Description
本発明は、伸縮性布帛に関し、特に、同一布帛上に少なくとも２種の異なる伸縮弾性領域を有し、必要に応じて色柄表現が施された伸縮性布帛に関する。 The present invention relates to a stretchable fabric, and more particularly, to a stretchable fabric having at least two different stretchable elastic regions on the same fabric and having a color pattern expressed as necessary.
近年、様々な手法を用いた運動機能性向上、疲労回復機能、疲労軽減機能、体型補整、または体型矯正などの機能を狙った高機能性布帛が開発されており、様々な分野で製品への展開が拡大してきている。その１つとしてポリウレタン繊維などの弾性繊維を使用した高い伸縮性をもった布帛があり、これらはスポーツやインナー分野で用いられている。これらの製品は着用時の不快感を軽減させ、目的に応じ必要な部位に必要な応力を与えた製品である。
必要な部位毎に応力を出す手法として、使用する糸の繊度や種類を変えたり組織を変更するなどの織編条件を変化させる手法、所定部分へ樹脂を付与する方法、所定部分を抜蝕加工する方法および布帛やテープ状物を所定場所に積層する方法などがある。
織編条件を変化させる方法は、応力差は得られやすく、応力もコントロールし易いが、糸の繊度や糸種を変えたり組織を変えることで、見た目に違和感ができるおそれや、着用感が悪くなるおそれがある。
樹脂を付与する方法は樹脂付与領域における布帛の伸縮性を変化させる方法であり、布帛内で自在に応力をコントロールし易いが、樹脂を付与するため布帛の風合が硬くなり易く、着用感は悪くなるおそれがある。また樹脂付与部の通気性低下、繰返し着用時もしくは洗濯による樹脂破壊、割れ、剥がれ等が生じ耐久性が懸念される。
布帛やテープ状物を積層する方法は接着、縫製等の方法を採用するため応力差は得られ易いが、これも接着剤樹脂により風合が硬くなったり、貼付けた部分の厚みが増大することで着用感が損なわれるおそれがある。また、積層した布帛などが剥離するおそれもある。縫製においては縫製部に段差や凹凸が生じ、肌面へのあたりが気になるなどの問題がある。
また、抜蝕加工方法についても多くの技術が開示されてきた。例えば、特開平２−９１２８８号公報および特開平３−８６７号公報には、繊維脆化剤としてアミン類（トリエタノールアミン等）にて処理した繊維布帛シートを更にアルカリ処理することによって、変性ポリエステル繊維をアルカリ加水分解させる抜蝕方法が提案されている。しかしながら、繊維脆化剤としてアミン類を用いる上記の方法は、変性ポリエステル繊維以外の残存させるべき繊維も脆化させてしまい、強度を低下させるため使用できる繊維の種類に制限があった。
更に、抜蝕加工を行った場合、抜蝕部は弾性繊維が布帛の表面に露出しやすくなる。このため太陽光等の紫外線に布帛が暴露されると弾性繊維が脆化して伸縮性の低下を起こすという問題があった。In recent years, high-performance fabrics aimed at functions such as improvement of motor functionality, fatigue recovery function, fatigue reduction function, body shape correction, or body shape correction using various methods have been developed. Development is expanding. One of them is a highly stretchable fabric using elastic fibers such as polyurethane fibers, and these are used in sports and inner fields. These products are products that reduce discomfort at the time of wearing and give necessary stress to necessary parts according to the purpose.
As a technique to generate stress for each required part, a technique to change the weaving and knitting conditions such as changing the fineness and type of yarn used or changing the structure, a method of applying resin to a predetermined part, and a process for removing a predetermined part And a method of laminating a cloth or tape-like material in a predetermined place.
The method of changing the weaving and knitting conditions is easy to obtain a stress difference and easy to control the stress, but changing the fineness of the yarn and the yarn type or changing the structure may cause a sense of incongruity and poor wear. There is a risk.
The method of applying the resin is a method of changing the stretchability of the fabric in the resin application region, and it is easy to control the stress freely in the fabric, but since the resin is applied, the texture of the fabric is likely to be hard, and the feeling of wear is May be worse. In addition, there is a concern about durability due to a decrease in air permeability of the resin-applied part, resin breakage, cracking, peeling, etc. due to repeated wearing or washing.
