＜綿紡績装置を用いた紡績糸の製造方法＞
綿紡績で使用される設備を用いる場合は前記高収縮アクリル繊維（ａ）を３８ｍｍに定長カットした原綿を用いることができる。紡績糸の原材料比率になるように、高収縮アクリル繊維（ａ）、低収縮アクリル繊維（ｂ−１）及び他の繊維（ｂ−２）の各繊維を計量したのち、高収縮アクリル繊維（ａ）のみを開綿機に投入する。開綿した原材料を打綿機に投入した後、ラップを形成する。次にラップをフラットカードに投入し、スライバーを作成する。また、ラップを形成することなく開綿工程から直接フラットカードに原料を投入してもよい。使用するフラットカードのトップ数は７０本以上、出来れば１００本以上ある機台が望ましく、品位向上の為には固定フラットを装備した機台が望ましい。スライバー作成後、練条工程を２回通したのち、粗紡工程を経て、粗糸（Ａ）を作成する。この場合の粗糸重量を０．２５〜０．４０ｇ／ｍに設定する。
<Method for producing spun yarn using a cotton spinning device>
In the case of using equipment used in cotton spinning, raw cotton obtained by cutting the high-shrinkage acrylic fiber (a) to a constant length of 38 mm can be used. After measuring each fiber of the high shrinkage acrylic fiber (a), the low shrinkage acrylic fiber (b-1) and the other fiber (b-2) so that the raw material ratio of the spun yarn is obtained, the high shrinkage acrylic fiber (a ) Only into the opening machine. A wrap is formed after the opened raw material is put into a cotton blower. Next, put the lap into the flat card and create a sliver. Moreover, you may throw a raw material into a flat card | curd directly from a cotton opening process, without forming a wrap. The number of flat cards used is preferably 70 or more, preferably 100 or more, and a machine equipped with a fixed flat is desirable for improving the quality. After creating the sliver, after passing through the drawing process twice, the roving process is performed to prepare the roving yarn (A). The roving weight in this case is set to 0.25 to 0.40 g / m.
次に低収縮アクリル繊維（ｂ−１）と、他の繊維（ｂ−２）として綿繊維、レーヨン繊維または羊毛を開綿機に投入し、打綿機に投入後、ラップを形成する。ラップを同様のフラットカードに投入にスライバー作成後、練条工程を2回通したのち、粗紡工程を経て粗糸（Ｂ）を作成する。この場合の粗糸重量を０．３５〜０．６０ｇ／ｍに設定する。 Next, low shrinkage acrylic fibers (b-1) and cotton fibers, rayon fibers or wool as other fibers (b-2) are put into a cotton opening machine, and then put into a cotton blower and a wrap is formed. A sliver is prepared by putting the wrap into the same flat card, and after passing through the drawing process twice, the roving process is followed to prepare the roving yarn (B). The roving weight in this case is set to 0.35 to 0.60 g / m.
次に粗糸（Ａ）と粗糸（Ｂ）をダブルロービング手法で精紡工程に投入する。この場合、合わせた粗糸重量が１．０ｇ／ｍを超えると目標とする番手に対するドラフト倍率が４０倍を超え品質的に、不安定な状態となるため、粗糸重量を１．０ｇ／ｍ以下にする。また、合わせた粗糸重量が０．６ｇ／ｍより少ないと粗糸（Ａ）、粗糸（Ｂ）の粗糸強力が不足し、粗糸切れが頻発する事で精紡工程の効率が著しく低下するため、粗糸重量を０．６ｇ／ｍ以上にする。作成する紡績糸は、例えば、メートル番手４０ＮＭで撚り数は５７０回で設定する。ワインダー工程において紡績糸中の欠点除去を行った後、コーンに巻き取る。その後、紡績糸を２本合わせて双糸としてもよい。この時、例えば、双糸の撚り数は２９０回に設定する。その後、２．３５ｍ枠周の綛機で綛とする。 Next, the roving yarn (A) and the roving yarn (B) are put into the spinning process by a double roving method. In this case, if the combined roving weight exceeds 1.0 g / m, the draft magnification with respect to the target count exceeds 40 times, and the quality becomes unstable. Therefore, the roving weight is 1.0 g / m. Below. In addition, if the combined roving weight is less than 0.6 g / m, the roving strength of roving yarn (A) and roving yarn (B) is insufficient, and the efficiency of the spinning process is remarkably caused by frequent cutting of roving yarn. In order to decrease, the roving weight is set to 0.6 g / m or more. The spun yarn to be created is set, for example, with a metric count of 40 NM and a twist count of 570 times. After removing the defects in the spun yarn in the winder process, the wound yarn is wound around a cone. Thereafter, two spun yarns may be combined into a double yarn. At this time, for example, the number of twists of the double yarn is set to 290 times. After that, it will be dredged with a 2.35m frame dredge.
