Description

【００２８】
本発明による織物（Ａ１）は、風合が柔らかく、耐水圧も高い数値を示し、樹脂コーティング無しでも、傘地として使用できるものであった。これに対して織物（Ｂ１）は通常のポリエステル織物（Ｃ１）に比べると耐水圧は高くなったが、その値は傘地等への使用には不十分であり、また、染色加工による皺が残り、風合も硬くなり、実用性あるものではなかった。
【００２９】
〔実施例２〕
下記の３種の原糸を準備した。
原糸（ａ２）−イソフタル酸（ＩＰＡ）が酸成分の２５モル％を占め、ＤＳＣ法による測定で、実質的に融点ピークを有しない、軟化点約１５０℃の共重合ポリエチレンテレフタレートを芯とし、酸成分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘とする、芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、５０ｄ／１２ｆの糸とした。
原糸（ｂ２）−原糸（ａ２）の芯成分と鞘成分を逆にした５０ｄ／１２ｆの糸。
原糸（ｃ２）−酸成分がテレフタル酸１００％であるレギュラーポリエステルの５０ｄ／１２ｆの糸。
【００３０】
これら３種の原糸を、酸成分がテレフタル酸１００％であるレギュラーポリエステルの５０ｄ／４８ｆ原糸を経糸とした織物の緯糸に使用し、加工揚がりの経緯糸密度が１７５本／in×１０５本／inとなるように平織物（Ａ２，Ｂ２，Ｃ２）を製織し、これら布帛を通常のポリエステル平織物の加工と同様の工程及び条件で染色（液流型染色機）、仕上げ加工した。次に、このようにして得た染色布帛にフッ素系撥水剤を用いて通常の撥水加工を施した。
【００３１】
撥水加工後の各布帛の形態安定性を測定した結果、及び撥水加工後、１６０℃で加圧熱処理した布帛の耐水圧と形態安定性の測定結果を表２に示す。

（２）ウレタンカバリング糸および表面平滑性布帛の説明
非晶質逆転芯鞘型複合繊維は、ウレタン弾性体とともに使用して、スポーツウェア等に用いることもできる。この場合、ウレタン弾性糸は通常使用されているもので良い。弾性糸に使用するウレタン樹脂はポリエステル系であってもポリエーテル系であっても良いが、後の工程での熱処理時間が長く耐熱性を上げることが必要となるような場合はより耐熱性に優れたポリエステル系のポリウレタンを使用することが好ましい。ポリウレタン繊維の紡糸方法についても特に限定をされるものではなく、溶融紡糸、乾式紡糸など通常の方法が好適に用いられる。
【００３４】
これら繊維を用いて織編物とする方法として具体的にはウレタン弾性糸を芯糸とし非晶質逆転芯鞘型複合繊維を鞘糸とするカバリング糸を製造しこれを用いて織編物とする方法、非晶質逆転芯鞘型複合繊維とウレタン弾性糸の双方を同時に用いた織編物とする方法、非晶質逆転芯鞘型複合繊維とウレタン弾性糸の混繊加工糸として織編物とする方法などを用いることができる。
【００３５】
ウレタン弾性糸を芯糸とし非晶質逆転芯鞘型複合繊維を鞘糸としたカバリング糸を用いる場合、カバリング糸の製造方法は通常用いられている方法を好適に使用することができ、カバリング時の鞘糸の巻き付けは一重でも二重であっても良い。さらにこのような複合混繊糸は織物としても編物としても良く、織編物の製造方法も限定されない。
【００３６】
非晶質逆転芯鞘型複合繊維とウレタン弾性糸の双方を同時に用いた織編物を製造する方法としては、公知の方法を好適に用いることができ、必要とする形態安定性と伸縮性から望ましい織編の形態を選択することができる。具体的には非晶質逆転芯鞘型複合繊維とウレタン弾性糸を同時に用いる通常の経編、緯編の交編または交織や、非晶質逆転芯鞘型複合繊維を用いた経組織とウレタン弾性糸を用いた緯組織からなる編物組織などが挙げられる。
【００３７】
非晶質逆転芯鞘型複合繊維とウレタン弾性糸の混繊加工糸の製造方法も公知の方法を用いることができる。具体的には、複合繊維からなる加工糸にウレタン弾性糸を合糸する方法、複合繊維とウレタン弾性糸とを合糸した後仮撚加工を施して加工糸とする方法などが挙げられる。さらにこのような複合混繊糸は織物としても編物としても良く、織編物の製造方法も限定されない。
【００３８】
更に、本発明の表面平滑性を有する布帛は、前記方法により得た織編物に対して、加熱加圧処理を行い、表面を平滑化したものである。表面平滑性の優れたスポーツウェアとするためには、このような処理を施し、複合繊維の断面を偏平な形状に変形し、織編物の持つ表面の膨らみを減少させ、かつ隙間をつめることが必要である。尚、加熱加圧処理は通常用いられるような方法、たとえばカレンダー加工等により行うことができる。
【００３９】
このような加熱加圧処理の際の加熱温度は１５０℃〜２００℃、さらには１６０℃〜１８０℃であることが好ましい。非晶質逆転芯鞘型複合繊維は芯部が低融点、低結晶性の成分であるため、低い温度で繊維断面形状を変形させることが可能となり、加熱処理工程におけるウレタン弾性糸の熱劣化を著しく減少させることとなり、好ましいものである。２００℃より高温で加熱した場合は、ウレタン弾性糸の熱劣化が起こったり、非晶質逆転芯鞘型複合繊維の鞘成分の溶融により芯成分が外に露出して布帛の風合いを損ねることとなるため好ましくない。また、１５０℃未満での加熱加圧処理では十分に糸形状が変形せず、十分な平滑性が得られない。
【００４０】
〔実施例３〕
各物性値は下の方法にて測定した。
耐水圧：ＪＩＳ Ｌ−１０９２Ａ法（静水圧法）
軟化点：ＪＩＳ Ｋ−７１９６法
交編トリコットの製造：イソフタル酸が酸成分の２５モル％を占め、ＤＳＣ法による測定で実質的に融点を有しない、軟化点が１９７℃である共重合ポリエチレンテレフタレートを芯とし、酸成分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘とする、芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、４５ｄ／１０ｆの糸とし、ついで仮撚加工を施し加工糸とした。このような加工糸と４０ｄのウレタン弾性糸を用い交編トリコットとした。
【００４１】
〔実施例４〕
カバリング糸の製造：イソフタル酸が酸成分の２５モル％を占め、ＤＳＣ法による測定で実質的に融点を有しない、軟化点が１９７℃である共重合ポリエチレンテレフタレートを芯とし、酸成分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘とする、芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、５０ｄ／１２ｆの糸とし、インターレースを付与した後、捲き取った。次に２０ｄのウレタン弾性糸を芯糸とし、上記複合繊維を鞘糸として下表の条件にてシングルカバリング糸を製造した。
【００４２】
【表３】

上記カバリング糸を用いて、常法に従ってトリコット編物を製造した。
【００４３】
〔実施例５〕
混繊加工糸の製造方法：イソフタル酸が酸成分の２５モル％を占め、ＤＳＣ法による測定で実質的に融点を有しない、軟化点が１９７℃である共重合ポリエチレンテレフタレートを芯とし、酸成分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘とする、芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、３０ｄ／１０ｆの糸とした。上記複合繊維と２０ｄのウレタン弾性糸を用い、表４の条件で混繊複合加工糸とした。
【００４４】
【表４】

上記混繊糸を用い、常法に従ってトリコット編物を製造した。
【００４５】
上記の実施例３〜５の方法にて製造した伸縮性編物に、圧力７００ｍｍＨ₂Ｏ、加熱温度１７０℃でカレンダー処理を行い、得られた布帛の断面および表面を電子顕微鏡にて観察した。このようにして得られた布帛を構成する複合繊維の断面は偏平に変形しており、布帛の空隙が詰まったものとなり、表面平滑性に優れている。さらに平面写真から、複合繊維の芯鞘構造は保持されており、芯成分は外に露出しておらず、複合繊維同士の融着は発生していない。このため、耐水性を有しながら布帛の風合いが損なわれることがない。また低温でのカレンダー加工が可能であるため、熱処理によってウレタン弾性糸の物性が損なわれることもない。また上記実施例３〜５により得られた布帛の耐水性はいずれも３０．０ｃｍ以上であり、良好な耐水性を示す。
【００４６】
（３）プリーツ加工織物の説明
非晶質逆転芯鞘型複合繊維の形態安定性を用いたプリーツ加工織物について説明する。
【００４７】
非晶質逆転芯鞘型複合繊維は、織布を構成する経糸群及び／又は緯糸群の全部、又はその一部に使用する。その使用比率が比較的低いのは、経糸群又は緯糸群のみに使用した場合であるが、かかる場合でも、その２５％（重量比）に使用する。これが２５％未満となると形態安定性の乏しいものとなり本発明の目的を達成することはできない。経糸群又は緯糸群上の配置状態は当然均等にし、本質的に交織が好ましい。
【００４８】
しかして、プリーツ線が平行又は略平行なプリーツ形状としては、シーガレット・プリーツ、カートリッジ・プリーツ、ハリケーン・プリーツが挙げられる。又プリーツ線が部分的には平行ではないが全体的には平行とみなされるものとして、マジョリカ・プリーツ、イレギュラー・プリーツが挙げられる。いずれの形状であっても形成されるひだの軸線又は折り目線を基準として、これらの線が織成された経糸群と略平行な生地にあっては、その緯糸群中に占める非晶質逆転芯鞘型複合繊維の糸量（重量比）を、経糸群中の非晶質逆転芯鞘型複合繊維の糸量（重量比）と比較して、少なくともこれと均等、好ましくは多くすることが肝要である。
【００４９】
又、ひだの軸線又は折り目線を基準として、これらの線が織成された緯糸群と略平行な生地にあっては、その経糸群中に占める非晶質逆転芯鞘型複合繊維の糸量（重量比）を、緯糸群中の非晶質逆転芯鞘型複合繊維の糸量（重量比）と比較して、少なくともこれと均等、好ましくは多くすることが肝要である。
【００５０】
本発明はこのように、非晶質逆転芯鞘型複合繊維（単糸）の特性を巧みに利用し、これをプリーツ線に合わせて経又は緯糸群に重点配置することにより、織布中に形成されたプリーツの保持度合を高めるのである。
【００５１】
尚、経緯糸群中の特定フィラメント糸量を略均等に配置したものは、プリーツ線を経緯いずれの方向に向けても良好な耐久性が得られるが、先に説明した通り、プリーツ線に合わせて特定フィラメント糸を重点配置することが好ましい。
【００５２】
又、非晶質逆転芯鞘型複合繊維からなるモノ又はマルチフィラメント糸と交織するフィラメント糸としては、生地として通常使用されるポリアミドフィラメント、ポリエステルフィラメントのモノ又はマルチフィラメント糸及びその加工糸が挙げられる。
【００５３】
〔実施例６〕
イソフタル酸（ＩＰＡ）が酸成分の２５モル％を占め、窒素雰囲気下、１０℃／分の昇温速度で加熱する示差熱分析法（ＤＳＣ法）で融点ピークを生じない実質的に非晶質の軟化点１５０℃の共重合ポリエチレンテレフタレートを芯とし、酸性分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘とする芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、本発明に言う特定フィラメントの糸５０ｄ／１２ｆを製造した。
【００５４】
前記特定フィラメントの糸５０ｄ／１２ｆ（ａ６）と、レギュラーポリエステルの糸５０ｄ／１２ｆ（ｂ６）を緯糸に使用し、緯糸中のＡ糸とＢ糸の混用率を、下記の通り、種々変える一方、レギュラーポリエステルの糸５０ｄ／１２ｆ（ｃ６）を経糸に用い、経１１３本／インチ、緯１０３本／インチのタフタを織成し、下記７種の織物を製造した。
【００５５】
織物番号 項目 緯糸内容 経糸内容

【００５６】
前記各織物に同一の染色と帯電防止処理を行なった後、クリスタルマシンによるプリーツ加工を行ない、更に、乾熱処理後、湿熱によるスチームセットの実施、未実施の二種に分け、次に記載する耐久度試験を実施した。その結果を表５に示す。
【００５７】
【表５】

