【０００１】
【発明の属する技術分野】
本発明は着用快適性に優れた吸放湿性布帛及び繊維製品に関するものである。
【０００２】
【従来の技術】
従来、衣服及びその他衣料、作業着用途には綿やレーヨン、酢酸セルロースなどセルロース系繊維が多用されている。該セルロース系繊維は優れた吸湿、吸汗性能を有し着用快適性に優れたものであるが、強度面やW＆W性、染色堅牢度などの性能面は消費者の十分なケアが必要であり、かつ保水性が良好であるために乾き難いなど、様々な消費者クレームが挙げられる現状にある。また、ポリエステルやポリアミド、ポリアクリロニトリル、ポリオレフィンなど合成繊維は天然繊維と比較し強度面やW＆W性、染色堅牢性に優れたものであるが、合繊特有のぬめり感の強い風合いであり吸湿・吸汗性に乏しく蒸れ感、べとつき感を感じるものであった。
【０００３】
上記合成繊維、とりわけポリエステルは価格的に安価であり優れた形態安定性、速乾性を有する素材であるが、ポリエステル１００％からなる商品群は消費低迷、製品価格破壊の影響を受け、残念ながら消費者の購買意欲を掻き立てるものには成り得ていない。ポリエステル表面親水化によって吸湿・吸汗性を付与したもの等、ポリエステルの表面改質素材も多数上市、提案されているが消費者からは一部スポーツ衣料用途や作業着用途等を除いてまだまだ認識されていない現状にあり、綿など天然繊維や再生繊維、半合成繊維との交編織、交撚、混繊、混紡等を施した布帛構造物が上市、提案されている。
【０００４】
布帛構造物全体に対する繊維重量に関して天然繊維や再生繊維、半合成繊維の重量が大きくなると風合いや吸湿・吸汗性は良好なものとなるが、布帛の引裂強度や染色堅牢度、W＆W性等の消費性能面で問題が生じ易く、強度やその他取扱い性能を向上させる為には合成繊維を一定割合以上複合させねばならない。更には速乾性を向上させて従来素材とは相反する性能を与えるためにも疎水性合成繊維、特にポリエステル繊維などを混繊、混紡、合撚、交編織することが望ましいが、以下のような課題が生じる。
【０００５】
ポリエステル繊維など疎水性合成繊維を主体とする組み合せにすると強度面では好適なものに仕上がるが、蒸れ感を感じさせるものになるため親水性合成繊維、取り分け高吸放湿性を有するアクリレート系合成繊維等を適当量組み合せた商品も上市されてきている。しかしながら該アクリレート系繊維は染色性に乏しく布帛表面が白茶けた感じに仕上り、同色性が得られ難いため用途が制約されてしまうという問題を抱えていた。
【０００６】
【発明が解決しようとする課題】
本発明は上記の如き従来の問題を解消し、吸湿・吸汗性に優れ、更には良好な速乾性を有する着用快適性に優れた布帛及び繊維製品を提供することを課題とするものである。より詳細には高吸放湿性アクリレート系繊維を効果的に糸条の芯部を形成させるように複合した糸条を用いることによって布帛表面品位を向上させつつ、衣服内気候その他着用快適性に優れた布帛及び繊維製品を提供することを課題とするものである。
【０００７】
【課題を解決するための手段】
即ち、本発明は以下の構成からなる。
１．高吸放湿性合成繊維、ポリエステル繊維及び親水性繊維を含んで構成される布帛であって、該高吸放湿性合成繊維、該ポリエステル繊維が布帛重量のうち、それぞれ３重量％以上２０重量％以下、４５重量％以上８５重量％以下を占めてなり、高吸放湿性合成繊維が架橋型アクリレート系繊維であり、布帛を構成する糸条は架橋アクリレート系繊維が芯部を構成しポリエステル繊維及び親水性繊維が周囲をラッピングしており、且つ下記の（１）〜（３）の要件を満足することを特徴とする吸放湿性に優れた布帛。