The method of laminating fabrics and tape-like materials employs methods such as bonding and sewing, so it is easy to obtain a stress difference, but this also makes the texture harder due to the adhesive resin and increases the thickness of the pasted part. There is a risk that the feeling of wearing will be impaired. In addition, the laminated fabric may be peeled off. In sewing, there is a problem that a step or unevenness is generated in the sewing part, and the contact with the skin surface is anxious.
In addition, many techniques have been disclosed for the removal processing method. For example, in JP-A-2-91288 and JP-A-3-867, a modified polyester is obtained by further alkali-treating a fiber fabric sheet treated with amines (such as triethanolamine) as a fiber embrittlement agent. An extraction method for alkali hydrolysis of fibers has been proposed. However, the above method using amines as a fiber embrittlement agent causes embrittlement of fibers other than the modified polyester fiber, and there is a limit to the types of fibers that can be used to reduce the strength.
Furthermore, when performing the erosion process, the erosion part tends to expose the elastic fiber on the surface of the fabric. Therefore, when the fabric is exposed to ultraviolet rays such as sunlight, there is a problem that the elastic fiber becomes brittle and the stretchability is lowered.

本発明の布帛は、ポリエステル系繊維を含む２種以上の非弾性繊維と耐アルカリ性ポリウレタン繊維繊維で構成され、ポリエステル系非弾性繊維が選択的に抜蝕された抜蝕部と非抜蝕部とが形成された布帛であり、好ましくは、非弾性繊維が抜蝕性繊維であるカチオン可染性ポリエステル繊維と非抜蝕性繊維であるナイロン繊維からなり、弾性繊維がエーテル系ポリウレタン繊維からなることを特徴とする伸縮性布帛である。
耐アルカリ性ポリウレタン繊維の耐アルカリ性は、６％濃度の苛性ソーダ水溶液に常温（２０℃）で５分間浸漬後の強度保持率を測定することで確認でき、その値が６０％以上であることが好ましい。
本発明において用いられる非弾性繊維としては、抜蝕されないものと抜蝕されるものの２種類を用いる。
本発明では抜蝕される非弾性繊維としてはカチオン可溶性ポリエステル系繊維が用いられる。常圧タイプまたは高圧タイプのカチオン可染性ポリエステル繊維が好ましいが、抜蝕性に優れる点で、常圧タイプのカチオン可染性ポリエステル繊維が特に好ましい。
抜蝕されない非弾性繊維としては、綿や麻等の天然繊維、ポリエステル繊維やポリアミド繊維等の合成繊維、またはレーヨンなどの再生繊維やセルロースアセテート等の半合成繊維のいずれであっても良く、特に限定されないが、強度係数が１７０，０００以上であるものが用いられる。通常は、ナイロン繊維やポリエチレンテレフタレート繊維が好ましく用いられる。特に、強度、耐久性や染色堅牢度の点でナイロン繊維が好ましい。
本発明では上記の抜蝕性の異なる複数種の非弾性繊維と組合せて弾性繊維を用いるが、弾性繊維としては上記したように耐アルカリ性ポリウレタン弾性繊維が用いられる。