【００５８】
表５においてセットの有無とは、前述のスチームセットの有無を示す。又浸漬法とは、プリーツ加工した織物を熱水に浸した後、折り目の残存角度を目で測定する方法であり、具体的には、ひだの付いた布又は製品を０．２％の非イオン系浸透剤を含む７０℃の熱水中に３０分間浸漬した後、風乾又は乾燥機で乾燥させ、次いで、乾燥後プレス機の上に折り目を開いた状態にしておき、３０秒間スチーミングを実施し、その後浸漬前のひだの状態と比較するか、「クリーズマスター」とよばれる残存折り目測定器を使って判定するもので、本実施例では前者を用いた。等級は、５級……浸漬前後の折り目が全く同一である。４級……浸漬前より折り目の山が低くなっている。３級……折り目の山が消え、線のみが残っている。２級……わずかに折り目の線が残っている。１級……折り目が全く消失。以上であり、通常業界では３〜４級ならば合格としている。
尚、前記浸漬法の欄において、％は織物を水平状態に置いた場合の伸び率を示すもので、マイナスは測定前より縮んだ状態である。
【００５９】
上記実施例に示す通り、本発明にかかる織物によれば、織地の備える特性により同一のプリーツ加工を受けながら、等級において、その形態保持性を１〜２級向上せしめることが可能となる。
【００６０】
（４）造花の説明
非晶質逆転芯鞘型複合繊維を用いた造花について説明する。
【００６１】
本発明において、造花の素材布地に使用する非晶質逆転芯鞘型複合繊維の芯成分は、前述の如き共重合ポリエステルの他にオレフィン系ポリマーが好ましく、例えば、ポリエチレン、ポリプロピレンまたはエチレンとプロピレンの共重合体であることが好ましい。
【００６２】
非晶質逆転芯鞘型複合繊維の鞘成分には、ポリエチレンテレフタレート、６−ナイロンまたは６，６−ナイロンであるのが好ましいが、これらに限定する必要はなく、他のポリエステル系またはポリアミド系の成分であれば使用可能である。
【００６３】
造花の布地素材としては、以上で説明した非晶質逆転芯鞘型複合繊維を、少なくとも１０容量％使用した布地を素材とするのが好ましい。使用量が１０容量％未満では、形態安定性が得られ難く好ましくない。また混合使用する他の成分としては、軟化点が２２０℃以上のポリエステル系またはナイロン系のものが好ましい。
【００６４】
本発明の造花の製法の１例を示せば、例えば、上記の布地を素材とし、メラミン樹脂コーティングは行わず、通常の精練工程を経たのち、プリント、型抜きおよび形付け熱プレスして、目標の造花を得ることができる。しかし以上の方法に限定する必要はない。
【００６５】
以上のように、本発明の造花においては、非晶質逆転芯鞘型複合繊維を少なくとも１０容量％使用しているため、良好な形態安定性が容易に得られる。また素材の肉厚や手で触ったときの微妙な硬さなどは、原糸の太さ、フィラメント数、芯鞘の容積比率、非晶質逆転芯鞘型複合繊維の使用割合、などにより十分調節が可能である。さらには、メラミン樹脂のコーティングを必要としないので、熱プレスによる素材の融着や異臭発生等の問題が生じず、工程がより短縮できる。
【００６６】
〔実施例７〕
以下、本発明の実施例について具体的に説明する。下記の３種類の原糸を準備した。
原糸（ａ７）：イソフタル酸が酸成分の２５モル％を占め、ＤＳＣ法による測定で、実質的に融点ピークを有しない、軟化点約１５０℃の共重合ポリエチレンテレフタレートを芯成分とし、酸成分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘成分とする芯鞘型複合繊維を、芯鞘比率（容積比）１：１で紡糸し、５０ｄ／１２ｆの糸とした。
原糸（ｂ７）：酸成分がテレフタル酸１００％であるレギュラーポリエステルの５０ｄ／１２ｆの糸。
原糸（ｃ７）：原糸（Ｂ７）と同一。
【００６７】
これらの原糸（ａ７、ｂ７、ｃ７）を緯糸とし、酸成分がテレフタル酸１００％であるレギュラーポリエステルの５０ｄ／４８ｆの糸を経糸としてそれぞれ使用し、加工揚がりの経緯糸密度がインチ当たり１７５本１０５本となるように平織り物（Ａ７、Ｂ７、Ｃ７）を製織し、これらの布地を通常のポリエステル平織り物の加工と同様な工程及び条件で精練した。平織物（Ａ７）は、非晶質逆転芯鞘型複合繊維に該当する原糸（ａ７）を緯糸とした本発明の例である。平織物（Ｂ７、Ｃ７）は、ともに非晶質逆転芯鞘型複合繊維を使用しない同一内容の比較試料であるが、この段階で平織物（Ｃ７）のみにメラミン樹脂加工を施した。つづいて、ごく薄いふじ色に染色しプリントして部分的な色付けを加え、ランの主花びらの形に各１０枚を型抜きした。メラミン樹脂加工を施した（Ｃ７）のみにシリコン油の離型剤を吹き付けたのち、さらに２０５℃にてそれぞれ１０枚を重ね、型枠プレスで花びらに凹凸やそりの形付けをし、最後にフッ素系撥水剤で撥水加工を施して、３種類各１０枚のランの造花主花びら（Ａｆ７、Ｂｆ７、Ｃｆ７）を得た。
【００６８】
本発明の製法により作成された造花（Ａｆ７）は、ハリやコシがあり形態安定性に優れ、手触りが柔らかく、一見したところでは天然の花びらと変わらなかった。しかし一方造花（Ｂｆ７）は、ハリやコシが不十分であり、形態の保持性にも不安があり、また造花（Ｃｆ７）は、熱プレス後花びら同志がくっつきがちであり、異臭の点でも課題を残している。
【００６９】
（５）かつらの説明
非晶質逆転芯鞘型複合繊維をかつらに用いた例について説明する。
かかるかつらは、頭皮を覆うことができるベースネットと、このベースネットに外方へ突出するように植設された多数の人工毛髪と、前記ベースネットの内側に一体的に取り付けられた塗膜体とから成るかつらにおいて、少なくとも前記人工毛髪には、非晶質逆転芯鞘型複合繊維を使用していることを特徴としているものである。
【００７０】
本発明のかつらにおいては、少なくとも人工毛髪は非晶質逆転芯鞘型複合繊維から形成され、ベースネットはレギュラーフィラメント糸から形成される。ベースネットには多数の人工毛髪が手で植設されると共に、塗膜体がベースネットの内側に適宜に縫着される。
【００７１】
ベースネットを形成するフィラメント糸のレギュラーフィラメントの成分は、非晶質逆転芯鞘型複合繊維の鞘成分を構成するポリマーであるのが好ましく、この成分を紡糸してレギュラーフィラメントを得る。
【００７２】
本発明では人工毛髪に非晶質逆転芯鞘型複合繊維を使用することによって、人工毛髪は芯成分の軟化点よりも高く鞘成分の軟化点よりも低い温度で熱セットすることにより、容易に形態を付与することができ、その形態を安定に保持することができる。また、その形態は熱セットにより繰り返し変更することも可能である。尚、複合マルチフィラメント糸をベースネットに使用することは可能ではあるが、特にメリットはなく、通常は行わない。
【００７３】
〔実施例８〕
以下、図面に表された本発明の実施例について具体的に説明する。図１〜図４は本発明のかつらＸの１実施例である。
【００７４】
１は、頭皮を覆うことができるベースネットで、このベースネット１は、環状の布に縫着された周端縁部１ａとこの周端縁部１ａから頭皮を覆うことができるようにキャップ状に編成された植毛用編成部１ｂとから成る。
【００７５】
本実施例において、ベースネットの形成に使用したフィラメント糸のレギュラーフィラメントの成分であるｂポリマーは、酸成分がテレフタル酸１００％あるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）であり、これを紡糸したレギュラーフィラメントを用いて４８０ｄ／１２ｆの原糸とし、これをカセ取りしたのち染色し、さらに編み上げてベースネット１を得た。
【００７６】
２は、ベースネット１の植毛用編成部１ｂに外方へ突出するように植設された多数の人工毛髪２である。本実施例において、人工毛髪２の形成に使用したフィラメント糸の複合フィラメントの成分は、芯成分がａポリマー、鞘成分がｂポリマーである。
【００７７】
さらに具体的には、まず実施例８においてはａポリマーとして、イソフタル酸が酸成分の２５モル％を占め、ＤＳＣ法による測定で、実質的に融点ピークを有しない、軟化点約１５０℃の共重合ポリエチレンテレフタレートを芯成分とし、ｂポリマーとして、前記レギュラーフィラメントに用いたポリエチレンテレフタレートを鞘成分として、太さの異なる２種類の芯鞘型複合フィラメントを、いずれも芯／鞘容積比率１／１で紡糸し、これを用いて８８０ｄ／１６ｆ、および５６０ｄ／１２ｆの糸としカセ染めした。これら２種類の糸をそれぞれ用いて２種類の人工毛髪２（Ａ８，Ｂ８）を得た。
【００７８】
次の実施例においてはａポリマーとして、軟化点約１５５℃のポリプロピレンを芯成分とし、ｂポリマーは、軟化点約２３０℃の６−ナイロンにカーボンブラック、弁柄およびチタンイエローの顔料を混合した着色物を鞘成分として、太さの異なる２種類の芯鞘型複合フィラメントを、いずれも芯／鞘容積比率１／２で紡糸し、これを用いて７２０ｄ／１６ｆ、および６００ｄ／１２ｆの糸とした。これら２種類の糸をそれぞれ用いて２種類の人工毛髪２（Ｃ８，Ｄ８）を得た。
【００７９】
３は、ベースネット１の植毛用編成部１ｂの内側に一体的に取り付けられた塗膜体で、この塗膜体３は合成樹脂材と天然ゴム、合成ゴム等のゴム材とを素材としており、これら素材を溶剤に溶解して液状の塗料とし、これを所望する金型に流し込み、テープ状の塗膜体３を得た。
【００８０】
前記で得たベースネット１および塗膜体３を実施例１および２共に適用し、前記実施例１の２種類の人工毛髪２（Ａ８，Ｂ８）および実施例２の２種類の人工毛髪２（Ｃ８，Ｄ８）をそれぞれ使用して、本発明による４種類のかつら（Ａ８，Ｂ８，Ｃ８，Ｄ８）を得た。
【００８１】
これら本発明によるかつら（Ａ８，Ｂ８，Ｃ８，Ｄ８）と、比較試料として特開平６−１７３１０６号公報に開示された方法により製造されたかつらとを、髪型セット（表面温度１５０℃のホットカーラーによる）の容易性、髪型の持続性および髪型セットの繰り返し性について比較テストを行った結果、いずれのテストにおいても本発明によるかつらが明らかに優れていた。
【００８２】
さらに、前記かつら（ロ）を使用して、髪型セット温度とセット効果との関係を以下の方法（１）〜（４）でテストし評価した。
（１）、カーラーの表面温度を８３℃として毛髪を巻き付け３０分放置、（×）（２）、カーラーに毛髪を巻き付けた状態で１０分間１２０℃のオーブン中にて加温、（○）
（３）、ヘアドライヤーの吹き出し口から５ｃｍ（１２０〜１５０℃）で毛髪をセットする、（○）
（４）、市販のホットカーラーにて５秒間毛髪をセットする、（○）
なお評価方法としては、セット後の状態を目視判定し、さらに実際に着用した実感から、満足を（○）、不満足を（×）とした。以上の結果から、良好なセット性を得るには１２０℃以上でセットするのが好ましい。
【００８３】
上記以外の実施例として、前記のベースネット１、人工毛髪２および塗膜体３には、それぞれゼオライト微粉末や無機系微粉末などの抗菌性微粉末４を混合することができる。その時抗菌性微粉末４はベースネット１、人工毛髪２および塗膜体３にそれぞれ内包されると同時に、あるものは図３および図４で示すように、ベースネット、人工毛髪および塗膜体の外表面に露出する。
【００８４】
さらに別の実施例として、前記人工毛髪２に、深色性、耐候性を発揮させるために、炭化ジルコニウムとこれに亜鉛、銀、銅のいずれか一種または複数の物質を混在させることができる。
【００８５】
（６）外側に非晶質逆転芯鞘型複合繊維を用いた複合糸条の説明
非晶質逆転芯鞘型複合繊維を用いた異収縮混繊糸、抱合性嵩高糸、スラブヤーン（これらを以下、複合糸条という）について説明する。
【００８６】
かかる複合糸条は、沸水収縮率又は残留伸度の異なる高低二種のマルチフィラメントからなる糸条であって、混繊後の収縮処理により、当然、糸条の外側に低収縮率側のマルチフィラメントが位置する。又スラブヤーン、スパンデックスはいずれも巻着糸側が糸条の外側を形成する。
【００８７】
かかる複合糸条においては、処理後、糸条の外側に位置するマルチフィラメントに、予め非晶質逆転芯鞘型複合繊維を使用することにより、糸条全体に防水性、形態安定性を付与する。
【００８８】
しかして、対象とする糸条が、異収縮混繊糸、抱合性嵩高糸、スラブヤーンのいずれであっても、非晶質逆転芯鞘型複合繊維と組み合わす熱可塑性合成繊維のマルチフィラメントとしては、繊維形成能を有するレギュラータイプのポリアミド、ポリエステル、ポリオレフィン等が挙げられる。
【００８９】
重ねて、各糸条の構成を具体的に説明すると、異収縮混繊糸の場合、非晶質逆転芯鞘型複合繊維は、沸水収縮率が８％前後である低沸水収縮率側のマルチフィラメントとして使用する。又レギュラータイプのマルチフィラメントは沸水収縮率２０％前後の高沸水収縮率側のマルチフィラメントとして使用する。両者を流体交絡する過程としては、紡糸−延伸の過程を順次経由した仮撚過程、或は直接紡糸延伸過程のいずれであってもよい。
【００９０】
かかる異収縮混繊糸では、編織形成後の沸水収縮処理等により、低沸水収縮率側の繊維（非晶質逆転芯鞘型複合繊維）は糸条の外側を形成する。
【００９１】
次いでこれが加圧下に熱セットされることにより前述の如く低収縮成分（非晶質逆転芯鞘型複合繊維側）が形態安定性を備えることとなり、嵩高な形状が安定して保持される。
【００９２】
同様に、抱合性嵩高糸にあっては、前記非晶質逆転芯鞘型複合繊維は高伸度加工糸として使用する。他の構成糸は低伸度加工糸として使用する。両者の伸度差は５０％以上である。これにより、最終製品に形成した際、複合糸条の外側に位置する非晶質逆転芯鞘型複合繊維が形態安定性を持ち、尚且、ふくらみを持つため、布帛全体として嵩高な形状を安定して保持し、へたりの少ないものとなる。
【００９３】
又、スラブヤーンにおいては、鞘糸に非晶質逆転芯鞘型複合繊維を使用し、芯糸にレギュラータイプのマルチフィラメントを使用することにより、鞘糸で形成される一重及び多重スパイラル部の形態安全性が優れたものとなり、スラブ部分が安定して固着され、ばらけることがない。
【００９４】
かかる複合糸条においては、異収縮混繊糸、抱合性嵩高糸、スラブヤーン、その他、スパンデックス、カバリングヤーン等、複数種の熱可塑性合成繊維のモノフィラメント又はマルチフィラメントの組み合わせからなる複合糸条において、前述の如く該糸条の外側に位置するマルチフィラメントに、非晶質逆転芯鞘型複合繊維を使用することにより、前記複合糸条によって得られる編・織物・糸等の繊維構造物に高い形態安定性と耐水性を付与するのである。
【００９５】
〔実施例９〕