（１）２０℃、６５％ＲＨ環境と３０℃、９０％ＲＨ環境下の吸湿量差（ΔＷ）が１．０％以上
（２）発汗時の衣服内湿度が７０％ＲＨ以下
（３）滴下法による吸水速度が１秒以下
２．生地目付が１００〜３５０ｇ／ｍ２、フラジール法による通気度が１．５ｃｃ／ｃｍ２・ｓｅｃ．以上である上記第１に記載の吸放湿性に優れた布帛。
３．親水性繊維が獣毛、綿、レーヨン、セルロースアセテート、ポリノジック、ポリアミド、プロミックスの各繊維から選択される少なくとも１種類の繊維であり、前記親水性繊維を含んで構成された複合紡績糸の単糸、若しくは長短複合紡績糸の単糸が下記式（４）で示される撚係数Ｋ１で加撚されており、単糸、双糸、三子撚の何れか、若しくは組み合せで製織編されてなることを特徴とする上記第１又は第２に記載の吸放湿性に優れた布帛。
（４）２．５≦Ｋ１≦６．０
但し、Ｋ１＝Ｔ１／√Ｎであり、Ｔ１は撚数（回／吋）、Ｎは英式綿番手を示す。
４．親水性繊維がレーヨン、セルロースアセテート、ポリアミド、プロミックスから選択される少なくとも１種類である長短複合カバリング糸を用いて製織編されてなり、該長短複合カバリング糸を構成する最外層に位置する糸が下記式（５）で示される撚係数Ｋ２を有することを特徴とする上記第１又は第２に記載の吸放湿性に優れた布帛。
（５）撚係数Ｋ２；３５００≦Ｋ２≦２５０００
但し、Ｋ２＝Ｔ２×（Ｄ×０．９０）１／２であり、Ｔ２は撚数（回／ｍ）、Ｄは長短複合カバリング糸の総繊度（デシテックス）を示す。
５．上記第１〜第４のいずれかに記載の吸放湿性に優れた布帛を少なくとも一部に用いてなることを特徴とする繊維製品。
【０００８】
以下、本発明を詳述する。
本発明の吸放湿性に優れた布帛は、高吸放湿性合成繊維を少なくとも一部に含んでなり、２０℃、６５％RH環境と３０℃、９０％RH環境下の吸湿量差(ΔW)は１．０％以上であることが好ましい。より好ましくは２．０％以上、更に好ましくは２．５％以上である。該吸湿量差(ΔW)が１．０％未満では吸湿性に乏しく、発汗に伴う水蒸気を衣服外に逃がすことが出来ないため、蒸れ感を感じるものになってしまい、着用快適性を満足させづらくなるため好ましくない。
【０００９】
本発明の吸放湿性に優れた布帛の発汗時の衣服内湿度は７０％RH以下であることが好ましく、より好ましくは６５％以下である。該衣服内湿度が７０％RHを超えると高湿度環境では蒸れ感、不快感を感じるものになってしまうため好ましくない。通常、発汗時には多量の水蒸気成分を衣服と肌の間の空間に排出するが、該衣服内湿度を７０％RH以下に保つことによって着用時の不快感を伴わない布帛とすることが可能となる。
【００１０】
また本発明の吸放湿性に優れた布帛の滴下法による吸水速度は１秒以下であることが好ましい。吸水速度が１秒を超える長い時間を要するものとなれば、汗腺から排出された液状汗を瞬時に吸収することが出来ず、長時間肌面に残存し不快感を伴うものになってしまう他、水分が生地に拡散する拡散速度も小さいものになってしまうため、生地の乾燥速度が小さくなり好ましくないのである。
【００１１】
本発明の吸放湿性に優れた布帛の少なくとも一部に含有される高吸放湿性合成繊維は、高吸放湿性架橋型アクリレート系繊維であることが好ましい。該高吸放湿性架橋型アクリレート系繊維の布帛全体に対する含有量（重量分率）については３重量％以上２０重量％以下であることが好ましく、より好ましくは５重量％以上１５重量％以下である。該高吸放湿性架橋型アクリレート系繊維の重量分率が３重量％未満であれば、高い吸放湿性能を付与することが困難で、着用時の蒸れ感を感じるものとなってしまうため好ましくない。また、２０重量％を超過すると該高吸放湿性架橋型アクリレート系繊維の染色性が乏しいため、黒や紺など濃色系色目では布帛の同色性が得にくく、白茶けた表面感となり、しかも強度の必ずしも十分でない該繊維を多用することにより、引裂強度その他強度面で実用に供するものにはなり難いため好ましくない。
