従来、合成繊維や天然繊維などからなる立毛布帛が巾広い用途で使用されている。例えば、立毛布帛は保温性に優れることから、衣料用としてはコートやジャケットのようなアウター衣料、フリースやトレーナーといったミドラー衣料、シャツや肌着といったインナー衣料などに広く使用されている。また、毛布などの寝具、椅子やソファーの表皮材、カーペット、カーシートといった寝装寝具やインテリア用品にも幅広く使用されている。さらには、立毛布帛は吸水性にも優れることから、スウェットやジャージといったスポーツ衣料やおしめや介護用シーツといった医療・衛生用途にも広く使用されている。 Conventionally, a napped fabric made of synthetic fiber or natural fiber has been used for a wide range of purposes. For example, napped fabrics are widely used for clothing, such as outer clothing such as coats and jackets, midler clothing such as fleece and trainers, and inner clothing such as shirts and underwear. It is also widely used in bedding such as blankets, bedding and interior items such as chairs and sofas, carpets, and car seats. Furthermore, since the napped fabric is excellent in water absorption, it is also widely used for medical / hygiene applications such as sports clothing such as sweat and jersey, diapers and nursing sheets.
しかしながら、これらの立毛布帛は、湿度や水分が変化しても立毛高さが常に一定で、湿度や水分を感じて毛足長さが変化するといった動物の毛のような性質を有するものではなかった。 However, these raised fabrics do not have animal-like properties such that the raised hair height is always constant even when the humidity and moisture change, and the length of the hair foot changes by sensing the humidity and moisture. It was.
他方、特許文献１では、ポリエステルとポリアミドの異質ポリマーを貼りあわせたサイドバイサイド型複合繊維を用いた通気性自己調節織編物が提案されている。また、本発明者らは、特願２００４−２５６６２８号において、ポリエステル成分とポリアミド成分とが接合された複合繊維であって、性能のよい通気性自己調節織編物を得ることが可能な複合繊維を提案している。
本発明は上記の背景に鑑みなされたものであり、その目的は、捲縮繊維を立毛部に含む立毛布帛であって、湿潤時に捲縮繊維の捲縮率が可逆的に低下することにより立毛高さが大きくなり、その結果、立毛部が衣服の内側に位置するように立毛布帛を使用すると、発汗時にムレ感や濡れ感を低減させることが可能な立毛布帛および該立毛布帛を用いてなる繊維製品を提供することにある。 The present invention has been made in view of the above-described background, and an object of the present invention is a napped fabric including a crimped fiber in a napped portion, and the napped fiber is formed by reversibly reducing the crimp rate of the crimped fiber when wet. As a result, when the raised fabric is used so that the raised portions are located inside the clothes, the raised fabric that can reduce the feeling of stuffiness and wetness when sweating and the raised fabric are used. To provide textile products.
本発明者らは上記の課題を達成するため鋭意検討した結果、湿潤により捲縮率が低下する捲縮繊維を立毛部に配すことにより、所望の立毛布帛および繊維製品が得られることを見出し、さらに鋭意検討を重ねることにより本発明を完成するに至った。 As a result of intensive studies to achieve the above-mentioned problems, the present inventors have found that desired napped fabrics and fiber products can be obtained by arranging the crimped fibers whose crimp rate is reduced by wetting in the napped portions. The present invention has been completed by further intensive studies.
かくして、本発明によれば「カットパイルおよび／またはループパイルからなる立毛部と地組織部とで構成される立毛布帛であって、前記立毛部に、湿潤時に捲縮率が低下する捲縮繊維Ａが含まれることを特徴とする立毛布帛。」が提供される。
ここで、前記の捲縮繊維Ａにおいて、乾燥時の捲縮率ＤＣ（％）と湿潤時の捲縮率ＨＣ（％）との差ＤＣ−ＨＣが０．５％以上であることが好ましい。
Thus, according to the present invention, “a raised fabric comprising a raised portion and a ground tissue portion made of a cut pile and / or a loop pile, wherein the crimped fiber has a reduced crimp rate when wet. A raised fabric characterized in that A is included. "
Here, in the above-described crimped fiber A, it is preferable that the difference DC-HC between the crimp ratio DC (%) when dried and the crimp ratio HC (%) when wet is 0.5% or more.