【０１１０】

【０１１１】
（７）内側に非晶質逆転芯鞘型複合繊維を用いた複合糸条の説明
内側に非晶質逆転芯鞘型複合繊維を用いた複合糸条、具体的には異収縮混繊糸、嵩高性加工糸、スラブヤーン、リング糸、モール糸、その他の意匠糸などについて説明する。
【０１１２】
非晶質逆転芯鞘型複合繊維と組み合わせる他の繊維は、ポリエステル、ポリアミド、ポリオレフィン等の熱可塑性合成繊維、綿、絹、羊毛等の天然繊維、及びレーヨン、アセテートなどの人造繊維よりなる群より選ばれた少なくとも一種の繊維である。
【０１１３】
複合糸条が異収縮混繊糸である場合、ポリエステル、ポリアミド、ポリオレフィン等の熱可塑性合成繊維、綿、絹、羊毛等の天然繊維、及びレーヨン、アセテート等の人造繊維よりなる群から選ばれた２種以上の沸水収縮率の異なる糸条であって、混繊後の収縮処理により、糸条の内側に高収縮率糸が位置する。したがって高収縮率側の糸として非晶質逆転芯鞘型複合繊維を使用する。さらに嵩高性加工糸とはポリエステル、ポリアミド、ポリオレフィン等の熱可塑性合成繊維、綿、絹、羊毛等の天然繊維、及びレーヨン、アセテート等の人造繊維よりなる群から選ばれた伸度差を有する２種以上の糸からなり、合糸後の仮撚加工により低伸度加工糸が糸条の内側に位置する。よって低伸度加工糸として非晶質逆転芯鞘型複合繊維を使用する。又スラブヤーンは当然、芯糸が糸条の内側を形成するから、芯糸に非晶質逆転芯鞘型複合繊維を使用する。
【０１１４】
すなわち本複合糸条においては、複合糸条の内側に位置する糸として、非晶質逆転芯鞘型複合繊維を使用することにより、高度の形態安定性を付与するものである。
【０１１５】
重ねて、各複合糸条の構成を更に具体的に説明すると、まず異収縮混繊糸の場合、前記非晶質逆転芯鞘型複合繊維は沸水収縮率が１０〜３０％である高沸水収縮率側の糸として使用する。又他の構成糸は沸水収縮率が０〜１５％の低沸水収縮率糸として使用し、かつ非晶質逆転芯鞘型複合繊維と他の構成糸の収縮率差が５％以上、好ましくは１０％以上となるように選定する。流体交絡する過程としては、紡糸工程中、延伸工程中、又その後の混繊工程中、或は直接紡糸延伸工程中のいずれであってもよい。
【０１１６】
かかる異収縮混繊糸では、編織形成後の沸水収縮処理等により、高沸水収縮率側の繊維（非晶質逆転芯鞘型複合繊維）は主に糸条の内側に位置する。次いでこれが熱セットされることにより前述の如く高収縮成分（非晶質逆転芯鞘型複合繊維側）が形態安定性を備えることとなる。よって、形態安定性を保持しつつ、低収縮率側の繊維の持つふくらみ等の性質を損なうことがない。
【０１１７】
次に嵩高加工糸にあっては、前記非晶質逆転芯鞘型複合繊維は低伸度加工糸として使用する。他の構成糸は高伸度加工糸として使用する。両者の伸度差は５０％以上である。これにより、最終製品に形成した際、複合糸条の内側に位置する非晶質逆転芯鞘型複合繊維が形態安定性を持ち、尚且、外側に位置する他の構成糸がふくらみを持つため、複合糸条全体としては嵩高な形状を有し、風合いに優れるものとなる。
【０１１８】
又、スラブヤーンにおいては、芯糸に非晶質逆転芯鞘型複合繊維を使用し、鞘糸に他の構成糸を使用することにより、布帛全体として形態安定性の優れたものとなり、なおかつスラブヤーンが本来有している外観品位及び風合いを失うこともない。
【０１１９】
本発明における複合糸条を用いて形態安定性を発揮させるためには該複合糸条を布帛全体の少なくとも３０％以上より好ましくは５０％以上使用することが好ましい。又、織物の経又は緯方向にプリーツ、折目加工を施す場合は、プリーツ線と直行する糸の少なくとも２５％以上、好ましくは３０％以上、更に好ましくは４０％以上を使用することが望ましい。
【０１２０】
〔実施例１３〕
イソフタル酸が酸成分の２５モル％を占め、ＤＳＣ法による測定で実質的に融点ピークを有しない軟化点約１５０℃の共重合ポリエチレンテレフタレートを芯成分とし、酸成分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘成分とする芯鞘比率（容積比）１：１、５０ｄ／２４ｆで沸水収縮率２１．０％である芯鞘型複合フィラメントと極限粘度０．６４のポリエチレンテレフタレートからなる５０ｄ／４８ｆ、沸水収縮率８．０％である（延伸）低収縮フィラメントとを延伸後に合糸し、同時にインターレースノズルに挿通し、両糸条に流体交絡を施して混繊しボビンに巻き取った。この混繊糸を緯糸とし、酸成分がテレフタル酸１００％であるレギュラーポリエステルの５０ｄ／４８ｆ原糸を経糸として経／緯密度が１１０本／ｉｎ×８０本／ｉｎの平織物を製織し、実施例１３の織物を得た。

【０１３２】
【表１０】

【０１３３】
（８）エンボス織物の説明
逆転芯鞘型複合繊維を用いた織物に対するエンボス加工について説明する。
【０１３４】
構成単糸を非晶質逆転芯該鞘型複合繊維により構成したマルチフィラメントは、経糸及び／又は緯糸用としてその一部又は全部に使用する。その使用比率が最も低いのは、経糸又は緯糸のみに使用した場合であるが、かかる場合でも、少なくともその３０％に使用する。これが３０％未満となると、防水性と形態安定性の乏しいものとなり、本発明の目的を達成することはできない。経糸又は緯糸上の配置状態は当然均等にし、本質的に交織が好ましい。また、非晶質逆転芯鞘型複合繊維と交織するマルチフィラメントとしては、通常使用されているレギュラータイプのポリアミドフィラメント及びポリエステルフィラメントのマルチフィラメント並びにその加工糸が挙げられる。
【０１３５】
かかる織物において、経糸方向及び緯糸方向の織物カバーファクター［繊度（デニール）^0.5×打ち込み本数（本／インチ］の和をＴＣＦとすると、このＴＣＦの範囲を８００＞ＴＣＦ＞２５００、にすることが必要である。ＴＣＦが２５００以上になると鮮明な柄の現出、特に形際の明瞭化が困難となり、又８００以下になると耐久性のある織物の製織は困難となる。
【０１３６】
非晶質逆転芯鞘型複合繊維を用いた織物は、織成後、通常のエンボス過程前の前処理である精練過程、液流を使用するリラックス過程、必要に応じて実施する染色過程、及び仕上過程等を順次経由した後、エンボスカレンダー加工機に送られる。
【０１３７】
通常のエンボスカレンダー加工機においては、凸状模様の彫刻を有する硬質加熱ロールとこれと対をなす凹側の軟質ロールの両者を、適当な圧力で圧着させながら回転させ、両ロール間に型押し対象の織物を導入することによりこれへエンボス模様を形成している。そして前記凸部と凹部の高低差は１ｍｍ以上を必要としており、１ｍｍ未満では十分な凹凸模様を形成することは難しいとされている。
【０１３８】
本発明による織物は、図柄作成を加熱下の加圧による織地の凹凸に依存するのではなく、低軟化点且非晶質のポリマーからなる芯成分又は鞘成分を、エンボス加工機の硬質加熱ロールにより押圧させ、そのフィラメント径を変形・増大せしめることで加熱ロールに画かれた凸状模様を織地上に形成する。
【０１３９】
前記エンボス加工過程における織地の変形状態から、本発明織物を製造する装置においては、柄形成用の凸部と凹部の高低差をそれほど必要としない。このため、凸状模様を有する硬質加熱ロールと平滑面を有する軟質ロールの組み合わせでも容易に柄形成を実施し得る。通常、エンボスロール対の加圧力は１０ｋｇ／ｃｍ²程度必要とされるが、本発明にかかる織物では５ｋｇ／ｃｍ²程度で実施することが可能である。
【０１４０】
本発明の織物を得るために重要な加工条件の一つは柄模様を有する硬質加熱ロールの表面温度である。
【０１４１】
非晶質逆転芯鞘型複合繊維の鞘成分として、レギュラーポリエステル繊維又はレギュラーポリアミド繊維を用いた場合は表面温度を１６０〜１９０℃の範囲にするのが適切であり、接圧時間は１秒以上であれば、鮮明で且耐久性に優れたエンボス加工織物を製造し得る。
【０１４２】
〔実施例１６〕
下記の３種の原糸を準備した。
原糸ａ１６−イソフタル酸（ＩＰＡ）が酸性分の２５モル％を占め、ＤＳＣ法による測定で、実質的に融点ピークを有しない、軟化点約１５０℃の共重合ポリエチレンテレフタレートを芯とし、酸性分がテレフタル酸１００％であるポリエチレンテレフタレート（融点２５５℃、軟化点２４０℃）を鞘とする芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、７５ｄ／２４ｆの糸とした。
原糸ｃ１６−酸性分がテレフタル酸１００％であるレギュラーポリエステルの７５ｄ／２４ｆの糸。
【０１４３】
これら２種の原糸に対して夫々、１０００Ｔ／Ｍの追撚を施して試験用緯糸とした。一方酸成分がテレフタル酸１００％であるレギュラーポリエステル７５ｄ／３６ｆの糸に、１０００Ｔ／Ｍの追撚を施して共通して使用する試験用経糸とした。
【０１４４】
このようにして得た経緯糸を夫々、ＷＪＬ織機により、経密度７１本／インチ、緯密度７５本／インチの平織に製織し、試験反Ａ，Ｃとなし、この試験反に夫々、精練、液流によるリラックス、１９０℃の予備セット、１３０℃の染色、１６０℃の仕上セットを施してエンボス加工用原布Ａ１６・Ｃ１６とした。
【０１４５】
これら２反の原布Ａ１６・Ｃ１６を夫々エンボス加工機に仕掛け、所定の花柄模様を施した加熱ロール（１７０℃）と平坦面を有する軟質ゴムロール（常温）間に通して完成されたエンボス加工織物を得た。両ロールの接圧は５ｋｇ／ｃｍ²、接触時間は１秒である。以上三種の加工織物のエンボス加工直後及び洗濯１０回後の形態安定性の試験結果を表１１に示す。尚、形態安定性は直径１０ｍｍのガラス管に試験織物を巻きつけ、熱セットし、冷却し、広げた状態で１００ｇ／ｃｍ²の荷重を載せ、５分後、荷重を取り除いた時の巻き状態と花柄の残留状態を目視判断した。
【０１４６】
【表１１】