【００１２】
また、本発明の布帛を構成する糸条はポリエステル繊維を４５重量％以上８５重量％以下含有していることが好ましく、より好ましくは５０重量％以上７５重量％以下である。該ポリエステル繊維はステープルファイバー(短繊維)であってもフィラメント(長繊維)であってもよく、双方が含まれていても構わない。また、フィラメントの場合は仮撚加工糸など微細捲縮を有する糸条やシックアンドシン糸等であってもよい。更には、該ポリエステル繊維の熱収縮率についても一定のもの以外に収縮特性が異なる二種以上の繊維を組み合せて使用することも出来る。特に、熱伸長特性を有するポリエステルと熱収縮特性を有するポリエステルを組み合わせることによって膨らみ感に優れ、尚且つ架橋型アクリレート系繊維の被覆性を向上させた糸条とすることが可能となり好ましい。ポリエステル繊維含有量が４５重量％未満の範囲ではＷ＆Ｗ性や寸法安定性、強度的に優れた商品に仕上げることが出来にくく、８５重量％を超過する範囲ではポリエステル繊維特有のヌメリ感を伴うものになる他、布帛の吸放湿性能が低いものに留まり、高吸放湿性、Ｗ＆Ｗ性、強度的に優れた商品にはしづらいため好ましくない。
【００１３】
また、該ポリエステル繊維、架橋型アクリレート系繊維以外の構成繊維として、獣毛、綿、ビスコースレーヨン、銅アンモニアレーヨン、ポリノジック、セルロースアセテート、ポリアミド、プロミックス等の繊維からなるステープルファイバー、フィラメントを使用することも好ましい。勿論二種類以上の組み合せも包括される。
【００１４】
本発明の吸放湿性に優れた布帛のフラジール法による通気度は１．５ｃｃ／ｃｍ2・ｓｅｃ．以上であることが好ましい。勿論、通気度が１．５ｃｃ／ｃｍ2・ｓｅｃ．未満の値であっても吸放湿性繊維のベンチレーション機能により汗の水蒸気を衣服外に放出することが可能であるが、通気度が高い方がより換気効率が向上する。発汗時の着用快適性も考慮すると該通気度は１．５ｃｃ／ｃｍ2・ｓｅｃ．以上、より好ましくは３．０ｃｃ／ｃｍ2・ｓｅｃ．以上である。
【００１５】
本発明の吸放湿性に優れた布帛が紡績糸及び／又は長短複合紡績糸を用いて製織編されている場合には、該紡績糸の単糸や長短複合紡績糸の単糸はＴ１を撚数（回／吋）、Ｎを英式綿番手とする時、Ｔ１／√Ｎで定義される撚係数Ｋ１が２．５以上、６．０以下で加撚されており、単糸、双糸、三子撚の何れか、若しくは組み合せで製織編されていることが望ましい。長短複合紡績糸を用いる場合には、長繊維が芯部を構成する一部に使用されていてもよいし、鞘部の一部又は全部に使用し、短繊維の素抜けを防止させる効果を狙うことも出来る。
【００１６】
紡績糸は単糸のみならず、双糸或いは三子撚であってもよく、それらの組み合せで製織編されていてもよい。双子及び三子撚にする場合はＫ１で示した単糸の撚糸を施した後、該加撚された単糸を引き揃え、該撚糸方向の逆方向にK1より甘い撚りを掛けて使用することが望ましい。単糸の撚係数Ｋ１が２.５未満の場合には、紡績糸や長短複合紡績糸の構成繊維の素抜けやピリングが発生しやすくなる他、布帛の引裂強度も十分なものにはならないため好ましくない。また、染色性の悪い高吸放湿性架橋型アクリレート系繊維の被覆性が不満足なものとなり、外観品位も損なわれ易いため好ましくない。また撚係数K1が６.０を超える範囲ではドレープ性のない硬い風合いのものとなってしまい好ましくない。
【００１７】
