Abstract
Description
本発明は、衣料用途、資材用途に利用される繊維布帛であり、吸水した水分が逆戻りしにくく、或いは、発汗によりべとつきを感じさせない布帛に関するものである。 The present invention relates to a textile fabric used for apparel use and material use, and relates to a fabric that hardly absorbs absorbed water or does not feel sticky due to perspiration.
汗で濡れた布帛が肌にべたつかないようにする技術としては、例えば、特許文献１には、布帛の片面全体に撥水処理を施し、他面には全く撥水性を有しないかまたは撥水度を弱めた撥水処理を施すことが開示されている。しかしこの方法では汗が残留した場合、肌と接する布帛面全体を撥水処理した構成ではかえって汗を吸収しなくなり、べたつき感は解消されにくい。
また、特許文献２や特許文献３には、片面が合成繊維からなる疎水性繊維素材、他面が天然繊維からなる吸湿性繊維素材からなる二重構造の布帛が開示されている。しかしながら、これらの素材は、２種類以上の素材の組み合わせからなるものであるため、染色性に問題があったり、製造コストが高くなるおそれがあった。
また、特許文献４には、吸水性を有する布帛の片面に、撥水剤を模様状に疎水加工した布帛が開示されている。しかし、この布帛は素材の凹凸に関係なく疎水性部分、親水性部分が柄模様にて決められてしまうため、表面に出ている凸部分を効率的に疎水化出来ない。このため、表面のべた付きの防止効果が悪くなってしまうおそれがある。更に、撥水性薬剤のみを付与しているため、耐久性が悪いという問題があった。
As a technique for preventing the fabric wet with sweat from sticking to the skin, for example, in Patent Document 1, water repellency treatment is applied to one entire surface of the fabric, and the other surface has no water repellency or water repellency. It is disclosed to perform a water repellent treatment with a reduced degree. However, in this method, when sweat remains, the configuration in which the entire fabric surface in contact with the skin is subjected to water-repellent treatment does not absorb the sweat and the sticky feeling is difficult to be eliminated.
Patent Documents 2 and 3 disclose a double-structured fabric made of a hydrophobic fiber material made of synthetic fiber on one side and a hygroscopic fiber material made of natural fiber on the other side. However, since these materials are composed of a combination of two or more types of materials, there is a possibility that there is a problem in dyeability and a manufacturing cost is increased.
Patent Document 4 discloses a fabric in which a water repellent is hydrophobically processed into a pattern on one side of a fabric having water absorption. However, in this fabric, the hydrophobic part and the hydrophilic part are determined by the pattern regardless of the unevenness of the material, so that the convex part appearing on the surface cannot be efficiently hydrophobized. For this reason, there exists a possibility that the prevention effect of surface stickiness may worsen. Furthermore, since only the water repellent chemical is applied, there is a problem that durability is poor.
本発明者らは上記課題を解決すべく鋭意研究を重ねた結果、繊維構造物に撥水剤を布帛の凸部に部分的に配する事により、該繊維構造物が汗を吸収した時もベトツキ感を軽減できる事を見出し、この知見に基づいて本発明を完成させたものである。 As a result of intensive research to solve the above problems, the present inventors have partially arranged a water repellent agent on the convex portion of the fabric to absorb the sweat. It has been found that the stickiness can be reduced, and the present invention has been completed based on this finding.