具体的には、耐抜蝕性の点で、６％濃度の苛性ソーダに常温で５分間浸漬後の強度維持率が６０％以上であるポリウレタン繊維を用いることが好ましく、特に、エーテル系ポリウレタン繊維が好ましい。苛性ソーダ浸漬後のポリウレタンの強度保持率が６０％未満であると抜蝕部に必要な応力が得られないおそれがある。
また、本発明で用いる布帛は、抜蝕処理前において、カチオン可染性ポリエステル繊維が３０〜５５％、非抜蝕性非弾性繊維が２５〜５５％、弾性繊維が１０〜３０％の割合で構成されていることが好ましい。カチオン可染性ポリエステルが４５％未満であると非抜蝕部に必要な応力が得られないおそれがあり、５５％より多くなると、抜蝕部と非抜蝕部の応力差が大きくなり着用感が損なわれるおそれがある。
また、抜蝕されない非弾性繊維繊維の割合が２５％未満であると必要な破裂強度が得られないおそれがあり、５５％より多くなると伸縮性が損なわれるおそれがある。
また、弾性繊維の割合が、１０％未満であると必要な応力が得られないおそれがあり、４５％を超えると染色加工時に洗濯堅牢度等の堅牢度が確保できないおそれがある。
また、非抜蝕性非弾性繊維の強度係数は１７０，０００以上であることが必要であり、強度係数が１７０，０００未満であると抜蝕部の破裂強度が十分得られないおそれがある。
更に、抜蝕部の破裂強度は２００ＫＰａ以上であることが好ましい。
本発明で使用される弾性繊維と２種以上の非弾性繊維は、それぞれ単独、混紡、混繊、合撚、交撚、引き揃え糸等の適宜の糸形状で用いることができる。糸の繊度は、特に限定されない。
布帛の形態は、編物、織物などが挙げられるが、特に限定されない。
上述のような構成により得られた布帛に抜蝕処理を行うことにより、抜蝕部と非抜蝕部とが形成された布帛が得られる。抜蝕部は主に弾性繊維と非抜蝕性非弾性繊維からなり、非抜蝕部は、弾性繊維と抜蝕性非弾性繊維と非抜蝕性非弾性繊維から構成される。但し、抜蝕部においても、抜蝕の処理条件を弱くすることにより、抜蝕性非弾性繊維の一部を残すこともできる。
抜蝕処理は、抜蝕性非弾性繊維であるカチオン可染性ポリエステル繊維を抜蝕し、他の構成繊維を抜蝕しない適宜の抜蝕加工剤を布帛に付与することによって行うことができる。
抜蝕加工剤としては、従来から知られた抜蝕加工剤であるグアニジン弱酸塩、フェノール類、アルコール類、アルカリ金属水酸化物、アルカリ土類金属水酸化物などが挙げられる。抜蝕加工剤の濃度は適宜決めることができる。また、抜蝕助剤として第４級アンモニウム塩を用いることもできる。抜蝕加工剤を布帛に付与した後８０〜１７０℃で加熱蒸気にて１〜３０分蒸熱処理を行うことで他の成分にほとんど影響を与えることなく抜蝕すべき非弾性繊維を抜蝕することができる。
布帛への抜蝕加工剤の付与方法としては、浸漬法、パッド・ロール法、カレンダー法、インクジェットプリント法、パッディング法、捺染法、スプレー法などから選ばれる少なくとも１つの方法を用いることができ、抜蝕加工剤含有液が抜蝕したい部分に均一に付与できれば特に限定されない。
本発明では、用いる繊維内部に、更には後加工により抜蝕部と非抜蝕部をもつ伸縮性布帛に、紫外線吸収剤を付与することが好ましい。
特に、弾性繊維として、フェノール系酸化防止剤、または有機系紫外線吸収剤を含んだ状態にて紡糸されたエーテル系ポリウレタン繊維を用いることが好ましい。更には有機系紫外線吸収剤としてベンゾトリアゾール系紫外線吸収剤を使用することが好ましい。フェノール系酸化防止剤、または有機系紫外線吸収剤はポリウレタンの紡糸工程までに添加できればよく、繊維となる樹脂の重合反応に影響を及ぼさない程度に原料に配合しておくこともできる。更に、繊維となる樹脂の重合が完結した後に配合することもできるが、樹脂の重合終了後から紡糸前までの間に配合することが好ましい。紡糸の際に使用する紡糸装置や紡糸条件は、特に限定されるものではなく、樹脂の組成、用途、目的、糸物性などによって公知の任意の方法を選択することができる。
また、構造中に塩素を含むベンゾトリアゾール系紫外線吸収剤を後加工で付与することが好ましい。構造中に塩素を含むベンゾトリアゾール系紫外線吸収剤としては、２−（２’−ヒドロキシ−３’−ｔ−ブチル−５’−メチルフェニル）−５−クロロベンゾトリアゾール、２−（２’−ヒドロキシ−３’，５’−ジ−ｔ−ブチルフェニル）−５−クロロベンゾトリアゾールなどが挙げられる。上記のような塩素を含むベンゾトリアゾール系紫外線吸収剤は、ポリウレタン繊維中のアミノ末端基とイオン結合するため、紫外線による脆化を効果的に抑制することができる。構造中に塩素を含むベンゾトリアゾール系紫外線吸収剤以外の紫外線吸収剤を使用すると、紫外線によるポリウレタン繊維の脆化を十分に抑制できないおそれがある。
