Description
本発明は、スポーツ用衣料、ふとん側地、または中袋用織物に用いる薄地織物に関する。更に詳しくは、軽量、薄地でありながら、引裂き強度に優れた薄地織物、およびそれを用いた、スポーツ用衣料、ふとん側地、または中袋用織物に関する。 The present invention relates to a thin fabric used for sports clothing, a futon side fabric, or a fabric for an inner bag. More specifically, the present invention relates to a thin woven fabric that is lightweight and thin but has excellent tear strength, and sports clothing, futon side fabric, or a sack woven fabric using the same.
従来から、スポーツ用衣料用織物は、動きやすさの観点から軽量、薄地でありながら引裂き強度に優れることが望まれてきた。また、ふとんカバーやふとん中袋などふとん側地用途には、睡眠時の負荷やふとんの上げ下ろしの負荷を低減するため、あるいは寝袋用途に用いる為に軽量、薄地であり、かつ、引裂き強度を保持することが望まれてきた。しかし、織物を構成する糸の繊度を小さくし、織物を軽量、薄地にした場合には、引裂き強度も低下し、実用に支障をきたすという問題点があった。特にスポーツ用衣料の中でもダウンジャケット用生地や羽毛ふとん側地、ふとん中袋の場合には軽量、薄地化に加えてダウンプルーフ性が要求されるが、ダウンプルーフ性を満足するためには織物を緻密な構造にする必要があり、織物が硬くなるという問題点もあった。
特許文献１には、繊度が２５ｄｔｅｘ以下で詰め綿の側地として用いられ、樹脂加工が施されていない織物が開示されているが、２５ｄｔｅｘ以下の糸を使用した織物では、樹脂加工がされていない場合は、特許文献１に記載のようにポリアミド繊維を用いて織物にした場合は、８Ｎ以上にすることが可能であるが、特許文献１に開示されていない、例えば、ポリエステル繊維を用いた場合には織物の引裂き強度を８Ｎ以上にすることは困難であるという問題があった。
Conventionally, it has been desired that sports apparel fabrics are excellent in tear strength while being lightweight and thin from the viewpoint of ease of movement. In addition, for futon side areas such as futon covers and futon inner bags, it is lightweight, thin, and has good tear strength to reduce the load during sleeping and raising / lowering futon, or for sleeping bag applications. It has been desired to do. However, when the fineness of the yarn constituting the woven fabric is reduced and the woven fabric is light and thin, the tearing strength is reduced, which impedes practical use. In particular, in the case of sports clothing, down jacket fabrics, feather futon side linings, and futon inner sacks require light weight and down proofing in addition to thinning. There is also a problem that the fabric needs to be dense and the fabric becomes hard.
Patent Document 1 discloses a woven fabric that has a fineness of 25 dtex or less and is used as a side fabric of stuffed cotton, and is not subjected to resin processing. However, a woven fabric using yarns of 25 dtex or less is resin-processed. In the case where there is not, when it is made into a woven fabric using polyamide fibers as described in Patent Document 1, it is possible to make it 8N or more, but not disclosed in Patent Document 1, for example, using polyester fibers In some cases, it is difficult to make the tear strength of the fabric 8 N or more.
本発明は、軽量、薄地でありながら、引裂き強度に優れたスポーツ用衣料、あるいはふとん側地または中袋用織物を提供するものであり、特に、ポリエステル系繊維において、細い糸を用いて織物を作成した場合に、引裂き強度が小さいという問題を解決しようとするものである。 The present invention provides a sports apparel that is lightweight and thin, yet has excellent tear strength, or a fabric for a futon side fabric or an inner bag. When created, it is intended to solve the problem of low tear strength.

In order to solve the above-mentioned problems, the present inventor has found that a thin, lightweight fabric has sufficient tear strength by resin processing with a silicon-based resin, and has completed the present invention.
That is, the present invention is as follows.
(1) A woven fabric composed of synthetic fiber multifilaments, wherein the synthetic fiber multifilament has a fineness of 15 to 40 dtex, a fabric weight of 15 to 60 g / m 2 , a tear strength of 8 to 20 N, and a silicon-based resin A thin fabric that has been subjected to resin processing.
