Description

【0001】
【発明の属する技術分野】
本発明は、ブラックフォーマル用布帛に関するものであり、より詳細には吸湿性、発色性、制電性および遮熱性に優れたブラックフォーマル用布帛に関する。
【0002】
【従来の技術】
ファッション衣料分野において、特開平11−286843号公報に提案されているようにセルロース系繊維を芯糸、ポリエステル系重合体繊維を鞘糸に用いた複合糸はカジュアル用としてもてはやされてきたが、染色性及び発色性、強度の点からブラックフォーマルの用途には用いられていなかった。
一方、ブラックフォーマル用途では、二種類のポリエステル重合体繊維を芯糸・鞘糸に用いた複合糸が主流で、ハリ・コシ感には優れているが蒸れ感が大きく、また、帯電性が大きい為帯電防止剤等の付与が必要であった。
【0003】
【発明が解決しようとする課題】
本発明の目的は、吸湿性、発色性、制電性および遮熱性に優れたブラックフォーマル用布帛を提供することにある。
【0004】
【課題を解決するための手段】
すなわち、本発明は、鞘糸が繊維表面が不規則な凹凸ランダム表面を形成しているポリエステル系重合体繊維、芯糸がキュプラ繊維からなる芯鞘複合糸を、単独または他のポリエステル系重合体繊維と合わせて、製編織してなるブラックフォーマル用布帛であって、キュプラ繊維が該布帛に対して20%以上占めているブラックフォーマル用布帛である。
【0005】
【発明の実施の形態】
本発明のブラックフォーマル用布帛を構成する芯鞘複合糸は、鞘糸にポリエステル系繊維を用いる。該ポリエステル系繊維を構成するポリマーは、ポリエチレンテレフタレート、ポリブチレンテレフタレート等特に限定されないが、シリカ系無機微粒子の分散性の点からポリエチレンテレフタレートを用いることが好ましい。
なお該ポリエステル系繊維は、必要に応じて他のジカルボン酸成分、オキシカルボン酸成分、他のジオール成分の1種または2種以上を共重合単位として有していてもよい。
また、該ポリエステル系繊維は繊維表面にが不規則な凹凸ランダム表面を形成していることにより、布帛とした際に優れた発色性が奏される。本発明にいう不規則な凹凸ランダム表面については、特公昭59−24233号公報で規定されている通りである。
本発明に用いるポリエステル系重合体繊維は、紡糸時に平均一次粒子径が100nm以下、より好ましくは60nm以下のシリカ系無機微粒子を0.2〜3%添加し、得られた繊維を布帛とした後、アルカリ減量処理により形成させることができる。シリカ系無機微粒子の平均一次粒子系が大き過ぎると原糸の紡糸時及び撚糸加工時等に糸切れ等の操業性に問題が生じる場合があり好ましくない。また、シリカ系無機微粒子の添加量が0.2%より少ない場合はアルカリ減量後の繊維表面の凹凸が少なくなり染色後の発色が悪くなる為好ましくない。3%より多い場合は、原糸の紡糸時及び撚糸加工時等に糸切れ等の操業性に問題が生じる事があり好ましくない。
鞘糸を構成するポリエステル系重合体繊維の単糸繊度は、5dtex以下が好ましく、より好ましくは1〜3dtexである。また、フィラメント数は10〜80本が好ましく、より好ましくは20〜40本である。単糸繊度が5detxを超えると風合を満足できず、また、混繊し難いなど操業性に問題が生じる事があり好ましくない。フィラメント数が少なすぎると布帛のハリコシが無くなり、またドライ感を得られない場合がある。また、該ポリエステル系重合体繊維の全繊度についても特に限定されない。
【0006】
該ポリエステル系重合体繊維の断面形状については、丸型、三角型、長方形型、中空型等特に限定はなく、目的に応じて設定すればよい。なお、本発明の効果を損なわない範囲で通常用いられる添加剤を添加してもよい。
【0007】
本発明に用いる芯鞘複合糸を構成する芯糸は、キュプラ繊維を用いることが重要である。芯糸にキュプラ繊維を使用することにより、ポリエステル系重合体繊維のみのものには及ばないものの、他のセルロース系繊維のレーヨンなどを用いたものよりもハリ・コシ感が出、強度も得られる。
その単糸繊度は0.8〜5dtexが好ましく、より好ましくは1〜3dtexである。また、全繊度は50〜160dtexが好ましく、より好ましくは60〜120dtexである。全繊度が50dtex未満の場合は、ポリエステル系重合体繊維と混繊し撚りをかけた際、複合糸の断面構造が芯鞘構造になり難い場合がある。