ただし、乾燥時の捲縮率ＤＣ（％）と湿潤時の捲縮率ＨＣ（％）は、以下の方法により算出するものとする。すなわち、枠周：１．１２５ｍの巻き返し枠を用いて荷重：４９／５０ｍＮ×９×トータルテックス（０．１ｇ×トータルデニール）をかけて一定の速度で巻き返し、巻き数：１０回の小綛を作り、該小綛を捩じり２重の輪状にしたものに４９／２５００ｍＮ×２０×９×トータルテックス（２ｍｇ×２０×トータルデニール）の初荷重をかけたまま沸水中に入れて３０分間処理し、該沸水処理の後１００℃の乾燥機にて３０分間乾燥し、その後更に初荷重をかけたまま１６０℃の乾熱中に入れ５分間処理する。該乾熱処理の後に初荷重を除き、温度２０℃、湿度６５％ＲＨ環境下に２４時間以上放置した後、前記の初荷重および９８／５０ｍＮ×２０×９×トータルデシテックス（０．２ｇ×２０×トータルデニール）の重荷重を負荷し、綛長：Ｌ０を測定し、直ちに重荷重のみを取り除き、除重１分後の綛長：Ｌ１を測定する。更にこの綛を初荷重をかけたまま温度２０℃の水中に２時間浸漬した後取り出し、ろ紙にて軽く水を拭き取った後、初荷重および重荷重を負荷し綛長：Ｌ０’を測定し、直ちに重荷重のみを取り除き、除重１分後の綛長：Ｌ１’を測定する。次いで、以上の測定数値から下記の計算式にて、乾燥時の捲縮率（ＤＣ）と湿潤時の捲縮率（ＨＣ）を算出する。
乾燥時の捲縮率ＤＣ（％）＝｛（Ｌ０−Ｌ１）／Ｌ０｝×１００
湿潤時の捲縮率ＨＣ（％）＝｛（Ｌ０’−Ｌ１’）／Ｌ０’｝×１００
However, the crimping ratio DC (%) at the time of drying and the crimping ratio HC (%) at the time of wetness are calculated by the following methods. That is, using a rewind frame with a frame circumference of 1.125 m, load: 49/50 mN × 9 × total tex (0.1 g × total denier) and rewind at a constant speed. Made and twisted into a double ring shape with a twist of 49/2500 mN x 20 x 9 x total tex (2 mg x 20 x total denier) and placed in boiling water for 30 minutes Then, after the boiling water treatment, it is dried in a dryer at 100 ° C. for 30 minutes, and is then placed in a dry heat of 160 ° C. for 5 minutes with an initial load applied. After the dry heat treatment, the initial load was removed and the sample was allowed to stand in an environment of temperature 20 ° C. and humidity 65% RH for 24 hours or more, and then the initial load and 98/50 mN × 20 × 9 × total decitex (0.2 g × 20 × Apply a heavy load of total denier), measure the heel length: L0, immediately remove only the heavy load, and measure the heel length: L1 after 1 minute of dewetting. Furthermore, after the soot was immersed in water at a temperature of 20 ° C. for 2 hours with the initial load applied, it was taken out, and after lightly wiping off the water with a filter paper, the initial load and the heavy load were applied, and the heel length: L0 ′ was measured. Immediately remove only the heavy load and measure the heel length L1 ′ after 1 minute of dewetting. Next, the crimp rate at the time of drying (DC) and the crimp rate at the time of wetness (HC) are calculated from the above measured numerical values by the following formula.
Crimp rate during drying DC (%) = {(L0−L1) / L0} × 100
Crimp rate HC (%) when wet = {(L0′−L1 ′) / L0 ′} × 100
また、前記の捲縮繊維Ａが、ポリエステル成分とポリアミド成分とがサイドバイサイド型に接合された複合繊維であって、潜在捲縮性能が発現してなる捲縮構造を有する捲縮繊維であることが好ましい。その際、ポリエステル成分が、５−ナトリウムスルホイソフタル酸が２．０〜４．５モル％共重合された変性ポリエチレンテレフタレートからなることが好ましい。また、前記の捲縮繊維Ａが、無撚糸または３００Ｔ／ｍ以下の撚りが施された甘撚り糸であることが好ましい。 Further, the crimped fiber A is a composite fiber in which a polyester component and a polyamide component are joined in a side-by-side manner, and is a crimped fiber having a crimped structure in which latent crimping performance is expressed. preferable. In that case, it is preferable that a polyester component consists of a modified polyethylene terephthalate copolymerized with 2.0 to 4.5 mol% of 5-sodium sulfoisophthalic acid. Moreover, it is preferable that the said crimped fiber A is a non-twisted yarn or a sweet twisted yarn with a twist of 300 T / m or less.
本発明の立毛布帛において、地組織部がポリエステル繊維からなることが好ましい。また、下記式で算出する立毛高さ変化率が５％以上であることが好ましい。
立毛高さ変化率（％）＝（（ＬＷ−ＬＤ）／ＬＤ）×１００
In the raised fabric of the present invention, it is preferable that the ground tissue portion is made of polyester fibers. Moreover, it is preferable that the nap height change rate calculated by the following formula is 5% or more.