(2) The thin fabric according to (1) above, wherein the air permeability of the fabric is 0.3 to 1.5 cc / cm 2 · sec.
(3) The thin fabric as described in (1) or (2) above, wherein the cover factor of the fabric is 1300 to 2000.
(4) The thin woven fabric according to any one of (1) to (3) above, wherein the silicon-based resin is an emulsion of a modified silicone resin and a surfactant.
(5) The thin woven fabric according to any one of (1) to (4), wherein an adhesion amount of the silicon-based resin is 0.1 to 10 wt% with respect to the woven fabric.
(6) The thin woven fabric according to any one of (1) to (5) above, wherein the synthetic fiber multifilament is a polyester fiber or a polyamide fiber.
(7) The thin woven fabric according to any one of (1) to (6) above, wherein the woven fabric has a ripstop taffeta structure.
(8) A thin woven fabric characterized by using the thin woven fabric according to any one of (1) to (7) above for sports clothing, a futon side fabric, and a sack fabric.
本発明の薄地織物は、軽量、薄地でありながら、引裂き強度に優れ、やわらかく、すべりがよく、通気度が小さくダウンプルーフ性にも優れる薄地の織物であり、スポーツ用衣料、ふとん側地、または中袋用織物に好適である。 The thin woven fabric of the present invention is a thin woven fabric that is lightweight and thin, excellent in tearing strength, soft, slippery, low in air permeability and excellent in down-proofing properties, sports clothing, futon side fabric, or Suitable for woven fabric for inner bags.
本発明の薄地織物は、合成繊維マルチフィラメントで構成される。合成繊維の素材は特に限定されず、ポリエステル系繊維が好ましく、例えば、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレートあるいはそれらの共重合体であるポリエステル系繊維が挙げられる。また、ナイロン６、６６、６１０、６１２或いはその共重合体またはブレンド物であるポリアミド系繊維、ポリエチレン、ポリプロピレン等のポリオレフィン繊維等も好適に用いられる。
本発明においては、特に４０ｄｔｅｘ以下の糸で織物にした場合に引裂き強度に劣るポリエステル系繊維、あるいは、２０ｄｔｅｘ以下のポリアミド系繊維等に特に有効である。
The thin fabric of the present invention is composed of synthetic fiber multifilaments. The material of the synthetic fiber is not particularly limited, and a polyester fiber is preferable, and examples thereof include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, or a polyester fiber that is a copolymer thereof. Also, polyamide fibers such as nylon 6, 66, 610, 612 or copolymers or blends thereof, polyolefin fibers such as polyethylene and polypropylene, and the like are preferably used.
In the present invention, it is particularly effective for polyester fibers that are inferior in tear strength when made into a woven fabric with yarns of 40 dtex or less, or polyamide fibers that are 20 dtex or less.
本発明で用いるマルチフィラメントの単糸断面の形状は、特に限定されないが、異型度が２〜７の異型断面糸が好ましく、特に好ましくは異型度３以上の異型断面糸である。その形状はＷ型、Ｖ型、Ｔ型、扁平八葉型、ドッグボーン型、団子型である異型糸やその中空糸が好ましい。ここでいう異型度は後述する単糸繊維の断面の長径（最も長い部分の径）／短径（長径と垂直方向の径）より算出したものである。
異型度が２〜７であると、断面の長手方向を基調として、規則性を持って、単糸同士が集積しやすく、特にＷ型断面、Ｖ型断面繊維においては、織物にした場合には、所謂レンガ積み構造に配置され、最蜜充填に似た構造を呈し、そのため、単糸糸と単糸との間隙が小さくなり、通気性を低減させることができる。また、扁平形状単糸を用いると，糸による曲げ応力の低減効果の為、風合いがやわらかい織物となる。
また、異型度が２〜７の繊維のうち、Ｗ断面、Ｖ断面、めがね型断面等、異型断面繊維が溝、すなわち単糸断面に凹部を有する形状の場合、織物としての吸汗速乾性にも優れるため、汗をかいてもさらっとした衣料用織物或いはふとん側地となり、特に好ましい。
The shape of the cross section of the single filament of the multifilament used in the present invention is not particularly limited, but a modified cross-section yarn having a modified degree of 2 to 7 is preferable, and a modified sectional thread having a modified degree of 3 or more is particularly preferable. The shape is preferably W-type, V-type, T-type, flat eight-leaf type, dogbone type, dumpling type, or a hollow yarn thereof. The atypical degree here is calculated from the major axis (diameter of the longest part) / minor axis (major axis and vertical axis diameter) of the cross section of the single yarn fiber described later.