（精紡工程の撚り数設定方法）
収縮糸の性能を引き出す為には、紡績糸の撚り数が多すぎると熱収縮性に弊害が出ることから、紡績糸撚り係数を８０〜９５の間で設定することが好ましい。紡績糸撚り数は下記式により決定される。
紡績糸撚り数（回／ｍ）＝紡績糸撚り係数（α） × √紡績糸番手（ＮＭ）
(Method of setting the number of twists in the spinning process)
In order to bring out the performance of the shrink yarn, it is preferable to set the spun yarn twist coefficient between 80 and 95, because if the number of twists of the spun yarn is too large, the heat shrinkability is adversely affected. The number of spun yarn twists is determined by the following formula.
Number of twists of spun yarn (times / m) = twisted factor of spun yarn (α) × √number of spun yarn (NM)
（双糸撚り数）
双糸撚り数は、紡績糸の持つ撚りトルクを抑え、染色後の収縮性を阻害しない程度に設定するとよい。撚り数は紡績糸撚り数の５割となるように設定するとする。
双糸撚り数（回／ｍ）＝紡績糸撚り数（回／ｍ） × ０．５
(Number of twin yarn twist)
The number of twists of the twin yarn is preferably set to a level that suppresses the twisting torque of the spun yarn and does not hinder the shrinkage after dyeing. The number of twists is set to be 50% of the number of twisted spun yarns.
Number of twists of twin yarn (times / m) = Number of twists of spun yarn (times / m) × 0.5
（綛工程）
例えば、熱水収縮後の綛枠周が１．４ｍ〜１．６ｍの場合、綛工程は綛枠周が２．３０ｍ〜２．４０ｍである綛機を用いるとよい。
(Coffee process)
For example, when the periphery of the frame after hot water shrinkage is 1.4 m to 1.6 m, the dredging process may use a dredge with a frame frame periphery of 2.30 m to 2.40 m.
＜染色方法＞
綛染色には、綛染色機を用いる。収縮発現の為、綛染色機に綛をセットした後、染色前に９０度以上の熱水で２０分間染色機台内部を満たすか、熱水の代わりに蒸気を１０分間吹き込むことで糸の収縮を発現させる。以後の工程は通常のアクリル混紡品の染色工程と同様に行う。例えば、カチオン染料を用いて４５℃の染色液を１℃／２分の温度上昇条件で液温を１００℃とした後、その状態を２０分間保持し、仕上げ処理・糸洗浄をおこなった後、つづいて反応染料を用いた同様の工程を繰り返す。
その後、糸乾燥工程を経た後、綛からコーン形状に糸を巻き取る。この時、巻き取り
張力が高いと、糸の膨らみが減少するので注意する。
<Dyeing method>
Amber dyeing machine is used for the amber dyeing. For shrinkage, after setting the cocoon in the cocoon dyeing machine, fill the inside of the dyeing machine table with hot water of 90 degrees or more for 20 minutes before dyeing, or blow the steam for 10 minutes instead of hot water to shrink the yarn. To express. Subsequent processes are performed in the same manner as the dyeing process for ordinary acrylic blends. For example, after using a cationic dye to make a dye solution at 45 ° C. under a temperature increase condition of 1 ° C./2 minutes and keeping the temperature at 100 ° C., the state is maintained for 20 minutes, and after finishing and washing the yarn, Subsequently, the same process using the reactive dye is repeated.
Then, after passing through a yarn drying step, the yarn is wound into a cone shape from the ridge. At this time, it should be noted that if the winding tension is high, the swelling of the yarn decreases.
＜編地作成方法＞
編み立て工程では、例えば、１２ゲージ２４口の編機を用いて、編み立てを実施していくが、糸の走行テンションが１０〜２５ｇの範囲を超えると、染色で発現した糸の膨らみが無くなるので注意する。
<Knitting method>
In the knitting process, for example, knitting is performed using a knitting machine having 12 gauges and 24 ports. However, when the running tension of the yarn exceeds the range of 10 to 25 g, the swelling of the yarn expressed by dyeing disappears. So be careful.

Example 1
After obtaining a copolymer consisting of 91% by mass of acrylonitrile units and 9% by mass of vinyl acetate units by an aqueous suspension polymerization method, the copolymer is then dissolved in dimethylacetamide, and spinning with a copolymer concentration of 20% by mass is performed. A stock solution was obtained. The spinning dope was wet-spun in a coagulation bath using a nozzle having a round shaped discharge hole, 60% by mass of a dimethylacetamide component, 40% by mass of water, and a temperature of 40 ° C. As the nozzle, a nozzle having a discharge hole of 0.008 mm and a hole number of 15000 was used. Subsequently, the solvent was washed in boiling water and then stretched 5 times.

As the nozzle, a nozzle having a discharge hole of 0.008 mm and a hole number of 20000 was used. Subsequently, the solvent was washed in boiling water and then stretched 5 times. Subsequently, after attaching an oil agent, drying with a heat roller at 150 ° C., passing through a heat relaxation process, passing through a steam stretching process of 1.05 times, cut to a fiber length of 38 mm, and a low-shrinkage acrylic fiber having a hollow bean cross section ( b) (Single fiber fineness 1.0 dtex, fiber length 38 mm, boiling water shrinkage 1 to 3%, manufactured by Mitsubishi Rayon Co., Ltd., product name: Bonnell H616) was obtained.