【０１４７】
本発明において、経糸方向の織物カバーファクターとは、経糸密度（本／インチ）×（経糸デニール）^0.5の平方根を示し、又緯糸方向の織物カバーファクターとは、緯糸密度（本／インチ）×緯糸デニールの平方根を示す。本発明において定義するＴＣＦとは、前記両者の和である。
【０１４８】
（９）耐水性布帛の説明
芯成分の融点が鞘成分の融点より低い逆転芯鞘型複合繊維は、これを使用した布帛に、カレンダー加工等の加圧熱処理を施すことによって優れた耐水性を得ることができ、傘地用生地や袋物用生地に用いると好適である。以下、かかる耐水性布帛について説明する。
【０１４９】
かかる発明においては、高圧下の熱セットにより水不透性とするものであるから、モノフィラメントは織糸に適さない。袋物用生地としては、総デニールが１００デニール以上、好ましくは２００〜５００デニールのマルチフィラメントであることを要す。総デニールが１００デニール未満であると、袋物用生地としての物性が不十分となる。
【０１５０】
又単糸デニールは通常４〜１５デニール程度が好ましく、単糸強力は２ｇ／ｄ以上であることを要する。
【０１５１】
又、傘地用生地としては、総デニールが３００デニール以下、好ましくは３０〜１５０デニールのマルチフィラメントであることを要す。総デニールが３００デニールを超えると傘地用生地として細密さに欠け、一方３０デニールより細くなると、強度不足と過剰な柔軟さにより取扱いが困難となる。
【０１５２】
又、単糸デニールは通常１〜８デニールが好ましく、単糸強力は２ｇ／ｄ以上であることを要する。
【０１５３】
構成単糸を逆転芯鞘型複合繊維により構成した前記マルチフィラメントは経糸及び／又は緯糸用としてその一部、又は全部に使用する。その使用比率が最も低いのは、経糸又は緯糸のみに使用した場合であるが、かかる場合でも、少なくともその２０％に使用する。これが２０％未満となると、防水性と形態安定性の乏しいものとなり、本発明の目的を達成することはできない。経糸又は緯糸上の配置状態は当然均等にし、本質的に交織が好ましい。
【０１５４】
逆転芯鞘型複合繊維と交織するマルチフィラメントとしては、生地として通常使用されるポリアミドフィラメント、ポリエステルフィラメントのマルチフィラメント及びその加工糸が挙げられる。
【０１５５】
耐水性織物はこのような糸条を経糸及び／又は緯糸に用いて織成するが、十分な防水性を得るには、織成に際して密度を高めにすることが必要である。経糸方向及び緯糸方向の織物カバーファクター［（繊度（デニール））^0.5×打ち込み本数（本／インチ）］の和をＴＣＦとすると、３５００＞ＴＣＦ＞８００の範囲、好ましくは、３５００＞ＴＣＦ＞１２００の範囲にある高密度にすることが重要である。ＴＣＦが８００未満になると、カレンダー加工等を使用した加圧下での熱セットにより織組織の間隙を十分に詰めることができず、又、３５００以上では製織性に難点がある。使用される織物の組織は、平織及びその変化織、綾織及びその変化織、朱子織及びその変化織が好ましい。
【０１５６】
又、本発明にかかる生地は、本質的には撥水加工及び防水加工が不必要であり、その点に重要な特徴があるが、必要に応じてこれらの処理を公知の方法で行うことが出来る。例えば、アクリル系、シリコン系或はフッ素系の撥水剤をスプレー法、バッチング法、浸漬法、コーティング法等の方法で付与し得る。
【０１５７】
また、かかる耐水性布帛に用いる逆転芯鞘型複合繊維の芯成分には、前述した、ＪＩＳ Ｋ ７１９６の熱機械分析法で測定した芯成分の軟化点が鞘成分の軟化点より２０℃以上低く、前記芯成分が、窒素雰囲気下、１０℃／分の昇温速度で加熱する示差熱分析法で融点ピークを生じない実質的に非晶質のポリマーを用いることが好ましい。
【０１５８】
〔実施例１７〕
以下、実施例について具体的に説明するが、実施例中の耐水圧はＪＩＳ Ｌ−１０９２Ａ法（静水圧法）によるものであり、又形態安定性は直径１０ｍｍのガラス管に試料を巻きつけ、１６０℃×３分の熱セットをし、冷却し、広げた状態で１００ｇ／ｃｍ²の荷重を載せ、５分後、荷重を取り除いた時の巻き状態を目視判断した。
【０１５９】
袋物用として、下記二種の原糸を準備した。
イソフタル酸（ＩＰＡ）が酸成分の２５モル％を占め、窒素雰囲気下、１０℃／分の昇温速度で加熱する示差熱分析法（ＤＳＣ法）で融点ピークを生じない実質的に非晶質の軟化点１５０℃の共重合ポリエチレンテレフタレートを芯とし、ポリアミドを鞘とする芯鞘型複合繊維を芯鞘比率（容積比）１：１で紡糸し、２１０ｄ／１６ｆの糸を得た。これを原糸ａ１７とした。
一方、通常工程によって得られたレギュラーポリアミドからなる２１０ｄ／１６ｆの糸を原糸ｂ１７とした。
【０１６０】
原糸ａ１７と原糸ｂ１７を夫々経糸及び緯糸に用いて加工揚りの経緯糸密度が６４本／インチ×４６本／インチとなるように平織物を製造し、これらの布帛を夫々ポリエステル平織物、ポリアミド平織物の加工と同様の工程及び条件で染色（液流型染色機）と、加圧下の熱セットを含む仕上加工を行った。
このようにして得た袋物用生地に、原糸ａ１７のものには撥水加工をせず、原糸ｂ１７のものにはフッ素系撥水剤を用いて通常の撥水処理を施した。
【０１６１】
両者の防水性と形態安定性を測定した結果、表１２に示す結果を得た。
【表１２】

【０１６２】
傘地用として下記二種の原糸を準備した。
実施例１７の原糸ａ１７に用いた芯鞘型複合繊維と同様の成分からなる７５ｄ／２４ｆの糸を原糸ｃ１７とする。一方、通常工程によって得られたレギュラーポリエステルからなる７５ｄ／２４ｆの糸を原糸ｄ１４とする。
【０１６３】
原糸ｃ１７と原糸ｄ１７を夫々経糸及び緯糸に用いて加工揚りの経緯糸密度が１００本／インチ×９０本／インチとなるように平織物を形成し、この織物をＡ１７織物とする。一方、原糸ｄ１７を経緯糸の両方に用いて加工揚りの経緯糸密度が１００本／インチ×９０本／インチとなるように平織物を形成し、この織物をＢ１７織物とする。
このようにして得た傘地用生地に、９５℃の精練→１８５℃、２０秒のセット→ビーム染色機を用いた染色→アクリル樹脂による１２０℃のコーティング→フッ素系樹脂による１７０℃の撥水処理を施して完成された二種の傘地を得た。両者の防水性と形態安定性を測定した結果、表１３に示す結果を得た。
【０１６４】

BACKGROUND OF THE INVENTION
The present invention relates to a fabric having shape stability and / or water resistance obtained by heat setting, and a core-sheath type composite fiber used therefor.
[0002]
[Prior art]
Conventionally, a fabric using a composite fiber having a core-sheath cross-sectional shape using a low-melting-point polymer as a sheath component (hereinafter referred to as a normal core-sheath type composite fiber), and the entanglement point of warp and weft by heat treatment The fusion bonded fabric is used for various purposes.
However, such a fabric has a poor texture (hard), and a low melting point polymer component appears on the surface of the fabric, so that the fastness to dyeing is deteriorated or the dyeability is inferior. There are many problems.
On the other hand, only a few examples of the fabric using a core-sheath type composite fiber using a low melting point polymer as a core component (hereinafter referred to as a reverse core-sheath type composite fiber) are recognized. For example, in JP-A-6-220770, an ethylene-vinyl acetate copolymer is used for the core component and a polyamide component is used for the sheath component in order to obtain a fabric having a clear ridge-like unevenness and color difference on the fabric surface. Inverted core-sheath type composite fiber is used, and JP-A-4-11006 discloses a reverse core-sheath type composite in which a low melting point polymer is arranged as a core component for the purpose of developing sports clothing having improved frictional melt resistance. Discloses the use of false twisted yarn made of fiber.
[0003]
The former fabric is bent and heat-fixed. However, if the heat treatment conditions are not strictly controlled, the fiber feels worse or the bending portion is weakly fixed. It was not used for any specific purpose other than the product to which was given. The latter is intended for the development of clothing that does not have holes due to friction caused by sliding, etc., and although it uses a reversed core-sheath type composite fiber that uses a low-melting-point polymer as the core component, The composite fiber does not exhibit any peculiar effect on the formability of the fabric or clothing.
[0004]
On the other hand, in order to obtain a waterproof cloth suitable for form stability such as pleating and hard finishing, and umbrellas, it has been essential to coat the surface of the cloth with a melamine resin, an acrylic resin, or the like.
However, these resin coatings have drawbacks that the texture becomes hard and that some resins may cause problems such as bad odor during thermoforming. In addition, in the coating of acrylic resin or the like, dye migration is likely to occur on the coating surface. For example, an umbrella left in the rear window portion of a passenger car causes a fatal defect as a product, such as dye transfer immediately, and the umbrella becomes uneven in color or the printed pattern becomes unclear.
In addition, as a method for obtaining a water-resistant fabric, it is generally known that heat and pressure treatment such as calendering is performed. However, even if calendering is performed on a fabric using a normal polyester yarn or the like, yarn entanglement is performed. It was difficult to completely fill the gaps between the dots and to obtain dramatic water resistance.
[0005]
[Problems to be solved by the invention]
The present invention provides a fabric using a core-sheath type composite fiber, and provides a fabric having good shape stability and / or high water resistance without using a resin coating or the like, and uses it. An object of the present invention is to provide a novel core-sheath type composite fiber.
[0006]
Further, the present inventors have conceived that a very useful final product can be obtained by applying the shape stability of the core-sheath composite fiber to a specific application.
[0007]
For example, a fabric excellent in surface smoothness can be obtained by subjecting a woven or knitted fabric using a covering yarn composed of the core-sheath type composite fiber and urethane elastic yarn to heat and pressure treatment. Such a fabric is conventionally coated with a urethane resin or the like on the surface of the fabric because the fluid resistance of the wear surface against air or water slows down the speed in swimming, skiing, snowboarding, cycling, speed skating, etc. Or a method of improving smoothness by laminating films.
[0008]
However, since the conventional fabric has a resin layer or a film layer with very few gaps, it has poor moisture permeability and air permeability, and further has a problem of high density and large thickness. For this reason, as a sports material, a material that is light and thin and has moisture permeability and air permeability is preferred, and it is desired to obtain a fabric excellent in smoothness and water resistance without applying a resin coating or a film laminate. It was.
[0009]
Furthermore, a durable embossed pattern can be formed by embossing the woven fabric using the core-sheath type composite fiber or the like. For embossing, generally, a heated hard engraving roll and a soft roll paired therewith are rotated under appropriate pressure conditions, and a fabric is introduced between the two rolls to make it easy to create an uneven pattern. However, the woven fabric using conventional polyester yarns has poor durability, and has the disadvantages that the unevenness can be easily reduced or lost by washing or the like.
In addition, conventionally, fibers have been known in which low melting point components on the surface are fused by heat treatment and exhibit shape stability, etc., but such fibers have the disadvantage that the texture is cured as described above, Its use was also limited.
[0010]
Another object of the present invention is to apply a specific core-sheath-type conjugate fiber to a specific application, thereby producing unique effects based on the shape stability of the core-sheath-type conjugate fiber. The object is to provide a very useful end product that could not be obtained with mold composite fibers.
[0011]
[Means for Solving the Problems]
The present invention relates to a core-sheath type composite fiber composed of different polymers, wherein the softening point of the core component measured by the thermomechanical analysis method of JIS K 7196 is 20 ° C. or more lower than the softening point of the sheath component, and the core component is And consisting of a substantially amorphous polymer that does not produce a melting point peak in a differential thermal analysis method heated at a rate of temperature increase of 10 ° C./min in a nitrogen atmosphere (hereinafter referred to as an amorphous inverted core-sheath type composite fiber) ).
[0012]
The present invention also relates to a fabric, artificial flower, and wig having shape stability using such an amorphous inverted core-sheath composite fiber.
[0013]
Such amorphous inverted core-sheath type composite fibers use a substantially amorphous polymer having a low crystallinity as a core component, and therefore soften reversibly even if heating and cooling are repeated. Solidification can be repeated, and the setability such as flattening of the yarn by heating under pressure is very good.
[0014]
In addition, the present invention relates to an embossed woven fabric obtained by pressing a heated engraving roll on a fabric woven from multifilaments of thermoplastic synthetic fibers. Embossing with excellent morphological stability, characterized by using multifilaments composed of amorphous inverted core-sheath type composite fibers and the sum of the warp and weft cover factors in the range of 800-2500 It is a woven fabric.
[0015]
Such a woven fabric does not depend on the unevenness of the fabric by pressurization under heating, but a sheath component made of an amorphous polymer with a low softening point is pressed by a hard heating roll of an embossing machine, Since a convex pattern drawn on the heating roll is formed on the fabric by deforming and increasing the filament diameter, a durable embossed pattern is obtained.
[0016]
Furthermore, the present invention is a fabric using at least a part of a reversible core-sheath composite fiber in which the melting point of the core component is lower than the melting point of the sheath component, at a temperature above the softening point of the core component and below the melting point of the sheath component, A fabric having water resistance, wherein the fabric is formed into a flat state by heat setting under pressure.
[0017]
Such a fabric has no gap at the intersection of the yarns constituting the fabric, and becomes a fabric having water resistance.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
(1) Description of amorphous inverted core-sheath composite fiber
The amorphous inverted core-sheath type composite fiber of the present invention, that is, the core-sheath type composite fiber having a softening point of the core component measured by a thermomechanical analysis method of JIS K 7196 is 20 ° C. or more lower than the softening point of the sheath component, The composite fiber in which the core component is made of a substantially amorphous polymer that does not generate a melting point peak in a differential thermal analysis method in which the core component is heated at a heating rate of 10 ° C./min in a nitrogen atmosphere is particularly a sheath component. Core-sheath type composite fiber made of a copolyester polymer having a glass transition point of 60 to 80 ° C. and a softening point of 200 ° C. or less is used.
[0019]
Typical examples of such copolymer polyesters include terephthalic acid and ethylene glycol as main components, and as a copolymer component, oxalic acid, malonic acid, succinic acid, adipic acid, azelaic acid, sebacic acid, phthalic acid, One or more of known dicarboxylic acid components such as isophthalic acid, naphthalenedicarboxylic acid, diphenyl ether dicarboxylic acid, etc., and 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, propylene glycol, One or more of known diol components such as trimethylene glycol, tetramethylene glycol, hexamethylene glycol, diethylene glycol, polyalkylene glycol, 1,4-cyclohexanedimethanol, etc. are used, and the ratio is 50 mol% or less Preferably those copolymerized diethylene glycol as other copolymerizable components, polyethylene glycol and the like may be added.
[0020]
Further, the copolymer polyester may be a copolymer component as described above, which is appropriately selected and used within a range of physical properties that do not impair spinning and processing operability so as to have a desired softening point. Those using ethylene glycol as a main component and using isophthalic acid as a copolymerization component are preferable because they are industrially inexpensive and can be stably obtained and have good polymer properties. In such an isophthalic acid copolymer polyester, the isophthalic acid component is preferably 20 to 40 mol%, and the core / sheath ratio of the core-sheath type composite fiber is 5/1 to 1/5 in volume ratio, particularly It is preferably about 3/1 to 1/2. The cross-sectional shape of the composite fiber may be any of a circle, an ellipse, a polygon, a star, etc., and the core and the sheath may be arranged concentrically or eccentrically. It is preferable to use a circular shape having a core and a sheath arranged concentrically, and the core component has a core-sheath structure that is not exposed to the outside.
[0021]
Since such a composite fiber uses a substantially amorphous polymer having a low crystallinity as a core component, it can be reversibly softened and solidified even if heating and cooling are repeated. Also, the setability such as flattening of the yarn by heating under pressure is very good.
[0022]
Therefore, the fabric using such a composite fiber has the following advantages.
(1) The shape once heat-set can be released again by heating and heat-set to a new shape. For example, after manufacturing a pleated curtain with a 5 cm wide crease by heat setting, this pleat is removed by heating and set again on a pleated curtain with a different crease (for example, a crease with a width of 3 cm). , Quality is possible.
{Circle around (2)} Even without resin coating, the product can be made into a water-resistant product that can be used efficiently for umbrellas, waterproof clothing, etc., only by pressure heat setting by ordinary calendering or the like. However, a resin coating can be used in combination depending on the application. {Circle around (3)} The water resistance and shape retention obtained in this way are highly durable for washing. (4) Since the core component of the composite fiber does not appear on the surface of the fabric, the texture does not become hard, and problems such as a decrease in dyeing fastness and a decrease in levelness are unlikely to occur.
[0023]
[Example 1]
The following three types of raw yarns were prepared.
Raw yarn (a1) -isophthalic acid (IPA) occupies 12 mol% of the acid component, the core is copolymerized polyethylene terephthalate having a melting point of 227 ° C. (DSC method) and a softening point of 197 ° C., and the acid component is terephthalic acid A core-sheath type composite fiber having a sheath of 100% polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) was spun at a core-sheath ratio (volume ratio) of 1: 1 to obtain a yarn of 50d / 12f.
Original yarn (b1)-50d / 12f yarn in which the core component and sheath component of the original yarn (a1) are reversed.
Original yarn (c1)-50d / 12f yarn of regular polyester whose acid component is 100% terephthalic acid.
[0024]
These three types of yarns are used as wefts for fabrics made from 50d / 24f yarns of regular polyester whose acid component is 100% terephthalic acid, and the processed weft density is 110 yarns / in × 94 yarns. A plain woven fabric (A1, B1, C1) is woven so as to be / in, and the obtained fabric is dyed (liquid flow type dyeing machine) and finished in the same process and conditions as the processing of a normal polyester plain woven fabric. .
[0025]
At this stage, the fabric (A1) of the present invention and the fabric (C1), which is a normal polyester fabric, were able to obtain a uniform dyed fabric. The weft fabric (B1) had stained spots, wrinkles and poor appearance.
[0026]
Next, the dyed fabric thus obtained was subjected to normal water-repellent processing using a fluorine-based water repellent, and 35 kg / cm ² In the pressurized state, heat treatment (calendar processing) at 200 ° C. was performed, and the water pressure resistance immediately after the processing and 10 times after washing was measured.
The results are shown in Table 1.
[0027]
[Table 1]