本発明の布帛の生地目付としては１００〜３５０ｇ／ｍ2の範囲であることが好ましく、より好ましくは１００〜２５０ｇ／ｍ2の範囲が一般衣料用途として好適に使用される。該生地目付が３５０ｇ／ｍ2を超過する厚地(重衣料)では吸放湿性に乏しくなる他、ドレープ性の欠如、肩こりなど血行不良の要因ともなり好ましくない。また１００ｇ／ｍ2未満の薄地では使用する糸条の繊度を小さく抑える必要がありコスト的に好ましくない。繊度を小さくするかわりに織編物の糸密度を粗くすることも可能であるがスリップや縫目滑脱の低下を誘発し好ましいものではない。
【００１８】
本発明の布帛がカバリング糸の形態である長短複合糸条を用いて製織編されている場合、該カバリング糸の最外層を形成する糸の撚係数Ｋ２（＝Ｔ２×（Ｄ×０．９０）1/2）が３５００以上、２５０００以下であることが好ましい（但し、Ｔ２は最外層を形成する糸の撚数（回／ｍ）、Ｄは長短複合カバリング糸の総繊度(デシテックス)を示す。）撚係数Ｋ２が３５００未満の場合、布帛は偏平な膨らみ感を感じないものに仕上がってしまうこと、ピリングが生じやすく消費性能的に満足なものにはならないことの他、高吸放湿性アクリレート系繊維の被覆性が悪く、染色生地は白茶けた外観を有するものになってしまうことから好ましくない。また、撚係数Ｋ２が２５０００を超過する超強撚の範囲では布帛のざらつき感のある粗硬な風合いとなってしまうため好ましくない。
【００１９】
本発明の吸放湿性に優れた布帛は織編物で構成され、組織や製織編機構は特に限定されるものではない。用途に応じてパイル組織やその他二重組織とし、肌側への接触面積を大きくし吸放湿性を向上させることや嵩高性向上により含気量を大きくし、保温性、外気遮温性を保持することも好適である。製織編に使用する織機、編機についても特に限定されるものではなく公知技術で実施することが出来る。また針布、サンディング等の方法を用いて表面及び／又は肌面を起毛することも好ましく行うことができる。
【００２０】
製織編された布帛は染色を施されるが、浸染、捺染以外に糸染め、チーズ染めによってマルチカラーミックス効果を付与することも出来る。浸染、捺染ともポリエステル繊維、その他天然繊維などを染色するため、多種染料使いによる多浴染めも好適に採用することが出来る。染色時は特に分散染料など余分な染料を排除するために十分な還元洗浄、湯洗いを実施することが染色堅牢度的に有効である。また綿やポリアミドなどを染色する場合には必要に応じてフィックス剤を処方することが染色堅牢度的に好ましいといえる。
【００２１】
本発明において好ましく使用できる高吸放湿性架橋型アクリレート系繊維は吸放湿性に優れるものの、染色性に乏しいため、該高吸放湿性架橋型アクリレート系繊維がステープル、フィラメントの何れの形態であっても糸条の芯部を形成させることが望ましい。該架橋型アクリレート系繊維を積極的に芯部に導入する方法としては精紡交撚法やコアヤーン法の他、コンベンショナルなカバリング法等が挙げられる。何れの場合も該高吸放湿性架橋型アクリレート系繊維が芯部を形成するようにスライバーやローバー、フィラメント等の供給率、組み合せ、導入糸道を適宜調整することが望ましく、特にカバリングの場合はダブルカバリングとし、上撚方向と下撚方向を逆方向に設定すると残留トルクを小さくすることが出来る。
【００２２】
