なお、上記工程１と工程２を合わせて、紡糸延伸工程というものとする。また、上記工程１、工程２、及び工程５を合わせて、一連の紡糸延伸巻取工程というものとする。
Note that the above steps 1 and 2 are combined to form a spinning and drawing step. Further, the above steps 1, 2, and 5 are combined to form a series of spinning, drawing, and winding steps.
上記延伸工程では、例えば加熱した引取ローラー（以下、第１ローラーともいう。）と、加熱した延伸ローラー（以下、第２ローラーともいう。）からなる２つのローラーを用いて、両ローラーの周速差によって延伸する方法を採用することができる。
In the stretching step, for example, two rollers including a heated take-up roller (hereinafter, also referred to as a first roller) and a heated stretching roller (hereinafter, also referred to as a second roller) are used, and the peripheral speeds of both rollers are used. A method of stretching by the difference can be adopted.
紡糸延伸工程における延伸前の糸に対する合成繊維用処理剤の付着量は、０．２質量％未満であることが好ましく、０．１質量％以下であることがより好ましく、０質量％であることがさらに好ましい。すなわち、延伸前の糸には、第１実施形態の処理剤も含めて、合成繊維用処理剤が付着していないことが好ましい。
The amount of the synthetic fiber treatment agent attached to the yarn before drawing in the spinning and drawing step is preferably less than 0.2% by mass, more preferably 0.1% by mass or less, and 0% by mass. Is more preferable. That is, it is preferable that the synthetic fiber treatment agent, including the treatment agent of the first embodiment, is not attached to the yarn before drawing.
延伸工程を経た延伸糸の糸速度は、特に限定されないが、糸速度３５００ｍ／分以上であることが好ましい。すなわち、巻取工程における延伸糸の巻取速度が、３５００ｍ／分以上であることが好ましい。かかる高速で走行する糸条に対しても付着性を低下させることがないため、効率的に希釈液を付与することができ、効率的に糸条の生産を行うことができる。
The yarn speed of the drawn yarn that has undergone the drawing step is not particularly limited, but is preferably a yarn speed of 3500 m / min or more. That is, it is preferable that the winding speed of the drawn yarn in the winding step is 3500 m / min or more. Since the adhesiveness is not lowered even for the yarn traveling at such a high speed, the diluted solution can be efficiently applied, and the yarn can be efficiently produced.
上記付与工程では、交絡延伸糸用処理剤の希釈液を、延伸糸に対し、交絡延伸糸用処理剤として０．１～３．０質量％の割合で付与することが好ましい。
In the above-mentioned applying step, it is preferable to apply the diluted solution of the confounding drawn yarn treatment agent to the drawn yarn at a ratio of 0.1 to 3.0% by mass as the confounding drawn yarn treatment agent.
上記交絡工程では、工程３を経た延伸糸をワインダーに巻き取る前に、繊維の進行方向に対して垂直方向からエアを吹き付けて、フィラメント同士を交絡させるインターレース加工（以下、Ｉ／Ｌ工程ともいう。）に延伸糸を供することが好ましい。
In the entanglement step, before winding the drawn yarn that has undergone step 3 on the winder, air is blown from a direction perpendicular to the traveling direction of the fibers to entangle the filaments with each other (hereinafter, also referred to as an I / L step). .) Is preferably provided with a drawn yarn.
本実施形態の希釈液、及び延伸糸によれば、以下のような効果を得ることができる。
According to the diluted solution and the drawn yarn of the present embodiment, the following effects can be obtained.
（１）本実施形態の希釈液は、界面活性剤を含む交絡延伸糸用処理剤、及び揮発性希釈剤を含有する。希釈液中における交絡延伸糸用処理剤及び揮発性希釈剤の含有割合の合計を１００質量％とすると、交絡延伸糸用処理剤を３０質量％以上且つ９４質量％未満、及び揮発性希釈剤を６質量％を超え且つ７０質量％以下の割合で含有している。また、希釈液は、延伸糸が巻き取られる前の位置で希釈液を延伸糸に付与する紡糸装置に適用される。
(1) The diluent of the present embodiment contains a treatment agent for confounding drawn yarn containing a surfactant and a volatile diluent. Assuming that the total content of the entangled drawn yarn treatment agent and the volatile diluent in the diluent is 100% by mass, the entangled drawn yarn treatment agent is 30% by mass or more and less than 94% by mass, and the volatile diluent is used. It is contained in a proportion of more than 6% by mass and 70% by mass or less. Further, the diluted solution is applied to a spinning device that applies the diluted solution to the drawn yarn at a position before the drawn yarn is wound.
延伸糸に対して希釈液を付着させることにより、エネルギー効率の低下を抑制することができる。さらに、加熱斑を抑制することができるため、延伸糸の染色性を良好にすることができ、糸品質の向上を図ることができる。また、延伸糸が巻き取られる前の位置で希釈液を延伸糸に付与する紡糸装置に希釈液が適用されることにより、交絡延伸糸の生産性の向上に寄与することができる。
By adhering the diluted solution to the drawn yarn, it is possible to suppress the decrease in energy efficiency. Further, since the heating spots can be suppressed, the dyeability of the drawn yarn can be improved, and the yarn quality can be improved. Further, by applying the diluted solution to the spinning device that applies the diluted solution to the drawn yarn at the position before the drawn yarn is wound, it is possible to contribute to the improvement of the productivity of the entangled drawn yarn.