[0028]
The fabric (A1) according to the present invention has a soft texture and a high water pressure resistance, and can be used as an umbrella even without a resin coating. On the other hand, the fabric (B1) has a higher water pressure resistance than the normal polyester fabric (C1), but its value is insufficient for use in umbrellas, etc. The remaining texture became stiff and was not practical.
[0029]
[Example 2]
The following three types of raw yarns were prepared.
The raw yarn (a2) -isophthalic acid (IPA) accounts for 25 mol% of the acid component, and has a melting point peak as measured by DSC method, and has a softening point of about 150 ° C. as a core, A core-sheath type composite fiber having a core-sheath ratio (volume ratio) of 1: 1 was spun with polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) having an acid component of 100% terephthalic acid as a sheath. It was a thread.
Original yarn (b2)-50d / 12f yarn in which the core component and sheath component of the original yarn (a2) are reversed.
Raw yarn (c2)-50d / 12f yarn of regular polyester whose acid component is 100% terephthalic acid.
[0030]
These three types of yarns are used for the wefts of fabrics made from 50d / 48f yarns of regular polyester whose acid component is 100% terephthalic acid, and the processed weft density is 175 yarns / in × 105 yarns. Plain fabrics (A2, B2, C2) were woven so as to be / in, and these fabrics were dyed (liquid flow type dyeing machine) and finished in the same process and conditions as those for ordinary polyester plain fabrics. Next, the dyed fabric thus obtained was subjected to normal water repellent treatment using a fluorine-based water repellent.
[0031]
Table 2 shows the results of measuring the form stability of each fabric after the water-repellent processing and the results of measuring the water pressure resistance and the form stability of the fabric subjected to pressure heat treatment at 160 ° C. after the water-repellent processing.

[0033]
(2) Description of urethane covering yarn and surface smooth fabric
The amorphous inverted core-sheath composite fiber can be used together with a urethane elastic body and used for sportswear. In this case, the urethane elastic yarn may be a commonly used one. The urethane resin used for the elastic yarn may be polyester or polyether, but if the heat treatment time in the later process is long and it is necessary to increase the heat resistance, it will be more heat resistant. It is preferable to use an excellent polyester-based polyurethane. The spinning method of the polyurethane fiber is not particularly limited, and usual methods such as melt spinning and dry spinning are preferably used.
[0034]
As a method for making a woven or knitted fabric using these fibers, specifically, a method for producing a covering yarn using a urethane elastic yarn as a core yarn and an amorphous inverted core-sheath type composite fiber as a sheath yarn, and using the same as a woven or knitted fabric , A method of making a woven or knitted fabric using both an amorphous inverted core-sheath type composite fiber and a urethane elastic yarn, and a method of making a woven or knitted fabric as a blended yarn of an amorphous inverted core-sheath type composite fiber and a urethane elastic yarn Etc. can be used.
[0035]
When using a covering yarn having a urethane elastic yarn as a core yarn and an amorphous inverted core-sheath type composite fiber as a sheath yarn, a generally used method can be suitably used as the method for producing the covering yarn. The wrapping of the sheath yarn may be single or double. Further, such a composite mixed yarn may be a woven fabric or a knitted fabric, and the method for producing the woven or knitted fabric is not limited.
[0036]
As a method for producing a woven or knitted fabric using both the amorphous inverted core-sheath composite fiber and the urethane elastic yarn at the same time, a known method can be suitably used, which is desirable from the required form stability and stretchability. Weaving and knitting can be selected. Specifically, normal warp knitting, weft knitting or weaving simultaneously using amorphous inverted core-sheath composite fiber and urethane elastic yarn, warp structure and urethane using amorphous inverted core-sheath composite fiber Examples thereof include a knitted fabric composed of weft structures using elastic yarns.
[0037]
A known method can be used as a method for producing a mixed fiber of amorphous inverted core-sheath composite fiber and urethane elastic yarn. Specific examples include a method in which a urethane elastic yarn is combined with a processed yarn made of a composite fiber, and a method in which a composite fiber and a urethane elastic yarn are combined and then subjected to false twisting to obtain a processed yarn. Further, such a composite mixed yarn may be a woven fabric or a knitted fabric, and the method for producing the woven or knitted fabric is not limited.
[0038]
Furthermore, the fabric having the surface smoothness of the present invention is obtained by subjecting the woven or knitted fabric obtained by the above method to a heat and pressure treatment to smooth the surface. In order to make sportswear with excellent surface smoothness, it is possible to perform such treatment, transform the cross section of the composite fiber into a flat shape, reduce the bulge of the surface of the woven or knitted fabric, and close the gap is necessary. The heat and pressure treatment can be performed by a method usually used, for example, calendar processing.
[0039]
It is preferable that the heating temperature in such a heating and pressurizing treatment is 150 ° C. to 200 ° C., more preferably 160 ° C. to 180 ° C. Amorphous inverted core-sheath composite fiber has a low melting point and low crystallinity at the core, so it is possible to deform the fiber cross-sectional shape at a low temperature, resulting in thermal degradation of the urethane elastic yarn in the heat treatment process. This will be significantly reduced, which is preferable. When heated at a temperature higher than 200 ° C., heat deterioration of the urethane elastic yarn occurs, or the core component is exposed to the outside due to melting of the sheath component of the amorphous inverted core-sheath composite fiber, and the texture of the fabric is impaired. Therefore, it is not preferable. Further, the heat and pressure treatment at a temperature lower than 150 ° C. does not sufficiently deform the yarn shape, and sufficient smoothness cannot be obtained.
[0040]
Example 3
Each physical property value was measured by the following method.
Water pressure resistance: JIS L-1092A method (hydrostatic pressure method)
Softening point: JIS K-7196 method
Production of knitted tricot: Isophthalic acid accounts for 25 mol% of the acid component, has substantially no melting point as measured by DSC method, and has a softening point of 197 ° C as the core, and the acid component is terephthalate The core-sheath type composite fiber is spun at a core-sheath ratio (volume ratio) of 1: 1 using polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.), which is 100% acid, as a yarn of 45 d / 10 f. False twisting was performed to obtain a processed yarn. Using such processed yarn and 40d urethane elastic yarn, a knitted tricot was formed.
[0041]
Example 4
Production of covering yarn: Isophthalic acid occupies 25 mol% of the acid component, has substantially no melting point as measured by DSC method, and has a softening point of 197 ° C as a core, and the acid component is terephthalic acid 100% polyethylene terephthalate (melting point 255 ° C., softening point 240 ° C.) as a sheath, core-sheath type composite fiber is spun at a core-sheath ratio (volume ratio) of 1: 1 to obtain a yarn of 50d / 12f, and interlace After granting, it was scraped off. Next, a single covering yarn was manufactured under the conditions shown in the table below using the 20d urethane elastic yarn as the core yarn and the composite fiber as the sheath yarn.
[0042]
[Table 3]

Using the covering yarn, a tricot knitted fabric was produced according to a conventional method.
[0043]
Example 5
Production method of blended yarn: isophthalic acid accounts for 25 mol% of the acid component, has substantially no melting point as measured by DSC method, and has a softening point of 197 ° C. A core-sheath type composite fiber with a sheath of polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) whose terephthalic acid is 100% is spun at a core-sheath ratio (volume ratio) of 1: 1, did. The above composite fiber and 20d urethane elastic yarn were used as a mixed fiber composite processed yarn under the conditions shown in Table 4.
[0044]
[Table 4]

A tricot knitted fabric was produced according to a conventional method using the above mixed yarn.
[0045]
A pressure of 700 mmH is applied to the stretch knitted fabric manufactured by the methods of Examples 3 to 5 above. ₂ The calendar process was performed at O and the heating temperature of 170 degreeC, and the cross section and surface of the obtained fabric were observed with the electron microscope. The cross-section of the composite fiber constituting the fabric thus obtained is flatly deformed, the gap of the fabric is clogged, and the surface smoothness is excellent. Furthermore, from the planar photograph, the core-sheath structure of the composite fiber is maintained, the core component is not exposed to the outside, and the composite fiber is not fused. For this reason, the texture of the fabric is not impaired while having water resistance. Further, since calendering at a low temperature is possible, the physical properties of the urethane elastic yarn are not impaired by the heat treatment. In addition, the water resistance of the fabrics obtained in Examples 3 to 5 was 30.0 cm or more, indicating good water resistance.
[0046]
(3) Explanation of pleated fabric
The pleated fabric using the shape stability of the amorphous inverted core-sheath composite fiber will be described.
[0047]
The amorphous inverted core-sheath type composite fiber is used for all or part of the warp group and / or the weft group constituting the woven fabric. The use ratio is relatively low when it is used only for the warp group or the weft group, but even in such a case, it is used for 25% (weight ratio). If this is less than 25%, the shape stability becomes poor and the object of the present invention cannot be achieved. Naturally, the arrangement state on the warp group or the weft group is uniform, and union is essentially preferable.
[0048]
Thus, examples of the pleat shape in which the pleat lines are parallel or substantially parallel include a cigarette pleat, a cartridge pleat, and a hurricane pleat. Major pleats and irregular pleats may be considered that the pleat lines are not partially parallel but are considered to be parallel as a whole. With respect to the fold axis or crease line formed in any shape, if the fabric is substantially parallel to the woven warp group, the amorphous reversal in the weft group The yarn amount (weight ratio) of the core-sheath type composite fiber may be at least equal to, and preferably increased, compared with the yarn amount (weight ratio) of the amorphous inverted core-sheath type composite fiber in the warp group. It is essential.
[0049]
In addition, when the fabric is substantially parallel to the weft group in which these lines are woven on the basis of the fold axis line or the crease line, the yarn amount of the amorphous inverted core-sheath conjugate fiber in the warp group It is important to make (weight ratio) at least equal to, and preferably larger than, the yarn amount (weight ratio) of the amorphous inverted core-sheath composite fiber in the weft group.
[0050]
In this way, the present invention skillfully utilizes the characteristics of the amorphous inverted core-sheath type composite fiber (single yarn), and places it in the woven fabric by focusing on the warp or weft group in accordance with the pleat line. This increases the degree of retention of the formed pleats.
[0051]
In addition, when the specific filament yarn amount in the warp and weft group is arranged substantially evenly, good durability can be obtained regardless of the direction of the pleat line, but as explained above, It is preferable to place the specific filament yarn in an important position.
[0052]
In addition, examples of filament yarns that interweave with mono- or multi-filament yarns composed of amorphous inverted core-sheath composite fibers include polyamide filaments, polyester filament mono- or multi-filament yarns that are usually used as fabrics, and processed yarns thereof. .
[0053]
Example 6
Isophthalic acid (IPA) occupies 25 mol% of the acid component and is substantially amorphous with no melting point peak produced by differential thermal analysis (DSC method) in which heating is performed at a heating rate of 10 ° C./min in a nitrogen atmosphere. A core-sheath composite fiber having a core of copolymerized polyethylene terephthalate having a softening point of 150 ° C. and a sheath of polyethylene terephthalate having an acidic content of 100% terephthalic acid (melting point: 255 ° C., softening point: 240 ° C.) Ratio) Spinning was performed at a ratio of 1: 1 to produce a specific filament yarn 50d / 12f according to the present invention.
[0054]
The specific filament yarn 50d / 12f (a6) and regular polyester yarn 50d / 12f (b6) are used as weft yarns, and the mixing ratio of A yarn and B yarn in the weft yarns is variously changed as follows, Regular polyester yarn 50d / 12f (c6) was used as warp, and taffeta of warp 113 / inch and weft 103 / inch was woven to produce the following seven types of fabrics.
[0055]