本発明の布帛を構成する繊維糸条に好適に含めて使用できる架橋型アクリレート系吸放湿発熱繊維について述べる。出発原料としてアクリロニトリルを４０重量％以上、好ましくは５０重量％以上含有するポリアクリロニトリルが好ましく、構成単位はアクリロニトリル単量体、若しくはアクリロニトリル単量体と他の単量体との共重合物の何れであってもよい。アクリロニトリル単量体以外の他の単量体としては例えばハロゲン化ビニル、ハロゲン化ビニリデン、アクリル酸エステル、メタリルスルホン酸、パラスチレンスルホン酸などのスルホン酸含有単量体およびその塩、メタアクリル酸、イタコン酸などのカルボン酸含有単量体およびその塩、アクリルイミド、スチレン、酢酸ビニルなどの単量体が例示されるが、アクリロニトリルと共重合可能な単量体であれば特に限定されるものではない。
【００２３】
上記のアクリル系繊維に水加ヒドラジン、硫酸ヒドラジン、塩酸ヒドラジン、臭素酸ヒドラジン、ヒドラジンカーボネート等のヒドラジン化合物やエチレンジアミン、硫酸グアニジン、塩酸グアニジン、燐酸グアニジン、メラミンその他アミン基を複数個有する化合物を用いて分子間、分子内架橋を行う。この架橋反応はヒドラジン化合物が加水分解反応により架橋されずに残存した状態の二トリル基を実質的に消失させるとともに１．０〜４．５ｍｅｑ／ｇの塩型カルボキシル基と残部にアミド基を導入する方法であり、具体的にはアルカリ金属の水酸化物などの塩基性水溶液や硝酸、硫酸、塩酸などの強酸水溶液を含浸させるか、その水溶液中に原料繊維(アクリル系繊維)を浸漬した状態で加熱処理する方法、或いは上記架橋剤の導入と同時に加水分解を起こさせる方法によって架橋型アクリレート系繊維を得ることが例示される。
【００２４】
上記架橋構造の定量法としては、ヒドラジン系化合物を架橋剤として導入した後の架橋型アクリレート系繊維の窒素含有量と原料繊維であるアクリル系繊維の窒素含有量との差、すなわちヒドラジン系化合物導入による窒素含有量増加を評価することが好ましい。ヒドラジン系化合物による架橋構造導入については高吸放湿性を付与するために該窒素含有量増加を１.０〜１０.０重量％に調整することが望ましく、ヒドラジン系化合物濃度を５〜６０重量％とし処理温度５０〜１２０℃で処理する方法等が好適に用いられる。該窒素含有量増加が１.０重量％未満であれば架橋型アクリレート系繊維に対する架橋構造導入が少なすぎるため、強度的に満足し得るものになりにくいため好ましくない。また該窒素含有量増加が１０.０重量％を超過する範囲では高い吸放湿性能を付与することが出来づらく好ましくない。
【００２５】
繊維の断面形状に関しては特に限定を加えるものではなく、公知の断面の組み合せで用途や目的に応じて適宜選択することが出来る。特に吸水・吸汗性能を向上させる為に糸条長手方向にスリット(溝)を有する断面や異型度の大きい断面（マルチローバル断面を含む）等を採用すると、繊維表面の濡れ性が向上し、より好ましい。本発明布帛を構成する糸条繊度も特に限定されるものではないが、一般衣料用途を考慮すると大略５０〜５００デシテックス（英式綿番手で１２〜１２０番）程度の範囲が好適に採用される。勿論、単繊維繊度についても特に限定を加えるものではない。
【００２６】
次に、本発明の繊維製品について述べる。本発明の繊維製品は、本発明の吸放湿性に優れた布帛を少なくとも一部に用いてなることが必要である。本発明の繊維製品は吸湿、吸汗性に優れ、良好な速乾性を有する着用時に快適なものである。繊維製品は紳士用、婦人用のインナーやアウターの衣服、帽子、手袋、ソックスなどであり、特にスカート、パンツ、スラックス、ジャケットなどを代表例として挙げることができるが、これらに限定されるものではない。

BACKGROUND OF THE INVENTION
The present invention relates to a moisture-absorbing / releasing fabric and a textile product excellent in wearing comfort.
