or more carbon atoms is a material having a low environmental load. Examples of such a water repellent include a fluorine-based water repellent composed of a fluorine compound having a perfluoroalkyl group having 1 to 6 carbon atoms, a fluorine-free water repellent (non-fluorine water repellent), and the like. Be done.
Examples of the fluorine-based water repellent include C6 fluorine-based water repellent such as perfluorocaproic acid and a polymer having a unit derived from them in the side chain.
Examples of the non-fluorine-based water repellent include hydrocarbon compounds (for example, aliphatic hydrocarbons, aliphatic carboxylic acids, poly (meth) acrylic acid esters, etc.), silicone-based compounds, and the like.
As the water repellent having no perfluoroalkyl group having 7 or more carbon atoms, one type may be used alone or two or more types may be used in combination.
炭素数７以上のパーフルオロアルキル基を有しない撥水剤は、繊維表面に、防風性生地１ｍ２あたり０．０１〜１０ｇ付着していることが好ましく、より好ましは０．０５〜５ｇであり、さらに好ましくは０．１〜３ｇであり、特に好ましくは０．５〜１．５ｇである。防風性生地１ｍ２あたりの付着量が上記下限値以上であれば、撥水性を充分に発現できる。防風性生地１ｍ２あたりの付着量が上記上限値以下であれば、充分な引裂強力や縫目強力が得られやすくなる。加えて、チョークマークの発生を抑制できる。 The water repellent having no perfluoroalkyl group having 7 or more carbon atoms preferably adheres to the fiber surface in an amount of 0.01 to 10 g per 1 m 2 of the windproof fabric, more preferably 0.05 to 5 g. It is more preferably 0.1 to 3 g, and particularly preferably 0.5 to 1.5 g. When the amount of adhesion per 1 m 2 of the windproof fabric is at least the above lower limit value, water repellency can be sufficiently exhibited. When the amount of adhesion per 1 m 2 of the windproof fabric is not more than the above upper limit value, sufficient tear strength and stitch strength can be easily obtained. In addition, the generation of chalk marks can be suppressed.
第４族元素化合物の性質は完全には解明されていないが、第４族元素化合物は、未反応の化合物の状態では親水性の官能基と高い親和性を有するが、熱処理等が施されることで第４族元素を中心金属とし、親水性官能基を配位子として配位結合し、配位子を介して水に不溶の架橋構造を形成し、水の吸引を抑制するものと考えられる。このような性質を有する第４族元素化合物が撥水剤に対し補助的に作用することにより、第１の面に後述の親水性膜が積層されている繊維生地、特に伸縮性を有し頻繁に目開きが発生する繊維生地や、細い糸や密度の低い繊維生地などであっても、優れた撥水性を発現できる。
なお、繊維生地の艶消しなどを目的として第４族元素化合物を糸に練り込んだ繊維生地が知られているが、糸中に存在する第４族元素化合物では上述した架橋構造が形成されにくい。架橋構造を形成するためには、第４族元素化合物が繊維の表面に付着している必要がある。
Although the properties of the Group 4 element compound have not been completely elucidated, the Group 4 element compound has a high affinity with the hydrophilic functional group in the state of the unreacted compound, but is subjected to heat treatment or the like. Therefore, it is considered that the group 4 element is used as the central metal and the hydrophilic functional group is coordinated and bonded as the ligand to form a water-insoluble bridge structure via the ligand and suppress the suction of water. Be done. The group 4 element compound having such properties acts as an auxiliary action on the water repellent, so that the fiber fabric in which the hydrophilic film described later is laminated on the first surface, particularly elastic and frequently Excellent water repellency can be exhibited even in a fiber fabric having an opening, a fine thread, or a fiber fabric having a low density.
A fiber fabric in which a Group 4 element compound is kneaded into a yarn is known for the purpose of matting the fiber fabric, but the above-mentioned crosslinked structure is difficult to be formed with the Group 4 element compound present in the yarn. .. In order to form a crosslinked structure, the Group 4 element compound needs to be attached to the surface of the fiber.