Napped height change rate (%) = ((LW−LD) / LD) × 100
ただし、ＬＤとは、立毛布帛を温度２０℃、湿度６５％ＲＨ環境下に２４時間放置した後の状態で測定した立毛高さであり、一方ＬＷとは、立毛部表面に水を１ｃｃ滴下した後、１分経過後の最大立毛高さである。
さらに、湿潤時における立毛布帛の通気性が、乾燥時よりも１０％以上高くなることが好ましい。
However, LD is the napped height measured in a state where the napped fabric is left in a temperature of 20 ° C. and a humidity of 65% RH for 24 hours, while LW is 1 cc of water dropped on the napped surface. The maximum napped height after 1 minute has elapsed.
Furthermore, it is preferable that the air permeability of the napped fabric when wet is 10% or more higher than when dry.

以下、本発明の実施の形態について詳細に説明する。
本発明の立毛布帛は有機繊維糸条からなる編織組織を有する地組織部と、立毛部とからなるものであって、前記立毛部は、前記地組織部に編みこまれ、または織りこまれ、前記地組織部から、その少なくとも１面側に伸び出ている複数の立毛糸（カットパイルおよび／またはループパイル）からなるものである。そして、前記立毛部には、湿潤時に捲縮率が低下する捲縮繊維Ａからなる立毛糸が含まれる。
Hereinafter, embodiments of the present invention will be described in detail.
The napped fabric of the present invention comprises a ground tissue part having a knitted fabric composed of organic fiber yarns, and a napped part, and the napped part is knitted or woven into the ground tissue part, It consists of a plurality of napped yarns (cut pile and / or loop pile) extending from the ground tissue portion to at least one surface side thereof. The napped portion includes napped yarns made of crimped fibers A that have a reduced crimp rate when wet.
前記の捲縮繊維Ａとしては、乾燥時の捲縮率ＤＣが１．５〜１３％、湿潤時の捲縮率ＨＣが０．５〜７％、乾燥時の捲縮率ＤＣと湿潤時の捲縮率ＨＣとの差ＤＣ−ＨＣが０．５％以上（より好ましくは１〜５％）であることが好ましい。前記捲縮率ＤＣが１．５％よりも小さいと、捲縮発現力が弱すぎ、湿潤時の捲縮変化も非常に小さくなるため、所望とする、湿潤時に捲縮繊維の捲縮率が可逆的に低下することにより立毛高さが大きくなる立毛糸が得られないおそれがある。逆に、前記捲縮率ＤＣが１３％よりも大きいと、捲縮発現力が強すぎ、湿潤時に捲縮が変化し難いため、立毛高さの変化量が小さくなるおそれがある。同時に、捲縮発現力が強すぎると、捲縮繊維が後記のような複合繊維である場合、複合繊維を形成する成分間での界面剥離が起こりやすくなるおそれもある。 As the crimped fiber A, the crimp rate DC during drying is 1.5 to 13%, the crimp rate HC when wet is 0.5 to 7%, the crimp rate DC during drying and the crimp rate DC when wet The difference DC-HC from the crimp rate HC is preferably 0.5% or more (more preferably 1 to 5%). If the crimp ratio DC is less than 1.5%, the crimp developing ability is too weak, and the crimp change when wet is very small. Therefore, the crimp ratio of the crimp fiber when wet is desired. There is a possibility that a napped yarn whose napped height increases due to reversible reduction cannot be obtained. On the other hand, if the crimp ratio DC is greater than 13%, the crimp expression is too strong, and the crimp does not easily change when wet, and therefore the amount of change in napped height may be small. At the same time, if the crimp expression is too strong, when the crimped fiber is a composite fiber as described later, interfacial peeling between components forming the composite fiber may easily occur.
