For example, in Japanese Examined Patent Publication No. 3-66410, an alternate untwisted yarn is obtained by subjecting a single unstretched yarn to false twisting, and then binding the filaments together with the residual twist in the false twisting twisting direction and the twist in the false twisting untwisting direction. Processed yarn has been proposed.

によって伸縮性を著しく低下させる欠点があつた。However, according to the method described in Japanese Patent Publication No. 3-66410, a sharpness can be obtained, but since the filaments are tightly bundled in the alternate twisting and the fusion, the stretchability is reduced. It is almost nothing.
Further, the processed yarn described in Japanese Patent Publication No. 62-21883 has bulkiness due to the slack of the sheath yarn, but has the drawback of remarkably decreasing the elasticity due to fusion of the core portion.

The untwisted portion C is a portion in which the A and B yarns are strongly twisted together in the false twisting twisting direction, and a linen-like crispness is exhibited by the partial fusion of the low melting point yarn B. . The spread portion D is substantially untwisted, is sufficiently provided with false twist crimps, and is a portion that contributes to the stretchability and bulkiness of the yarn. The over-untwisted portion E is bundled by twisting in the false-twisting and twisting directions opposite to the false-twisting and twisting directions, but is less than 1/2 of the twist as compared with the untwisted portion C described above. , Which is a part mainly contributing to the elasticity of the yarn.

It is repeatedly present as a morphological unit, but morphological units such as CED and CEDE are randomly mixed before and after the basic morphological unit. Unless they are randomly mixed like this,
The unevenness resulting from the difference in yarn structure and morphological difference between the untwisted portion C, the spread portion D, and the overtwisted portion E is not dispersed, and the surface becomes asymmetric when formed into a woven or knitted fabric.

When it is woven or knitted, if it is less than 7%, the sharpness is enhanced, but the stretchability and bulkiness are reduced, and the coarseness and hardness are enhanced. On the other hand, if it exceeds 22%, the sharpness is lowered, and the texture is close to the texture of a normal false twisted yarn having a feeling of sticking and warping, which is not preferable.

長さの平均を４〜１５mmとするのが好ましい。In the partially fused composite false-twisted yarn of the present invention, the average length of the untwisted portion C is easily broken by the tension and ironing in the weaving / knitting process, and the process passability is deteriorated. From the viewpoint of preventing unevenness and unevenness on the surface of the woven or knitted fabric due to the difference in yarn structure between the untwisted portion C and the open fiber portion D or the overtwisted portion E, and the difference in form, The average length of the untwisted portion C is preferably 4 to 15 mm.

利点をも有する。In the partially fused composite false twisted yarn of the present invention, the melting point temperature can be easily changed depending on the copolymerization amount of the third component, and the combination of the melting point difference with the high melting point yarn can be used in the present invention. It is preferable to use the low-melting-point yarn as a copolyester since it can be arbitrarily set within the range and stability of false twisting and easiness of dyeing can be obtained by using the same type of polymer. In addition, as a side effect, in dyeing woven and knitted fabrics,
In combination with cationic dyeable polyester,
It also has an advantage that a color effect such as a different color due to different dyeing of an acid dye and a cationic dye or a shade effect due to only the cationic dye can be aimed at.

In addition, the untwisted portion and the overtwisted portion are bundled by twisting even in the post-process of weaving and knitting, and thus the process passability is excellent.

FIG. 2 shows one embodiment of the method for producing a partially fused composite false twisted yarn of the present invention.

Then, the false twisting process is performed between the take-up roller 4 and the take-up roller 4 by the twisting device 3 and the heater 2. If necessary, the yarn subjected to the fusion false twisting process is heat-treated by the second heater 5 between the take-up roller 4 and the second take-up roller 6 to reduce the false-twisting torque, and then the winding package.

に伸縮性の乏しい融着糸条とになる。In the method of producing the partially fused composite false twisted yarn of the present invention, two types of highly oriented polyester unoriented yarns are used, and the difference in melting point is 3 to 10 ° C. When the difference in melting point is less than 3 ° C., the difference in melting point between the yarns A and B is close to each other. Therefore, when the false twisting process is performed, not only the low melting point yarn B but also the high melting point yarn A are fused, The yarns A and B are integrated to form a fused yarn having poor elasticity. The melting point difference is 1
If the temperature exceeds 0 ° C., in order to impart the false twist crimp to the high melting point yarn A and obtain the elasticity required in the present invention, the heater temperature is close to the temperature required for the yarn A to be thermoplasticized. To be
Since the filaments of the low melting point yarn B are easily fused and integrated, a fused yarn having poor stretchability is obtained.

When the NDR difference exceeds 30%, a core / sheath two-layer structure in which one of the yarns A and B having a small natural draw ratio constitutes a core, and conversely a yarn having a large natural draw ratio constitutes a sheath. Since it is a fusion-bonded yarn close to, the stretchability is reduced.

る。In the method for producing a partially fused composite false twisted yarn of the present invention, a drawn false twisting process is performed, but the temperature is higher than the melting point of the low melting point yarn by 35 ° C. and higher than the melting point of the high melting point yarn. A part of the low-melting point yarn is fused at a low false twisting temperature and subjected to draw false twisting. 35 from the melting point of the low melting point yarn
Unless the temperature is lower than the temperature lower than ℃, a part of the low melting point yarn cannot be fused. On the other hand, unless the temperature is lower than the melting point of the high-melting point yarn, not only the low-melting point yarn but also the high-melting point yarn are fused and the two yarns are integrated to form a fused yarn having poor elasticity.

It is possible to produce a false twist textured yarn.