すなわち、本発明は、（１）に、ＪＩＳ Ｌ−１９０７（滴下法）による吸水時間が３０秒以下である吸水性を有する布帛の片面の凸部分にのみ撥水層を形成してなる撥水性繊維布帛であって、撥水層部分が布帛の片側の面積の５〜２５％で、撥水剤が布帛重量の０．０５〜１５％付与された繊維布帛であり、撥水剤を付与された面のＪＩＳ Ｌ−１９０７（滴下法）による吸水時間が３０秒以下である繊維布帛である。
また（２）に、撥水層が架橋されてなる（１）記載の撥水性繊維布帛である。
また、（３）に、撥水剤に熱発泡性薬剤が含まれていることを特徴とする（１）乃至（２）記載の繊維布帛である。
また、（４）に、発泡性薬剤に高分子樹脂が混合されていることを特徴とする（３）記載の繊維布帛。
また、（５）に、繊維布帛全体を水で濡らした後、該繊維素材の撥水剤を付与してある側からの吸水性シートによる吸水量が、撥水剤を付与してない側からの吸水性シートによる吸水量の７０％以下であることを特徴とする（１）乃至（４）記載の繊維素材である。
That is, in the present invention, the water-repellent layer is formed by forming a water-repellent layer only on the convex portion on one side of the fabric having water-absorbing time of 30 seconds or less according to JIS L-1907 (drop method). A fiber fabric having a water-repellent layer portion of 5 to 25% of the area on one side of the fabric and a water-repellent agent of 0.05 to 15% of the weight of the fabric. This is a fiber fabric having a water absorption time of 30 seconds or less according to JIS L-1907 (drop method) on the back surface.
The water repellent fiber fabric according to (1), wherein the water repellent layer is crosslinked with (2).
(3) The fiber fabric according to (1) or (2), wherein the water repellent contains a thermal foaming agent.
(4) The fiber fabric according to (3), wherein a polymer resin is mixed with the foaming agent.
Further, in (5), after the entire fiber fabric is wetted with water, the amount of water absorbed by the water absorbent sheet from the side where the water repellent of the fiber material is applied is from the side where the water repellent is not applied. The fiber material according to any one of (1) to (4), which is 70% or less of the amount of water absorbed by the water absorbent sheet.
本発明の布帛は、直接肌に触れる凸部分に撥水処理がなされているので、汗を吸って濡れた布帛が肌にまつわりつくなどのベトツキ感が無く、また撥水処理された凸部以外は吸水処理されているので汗が素早く吸収され肌を伝って流れることがないため着心地は快適になる。そのため、ジョギングウエアーやバスケットやテニスのウエアーなどスポーツ用アンダーウエアーに最適であり、更に、衣類だけでなく吸水性がよく、吸水した水分を逆戻りさせないシーツやバスマットなどの用途にも好適に用いられる。 Since the fabric of the present invention has a water-repellent treatment on the convex portion that directly touches the skin, there is no stickiness such as the fabric that has been sucked in and sweated around the skin. Since it is water-absorbed, sweat is absorbed quickly and does not flow through the skin, making it comfortable to wear. Therefore, it is most suitable for underwear for sports such as jogging wear, baskets, and tennis wear, and it is suitable not only for clothing but also for uses such as sheets and bath mats that have good water absorption and do not reverse the absorbed water.
以下、本発明を詳細に説明する。本発明の繊維布帛は、ＪＩＳ Ｌ−１９０７（滴下法）による吸水時間が３０秒以下である吸水性を有する布帛の片面の凸部分にのみ撥水層を形成してなる撥水性繊維布帛であって、撥水層部分が布帛の片側の面積の５〜２５％で、且つ、布帛重量の０．０５〜１５％で付与してなる繊維布帛であり、撥水剤を付与された面のＪＩＳ Ｌ−１９０７（滴下法）による吸水時間が３０秒以下である繊維布帛である。
本発明において繊維布帛の素材は、ポリエステル、ナイロン、アクリル、ポリビニルアルコールなどの合成繊維、レーヨンなどの再生繊維、綿、麻、羊毛、絹などの天然繊維やこれらの混繊、交編織品であって、特に限定されるものではないが、吸水性のない素材については吸水加工を施してあるものを用いることが必要である。
また、吸水性を有する布帛はＪＩＳ Ｌ−１９０７の滴下法による吸水時間が３０秒以下であることが必要である。吸水時間が３０秒より長い繊維素材では、繊維素材自体の吸水性が悪いため、ベトツキ感を感じたりしやすくなる為好ましくない。
用いられる吸水剤は公知のものを用いることができ、ポリエステル系樹脂、ウレタン系樹脂、アクリル系樹脂やポリエチレングリコールやその誘導体などを挙げることができるが特に限定されるものではない。吸水剤の付与方法は吸尽法やパディング法などを用いることができるが、繊維布帛がポリエステル系繊維からなるときは、ポリエステル系吸水剤を用いて染色と同時に行う吸尽法を用いることが吸水性能やコストの面から好ましい。
また、用いる布帛の形態としては織物、編物、不織布などのいかなるものであっても良い。
又、これらの繊維素材に、防炎加工、抗菌加工などの化学処理や、起毛加工、カレンダー加工等の物理処理を施すことも可能である。
Hereinafter, the present invention will be described in detail. The fiber fabric of the present invention is a water-repellent fiber fabric in which a water-repellent layer is formed only on the convex portion on one side of a fabric having water absorbency with water absorption time of 30 seconds or less according to JIS L-1907 (dropping method). The water repellent layer portion is a fiber fabric formed by applying 5 to 25% of the area of one side of the fabric and 0.05 to 15% of the weight of the fabric, and the surface provided with a water repellent is JIS. A fiber fabric having a water absorption time of 30 seconds or less according to L-1907 (drop method).