ここで、前記乾燥時の捲縮率ＤＣ（％）と湿潤時の捲縮率ＨＣ（％）は、以下の方法により算出するものとする。すなわち、枠周：１．１２５ｍの巻き返し枠を用いて荷重：４９／５０ｍＮ×９×トータルテックス（０．１ｇ×トータルデニール）をかけて一定の速度で巻き返し、巻き数：１０回の小綛を作り、該小綛を捩じり２重の輪状にしたものに４９／２５００ｍＮ×２０×９×トータルテックス（２ｍｇ×２０×トータルデニール）の初荷重をかけたまま沸水中に入れて３０分間処理し、該沸水処理の後１００℃の乾燥機にて３０分間乾燥し、その後更に初荷重をかけたまま１６０℃の乾熱中に入れ５分間処理する。該乾熱処理の後に初荷重を除き、温度２０℃、湿度６５％ＲＨ環境下に２４時間以上放置した後、前記の初荷重および９８／５０ｍＮ×２０×９×トータルデシテックス（０．２ｇ×２０×トータルデニール）の重荷重を負荷し、綛長：Ｌ０を測定し、直ちに重荷重のみを取り除き、除重１分後の綛長：Ｌ１を測定する。更にこの綛を初荷重をかけたまま温度２０℃の水中に２時間浸漬した後取り出し、ろ紙にて軽く水を拭き取った後、初荷重および重荷重を負荷し綛長：Ｌ０’を測定し、直ちに重荷重のみを取り除き、除重１分後の綛長：Ｌ１’を測定する。次いで、以上の測定数値から下記の計算式にて、乾燥時の捲縮率（ＤＣ）と湿潤時の捲縮率（ＨＣ）を算出する。
乾燥時の捲縮率ＤＣ（％）＝｛（Ｌ０−Ｌ１）／Ｌ０｝×１００
湿潤時の捲縮率ＨＣ（％）＝｛（Ｌ０’−Ｌ１’）／Ｌ０’｝×１００
Here, the crimp ratio DC (%) at the time of drying and the crimp ratio HC (%) at the time of wetness are calculated by the following methods. That is, using a rewind frame with a frame circumference of 1.125 m, load: 49/50 mN × 9 × total tex (0.1 g × total denier) and rewind at a constant speed. Made and twisted into a double ring shape with a twist of 49/2500 mN x 20 x 9 x total tex (2 mg x 20 x total denier) and placed in boiling water for 30 minutes Then, after the boiling water treatment, it is dried in a dryer at 100 ° C. for 30 minutes, and is then placed in a dry heat of 160 ° C. for 5 minutes with an initial load applied. After the dry heat treatment, the initial load was removed and the sample was allowed to stand in an environment of temperature 20 ° C. and humidity 65% RH for 24 hours or more, and then the initial load and 98/50 mN × 20 × 9 × total decitex (0.2 g × 20 × Apply a heavy load of total denier), measure the heel length: L0, immediately remove only the heavy load, and measure the heel length: L1 after 1 minute of dewetting. Furthermore, after the soot was immersed in water at a temperature of 20 ° C. for 2 hours with the initial load applied, it was taken out, and after lightly wiping off the water with a filter paper, the initial load and the heavy load were applied, and the heel length: L0 ′ was measured. Immediately remove only the heavy load and measure the heel length L1 ′ after 1 minute of dewetting. Next, the crimp rate at the time of drying (DC) and the crimp rate at the time of wetness (HC) are calculated from the above measured numerical values by the following formula.
Crimp rate during drying DC (%) = {(L0−L1) / L0} × 100
Crimp rate HC (%) when wet = {(L0′−L1 ′) / L0 ′} × 100
かかる捲縮繊維Ａとしては、ポリエステル成分とポリアミド成分とがサイドバイサイド型に接合された複合繊維であって、潜在捲縮性能が発現してなる捲縮構造を有する捲縮繊維であることが好ましい。 The crimped fiber A is preferably a composite fiber in which a polyester component and a polyamide component are joined in a side-by-side manner, and is a crimped fiber having a crimped structure in which latent crimping performance is expressed.