When the degree of atypicality is 2 to 7, the yarns are easy to accumulate with regularity based on the longitudinal direction of the cross section, especially in the case of W-shaped cross section and V-shaped cross section fiber, It arrange | positions in what is called a brick pile structure, and exhibits the structure similar to the honey-filling, Therefore, the clearance gap between a single yarn yarn and a single yarn becomes small, and air permeability can be reduced. In addition, when a flat single yarn is used, the fabric has a soft texture because of the effect of reducing the bending stress caused by the yarn.
In addition, among fibers having an atypical degree of 2 to 7, if the atypical cross-section fiber has a groove, that is, a shape having a recess in the single yarn cross-section, such as a W cross section, a V cross section, or a spectacle cross section, it can also absorb sweat quickly Since it is excellent, it becomes a garment fabric or a futon side fabric even if sweated, and is particularly preferable.
本発明の合成繊維マルチフィラメントの繊度は１５〜４０ｄｔｅｘ、好ましくは１５〜３０ｄｔｅｘである。４０ｄｔｅｘを超えると糸が太く、織物にした場合に厚く、硬くなり本発明の目的を達することができない。１５ｄｔｅｘより小さい場合には本発明の樹脂加工を施してもポリエステル系繊維を用いた場合には引裂き強度を８Ｎ以上にすることは困難である。また、本発明の織物の目付けは１５〜６０ｇ／ｍ2 であり、より好ましくは１５〜４０ｇ／ｍ2 である。織物をスポーツ衣料やふとん側地、特に羽毛ふとんの側地として使用した際に軽量感を感じる為には目付がこの範囲にある必要がある。１５ｇ／ｍ2 未満の場合には本発明の樹脂加工を施しても現状の繊維を用いた場合には引裂き強度を８Ｎ以上にすることは困難である。この目付を具現するために先述のマルチフィラメントの繊度は１５〜４０ｄｔｅｘ以下とする必要がある。ただし、織物の軽量薄地感と引裂き強度とを両立させるために５〜２０％程度の混率で４０〜６０ｄｔｅｘの糸を用いることは非常に好ましい。
マルチフィラメントの単糸繊度は特に限定されないが、通気性を低減し、やわらかい風合いにするために、単糸繊度は小さいほうが望ましく、０．５〜１．５ｄｔｅｘが特に好ましい。
The fineness of the synthetic fiber multifilament of the present invention is 15 to 40 dtex, preferably 15 to 30 dtex. If it exceeds 40 dtex, the yarn becomes thick, thick when it is made into a woven fabric, and becomes too hard to achieve the object of the present invention. If it is less than 15 dtex, it is difficult to make the tear strength 8 N or more when polyester fibers are used even if the resin processing of the present invention is applied. Moreover, the fabric weight of the textile fabric of this invention is 15-60 g / m < 2 >, More preferably, it is 15-40 g / m < 2 >. The fabric weight must be within this range in order to feel a light weight when the fabric is used as sports clothing or a futon side, especially as a side of a feather futon. If it is less than 15 g / m 2, it is difficult to increase the tear strength to 8 N or more when the present fiber is used even if the resin processing of the present invention is applied. In order to realize this basis weight, the fineness of the above-mentioned multifilament needs to be 15 to 40 dtex or less. However, it is very preferable to use a yarn of 40 to 60 dtex at a mixing ratio of about 5 to 20% in order to achieve both the lightweight thin ground feeling of the fabric and the tear strength.
The single yarn fineness of the multifilament is not particularly limited, but in order to reduce air permeability and make it soft, it is desirable that the single yarn fineness is small, and 0.5 to 1.5 dtex is particularly preferable.
