The present invention relates to a method for manufacturing a shantan-like yarn using a continuous multi-filament yarn. Conventionally, slub yarns having thick and thin yarns in the longitudinal direction have been widely used as an effective means for changing the appearance of fabrics. In particular, in recent years, reflecting the natural fiber-oriented market, approaches have been made to these yarns from continuous multi-filament yarns, and many proposals such as Japanese Patent Publications No. 45-16895, No. 45-28018, No. 47-49459, and No. 50-35147 have been made. being done. However, in both methods, the process is heat-set in the twisting region during twisting, resulting in a crimped yarn, and it is necessary to maintain a high false-twisting temperature in order to improve the cohesiveness of the two yarns. This is particularly undesirable when obtaining a silky texture. Furthermore, for the same reason, this is not an appropriate method when using, for example, a differentially shrinkable mixed fiber yarn that is currently evaluated to be the silkiest. On the other hand, in Japanese Patent Publication No. 51-30174, there is a proposal to form countless loops of filaments of wound yarn around the core yarn without heat-setting in the twisting area, and when heat-setting is not done, normal conditions are applied. The figure below suggests that the resulting yarn has a looped form. Therefore, the resulting fabric has loops protruding from the surface, and even if it has a silky feel, it will have a completely different appearance from a shantung made of real silk. The present inventors paid attention to this point and conducted various studies, and as a result, they discovered that under certain specific conditions, a slub yarn with substantially no loops can be obtained. The gist of the invention is that the core yarn A, which is made of a multi-filament yarn that has been false-twisted by a false-twisting method that does not perform heat fixation in the twisting region, has other multi-filament yarns in the twisting region. When winding yarn B, the twist coefficient ((
α)) is 15500 to 10600, and the twist coefficient of yarn B
((β)) is 1100 to 0, and the twisting direction of yarn B is not the same as the twisting direction of yarn A. However, α=T AA , β=T BB , and T A
is the number of twists (T/M) when yarn A is false twisted alone, D
A is the denier of yarn A, similarly T B and D B are yarn B
It is related to. A detailed explanation will be given below with reference to the drawings. The figure is a side view showing an example of an embodiment used for carrying out the present invention. In the figure, multi-filament yarn A is false-twisted by a false-twisting spindle 3 installed between the first supply roll 1 and take-up roll 2. , while the second supply roll 4
The multifilament yarn B is fed to the twisting area of the system A. Since the object of the present invention is a substantially loop-free slub yarn having a silky texture,
It is necessary to avoid heat setting in the twisting region in order to obtain a preferable texture. However, the Tokuko Sho 51
-30174, the yarn obtained under normal conditions has loops, which gives the appearance of protruding loops on the surface of the fabric, which is undesirable for expressing a shantung appearance. The present inventors investigated various methods of reducing loops while applying slabs, and obtained the results shown in Table 1.

[Table] From the results in Table 1, the following became clear. In other words, the number of twists (twist coefficient) of yarn A in the twisting region shown in the figure, the number of twists (twist coefficient) of yarn B that is twisted to yarn A that is being twisted, and the twist rate of yarn A. The direction and the twisting direction of yarn B have a very large influence on the loop generation and slab form, and the preferable conditions are that the number of twists of yarn A is 2200 to 1500 T/M (twisting coefficient is 15556 to
10607 However, twist coefficient = number of twists (T/M) x √ denier of yarn, and the number of twists of yarn B is 156 to 0
T/M (twist coefficient: 1103 to 0), and the most preferable condition is that the twist coefficient of yarn A = 14142 to 0.
10610, the twist coefficient of yarn B is 848 to 0, and the important conditions are that the twisting direction of yarn A and the twisting direction of yarn B are not the same. The reason for this is not clear, but the number of twists in yarn A affects the difference in yarn length per unit length between yarns A and B after untwisting, and therefore regulates the appropriate range for maintaining cohesiveness. This seems to be a synergistic effect to maintain convergence by preventing the torques of yarns A and B after twisting and untwisting from being at least in opposite directions. This will be explained in more detail in Examples below. Example 1 A polyester yarn of 100 denier/48 filaments and 12 T/M (S twist) was used as yarn A, and a non-twisted polyester yarn of 72 denier/36 filaments was used as yarn B. Thread A
Twisting number 1300T/M, twisting direction Z, twisting tension 10g,
When Yarn B was processed at an overfeed rate of 70%, a good slanted yarn with substantially no loops and a slab shape was obtained. Example 2 The same yarn as in Example 1 was used as yarn A, and yarn B
as 50 denier/24 filaments, number of twists 120T/
When M (S twist) polyester yarn was used and processed using the equipment shown in the figure under the same conditions as Example 1,
A good slanted yarn with a substantially loop-free slab form was obtained. Comparative Example When processing was carried out under the same conditions as in Example 2 except that the number of twists of yarn B was 50T/M (Z twist), a clear loop was formed around the obtained yarn.
