Description
本発明は、総繊度、単糸繊度、収縮率が異なる、少なくとも２成分糸から構成されるポリエステル極細混繊糸に関するものである。 The present invention relates to a polyester ultrafine mixed yarn composed of at least two-component yarns having different total fineness, single yarn fineness, and shrinkage rate.
従来ポリエステル繊維は優れた強度と取り扱いの利便性から衣料用繊維として広く利用されてきた。合成繊維としての優れた機能のバランスから、天然繊維の様な風合いやドレープ性を追求する製造技術検討は多い。（特許文献１、２、３）。
中でも合成繊維特有の単調な外観を改善する為の杢調外観、梳毛調外観付与と並んで、合成繊維特有の薄く硬い手触りを改善すべく様々な形態付与の方法が提案されている。
Conventionally, polyester fibers have been widely used as clothing fibers because of their excellent strength and convenience in handling. From the balance of excellent functions as a synthetic fiber, there are many manufacturing technology studies that pursue the texture and drapeability of natural fibers. (Patent Documents 1, 2, and 3).
Above all, various methods for imparting various forms have been proposed to improve the thin and hard hand unique to synthetic fibers, along with imparting a tonal appearance and an eyelash appearance to improve the monotonous appearance unique to synthetic fibers.
特にポリエステル繊維は優れた機械的強度の為に織機上で高速製織されるが、他方仕上がりでの生地のフクラミやドレープ性といった柔らかさという相反する性質が求められている。これを両立させる方法として、例えば特開平９−２４１９３８号公報、特開平１１−２７９８７９号公報、特開２００３−３３６１３６号公報では、糸の熱収縮差を利用して製織後に生地にフクラミを与えるという手法が紹介されている。 In particular, polyester fibers are woven at high speed on a loom due to their excellent mechanical strength. On the other hand, there is a demand for contradictory properties such as softness and drape of the finished fabric. As a method for making this compatible, for example, in Japanese Patent Application Laid-Open Nos. 9-24138, 11-279879, and 2003-336136, it is said that the fabric is woven by using the heat shrinkage difference of the yarn after weaving. Techniques are introduced.
確かにこの方法により嵩高で、ソフトで柔軟な風合いが得られるため、織編物用途を始めとして、広く用いられるようになってきている。しかしながら更に柔軟性の高いソフトな布帛を得るためには、単糸繊度の細い原糸を使用せざるを得ず、そのため原糸強度ひいては布帛の強度が低下するという問題があった。 Certainly, this method can provide a bulky, soft and flexible texture, so that it is widely used for woven and knitted fabrics. However, in order to obtain a soft fabric with higher flexibility, it is necessary to use a raw yarn having a fine single yarn fineness, which causes a problem that the strength of the raw yarn and thus the strength of the fabric is lowered.
このため極細化可能繊維、例えば分割型繊維、海島繊維の海成分を溶解して極細化するという方法が開示されているが（特許文献８、９）により可能であるが煩雑な手段となりコストが高いという問題があり、通常紡糸極細繊維からなる混繊糸の開発が強く望まれていた。 For this reason, a method of dissolving ultrafine fibers, for example, split-type fibers and sea-island fibers to make them ultrafine is disclosed (Patent Documents 8 and 9). There has been a problem that it is expensive, and there has been a strong demand for the development of blended yarn made of usually spun ultrafine fibers.
本発明は、上記のような問題点を解決し、極細繊度でありながら高強力を有し、かつ嵩高で、ソフトで柔軟な風合いをもつ布帛とすることができるポリエステル極細混繊糸を提供することを課題とするものである。 The present invention provides a polyester ultrafine mixed yarn that solves the above-described problems and that can be made into a fabric having a high strength and a bulky, soft and soft texture while having an ultrafineness. This is a problem.
本発明者らは、上記課題を解決すべく鋭意検討を重ねた結果得られたもので、

ｂ）ポリエステル糸Ｂが、総繊度（Ｂ１）１０〜２０ｄｔｅｘ、単糸繊度（Ｂ２）０．８０〜２．０ｄｔｅｘ、沸騰水中の収縮率（Ｂ３）１０〜２５％であること。
ｃ）ポリエステル糸Ａとポリエステル糸Ｂとが交絡を有し、交絡数が６０〜１６０ケ／ｍであること。

が提供される。
The present inventors were obtained as a result of intensive studies to solve the above problems,
That is, according to the present invention,