In the present invention, the material of the fiber fabric is a synthetic fiber such as polyester, nylon, acrylic or polyvinyl alcohol, a regenerated fiber such as rayon, a natural fiber such as cotton, hemp, wool or silk, or a mixed fiber or a knitted woven product thereof. Although not particularly limited, it is necessary to use a material that has been subjected to water absorption processing for a material that does not absorb water.
In addition, the water-absorbing fabric needs to have a water absorption time of 30 seconds or less according to the dropping method of JIS L-1907. A fiber material having a water absorption time longer than 30 seconds is not preferable because the fiber material itself has poor water absorption, and it tends to feel sticky.
Known water-absorbing agents can be used, and examples thereof include polyester resins, urethane resins, acrylic resins, polyethylene glycol and derivatives thereof, but are not particularly limited. As a method for applying the water absorbing agent, an exhaust method, a padding method, or the like can be used. However, when the fiber fabric is made of polyester fiber, it is preferable to use an exhaust method that is performed simultaneously with dyeing using a polyester water absorbent. It is preferable in terms of performance and cost.
Moreover, as a form of the fabric to be used, any form such as a woven fabric, a knitted fabric, and a non-woven fabric may be used.
These fiber materials can be subjected to chemical treatment such as flameproofing and antibacterial treatment, and physical treatment such as raising and calendering.
また、本発明において用いることが出来る撥水性薬剤は、フッ素系薬剤、シリコン系薬剤、パラフィン系薬剤、等の通常用いられている撥水剤、及びそれらの混合物挙げることができ、これらの薬剤を適当な濃度に希釈して用いることが出来る。
また、撥水剤は布帛の片側の凸部に付与され、その付与面積は布帛の面積の５〜２５％である。付与面積が５％未満であると吸水性はあるが、塗布面の撥水性が不十分となり、表側と裏側の保水性に差が少なくなりべたつきを感じやすくなるおそれがある。また２５％より大きくなると吸水性が悪くなる。
また、付与する撥水剤の量は布帛の重量比で０．０５〜１５％である。重量比０．０５％未満の場合、吸水性はあるが、塗布面の撥水性が不十分となり、べたつきを感じるおそれがある。１５％より多くなると、吸水性が悪くなり、且つ、塗布した部分の反対側（裏側）にも撥水剤が浸みだしてしまい、表側と裏側の保水性に差が少なくなるおそれがある。
これらの撥水剤の中に、耐久性を向上させるための架橋剤、触媒、目的の風合いにするための柔軟剤、硬め剤、又、表面凸部分の撥水性を助長するための熱発泡性薬剤、加工剤の浸透を調整するための浸透剤、増粘剤などを目的に応じて添加することも出来る。用いられる架橋剤の例としては、トリメチロールメラミン、ヘキサメチロールメラミン等のメラミン系樹脂、トルエンジイソシアネート、ジフェニルメチレンンジイソシアネート、ヘキサメチレンジイソシアネート等、及びそれらを重亜硫酸ソーダなどのブロック化剤にてブロックし水分散体としたイソシアネート系樹脂やポリオキシエチレンジグリジルエーテル等のエポキシ系樹脂を挙げることができる。
Examples of the water-repellent agent that can be used in the present invention include a commonly used water-repellent agent such as a fluorine-based drug, a silicon-based drug, and a paraffin-based drug, and a mixture thereof. It can be used after diluting to an appropriate concentration.