紡績糸での原綿比率に基づいて、前記の高収縮性アクリル繊維（ａ）（ボンネルＶ８５）４０質量％と低収縮性アクリル繊維（ｂ−１）（ボンネルＨ６１６）３０質量％と綿繊維（品名 米綿サンホーキン）３０質量％とを計量した。計量した高収縮性アクリル繊維（ボンネルＶ８５）のみを、綿紡績工程に投入し開綿工程を経たのちフラットカードを用いてスライバーを作成した。作成したスライバーを練条工程に３回通過させた後、粗紡工程において０．３５ｇ／ｍの粗糸（Ａ）を作成した。 Based on the raw cotton ratio in the spun yarn, the high-shrinkage acrylic fiber (a) (Bonnel V85) 40% by mass, the low-shrinkage acrylic fiber (b-1) (Bonnel H616) 30% by mass and the cotton fiber (product name) (US cotton San Hawkin) 30% by mass was weighed. Only the weighed high-shrinkage acrylic fiber (Bonnell V85) was put into the cotton spinning process, and after the cotton-opening process, a sliver was created using a flat card. The prepared sliver was passed through the drawing process three times, and then a roving (A) of 0.35 g / m was prepared in the roving process.
次に、コーマ通しを行った綿繊維と前記ボンネルＨ６１６とを、粗糸（Ａ）と同様に綿紡績工程に投入し、開綿工程を経たのちフラットカードを用いてスライバーを作成した。作成したスライバーを練条工程に３回通過させた後、粗紡工程において０．５３ｇ／ｍの粗糸（Ｂ）を作成した。作成した粗糸（Ａ）と粗糸（Ｂ）とを、粗糸供給口がセパレートタイプに変更しているリング精紡機に準備したのち、ダブルロービング手法によって紡績糸を作成した。紡績機フロントトップローラーには、コレクターをセットしておいた。紡績糸はメートル番手で４０番、撚り数は５７０回／ｍとなるように設定した。 Next, the combed cotton fiber and the Bonnell H616 were put into the cotton spinning process in the same manner as the roving yarn (A), and after passing through the cotton opening process, a sliver was created using a flat card. The prepared sliver was passed through the drawing process three times, and then a roving yarn (B) of 0.53 g / m was prepared in the roving process. The prepared roving (A) and roving (B) were prepared in a ring spinning machine whose roving supply port was changed to a separate type, and then spun yarn was prepared by a double roving method. A collector was set on the front top roller of the spinning machine. The spun yarn was set to a meter count of 40 and the number of twists was 570 times / m.
作成した紡績糸をワインダー工程にて糸欠点を除去してコーン形状に巻き取った後、合糸工程、撚糸工程を経て、双糸を作成した。作成した双糸を、綛枠周が２．３５ｍである綛機を用いて、綛状態とした。この時の、１綛当りの重量は２５０ｇとした。作成した綛を綛染色機にセットした後、染料投入前に加熱用の蒸気を１０分間吹き込んだ後、充分に糸収縮が発現した事を確認したのち、通常のアクリル混紡糸の染色と同様の工程で染色・乾燥を行った。乾燥後の糸を、綛からコーン状態に巻き取った。この時、糸の巻き取り張力を１０〜３０ｇにするように注意した。糸張力が高すぎると、染色工程で得る事のできた糸の膨らみが消失してしまうためである。染色糸の巻き取り終了後に、１２ゲージ２４口のニット機を使用して、編地作成を行った。この工程でも同様に、発現している糸収縮を減少させないように１０〜２０ｇの張力管理を行った。作成した編地を用いて、外観、風合い評価及び保温性能評価を実施し、表１にまとめた。 The produced spun yarn was wound into a corn shape by removing the yarn defects in a winder process, and then a twin yarn was produced through a combination yarn process and a twisting process. The created twin yarn was put into a cocoon state using a cocoon machine having a cocoon frame circumference of 2.35 m. At this time, the weight per liter was 250 g. After the prepared cocoon is set in the cocoon dyeing machine, the steam for heating is blown for 10 minutes before adding the dye, and after confirming that the yarn shrinkage is sufficiently developed, it is the same as the dyeing of ordinary acrylic blended yarn. Dyeing and drying were performed in the process. The dried yarn was wound from a cocoon into a corn state. At this time, attention was paid so that the winding tension of the yarn was 10 to 30 g. This is because if the yarn tension is too high, the swelling of the yarn that can be obtained in the dyeing process will disappear. After finishing the winding of the dyed yarn, a knitted fabric was prepared using a 12 gauge 24 port knit machine. Similarly, in this step, 10 to 20 g of tension was controlled so as not to reduce the yarn shrinkage that was developed. Using the prepared knitted fabric, appearance, texture evaluation and heat insulation performance evaluation were carried out and summarized in Table 1.