本発明の特徴は、目付けが１５〜６０ｇ／ｍ2 と軽量薄地でありながら、引裂き強度が８〜２０Ｎであることにある。織物がスポーツ衣料やふとん側地等の実用に耐えるために引裂き強度は８〜２０Ｎ程度必要であり、８Ｎ未満では使用中に破れるおそれがある。また、２０Ｎを超えることは本発明の細い糸を用いた薄地織物では困難であり、実用上も必要ない。
軽量薄地でありながら引裂き強度を８〜２０Ｎにするためには、本発明の薄地織物はシリコン系樹脂による樹脂加工が施されていることを特徴としている。シリコン系樹脂の樹脂加工を薄地織物に加工することにより織物の引裂き強度が格段に向上することを見出し、本発明を完成した。シリコン系樹脂の樹脂加工剤はシリコンを含む樹脂であれば特に限定されないが、特に耐久性と加工性の観点から変性シリコン樹脂と界面活性剤とのエマルジョンが望ましい。変性シリコンの具体例としては、日華化学（株）製のニッカシリコンＤＭ−１００Ｅ、京浜化学（株）製のシリコランＥＣ、パラジンＭＢ、明成化学（株）製のハイソフターＫＲ−５０、クラリアントジャパンのＳｏｌｕｓｏｆｔ ＷＡなどが挙げられるがそれらに限定されるものではない。界面活性剤はシリコン樹脂のイオン性を考慮して適宜選定すればよい。
The feature of the present invention resides in that the tear strength is 8 to 20 N while the basis weight is 15 to 60 g / m 2 and it is light and thin. The tear strength is required to be about 8 to 20 N so that the woven fabric can withstand practical use such as sports clothing and futon side fabrics, and if it is less than 8 N, it may be broken during use. Moreover, exceeding 20 N is difficult in the thin fabric using the thin thread of the present invention, and is not necessary for practical use.
In order to set the tear strength to 8 to 20 N while being light and thin, the thin fabric of the present invention is characterized by being subjected to resin processing with a silicon-based resin. The present inventors have found that the tear strength of the woven fabric can be remarkably improved by processing the resin processing of the silicon-based resin into a thin woven fabric, thereby completing the present invention. The resin processing agent for silicon resin is not particularly limited as long as it is a resin containing silicon, but an emulsion of a modified silicone resin and a surfactant is particularly desirable from the viewpoint of durability and processability. Specific examples of modified silicon include Nikka Silicon Co., Ltd., DM-100E, Keihin Chemical Co., Ltd. Silicolan EC, Paladin MB, Meisei Chemical Co., Ltd. High Softer KR-50, Clariant Japan Examples thereof include, but are not limited to, Solosoft WA. The surfactant may be appropriately selected in consideration of the ionicity of the silicon resin.
シリコン系樹脂を薄地織物に樹脂加工することにより引裂き強度が向上する理由としては、シリコン系樹脂の樹脂加工により糸のすべり性が向上することに起因している。一般に、織物の引裂きは、引裂かれる点に応力が集中すると比較的小さい応力で引き裂かれてしまうが、シリコン系の樹脂加工により糸が滑ることにより引裂かれる点における応力が分散され、結果として、引裂き強度を高めることができ、従来、細い糸では引裂き強度が上がらなかったポリエステル系繊維を用いた織物においても引裂き強度を８Ｎ以上とすることが可能になる。
シリコン系樹脂の付与量は、生地に対し、０．１〜１０ｗｔ％が好ましい。特に０．５〜３ｗｔ％が目よれ等の欠点が起こり難く好ましい。付着量がこの範囲であると、樹脂なしに比較して、引裂き強度が１０〜５０％増加する。
The reason why the tear strength is improved by processing the silicon-based resin into a thin woven fabric is that the sliding property of the yarn is improved by the resin processing of the silicon-based resin. In general, tearing of a fabric is torn with a relatively small stress when the stress is concentrated at the point of tearing, but the stress at the point of tearing due to sliding of the yarn by silicon-based resin processing is dispersed, resulting in tearing. The strength can be increased, and the tear strength can be increased to 8 N or more even in a woven fabric using polyester fiber, which conventionally has not been improved with a thin thread.
