【発明の詳細な説明】 本発明は、湿式紡糸に於ける流浴紡糸方法に関する。更
に詳しくは内面が平滑な流管を用いた高速流浴紡糸方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flow bath spinning method in wet spinning. More specifically, it relates to a high-speed flow bath spinning method using a flow tube having a smooth inner surface.
湿式紡糸に於て、生産性を向上する為に高速度紡糸を行
うに際しては、形成された糸条が、凝固浴中を走行する
間に、浴抵抗をできるだけ減少しておく事が好ましい。
この為、形成された糸条を流動する凝固浴中に導びき走
行せしめる流浴紡糸方法が用いられる。When performing high-speed spinning for improving productivity in wet spinning, it is preferable to reduce the bath resistance of the formed yarn as much as possible while running in the coagulation bath.
Therefore, a flow bath spinning method is used in which the formed yarn is guided and run in a flowing coagulation bath.
流浴紡糸方法では、凝固浴中を走行する糸条速度と凝固
浴流速との差、即ち糸と凝固浴の相対速度が小さけれ
ば、小さい程好ましい。In the flow bath spinning method, the smaller the difference between the yarn speed running in the coagulation bath and the coagulation bath flow velocity, that is, the smaller the relative speed between the yarn and the coagulation bath, the better.
従って、生産性向上の要請に応え、紡糸速度を高めるに
は、流浴紡糸では凝固浴の流速を高めてゆく方法があっ
た。Therefore, in order to increase the spinning speed in response to the demand for improved productivity, there has been a method of increasing the flow velocity of the coagulation bath in the flow bath spinning.
ところが、この様な方法では、糸条と凝固浴が流管を出
た後、糸条を捲取等の後工程に走行せしめる為に、糸条
と凝固浴を分離する際に問題が発生する。However, in such a method, after the yarn and the coagulating bath leave the flow tube, the yarn is allowed to run to a subsequent process such as winding, so that there is a problem in separating the yarn and the coagulating bath. .
即ち、流管を出た後に糸条を凝固浴より分離しようとし
ても、速い凝固浴流の為に、糸条が取られ切糸が発生し
たり、糸条の単糸が取られ毛羽を発生したり、糸条の単
糸が取られ切断までには至らぬが部分的に伸長された単
糸たるみが生じる欠点があった。That is, even if an attempt is made to separate the yarn from the coagulation bath after leaving the flow tube, due to the fast coagulation bath flow, the yarn is taken off and the cutting yarn is generated, or the single yarn of the yarn is taken out and fluff is generated. However, there is a drawback that a single yarn of a yarn is taken and a slack of a partially extended single yarn is generated before cutting.
この様な欠点は、単糸の自己接着性を有するキュプラア
ンモニウムセルロース原液を除き、多くの湿式紡糸方法
に出現し、且つより生産性を向上する目的で高速度運転
を目指すと障害になるものであった。Such a defect appears in many wet spinning methods except for cupraammonium cellulose stock solution having a self-adhesive property of single yarn, and becomes an obstacle when aiming at high speed operation for the purpose of improving productivity. there were.
本発明者等は、高速度で流浴紡糸を行っても、流管出口
での糸条と凝固浴流の分離が容易で、凝固浴流に糸条又
は単糸が取られない流浴紡糸方法を検討してきた結果、
本発明に到達した。The present inventors have found that even if spinning bath spinning is performed at a high speed, it is easy to separate the filament and the coagulating bath stream at the outlet of the flow tube, and the filament or single yarn is not taken in the coagulating bath stream. As a result of examining the method,
The present invention has been reached.
すなわち、本発明は、流管を用いる流浴紡糸方法におい
て、上記流管の内面がガラス製のように平滑であって、
上記流管出口の糸条が進行する側の管内面又は管外面の
少なくとも一つの面に欠損部を設けた流管を用いる事を
特徴とする高速流浴紡糸方法である。That is, the present invention, in a flow bath spinning method using a flow tube, the inner surface of the flow tube is smooth like glass,
A high-speed flow-bath spinning method, characterized in that a flow tube provided with a defect in at least one of the inner surface or the outer surface of the tube on the side where the yarn advances at the outlet of the tube is used.
本発明でいう流管出口の糸条が進行する側の管内面又は
管外面の少なくとも一つの面に設けた欠損部とは、流管
の出口面であって、出口面と管の内面又は外面とをつな
ぐものであればよく、その大きさは極めて微少のもので
充分であるが、好ましくは長さ(周方向)が0.5〜
1.0mm、巾(半径方向)が0.5〜1.0mm、深
さ(軸方向)が0.05〜0.2mmのものである。In the present invention, the defect portion provided on at least one surface of the pipe inner surface or the pipe outer surface of the flow tube outlet on the side where the yarn advances is the outlet surface of the flow tube, and the outlet surface and the inner surface or the outer surface of the pipe. It suffices as long as it can connect to and the size thereof is extremely small, but the length (circumferential direction) is preferably 0.5 to
The thickness is 1.0 mm, the width (radial direction) is 0.5 to 1.0 mm, and the depth (axial direction) is 0.05 to 0.2 mm.
流管出口の糸条が進行する側に欠損部を設けた流管を用
いて流浴紡糸を行うと、流管出口の糸条が進行する側に
おいて、流出する凝固浴内に向けて大量の大気を気泡状
で吸入する事が判った。When flow bath spinning is carried out using a flow tube having a defect on the side where the yarn at the outlet of the flow tube advances, a large amount of water is discharged toward the inside of the coagulating bath at the side where the yarn at the outlet of the flow tube advances. It was found to inhale the air in the form of bubbles.
凝固浴内に吸入された大気は、気泡状でよく分散し、光
を当てて凝固浴流を観際すると、その部分の光沢が変わ
るので判るし、又流れる凝固浴を受けて目視でもその気
泡状態は良く観察出来る。The air inhaled in the coagulation bath is well dispersed in the form of bubbles, and when observing the coagulation bath flow by shining light, it can be seen that the gloss of that part changes, and also when the coagulation bath that flows is visually inspected The condition can be observed well.
この出口面の糸条が進行する側に欠損部を設けた流管を
用いて、流浴紡糸を実施してみると、従来法に比べ、流
管を出た後に糸条と凝固浴の分離が極めてスムースに実
施出来、糸条または単糸が凝固浴に取られ難い事が判っ
た。When the flow tube spinning was carried out using a flow tube with a defect on the yarn advancing side of the exit surface, when compared with the conventional method, the separation of the thread from the coagulation bath after the flow tube was separated. However, it was found that the yarn or the single yarn was difficult to be taken in the coagulation bath.
恐らく、凝固浴中に分散した気泡が、凝固浴へ糸条、又
は単糸が取られる事を妨げている事と思われる。Possibly, the air bubbles dispersed in the coagulation bath prevent the yarn or single yarn from being taken into the coagulation bath.
本発明方法の効果は、極めて簡単な方法で凝固浴と糸条
の分離を容易にするのみならず、糸条が凝固終了した位
置、すなわち、流管の出口で凝固浴流系に外乱を与える
だけなので、糸条形成に何等悪い影響を及ぼさない点に
ある。The effect of the method of the present invention is not only to facilitate the separation of the coagulation bath and the yarn in a very simple manner, but also to give a disturbance to the coagulation bath flow system at the position where the yarn has finished coagulation, that is, at the outlet of the flow tube. Since it is only, there is no adverse effect on the yarn formation.
更に、本発明方法を図面を用いて説明する。Further, the method of the present invention will be described with reference to the drawings.
