〈産業上の利用分野〉
本発明は高強力のポリエステル太細糸の’１１１３ｎ方

る。Detailed Description of the Invention <Industrial Field of Application> The present invention relates to the '1113n method for producing high-strength polyester thick and fine yarn, and more specifically, it relates to the production of high-strength polyester yarn with a special texture in industrial applications. The present invention relates to a method for producing thick and fine polyester yarn suitable for use as a base fabric for coating, which has improved physical adhesion to knitted fabrics and coating materials.
〈従来の技術〉
従来よりポリエステル太細糸は特殊な風合をもたせるた
めに種々の方法が提案され、実用化されている。<Prior Art> Various methods have been proposed and put to practical use in order to give thick and thin polyester yarns a special texture.
例えば紡糸口金の孔径を変えて単糸間に太細糸を混在さ

提案されている。しかしながら、いずれの方法も、衣料
用途に適した素材であるために強力が低く、しかも特殊
な製糸プロセスをとるために生産コストが割高である。For example, a method in which thick and thin yarns are mixed between single yarns by changing the hole diameter of the spinneret, a method in which yarns discharged from different spinnerets at different discharge rates are combined and wound, a method in which the spinning speed is pulsated, etc. is proposed. However, in either method, the strength is low because the material is suitable for clothing use, and the production cost is relatively high because it requires a special spinning process.
本発明者等は衣料用の低強力糸でなく、広〈産業用途に

殊な製糸条件を採用することにより簡単に太細糸が得ら
れることを見い出し、本発明に至った。The inventors of the present invention have conducted extensive research on a method of manufacturing not only low-strength yarn for clothing, but also high-strength thick yarn that can be applied to a wide range of industrial applications at low cost without adding special processes, and It was discovered that thick and thin threads can be easily obtained by adopting certain conditions, leading to the present invention.
〈発明の構成〉
本発明は極限粘度０．６以上のポリエステルを１０以上

３以上になすことを特徴とするポリエステル太細糸の＊
遣方法である。<Structure of the Invention> The present invention involves melting and discharging polyester having an intrinsic viscosity of 0.6 or more from a spinneret having 10 or more spinning holes at a discharge linear velocity of 15 cm/sec or less, quenching it, and then taking it off at a speed of 600 to 3000 m/min. Polyester thick/fine yarn characterized by having a thick/fine ratio of 3 or more by subsequently hot-stretching and winding.
It is a method of sending.

ロセスを付加することなく簡便に太細糸を得ることにあ
る。更に本発明の特徴は、高重合度のポリエステルの使
用により延伸後の糸条の強力を高く維持できることにあ
る。The feature of the present invention is that when melting and discharging polyester with a high degree of polymerization, the discharge linear velocity is extremely low and it is rapidly cooled to induce a draft ring in the thinning process, thereby adding a special process unlike the conventional one. The objective is to easily obtain thick and thin threads. A further feature of the present invention is that the strength of the yarn after drawing can be maintained at a high level by using polyester with a high degree of polymerization.
重合度即ち極限粘度が低いと、強力が高く保持できない
のみでなく、ドラフト環による太細比が大きくとれない
ため０．６以上の極限粘度が必要であり、好ましくは０
．７以上、更に好ましくはＯ８８以上の極限粘度である
。If the degree of polymerization, that is, the intrinsic viscosity is low, not only will it not be possible to maintain high strength, but also the draft ring will not be able to maintain a large thick-to-thin ratio, so an intrinsic viscosity of 0.6 or more is required, preferably 0.
．． The intrinsic viscosity is 7 or more, more preferably O88 or more.
吐出線速度は１５■／秒以下となすことが必要である。It is necessary that the discharge linear velocity be 15 .mu./sec or less.
これより吐出線速度が大きくなると、本発明に必要な特
殊なドラフト斑を惹起することがない、その下限は極限
粘度、引取速度等に影響されるが、通常５（２）／秒程
度である。If the ejection linear velocity is higher than this, the special draft unevenness necessary for the present invention will not occur.The lower limit is usually around 5(2)/sec, although it is influenced by the intrinsic viscosity, take-up speed, etc. .
また、吐出された糸条を［１金直下で急冷することがド
ラフト環を惹起させるために必要である。In addition, it is necessary to rapidly cool the discharged yarn just below [1 gold] in order to induce draft rings.
急冷条件としては口金下数ａｎ〜１０（２）以内で冷却
風を吹き出すことが必要である０口金直下の雰囲気を加
熱するとドラフト環が発現し難くなるので、単なる断熱
板を介してスピンブロックとの間をシールすることが望
ましい。As a rapid cooling condition, it is necessary to blow cooling air within a few an to 10 (2) below the cap. 0 If the atmosphere directly under the cap is heated, it becomes difficult to form a draft ring, so the spin block and It is desirable to seal between.
本発明で得られる太細糸は、任意の部位で断面をカット
して単糸間の直径比を観察すると少くとも３以上の太細
比を有しており、著しい組み合せでは、８以上となるも
のも製糸可能である。特に極限粘度が０．８以上の組み
合せでは１０以上のものも製糸でき、この場合巻取時に
太細間の弾性回復差によると思われる糸長差が生じ、ス
パンライク状となる特徴を有する。The thick/thin yarn obtained by the present invention has a thick/thin ratio of at least 3 or more when the cross section is cut at an arbitrary part and the diameter ratio between single yarns is observed, and in significant combinations, it is 8 or more. It is also possible to spin yarn. In particular, in combinations with intrinsic viscosity of 0.8 or more, yarns of 10 or more can be produced, and in this case, during winding, a difference in yarn length appears due to the difference in elastic recovery between thick and thin yarns, resulting in a spun-like characteristic.
引っ張り強度も６．５ｓｒ／ｄ以上とすることが容易で

取速度は６００ｍ／分未満になるとドラフトが少いため
にドラフト環が小となり、太細比が小さくなる。また、
逆に３０００ｍを越えるとドラフトが大きくなり単糸切
れを誘発するために製糸性が低下する。The tensile strength can also be easily set to 6.5 sr/d or more, which is sufficient for industrial use. When the take-up speed is less than 600 m/min, the draft ring becomes small because there is little draft, and the thick-to-thin ratio becomes small. Also,
On the other hand, if the length exceeds 3000 m, the draft becomes large and single yarn breakage is induced, resulting in a decrease in spinning performance.
