本発明は、羽毛の吹き出し抑制（ダウンプルーフ性）に富み、かつ縫製後の縫目外観に優れた羽毛製品を得ることが可能な羽毛製品用縫製糸、および該縫製糸を用いてなる羽毛製品に関する。 The present invention relates to a sewing thread for a feather product that is rich in feather blowing suppression (down-proof property) and that can provide a feather product excellent in stitch appearance after sewing, and a feather product that uses the sewing thread. About.
従来、ジャケット、ジャンパー、ブルゾン等の防寒具などにおいて、内部に羽毛を充填することで断熱効果の高い空気層を効率的に形成し、保温効果を高めた羽毛製品が用いられている。また、かかる羽毛製品において、羽毛の吹き出しを抑制するには表地と羽毛との間および裏地と羽毛との間に袋状に縫ったダウンパックと呼ばれる中生地を設けることが一般的である。しかしながら、ダウンパックを用いた場合、工程が煩雑になるだけでなく、羽毛製品の重量が重くなるという問題があった。このため、近年では、ダウンパックを省略することも行われている。 Conventionally, in cold protection equipment such as jackets, jumpers, blousons, and the like, feather products have been used in which an air layer having a high heat insulation effect is efficiently formed by filling the inside with feathers, and the heat retention effect is enhanced. Moreover, in such a feather product, in order to suppress the blowing of feathers, it is common to provide an inner fabric called a down pack that is sewn in a bag shape between the outer material and the feathers and between the lining material and the feathers. However, when the downpack is used, there is a problem that not only the process becomes complicated, but also the weight of the feather product becomes heavy. For this reason, in recent years, the downpack has been omitted.
一方、羽毛製品用縫製糸としては、マルチフィラメントを用いたものや紡績糸を用いたものなど種々の縫製糸が提案されている（例えば、特許文献１、特許文献２参照）。
しかしながら、マルチフィラメントを用いた縫製糸では、ミシン針が貫通した後の針穴をふさぐ効果に乏しく羽毛が吹き出すおそれがあった。一方、紡績糸を用いた縫製糸では、縫製糸が表地に露出した場合、表地を構成するマルチフィラメントと紡績糸との統一感が乏しく縫製後の縫目外観が劣るという問題があった。
On the other hand, as sewing threads for feather products, various sewing threads such as those using multifilaments and spun yarns have been proposed (see, for example, Patent Document 1 and Patent Document 2).
However, the sewing thread using the multifilament has a poor effect of closing the needle hole after the sewing needle has penetrated, and there is a possibility that feathers may blow out. On the other hand, in the case of the sewing yarn using the spun yarn, when the sewing yarn is exposed on the outer surface, there is a problem that the sense of unity between the multifilament and the spun yarn constituting the outer surface is poor and the stitch appearance after sewing is inferior.
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、羽毛の吹き出し抑制（ダウンプルーフ性）に富み、かつ縫製後の縫目外観に優れた羽毛製品を得ることが可能な羽毛製品用縫製糸、および該縫製糸を用いてなる羽毛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 its object is to provide a feather product that is rich in feather blowout suppression (down-proof property) and has an excellent seam appearance after sewing. An object of the present invention is to provide a sewing thread and a feather product using the sewing thread.
本発明者は上記の課題を達成するため鋭意検討した結果、鞘部および芯部がマルチフィラメントからなる芯鞘型複合糸で縫製糸を構成し、その際、鞘部がループを形成することにより、羽毛の吹き出し抑制（ダウンプルーフ性）に富み、かつ縫製後の縫目外観に優れた羽毛製品を得ることが可能な羽毛製品用縫製糸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 inventor constituted a sewing thread with a core-sheath type composite thread in which the sheath part and the core part are composed of multifilaments, and at that time, the sheath part formed a loop. By discovering that it is possible to obtain a feather product that is excellent in feather blowout suppression (down proofing) and that can provide a feather product with excellent stitch appearance after sewing. The present invention has been completed.

A feather product is obtained.
以下、本発明の実施の形態について詳細に説明する。
まず、本発明の羽毛製品用縫製糸は、芯鞘型複合糸であり、芯鞘型複合糸の鞘部および芯部がともにマルチフィラメント（長繊維）で構成される。芯鞘型複合糸の鞘部または芯部が紡績糸（スパン糸）の場合、表地を構成するマルチフィラメントとの統一感が乏しく縫製後の縫目外観が劣るため好ましくない。
ここで、鞘部を構成するマルチフィラメントおよび芯部を構成するマルチフィラメントが、ともに、ポリエステル成分を少なくとも１成分として含むポリエステル繊維からなることが、縫製糸の強度、耐候性、染色性などの点で好ましい。
Hereinafter, embodiments of the present invention will be described in detail.
First, the sewing thread for feather products of the present invention is a core-sheath type composite yarn, and both the sheath part and the core part of the core-sheath type composite thread are composed of multifilaments (long fibers). When the sheath part or the core part of the core-sheath composite yarn is a spun yarn (spun yarn), it is not preferable because the sense of unity with the multifilaments constituting the surface is poor and the stitch appearance after sewing is poor.
Here, the multifilament constituting the sheath part and the multifilament constituting the core part are both made of polyester fibers containing at least one polyester component, such as the strength, weather resistance, and dyeability of the sewing thread. Is preferable.