Moreover, a water repellent is provided to the convex part of the one side of a fabric, The provision area is 5 to 25% of the area of a fabric. If the applied area is less than 5%, there is water absorption, but the water repellency of the coated surface becomes insufficient, and there is a possibility that the difference in water retention between the front side and the back side becomes small and it becomes easy to feel stickiness. On the other hand, if it exceeds 25%, the water absorption is worsened.
The amount of the water repellent applied is 0.05 to 15% in terms of the weight ratio of the fabric. When the weight ratio is less than 0.05%, there is water absorption, but the water repellency of the coated surface becomes insufficient, and stickiness may be felt. If it exceeds 15%, the water absorption is worsened, and the water repellent agent also oozes out on the opposite side (back side) of the applied part, which may reduce the difference in water retention between the front side and the back side.
Among these water repellents, cross-linking agents for improving durability, catalysts, softeners for enhancing the desired texture, hardeners, and thermal foaming properties to promote water repellency of surface convex portions A penetrant, a thickener and the like for adjusting the penetration of the drug and the processing agent can be added depending on the purpose. Examples of crosslinking agents used include melamine resins such as trimethylol melamine and hexamethylol melamine, toluene diisocyanate, diphenylmethylene diisocyanate, hexamethylene diisocyanate, and the like, and these are blocked with a blocking agent such as sodium bisulfite. Mention may be made of epoxy resins such as isocyanate resins and polyoxyethylene diglycidyl ether in water dispersion.
また撥水剤の布帛への付与方法は、スクリーン捺染法、ローラ捺染法、キスコータ法、グラビアコーティング法、スプレー法などなどを挙げることがでるが、特に限定されない。 Examples of the method for applying the water repellent to the fabric include a screen printing method, a roller printing method, a kiss coater method, a gravure coating method, and a spray method, but are not particularly limited.
このように吸水性を有する布帛の片面の凸部に撥水剤を付与されてなる布帛の撥水剤を付与された面のＪＩＳ Ｌ−１９０７（滴下法）による吸水時間は３０秒以下であることが必要である。３０秒より長いと汗などの水分を吸収して、その吸水面から水分を戻らなくすることや、吸水面の保水性を低くして乾いた状態にすることによるべたつき感の防止などの効果が悪くなる。 The water absorption time according to JIS L-1907 (dropping method) of the surface of the fabric having the water repellent applied to the convex portion on one side of the fabric having water absorption is 30 seconds or less. It is necessary. If it is longer than 30 seconds, it absorbs moisture such as sweat and prevents moisture from returning from the water-absorbing surface, and the water-absorbing surface has low water retention to prevent it from becoming sticky. Deteriorate.
また、撥水剤に発泡性薬剤を添加して付与することが好ましい。特に熱発泡性薬剤添加は、加工剤付与後に、熱処理を行うことにより、表面凸部分に撥水性発泡層を作ることが出来、表面凸部分がよりドライタッチになった撥水部分が形成される。更に発泡部分が形成されることにより吸水性は損なわれずに吸収した水分が戻るのを防ぐ効果が向上する。
用いる発泡性薬剤としては、加熱により気化膨張する液体ブタンや低分子量パラフィンなどの低沸点化合物をマイクロカプセル化したものや、炭酸水素ナトリウムや４，４‘−オキシビス（ベンゼンスルホニルヒドラジド）などの化学分解型発泡性薬剤を挙げることができ、これら単独或いはこれらを混合して用いることができる。
また、発泡性薬剤の発泡倍率は５〜９０％が好ましい。発泡倍率が５％未満であると効果が乏しく凸部に撥水剤を付与する効果が十分でなくなるおそれがあり、９０％より大きいと撥水剤の耐摩耗性が悪くなり、耐久性に問題のでるおそれがある。
また、発泡性薬剤に高分子樹脂を混合させることにより安定した発泡層が形成される。高分子樹脂としてはポリアクリル酸エステルやポリウレタンなどを挙げることができるが特に限定されるものではない。
Moreover, it is preferable to add and add a foaming chemical | medical agent to a water repellent. In particular, when a heat-foaming agent is added, a water-repellent foam layer can be formed on the surface convex portion by applying a heat treatment after applying the processing agent, and a water-repellent portion where the surface convex portion is more dry touched is formed. . Further, the formation of the foamed portion improves the effect of preventing the absorbed moisture from returning without impairing the water absorption.