第４族元素化合物としては、配位子を介して架橋構造を形成するものが挙げられ、具体的には、酢酸ジルコニウム等の塩、炭酸ジルコニウムアンモニウム等の複塩、塩化ジルコニウム（IV）等のハロゲン化物、酸化チタン（IV）等の酸化物、チタンやジルコニウムを中心金属に持つカルボニル錯体、アミド錯体、メタロセン錯体、アルコキシドやアセチルアセトネートやトリエタノールアミネート等との有機金属化合物などが挙げられる。
なお、第４族元素化合物の中には半導体として光触媒活性を有するものも存在するが、光触媒の作用により親水化や架橋構造の不安定化の原因となることがある。そのため、第４族元素化合物が光触媒活性を有する場合は、結晶構造を変えたり、表面を被覆したりするなどして、光触媒活性を事実上無視できる程度まで低下させておくことが好ましい。
第４族元素化合物は、１種を単独で使用してもよく、２種以上を併用してもよい。
Examples of the Group 4 element compound include those forming a crosslinked structure via a ligand, and specifically, a salt such as zirconium acetate, a compound salt such as ammonium zirconium carbonate, zirconium chloride (IV) and the like. Examples thereof include halides, oxides such as titanium oxide (IV), carbonyl complexes having titanium or zirconium as a central metal, amide complexes, metallocene complexes, and organic metal compounds with alkoxides, acetylacetonates, triethanolaminets and the like. ..
Although some Group 4 element compounds have photocatalytic activity as semiconductors, they may cause hydrophilization and destabilization of the crosslinked structure due to the action of the photocatalyst. Therefore, when the Group 4 element compound has photocatalytic activity, it is preferable to reduce the photocatalytic activity to a practically negligible level by changing the crystal structure or coating the surface.
As the Group 4 element compound, one kind may be used alone, or two or more kinds may be used in combination.
第４族元素化合物は、繊維表面に、防風性生地１ｍ２あたり０．１ｇ以上付着していることが好ましく、より好ましは０．５ｇ以上であり、さらに好ましくは１ｇ以上である。防風性生地１ｍ２あたりの付着量が上記下限値以上であれば、撥水剤に対する補助作用が発現しやすくなり、防風性生地に優れた撥水性を付与しやすい。
第４族元素化合物の付着量の上限値については特に限定されないが、防風性生地１ｍ２あたり２０ｇを超えて第４族元素化合物が付着していると、風合いがハードになるおそれがある。よって、第４族元素化合物の付着量は、防風性生地１ｍ２あたり２０ｇ以下が好ましく、１５ｇ以下がより好ましい。
The Group 4 element compound preferably adheres to the fiber surface in an amount of 0.1 g or more per 1 m 2 of the windproof fabric, more preferably 0.5 g or more, and further preferably 1 g or more. When the amount of adhesion per 1 m 2 of the windproof fabric is at least the above lower limit value, the auxiliary action on the water repellent agent is likely to be exhibited, and it is easy to impart excellent water repellency to the windproof fabric.
The upper limit of the amount of the Group 4 element compound attached is not particularly limited, but if the Group 4 element compound adheres in excess of 20 g per 1 m 2 of the windbreaker fabric, the texture may become hard. Therefore, the amount of the Group 4 element compound adhered is preferably 20 g or less, more preferably 15 g or less per 1 m 2 of the windproof dough.
繊維生地は、織物（布帛）、編物（ニット）、不織布など、いかなる形態であってもよいが、織物又は編物であることが特に好ましい。また、伸縮性のある弾性糸を用いたり編物としたりして、伸縮性を与えて着用感を改善させた繊維生地を用いてもよい。 The fibrous fabric may be in any form such as a woven fabric (fabric), a knitted fabric (knit), and a non-woven fabric, but a woven fabric or a knitted fabric is particularly preferable. Further, a fiber fabric having elasticity may be used or a knitted fabric may be used to improve the wearing feeling.
繊維生地が織物である場合、カバーファクターについては特に限定されない。軽量化や風合いのソフト化の観点ではカバーファクターは低い方が好ましく、具体的には、カバーファクターは９００以上１８００未満が好ましく、１１００以上１６００未満がより好ましい。カバーファクターが上記範囲内であれば、防風性生地を衣服として実用する際の強度を維持しつつ、軽量化や風合いのソフト化を達成できる。
なお、カバーファクターは下記式（ｉ）で算出される、織物の粗密を数値化したものである。
ＣＦ＝Ｔ×（ＤＴ）１／２＋Ｗ×（ＤＷ）１／２ ・・・（ｉ）
（式（ｉ）中、「ＣＦ」はカバーファクターであり、「Ｔ」は織物を構成する経糸の密度（本／２．５４ｃｍ）であり、「Ｗ」は織物を構成する緯糸の密度（本／２．５４ｃｍ）であり、「ＤＴ」は織物を構成する経糸の繊維太さ（ｄｔｅｘ）であり、「ＤＷ」は織物を構成する緯糸の繊維太さ（ｄｔｅｘ）である。）
When the fiber fabric is a woven fabric, the cover factor is not particularly limited. From the viewpoint of weight reduction and softening of texture, it is preferable that the cover factor is low, and specifically, the cover factor is preferably 900 or more and less than 1800, and more preferably 1100 or more and less than 1600. If the cover factor is within the above range, it is possible to achieve weight reduction and soft texture while maintaining the strength when the windproof fabric is practically used as clothing.