上記のベンゾトリアゾール系紫外線吸収剤の付与は、布帛を得た後、任意の工程で行うことができるが、特に、布帛を染色加工する際に、染料と共にベンゾトリアゾール系紫外線吸収剤を付与することが好ましい。その際、ベンゾトリアゾール系紫外線吸収剤は、布帛重量に対して、０．１〜２０．０重量％付与するのが好ましく、特に３．０〜８．０重量％付与するのが好ましい。ベンゾトリアゾール系紫外線吸収剤の付与量が０．１重量％未満であると、紫外線によるポリウレタン繊維の脆化を防止できないおそれがある。また、ベンゾトリアゾール系紫外線吸収剤の付与量が２０．０重量％を超えると、ポリウレタン繊維の高伸縮性が阻害されやすくなったり、或いは布帛を染色しても鮮明な色相を発現しにくくなる傾向が生じる。
上述のように、有機系紫外線吸収剤を紡糸前と製布後の後加工の２度付与することが好ましい。
上記の布帛にベンゾトリアゾール系紫外線吸収剤を付与した後、熱処理を施す。熱処理を施すことにより、ベンゾトリアゾール系紫外線吸収剤はポリウレタン繊維に吸着される。この熱処理は、染色加工後において通常行われる仕上セットの工程で行うことができる。熱処理条件は１００℃以上の温度で数秒〜数分程度の時間行うことが好ましい。
本発明の伸縮性布帛は抜蝕部におけるカーボンアーク灯の４０時間照射後の応力保持率がカーボンアーク照射前の９０％以上であることが好ましい。応力保持率が９０％未満であると、着用時に抜蝕部が破れたり、伸縮性低下を起こし易くなるおそれがある。
また、抜蝕部の３０％伸長時の応力は非抜蝕部の３０％伸長時の応力の２０〜８５％が好ましい。応力比が２０％未満であると締め付け感が得られにくく、伸長後の回復が十分になされていないおそれがあり、運動機能性向上、体型補正などの効果が得られないおそれがある。
応力比が８５％より大きくなると抜蝕部と非抜蝕部の応力差が得られにくく、意図する機能効果が得られなくなるおそれがある。
また、抜蝕部の弾性繊維の破断強度が非抜蝕部の弾性繊維の破断強度の９０％以上であることが好ましい。破断強度比が９０％未満であると着用時に抜蝕部が破れたり、伸縮性低下を起こし易くなるおそれがある。
これらの特性は上記した非処理布帛と抜蝕処理と紫外線吸収剤の組合せにより容易に達成することができる。
本発明の伸縮性布帛は、上記抜蝕部、非抜蝕部の任意の領域に柄および色等が付されたものとすることもできる。The fabric of the present invention is composed of two or more kinds of non-elastic fibers including polyester fibers and alkali-resistant polyurethane fiber fibers, and a discharge portion and a non-discharge portion where the polyester non-elastic fibers are selectively discharged. Preferably, the non-elastic fiber is made of a cationic dyeable polyester fiber, which is an extractable fiber, and a nylon fiber, which is a non-extractable fiber, and the elastic fiber is made of an ether-based polyurethane fiber. A stretchable fabric characterized by
The alkali resistance of the alkali-resistant polyurethane fiber can be confirmed by measuring the strength retention after immersion in a 6% strength aqueous caustic soda solution at room temperature (20 ° C.) for 5 minutes, and the value is preferably 60% or more.
As the inelastic fiber used in the present invention, two types are used, one that is not removed and one that is removed.
In the present invention, a cation-soluble polyester fiber is used as the inelastic fiber to be removed. An atmospheric pressure type or high pressure type cationic dyeable polyester fiber is preferred, but an atmospheric pressure type cationic dyeable polyester fiber is particularly preferred from the viewpoint of excellent dischargeability.