【0008】
本発明に用いる芯鞘複合糸は、鞘糸となるポリエステル系重合体繊維と芯糸となるキュプラ繊維を交絡させて得ることができる。交絡方法は特に限定されないが、容易に芯部にキュプラ繊維を偏在させることが出来る点からエアー交絡を採用することが好ましい。
ポリエステル系重合体繊維とキュプラ繊維をエアー混繊することで複合し、撚糸することで、芯部にキュプラ繊維が多く偏在し、鞘部にポリエステル系重合体繊維が芯部を包みこむような形態をとる糸が得られる。その為、この複合糸を用い製編織した布帛は、肌との接触面がポリエステル系繊維となるため、ドライ感を保持した上で、キュプラ繊維の吸湿性を兼ね備えた布帛となる。
【0009】
交絡する際に、ポリエステル系重合体繊維とキュプラ繊維の複合比率は30:70〜80:20が好ましく、より好ましくは、40:60〜60:40である。
ポリエステル系重合体繊維とキュプラ繊維の複合比率が80:20よりポリエステル系重合体繊維の割合が多いと、ポリエステル系重合体繊維単独の布帛と吸湿性の点で明確に差が出ないなど好ましくない。また、ポリエステル系重合体繊維とキュプラ繊維の複合比率が30:70よりキュプラ繊維の割合が多いと、布帛形成仕上がり後、皺が出来易い、ブラックフォーマルに要求される風合及び発色が得られないなど問題が生じ好ましくない。
【0010】
本発明のブラックフォーマル用布帛は、該芯鞘複合糸を、単独または他のポリエステル系重合体繊維と合わせて、製編織して得ることができ、その製編組織については限定されないが、二重織り、バックサテンが好ましい。
なお、本発明の布帛を得る際、キュプラ繊維が全布帛に対して20%以上占めるように製編織することが極めて重要であり、好ましくは40〜60%である。キュプラ繊維の占める割合が20%未満であると、従来のポリエステル系重合体繊維100%のブラックフォーマル用布帛との吸湿性での有意差が出ない等好ましくない。
【0011】
ついで、該芯鞘複合糸を用いて得られた布帛を、精練リラックス後、中間セットし、その後、約10%程度アルカリ減量処理する事で、ポリエステル系重合体繊維の繊維表面が不規則な凹凸ランダム表面に形成された布帛が得られる。なお、同じセルロース系繊維のレーヨンなどをキュプラの代わりに用いているとアルカリ減量工程を通過する事で強度劣化を生じ、男性用アウターには使用できない。
【0012】
得られた布帛を染色する際は、より濃色に仕上げ、発色性に優れた布帛を得ることができる点から、分散染料と反応染料を用いて芯糸および鞘糸をそれぞれ染色することが望ましい。例えば、一浴二段染色で、最初の一段で反応染料にてキュプラ繊維側を90℃で染め、次の二段目にてポリエステル系重合体繊維を分散染料にて130℃染色する。染色後180℃の仕上げセットをした後、濃染加工剤をPad−Cureにより付着させ最終仕上がり品が得ることができる。最終仕上がり後の布帛のL*値は、11以下が好ましく、より好ましくは8〜10である。
【0013】
通常ブラックフォーマルは、ドライクリーニングが主流であるが、本発明の布帛を用いてなるブラックフォーマルは水系洗濯も可能であり、優れた耐洗濯性を有する。
【0014】
ついで得られた該ブラックフォーマル用布帛を、対照をポリエチレンテレフタレートのみのブラックフォーマル用布帛として、太陽光を想定したレフランプ照射時の昇温の比較を実施すると、キュプラ繊維が保湿している水分の蒸発潜熱の影響で、ポリエチレンテレフタレートのみの布帛に比べ昇温スピードが遅い(遮熱性が高い)結果を示す。
【0015】

BACKGROUND OF THE INVENTION
The present invention relates to a fabric for black formal, and more particularly to a fabric for black formal excellent in hygroscopicity, color development, antistatic properties and heat shielding properties.