The cover factor is a numerical value of the roughness of the woven fabric calculated by the following formula (i).
CF = T × (DT) 1/2 + W × (DW) 1/2 ... (i)
(In formula (i), "CF" is the cover factor, "T" is the density of the warp threads constituting the woven fabric (book / 2.54 cm), and "W" is the density of the weft threads constituting the woven fabric (book). /2.54 cm), where "DT" is the fiber thickness (dtex) of the warp threads constituting the woven fabric, and "DW" is the fiber thickness (dtex) of the weft threads constituting the woven fabric.
繊維生地が編物である場合、編物を構成する繊維の太さやゲージについては特に限定されない。軽量化や風合いのソフト化の観点では繊維太さやゲージは小さい方が好ましく、具体的には、繊維太さ（ｄｔｅｘ）と２．５４ｃｍあたりのゲージ数の積は６５０以上１８００未満が好ましく、８５０以上１６００未満がより好ましい。繊維太さ（ｄｔｅｘ）と２．５４ｃｍあたりのゲージ数の積が上記範囲内であれば、防風性生地を衣服として実用する際の強度を維持しつつ、軽量化や風合いのソフト化を達成できる。 When the fiber fabric is a knit, the thickness and gauge of the fibers constituting the knit are not particularly limited. From the viewpoint of weight reduction and softening of texture, it is preferable that the fiber thickness and gauge are small. Specifically, the product of the fiber thickness (dtex) and the number of gauges per 2.54 cm is preferably 650 or more and less than 1800, and 850. More than 1600 is more preferable. If the product of the fiber thickness (dtex) and the number of gauges per 2.54 cm is within the above range, it is possible to achieve weight reduction and soft texture while maintaining the strength when the windproof fabric is practically used as clothing. ..
繊維生地は、予め着色されていてもよいし、着色されていなくてもよい。繊維生地を予め着色する場合には、分散染料、カチオン染料、酸性染料、直接染料、反応染料、建染染料、硫化染料等の染料、蛍光増白剤、又は顔料などを用いて繊維生地を着色することができる。
また、酸性染料を用いてナイロンを染色する場合に実施される合成タンニン等を用いたフィックス処理など、通常の繊維の着色時に行われている各種処理を行ってもよい。
繊維の着色方法としては特に限定されず、例えば原着、浸染、捺染などの方法が挙げられる。
なお、繊維生地を着色するために用いられる材料としては、上述したものに限定されず、各繊維生地の素材に合わせて適切なものを選択すればよい。
The fiber fabric may or may not be pre-colored. When pre-coloring the fiber fabric, the fiber fabric is colored with a disperse dye, a cationic dye, an acidic dye, a direct dye, a reactive dye, a vat dye, a sulfur dye or the like, a fluorescent whitening agent, or a pigment. can do.
Further, various treatments performed at the time of normal fiber coloring may be performed, such as a fixing treatment using synthetic tannin or the like, which is carried out when dyeing nylon with an acid dye.
The method for coloring the fiber is not particularly limited, and examples thereof include methods such as dyeing, dyeing, and printing.
The material used for coloring the fiber fabric is not limited to the above-mentioned material, and an appropriate material may be selected according to the material of each fiber fabric.
繊維生地には、本発明の目的を妨げない範囲で、カレンダー加工、難燃加工、制電加工、抗菌防臭加工、制菌加工、紫外線遮蔽加工、耐光向上加工、プラズマ処理などが施されていてもよい。 The fiber fabric is subjected to calendar processing, flame retardant processing, antistatic processing, antibacterial deodorant processing, antibacterial processing, ultraviolet shielding processing, light resistance improving processing, plasma processing, etc., as long as the object of the present invention is not impaired. May be good.
＜親水性膜＞
親水性膜は繊維生地の第１の面に積層された樹脂膜であり、無孔質である。
繊維生地の第１の面に親水性膜が積層されていることにより、繊維生地に優れた防風性と透湿性を付与することができる。
なお、本発明において「無孔質」とは、異物やピンホールなどによる膜の厚み方向の孔開き、物理的変形による亀裂の発生などによる膜の面方向の孔開き、といった意図しない欠点、及び繊維生地を構成する繊維の凹凸等に起因する膜の不連続部分を除き、本質的に膜に孔開きが存在しないことを意味する。
<Hydrophilic film>
The hydrophilic film is a resin film laminated on the first surface of the fiber fabric and is non-porous.
By laminating the hydrophilic film on the first surface of the fiber fabric, it is possible to impart excellent wind resistance and moisture permeability to the fiber fabric.
