　本発明は、薄地軽量織物に関する。より詳しくは、本発明は、軽量・薄地でありながら、バイアス変形時にも低通気性が維持されるスポーツ衣料等用の薄地軽量織物に関する。 The present invention relates to a thin lightweight fabric. More specifically, the present invention relates to a thin lightweight fabric for sports clothing or the like that is light and thin and maintains low air permeability even when bias is deformed.
　以下の特許文献１には、翼用クロスとして、撥水加工、カレンダー加工を行い、低目付で、バイアス方向に変形しにくく、通気度が殆どないリップストップ織物が開示されている。しかしながら、ポリウレタン系及びアクリル酸エステル系等の合成樹脂で被膜することで、バイアス方向への変形が小さくなっているために、織物が厚く、重くなり、更に風合いが劣り衣料用織物への適用は困難である。 The following Patent Document 1 discloses a ripstop woven fabric that is water-repellent and calendered as a wing cloth, is low in weight, hardly deforms in the bias direction, and has almost no air permeability. However, since the deformation in the bias direction is reduced by coating with a synthetic resin such as polyurethane and acrylic ester, the fabric becomes thicker and heavier, and the texture is inferior. Have difficulty.
　また、以下の特許文献２には、２８ｄｔｅｘ以下の合成繊維で構成され、モノフィラメント同士が２層に配列されているマルチフィラメントを存在させることで、織物の通気度を低減させ、洗濯等による通気度の悪化を抑制することが開示されている。しかしながら、通気度を低減させるには単糸数、単糸繊度が限定されるという問題があった。 Patent Document 2 below includes a multifilament made of synthetic fibers of 28 dtex or less and in which monofilaments are arranged in two layers, thereby reducing the air permeability of the fabric and the air permeability due to washing or the like. It is disclosed to suppress the deterioration of. However, in order to reduce the air permeability, there is a problem that the number of single yarns and the single yarn fineness are limited.
　さらに、以下の特許文献３には、経糸の総繊度が３０デシテックス以下で、耐水圧が８００ｍｍＨ２０以上、洗濯後の耐水保持率が５０％以上となる防水性ポリエステル織物が開示されている。しかしながら、通気度の規定はなく、特にバイアス変形時の通気性を満足できなかった。 Further, Patent Document 3 below, the total fineness of the warp 30 dtex or less, water pressure resistance 800mmH 2 0 or more, waterproof polyester fabric is disclosed water retention after washing becomes 50% or more. However, there was no regulation of the air permeability, and the air permeability especially at the time of bias deformation could not be satisfied.

　かかる従来技術の問題に鑑み、本発明が解決しようとする課題は、ダウンウェア、ダウンジャケット、布団、寝袋等の側地に好適に用いることができ、かつ、バイアス変形時にも、低通気性を維持できる薄地軽量織物を提供することである。 In view of the problems of the prior art, the problem to be solved by the present invention can be suitably used for side areas such as downwear, down jackets, futons, sleeping bags, etc., and has low air permeability even during bias deformation.

　本発明に係る薄地軽量織物は、目付が１５～５０ｇ／ｍ２と薄地軽量でありながら、該織物を構成する経糸と緯糸の断面における隣り合うモノフィラメントの重なり度を経緯のいずれかで０．６以上とする、すなわち、隣り合う単糸（フィラメント）の重なり合う程度を所定範囲とすることにより、バイアス変形時の通気度が小さく、ダウンプルーフ性にも優れる織物であるため、スポーツ衣料、ふとん側地、中袋用織物等に好適に利用可能である。 The thin lightweight fabric according to the present invention is thin and lightweight with a basis weight of 15 to 50 g / m 2 , but the overlapping degree of adjacent monofilaments in the cross section of the warp and the weft constituting the fabric is 0.6 for any of the backgrounds. In other words, because the degree of overlap between adjacent single yarns (filaments) is within a predetermined range, the air permeability during bias deformation is small and the fabric is excellent in down-proofing.

バイアス変形後通気度測定法を説明する概略図である。It is the schematic explaining the air permeability measurement method after a bias deformation | transformation. 断面における隣り合うモノフィラメントの重なり状態を示す織物断面写真例とその判定基準の解説である。It is the example of the textile cross-section photograph which shows the overlapping state of the adjacent monofilament in a cross section, and the description of the criterion.