The amount of silicon-based resin applied is preferably 0.1 to 10 wt% with respect to the fabric. In particular, 0.5 to 3 wt% is preferable because defects such as blurring hardly occur. When the adhesion amount is within this range, the tear strength increases by 10 to 50% as compared to the case without resin.
樹脂加工の方法は特に限定されないが、染色後にＤＩＰ−ＮＩＰ法で加工する方法、吸尽法で加工する方法、コーティング剤中に混ぜて加工するなどの方法が好適に用いられる。乾燥温度も通常の織物の仕上げ温度で特に問題はない。
シリコン系樹脂の樹脂加工を施すことで、引裂き強度向上効果に加えて、風合いをなめらか且つやわらかくする効果も同時に達成できる。この効果によりスポーツ衣料やふとん側地として用いた場合にがさがさ感がなく、肌触りが良好となる。
本発明の織物において、ダウンジャケットや羽毛ふとんの側地に用いる場合、ダウンプルーフ性を満足させる為、通気度が０．３〜１．５ｃｃ／ｃｍ2 ・ｓｅｃであることが好ましい。軽量でかつ通気度を０．３〜１．５ｃｃ／ｃｍ2 ・ｓｅｃにするには、細い糸で緻密にする必要があるが、この場合に引裂き強度を高め、風合いをやわらかくする観点から上述のシリコン系樹脂の樹脂加工が非常に好ましい。また、上述のように構成する合成繊維マルチフィラメントの異型度を２〜７にし、レンガ積み構造にすることは通気度の低減に有効である。さらに必要に応じて熱カレンダー加工を施すことが可能である。カレンダーによる目潰し効果も通気度低減に有効であり、ポリエステルを使用した織物の場合、１６０℃〜１８０℃でカレンダー加工することが通気度低減の上で好ましい。
The method of resin processing is not particularly limited, but a method of processing by DIP-NIP method after dyeing, a method of processing by exhaust method, and a method of mixing and processing in a coating agent are preferably used. There is no particular problem with the drying temperature, which is the normal finishing temperature of fabrics.
By performing the resin processing of the silicon-based resin, in addition to the effect of improving the tear strength, the effect of making the texture smooth and soft can be achieved at the same time. Due to this effect, when used as sports clothing or a futon side, there is no feeling of roughness and the touch is good.
In the woven fabric of the present invention, when used for the side of a down jacket or a down futon, the air permeability is preferably 0.3 to 1.5 cc / cm 2 · sec in order to satisfy the down-proof property. In order to reduce the air permeability to 0.3 to 1.5 cc / cm 2 · sec, it is necessary to make it fine with a thin thread. In this case, from the viewpoint of increasing the tear strength and softening the texture, Resin processing of silicon resin is very preferable. Moreover, it is effective for reduction of air permeability to make the atypical degree of the synthetic fiber multifilament constituted as described above 2 to 7 and to make a brick structure. Furthermore, it is possible to perform a heat calendar process as needed. The crushing effect by the calendar is also effective for reducing the air permeability, and in the case of a woven fabric using polyester, calendering at 160 ° C. to 180 ° C. is preferable for reducing the air permeability.
本発明の織物のカバーファクターは、１３００〜２０００であることが好ましく、より好ましくは１５００〜１８００である。カバーファクターをこの範囲に設定することで通気性の低減効果に優れた織物とすることができる。ここでいうカバーファクターは、経緯それぞれ繊度（ｄｔｅｘ）の平方根に密度（本／インチ）を掛け合わせ、経と緯の和で求めることができる。
本発明の織物の織り組織は特に限定されず、平織りの他、綾組織、朱子組織等任意の組織を用いることができ、これらの組織では、シリコン系樹脂での樹脂加工による引裂き強力の向上効果は、１０〜２０％である。
The cover factor of the fabric of the present invention is preferably 1300 to 2000, more preferably 1500 to 1800. By setting the cover factor within this range, a woven fabric excellent in the effect of reducing air permeability can be obtained. The cover factor here can be obtained by multiplying the square root of the fineness (dtex) by the density (lines / inch) and adding the warp and the latitude.
