The present invention relates to a novel special false-twisted yarn, and the gist of the invention is that a real twist portion is formed along the longitudinal direction of a thermoplastic synthetic multifilament yarn in the same direction as the false-twisting direction. , the false-twisting/untwisting direction and the actual twisted portions in the same direction exist alternately with untwisted crimped portions interposed therebetween, and the length of each actual twisted portion and the untwisted crimped portion is each 10 cm or more. The special feature lies in the special false twisted yarn. Hereinafter, the present invention will be explained in detail with reference to the drawings. Fig. 1 is a side view of a special false-twisted yarn according to the present invention in which the false-twisting direction is the Z direction, and in the same figure, 2 is the false-twisting direction. 3 indicates a real twist part (Z twist), and 3 indicates a real twist part (S twist) in the false twist/untwist direction. The real twist parts 2 and 3 exist alternately through the non-twisted crimped part 4 or 4'. However, the length of each part is at least 10 cm. Further, there is no fused portion in the actual twist portions 2 and 3. As shown in FIG. 2A, there is a difference in the number of twists within the area of the actual twisted part 2, with the area near the non-twisted crimped part 4 having a lower number of twists. This also applies to the actual twisting section 3. Furthermore, as shown in FIG. 2B, there may be a difference in the maximum value between the actual number of twists in the twisting direction and the actual number of twists in the untwisting direction. In the special false-twisted yarn of the present invention, parts with real twists in different directions exist alternately through non-twisted crimped parts, but the real twisted part is compared with the non-twisted crimped part. However, since the yarn has a cohesive property due to real twisting, when dyed, the real twist part appears dark colored. Moreover, because there is a difference in the number of twists even within the actual twist area, the shade of dyeing appears to change continuously from the untwisted crimped area to the area showing the maximum number of twists within the actual twist area, and the hue change can be observed with a single thread. I can put it out. Such a hue effect of the yarn becomes even more effective by providing a difference in the maximum number of twists between the actual twist portions 2 and 3. Furthermore, since the actual twisted part and the non-twisted crimped part each have a length of at least 10 cm or more, the hue effect can be further enhanced.At the same time, due to the convergence of the real twisted part, the actual twisted part has a better appearance than the non-twisted crimped part. It becomes thinner and has a difference in thread form, which can also produce a thread form effect. Since there is no fused part in the real twist part, it is possible to produce a woven or knitted fabric with a soft texture. The special false-twisted yarn according to the present invention can be obtained by changing the rotational speed of the false-twisting spindle during normal false-twisting. That is, in the apparatus shown in FIG. 3, the filament yarn 9 is normally twisted and heat-fixed from the feed roller 5 through the first heater 6 to the spindle 7, and the yarn coming out of the spindle 7 is untwisted and sent out from the delivery roller 8. . Here, when the spindle rotation speed is constant, the number of twists and the number of untwists are constant and balanced, so in the untwisting region, a three-dimensional crimp corresponding to the number of twists is formed, resulting in a uniform winding. A shrunk yarn will be produced. However, when the spindle rotation speed changes, when the twisting direction is Z twist, the feed roller 5 and spindle 7
The false twisted yarn that is Z-twisted and heat-set by the heater 6 at the same time is untwisted with a different number of twists than the number of twists added to the Z-twist. A numerical imbalance occurs. For example,
Taking into consideration the temporal change of yarn transfer, we consider the situation where the spindle rotational speed is increasing.
A spindle in which untwisting is applied that is greater than the number of twists applied in the twisting region, and this difference in the number of twists remains as the actual number of twists in the untwisting region, forming an untwisting direction actual twisting section 3. Considering the situation where the number of rotations is decreasing, conversely, in the untwisting region, only the number of twists added in the twisting region is less than the number of twists added, and this difference in the number of twists is calculated as the actual number of twists in the untwisting region. This will remain, and a real twist portion 2 in the twisting direction will be formed. On the other hand, when the spindle rotation speed changes from a decrease to an increase (or from an increase to a decrease), the number of twists in the twisting region and the untwisting region match, and during this period, the normal untwisted crimped section 4 ( or 4') is formed. When the spindle rotation speed changes from increasing to decreasing, the untwisted crimped part has a high number of twists, so the crimped form is dense.
Since the number of twists in the non-twisted crimped portion 4 changes from decrease to increase, the number of twists is low, so the crimped form has a high torque. Therefore, the crimp characteristics of the non-twisted crimped portions 4 and 4' are different when the spindle rotational speed increases from decreasing to increasing and when the spindle rotational speed increases from increasing to decreasing. By varying the amplitude of the spindle rotation speed, which changes from decrease to increase and from increase to decrease, the maximum twist of the actual twist area in the false-twisting direction and the actual twist area after false-twisting and untwisting is determined as shown in Figure 2B. At the same time as the difference in number occurs, it becomes possible to form more than two types of crimp characteristics of the non-twisted crimped portion. For example, the spindle rotation speed can be changed by changing the rotation of the spindle belt. One specific example of this method is to vary the rotational speed of the spindle belt drive motor, but the method is not limited to this method. The special false-twisted yarn of the present invention has an essentially different yarn structure from the SZ alternating yarn, which is false-twisted at a high temperature above the softening point like conventional yarns, such as the length of each actual twist part and the absence of fused parts. It can produce unique features in terms of hue and form effects. Next, examples of the present invention will be shown. Example Using polyester filament yarn SD150a/72f, the spindle rotation speed was 9.8×10 4 rpm to 18.8×
False twisting was performed by varying the speed up to 10 4 rpm as shown below.