ここで、ポリエステル成分としては、他方のポリアミド成分との接着性の点で、スルホン酸のアルカリまたはアルカリ土類金属、ホスホニウム塩を有し、かつエステル形成能を有する官能基を１個以上もつ化合物が共重合された、ポリエチレンテレフタレート、ポリプロピレンテレフタレート、ポリブチレンタレフタレート等の変性ポリエステルが好ましく例示される。なかでも、汎用性およびポリマーコストの点で、前記化合物が共重合された、変性ポリエチレンテレフタレートが特に好ましい。その際、共重合成分としては、５−ナトリウムスルホイソフタル酸およびそのエステル誘導体、５−ホスホニウムイソフタル酸およびそのエステル誘導体、ｐ−ヒドロキシベンゼンスルホン酸ナトリウムなどがあげられる。なかでも、５−ナトリウムスルホイソフタル酸が好ましい。共重合量としては、２．０〜４．５モル％の範囲が好ましい。該共重合量が２．０モル％よりも小さいと、優れた捲縮性能が得られるものの、ポリアミド成分とポリエステル成分との接合界面にて剥離が生じるおそれがある。逆に、該共重合量が４．５モル％よりも大きいと、延伸熱処理の際、ポリエステル成分の結晶化が進みにくくなるため、延伸熱処理温度を上げる必要があり、その結果、糸切れが多発するおそれがある。 Here, as the polyester component, a compound having one or more functional groups having an alkali or alkaline earth metal or phosphonium salt of sulfonic acid and having an ester forming ability in terms of adhesiveness to the other polyamide component. Preferred examples thereof include modified polyesters such as polyethylene terephthalate, polypropylene terephthalate, and polybutylene terephthalate. Among these, modified polyethylene terephthalate obtained by copolymerizing the above compound is particularly preferable from the viewpoint of versatility and polymer cost. In this case, examples of the copolymer component include 5-sodium sulfoisophthalic acid and ester derivatives thereof, 5-phosphonium isophthalic acid and ester derivatives thereof, and sodium p-hydroxybenzenesulfonate. Of these, 5-sodium sulfoisophthalic acid is preferable. As a copolymerization amount, the range of 2.0-4.5 mol% is preferable. When the copolymerization amount is less than 2.0 mol%, although excellent crimping performance can be obtained, there is a possibility that peeling occurs at the bonding interface between the polyamide component and the polyester component. On the other hand, if the copolymerization amount is greater than 4.5 mol%, the crystallization of the polyester component becomes difficult to proceed during the stretching heat treatment, and thus it is necessary to raise the stretching heat treatment temperature. There is a risk.
一方のポリアミド成分としては、主鎖中にアミド結合を有するものであれば特に限定されるものではなく、例えば、ナイロン−４、ナイロン−６、ナイロン−６６、ナイロン−４６、ナイロン−１２などがあげられる。なかでも、汎用性、ポリマーコスト、製糸安定性の点で、ナイロン−６およびナイロン−６６が好適である。 One polyamide component is not particularly limited as long as it has an amide bond in the main chain, and examples thereof include nylon-4, nylon-6, nylon-66, nylon-46, nylon-12, and the like. can give. Among these, nylon-6 and nylon-66 are preferable in terms of versatility, polymer cost, and yarn production stability.
なお、前記ポリエステル成分およびポリアミド成分には、公知の添加剤、例えば、顔料、顔料、艶消し剤、防汚剤、蛍光増白剤、難燃剤、安定剤、帯電防止剤、耐光剤、紫外線吸収剤等が含まれていてもよい。 The polyester component and the polyamide component include known additives such as pigments, pigments, matting agents, antifouling agents, fluorescent whitening agents, flame retardants, stabilizers, antistatic agents, light-resistant agents, and ultraviolet absorption agents. An agent or the like may be included.
前記のサイドバイサイド型に接合された複合繊維は、任意の断面形状および複合形態をとることができる。図１は、本発明で使用されるサイドバイサイド型に接合された複合繊維の拡大横断面図を例示したものである。通常は（イ）、（ロ）のような横断面を有する複合繊維が用いられるが、（ハ）のような偏心芯鞘型であってもよい。さらには、三角形や四角形、その断面内に中空部を有するものであってもよい。なかでも、図１の（イ）のように、丸型であることが好ましい。両成分の複合比は任意に選定することができるが、通常、ポリエステル成分とポリアミド成分の重量比で３０：７０〜７０：３０（より好ましくは４０：６０〜６０：４０）の範囲内であることが好ましい。 The composite fiber joined to the side-by-side type can take any cross-sectional shape and composite form. FIG. 1 illustrates an enlarged cross-sectional view of a composite fiber bonded to a side-by-side type used in the present invention. Usually, a composite fiber having a cross section like (A) or (B) is used, but an eccentric core-sheath type like (C) may be used. Furthermore, you may have a hollow part in the triangle, the square, and the cross section. Of these, a round shape is preferable as shown in FIG. Although the composite ratio of both components can be selected arbitrarily, it is usually in the range of 30:70 to 70:30 (more preferably 40:60 to 60:40) by weight ratio of the polyester component and the polyamide component. It is preferable.
前記複合繊維の単糸繊度、単糸数（フィラメント数）としては特に限定されないが、単糸繊度１〜１０ｄｔｅｘ（より好ましくは２〜５ｄｔｅｘ）、単糸数１０〜２００本（より好ましくは２０〜１００本）の範囲内であることが好ましい。 The single yarn fineness and the number of single yarns (number of filaments) of the composite fiber are not particularly limited, but the single yarn fineness is 1 to 10 dtex (more preferably 2 to 5 dtex), and the number of single yarns is 10 to 200 (more preferably 20 to 100). ) Is preferable.