Effervescent agents used include microcapsules of low-boiling compounds such as liquid butane that vaporizes and expands when heated, low molecular weight paraffin, and chemical decomposition such as sodium bicarbonate and 4,4'-oxybis (benzenesulfonylhydrazide). Examples thereof include mold-type foaming agents, and these can be used alone or in combination.
The foaming ratio of the foaming agent is preferably 5 to 90%. If the expansion ratio is less than 5%, the effect is poor and the effect of imparting a water repellent to the convex portion may not be sufficient. If it exceeds 90%, the abrasion resistance of the water repellent deteriorates and there is a problem in durability. There is a risk of getting on.
In addition, a stable foam layer is formed by mixing a polymer resin with the foaming agent. Examples of the polymer resin include polyacrylic acid ester and polyurethane, but are not particularly limited.
このように作成した繊維布帛は、繊維布帛全体を水で濡らした後、該繊維素材の表裏両側からの吸水性シートによる吸水量が、撥水剤を付与してある側の吸水量が、撥水剤を付与してない側からの吸水量の７０％以下であることが好ましい。７０％より大きいと、本発明の目的である、「水や汗を吸って、吸った面から戻らない」「水や汗を吸っても、吸った面の保水性を低くして、乾いた状態にする」の十分な効果が得られないおそれがある。 In the fiber fabric prepared in this way, after the entire fiber fabric is wetted with water, the water absorption amount by the water absorbent sheet from both the front and back sides of the fiber material is such that the water absorption amount on the side to which the water repellent agent has been applied. It is preferable that it is 70% or less of the amount of water absorption from the side which has not provided the liquid medicine. When it is larger than 70%, the object of the present invention is “suck water or sweat and does not return from the sucked surface” “Even if water or sweat is sucked, the water retention of the sucked surface is lowered and dried. There is a possibility that the sufficient effect of “state” cannot be obtained.
この繊維素材の用途としては、衣料用途として、撥水性薬剤を付与してある側を肌側としてシャツなどに用いた場合、人が着用し汗をかいたとき、撥水性薬剤がついていない部分から汗を吸い上げ、外側に拡散し、且つ、撥水性の薬剤が付与されている側の肌面側繊維素材表面は、汗が吸い込みにくいため、着用者は、汗のべた付き感が軽減され、快適性が得られる。
また、衣料以外の用途として、撥水性薬剤を付与してある側を上側として、雨天時に用いる玄関マット材として用いた場合、雨に濡れた靴底が、玄関マット材に接した場合、撥水性薬剤がついていない部分から雨水を吸い込み、下側に拡散し、且つ、撥水性の薬剤が付与されている側には、雨水がもどりにくいため、玄関内に靴底の雨水が入りにくくなる素材に使用できる。
更に、撥水性薬剤を付与してある面を手で持つ側として、濡れた部分を拭き取る素材として用いた場合、手に濡れた物がしみ込んで来ることを防ぐことが出来る。
As the use of this fiber material, as a clothing application, when used on a shirt etc. with the side to which the water-repellent agent is applied as the skin side, when a person wears and sweats, from the part without the water-repellent agent Because the surface of the fiber on the skin side that absorbs sweat, diffuses outward, and has a water-repellent agent applied to it, it is difficult for the wearer to inhale sweat. Sex is obtained.
In addition, as a use other than clothing, when the water-repellent agent-supplied side is used as the upper side, and used as a door mat material used in rainy weather, when a rainy shoe sole touches the door mat material, Rainwater is sucked in from the part where no medicine is attached, diffuses downward, and it is difficult for rainwater to return to the side where water-repellent medicine is applied. Can be used.
Further, when the wetted part is used as a material for wiping the wet part as the side having the water-repellent agent applied to the hand, it is possible to prevent the wet object from getting into the hand.