In the present invention, "non-porous" means unintended defects such as pores in the thickness direction of the film due to foreign matter or pinholes, and holes in the surface direction of the film due to cracks caused by physical deformation. It means that there are essentially no pores in the membrane except for the discontinuous portion of the membrane caused by the unevenness of the fibers constituting the fiber fabric.
親水性膜の素材としては親水性を有するものであれば特に限定されないが、例えばポリビニルアルコール、ポリ（メタ）アクリル酸、ポリ（メタ）アクリル酸エステル、ポリ（メタ）アクリルアミドやその誘導体、ポリアルキレンオキサイド鎖を主鎖や側鎖に有するポリウレタン等の樹脂などが挙げられる。これらの中でも、実着時の親水性膜と身体等との擦れによる親水性膜の剥離や欠損に耐性があることや、伸縮性を有する素材を用いて防風性生地全体に伸縮性を付与しやすいことから、ポリウレタンが好ましい。 The material of the hydrophilic film is not particularly limited as long as it has hydrophilicity, but for example, polyvinyl alcohol, poly (meth) acrylic acid, poly (meth) acrylic acid ester, poly (meth) acrylamide and its derivatives, and polyalkylene. Examples thereof include resins such as polyurethane having an oxide chain in the main chain and side chains. Among these, it is resistant to peeling and chipping of the hydrophilic film due to rubbing between the hydrophilic film and the body at the time of actual attachment, and a stretchable material is used to impart elasticity to the entire windproof fabric. Polyurethane is preferable because it is easy.
親水性膜には、顔料等の着色剤、ポリアルキレングリコール等の透湿性向上剤、イソシアネート系架橋剤、触媒、酸化防止剤、紫外線吸収剤などの添加剤が含まれていてもよい。 The hydrophilic film may contain a coloring agent such as a pigment, a moisture permeability improving agent such as polyalkylene glycol, an isocyanate-based cross-linking agent, a catalyst, an antioxidant, and an additive such as an ultraviolet absorber.
親水性膜の単位面積当たりの質量（目付）は５〜４５ｇ／ｍ２が好ましく、１０〜３５ｇ／ｍ２がより好ましく、１０〜３０ｇ／ｍ２がさらに好ましい。親水性膜の目付が上記下限値以上であれば、防風性を充分に発現できる。親水性膜の目付が上記上限値以下であれば、透湿性を充分に発現しつつ、軽量で風合いがソフトな防風性生地を得られやすくなる。特に、繊維生地が織物である場合、充分な引裂強力や縫目強力が得られやすくなる利点も有する。 Mass per unit area of the hydrophilic membrane (basis weight) is preferably 5~45g / m 2, more preferably 10~35g / m 2, more preferably 10 to 30 g / m 2. When the basis weight of the hydrophilic film is at least the above lower limit value, windproofness can be sufficiently exhibited. When the basis weight of the hydrophilic film is not more than the above upper limit value, it becomes easy to obtain a windproof fabric which is lightweight and has a soft texture while sufficiently exhibiting moisture permeability. In particular, when the fiber fabric is a woven fabric, it also has an advantage that sufficient tear strength and stitch strength can be easily obtained.
＜防風性生地の物性＞
（通気度）
一般的に、軽量化や風合いのソフト化のためには、繊維生地に積層する樹脂膜の目付を小さくし、樹脂膜の膜厚みを薄くすればよいが、その場合、意図せずに通気度が高くなる傾向がある。
しかし、上述した実施形態の防風性生地によれば、無孔質の親水性膜が繊維生地の第１の面に積層されているため、繊維生地に積層する親水性膜の目付が小さく、また膜厚みが薄くても、防風性を顕著に向上させることができる。例えば、本発明の防風性生地であれば、ＪＩＳ Ｌ １０９６：２０１０ Ａ法（フラジール形法）に準じて測定した通気度が５ｃｍ３／ｃｍ２・ｓ以下になりやすい。通気度は、３ｃｍ３／ｃｍ２・ｓ以下がより好ましい。防風性の観点からは通気度が低い方が好ましいが、必要以上に通気度を下げると親水性膜の目付が大きくなり、軽量性が損なわれたり風合いが硬化したりするおそれがある。そのため、通気度は０．０５ｃｍ３／ｃｍ２・ｓ以上が好ましい。
<Physical characteristics of windproof fabric>
(Breathability)
Generally, in order to reduce the weight and soften the texture, it is sufficient to reduce the basis weight of the resin film laminated on the fiber fabric and reduce the film thickness of the resin film, but in that case, the air permeability is unintentionally reduced. Tends to be high.