Non-elastic fibers that are not eroded may be any of natural fibers such as cotton and hemp, synthetic fibers such as polyester fibers and polyamide fibers, regenerated fibers such as rayon, and semi-synthetic fibers such as cellulose acetate. Although not limited, those having an intensity coefficient of 170,000 or more are used. Usually, nylon fibers and polyethylene terephthalate fibers are preferably used. In particular, nylon fibers are preferable in terms of strength, durability, and dyeing fastness.
In the present invention, an elastic fiber is used in combination with a plurality of types of non-elastic fibers having different discharging properties. As described above, an alkali-resistant polyurethane elastic fiber is used as the elastic fiber.
Specifically, in terms of corrosion resistance, it is preferable to use a polyurethane fiber having a strength maintenance ratio of 60% or more after being immersed in caustic soda of 6% concentration at room temperature for 5 minutes. preferable. If the strength retention of polyurethane after immersion in caustic soda is less than 60%, the stress required for the removed portion may not be obtained.
In addition, the fabric used in the present invention has a ratio of 30 to 55% of cationic dyeable polyester fiber, 25 to 55% of non-extractable inelastic fiber, and 10 to 30% of elastic fiber before the discharge treatment. It is preferable to be configured. If the cationic dyeable polyester is less than 45%, the stress required for the non-extracted portion may not be obtained. If it exceeds 55%, the difference in stress between the extracted portion and the non-extracted portion becomes large, and the feeling of wear May be damaged.
Moreover, there exists a possibility that required bursting strength may not be acquired when the ratio of the non-elastic fiber fiber which is not discharged is less than 25%, and there exists a possibility that a stretching property may be impaired when it exceeds 55%.
Further, if the proportion of the elastic fiber is less than 10%, a necessary stress may not be obtained, and if it exceeds 45%, fastness such as washing fastness may not be ensured during dyeing.
Further, the strength coefficient of the non-extractable inelastic fiber needs to be 170,000 or more, and if the strength coefficient is less than 170,000, the burst strength of the extracted portion may not be obtained sufficiently.
Furthermore, the burst strength of the extracted portion is preferably 200 KPa or more.
The elastic fiber and the two or more types of non-elastic fibers used in the present invention can be used in an appropriate yarn shape such as single, mixed spinning, mixed fiber, mixed twist, cross-twist, and aligned yarn. The fineness of the yarn is not particularly limited.
Examples of the form of the fabric include a knitted fabric and a woven fabric, but are not particularly limited.
By performing a discharge treatment on the fabric obtained by the above-described configuration, a fabric in which a discharge portion and a non-discharge portion are formed is obtained. The extracted portion is mainly composed of elastic fibers and non-extractable non-elastic fibers, and the non-extracted portion is composed of elastic fibers, extractable inelastic fibers, and non-extractable inelastic fibers. However, part of the extractable inelastic fiber can also be left in the removed portion by weakening the removal treatment conditions.
The discharging process can be performed by discharging a cationic dyeable polyester fiber, which is a discharging inelastic fiber, and applying an appropriate discharging agent that does not discharge other constituent fibers to the fabric.
Examples of the pitting processing agent include guanidine weak acid salts, phenols, alcohols, alkali metal hydroxides, alkaline earth metal hydroxides, and the like, which are conventionally known pitting processing agents. The concentration of the removal processing agent can be appropriately determined. Moreover, a quaternary ammonium salt can also be used as an extraction assistant. After applying the removal processing agent to the fabric, the non-elastic fiber to be discharged is discharged without affecting the other components by performing steam heat treatment at 80 to 170 ° C. for 1 to 30 minutes with heating steam. be able to.
As a method for applying the removal processing agent to the fabric, at least one method selected from a dipping method, a pad / roll method, a calendar method, an ink jet printing method, a padding method, a textile printing method, a spray method, and the like can be used. There is no particular limitation as long as the removal processing agent-containing liquid can be uniformly applied to the portion to be removed.
In the present invention, it is preferable that an ultraviolet absorber is applied to the stretchable fabric having a removed portion and a non-extracted portion by post-processing in the fiber to be used.