また、捲縮構造としては、ポリアミド成分が捲縮の内側に位置し、ポリエステル成分が捲縮の外側に位置していることが好ましい。かかる捲縮構造を有する複合繊維は、後記の製造方法により容易に得ることができる。複合繊維がこのような捲縮構造を有していると、湿潤時に、内側のポリアミド成分が膨潤、伸張し、外側のポリエステル成分はほとんど長さ変化を起こさないため、捲縮率が低下する（複合繊維の見かけの長さが長くなる。）。一方、乾燥時には、内側のポリアミド成分が収縮し、外側のポリエステル成分はほとんど長さ変化を起こさないため、捲縮率が増大する（複合繊維の見かけの長さが短くなる。）。 As the crimped structure, it is preferable that the polyamide component is located inside the crimp and the polyester component is located outside the crimp. The composite fiber having such a crimped structure can be easily obtained by the production method described later. When the composite fiber has such a crimped structure, the inner polyamide component swells and stretches when wet, and the outer polyester component hardly changes in length, so that the crimp rate decreases ( The apparent length of the composite fiber is increased.) On the other hand, at the time of drying, the inner polyamide component shrinks and the outer polyester component hardly changes in length, so that the crimp rate increases (the apparent length of the composite fiber becomes shorter).
本発明の立毛布帛において、立毛部には前記の捲縮繊維Ａが立毛糸として含まれている。その際、捲縮繊維Ａが立毛部の全重量に対して３０重量%以上（より好ましくは５０重量％以上、特に好ましくは１００重量％）含まれることが好ましい。捲縮繊維Ａの含有量が３０重量％よりも小さいと、所望の立毛布帛がえられないおそれがある。 In the raised fabric of the present invention, the above-mentioned crimped fiber A is included as a raised yarn in the raised portion. At that time, it is preferable that the crimped fiber A is contained in an amount of 30% by weight or more (more preferably 50% by weight or more, particularly preferably 100% by weight) with respect to the total weight of the napped portion. If the content of the crimped fiber A is less than 30% by weight, a desired napped fabric may not be obtained.

In particular, non-twisted yarn is preferable. When a strong twist is imparted like a strong twisted yarn, it is not preferred that crimps are difficult to decrease when wet. It should be noted that interlaced air processing and / or normal false twist crimping may be performed so that the number of entanglements is about 20 to 60 pieces / m.

Further, the single yarn fineness and the number of single yarns (number of filaments) of such other fibers are not particularly limited.

It is preferable to be within a range of ˜5 dtex (more preferably 0.5 to 2 dtex) and a single yarn number of 20 to 200 (more preferably 30 to 100).

本発明の立毛布帛は、例えば下記の製造方法によって容易に得ることができる。
まず、固有粘度が０．３０〜０．４３（オルソクロロフェノールを溶媒として３５℃で測定）の、５−ナトリウムスルホイソフタル酸が２．０〜４．５モル％共重合された変性ポリエステルと、固有粘度が１．０〜１．４（ｍ−クレゾールを溶媒として３０℃で測定）のポリアミドとを用いてサイドバイサイド型に溶融複合紡糸する。その際、ポリエステル成分の固有粘度が０．４３以下であることが特に重要である。ポリエステル成分の固有粘度が０．４３よりも大きいと、ポリエステル成分の粘度が増大するため、複合繊維の物性がポリエステル単独糸に近くなり、本発明が目的とする立毛布帛が得られないおそれがある。逆に、ポリエステル成分の固有粘度が０．３０よりも小さいと、溶融粘度が小さくなりすぎて製糸性が低下するとともに毛羽発生が多くなり、品質および生産性が低下するおそれがある。
The raised fabric of the present invention can be easily obtained, for example, by the following production method.
First, a modified polyester having an intrinsic viscosity of 0.30 to 0.43 (measured at 35 ° C. using orthochlorophenol as a solvent) and 2.0 to 4.5 mol% of 5-sodium sulfoisophthalic acid copolymerized; Using a polyamide having an intrinsic viscosity of 1.0 to 1.4 (measured at 30 ° C. using m-cresol as a solvent), melt composite spinning is performed in a side-by-side manner. At that time, it is particularly important that the intrinsic viscosity of the polyester component is 0.43 or less. If the intrinsic viscosity of the polyester component is larger than 0.43, the viscosity of the polyester component increases, so that the physical properties of the composite fiber are close to those of a single polyester yarn, and the napped fabric intended by the present invention may not be obtained. . On the other hand, if the intrinsic viscosity of the polyester component is less than 0.30, the melt viscosity becomes too small and the yarn-making property is lowered and the generation of fluff is increased, which may reduce the quality and productivity.