[0056]
Each fabric is subjected to the same dyeing and antistatic treatment, and then subjected to pleating with a crystal machine. Further, after dry heat treatment, steam set by wet heat is performed, and is divided into two types that have not been performed. Degree test was conducted. The results are shown in Table 5.
[0057]
[Table 5]

[0058]
In Table 5, the presence / absence of a set indicates the presence / absence of the aforementioned steam set. The dipping method is a method in which a pleated fabric is dipped in hot water, and then the remaining angle of the fold is measured with eyes. Immerse in 70 ° C hot water containing an ionic penetrant for 30 minutes, then air dry or dry with a dryer, and after drying, leave the crease open on the press and steam for 30 seconds. This is carried out and then compared with the state of the pleats before immersion, or is determined using a residual crease measuring device called “crease master”. In the present example, the former was used. Grade 5 ... The creases before and after immersion are exactly the same. Grade 4: The crease peak is lower than before immersion. Level 3 ... The crease mountain disappears and only the line remains. 2nd level: A slight crease line remains. 1st grade: The crease disappears completely. That's it, and in the normal industry, grades 3 to 4 are acceptable.
In the column of the dipping method,% indicates the elongation when the woven fabric is placed in a horizontal state, and minus indicates a state in which the fabric is shrunk from before measurement.
[0059]
As shown in the above embodiment, according to the woven fabric according to the present invention, it is possible to improve the form retention of the grade by 1 to 2 while receiving the same pleating due to the characteristics of the fabric.
[0060]
(4) Explanation of artificial flowers
An artificial flower using an amorphous inverted core-sheath composite fiber will be described.
[0061]
In the present invention, the core component of the amorphous inverted core-sheath composite fiber used for the artificial fabric material is preferably an olefin polymer in addition to the copolymer polyester as described above, for example, polyethylene, polypropylene, or ethylene and propylene. A copolymer is preferred.
[0062]
The sheath component of the amorphous inverted core-sheath composite fiber is preferably polyethylene terephthalate, 6-nylon or 6,6-nylon, but is not limited thereto, and other polyester-based or polyamide-based Any component can be used.
[0063]
As the artificial fabric material, it is preferable to use a fabric using at least 10% by volume of the amorphous inverted core-sheath composite fiber described above. If the amount used is less than 10% by volume, it is difficult to obtain form stability, which is not preferable. Further, as other components to be mixed and used, polyester-based or nylon-based ones having a softening point of 220 ° C. or higher are preferable.
[0064]
If an example of the manufacturing method of the artificial flower of the present invention is shown, for example, the above-mentioned fabric is used as a raw material, melamine resin coating is not performed, a normal scouring process is performed, and then printing, die cutting and shaping hot pressing are performed. Can be obtained. However, it is not necessary to limit to the above method.
[0065]
As described above, in the artificial flower of the present invention, since at least 10% by volume of the amorphous inverted core-sheath composite fiber is used, good shape stability can be easily obtained. In addition, the thickness of the material and the subtle hardness when touched by hand are sufficient depending on the thickness of the yarn, the number of filaments, the volume ratio of the core sheath, the usage ratio of the amorphous inverted core-sheath composite fiber, etc. Adjustment is possible. Furthermore, since a melamine resin coating is not required, problems such as material fusion and off-flavor generation by hot pressing do not occur, and the process can be further shortened.
[0066]
Example 7
Examples of the present invention will be specifically described below. The following three types of raw yarns were prepared.
Raw yarn (a7): Isophthalic acid accounts for 25 mol% of the acid component, and has a melting point peak measured by DSC method, and has a softening point of about 150 ° C. as a core component. A core-sheath type composite fiber having a sheath component of polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) whose terephthalic acid is 100% is spun at a core-sheath ratio (volume ratio) of 1: 1, and a yarn of 50d / 12f It was.
Raw yarn (b7): 50d / 12f yarn of regular polyester whose acid component is 100% terephthalic acid.
Original yarn (c7): Same as original yarn (B7).
[0067]
These raw yarns (a7, b7, c7) are used as weft yarns, and 50d / 48f yarns of regular polyester whose acid component is 100% terephthalic acid are used as warp yarns, respectively, and the processed weft yarn density is 175 per inch. Plain weaves (A7, B7, C7) were woven so that there were 105 pieces, and these fabrics were scoured in the same process and conditions as the processing of ordinary polyester plain weaves. The plain woven fabric (A7) is an example of the present invention in which the raw yarn (a7) corresponding to the amorphous inverted core-sheath composite fiber is used as the weft. The plain woven fabrics (B7, C7) are comparative samples having the same contents that do not use the amorphous inverted core-sheath conjugate fiber, but at this stage, only the plain woven fabric (C7) was subjected to melamine resin processing. Subsequently, it was dyed and printed in a very pale Fuji color to add partial coloration, and 10 sheets were cut into the shape of the main petals of the orchid. After spraying the release agent of silicone oil only on the melamine resin processed (C7), layer 10 sheets each at 205 ° C, and shape the petals with unevenness and warp with a mold press, and finally Water-repellent treatment was performed with a fluorine-based water repellent agent, and three kinds of orchid artificial flower petals (Af7, Bf7, Cf7) were obtained.
[0068]
The artificial flower (Af7) produced by the production method of the present invention has elasticity and stiffness, is excellent in shape stability, is soft to the touch, and at first glance is not different from natural petals. However, artificial flowers (Bf7) are insufficient in firmness and stiffness, and there is anxiety about their form retention, and artificial flowers (Cf7) tend to stick together with petals after heat pressing. Is leaving.
[0069]
(5) Explanation of wig
An example in which an amorphous inverted core-sheath composite fiber is used for a wig will be described.
Such a wig includes a base net that can cover the scalp, a number of artificial hairs that are planted so as to protrude outward from the base net, and a coating body that is integrally attached to the inside of the base net. Is characterized in that amorphous synthetic sheath-core composite fibers are used at least for the artificial hair.
[0070]
In the wig of the present invention, at least the artificial hair is formed from an amorphous inverted core-sheath composite fiber, and the base net is formed from a regular filament yarn. A large number of artificial hairs are planted by hand on the base net, and a coating body is appropriately sewn inside the base net.
[0071]
The component of the regular filament of the filament yarn forming the base net is preferably a polymer constituting the sheath component of the amorphous inverted core-sheath composite fiber, and this component is spun to obtain a regular filament.
[0072]
In the present invention, by using an amorphous inverted core-sheath type composite fiber for artificial hair, the artificial hair is easily set by heat setting at a temperature higher than the softening point of the core component and lower than the softening point of the sheath component. A form can be imparted and the form can be stably maintained. Moreover, the form can be repeatedly changed by heat setting. Although it is possible to use the composite multifilament yarn for the base net, there is no particular merit and it is not normally performed.
[0073]
Example 8
Hereinafter, embodiments of the present invention shown in the drawings will be described in detail. 1 to 4 show an embodiment of the wig X of the present invention.
[0074]
Reference numeral 1 denotes a base net capable of covering the scalp. The base net 1 is a cap-like shape so that the scalp can be covered from the peripheral edge 1a sewn on an annular cloth and the peripheral edge 1a. And a knitted portion 1b for flocking knitted into a hair.
[0075]
In this example, the b polymer which is a component of the regular filament of the filament yarn used for forming the base net is polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) having an acid component of 100% terephthalic acid. A spun regular filament was used to obtain a 480d / 12f raw yarn, which was crushed and dyed and further knitted to obtain a base net 1.
[0076]
Reference numeral 2 denotes a large number of artificial hairs 2 planted so as to protrude outwardly from the knitted portion 1 b for flocking of the base net 1. In this embodiment, the component of the composite filament of the filament yarn used for forming the artificial hair 2 is a polymer for the core component and b polymer for the sheath component.
[0077]
More specifically, in Example 8, as a polymer, isophthalic acid accounts for 25 mol% of the acid component, and has a softening point of about 150 ° C. having substantially no melting point peak as measured by DSC method. Polymerized polyethylene terephthalate as a core component, b polymer, polyethylene terephthalate used for the regular filament as a sheath component, and two types of core-sheath type composite filaments having different thicknesses, each having a core / sheath volume ratio of 1/1 The yarn was spun and used as 880d / 16f and 560d / 12f yarns for dyeing. Two types of artificial hair 2 (A8, B8) were obtained using these two types of yarns, respectively.
[0078]
In the following examples, as a polymer, polypropylene having a softening point of about 155 ° C. is used as a core component, and b polymer is colored by mixing carbon black, petal and titanium yellow pigment with 6-nylon having a softening point of about 230 ° C. Two types of core-sheath type composite filaments having different thicknesses as a sheath component were spun at a core / sheath volume ratio of 1/2, and this was used as yarns of 720d / 16f and 600d / 12f. . Using these two types of yarns, two types of artificial hair 2 (C8, D8) were obtained.
[0079]
3 is a coating body integrally attached to the inside of the knitted portion 1b for flocking of the base net 1, and this coating body 3 is made of a synthetic resin material and a rubber material such as natural rubber or synthetic rubber. These materials were dissolved in a solvent to obtain a liquid coating material, which was poured into a desired mold to obtain a tape-shaped coating body 3.
[0080]
The base net 1 and the coating body 3 obtained above were applied to both Examples 1 and 2, and the two types of artificial hair 2 (A8, B8) of Example 1 and the two types of artificial hair 2 of Example 2 ( C8, D8) were used respectively to obtain four types of wigs (A8, B8, C8, D8) according to the present invention.
[0081]
These wigs (A8, B8, C8, D8) according to the present invention and wigs manufactured by the method disclosed in Japanese Patent Laid-Open No. 6-173106 as a comparative sample are used in a hairstyle set (on a hot curler having a surface temperature of 150 ° C.). ), Ease of hairstyle, and repeatability of the hairstyle set. As a result, the wig according to the present invention was clearly superior in any test.
[0082]
Furthermore, using the wig (b), the relationship between the hairstyle setting temperature and the setting effect was tested and evaluated by the following methods (1) to (4).
(1) Wrap the hair at a curler surface temperature of 83 ° C. and leave it for 30 minutes, (×) (2), warm in the oven at 120 ° C. for 10 minutes with the hair wrapped around the curler, (◯)
(3) Set the hair at 5 cm (120 to 150 ° C.) from the outlet of the hair dryer, (○)
(4) Set the hair for 5 seconds with a commercially available hot curler, (○)
In addition, as an evaluation method, the state after setting was visually determined, and from the actual feeling actually worn, satisfaction (O) and dissatisfaction were (X). From the above results, it is preferable to set at 120 ° C. or higher in order to obtain good setting properties.
[0083]
As an example other than the above, antibacterial fine powder 4 such as zeolite fine powder and inorganic fine powder can be mixed in the base net 1, artificial hair 2 and coating body 3 respectively. At that time, the antibacterial fine powder 4 is encapsulated in the base net 1, the artificial hair 2 and the coating body 3 respectively, and at the same time, as shown in FIG. 3 and FIG. Exposed on the outer surface.
[0084]
As yet another embodiment, zirconium carbide and any one or more of zinc, silver, and copper can be mixed with the artificial hair 2 in order to exhibit deep colorability and weather resistance.
[0085]
(6) Description of composite yarn using amorphous inverted core-sheath composite fiber on the outside
Different shrinkage mixed fiber, conjugated bulky yarn, and slab yarn (hereinafter referred to as composite yarn) using amorphous inverted core-sheath composite fiber will be described.
[0086]
Such a composite yarn is a yarn composed of two types of high and low multifilaments having different boiling water shrinkage rates or residual elongations. The filament is located. In both slab yarn and spandex, the wound yarn side forms the outside of the yarn.
[0087]
In such a composite yarn, waterproofness and shape stability are imparted to the entire yarn by using an amorphous inverted core-sheath composite fiber in advance for the multifilament located outside the yarn after the treatment. .
[0088]
Thus, even if the target yarn is any one of a different shrinkage mixed yarn, a conjugating bulky yarn, and a slab yarn, as a multifilament of a thermoplastic synthetic fiber combined with an amorphous inverted core-sheath composite fiber, And regular type polyamide, polyester, polyolefin and the like having fiber forming ability.
[0089]
Again, the configuration of each yarn will be described in detail. In the case of a different shrinkage mixed fiber, the amorphous inverted core-sheath composite fiber has a low boiling water shrinkage side multi-fiber with a boiling water shrinkage rate of about 8%. Used as a filament. Regular type multifilaments are used as multifilaments on the high boiling water shrinkage side with a boiling water shrinkage of around 20%. The process of fluid entanglement of the two may be either a false twisting process through a spinning-drawing process or a direct spinning drawing process.
[0090]
In such a different shrinkage mixed fiber, the fiber on the low boiling water shrinkage rate side (amorphous inverted core-sheath type composite fiber) forms the outside of the yarn by the boiling water shrinkage treatment after forming the knitted fabric.
[0091]
Subsequently, when this is heat-set under pressure, the low shrinkage component (amorphous inverted core-sheath composite fiber side) has morphological stability as described above, and the bulky shape is stably maintained.
[0092]
Similarly, in the conjugated bulky yarn, the amorphous inverted core-sheath type composite fiber is used as a high elongation processed yarn. Other constituent yarns are used as low elongation processed yarns. The difference in elongation between the two is 50% or more. As a result, when formed into a final product, the amorphous inverted core-sheath type composite fiber located outside the composite yarn has shape stability and also has a bulge, so that the bulky shape of the entire fabric is stabilized. Hold and have less sag.
[0093]
Also, in slab yarn, the use of amorphous inverted core-sheath type composite fiber for the sheath yarn and regular type multifilament for the core yarn enables the form safety of the single and multiple spiral parts formed by the sheath yarn. The slab part is firmly fixed and does not come apart.
[0094]
In such a composite yarn, in the composite yarn comprising a combination of monofilaments or multifilaments of a plurality of types of thermoplastic synthetic fibers such as different shrinkage mixed yarn, conjugating bulky yarn, slab yarn, and others, spandex, covering yarn, etc. By using an amorphous inverted core-sheath type composite fiber for the multifilament located outside the yarn as in the above, it is possible to achieve high form stability in the fiber structure such as knitted fabric, woven fabric and yarn obtained by the composite yarn. And imparts water resistance and water resistance.
[0095]
Example 9
Hereinafter, although an Example is described concretely, the water pressure resistance in an Example is based on JIS L-1092A method (hydrostatic pressure method).
[0096]
The form stability is 100 g / cm when the sample is wound around a glass tube with a diameter of 10 mm, heat-set, cooled and spread. ² The loaded state when the load was applied and the load was removed after 5 minutes was visually judged, and the test result of ◯ indicates good, Δ indicates normal, and X indicates failure.
[0097]
50d / 24f obtained from a polyethylene terephthalate resin having an intrinsic viscosity of 0.64 as a raw material and subjected to a spinning-stretching-heat setting step, a semi-stretched highly shrinkable filament having a boiling water shrinkage of 20.0%, and isophthalic acid is an acid. Polyethylene terephthalate having a softening point of about 150 ° C. and having an acid component of 100% terephthalic acid (melting point: 255 ° C.) occupying 25 mol% of the component and having substantially no melting point peak as measured by the DSC method The core-sheath composite stretched low-shrinkage filament having a core-sheath ratio (volume ratio) of 1: 1, 50d / 24f and a boiling water shrinkage of 8.0% is combined after spinning. At the same time, the yarn was inserted into an interlace nozzle, fluid entangled in both yarns, mixed and wound around a bobbin.
[0098]
A plain fabric was woven using the blended yarn as a weft and a 50d / 48f raw yarn of regular polyester having an acid component of 100% terephthalic acid as a warp to obtain a fabric of Example 9.
[0099]
On the other hand, after spinning, 100% regular polyester 50d / 18f, semi-stretched highly shrinkable filament with boiling water shrinkage 20.0%, and polyester 50 / 18f with the same composition, low shrinkage filament with boiling water shrinkage 8.0% These yarns were combined, and these were simultaneously inserted into the interlace nozzle under the same conditions as in Example 1, and the two yarns were fluid entangled, mixed, and wound on a bobbin.
[0100]
A plain weave was woven using the blended yarn as a weft and a 50d / 48f yarn of regular polyester having an acid component of 100% terephthalic acid as a warp to obtain a fabric of Comparative Example 1.
[0101]
In the fabric of Example 9 and Comparative Example 1, 35 kg / cm ² After the heat treatment (calendering) at 170 ° C. in the pressurized state, the water pressure resistance and the shape stability of this fabric were measured. The results are shown in Table 6.
[Table 6]