[0002]
[Prior art]
In the fashion apparel field, as proposed in Japanese Patent Laid-Open No. 11-286843, composite yarns using cellulosic fibers as core yarns and polyester polymer fibers as sheath yarns have been used for casual purposes. It was not used for black formal applications in terms of colorability, color developability and strength.
On the other hand, in black formal applications, composite yarns using two types of polyester polymer fibers as the core yarn and sheath yarn are the mainstream, and they are excellent in firmness and firmness but have a great feeling of stuffiness and a large chargeability. Therefore, it was necessary to apply an antistatic agent or the like.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a fabric for black formal that is excellent in hygroscopicity, coloring property, antistatic property and heat shielding property.
[0004]
[Means for Solving the Problems]
That is, the present invention relates to a polyester-based polymer fiber in which the sheath yarn forms an irregular random surface with irregular fiber surfaces, and a core-sheath composite yarn in which the core yarn is made of cupra fiber, either alone or in other polyester polymers. A black formal fabric formed by weaving and weaving together with fibers, wherein the cupra fibers occupy 20% or more of the fabric.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The core-sheath composite yarn constituting the black formal fabric of the present invention uses polyester fibers for the sheath yarn. The polymer constituting the polyester fiber is not particularly limited, such as polyethylene terephthalate and polybutylene terephthalate, but polyethylene terephthalate is preferably used from the viewpoint of dispersibility of silica-based inorganic fine particles.
In addition, this polyester fiber may have 1 type, or 2 or more types of another dicarboxylic acid component, an oxycarboxylic acid component, and another diol component as a copolymerization unit as needed.
In addition, since the polyester fiber has an irregular irregular surface on the fiber surface, excellent color developability is achieved when it is made into a fabric. The irregular uneven random surface referred to in the present invention is as defined in JP-B-59-24233.
The polyester polymer fiber used in the present invention is obtained by adding 0.2 to 3% of silica-based inorganic fine particles having an average primary particle size of 100 nm or less, more preferably 60 nm or less during spinning, and using the resulting fiber as a fabric. It can be formed by an alkali weight loss treatment. If the average primary particle size of the silica-based inorganic fine particles is too large, there may be a problem in operability such as yarn breakage during spinning of the raw yarn and twisting processing, which is not preferable. In addition, when the amount of silica-based inorganic fine particles added is less than 0.2%, the unevenness of the fiber surface after the alkali reduction is reduced, and the color development after dyeing is not preferable. If it is more than 3%, there is a problem in operability such as yarn breakage at the time of spinning the raw yarn and twisting processing, which is not preferable.
The single yarn fineness of the polyester polymer fibers constituting the sheath yarn is preferably 5 dtex or less, more preferably 1 to 3 dtex. Moreover, the number of filaments is preferably 10 to 80, more preferably 20 to 40. If the single yarn fineness exceeds 5 detex, the texture cannot be satisfied, and there is a problem in operability such as difficulty in mixing, which is not preferable. If the number of filaments is too small, there will be no fabric tension and a dry feeling may not be obtained. Further, the total fineness of the polyester polymer fiber is not particularly limited.
[0006]
The cross-sectional shape of the polyester polymer fiber is not particularly limited, such as a round shape, a triangular shape, a rectangular shape, or a hollow shape, and may be set according to the purpose. In addition, you may add the additive normally used in the range which does not impair the effect of this invention.
