This flame-retardant fabric mainly uses flame-retardant fibers such as meta-aramid fibers and para-aramid fibers, and it is generally considered difficult to impart elasticity.
一方、難燃性繊維を使った布帛に伸縮性を付与するため、弾性糸や複合繊維などの伸縮繊維を用いる方法などが提案されている（例えば、特許文献１〜４参照）。
しかしながら、難燃性繊維と伸縮繊維との糸足差の影響で表面品位不良やピリングなどの問題があった。
On the other hand, in order to impart elasticity to a fabric using flame-retardant fibers, a method of using elastic fibers such as elastic yarns and composite fibers has been proposed (see, for example, Patent Documents 1 to 4).
However, there have been problems such as poor surface quality and pilling due to the influence of the difference in yarn content between the flame-retardant fiber and the stretchable fiber.
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、難燃性と伸縮性だけでなく表面品位にも優れた布帛および繊維製品を提供することにある。 The present invention has been made in view of the above background, and an object of the present invention is to provide a fabric and a textile product having excellent surface quality as well as flame retardancy and elasticity.

本発明において、布帛には前記の紡績糸と前記の伸縮繊維が含まれる。その際、前記の紡績糸と前記の伸縮繊維とが、両者の複合糸として布帛に含まれることが好ましい。複合糸に含まれる複合繊維の重量比率としては、難燃性と伸縮性とを両立させる上で、複合繊維の重量比率は複合糸重量対比２〜４０重量％（より好ましくは４〜３０重量％、特に好ましくは４〜２０重量％）の範囲内であることが好ましい。 In the present invention, the fabric includes the spun yarn and the elastic fiber. At that time, it is preferable that the spun yarn and the elastic fiber are contained in the fabric as a composite yarn of both. As for the weight ratio of the composite fiber contained in the composite yarn, the weight ratio of the composite fiber is 2 to 40% by weight (more preferably 4 to 30% by weight) with respect to the weight of the composite yarn in order to achieve both flame retardancy and elasticity. , Particularly preferably in the range of 4 to 20% by weight).
前記複合糸において、複合方法は特に限定されないが、合撚糸条またはカバリング糸であることが好ましい。より具体的には、前記の紡績糸と複合繊維とを用いて、市販のアップツイスタ、カバリング機、イタリ式撚糸機、ダブルツイスタなどを使用して、合撚またはカバリングすることが好ましい。その際、撚り止めセットは要求される品質により実施しても良い。複合合撚糸の撚り止めセットは、通常の紡績糸のセットに用いられる真空スチームセットを用いる事ができる。複合合撚糸のセット時の温度は、５０〜９５℃（より好ましくは５０〜８５℃）の範囲が好ましい。複合合撚糸の撚り止めセット温度が高過ぎると、最終的に得られる布帛の伸縮性が損なわれるおそれがある。 In the composite yarn, the composite method is not particularly limited, but a twisted yarn or a covering yarn is preferable.

The temperature at the time of setting the composite plyed yarn is preferably in the range of 50 to 95 ° C. (more preferably 50 to 85 ° C.). If the anti-twist set temperature of the composite plyed yarn is too high, the elasticity of the finally obtained fabric may be impaired.

実施例１において、複合糸Ｂは使用せず、経糸および緯糸に難燃合撚糸Ａを１００％配して織り成したこと以外は、実施例１と同様にした。評価結果を表２に示す。
[Comparative Example 1]
In Example 1, the composite yarn B was not used, and the warp and weft were woven with 100% flame-retardant plyed yarn A in the same manner as in Example 1. The evaluation results are shown in Table 2.
［比較例２］
実施例１において、複合繊維として、固有粘度が互いに異なる２種類のポリトリメチレンテレフタレートを偏心芯鞘型に貼り合せた総繊度１６５ｄｔｅｘ／２４フィラメント、伸度４１％、沸水収縮率４２．０％のマルチフィラメント（長繊維）を用いること以外は実施例１と同様にした。評価結果を表２に示す。
[Comparative Example 2]
In Example 1, as a composite fiber, two types of polytrimethylene terephthalates having different intrinsic viscosities are bonded together in an eccentric core sheath type, and the total fineness is 165 dtex / 24 filament, the elongation is 41%, and the boiling water shrinkage rate is 42.0%. The procedure was the same as in Example 1 except that the multifilament (long fiber) was used. The evaluation results are shown in Table 2.
［比較例３］
比較例２で得られた複合糸を１００％用いて、２０ゲージの１口編機を用いて編成し、
実施例１と同様にした。評価結果を表２に示す。
[Comparative Example 3]
Using 100% of the composite yarn obtained in Comparative Example 2, knitting was performed using a 20-gauge single-mouth knitting machine.
The same as in Example 1. The evaluation results are shown in Table 2.
［実施例４］
実施例１において、複合繊維を市販のポリウレタン繊維に変更した以外は、実施例１と同様にした。評価結果を表２に示す。
[Example 4]
In Example 1, the same was applied to Example 1 except that the composite fiber was changed to a commercially available polyurethane fiber. The evaluation results are shown in Table 2.
［実施例５］
実施例１において、難燃レーヨン繊維を省き、紡績糸の重量割合（帝人コーネックス：テクノーラ）９５：５の割合で混紡した。これ以外は実施例１と同様にした。評価結果を表２に示す。
[Example 5]
In Example 1, the flame-retardant rayon fiber was omitted, and the spun yarn was blended at a weight ratio (Teijin Cornex: Technora) 95: 5. Other than this, it was the same as in Example 1. The evaluation results are shown in Table 2.
本発明によれば、難燃性と伸縮性だけでなく表面品位にも優れた布帛および繊維製品が提供され、その工業的価値は極めて大である。 According to the present invention, fabrics and textile products having excellent surface quality as well as flame retardancy and elasticity are provided, and their industrial value is extremely large.
Claims (11)
糸足差＝（（紡績糸長＜ｃｍ＞−１０＜ｃｍ＞）／１０＜ｃｍ＞）×１００
ただし、生地緯糸部１０ｃｍをカットし、初荷重を繊度＜ｄｔｅｘ＞／３６＜ｇｒ＞で紡績糸の長さの差を測定する。 The fabric according to any one of claims 1 to 7, wherein the yarn difference shown in the following formula is 3 to 20%.
Thread difference = ((spun yarn length <cm> -10 <cm>) / 10 <cm>) × 100
However, the fabric weft portion 10 cm is cut, and the difference in the lengths of the spun yarns is measured with the initial load of fineness <dtex> / 36 <gr>.