ポリエステル繊維を形成するポリエステルはジカルボン酸成分とジグリコール成分とから製造される。ジカルボン酸成分としては、主としてテレフタル酸が用いられることが好ましく、ジグリコール成分としては主としてエチレングリコール、トリメチレングリコール及びテトラメチレングリコールから選ばれた１種以上のアルキレングリコールを用いることが好ましい。また、ポリエステルには、前記ジカルボン酸成分及びグリコール成分の他に第３成分を含んでいてもよい。該第３成分としては、カチオン染料可染性アニオン成分、例えば、ナトリウムスルホイソフタル酸；テレフタル酸以外のジカルボン酸、例えばイソフタル酸、ナフタレンジカルボン酸、アジピン酸、セバシン酸；及びアルキレングリコール以外のグリコール化合物、例えばジエチレングリコール、ポリエチレングリコール、ビスフェノールＡ、ビスフェノールスルフォンの１種以上を用いることができる。かかるポリエステルとしては、ポリ乳酸などの生分解性を有するポリエステル、マテリアルリサイクルまたはケミカルリサイクルされたポリエステルであってもよい。また、特開２００４−２７００９７号公報や特開２００４−２１１２６８号公報に記載されているような、特定のリン化合物およびチタン化合物を含む触媒を用いて得られたポリエステルでもよい。さらには、ポリ乳酸やステレオコンプレックスポリ乳酸などの脂肪族ポリエステルであってもよい。該ポリエステルポリマー中には、本発明の目的を損なわない範囲内で必要に応じて、微細孔形成剤、カチオン染料可染剤、着色防止剤、熱安定剤、蛍光増白剤、艶消し剤、着色剤、吸湿剤、無機微粒子が１種または２種以上含まれていてもよい。 The polyester forming the polyester fiber is produced from a dicarboxylic acid component and a diglycol component. As the dicarboxylic acid component, terephthalic acid is preferably used mainly, and as the diglycol component, it is preferable to use one or more alkylene glycols selected from ethylene glycol, trimethylene glycol and tetramethylene glycol. Further, the polyester may contain a third component in addition to the dicarboxylic acid component and the glycol component. Examples of the third component include cationic dye dyeable anion components such as sodium sulfoisophthalic acid; dicarboxylic acids other than terephthalic acid such as isophthalic acid, naphthalenedicarboxylic acid, adipic acid, sebacic acid; and glycol compounds other than alkylene glycol. For example, one or more of diethylene glycol, polyethylene glycol, bisphenol A, and bisphenol sulfone can be used. Such polyester may be biodegradable polyester such as polylactic acid, material recycled or chemically recycled polyester. Moreover, the polyester obtained using the catalyst containing the specific phosphorus compound and titanium compound which are described in Unexamined-Japanese-Patent No. 2004-270097 and 2004-21268 may be sufficient. Furthermore, aliphatic polyesters such as polylactic acid and stereocomplex polylactic acid may be used. In the polyester polymer, a fine pore forming agent, a cationic dye dyeing agent, an anti-coloring agent, a heat stabilizer, a fluorescent whitening agent, a matting agent, as necessary within the range not impairing the object of the present invention, One or two or more colorants, hygroscopic agents, and inorganic fine particles may be contained.
鞘部を構成するマルチフィラメントおよび芯部を構成するマルチフィラメントにおいて、ともに総繊度が７０〜２１０ｄｔｅｘの範囲内であることが取扱い性の点で好ましい。単繊維繊度としては０．００１〜５ｄｔｅｘ（より好ましくは１〜４ｄｔｅｘ）、フィラメント数として１０〜２００本であることが好ましい。 In the multifilament constituting the sheath part and the multifilament constituting the core part, the total fineness is preferably in the range of 70 to 210 dtex from the viewpoint of handleability. The single fiber fineness is preferably 0.001 to 5 dtex (more preferably 1 to 4 dtex), and the number of filaments is preferably 10 to 200.
本発明の羽毛製品用縫製糸において、鞘部がループを形成していることが肝要である。鞘部がループを形成していることにより、羽毛の吹き出し抑制（ダウンプルーフ性）効果が向上する。
ここで、鞘部を構成するマルチフィラメントの巾Ａと芯部を構成するマルチフィラメントの巾Ｂとの比（Ａ：Ｂ）が１．１：１〜３：１の範囲内であることが好ましい。マルチフィラメントの巾Ａが該比よりも大きい場合、縫製後の縫目外観が損なわれるおそれがある。逆に、マルチフィラメントの巾Ａが該比よりも小さい場合、羽毛の吹き出し抑制（ダウンプルーフ性）の効果が低下するおそれがある。なお、鞘部を構成するマルチフィラメントの巾Ａと芯部を構成するマルチフィラメントの巾Ｂは、図１に示すように、鞘部を構成するマルチフィラメントＡと芯部を構成するマルチフィラメントの巾Ｂともに、最も外側〜最も外側までの距離をはかるものとし、ｎ数３でその平均値を算出する。
In the sewing thread for feather products of the present invention, it is important that the sheath part forms a loop. Since the sheath part forms a loop, the feather blowing out suppression (down proofing) effect is improved.
Here, it is preferable that the ratio (A: B) of the width A of the multifilament constituting the sheath portion to the width B of the multifilament constituting the core portion is in the range of 1.1: 1 to 3: 1. . When the width A of the multifilament is larger than the ratio, the stitch appearance after sewing may be impaired. On the other hand, when the width A of the multifilament is smaller than the ratio, the effect of suppressing feather blowing (down proofing) may be reduced. The width A of the multifilament constituting the sheath and the width B of the multifilament constituting the core are, as shown in FIG. 1, the width of the multifilament A constituting the sheath and the multifilament constituting the core. Both B shall measure the distance from the outermost side to the outermost side, and the average value is calculated by n number 3.