　以下、本発明の実施形態を詳細に説明する。
　本実施形態の薄地軽量織物は、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、ポリエチレンアフタレート、又はそれらの共重合体であるポリエステル系繊維、あるいはナイロン６、６６、６１０、６１２又はその共重合体若しく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が好適に用いられる。 Hereinafter, embodiments of the present invention will be described in detail.
The thin lightweight fabric of this embodiment is composed of synthetic fiber multifilaments. The material of the synthetic fiber is not particularly limited, and polyester fiber such as polyethylene terephthalate, polytrimethylene terephthalate, polyethylene aphthalate, or a copolymer thereof, nylon 6, 66, 610, 612 or a copolymer thereof or Polyamide fibers such as polyamide fibers, polyethylene, and polypropylene, which are blends, are preferably used.
　合成繊維マルチフィラメントの単糸断面の形状は、特に限定されず、丸断面以外にも異形断面でも構わない。異形断面の形状は三角、Ｙ字型、十字型、Ｗ型、Ｖ型等が挙げられるが、強度の面から丸断面が好適に用いられる。 The shape of the single yarn cross section of the synthetic fiber multifilament is not particularly limited, and may be an irregular cross section other than the round cross section. Examples of the shape of the irregular cross section include a triangle, a Y shape, a cross shape, a W shape, and a V shape. A round cross section is preferably used in terms of strength.
　合成繊維マルチフィラメントの繊度は、好ましくは５～４０ｄｔｅｘ、より好ましくは１０～３３ｄｔｅｘ、さらに好ましくは１０～２５ｄｔｅｘである。４０ｄｔｅｘを超えると糸が太く、織物にした場合に厚く、硬くなり薄地軽量織物とならない。また、５ｄｔｅｘより小さくした場合には、製織性が困難となり、カバーファクターを上げても隣り合う単糸（フィラメント）が重ならず、バイアス変形での通気度が高くなる。 The fineness of the synthetic fiber multifilament is preferably 5 to 40 dtex, more preferably 10 to 33 dtex, and still more preferably 10 to 25 dtex. If it exceeds 40 dtex, the yarn is thick, and when it is made into a woven fabric, it becomes thick and hard and does not become a thin lightweight fabric. In addition, when it is smaller than 5 dtex, weaving becomes difficult, and even if the cover factor is increased, adjacent single yarns (filaments) do not overlap, and the air permeability in bias deformation increases.
　単糸フィラメント繊度は、好ましくは０．８～２．０ｄｔｅｘ、より好ましくは０．８～１．５ｄｔｅｘである。単糸フィラメント繊度が０．８ｄｔｅｘより小さい場合には、マルチフィラメントになるため、経糸及び緯糸の断面における隣り合うモノフィラメントの重なり度（係数）は大きくなるが、引裂き強度低下の懸念がある。単糸フィラメント繊度が２．０ｄｔｅｘより大きい場合には、単糸フィラメントが少なくなるため、経糸及び／又は緯糸の断面における隣り合うモノフィラメントの重なり度が小さくなることや、風合いが堅くなる懸念がある。 The single yarn filament fineness is preferably 0.8 to 2.0 dtex, more preferably 0.8 to 1.5 dtex. When the single yarn filament fineness is smaller than 0.8 dtex, it becomes a multifilament, so that the overlapping degree (coefficient) of adjacent monofilaments in the warp and weft cross sections is increased, but there is a concern that the tear strength may be reduced. When the single yarn filament fineness is larger than 2.0 dtex, the number of single yarn filaments decreases, so that there is a concern that the overlapping degree of adjacent monofilaments in the cross section of the warp and / or weft will be small and the texture will be stiff.
　本実施形態の薄地軽量織物の織組織は特に限定されないが、タフタ、リップストップタフタ、綾組織、朱子組織等任意の組織を用いることができる。このうち特にタフタ、リップストップタフタは、縦糸と緯糸との交点を多く持ち、バイアス変形後の経糸及び緯糸の隣り合う糸の重なりが減少し難いため、通気度変化が少なく、好適に用いられる。 The woven structure of the thin lightweight fabric of this embodiment is not particularly limited, but any structure such as taffeta, ripstop taffeta, twill structure, satin structure, etc. can be used. Of these, the taffeta and the ripstop taffeta are particularly preferred because they have many intersections between the warp and the weft and the overlap between the warp and the weft adjacent to each other after the bias deformation is difficult to reduce.