The woven structure of the woven fabric of the present invention is not particularly limited, and other than plain weave, any structure such as a twill structure, satin structure, etc. can be used. In these structures, the effect of improving the tear strength by resin processing with a silicon-based resin Is 10 to 20%.
また、織物生地としての、引裂き強力を上げるためリップストップタフタなどが特に好適に用いられる。特に、リップストップタフタの場合は、織組織の特異性とシリコン系樹脂の作用が、互いに相乗効果を発揮し、樹脂なしの生地に対し、３０〜５０％もの大幅な引裂強度の向上がみられる。リップストップタフタ組織の場合には、経糸又は横糸に、糸が２〜３本、多重で配列されているため、シリコン樹脂での滑り効果が顕著に生じやすくなるため、この様な優れた効果を生じたものと思われる。
また使用する織機も特に制限は無く、ウォータージェットルーム織機やエアージェットルーム織機、レピア織機を使用することができる。製織後の織物は常法に従って精錬、リラックス、プレセット、染色し、必要に応じて撥水処理やコーティング加工、カレンダー加工等の後加工を付与することができる。
こうして得られた織物は、従来のスポーツ用衣料あるいはふとん側地用織物よりも軽量でかつ引裂き強度が大きく、風合いもなめらかでやわらかいという特徴が有する。さらに通気性を小さくすることが可能であり、ダウンプルーフ性を併せ持つことができる。
Further, a ripstop taffeta or the like is particularly preferably used for increasing the tearing strength as a woven fabric. In particular, in the case of the ripstop taffeta, the peculiarity of the woven structure and the action of the silicon-based resin exert a synergistic effect with each other, and a significant improvement in tearing strength of 30 to 50% is seen with respect to the fabric without the resin. . In the case of the ripstop taffeta structure, two or three yarns are arranged in multiples on the warp or weft, so that the sliding effect of the silicone resin is likely to occur significantly. It seems to have occurred.
Also, the loom used is not particularly limited, and a water jet loom, an air jet loom, or a rapier loom can be used. The woven fabric after weaving can be refined, relaxed, preset, dyed according to a conventional method, and can be subjected to post-processing such as water repellent treatment, coating processing, calendar processing, etc., if necessary.
The fabric thus obtained has the characteristics that it is lighter, has higher tear strength, and has a smoother and softer texture than conventional sports clothing or futon side fabrics. Further, the air permeability can be reduced, and it is possible to have a down-proof property.

The texture of the fabric was good, and when this fabric was used for a down jacket, it was light and thin, and the strength was sufficient.
［実施例２］
織り組織を格子間隔が経緯それぞれ３ｍｍのリップストップタフタとした他は、実施例１と同様の方法で製織し、樹脂加工を行った。
得られた織物の特性は表１に示す通り、織物の繊度は、経糸２５ｄｔｅｘ，横糸２５ｄｔｅｘであり、厚みは０．０４ｍｍ、目付けは、３９ｇ／ｍ2 であり、引裂き強度は、タテが１０．２Ｎ、ヨコが１０．５Ｎであり、シリコン系樹脂なしの比較例２に対して、タテが４５％、ヨコが３５％と大幅な引裂強度の向上が見られた。

大幅な引裂強度の向上は、リップストップタフタ組織の場合には、経糸又は横糸に、糸が２〜３本、多重で配列されているため、シリコン樹脂での滑り効果が顕著に生じやすくなるため、この様な優れた効果を生じたものと思われる。
[Example 2]
Weaving was performed in the same manner as in Example 1 except that the woven structure was a ripstop taffeta with a lattice interval of 3 mm each, and resin processing was performed.
As shown in Table 1, the properties of the obtained woven fabric are as follows: the fineness of the woven fabric is warp 25 dtex and weft 25 dtex, the thickness is 0.04 mm, the basis weight is 39 g / m 2 , and the tear strength is 10. 2N and width were 10.5N.

The texture of the fabric was good, and when the woven fabric was used for the down jacket, it was light and thin, and the strength was sufficient.
In the case of a ripstop taffeta structure, a significant improvement in tear strength is due to the fact that two or three yarns are arranged in multiples on the warp or weft, so that the sliding effect of silicon resin is likely to occur significantly. It seems that such an excellent effect was produced.