However, according to the windproof fabric of the above-described embodiment, since the non-porous hydrophilic film is laminated on the first surface of the fiber fabric, the weight of the hydrophilic film laminated on the fiber fabric is small, and the weight of the hydrophilic film is small. Even if the film thickness is thin, the windproof property can be remarkably improved. For example, in the case of the windproof fabric of the present invention, the air permeability measured according to the JIS L 1096: 2010 A method (Frazil type method) tends to be 5 cm 3 / cm 2 · s or less. The air permeability is more preferably 3 cm 3 / cm 2 · s or less. From the viewpoint of windproofness, it is preferable that the air permeability is low, but if the air permeability is lowered more than necessary, the basis weight of the hydrophilic film becomes large, and the lightness may be impaired or the texture may be hardened. Therefore, the air permeability is preferably 0.05 cm 3 / cm 2 · s or more.
（透湿度）
上述した実施形態の防風性生地によれば、親水性膜が繊維生地の第１の面に積層されているため、親水性膜が無孔質であっても透湿性を顕著に向上させることができる。例えば、本発明の防風性生地であれば、ＪＩＳ Ｌ １０９９：２０１２ Ａ−１法（塩化カルシウム法）に準じて測定した透湿度が４０００ｇ／ｍ２・２４ｈｒｓ以上になりやすく、また、ＪＩＳ Ｌ １０９９：２０１２ Ｂ−１法（酢酸カリウム法）に準じて測定した透湿度が２００００ｇ／ｍ２・２４ｈｒｓ以上になりやすい。より好ましくはＡ−１法に準じて測定した透湿度が５０００ｇ／ｍ２・２４ｈｒｓ以上であり、Ｂ−１法に準じて測定した透湿度が３００００ｇ／ｍ２・２４ｈｒｓ以上である。一方、透湿度が高すぎると汗の蒸発が早すぎて体が冷えてしまうおそれがある。そのため、Ａ−１法に準じて測定した透湿度は２００００ｇ／ｍ２・２４ｈｒｓ以下が好ましく、Ｂ−１法に準じて測定した透湿度は１０００００ｇ／ｍ２・２４ｈｒｓ以下が好ましい。
(Humidity permeability)
According to the windproof fabric of the above-described embodiment, since the hydrophilic film is laminated on the first surface of the fiber fabric, the moisture permeability can be significantly improved even if the hydrophilic film is non-porous. can. For example, if the windproof fabric of the present invention, JIS L 1099: 2012 A- 1 method moisture permeability was measured according to (calcium chloride method) tends to be more 4000g / m 2 · 24hrs, also, JIS L 1099 : 2012 B-1 method moisture permeability was measured in accordance with (potassium acetate method) tends to be more 20000g / m 2 · 24hrs. More preferably analogously moisture permeability was measured in the 5000g / m 2 · 24hrs or more A-1 method, the moisture permeability was measured in accordance with B-1 method is 30000g / m 2 · 24hrs or more. On the other hand, if the moisture permeability is too high, the sweat evaporates too quickly and the body may get cold. Therefore, the moisture permeability was measured in accordance with Method A-1 is preferably from 20000g / m 2 · 24hrs, water vapor permeability was measured in accordance with B-1 method is preferably not more than 100000g / m 2 · 24hrs.
（撥水度）
上述した実施形態の防風性生地によれば、繊維生地の繊維表面に特定の撥水剤及び第４族元素化合物が付着しているため、撥水性を顕著に向上させることができる。特に、繊維生地の第２の面が露出していれば、撥水性をより顕著に向上させることができる。例えば、本発明の防風性生地であれば、露出した繊維生地の第２の面のＪＩＳ Ｌ １０９２：２００９に記載のはっ水度試験（スプレー試験）に準じて測定した撥水度が４級以上になりやすい。撥水度は５級がより好ましい。
(Water repellency)
According to the windproof fabric of the above-described embodiment, since the specific water repellent and the Group 4 element compound are attached to the fiber surface of the fiber fabric, the water repellency can be remarkably improved. In particular, if the second surface of the fiber fabric is exposed, the water repellency can be improved more remarkably. For example, in the case of the windproof fabric of the present invention, the water repellency measured according to the water repellency test (spray test) described in JIS L 1092: 2009 on the second surface of the exposed fiber fabric is grade 4. It tends to be more than that. The water repellency is more preferably 5th grade.
（破断伸度）
上述した実施形態の防風性生地によれば、伸縮性を顕著に向上させることができる。例えば、本発明の防風性生地であれば、経方向及び緯方向の少なくとも一方のＪＩＳ Ｌ １０９６：２０１０ ＪＩＳ法 Ａ法（ストリップ法）に準じて測定した破断伸度が３０％以上になりやすい。より好ましくは経方向及び緯方向の破断伸度が３０％以上であり、さらに好ましくは経方向及び緯方向の破断伸度が５０％以上である。
(Elongation at break)
According to the windproof fabric of the above-described embodiment, the elasticity can be remarkably improved. For example, in the case of the windproof fabric of the present invention, the breaking elongation measured according to JIS L 1096: 2010 JIS method A (strip method) in at least one of the warp direction and the weft direction tends to be 30% or more. More preferably, the elongation at break in the warp and weft directions is 30% or more, and more preferably, the elongation at break in the warp and weft directions is 50% or more.