　本実施形態の薄地軽量織物の目付けは１５～５０ｇ／ｍ２であり、好ましくは２０～４０ｇ／ｍ２である。織物をスポーツ衣料やふとん側地、特にダウンジャケットや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５０ｇ／ｍ２以下であればよい。１５ｇ／ｍ２以上であれば、織物組織を調整して樹脂加工を施すことにより引き裂き強度を８Ｎ以上にすることができる。 The basis weight of the thin lightweight fabric of this embodiment is 15 to 50 g / m 2 , preferably 20 to 40 g / m 2 . In order to feel a light feeling when the woven fabric is used as a side of sports clothing or a futon side, especially a down jacket or a down futon, the basis weight may be 50 g / m 2 or less. If it is 15 g / m 2 or more, the tear strength can be increased to 8 N or more by adjusting the fabric structure and applying resin processing.
　本実施形態の薄地軽量織物は、薄地・軽量でありながら、引き裂き強度が大きいことが好ましい。引き裂き強度は、ＪＩＳ－Ｌ－１０９６：８．１５．５ Ｄ法（ベンジュラム法）で測定されるもので、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、引き裂き強度が７Ｎ～２０Ｎ程度であることが好ましい。７Ｎ以上であれば使用中に破れるおそれはなく、また、２０Ｎ以下であれば前記細い糸を用いた薄地織物の実用を可能とする。 It is preferable that the thin lightweight fabric of this embodiment has a high tear strength while being thin and lightweight. The tear strength is measured by the JIS-L-1096: 8.15.5 D method (Benjuram method), and the tear strength is 7N to 20N in order to withstand the practical use of sports clothing and futon side fabrics. It is preferable that it is a grade. If it is 7N or more, there is no risk of tearing during use, and if it is 20N or less, a thin woven fabric using the thin thread can be put into practical use.
　本実施形態の薄地軽量織物は、経糸のカバーファクターカバーと緯糸のカバーファクターの和（以下の式で表されるカバーファクター）が１３００～２２００であることが好ましく、１５００～２０００であることが好ましい。
　　　カバーファクター＝経糸密度（本／２．５４ｃｍ）×√経糸繊度（ｄｔｅｘ）＋緯糸密度（本／２．５４ｃｍ）×√（緯糸繊度）
　ここで、経糸密度と緯糸密度の単位は（本／２．５４ｃｍ）である。
　カバーファクターが１３００未満であると軽量ではあるが、縦糸及び／又は緯糸の重なりが小さいため、バイアス変形後の通気度が大きくなり好ましくなく、また、２２００を超えると高密度化しバイアス変形後の通気度変化は小さいものの、目付が大きくなりやすいため好ましくない。 In the thin lightweight fabric of this embodiment, the sum of the cover factor of the warp and the cover factor of the weft (the cover factor represented by the following formula) is preferably 1300 to 2200, and preferably 1500 to 2000. .
Cover factor = warp density (main / 2.54 cm) × √warp fineness (dtex) + weft density (main / 2.54 cm) × √ (weft fineness)
Here, the unit of the warp density and the weft density is (line / 2.54 cm).
If the cover factor is less than 1300, the weight is light, but the overlap of warp and / or weft is small, which increases the air permeability after bias deformation, which is not preferred. Although the degree of change is small, it is not preferable because the basis weight tends to increase.
　薄地軽量織物を構成する経糸及び緯糸の断面における隣り合うモノフィラメントの重なり度（係数）は、後述する断面写真から算出したときに経緯のいずれかで０．６～１であることが必要であり、好ましくは０．８～１である。経緯いずれかについて重なり度が本範囲であればよく、経糸の重なりが本範囲であればより好ましく、経緯両方向とも重なり度が本範囲であることが特に好ましい。ここで、本発明における重なり度とは、隣り合う経糸または緯糸同士の重なり有無を計５０箇所について観察した時に、隣り合う糸が重なっている箇所の比率である。経緯の重なり度がいずれも０．６未満であると縦糸及び／又は緯糸間に空隙ができやすく、初期通気度やバイアス変形後の通気度が高くなる傾向にある。 The degree of overlap (coefficient) of adjacent monofilaments in the cross section of the warp and weft constituting the thin lightweight fabric needs to be 0.6 to 1 in either of the warp when calculated from the cross-sectional photograph described below, Preferably it is 0.8-1. The degree of overlap may be in this range for any of the backgrounds, more preferably the overlap of warps is in this range, and it is particularly preferable that the degree of overlap is in this range in both directions of the background. Here, the degree of overlap in the present invention is the ratio of the places where adjacent yarns overlap when the presence or absence of overlap between adjacent warps or wefts is observed for a total of 50 locations. If the degree of overlap of the wefts is less than 0.6, voids are likely to be formed between the warp and / or the wefts, and the initial air permeability and the air permeability after bias deformation tend to increase.