In the mixed yarn, the polyester mixed yarn preferably has an intrinsic viscosity [η] B of the polyester yarn B higher than the intrinsic viscosity [η] A of the polyester yarn A,
Is provided.
本発明の混繊糸は収縮させることにより芯部と鞘部の２層構造糸となり、特定の総繊度、極細繊度を有するポリエステル糸が鞘部を構成するので、極細繊維のソフト性、風合いを有し且つ高強度の布帛となる。 The mixed yarn of the present invention is made into a two-layer structure yarn of a core portion and a sheath portion by shrinking, and a polyester yarn having a specific total fineness and extra fineness constitutes the sheath portion, so that the softness and texture of the extra fine fibers are improved. It has a high strength fabric.
本発明で用いられるポリエステルは、エチレンテレフタレートを主たる繰り返し単位とするポリエステルを対象とするものであり、好ましくは７０モル％、より好ましくは８０モル％以上がエチレンテレフタレート単位とするポリエステルである。 The polyester used in the present invention is intended for a polyester having ethylene terephthalate as a main repeating unit, and is preferably 70 mol%, more preferably 80 mol% or more of an ethylene terephthalate unit.
本発明のポリエステル混繊糸の染色性、抗ピル性、熱収縮特性等を改善するために、ポリエステルに少量（通常、１５モル％以下、好ましくは１０モル％以下）の第３成分を共重合したものであってもよい。また、他種ポリマーを少量（通常、ポリエステルに対して１０重量％以下）混合してもよい。更に、制電剤、艶消剤、紫外線吸収剤、染色性改良剤の添加剤を配合したものであってもよい。また、リサイクル可能なポリマーであることが好ましい。 In order to improve the dyeability, anti-pill property, heat shrinkage characteristics, etc. of the polyester blended yarn of the present invention, a small amount (usually 15 mol% or less, preferably 10 mol% or less) of the third component is copolymerized with the polyester. It may be what you did. Moreover, you may mix a small amount (usually 10 weight% or less with respect to polyester) other types of polymers. Further, an additive such as an antistatic agent, a matting agent, an ultraviolet absorber, and a dyeability improving agent may be blended. Moreover, it is preferable that it is a recyclable polymer.
本発明のポリエステル混繊糸の一方成分であるポリエステル糸Ａとしては、総繊度が１５〜３０ｄｔｅｘである必要があり、好ましくは１７〜２５ｄｔｅｘである。総繊度が１５ｄｔｅｘ未満であれば混繊糸の強度が低下し、３０ｄｔｅｘを超える場合は柔軟性低下し布帛が硬くなる。又単糸繊度は０．１５〜０．５０ｄｔｅｘである必要があり、０．２０〜０．４０ｄｔｅｘであることが好ましい。０．１５ｄｔｅｘ未満であれば強度が低下し、０．５０ｄｔｅｘを超える場合は極細繊維の風合い、柔軟性が低下し好ましくない。更に沸騰水中の収縮率が３〜１０％であることが必要であり、好ましくは３〜５％である。沸騰水中の収縮率が３％未満であれば布帛とした時緻密感が得られず好ましくなく、１０％を超える場合は混繊糸の嵩高性、膨らみ感が得られず好ましくない。固有粘度［η］Ａはポリエステル糸Ｂの固有粘度［η］Ｂより低いことが好ましく、０．７５未満であることが好ましい。より好ましくは０．４〜０．７０である。固有粘度［η］Ａが０．７５以上であれば混繊糸、それを製編織して得られる布帛の柔軟性が低下し好ましくない。 The polyester yarn A which is one component of the polyester blended yarn of the present invention needs to have a total fineness of 15 to 30 dtex, preferably 17 to 25 dtex. If the total fineness is less than 15 dtex, the strength of the mixed yarn is lowered, and if it exceeds 30 dtex, the flexibility is lowered and the fabric becomes hard. The single yarn fineness needs to be 0.15 to 0.50 dtex, preferably 0.20 to 0.40 dtex. If it is less than 0.15 dtex, the strength is lowered, and if it exceeds 0.50 dtex, the texture and flexibility of the ultrafine fiber are lowered, which is not preferable. Furthermore, the shrinkage ratio in boiling water is required to be 3 to 10%, preferably 3 to 5%. If the shrinkage in boiling water is less than 3%, it is not preferable because a dense feeling cannot be obtained when it is made into a fabric, and if it exceeds 10%, the bulkiness and swell of the mixed yarn cannot be obtained. The intrinsic viscosity [η] A is preferably lower than the intrinsic viscosity [η] B of the polyester yarn B, and is preferably less than 0.75. More preferably, it is 0.4-0.70. If the intrinsic viscosity [η] A is 0.75 or more, the flexibility of the blended yarn and the fabric obtained by weaving and knitting it are not preferred.
本発明のポリエステル混繊糸のもう一方の成分であるポリエステル糸Ｂにおいては、総繊度が１０〜２０ｄｔｅｘであることが必要であり、好ましくは１２〜１８ｄｔｅｘである。総繊度が１０ｄｔｅｘ未満であると強度が低下し、２０ｄｔｅｘを超える場合は混繊糸ひいては布帛のソフト性、柔軟性が低下し好ましくない。又単糸繊度は０．８〜２．０ｄｔｅｘである必要があり、好ましくは１．０〜１．５ｄｔｅｘである。０．８ｄｔｅｘ未満であれば混繊糸の強度が低下し、２．０ｄｔｅｘを超える場合は混繊糸ひいては布帛のソフト性、柔軟性が低下し好ましくない。又ポリエステル糸Ｂの固有粘度［η］Ｂは０．７５〜１．００であることが必要である。好ましくは０．７５〜０．９０である。固有粘度［η］Ｂが０．７５未満であれば強度が低下し、１．０を超える場合は重合粘度が高く、製糸性が悪くなり好ましくない。又沸騰水収縮率が１０〜２５％であることが必要である。好ましくは１２〜１８％である。収縮率が１０％未満であれば布帛にした後染色等の熱処理により収縮が少ないため嵩高性が発現せず膨らみ感のない布帛となる。２５％を超える場合は収縮しすぎるため布帛が硬くなり風合いが低下する。沸騰水収縮率を調整するためには公知の方法を用いることができるが、例えば弛緩熱処理して延伸倍率を調整するなどの方法を用いることができる。 In the polyester yarn B which is the other component of the polyester mixed yarn of the present invention, the total fineness needs to be 10 to 20 dtex, preferably 12 to 18 dtex. If the total fineness is less than 10 dtex, the strength is lowered, and if it exceeds 20 dtex, the mixed yarn and thus the softness and flexibility of the fabric are lowered, which is not preferable. The single yarn fineness needs to be 0.8 to 2.0 dtex, and preferably 1.0 to 1.5 dtex. If it is less than 0.8 dtex, the strength of the blended yarn is lowered, and if it exceeds 2.0 dtex, the blended yarn and thus the softness and flexibility of the fabric are lowered. Further, the intrinsic viscosity [η] B of the polyester yarn B needs to be 0.75 to 1.00. Preferably it is 0.75-0.90. If the intrinsic viscosity [η] B is less than 0.75, the strength is lowered, and if it exceeds 1.0, the polymerization viscosity is high, and the yarn-making property is deteriorated. Further, the boiling water shrinkage is required to be 10 to 25%. Preferably it is 12 to 18%. If the shrinkage rate is less than 10%, the fabric is made into a fabric having no bulkiness due to less shrinkage due to heat treatment such as dyeing after being made into a fabric. If it exceeds 25%, the fabric shrinks too much and the fabric becomes hard and the texture is lowered. A known method can be used to adjust the boiling water shrinkage. For example, a method of adjusting the draw ratio by relaxing heat treatment can be used.
本発明のポリエステル混繊糸の製造方法としては、ポリエチレンテレフタレートを常法により溶融し、２，７００〜２，９００ｍ／分の紡糸速度で紡糸して、単糸繊度が０．１５〜０．５０ｄｔｅｘのポリエステル延伸糸（ポリエステル糸Ａ）とし、一方、固有粘度［η］Ｂが０．７５〜１．００であるポリエチレンテレフタレートを常法により溶融し、８００〜９００ｍ／分の紡糸速度で紡糸して、単糸繊度が０．８０〜２．０ｄｔｅｘのポリエステル未延伸糸（ポリエステル糸Ｂ）とし、両者を図１に示す公知の混繊装置でポリエステル混繊糸とすることにより得られる。 As a method for producing the polyester blended yarn of the present invention, polyethylene terephthalate is melted by a conventional method and spun at a spinning speed of 2,700-2,900 m / min, and the single yarn fineness is 0.15-0.50 dtex.