[0002]
[Prior art]
Conventionally, cellulosic fibers such as cotton, rayon, and cellulose acetate have been frequently used for clothes and other apparel and work clothes. The cellulosic fiber has excellent moisture absorption and sweat absorption performance and is excellent in wearing comfort, but performance aspects such as strength, W & W property, and dyeing fastness need sufficient care of consumers. In addition, there are various consumer complaints such as difficulty in drying due to good water retention. In addition, synthetic fibers such as polyester, polyamide, polyacrylonitrile, and polyolefin are superior in strength, W & W, and dyeing fastness compared to natural fibers. It was a little stuffy and sticky.
[0003]
The synthetic fiber, especially polyester, is a low-priced material with excellent shape stability and quick-drying, but the product group consisting of 100% polyester is unfortunately consumed due to sluggish consumption and product price destruction. It can't be something that motivates consumers to purchase. Many surface modification materials for polyester have been put on the market and proposed, such as those with moisture absorption and sweat absorption by hydrophilization of the polyester surface, but are still recognized by consumers except for some sports clothing and work clothes. Currently, fabric structures such as cotton, natural fibers such as cotton, recycled fibers, semi-synthetic fibers, knitted fabrics, knitted yarns, blended fibers, blended fibers, etc., have been put on the market and proposed.
[0004]
When the weight of natural fiber, regenerated fiber, and semi-synthetic fiber is increased with respect to the fiber weight of the entire fabric structure, the texture, moisture absorption and sweat absorption properties are improved, but the consumption of the tear strength, dyeing fastness, W & W property, etc. of the fabric In terms of performance, problems are likely to occur, and in order to improve strength and other handling performance, synthetic fibers must be combined in a certain ratio or more. Furthermore, in order to improve the quick drying property and to give the performance contrary to the conventional material, it is desirable to mix, blend, spin, and knit the hydrophobic synthetic fiber, especially polyester fiber. Challenges arise.
[0005]
If the combination is mainly composed of hydrophobic synthetic fibers such as polyester fiber, it will be suitable in terms of strength, but it will make you feel stuffy, so hydrophilic synthetic fibers, especially acrylate synthetic fibers with high moisture absorption and release properties, etc. There are also products on the market that combine appropriate amounts.

If the humidity in the clothes exceeds 70% RH, the feeling of stuffiness and discomfort may be felt in a high humidity environment. Usually, when sweating, a large amount of water vapor component is discharged to the space between the clothes and the skin. By keeping the humidity in the clothes at 70% RH or less, it becomes possible to make the cloth without discomfort during wearing. .
[0010]
Moreover, it is preferable that the water absorption speed | rate by the dripping method of the fabric excellent in the moisture absorption / release property of this invention is 1 second or less. If the water absorption speed takes a long time exceeding 1 second, the liquid sweat discharged from the sweat glands cannot be absorbed instantaneously, and it remains on the skin surface for a long time and causes discomfort. The diffusion rate of moisture diffusing into the dough becomes small, which is not preferable because the drying rate of the dough becomes small.
[0011]
The highly hygroscopic synthetic fiber contained in at least a part of the fabric excellent in hygroscopic property of the present invention is preferably a highly hygroscopic and cross-linked acrylate fiber. The content (weight fraction) of the highly moisture-releasing and cross-linking acrylate fiber to the entire fabric is preferably 3% by weight to 20% by weight, and more preferably 5% by weight to 15% by weight. . If the weight fraction of the highly moisture-absorbing / releasing cross-linked acrylate fiber is less than 3% by weight, it is difficult to impart high moisture-absorbing / releasing performance, and a feeling of stuffiness at the time of wearing will be felt. Absent. On the other hand, if the amount exceeds 20% by weight, the highly moisture-absorbing and cross-linking acrylate fiber has poor dyeability, so it is difficult to obtain the same color of the fabric in dark colors such as black and amber, and the surface becomes white-brown and strong. It is not preferable to use a large amount of the fiber, which is not necessarily sufficient, because it is difficult to be practically used in terms of tear strength and other strength.