＜防風性生地の製造方法＞
次に、本発明の防風性生地の製造方法の一例について説明する。なお、本発明は以下に説明する製造方法で得られるものに限定されるものではない。
<Manufacturing method of windproof fabric>
Next, an example of the method for producing the windproof fabric of the present invention will be described. The present invention is not limited to that obtained by the production method described below.
まず、基材となる繊維生地を準備する。繊維生地としては上述したものが用いられ、必要に応じて、湯洗い、精練、リラックス、熱セット等の加工を施す。前記加工は公知の方法で行えばよい。また、本発明の効果を損なわない範囲内において、他の性能を付与するため、特殊な条件にて前記加工を施してもよい。
さらに、必要に応じ繊維生地に対して、染色加工、捺染加工、カレンダー加工、難燃加工、制電加工、抗菌防臭加工、制菌加工、紫外線遮蔽加工、耐光向上加工、プラズマ処理などの加工を施してもよい。
First, a fiber dough as a base material is prepared. As the fiber dough, the above-mentioned one is used, and if necessary, processing such as washing with hot water, scouring, relaxing, and heat setting is performed. The processing may be performed by a known method. Further, in order to impart other performance within a range that does not impair the effect of the present invention, the above-mentioned processing may be performed under special conditions.
Furthermore, if necessary, textile fabrics can be dyed, printed, calendared, flame-retardant, antistatic, antibacterial and deodorant, antibacterial, UV-shielded, light-resistant, plasma-treated, etc. May be given.
次いで、繊維生地に対して、第４族元素化合物による処理、及び撥水加工を施す。
第４族元素化合物による処理では、第４族元素化合物を溶媒に溶解又は分散媒に分散させた処理液（１）を、パディング法やスプレー法等で繊維生地に付与した後、４０〜１８０℃にて１０〜６００秒程度乾燥し、必要に応じて１３０〜２００℃にて５〜３００秒程度の熱処理を行う。
一方、撥水加工では、炭素数７以上のパーフルオロアルキル基を有しない撥水剤を溶媒又は分散媒に溶解又は分散させた処理液（２）を、パディング法やスプレー法等で繊維生地に付与した後、４０〜１４０℃にて１０〜６００秒程度乾燥し、必要に応じて１３０〜２００℃にて５〜３００秒程度の熱処理を行う。
なお、第４族元素化合物による処理、及び撥水加工は、同時に行ってもよいし、別々に行ってもよい。別々に行う場合には、撥水剤により繊維生地への処理液（１）の浸透が阻害されないようにするため、第４族元素化合物による処理を撥水加工よりも前に行うことが好ましい。
Next, the fiber fabric is treated with a Group 4 element compound and water-repellent.
In the treatment with the Group 4 element compound, the treatment liquid (1) in which the Group 4 element compound is dissolved in a solvent or dispersed in a dispersion medium is applied to the fiber dough by a padding method, a spray method, or the like, and then 40 to 180 ° C. Dry for about 10 to 600 seconds, and if necessary, heat-treat at 130 to 200 ° C. for about 5 to 300 seconds.
On the other hand, in the water-repellent treatment, a treatment liquid (2) in which a water-repellent agent having 7 or more carbon atoms and having no perfluoroalkyl group is dissolved or dispersed in a solvent or a dispersion medium is applied to a fiber fabric by a padding method, a spray method, or the like. After the application, it is dried at 40 to 140 ° C. for about 10 to 600 seconds, and if necessary, heat-treated at 130 to 200 ° C. for about 5 to 300 seconds.
The treatment with the Group 4 element compound and the water-repellent treatment may be performed at the same time or separately. When they are performed separately, it is preferable to perform the treatment with the Group 4 element compound before the water-repellent treatment so that the permeation of the treatment liquid (1) into the fiber fabric is not hindered by the water-repellent agent.
処理液（１）中の第４族元素化合物の濃度は、繊維生地によるピックアップ量に応じ、防風性生地１ｍ２あたり０．１ｇ以上含まれるよう調節することが好ましい。
処理液（１）に用いられる溶媒又は分散媒としては、例えば水；イソプロピルアルコール、ｎ−ブチルアルコール等のアルコール系溶媒；メチルエチルケトン、メチルイソブチルケトン等のケトン系溶媒；酢酸エチル、酢酸ブチル等のエステル系溶媒；エチルセロソルブ、プロピルセロソルブ等のセロソルブ系溶媒；Ｎ，Ｎ−ジメチルホルムアミド、テトラヒドロフラン等のその他の非プロトン性極性溶媒などが挙げられる。
The concentration of the Group 4 element compound in the treatment liquid (1) is preferably adjusted so as to be contained in an amount of 0.1 g or more per 1 m 2 of the windproof dough, depending on the amount of pick-up by the fiber dough.
