When the number of turns (after boiling water treatment) is 120 or more, a swelling feeling is easily obtained by the untwisting untwisting torque of the composite yarn, and a woven or knitted fabric with stretchability is obtained. If the number of turns (after boiling water treatment) is 190 or less, the untwisting and untwisting torque of the composite yarn will not be too strong, and yarn jump-out in the dyeing process can be prevented.
ここで、旋回数（沸水処理前）とは糸の解撚トルクの強さを現す数値であり、ＪＩＳ−Ｌ１０９５スナール指数Ａ法に基づきポリエステルマルチフィラメント糸長５０ｃｍの試料の中央部に８．８２ｍＮ×繊度（ｄｔｅｘ）の荷重を掛け、糸両端を１ｃｍ／秒の速度で糸端間を１０ｃｍまで接近させる。通常法の場合、初めて旋回し始めた間隔を読み取るが、糸端の移動速度の差によりばらつきが生じやすい。この為糸端を１０ｃｍの間隔で固定し、糸の持つ解撚トルクによって糸が旋回し捩れたスナル状態部分の撚り数Ｔ（／１０ｃｍ）を検撚機で測定した。また、旋回数（ 沸水処理後）とは、旋回数（沸水処理前）の測定と同様にして糸端を１０ｃｍまで接近させ、糸が旋回し捩れたスナル状態部分をクリップで固定し、沸水中で１分間湿熱処理した後のスナル状態部分の撚り数Ｔ（／１０ｃｍ）を検撚機で測定した。 Here, the number of swirling (before boiling water treatment) is a numerical value representing the strength of the untwisting torque of the yarn, and 8.82 mN at the center of a sample of a polyester multifilament yarn length of 50 cm based on the JIS-L1095 Snarn index A method. X A load of fineness (dtex) is applied, and both ends of the yarn are brought closer to 10 cm at a speed of 1 cm / second. In the case of the normal method, the interval at which the first turning starts is read, but variations are likely to occur due to the difference in the movement speed of the yarn end. For this reason, the yarn ends were fixed at an interval of 10 cm, and the twist number T (/ 10 cm) of the snull state portion where the yarn was turned by the untwisting torque of the yarn and twisted was measured with a tester. Also, the number of turns (after boiling water treatment) is the same as the measurement of the number of turns (before boiling water treatment). The yarn end is brought close to 10 cm, and the snurled portion where the yarn turns and is twisted is fixed with a clip. The twist number T (/ 10 cm) of the snull state part after the wet heat treatment for 1 minute was measured with a tester.
また本発明では、撚糸工程の安定化の為、沸水処理前と沸水処理後の旋回数の差が５０以上であることが好ましい。沸水処理前後の旋回数差は、染色時に発現する潜在的に有する解撚トルクを示し、撚糸工程等準備工程でのビリつきが少なくなり、染色工程での湿熱下の処理でトルク発現が充分に発揮でき、十分なふくらみ感とストレッチ性が得られる。 In the present invention, in order to stabilize the twisting process, it is preferable that the difference in the number of turns before and after boiling water treatment is 50 or more. The difference in the number of swirling before and after boiling water treatment indicates the potential untwisting torque that appears at the time of dyeing, less wobble in the preparation process such as the twisting process, and sufficient torque expression by the treatment under wet heat in the dyeing process It can be demonstrated, and a sufficient swell and stretchability can be obtained.
次に、本発明の複合繊維布帛の製造法の一例を説明する。 Next, an example of the manufacturing method of the composite fiber fabric of this invention is demonstrated.
また本発明のセルロース系フィラメント糸は、その製法や種類を特に限定するものではないが、アセテート繊維がその低屈折率からくる鮮明性、発色性、高級感のある光沢、適度なヤング率、分散染料可染性（カチオン染料可染性を有する品種もある）等を有しており好ましく用いられる。ちなみにジアセテートの公定水分率は約６．５%、トリアセテートは約３．５%であり適度な吸湿性と速乾性を有し、沸水収縮率も約２〜３％と少ない。また風合いや光沢の高級感の点からトリアセテートの使用が更に好ましい。 The cellulose-based filament yarn of the present invention is not particularly limited in its production method and type, but the acetate fiber is vivid due to its low refractive index, color developability, high-quality gloss, appropriate Young's modulus, dispersion It is preferably used because it has dyeability (some varieties have cationic dyeability). By the way, the official moisture content of diacetate is about 6.5%, triacetate is about 3.5%, it has moderate hygroscopicity and quick drying, and the boiling water shrinkage is about 2-3%. Further, triacetate is more preferable from the viewpoint of texture and glossiness.
これらのポリエステルマルチフィラメント糸とセルロース系マルチフィラメント糸を、ポリエステルマルチフィラメント糸の有する旋回方向と逆方向で合撚し、撚糸セット温度８５℃度以下で処理した複合糸を織編し、染色することで、本発明の複合繊維布帛が得られる。 These polyester multifilament yarns and cellulosic multifilament yarns are twisted in the direction opposite to the swirling direction of the polyester multifilament yarns, and the composite yarn processed at a twisted yarn set temperature of 85 ° C or less is knitted and dyed. Thus, the composite fiber fabric of the present invention is obtained.