After being supplied at a speed of / min, entangled by compressed air and interlaced, it is wound on a package 6.
上記した本発明の構成、方法により製造したポリエステル混繊糸は極細繊度で構成され且つ４．０ｃＮ／ｄｔｅｘ以上の強度を有するものとなり、公知の製編織機により布帛とし、その後に染色等の沸騰水処理工程を通過することにより、ポリエステル糸Ｂが収縮し芯部を、０．１５〜０．５０ｄｔｅｘの単糸繊度からなるポリエステル糸Ａが外層部を構成する構造を形成し、極細糸の風合い、柔軟性を有し且つ嵩高性で強度の高い布帛とすることができる。 The polyester blended yarn produced by the above-described constitution and method of the present invention has a fineness and has a strength of 4.0 cN / dtex or more, and is made into a fabric by a known weaving and weaving machine, and then boiled for dyeing and the like. By passing through the water treatment step, the polyester yarn B contracts to form a core portion, and the polyester yarn A having a single yarn fineness of 0.15 to 0.50 dtex forms the outer layer portion. , A fabric having flexibility, bulkiness and high strength can be obtained.

得られた混繊糸を経糸、緯糸に用いて羽二重に製織し、常法に従って精練、熱セット、アルカリ減量加工（減量率１５％）染色を施して無地の染め織物を得た。染色工程で沸騰水処理することによりポリエステル糸Ｂが収縮し芯部を、ポリエステル糸Ａが鞘部を構成した。
In this step, the polyester yarn B ′ became a polyester yarn B having a total fineness of 15 dtex / 12 filament (single fiber fineness: 1.25 dtex). The intrinsic viscosity [η] B was 0.80 and the boiling water shrinkage B3 was 16%.
During the production of the polyester blended yarn, no contact of the yarn with the slit heater 5 was observed, and the yarn breakage was only 2.9%. The strength of the obtained mixed yarn was 4.6 cN / dtex.
The resulting blended yarn was used for warp and weft to be double woven, and subjected to scouring, heat setting, and alkali weight loss processing (weight loss rate 15%) in accordance with a conventional method to obtain a plain dyed fabric. By performing boiling water treatment in the dyeing process, the polyester yarn B contracted to form a core portion, and the polyester yarn A constituted a sheath portion.