Examples of the solvent or dispersion medium used in the treatment liquid (1) include water; alcohol solvents such as isopropyl alcohol and n-butyl alcohol; ketone solvents such as methyl ethyl ketone and methyl isobutyl ketone; esters such as ethyl acetate and butyl acetate. System solvents; cellosolve-based solvents such as ethyl cellosolve and propyl cellosolve; other aprotonic polar solvents such as N, N-dimethylformamide and tetrahydrofuran can be mentioned.
処理液（２）中の撥水剤の濃度は、使用する撥水剤の種類、目的とする撥水性、得られる防風性生地の風合いなどに応じて適宜設定すればよい。例えば、処理液（２）の総質量に対して、撥水剤の含有量は固形分換算で０．１〜１０質量％であることが好ましい。
処理液（２）に用いられる溶媒又は分散媒としては、例えば水；イソプロピルアルコール、ｎ−ブチルアルコール等のアルコール系溶媒；メチルエチルケトン、メチルイソブチルケトン等のケトン系溶媒；酢酸エチル、酢酸ブチル等のエステル系溶媒；エチルセロソルブ、プロピルセロソルブ等のセロソルブ系溶媒；Ｎ，Ｎ−ジメチルホルムアミド、テトラヒドロフラン等のその他の非プロトン性極性溶媒；トルエン、キシレン等の芳香族炭化水素系溶媒；石油エーテル、ミネラルターペン等の脂肪族炭化水素系溶媒などが挙げられる。
The concentration of the water repellent in the treatment liquid (2) may be appropriately set according to the type of the water repellent used, the target water repellency, the texture of the obtained windproof fabric, and the like. For example, the content of the water repellent is preferably 0.1 to 10% by mass in terms of solid content with respect to the total mass of the treatment liquid (2).
Examples of the solvent or dispersion medium used in the treatment liquid (2) include water; alcohol solvents such as isopropyl alcohol and n-butyl alcohol; ketone solvents such as methyl ethyl ketone and methyl isobutyl ketone; esters such as ethyl acetate and butyl acetate. System solvent; Cellosolve solvent such as ethyl cellosolve and propyl cellosolve; Other aprotonic polar solvents such as N, N-dimethylformamide and tetrahydrofuran; Aromatic hydrocarbon solvents such as toluene and xylene; Petroleum ether, mineral tarpen and the like. Examples thereof include an aliphatic hydrocarbon solvent.
なお、処理液（１）及び処理液（２）には、それぞれ必要に応じて、撥水性を向上させるための疎水性シリカや、洗濯などに対する耐久性を向上させるためのイソシアネート架橋剤、繊維への浸透剤などの添加剤が含まれていてもよい。 The treatment liquid (1) and the treatment liquid (2) are, if necessary, hydrophobic silica for improving water repellency, an isocyanate cross-linking agent for improving durability against washing, and fibers. Additives such as penetrants may be included.
次いで、第４族元素化合物による処理、及び撥水加工を施した後の繊維生地の第１の面に、無孔質の親水性膜を積層する（積層加工）。親水性膜を積層する手段としては、例えばコーティング法、ラミネート法などが挙げられる。
コーティング法では、粘度を調節した親水性膜の素材（樹脂）をナイフコーター、ブレードコーター、グラビアコーター、リバースコーター、押し出しコーターなどを用いて、繊維生地の第１の面に直接コーティングする。親水性膜の素材の粘度を調節する方法としては、素材に溶媒又は分散媒を添加したり、素材を熱溶融したりする方法が挙げられる。
ラミネート法では、離型紙上などに親水性膜の素材（樹脂）をキャストし、必要に応じて接着剤を介して繊維生地の第１の面にラミネートする。
加熱による溶媒や分散媒の除去、活性エネルギー線の照射による重合反応の促進、冷却による樹脂の固化などの製膜処理は、用いた手法に合わせて適宜行えばよい。
Next, a non-porous hydrophilic film is laminated on the first surface of the fiber fabric after the treatment with the Group 4 element compound and the water-repellent treatment (lamination processing). Examples of the means for laminating the hydrophilic film include a coating method and a laminating method.