（２）希釈液中の処理剤の濃度が低いと、Ｉ／Ｌ工程のエアで希釈液が飛散しやすくなる。また、希釈液中の処理剤の濃度が高いと、希釈液の塗布装置から希釈液が繊維に塗布されることなく落下する、所謂、オイルドロップが発生しやすくなる。本実施形態の希釈液は、希釈液中の処理剤の濃度が好適であるため、Ｉ／Ｌ工程での希釈液の飛散、及び希釈液の塗布装置におけるオイルドロップを抑制することができる。したがって、処理剤を効率良く延伸糸に付着させることができる。
(2) If the concentration of the treatment agent in the diluent is low, the diluent tends to scatter due to the air in the I / L process. Further, when the concentration of the treatment agent in the diluted solution is high, so-called oil drop, in which the diluted solution drops from the diluted solution application device without being applied to the fibers, is likely to occur. Since the diluted solution of the present embodiment has a suitable concentration of the treatment agent in the diluted solution, it is possible to suppress the scattering of the diluted solution in the I / L step and the oil drop in the diluted solution application device. Therefore, the treatment agent can be efficiently adhered to the drawn yarn.

A confounding drawn yarn was produced using a diluted solution of the treatment agent for confounding drawn yarn prepared in Test Category 1.
試験区分１で調製した交絡延伸糸用処理剤の希釈液を用いて、交絡延伸糸を製造した。 Test Category 2 (Manufacturing of entangled drawn yarn)
A confounding drawn yarn was produced using a diluted solution of the treatment agent for confounding drawn yarn prepared in Test Category 1.
まず、工程１として、ポリエステル繊維を溶融紡糸した。具体的には、固有粘度０．６４、酸化チタン含有量０．２％のポリエチレンテレフタラートのチップを常法により乾燥した後、溶融押出し機（エクストルーダー）を用いて２９５℃で溶融紡糸した。溶融紡糸した繊維を空気中で冷却して固化した。
First, as step 1, polyester fiber was melt-spun. Specifically, a polyethylene terephthalate chip having an intrinsic viscosity of 0.64 and a titanium oxide content of 0.2% was dried by a conventional method, and then melt-spun at 295 ° C. using a melt extruder (extruder). The melt-spun fibers were cooled in air and solidified.
次に、工程２として、溶融紡糸した繊維をガイドで集束させて、８０℃に加熱した第１ローラーに巻き掛けて、１５００ｍ／分の糸速度で引き取った。次いで、１３０℃に加熱した第２ローラーに巻き掛けて、４５００ｍ／分の糸速度となるように回転させることによって、第１ローラーと第２ローラーとの間で３倍に延伸した。
Next, as step 2, the melt-spun fibers were focused by a guide, wound around a first roller heated to 80 ° C., and picked up at a yarn speed of 1500 m / min. Then, the yarn was wound around a second roller heated to 130 ° C. and rotated to a yarn speed of 4500 m / min, whereby the yarn was stretched three times between the first roller and the second roller.
次に、工程３として、試験区分１で作製した交絡延伸糸用処理剤の希釈液を、計量ポンプを用いたガイド給油法にて、延伸糸に付与した。具体的には、希釈液の塗布装置として給油ガイドを用いた。給油ガイドは、走行中の繊維が接触するガイド本体を有しており、ガイド本体には吐出孔（給油ノズル）が設けられている。この吐出孔から本実施形態の希釈液が吐出されて繊維に付着するように構成されている。付与工程では、交絡延伸糸用処理剤の付着量が表２の目標処理剤付着量（質量％）となるように付与した。なお、上記給油ガイドは、紡糸された糸が延伸された後で、且つ巻き取られる前の位置で希釈液を延伸糸に付与する紡糸装置と言い換えることができる。
Next, as step 3, a diluted solution of the treatment agent for confounding drawn yarn produced in Test Category 1 was applied to the drawn yarn by a guide lubrication method using a measuring pump. Specifically, a refueling guide was used as a diluent coating device. The refueling guide has a guide main body with which the traveling fibers come into contact, and the guide main body is provided with a discharge hole (refueling nozzle). The diluted solution of the present embodiment is discharged from this discharge hole and is configured to adhere to the fiber. In the imparting step, the adhering amount of the treatment agent for entangled drawn yarn was applied so as to be the target adhering amount (mass%) of the treatment agent in Table 2. The refueling guide can be rephrased as a spinning device that applies a diluted solution to the drawn yarn at a position after the spun yarn is drawn and before it is wound up.
なお、比較例３、４では、延伸工程の後に付与工程を行なうことに代えて、延伸工程の前に付与工程を行なった。また、実施例１０、１１では、延伸工程の前と後の両方において、付与工程を行なった。
In Comparative Examples 3 and 4, the applying step was performed before the stretching step instead of performing the applying step after the stretching step. Further, in Examples 10 and 11, the applying step was performed both before and after the stretching step.
次に、工程４として、交絡延伸糸用処理剤の希釈液が付着した延伸糸に対して、インターレースノズル（以下、Ｉ／Ｌノズルともいう。）からエアを吹き付けて、Ｉ／Ｌ工程を行った。工程５として、Ｉ／Ｌ工程を行った繊維をワインダーに巻き取った。得られた交絡延伸糸は、８３．３デシテックス（７５デニール）３６フィラメントのポリエステル繊維であった。
Next, as step 4, air is blown from an interlaced nozzle (hereinafter, also referred to as an I / L nozzle) to the drawn yarn to which the diluted solution of the confounding drawn yarn treatment agent is attached, and the I / L step is performed. rice field.