[0007]
It is important to use cupra fibers as the core yarn constituting the core-sheath composite yarn used in the present invention. By using cupra fiber as the core yarn, it does not reach the polyester polymer fiber alone, but it feels firmer and firmer than those using other cellulosic fiber rayon and provides strength. .
The single yarn fineness is preferably 0.8 to 5 dtex, more preferably 1 to 3 dtex. The total fineness is preferably 50 to 160 dtex, more preferably 60 to 120 dtex. When the total fineness is less than 50 dtex, the cross-sectional structure of the composite yarn may not easily become a core-sheath structure when mixed with the polyester polymer fiber and twisted.
[0008]
The core-sheath composite yarn used in the present invention can be obtained by interlacing a polyester polymer fiber serving as a sheath yarn and a cupra fiber serving as a core yarn. The entanglement method is not particularly limited, but it is preferable to adopt air entanglement from the viewpoint that the cupra fibers can be easily unevenly distributed in the core.
Polyester polymer fiber and cupra fiber are mixed by air mixing and twisted, so that many cupra fibers are unevenly distributed in the core, and polyester polymer fiber wraps around the core in the sheath A yarn is obtained. Therefore, the fabric knitted and woven using this composite yarn becomes a fabric having a hygroscopic property of the cupra fiber while maintaining a dry feeling because the contact surface with the skin is a polyester fiber.
[0009]
When entangled, the composite ratio of the polyester polymer fiber and the cupra fiber is preferably 30:70 to 80:20, more preferably 40:60 to 60:40.
When the ratio of the polyester polymer fiber to the polyester polymer fiber is more than 80:20, the polyester polymer fiber and the cupra fiber are not preferable because the polyester polymer fiber alone has no difference in hygroscopicity. . In addition, when the ratio of the polyester polymer fiber and the cupra fiber is larger than 30:70, the texture and color required for the black formal cannot be obtained after finishing the formation of the fabric. Such a problem is not preferable.
[0010]
The fabric for black formal of the present invention can be obtained by knitting or weaving the core-sheath composite yarn alone or in combination with other polyester polymer fibers, and the knitting structure is not limited. Woven and back satin are preferred.
In addition, when obtaining the fabric of this invention, it is very important to fabricate so that a cupra fiber may occupy 20% or more with respect to all the fabrics, Preferably it is 40 to 60%. If the proportion of the cupra fibers is less than 20%, it is not preferable because there is no significant difference in hygroscopicity from a conventional 100% polyester polymer fiber 100% black formal fabric.
[0011]
Next, the fabric obtained by using the core-sheath composite yarn is subjected to relaxation by scouring, and then intermediately set, and then subjected to an alkali weight reduction treatment of about 10%, whereby the fiber surface of the polyester polymer fiber is irregularly uneven. A fabric formed on a random surface is obtained. If the same cellulosic fiber rayon or the like is used in place of cupra, strength deterioration occurs due to passing through the alkali weight loss process, and it cannot be used for a male outer.
[0012]
When dyeing the obtained fabric, it is desirable to dye the core yarn and the sheath yarn using a disperse dye and a reactive dye from the standpoint of obtaining a fabric having a darker color and excellent color developability. . For example, in one bath two-stage dyeing, the cupra fiber side is dyed at 90 ° C. with the reactive dye in the first one stage, and the polyester polymer fiber is dyed at 130 ° C. with the disperse dye in the next second stage. After dyeing, after finishing finishing at 180 ° C., a deep dyeing agent is attached by Pad-Cure to obtain a final finished product. The L * value of the fabric after final finishing is preferably 11 or less, more preferably 8 to 10.
[0013]
Usually, black formal is mainly used for dry cleaning. However, black formal using the fabric of the present invention can be washed in water and has excellent washing resistance.
[0014]
Then, when the black formal fabric obtained was compared with a black formal fabric made of only polyethylene terephthalate, and the temperature rise during the reflex lamp irradiation was assumed assuming sunlight, evaporation of the moisture retained by the cupra fiber was performed. Due to the influence of latent heat, the results show that the heating rate is slower (higher heat shielding properties) than the fabric made of polyethylene terephthalate alone.
[0015]