　特に、薄地軽量織物を、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ため、通気度が０．３～１．５ｃｃ／ｃｍ２・ｓｅｃであることが好ましく、より好ましくは０．３～１．０ｃｃ／ｃｍ２・ｓｅｃである。
　また、バイアス変形後においても、通気度が０．３～１．５ｃｃ／ｃｍ２・ｓｅｃであることが好ましく、より好ましくは０．３～１．０ｃｃ／ｃｍ２・ｓｅｃである。織物の通気度が前記範囲内にあれば、織物から中綿等が抜けにくいため好ましい。 In particular, when a thin lightweight fabric is 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, more preferably, in order to satisfy the down-proof property. Is 0.3 to 1.0 cc / cm 2 · sec.
Moreover, even after the bias deformation, it is preferable that the air permeability is 0.3 ~ 1.5cc / cm 2 · sec , more preferably 0.3 ~ 1.0cc / cm 2 · sec . If the air permeability of the woven fabric is within the above range, it is preferable because the batting and the like are not easily removed from the woven fabric.
　滑り効果を発揮させるためにシリコーン樹脂加工する場合、その付着量は、生地に対し０．１～１０．０ｗｔ％であることが好ましい。特に、シリコーン樹脂の付着量は、生地に対し０．５～３．０ｗｔ％であることが、目よれなど他の欠点が起こりにくくなる点でより好ましい。付着量がこの範囲であると、シリコーン樹脂のない場合に比較して、引き裂き強度が１０～５０％増加する。シリコーン樹脂の付着量が１０％以上の場合、引裂きは向上するものの、バイアス変形が大きくなるため、バイアス変形後の通気度が大きくなり、ダウン性能を出すことができなくなる。 When the silicone resin is processed in order to exert a sliding effect, the adhesion amount is preferably 0.1 to 10.0 wt% with respect to the fabric. In particular, the adhesion amount of the silicone resin is more preferably 0.5 to 3.0 wt% with respect to the dough, from the viewpoint that other defects such as blurring hardly occur. When the adhesion amount is within this range, the tear strength is increased by 10 to 50% as compared to the case without the silicone resin. When the adhesion amount of the silicone resin is 10% or more, the tearing is improved, but the bias deformation becomes large. Therefore, the air permeability after the bias deformation becomes large, and the down performance cannot be obtained.
　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。加工工程の最終段階で生地表面にしっかり加工剤を付着させるという点でＤＩＰ－ＮＩＰ法で加工する方法が特に好適に用いられる。乾燥温度も通常の織物の仕上げ温度で特に問題はない。シリコーン系の樹脂加工を施すことで、引き裂き強度向上効果に加えて、風合いをなめらかか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。 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. A method of processing by the DIP-NIP method is particularly preferably used in that the processing agent is firmly attached to the surface of the fabric at the final stage of the processing process. There is no particular problem with the drying temperature, which is the normal finishing temperature of fabrics. By applying the silicone resin processing, 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.