[0102]
Example 10
As the polyester stretched yarn, isophthalic acid accounts for 25 mol% of the acid component, cored with a copolymerized polyethylene terephthalate having a softening point of about 150 ° C. having substantially no melting point peak as measured by DSC method, and the acid component is terephthalic acid 100 % Core sheath ratio (volume ratio) with a polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) of 1: 1, and a core sheath having a residual elongation of 150% obtained through the spinning drawing heat setting step A type composite semi-drawn yarn (108d / 36f) was used, and this was combined with a polyester drawn yarn (residual elongation of 30%), and this was formed into a false twisted yarn under the conditions shown below. A plain fabric was woven using this false twisted yarn for both warp and weft to obtain a fabric of Example 10.
[0103]
False twisting conditions
Spindle speed: 250,000R / M
Number of twists: 2,530 T / M
Heater temperature: 180 ° C
Feed rate: -5%
Winding rate: + 6.2%
On the other hand, both a regular polyester stretched yarn (108d / 36f) and a regular polyester unstretched yarn (108d / 36f) were combined and false twisted under the same conditions as in Example 2 to obtain a false twisted yarn. It was.
[0104]
A plain fabric was woven using this false twisted yarn for both warp and weft to obtain a fabric of Comparative Example 2.
[0105]
In the fabric of Example 10 and Comparative Example 2, 35 kg / cm ² After the heat treatment (calendering) at 170 ° C. in the pressurized state, the water pressure resistance and the shape stability of this fabric were measured. The results are shown in Table 7.
[Table 7]

[0106]
Example 11
A 50d / 48f stretched polyester yarn is used as the synthetic fiber multifilament yarn to be the core yarn, and the sheath yarn is isophthalic acid, which accounts for 25 mol% of the acid component, and has substantially no melting point peak as measured by the DSC method. Core-sheath ratio (volume ratio) 1: 1 of copolymer terephthalate having a point of about 150 ° C. as a core component and polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) whose acid component is 100% terephthalic acid as a sheath component A core-sheath type composite fiber (50d / 48f) was used, and this and the drawn yarn were passed through a normal false twisting process under the following conditions to obtain a slab yarn raw yarn.
[0107]
The slab yarn was heat treated at 170 ° C. to fix the sheath yarn, and then wound up to complete the slab yarn. This slab yarn did not move the sheath part at the time of knitting, and was excellent in appearance and texture different from conventional products.
False twisting conditions
Spindle speed: 185,500R / M
Number of twists: 3,040 T / M
Heater temperature: 200 ° C
False twist feed rate: -3.1%
Winding rate: + 6.2%
Winding thread tension: 0 to 1 g / d
[0108]
Example 12
Using a polyester stretch yarn of 62d / 48f and a boiling water shrinkage of 20% as the core yarn, and forming a core-sheath structure yarn by false twisting using a polyester semi-drawn yarn of 50d / 48f boiling water shrinkage of 8% as the sheath yarn did.
[0109]
After the sheath of the yarn was scraped to form a slab due to yarn slippage intermittently on the core yarn, isophthalic acid accounted for 25 mol% of the acid component on the outer periphery of the yarn, and the measurement was performed by the DSC method. The core component is copolymerized polyethylene terephthalate having a softening point of about 150 ° C., which has substantially no melting point peak, and the sheath component is polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) whose acid component is 100% terephthalic acid. A semi-stretched yarn having a core-sheath composite fiber having a core-sheath ratio (volume ratio) of 1: 1 was wound to obtain a slab yarn raw yarn. The core-sheath type composite fiber is wound in order to fix the sheath yarn of the yarn having a slab to the core yarn.
[0110]
The slab yarn was heat treated at 170 ° C. to fix the core-sheath type composite fiber, and then wound up to complete the slab yarn. This slab yarn was useful because the core-sheath type composite fiber had form stability, so that the slab part was not scattered at all and the fabric surface could be formed as designed.
[0111]
(7) Explanation of composite yarn using amorphous inverted core-sheath type composite fiber on the inside
A composite yarn using an amorphous inverted core-sheath composite fiber on the inside, specifically, a different shrinkage blended yarn, a bulky processed yarn, a slab yarn, a ring yarn, a molding yarn, and other design yarns will be described.
[0112]
Other fibers combined with the amorphous inverted core-sheath composite fiber are made of thermoplastic synthetic fibers such as polyester, polyamide and polyolefin, natural fibers such as cotton, silk and wool, and artificial fibers such as rayon and acetate. At least one selected fiber.
[0113]
When the composite yarn is a different shrinkage mixed yarn, it is selected from the group consisting of thermoplastic synthetic fibers such as polyester, polyamide and polyolefin, natural fibers such as cotton, silk and wool, and artificial fibers such as rayon and acetate. Two or more types of yarns having different boiling water shrinkage rates, and the high shrinkage yarns are located inside the yarns by the shrinkage treatment after blending. Therefore, an amorphous inverted core-sheath type composite fiber is used as the yarn on the high shrinkage rate side. Further, the bulky processed yarn has an elongation difference selected from the group consisting of thermoplastic synthetic fibers such as polyester, polyamide and polyolefin, natural fibers such as cotton, silk and wool, and artificial fibers such as rayon and acetate 2 It consists of yarns of more than seeds, and the low elongation processed yarn is located inside the yarn by false twisting after the combined yarn. Therefore, an amorphous inverted core-sheath type composite fiber is used as the low elongation processed yarn. Naturally, the slab yarn uses an amorphous inverted core-sheath type composite fiber for the core yarn because the core yarn forms the inside of the yarn.
[0114]
That is, in this composite yarn, a high degree of form stability is imparted by using an amorphous inverted core-sheath composite fiber as a yarn located inside the composite yarn.
[0115]
Again, the configuration of each composite yarn will be described more specifically. First, in the case of different shrinkage mixed yarn, the amorphous inverted core-sheath type composite fiber has a high boiling water shrinkage with a boiling water shrinkage of 10 to 30%. Used as a rate side yarn. The other constituent yarn is used as a low boiling water shrinkage yarn having a boiling water shrinkage of 0 to 15%, and the difference in shrinkage between the amorphous inverted core-sheath composite fiber and the other constituent yarn is 5% or more, preferably Select to be 10% or more. The process of fluid entanglement may be any of during the spinning process, during the stretching process, during the subsequent fiber mixing process, or during the direct spinning and stretching process.
[0116]
In such a different shrinkage mixed yarn, the fiber on the high boiling water shrinkage rate side (amorphous inverted core-sheath type composite fiber) is mainly located inside the yarn due to the boiling water shrinkage treatment after forming the knitted fabric. Next, by heat setting, as described above, the high shrinkage component (amorphous inverted core-sheath composite fiber side) has form stability. Therefore, the properties such as swelling of the fiber on the low shrinkage rate side are not impaired while maintaining the form stability.
[0117]
Next, in a bulky processed yarn, the amorphous inverted core-sheath composite fiber is used as a low elongation processed yarn. Other constituent yarns are used as high elongation processed yarns. The difference in elongation between the two is 50% or more. As a result, when formed into the final product, the amorphous inverted core-sheath type composite fiber located inside the composite yarn has shape stability, and the other constituent yarn located outside has a bulge, The composite yarn as a whole has a bulky shape and excellent texture.
[0118]
Moreover, in the slab yarn, by using an amorphous inverted core-sheath type composite fiber for the core yarn and using other constituent yarns for the sheath yarn, the entire fabric has excellent shape stability, and the slab yarn is The original appearance quality and texture are not lost.
[0119]
In order to exhibit the form stability using the composite yarn in the present invention, it is preferable to use the composite yarn at least 30% or more, more preferably 50% or more of the entire fabric. Further, when pleating or crease processing is performed in the warp or weft direction of the woven fabric, it is desirable to use at least 25% or more, preferably 30% or more, more preferably 40% or more of the yarn perpendicular to the pleating line.
[0120]
Example 13
Polyethylene whose isophthalic acid accounts for 25 mol% of the acid component, has a softening point of about 150 ° C. and has substantially no melting point peak as measured by the DSC method, and has a core component of 100% terephthalic acid. A core-sheath composite filament having terephthalate (melting point: 255 ° C., softening point: 240 ° C.) as a sheath component (volume ratio) of 1: 1, 50 d / 24 f and a boiling water shrinkage of 21.0% and an intrinsic viscosity of 0. A 50d / 48f made of 64 polyethylene terephthalate and a low-shrinkage filament with a boiling water shrinkage of 8.0% (drawn) are combined with each other after drawing, and simultaneously inserted into an interlace nozzle, and fluid entanglement is applied to both yarns. It was wound around a fine bobbin. Weaving a plain woven fabric with a warp / weft density of 110 / in × 80 / in using a 50d / 48f yarn of regular polyester with an acid component of 100% terephthalic acid as a warp. The fabric of Example 13 was obtained.
[0121]
On the other hand, instead of the core-sheath type composite filament of Example 13, a regular polyester having a 22% boiling water shrinkage of 22% was used, and after that, the mixture was mixed under the same conditions as in Example 13 and driven into the weft. A woven fabric was obtained.
[0122]
The fabrics of Example 13 and Comparative Example 3 were dyed with a normal polyester fabric and finished, and then heat-set for shape stability was performed, and the shape stability of each fabric was measured. The results are shown in Table 8.
[0123]
[Table 8]

[0124]