溶融紡糸の際に用いる紡糸口金としては、特開２０００−１４４５１８号公報の図１のような、高粘度側と低粘度側の吐出孔を分離し、かつ高粘度側吐出線速度を小さくした（吐出断面積を大きくした）紡糸口金が好適である。そして、高粘度側吐出孔に溶融ポリエステルを通過させ、低粘度側吐出孔に溶融ポリアミドを通過させ冷却固化させることが好ましい。その際、ポリエステル成分とポリアミド成分との重量比は、３０：７０〜７０：３０（より好ましくは４０：６０〜６０：４０）の範囲内であることが好ましい。 As the spinneret used for melt spinning, as shown in FIG. 1 of JP-A-2000-144518, the high-viscosity side and low-viscosity side discharge holes are separated and the high-viscosity side discharge linear velocity is reduced ( A spinneret having a large discharge cross-sectional area is preferred. Then, it is preferable that the molten polyester is passed through the high viscosity side discharge holes and the molten polyamide is passed through the low viscosity side discharge holes to be cooled and solidified. In that case, it is preferable that the weight ratio of a polyester component and a polyamide component exists in the range of 30: 70-70: 30 (more preferably 40: 60-60: 40).
また、溶融複合紡糸した後、一旦巻き取った後に延伸する別延方式を採用してもよいし、一旦巻き取らずに延伸熱処理を行う直延方式を採用してもよい。その際、紡糸・延伸条件としては、通常の条件でよい。例えば、直延方式の場合、１０００〜３５００ｍ／分程度で紡糸した後、連続して１００〜１５０℃の温度で延伸し巻き取る。延伸倍率は最終時に得られる複合繊維の切断伸度が１０〜６０％（好ましくは２０〜４５％）、切断強度が３．０〜４．７ｃＮ／ｄｔｅｘ程度となるよう、適宜選定すればよい。 Further, after the melt composite spinning, a separate stretching method in which the film is once wound and then stretched may be employed, or a direct stretching method in which a stretching heat treatment is performed without winding once may be employed. At that time, the spinning and drawing conditions may be normal conditions. For example, in the case of the direct extension method, after spinning at about 1000 to 3500 m / min, the film is continuously drawn and wound at a temperature of 100 to 150 ° C. The draw ratio may be appropriately selected so that the cut elongation of the composite fiber obtained at the end is 10 to 60% (preferably 20 to 45%) and the cut strength is about 3.0 to 4.7 cN / dtex.
次いで、かかる複合繊維糸条と必要に応じて他の繊維とを立毛部用糸条とし、地組織用繊維糸条とともに用いて、編織組織を有する地組織部と、ループパイル部とで構成されるパイル布帛を製編織した後、必要に応じループパイルの先端部をカットする。その際、立毛布帛の編織組織に制限はなく、例えば経パイル織物、緯パイル織物、シンカーパイル編物、ラッセルパイル編物、トリコットパイル編物などのループパイルをカットして得られたカットパイル布帛である。 Next, such a composite fiber yarn and other fibers as necessary are used as a napped portion yarn, and used together with the ground fabric fiber yarn, and is composed of a ground tissue portion having a knitted fabric structure and a loop pile portion. After the pile fabric is knitted and woven, the tip of the loop pile is cut as necessary. In that case, there is no restriction | limiting in the knitted fabric structure of a napped fabric, For example, it is a cut pile fabric obtained by cutting loop piles, such as a warp pile fabric, a weft pile fabric, a sinker pile knitted fabric, a Russell pile knitted fabric, a tricot pile knitted fabric.
次いで、該布帛を染色加工などの熱処理を施すことにより、前記複合繊維の捲縮を発現させる。
ここで、前記染色加工の温度としては１００〜１４０℃（より好ましくは１１０〜１３５℃）、時間としてはトップ温度のキープ時間が５〜４０分の範囲内であることが好ましい。かかる条件で、織編物に染色加工を施すことにより、前記複合繊維は、ポリエステル成分とポリアミド成分との熱収縮差により捲縮を発現する。その際、ポリエステル成分とポリアミド成分として、前述のポリマーを選定することにより、ポリアミド成分が捲縮の内側に位置する捲縮構造となる。
Next, the fabric is subjected to a heat treatment such as a dyeing process to develop crimps of the composite fiber.
Here, the temperature of the dyeing process is preferably 100 to 140 ° C. (more preferably 110 to 135 ° C.), and the time is preferably a top temperature keeping time within a range of 5 to 40 minutes. By applying a dyeing process to the woven or knitted fabric under such conditions, the composite fiber develops crimp due to a difference in thermal shrinkage between the polyester component and the polyamide component. At that time, by selecting the above-mentioned polymer as the polyester component and the polyamide component, a crimped structure is obtained in which the polyamide component is located inside the crimp.