[0012]
Moreover, it is preferable that the yarn which comprises the fabric of this invention contains 45 to 85 weight% of polyester fibers, More preferably, it is 50 to 75 weight%. The polyester fiber may be a staple fiber (short fiber) or a filament (long fiber), and both of them may be contained. In the case of a filament, it may be a yarn having a fine crimp such as false twisted yarn or a chic and thin yarn. Further, two or more kinds of fibers having different shrinkage characteristics can be used in combination other than a certain one with respect to the thermal shrinkage rate of the polyester fiber. In particular, it is preferable to combine a polyester having a heat extension property and a polyester having a heat shrink property, so that a yarn having excellent swelling feeling and having improved coverage of a cross-linked acrylate fiber can be obtained. When the polyester fiber content is less than 45% by weight, it is difficult to produce a product with excellent W & W properties, dimensional stability, and strength, and when it exceeds 85% by weight, the polyester fiber has a unique slime. In addition, it is not preferable because the fabric has only a low moisture absorption / release performance and is difficult to produce a product with high moisture absorption / release properties, W & W properties, and strength.
[0013]
In addition, staple fibers and filaments made of fibers such as animal hair, cotton, viscose rayon, copper ammonia rayon, polynosic, cellulose acetate, polyamide, and promix are used as constituent fibers other than the polyester fiber and the cross-linked acrylate fiber. It is also preferable to do. Of course, combinations of two or more types are also included.
[0014]
The air permeability according to the Frazier method of the fabric excellent in moisture absorption and desorption of the present invention is 1.5 cc / cm 2 ・ Sec. The above is preferable. Of course, the air permeability is 1.5cc / cm 2 ・ Sec. Even if it is less than the value, it is possible to release the water vapor of sweat from the clothes by the ventilation function of the hygroscopic fibers, but the ventilation efficiency is improved when the air permeability is higher. The air permeability is 1.5 cc / cm considering the wearing comfort when sweating. 2 ・ Sec. Or more, more preferably 3.0 cc / cm 2 ・ Sec. That's it.
[0015]
When the fabric excellent in moisture absorption / release properties of the present invention is woven and knitted using spun yarn and / or long / short composite spun yarn, the spun yarn or the long / short composite spun yarn is twisted by T1. Number (times / 吋), where N is the English cotton count, the twist coefficient K1 defined by T1 / √N is twisted at 2.5 or more and 6.0 or less, and single yarn, twin yarn It is desirable to be woven or knitted by any one or combination of triplets. When long and short composite spun yarn is used, the long fibers may be used in a part of the core part, or used for a part or all of the sheath part, and the effect of preventing the short fibers from being pulled out. You can also aim.
[0016]
The spun yarn may be not only a single yarn but also a twin yarn or a triple-twist, and may be woven or knitted by a combination thereof. In the case of twin and triplet twisting, after twisting the single yarn indicated by K1, the twisted single yarns are aligned and used with a twist that is sweeter than K1 in the opposite direction of the twisting direction. Is desirable. When the twist coefficient K1 of the single yarn is less than 2.5, the fibers constituting the spun yarn and the long and short composite spun yarn are likely to come off and pilling, and the tear strength of the fabric is not sufficient. It is not preferable. In addition, the coating properties of the highly moisture-absorbing / releasing crosslinked acrylate fiber having poor dyeability are unsatisfactory, and the appearance quality is easily impaired, which is not preferable. In addition, when the twist coefficient K1 exceeds 6.0, it is not preferable because it has a hard texture without drape.
[0017]
The fabric weight of the fabric of the present invention is 100 to 350 g / m. 2 The range is preferably 100 to 250 g / m. 2 This range is suitably used for general clothing applications. The fabric basis weight is 350 g / m 2 Thick ground (heavy clothing) exceeding the range is unfavorable due to poor moisture absorption and release as well as poor blood circulation such as lack of drape and stiff shoulders. 100g / m 2 If the thickness is less than 1, the fineness of the yarn to be used must be kept small, which is not preferable in terms of cost. It is possible to increase the yarn density of the knitted or knitted fabric instead of reducing the fineness, but this is not preferable because it induces a decrease in slip or slippage.
