ージ内層、中層、外層の応力分布と、繊維自体の内部歪
みの緩和に影響を受ける。When dry-spun fibers are wound by a ring winder, the collapse of the wound yarn package is affected by stress distribution in the inner layer, middle layer, and outer layer of the package and relaxation of internal strain of the fiber itself.

When T2 / T1 exceeds 2.4, the tension applied from the middle layer to the inner layer is too large,
Occurrence of roll collapse occurs. On the other hand, when T2 / T1 is less than 1.3, the stress for tightening the take-up tube in the radial direction is too small, and thus collapse of the winding occurs. In addition, 1.5 <T2 / T1 <2.2 is more preferable from the viewpoint of improving stability against winding collapse.

い。When T3 / T2 exceeds 1.65, the tension applied to the yarn of the outer layer is too large, and the winding collapse occurs. On the other hand, when T3 / T2 is less than 1.00,
Winding collapse occurs because the stress tightening in the radial direction of the take-up tube is too small. It is more preferable that 1.25 <T3 / T2 <1.61 from the viewpoint of improving stability against winding collapse.

It is preferable that 5 × Vb × 100) / 60 ≦ 250. mt x (Vs-5 x Vb x 100) / 60 is 250
If it exceeds, the tension applied to the yarns of all the layers is too large, and the stress of the yarn layers tightening in the radial direction of the winding tube is too large, so that the inner layers are loosened and the winding collapse easily occurs. On the other hand, mt x (Vs-5 x Vb x 100) /
When 60 is less than 150, the stress that the yarn layer tightens in the radial direction of the take-up tube is too small, and thus winding collapse easily occurs. By satisfying the conditions, it is possible to increase the winding amount and to wind the yarn at high speed. Further, from the viewpoint of improving stability against winding collapse, 160 <mt × (Vs-5

ことが好ましい。The spinning dope may be the same as that used in ordinary dry spinning, and the higher the solid content in the spinning dope, the more preferable it is to reduce the residual solvent ratio contained in the yarn. Since increasing the solid content increases the viscosity of the spinning dope, it is preferable to add a plasticizer.