　織物を構成する経糸と緯糸の断面における隣り合うモノフィラメントの重なり度が経緯のいずれかで０．６以上にするためには、加工工程でのカレンダー条件が非常に重要である。薄地織物の場合、特に、ダウン等の詰め綿を使用する用途では、ダウンの抜けを抑えるためにカレンダー加工が使用されることが多く、カレンダーで表面の繊維を熱で圧することにより、通気性を抑え、ダウン抜けを抑えている。しかし、過度にカレンダー加工を行うと、マルチフィラメントにおけるモノフィラメントは過度に圧縮され、また経糸及び／又は緯糸の重なり度は大きくなるものの、織物引裂き強力が著しく低下するおそれがある。カレンダー加工を特殊な条件で行い、表面の状態をコントロールすることで、バイアス変形時にも低通気性が維持される。 In order for the degree of overlap of adjacent monofilaments in the cross section of the warp and weft constituting the woven fabric to be 0.6 or more in any one of the wefts, the calendar condition in the processing step is very important. In the case of thin fabrics, especially in applications that use padded cotton such as down, calendering is often used to suppress the loss of down, and by pressing the fibers on the surface with heat with a calender, breathability can be increased. Suppresses and keeps down. However, if the calendering is performed excessively, the monofilament in the multifilament is excessively compressed and the overlapping degree of the warp and / or weft is increased, but the fabric tearing strength may be significantly reduced. By performing calendering under special conditions and controlling the surface condition, low air permeability is maintained even during bias deformation.
　織物を構成する経糸と緯糸の断面における隣り合うモノフィラメントの重なり度が経緯のいずれかで０．６以上にするためには、具体的にはカレンダーロールの種類、圧力、温度、スピードをコントロールする。適正なカレンダー温度は、織物を構成する素材によって異なり、素材のガラス転移点をＴＧ（℃）、融点をＴＭ（℃）とするとき、（ＴＧ＋ＴＭ）／２－３０℃～（ＴＧ＋ＴＭ）／２＋３０℃にするのが好ましく、より好ましくは（ＴＧ＋ＴＭ）／２－２０℃～（ＴＧ＋ＴＭ）／２＋２０℃であり、さらに好ましくは（ＴＧ＋ＴＭ）／２－１５℃～（ＴＧ＋ＴＭ）／２＋１５℃である。織物が複数素材の混用品である場合には、カレンダーの金属面が当たる側の繊維素材のうち、最も低いガラス転移点、融点を採用する。カレンダー温度が高すぎると織物表面は硬くなり、また、バイアス変形時の通気性が維持されず、好ましくない。カレンダー温度が低すぎると通気が大きく、該織物を構成する経糸と緯糸の断面における隣り合うモノフィラメントの重なり度が小さくなり、好ましくない。 In order for the degree of overlap of adjacent monofilaments in the cross section of the warp and weft constituting the woven fabric to be 0.6 or more in any of the warps, specifically, the type, pressure, temperature, and speed of the calendar roll are controlled. The appropriate calendar temperature varies depending on the material composing the fabric. When the glass transition point of the material is TG (° C.) and the melting point is TM (° C.), (TG + TM) / 2-30 ° C. to (TG + TM) / 2 + 30 ° C. It is preferably (TG + TM) / 2-20 ° C. to (TG + TM) / 2 + 20 ° C., more preferably (TG + TM) / 2-15 ° C. to (TG + TM) / 2 + 15 ° C. When the woven fabric is a mixed product of a plurality of materials, the lowest glass transition point and melting point are adopted among the fiber materials on the side where the metal surface of the calendar hits. If the calendar temperature is too high, the surface of the fabric becomes hard, and air permeability during bias deformation is not maintained, which is not preferable. If the calendar temperature is too low, the ventilation is large, and the degree of overlap between adjacent monofilaments in the cross section of the warp and weft constituting the woven fabric becomes small, which is not preferable.
　カレンダー圧力は、１００～８００ｋｇｆ／ｃｍ（ロール幅１６０ｃｍあたりの値。このときの生地幅が１５０ｃｍであれば１６～１２８ｔ（トン）／１５０ｃｍ幅）であることが好ましく、２００～６００ｋｇｆ／ｃｍ（３２～９６ｔ）がより好ましい。圧力をかけすぎると、生地が硬くなり、また、織物を構成する経糸と緯糸の断面における隣り合うモノフィラメントの重なり度は大きくなるが、バイアス変形時の通気度が大きくなるため、好ましくない。また、圧力が低すぎると生地の初期通気度が大きくなり、また、織物を構成する経糸と緯糸の断面における隣り合うモノフィラメントの重なり度が小さくなるため、好ましくない。カレンダースピードも重要であり、５～３０ｍ／ｍｉｎでカレンダー加工するのが好ましく、１０～２０ｍ／ｍｉｎが特に好ましい。 The calendar pressure is preferably 100 to 800 kgf / cm (value per roll width of 160 cm. If the fabric width at this time is 150 cm, it is preferably 16 to 128 t (tons) / 150 cm width), and 200 to 600 kgf / cm (32 ~ 96t) is more preferred. If too much pressure is applied, the fabric becomes hard and the degree of overlap between adjacent monofilaments in the cross section of the warp and weft constituting the fabric increases, but the air permeability during bias deformation increases, which is not preferable. On the other hand, if the pressure is too low, the initial air permeability of the fabric increases, and the degree of overlap between adjacent monofilaments in the cross section of the warp and weft constituting the fabric decreases, which is not preferable. The calendar speed is also important, and calendar processing is preferable at 5 to 30 m / min, and 10 to 20 m / min is particularly preferable.