[0018]
When the fabric of the present invention is woven and knitted using long and short composite yarns in the form of covering yarn, the twist coefficient K2 of the yarn forming the outermost layer of the covering yarn (= T2 × (D × 0.90)) 1/2 ) Is preferably 3500 or more and 25000 or less (where T2 is the number of twists (times / m) of the yarn forming the outermost layer, and D is the total fineness (decitex) of the long and short composite covering yarn). If K2 is less than 3500, the fabric will be finished to a flat sensation of swell, and it will not be satisfactory in terms of consumption performance due to pilling, and it will also be coated with highly hygroscopic acrylate fiber This is not preferable because the dyed fabric has a white-brown appearance. Moreover, in the range of the super strong twist in which the twist coefficient K2 exceeds 25000, it becomes unfavorable because it becomes a rough and hard texture with a feeling of roughness of the fabric.
[0019]
The fabric excellent in moisture absorption / release properties of the present invention is composed of a woven or knitted fabric, and the structure and the weaving / knitting mechanism are not particularly limited.

The weaved and knitted fabric is dyed, but in addition to dip dyeing and printing, yarn dyeing and cheese dyeing can also give a multi-color mix effect. Since both dyeing and printing dye polyester fibers and other natural fibers, multi-bath dyeing using various dyes can be suitably employed. When dyeing, it is effective in terms of color fastness to carry out sufficient reduction washing and hot water washing in order to eliminate extra dyes such as disperse dyes. In addition, when dyeing cotton, polyamide or the like, it can be said that it is preferable in terms of dyeing fastness to prescribe a fixing agent as necessary.
[0021]
The highly moisture-absorbing / releasing crosslinked acrylate fiber that can be preferably used in the present invention is excellent in moisture-absorbing / releasing properties, but has poor dyeability. Therefore, the highly moisture-absorbing / releasing crosslinked acrylate fiber is in any form of staple or filament. It is also desirable to form the core of the yarn. Examples of a method for positively introducing the crosslinked acrylate fiber into the core include a spinning and twisting method, a core yarn method, and a conventional covering method. In any case, it is desirable to appropriately adjust the supply rate, combination, and introduction yarn path of the sliver, rover, filament, etc. so that the highly moisture-absorbing / releasing crosslinked acrylate fiber forms a core, particularly in the case of covering. When double covering is used and the upper twist direction and the lower twist direction are set in opposite directions, the residual torque can be reduced.

Intermolecular and intramolecular crosslinking is performed. This cross-linking reaction substantially eliminates the nitrile group remaining in the state where the hydrazine compound is not cross-linked by the hydrolysis reaction, and introduces 1.0 to 4.5 meq / g salt-type carboxyl group and an amide group in the remainder. Specifically, a basic aqueous solution such as an alkali metal hydroxide or a strong acid aqueous solution such as nitric acid, sulfuric acid or hydrochloric acid is impregnated, or raw fiber (acrylic fiber) is immersed in the aqueous solution. It is exemplified that the crosslinked acrylate fiber is obtained by the method of heat treatment with the above-mentioned method or the method of causing hydrolysis simultaneously with the introduction of the crosslinking agent.

Regarding the introduction of a crosslinked structure by a hydrazine compound, it is desirable to adjust the nitrogen content increase to 1.0 to 10.0% by weight in order to impart high moisture absorption and desorption, and the hydrazine compound concentration is 5 to 60% by weight. A method of processing at a processing temperature of 50 to 120 ° C. is preferably used. If the increase in the nitrogen content is less than 1.0% by weight, the introduction of a crosslinked structure into the crosslinked acrylate fiber is too small, and it is difficult to achieve satisfactory strength. Further, it is not preferable because it is difficult to impart high moisture absorption / release performance in the range where the increase in nitrogen content exceeds 10.0% by weight.
[0025]
The cross-sectional shape of the fiber is not particularly limited, and can be appropriately selected depending on the application and purpose by combining known cross-sections.