In the coating method, the material (resin) of the hydrophilic film whose viscosity is adjusted is directly coated on the first surface of the fiber fabric by using a knife coater, a blade coater, a gravure coater, a reverse coater, an extrusion coater or the like. Examples of the method for adjusting the viscosity of the material of the hydrophilic membrane include a method of adding a solvent or a dispersion medium to the material and a method of heat-melting the material.
In the laminating method, a hydrophilic film material (resin) is cast on a release paper or the like, and if necessary, laminated on the first surface of the fiber fabric via an adhesive.
Film-forming treatments such as removal of the solvent and dispersion medium by heating, promotion of the polymerization reaction by irradiation with active energy rays, and solidification of the resin by cooling may be appropriately performed according to the method used.
なお、積層加工は、第４族元素化合物による処理、及び撥水加工の前に行ってもよいし、後に行ってもよいが、コーティング法により親水性膜を繊維生地の第１の面に積層する場合には、繊維生地へ樹脂が含浸しにくくなるとの観点から、第４族元素化合物による処理、及び撥水加工の後に行うことが好ましい。 The laminating process may be performed before the treatment with the Group 4 element compound and the water-repellent processing, or may be performed after the laminating process, but the hydrophilic film is laminated on the first surface of the fiber fabric by the coating method. In this case, it is preferable to carry out the treatment after the treatment with the Group 4 element compound and the water repellent treatment from the viewpoint that the resin is less likely to be impregnated into the fiber fabric.
このようにして、炭素数７以上のパーフルオロアルキル基を有しない撥水剤及び第４族元素化合物が表面に付着した繊維で構成された繊維生地の第１の面に無孔質の親水性膜が積層され、繊維生地の第２の面が露出した防風性生地が得られる。 In this way, the first surface of the fiber dough composed of fibers having a water repellent having no perfluoroalkyl group having 7 or more carbon atoms and a group 4 element compound adhered to the surface is hydrophilic and non-porous. A windproof fabric is obtained in which the films are laminated and the second surface of the fiber fabric is exposed.
＜作用効果＞
以上説明した本発明の防風性生地は、繊維生地の第１の面に無孔質の親水性膜が積層しているので、優れた防風性及び透湿性を有する。また、繊維生地の繊維表面には、炭素数７以上のパーフルオロアルキル基を有しない撥水剤及び第４族元素化合物が付着しているので、低環境負荷であり、かつ親水性膜を有していながも、優れた撥水性を発現できる。
また、本発明の防風性生地は、炭素数７以上のパーフルオロアルキル基を有しない撥水剤と第４族元素化合物とを併用することで撥水性の低下を抑制しているので、平凡で安価な繊維生地はもちろんのこと、伸縮性を有し頻繁に目開きが発生する繊維生地や、軽量化や風合いのソフト化のために細い糸や密度の低い繊維生地などを使用することができる。
<Action effect>
The windproof fabric of the present invention described above has excellent windproofness and moisture permeability because a non-porous hydrophilic film is laminated on the first surface of the fiber fabric. Further, since a water repellent agent having no perfluoroalkyl group having 7 or more carbon atoms and a group 4 element compound are attached to the fiber surface of the fiber fabric, it has a low environmental load and has a hydrophilic film. However, it can develop excellent water repellency.
Further, the windproof fabric of the present invention is mediocre because the decrease in water repellency is suppressed by using a water repellent agent having no perfluoroalkyl group having 7 or more carbon atoms and a group 4 element compound in combination. In addition to inexpensive fiber fabrics, fiber fabrics that are elastic and frequently open, and fine threads and low-density fiber fabrics can be used to reduce weight and soften the texture. ..

衣類としては特に制限されないが、例えばジャケット、シャツ、ワンピース、セーター、カーディガン等の一般衣料、ユニフォーム、ウィンドブレーカー、タイツ、ウォームアップスーツ等のスポーツ用衣料、作業服などが挙げられる。

Further, the windproof fabric obtained in each example had a breaking elongation of at least one of the warp direction and the weft direction of 30% or more, and was excellent in elasticity.
On the other hand, as is clear from Table 2, the windproof fabrics of Comparative Examples 1 to 3 that were not treated with the Group 4 element compound had a resin film because the Group 4 element compound did not adhere to the fiber surface. The water repellency was good before laminating, but the water repellency decreased when the resin film was laminated.
The windproof fabric of Comparative Example 4 which was not subjected to the water repellent treatment was inferior in water repellency.
The windproof fabric of Comparative Example 5 in which a non-porous hydrophobic film was laminated on the first surface of the fiber fabric was inferior in moisture permeability.
The windbreaker fabric of Comparative Example 6 in which the windbreaker fabric of Comparative Example 5 was needle punched had a porous hydrophobic film, and therefore conformed to the JIS L 1099: 2012 A-1 method (calcium chloride method). Moisture permeability was improved, but windbreak was reduced.