　カレンダーロール温度をＴ（℃）、圧力をＰ（ｔ／生地幅１５０ｃｍ）、スピードをＳ（ｍ／ｍｉｎ）とするとき、｛Ｔ－（ＴＧ＋ＴＭ）／２｝／２＋（Ｐ－２５）＋（１０－Ｓ）で計算されるカレンダー指数は、１０～５０であることが好ましく、より好ましくは１５～４０である。このカレンダー指数１５～４０の条件で２～３回加工することがさらに好ましい。このような条件を用いることで、バイアス変形時にも低通気度を維持することができる。 When the calendar roll temperature is T (° C.), the pressure is P (t / bread width 150 cm), and the speed is S (m / min), {T− (TG + TM) / 2} / 2 + (P−25) + ( The calendar index calculated by 10-S) is preferably 10 to 50, more preferably 15 to 40. It is more preferable to perform the processing 2 to 3 times under the condition of the calendar index 15 to 40. By using such conditions, a low air permeability can be maintained even during bias deformation.
　また、カレンダーの材質は特に限定されないが、片方のロールは金属製であることが好ましい。金属ロールはそれ自身の温度を調節することができ、かつ生地表面を均一に圧縮することができる。もう一方のロールは特に限定されないが、金属ロール以外にもペーパーロール、コットンロール、樹脂ロール等の弾性ロールを用いてもよい。樹脂ロールを用いる場合は表面材質としてナイロン製が好ましく用いられる。
　ナイロン原糸は水分の影響を受けることで、膨潤し通気度の影響を受けやすいが、早期に冷却をし、生地温度を５０℃以下にすることで、原糸の固定化、ひいては糸－糸間の積層が強固になりバイアス変形における、積層のズレ、即ち通気度増加を抑制することができる。 The material of the calendar is not particularly limited, but one of the rolls is preferably made of metal. The metal roll can adjust its own temperature and can uniformly compress the dough surface. The other roll is not particularly limited, but an elastic roll such as a paper roll, a cotton roll, and a resin roll may be used in addition to the metal roll. When a resin roll is used, nylon is preferably used as the surface material.
Nylon yarn is swollen and susceptible to air permeability due to the influence of moisture, but it is cooled early and the fabric temperature is set to 50 ° C or below, so that the yarn can be fixed and eventually yarn-thread. The lamination between the layers becomes strong, and deviation of the lamination, that is, increase in air permeability in bias deformation can be suppressed.
　織物の製織に使用する織機は、特に制限はなく、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、レピア織機を用いることができる。製織後の織物は常法に従って精練、リラックス、プレセット、染色し必要に応じて撥水処理、吸水加工、抗菌、消臭などの機能付与加工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。 The loom used for weaving the fabric is not particularly limited, and a water jet loom loom, an air jet loom loom, or a rapier loom can be used. The woven fabric after weaving is scoured, relaxed, preset, dyed according to conventional methods, and given post-processing such as water-repellent treatment, water absorption processing, antibacterial treatment, deodorization, etc. be able to.
　こうして得た織物は、従来のスポーツ用衣料やふとん側地用織物よりも軽量であり、かつ、引き裂き強度や摩耗強度が大きく、風合いもなめらかで柔らかく、さらに低通気度であるため、ダウンプルーフ性を併せ持つものとなる。 The fabric obtained in this way is lighter than conventional sports clothing and fabric for futon, has a high tear strength and wear strength, is soft and soft, and has low air permeability, so it is down proof. It will have both.