A plain fabric was woven using this processed yarn for both warp and weft to obtain a fabric of Example 14.
[0125]
False twisting conditions
Spindle speed: 250,000R / M
Number of twists: 2,530 T / M
Heater temperature: 180 ° C
Feed rate: -5%
Winding rate: + 6.2%
On the other hand, a regular polyester stretched yarn (75d / 36f) with a residual elongation of 28% and a regular polyester semi-stretched yarn (115d / 36f) with a residual elongation of 121% were combined, and Example 14 and False twisting was performed under the same conditions to obtain a false twisted yarn of 200d / 72f).
[0126]
A plain fabric was woven using this false twisted yarn for both warp and weft to obtain a fabric of Comparative Example 4.
[0127]
The woven fabrics of Example 14 and Comparative Example 4 were subjected to the same processing as in Example 13, and the shape stability was measured. The results are shown in Table 9.
[0128]
[Table 9]

[0129]
Example 15
Polyethylene whose isophthalic acid accounts for 25 mol% of the acid component, has a softening point of about 150 ° C. and has substantially no melting point peak as measured by the DSC method, and has a core component of 100% terephthalic acid. A core-sheath composite fiber (50d / 24f) having a core-sheath ratio (volume ratio) of 1: 1 having a sheath component of terephthalate (melting point: 255 ° C., softening point: 240 ° C.) is used as the core yarn, and the sheath yarn is 50 d / 96 f. A false twisted slab yarn of Example 15 was obtained by using a polyester drawn yarn and passing through a normal false twist process under the following conditions.
[0130]
Spindle speed: 185,500R / M
Number of twists: 3,040 T / M
Heater temperature: 200 ° C
Overfeed rate of sheath yarn: + 50%
False twist feed rate: -3.1%
Winding rate: + 6.2%
Winding thread tension: 0 to 1 g / d
On the other hand, a slab yarn of Comparative Example 3 was produced under the same conditions as in Example 15 except that a 50d / 24f polyethylene terephthalate yarn having an acid component of 100% terephthalic acid was used instead of the core-sheath composite fiber.
[0131]
The slab yarns of Example 15 and Comparative Example 4 obtained in this way were weaved into warp yarns of a satin woven fabric (five pieces of three satin 3 jumps) using 75d / 36f normal processed yarn. In Example 15-1, the slab yarn produced by the above method accounts for 25% of the weft, and Example 15-2 accounts for 50%. In Comparative Example 4, the slab yarn accounts for 50% of the weft. After subjecting the fabric to normal polyester processing, the shape stability was measured. The results are shown in Table 10.
[0132]
[Table 10]

[0133]
(8) Description of embossed fabric
The embossing process for the fabric using the reversible core-sheath composite fiber will be described.
[0134]
The multifilament in which the constituent single yarn is constituted by the amorphous inverted core and the sheath type composite fiber is used for a part or all of the warp and / or the weft. The use ratio is the lowest when it is used only for warp or weft, but even in such a case, it is used for at least 30%. If this is less than 30%, the waterproofness and form stability will be poor, and the object of the present invention cannot be achieved. Naturally, the arrangement state on the warp or the weft is uniform, and the union is essentially preferable. Examples of the multifilament that interweaves with the amorphous inverted core-sheath composite fiber include a regular type polyamide filament and a polyester filament multifilament, and processed yarns thereof.
[0135]
In such fabrics, the fabric cover factor in the warp and weft directions [fineness (denier) ^0.5 X When the sum of the number of driving (lines / inch) is TCF, it is necessary to set the range of TCF to 800>TCF> 2500. Is difficult to clarify, and when it is 800 or less, it is difficult to weave a durable fabric.
[0136]
The woven fabric using the amorphous inverted core-sheath type composite fiber is a scouring process that is a pre-treatment before weaving and a normal embossing process, a relaxation process using a liquid flow, a dyeing process performed as necessary, and After passing through the finishing process, etc., it is sent to the embossing calendar processing machine.
[0137]
In a normal embossing calendering machine, both a hard heating roll with a convex pattern engraving and a concave soft roll that is paired with it are rotated while pressing with appropriate pressure, and the embossed calender is pressed between the two rolls. The embossed pattern is formed by introducing the target fabric. The height difference between the convex portion and the concave portion needs to be 1 mm or more, and if it is less than 1 mm, it is difficult to form a sufficient uneven pattern.
[0138]
The fabric according to the present invention does not depend on the unevenness of the fabric by pressurization under heating, but the core component or sheath component made of an amorphous polymer with a low softening point is used as a hard heating roll for an embossing machine. A convex pattern drawn on the heating roll is formed on the woven fabric by pressing and by deforming and increasing the filament diameter.
[0139]
In the apparatus for producing the woven fabric of the present invention from the deformation state of the woven fabric in the embossing process, the height difference between the convex portion and the concave portion for pattern formation is not so necessary. For this reason, pattern formation can be easily performed even with a combination of a hard heating roll having a convex pattern and a soft roll having a smooth surface. Normally, the pressure applied to the embossing roll pair is 10 kg / cm. ² Although required to a certain extent, the fabric according to the present invention is 5 kg / cm. ² It is possible to carry out with a degree.
[0140]
One of the important processing conditions for obtaining the fabric of the present invention is the surface temperature of a hard heating roll having a pattern.
[0141]
When a regular polyester fiber or regular polyamide fiber is used as the sheath component of the amorphous inverted core-sheath composite fiber, the surface temperature is suitably in the range of 160 to 190 ° C., and the contact pressure time is 1 second or more If so, it is possible to produce an embossed fabric that is clear and excellent in durability.
[0142]
Example 16
The following three types of raw yarns were prepared.
The raw yarn a16-isophthalic acid (IPA) occupies 25 mol% of the acid content, and has a softening point of about 150 ° C. and has substantially no melting point peak as measured by DSC method. A core-sheath type composite fiber having a sheath of polyethylene terephthalate (melting point: 255 ° C., softening point: 240 ° C.) whose terephthalic acid is 100% was spun at a core-sheath ratio (volume ratio) of 1: 1 to obtain a 75 d / 24 f yarn. .
Raw yarn c16-75d / 24f yarn of regular polyester with an acid content of 100% terephthalic acid.
[0143]
Each of these two types of raw yarns was subjected to additional twisting of 1000 T / M to obtain test wefts. On the other hand, a regular polyester 75d / 36f yarn having an acid component of 100% terephthalic acid was subjected to additional twisting of 1000 T / M to obtain a common test warp.
[0144]
The warp and weft thus obtained were woven into plain weaves with a warp density of 71 yarns / inch and a weft density of 75 yarns / inch, respectively, using a WJL loom. Embossing raw fabrics A16 and C16 were prepared by relaxing by liquid flow, preliminary setting at 190 ° C, dyeing at 130 ° C, and finishing set at 160 ° C.
[0145]
Embossing completed by putting these two fabrics A16 and C16 on an embossing machine and passing between a heated roll (170 ° C) with a predetermined floral pattern and a soft rubber roll (room temperature) having a flat surface. A woven fabric was obtained. The contact pressure of both rolls is 5 kg / cm ² The contact time is 1 second. Table 11 shows the test results of the form stability immediately after the embossing of the three kinds of processed fabrics and after 10 washings. The form stability is 100 g / cm when the test fabric is wound around a glass tube with a diameter of 10 mm, heat-set, cooled and spread. ² After 5 minutes, the wound state and the residual state of the floral pattern were visually determined after 5 minutes.
[0146]
[Table 11]

[0147]
In the present invention, the fabric cover factor in the warp direction is the warp density (lines / inch) × (warp denier) ^0.5 The fabric cover factor in the weft direction means the weft density (lines / inch) × the square root of the weft denier. The TCF defined in the present invention is the sum of the two.
[0148]
(9) Explanation of water resistant fabric
The inverted core-sheath type composite fiber having a melting point of the core component lower than the melting point of the sheath component can obtain excellent water resistance by applying pressure heat treatment such as calendering to a fabric using the same. It is preferable to use it for fabrics and bag fabrics. Hereinafter, such a water resistant fabric will be described.
[0149]
In such an invention, monofilaments are not suitable for weaving yarns because they are rendered water-impermeable by heat setting under high pressure. The bag material is required to be a multifilament having a total denier of 100 denier or more, preferably 200 to 500 denier. If the total denier is less than 100 denier, the physical properties as a bag fabric are insufficient.
[0150]
The single yarn denier is usually preferably about 4 to 15 denier, and the single yarn strength needs to be 2 g / d or more.
[0151]
Moreover, as the cloth for umbrellas, it is necessary that the total denier is a multifilament of 300 denier or less, preferably 30 to 150 denier. When the total denier exceeds 300 denier, the fabric for the umbrella lacks fineness, while when it becomes thinner than 30 denier, handling becomes difficult due to insufficient strength and excessive flexibility.
[0152]
The single yarn denier is usually preferably 1 to 8 denier, and the single yarn strength needs to be 2 g / d or more.
[0153]
The said multifilament which comprised the constituent single yarn by the reversible core-sheath-type composite fiber is used for the one part or all part for warp and / or weft. The usage ratio is the lowest when it is used only for warp or weft, but even in such a case, it is used for at least 20%. If this is less than 20%, the waterproofness and form stability will be poor, and the object of the present invention cannot be achieved. Naturally, the arrangement state on the warp or the weft is uniform, and the union is essentially preferable.
[0154]
Examples of the multifilaments that interweave with the reversible core-sheath composite fiber include polyamide filaments, polyester filament multifilaments, and processed yarns that are usually used as fabrics.
[0155]
A water-resistant woven fabric is woven using such yarns for warp and / or weft, but in order to obtain sufficient waterproofness, it is necessary to increase the density during weaving. Fabric cover factor in warp and weft directions [(Fineness (denier)) ^0.5 X × the number of driving (lines / inch)] is TCF, it is important that the density be in the range of 3500>TCF> 800, preferably in the range of 3500>TCF> 1200. When the TCF is less than 800, the gap of the woven structure cannot be sufficiently filled by heat setting under pressure using calendaring or the like, and when it is 3500 or more, the weaving property is difficult. The woven fabric used is preferably a plain weave and its modified weave, a twill weave and its modified weave, a satin weave and its modified weave.
[0156]
In addition, the fabric according to the present invention essentially does not need a water repellent finish and a waterproof finish, and has an important feature in that respect. However, if necessary, these treatments can be performed by known methods. I can do it. For example, an acrylic, silicon, or fluorine-based water repellent can be applied by a method such as spraying, batching, dipping, or coating.
[0157]
Further, the core component of the reversible core-sheath composite fiber used in such a water-resistant fabric has a softening point of the core component measured by the thermomechanical analysis method of JIS K 7196, which is 20 ° C. lower than the softening point of the sheath component. It is preferable to use a substantially amorphous polymer in which the core component does not cause a melting point peak in a differential thermal analysis method in which the core component is heated at a heating rate of 10 ° C./min in a nitrogen atmosphere.
[0158]
Example 17
Hereinafter, although an Example is described concretely, the water-resistant pressure in an Example is based on JIS L-1092A method (hydrostatic pressure method), and form stability winds a sample around a glass tube with a diameter of 10 mm, Heat set at 160 ° C for 3 minutes, cool and spread 100g / cm ² After 5 minutes, the winding state when the load was removed was visually judged.
[0159]
The following two types of yarns were prepared for bags.
Isophthalic acid (IPA) occupies 25 mol% of the acid component and is substantially amorphous with no melting point peak produced by differential thermal analysis (DSC method) in which heating is performed at a heating rate of 10 ° C./min in a nitrogen atmosphere. A core-sheath type composite fiber having a core of copolymer polyethylene terephthalate having a softening point of 150 ° C. and a polyamide as a sheath was spun at a core-sheath ratio (volume ratio) of 1: 1 to obtain a yarn of 210d / 16f. This was designated as raw yarn a17.
On the other hand, a yarn of 210d / 16f made of regular polyamide obtained by a normal process was used as a raw yarn b17.
[0160]
A plain woven fabric is manufactured using the raw yarn a17 and the raw yarn b17 as the warp and weft, respectively, so that the weft density of the processed lift is 64 / inch × 46 / inch, and each of these fabrics is a polyester plain woven fabric. The finishing process including dyeing (liquid flow dyeing machine) and heat setting under pressure was performed in the same process and conditions as the processing of the polyamide plain fabric.
The bag fabric obtained in this manner was not subjected to water repellent treatment on the original yarn a17, and was subjected to normal water repellent treatment on the original yarn b17 using a fluorine-based water repellent.
[0161]
As a result of measuring both waterproofness and form stability, the results shown in Table 12 were obtained.
[Table 12]

[0162]
The following two types of raw yarns were prepared for umbrella use.
A yarn of 75d / 24f made of the same components as the core-sheath conjugate fiber used for the raw yarn a17 of Example 17 is defined as a raw yarn c17. On the other hand, a 75 d / 24 f yarn made of regular polyester obtained by a normal process is used as a raw yarn d14.
[0163]
A plain fabric is formed by using the raw yarn c17 and the raw yarn d17 as a warp and a weft, respectively, so that the density of warp and weft during processing is 100 yarns / inch × 90 yarns / inch, and this fabric is designated as A17 fabric. On the other hand, using the original yarn d17 as both the warp and weft, a plain weave is formed so that the warp weft density of the work lift is 100 / inch × 90 / inch, and this fabric is designated as B17.
The umbrella fabric thus obtained was scoured at 95 ° C. → Set at 185 ° C. for 20 seconds → Dyeing using a beam dyeing machine → 120 ° C. coating with acrylic resin → 170 ° C. water repellency with fluororesin Two kinds of umbrellas completed by processing were obtained. As a result of measuring both waterproofness and form stability, the results shown in Table 13 were obtained.
[0164]
[Table 13]

In the present invention, the fabric cover factor TCF is [(fineness (denier)) of warp and weft. ^0.5 X number of driven-in (lines / inch)].
[0165]