In particular, it is preferable to use an ether-based polyurethane fiber spun in a state containing a phenol-based antioxidant or an organic ultraviolet absorber as the elastic fiber. Furthermore, it is preferable to use a benzotriazole ultraviolet absorber as the organic ultraviolet absorber. The phenolic antioxidant or the organic ultraviolet absorber only needs to be added before the polyurethane spinning step, and can be added to the raw material to the extent that it does not affect the polymerization reaction of the resin that becomes the fiber. Furthermore, it can be blended after the polymerization of the resin to be fibers is completed, but it is preferably blended after the polymerization of the resin until before spinning. The spinning apparatus and spinning conditions used for spinning are not particularly limited, and any known method can be selected depending on the resin composition, application, purpose, yarn physical properties, and the like.
Moreover, it is preferable to give the benzotriazole type ultraviolet absorber which contains chlorine in a structure by post-processing. Examples of the benzotriazole ultraviolet absorber containing chlorine in the structure include 2- (2′-hydroxy-3′-t-butyl-5′-methylphenyl) -5-chlorobenzotriazole and 2- (2′-hydroxy). -3 ', 5'-di-t-butylphenyl) -5-chlorobenzotriazole. The benzotriazole-based ultraviolet absorber containing chlorine as described above is ionically bonded to the amino terminal group in the polyurethane fiber, so that embrittlement due to ultraviolet rays can be effectively suppressed. If an ultraviolet absorber other than the benzotriazole-based ultraviolet absorber containing chlorine in the structure is used, there is a possibility that the embrittlement of the polyurethane fiber due to ultraviolet rays cannot be sufficiently suppressed.
The above benzotriazole UV absorber can be applied in any step after the fabric is obtained, and in particular, when the fabric is dyed, the benzotriazole UV absorber is added together with the dye. Is preferred. At that time, the benzotriazole-based ultraviolet absorber is preferably applied in an amount of 0.1 to 20.0% by weight, particularly preferably 3.0 to 8.0% by weight, based on the weight of the fabric. If the applied amount of the benzotriazole-based ultraviolet absorber is less than 0.1% by weight, the polyurethane fiber may not be embrittled by ultraviolet rays. Moreover, when the application amount of the benzotriazole-based ultraviolet absorber exceeds 20.0% by weight, the high stretchability of the polyurethane fiber tends to be inhibited, or even if the fabric is dyed, a clear hue tends not to be expressed. Occurs.
As described above, it is preferable to apply the organic ultraviolet absorber twice before spinning and after processing after fabric production.
After the benzotriazole-based ultraviolet absorber is applied to the fabric, heat treatment is performed. By performing the heat treatment, the benzotriazole ultraviolet absorber is adsorbed on the polyurethane fiber. This heat treatment can be performed in a finishing set process that is normally performed after dyeing. The heat treatment conditions are preferably performed at a temperature of 100 ° C. or higher for a period of several seconds to several minutes.
In the stretchable fabric of the present invention, the stress retention after 40 hours irradiation of the carbon arc lamp in the discharged portion is preferably 90% or more before the carbon arc irradiation. If the stress retention rate is less than 90%, the extracted portion may be torn at the time of wearing, or the stretchability may be easily lowered.
Further, the stress at 30% elongation of the extracted portion is preferably 20 to 85% of the stress at 30% elongation of the non-extracted portion. When the stress ratio is less than 20%, it is difficult to obtain a feeling of tightening, there is a possibility that recovery after stretching may not be sufficiently performed, and there is a possibility that effects such as improvement of motor functionality and correction of body shape may not be obtained.
If the stress ratio is greater than 85%, it is difficult to obtain a stress difference between the extracted portion and the non-extracted portion, and the intended functional effect may not be obtained.
Moreover, it is preferable that the breaking strength of the elastic fiber in the extracted portion is 90% or more of the breaking strength of the elastic fiber in the non-extracted portion. If the rupture strength ratio is less than 90%, there is a possibility that the extracted portion is torn at the time of wearing or the stretchability is liable to be lowered.
These characteristics can be easily achieved by a combination of the above-mentioned non-treated fabric, a discharge treatment, and an ultraviolet absorber.
In the stretchable fabric of the present invention, a pattern, a color, and the like may be added to any region of the above-described discharged portion and the non-extracted portion.