染色加工が施された織編物には、通常、乾熱ファイナルセットが施される。その際、乾熱ファイナルセットの温度としては１２０〜２００℃（より好ましくは１４０〜１８０℃）、時間としては１〜３分の範囲内であることが好ましい。かかる、乾熱ファイナルセットの温度が１２０℃よりも低いと、染色加工時に発生したシワが残り易く、また、仕上がり製品の寸法安定性が悪くなるおそれがある。逆に、該乾熱ファイナルセットの温度が２００℃よりも高いと、染色加工の際に発現した複合繊維の捲縮が低下したり、繊維が硬化し生地の風合いが硬くなるおそれがある。 A dry heat final set is usually applied to the woven or knitted fabric subjected to the dyeing process. At that time, the temperature of the dry heat final set is preferably 120 to 200 ° C. (more preferably 140 to 180 ° C.), and the time is preferably within a range of 1 to 3 minutes. When the temperature of the dry heat final set is lower than 120 ° C., wrinkles generated during the dyeing process are likely to remain, and the dimensional stability of the finished product may be deteriorated. On the other hand, if the temperature of the dry heat final set is higher than 200 ° C., the crimp of the composite fiber developed during the dyeing process may be reduced, or the fiber may be cured and the texture of the fabric may be hardened.
また、本発明の立毛布帛に吸水加工を施すことが好ましく、これにより汗の拡散速度を上げベトツキ感を抑制すると共に、捲縮繊維Ａの捲縮変化速度を上げ、立毛高さ変化の応答性が速くなり好ましい。 Further, it is preferable that the napped fabric of the present invention is subjected to a water absorption process, thereby increasing the sweat diffusion rate and suppressing the stickiness, and increasing the crimp change rate of the crimped fiber A, thereby responding to changes in napped height. Is faster and preferable.
吸水加工を施す方法は特に限定しないが、例えば染色時に染液に吸汗加工剤を混合する浴中加工法やファイナルセット前に織編物を吸汗加工液中にディッピングしマングルで絞った後、連続的にファイナルセットを行う方法、またはグラビヤコーティング法、スクリーンプリント法といった塗布による加工方法等が挙げられる。 There is no particular limitation on the method of performing water absorption processing, but for example, a processing method in a bath in which a sweat absorbing agent is mixed with the dyeing solution during dyeing, or after woven or knitted fabric is dipped into the sweat absorbing processing solution and squeezed with a mangle before final setting And a final setting method, or a processing method by coating such as a gravure coating method or a screen printing method.
かくして得られた立毛布帛において、立毛部に含まれる捲縮繊維Ａの捲縮率が、湿潤時に可逆的に低下するため、捲縮繊維Ａからなる立毛糸の立毛高さが大きくなる。 In the napped fabric thus obtained, the crimped rate of the crimped fiber A contained in the napped portion is reversibly lowered when wet, so that the napped height of the napped yarn made of the crimped fiber A is increased.
ここで、下記式で算出する立毛高さ変化率が５％以上（より好ましくは５０〜１００％）であることが好ましい。
立毛高さ変化率（％）＝（（ＬＷ−ＬＤ）／ＬＤ）×１００
Here, it is preferable that the nap height change rate calculated by the following formula is 5% or more (more preferably 50 to 100%).
Napped height change rate (%) = ((LW−LD) / LD) × 100
ただし、ＬＤとは、立毛布帛を温度２０℃、湿度６５％ＲＨ環境下に２４時間放置した後の状態で測定した立毛高さであり、一方ＬＷとは、立毛部表面に水を１ｃｃ滴下した後、１分経過後の最大立毛高さである。 However, LD is the napped height measured in a state where the napped fabric is left in a temperature of 20 ° C. and a humidity of 65% RH for 24 hours, while LW is 1 cc of water dropped on the napped surface. The maximum napped height after 1 minute has elapsed.
このように、湿潤時に捲縮繊維Ａの捲縮率が低下し、捲縮繊維Ａからなる立毛糸の立毛高さが大きくなることにより、立毛布帛の通気性は湿潤時に向上する。かかる通気性の変化量としては、湿潤時における立毛布帛の通気性が、乾燥時よりも１０％以上（より好ましくは１５〜５０％）高くなることが好ましい。 As described above, the crimp rate of the crimped fiber A is lowered when wet, and the raised height of the raised yarn made of the crimped fiber A is increased, so that the air permeability of the raised fabric is improved when wet. As the amount of change in air permeability, it is preferable that the air permeability of the napped fabric when wet is 10% or more (more preferably 15 to 50%) higher than when dry.
